Select Committee on Environmental Audit Minutes of Evidence


Memorandum submitted by the British Energy Group plc

I.  SUMMARY

A.  THE EXTENT OF THE "GENERATION GAP"

  1.  The electricity supply sector is set to undergo a major transition over the next two decades. Decisions over the next five years will determine the nature of this transition.

  2.  Significant new capacity will be needed to replace about 160 TWh of existing generation which will likely be retired over the next 15 years; in any event, further new capacity will be needed to satisfy increased demand over the same period amounting to about 44 TWh. To put these into context, the sum of the "new" generation required amounts to about 58% of the generation in 2004; assuming the current generation mix this would be equivalent to about 42 GW of plant.

  3.  There is considerable uncertainty in the way the markets will work in the next few years and it is not yet clear that market signals will encourage the required investment in a timely way. Further, any market signal would have to encourage investment in plant of differing load factors to match the daily and seasonal demand profiles and to provide sufficient capacity headroom to "replace" plant that becomes unavailable due to planned and unplanned outages.

B.  FINANCIAL COSTS AND INVESTMENT CONSIDERATIONS

  4.  There have been many studies on the relative costs of different generation options. In general these have shown that nuclear can be cost-competitive. Most recently the UK's Royal Academy of Engineers has carried out a thorough analysis of the cost of generation for all technologies using information drawn from around the world (although the cost of gas assumed in their analysis is about half that prevailing today). They have included in this work the cost of carbon to the fossil technologies of coal and gas, and the cost of providing standby plant for intermittent generation (wind). When expressed in terms of p/kWh, nuclear generation is competitive with current benchmark CCGT technology and cheaper than the other options.

  5.  Financial Institutions around the world have shown themselves willing to invest in all forms of generation, including nuclear. In the UK the investment community is most concerned with a "transparent measurement of risk-return profile ie markets will bear measurable risks against acceptable return levels".

  6.  It is not clear what—if any—direct financial support will be needed from the Government in order for private sector investment in new nuclear build to take place. Before it is possible to form a view on this question, it is necessary to assess the options to address particular classes of risk and to identify the extent that the private sector is able to take these risks without Government financial support.

C.  STRATEGIC BENEFITS

  7.  Nuclear power brings a number of benefits to the UK including the provision of large quantities of emissions-free electricity, a contribution to security-of-supply, and can help mitigate electricity price volatility.

  8.  Nuclear power arguably makes the biggest contribution to the UK's climate change targets. In 2004, 73.7 TWh of nuclear generation avoided the emission of about 49 MtCO2 that would otherwise been emitted by the prevailing fossil fuel mix. To put this into context, about three quarters of all the cars on the roads would have to be removed to get the same climate change savings as those associated with nuclear generation. This emissions-free generation will have to be replaced if these benefits are not to be lost.

  9.  Nuclear power contributes to UK security-of-supply (SOS). Using the Government's own projections the sum of "indigenous" generation as a percentage of the total is seen to decline from almost 100% in 1990 to about 50% by 2020 and just 25% by 2030, primarily due to an increased reliance on imported gas. New nuclear build to the level indicated in the EAC's Inquiry will increase this index from 25% to 45%. Further, nuclear generation results in the avoided consumption of significant quantities of gas, again improving the UK's SOS position. Finally, keeping the nuclear option improves the reserve margin, helping to mitigate the risk of electricity supply disruptions.

D.  OTHER ISSUES

  10.  An independent full life-cycle analysis has recently been carried out of British Energy's nuclear AGR plant at Torness using a well established methodology. This work shows that for all intents and purposes nuclear generation can be considered carbon dioxide free when compared to coal and gas technologies.

  11.  There has been considerable progress in resolving the nuclear waste issue in a number of countries, including Finland, Sweden and USA. In the UK, the Committee on Radioactive Waste Management (CoRWM) has been established to bring forward concrete proposals for dealing with legacy and ongoing waste streams when it reports to Government in July 2006. The Government then needs to establish the policy framework and implementation plan to deliver its preferred solution to this problem for the industry and country.

  12.  Recent work has established that the amount of waste from a new build programme on the scale proposed will add very little to the waste that in any event needs to be dealt with—the legacy of past military and civil programmes. The facility built to deal with the legacy waste can be designed to accommodate the extra waste from a new build programme. New nuclear build can be progressed in parallel with the siting and building of the long term repository.

II.  RESPONSE TO QUESTIONS

A.  THE EXTENT OF THE "GENERATION GAP"

1.   What are the latest estimates of the likely shortfall in electricity generating capacity caused by the phase-out of existing nuclear power stations and some older coal plant? How do these relate to electricity demand forecasts and to the effectiveness of energy efficiency policies?

    (a)  Figure 1 shows that demand in recent years has been satisfied by a mix of coal, gas and nuclear, with only a minor contribution from a renewables and imports. The future of the sector is hard to predict but what is certain is that it is set to undergo a major transition over the next 10 to 15 years brought about by increasing demand and a decline in coal and nuclear generation as new environmental policy initiatives and old age lead to plant closures. Significant new capacity will be needed to replace existing plant which currently supplies about 160 TWh but will likely be retired over the next 15 years; even if this is not the case, further new capacity will be needed to satisfy increased demand over the same period amounting to about 44 TWh. To put these into context, the sum of the "new" generation required amounts to about 58% of the generation in 2004, and based on the current mix this is equivalent to about 42 GW of plant.

    (b)  The DTI's Energy Paper 68 and its various updates set out projections for the UK energy scene to 2020. No "generation gap" is predicted from this work with the supply dominated by gas technology. The projections make important assumptions including:

      —  Supply is automatically provided to deliver the required demand with the lowest cost technology the preferred option.

      —  Energy efficiency will help limit demand.

      —  The Renewables Obligation will deliver 10% of supply by 2010 and 15% by 2015.

    (c)  However, the generation sector may not evolve in this manner because:

      —  Fossil fuel prices in general, and gas prices in particular, are higher than expected and look set to stay at these levels for the foreseeable future raising the cost of the benchmark technology (gas). These costs must be passed onto the consumer if new build investment is to be encouraged.

      —  Renewables and energy efficiency are not delivering on the scale anticipated despite major subsidies. NGT assumptions are of a 1.3% per annum increase in demand to 2012; new CHP and renewables supply over the same period serve to reduce the growth in demand on the grid to 0.8% per annum.

      —  The EU Emissions Trading Scheme will place additional costs on fossil generation raising the barrier for new gas (and coal) build. The Large Combustion Plant Directive will accelerate retiral rates for the older coal plant. Assuming 80% of the existing coal plant shut post-2015 about 108 TWh of flexible coal generation may need to be replaced (in addition to the 53 TWh of nuclear generation).

      —  The UK will be importing the majority of its fossil fuel needs to support the generation sector and could be subject to fuel supply disruptions and/or cost volatility.

      —  There is considerable uncertainty in the way the markets will work in the next few years—there is very little new build fossil plant underway and it is not yet clear what market signals will encourage such investment in a timely way. Further, any market signal would have to encourage investment in plant of differing load factors to match the daily demand profile and to provide sufficient capacity headroom to "replace" plant that becomes unavailable due to planned and unplanned outages.

    (d)  For these reasons, it is entirely possible that a convergence of events could lead to a "generation gap", the scale of which would depend on the severity of the events, and lead to costly electricity supply disruptions—the supply industry and Government have important decisions to make over the next five years.

B.  FINANCIAL COSTS AND INVESTMENT CONSIDERATIONS

2.   What are the main investment options for electricity generating capacity? What would be the likely costs and timescales of different generating technologies?

  The main investment options and their likely contribution to the generating mix are as follows:

    (a)  Gas—remains the preferred option because of the relative ease of delivering new capacity onto the market; whether the capacity will be forthcoming will depend on a number of factors over the next decade or so, including the certainty or otherwise of gas supplies, the cost of carbon, and the reserve margin.

    (b)  Coal—investment in conventional coal technology is unlikely because of the severe environmental conditions that must be met; investment in new IGCC and "clean" coal technology (ie plant fitted with Flue Gas De-sulphurisation technology to remove SOx, low NOx burners and Carbon Capture and Sequestration to address carbon dioxide emissions) is possible but at a much higher cost to the consumer.

    (c)  Oil—investment in this technology is unlikely because it is no longer cost competitive against the benchmark technology, gas.

    (d)  Nuclear—investment in this technology is possible depending on electricity prices ie this option becomes more favourable as the electricity price rises, particularly if the latter is brought about by higher gas (and coal) prices, and the cost of removing sulphur and nitrogen oxides and carbon dioxide are factored into the running costs for the fossil technologies. Prospects for this technology will also increase with more certainty on waste, and a clear signal of government commitment.

    (e)  Renewables—government has taken a long term view of these technologies and provided significant subsidies to encourage their development. With this in mind more wind (both onshore and offshore) is possible; biomass can contribute but is more expensive than wind and the Renewables Obligation does not provide the differential support needed to encourage investment in this technology in preference to onshore wind at this time; PhotoVoltaic technology will remain a niche player at best in the short to medium term while marine technologies are at the early stages of their development and if they are to contribute at all, they will only do so in the longer term.

What are the likely construction and on-going operating costs of different large-scale technologies (eg nuclear new build, CCGT, clean coal, on-shore wind, off-shore wind, wave and tidal) in terms of the total investment required and in terms of the likely costs of generation (p/kWh)? Over what timescale could they become operational?

    (a)  There have been many studies on the relative costs of different generation options. In general these have shown that nuclear can be cost-competitive. Most recently the UK's Royal Academy of Engineers has carried out a thorough analysis of the cost of generation for all technologies using up-to-date information. They have included in this work the cost of carbon to the fossil technologies of coal and gas, and the cost of providing standby plant for intermittent generation (wind). Figure 2 suggests that when expressed in terms of p/kWh, nuclear generation is competitive with current benchmark CCGT technology and cheaper than the other options.

    (b)  Renewed interest in the nuclear option has spawned a number of studies on the economics of new nuclear build (including the RAE work) and these are summarised in Figure 3. Despite the fact that these studies have been carried out by various independent groups, and in different countries, they show remarkable consistency. The key difference is the rate of return applied. Many of these studies have also found that nuclear is competitive with the benchmark CCGT technology; when the cost of carbon is added to the latter the comparative benefit of nuclear to consumers is greater.

    (c)  Table 1 attempts to illustrate the timescales over which the various technologies could be deployed to the level indicated in the Inquiry (ie for nuclear, 8 AP1000 or their fossil equivalent; for each renewable technology a significant contribution towards a 20% supply target (the approximate amount equivalent to that from 8 AP1000)).

    (d)  On a short time-scale only gas and conventional coal technology can be built to the scale required. If "clean" coal means plant that is totally emissions free, this could be achieved over a 20 year period subject to the development of coal import infrastructure and the successful development of carbon capture and sequestration technology.

    (e)  Although nuclear plant can be built in five years, past UK experience suggests that another five or more years will be needed for planning and licensing, even if the intent were to build accepted international design on sites already designated safe for nuclear generation. Government would have to address these issues to ensure a shorter pre-build time frame. It is possible to construct 8 GW of nuclear plant over a 12-15 year period.

    (f)  To deliver a portfolio of renewables requires a much longer time frame for the reasons outlined elsewhere in this submission.

With regard to nuclear new build, how realistic and robust are cost estimates in the light of past experience? What are the hidden costs (eg waste, insurance, security) associated with nuclear? How do the waste and decommissioning costs of nuclear new build relate to the costs of dealing with the current nuclear waste legacy, and how confident can we be that the nuclear industry would invest adequately in funds ring-fenced for future waste disposal?

    (a)  The numbers shown in Figure 2 are robust when considering new build in the UK because:

      —  They have been validated by independent groups on the most up-to-date information. There may be uncertainty associated with vendor quotes for projects but these can be largely removed through fixed price quotes.

      —  The programme will not use a prototype technology—the "winning" technologies have emerged (ie the AP 1000, EPR and Candu designs). New plant will be smaller, less complicated than before, based on "off-the-shelf" modular systems.

      —  New plant has a much smaller ecological footprint and will adhere to international standards of safety and operating regime. Figure 4 compares an early Magnox station at Chapelcross in the UK, a 200MW station which started generating electricity in 1959 and closed in June 2004, with the new fifth reactor in Finland, a 1600 MW station expected to begin generating electricity in 2009. The new reactor in Finland is not only physically much smaller but it also produces much less waste than the early reactors in the UK.

    (b)  The "hidden" costs are conservatively allowed for in the estimates of the cost of nuclear generation. Addressing the specific concerns in the question:

      —  Waste. The UK needs a repository to deal with its legacy waste, including that from its civil programme. A process to deliver a solution to the waste issue has begun with the establishment of the Committee on Radioactive Waste Management (CoRWM). The latter is charged with investigating all options and to deliver its Report to Government in July 2006. There is an expectation that Government can then establish its policy on this issue followed by a detailed implementation plan. A new build programme can progress in parallel with the siting and building of the final waste repository.

        The waste addition associated with a replacement programme is relatively small and can be factored into repository requirements at an early stage. Even so, it will require industry and Government to establish the arrangements and cost of waste disposal from any new build programme.

      —  Insurance. Under the UK's Nuclear Installations Act the operator has to provide cover for an aggregate limit of £140 million per site; any shortfall must be paid for by Government. These requirements are being revised in light of amendments to the Paris Convention and the supplementary Brussels Convention. The liability to the nuclear operator will now be

700 million—the liability of the Government will be

500 million and the liability of the pool of funds contributed to by contracting parties will be

300 million [11].

      —  Security. The industry pays for its own security, following government guidelines, and taking note of international best practice.

    (c)  It is widely accepted that the cost of decommissioning is not a major contribution to the overall cost of nuclear power. New plants such as the AP1000 have a much smaller ecological "footprint" which means this part of the project is an even smaller contribution to the total cost than before. Nonetheless, industry will be expected to cost this activity as part of its project proposal and it will require Government to deliver its preferred long term waste solution.

Is there the technical and physical capacity for renewables to deliver the scale of generation required? If there is the capacity, are any policy changes required to enable it to do so?

    (a)  The Government has a target of 10% of supply by 2010 and 15% by 2015—in 2004 the figure was 4% with main contributions to this number being hydro (1.35%), landfill gas (1.16%) and wind (0.5%).

    (b)  British Energy is developing wind projects in joint ventures that if successful will deliver up to 700MW capacity. This is of a similar magnitude to the total wind capacity currently in the UK and would thus contribute about 0.5% to the UK targets.

    (c)  Technical capacity. Onshore wind and to a lesser extent biomass are available but offshore wind still needs some development for the UK situation. It is not clear what this level of "intermittent" generation means for grid stability. Lessons learned from elsewhere suggest there is a limit to the maximum level of "intermittency" possible but the lack of physical connectivity across national boundaries means the UK is more vulnerable than other European countries to this problem.

    (d)  Practical capacity. Despite significant subsidies the 10% target by 2010 and 15% target by 2015 look very challenging.

    (e)  Despite the provision of generous subsidies, there are two fundamental flaws to the Renewables Obligation (RO) that serve to limit its potential—projects become increasingly less attractive as the RO is reached, and it cannot provide the stimulus to technologies that are more expensive than wind, or are some way from market commercialisation.

What are the relative efficiencies of different generating technologies? In particular, what contribution can micro-generation (micro-CHP, micro-wind, PV) make, and how would it affect investment in large-scale generating capacity?

    (a)  The thermal efficiencies of the various fossil plant are reasonably well established. However, it is not meaningful to compare nuclear and fossil thermal efficiencies. The only purposes for comparing efficiencies would be if it gave an indication of relative costs or resource use, and since these technologies use radically different fuels it is not possible to draw these comparisons from efficiency data.

    (b)  The development of micro-generation systems requires a different kind of technical, practical and financial capacity than for the more established renewables technologies. It is then a long-term "project" for the UK and as such will contribute very little in the next 10-20 years.

    (c)  Many of the decisions for investment in new large-scale generating capacity will have to be made over the next 10 years or so—any modest development of the micro-generation sector is unlikely to have an impact on these decisions.

3.   What is the attitude of financial institutions to investment in different forms of generation?

    (a)  Financial Institutions have shown themselves willing to invest in all forms of generation. They have been keen to gain a proper understanding of the market structure and of the risks that might exist and the respective allocation of these risks to relevant parties.

    (b)  A wide spectrum of these institutions has substantial investments in a range of utilities that have nuclear power as a part of their generation portfolios in Europe and the US and there is no evidence that they have demanded different rates of return for the nuclear component of these investments. For example, 35.2% of British Energy debt and equity is held by these investors.

What is the attitude of financial institutions to the risks involved in nuclear new build and the scale of the investment required? How does this compare with attitudes towards investment in CCGT and renewables?

    (a)  Financial Institutions have shown themselves willing to support nuclear new build around the world. Most recently, in Finland, 75% (

    2.25 billion) of the capital for the build of a new nuclear station at Olkiluoto has been provided from the capital markets with only 25% being contributed by the plant owners. This financing has been handled by a consortium of Scandinavian, Continental European and US banks.

    (b)  In other markets, the question of private financing for nuclear new build is less well advanced. However, the reported rapid progress of efforts by privately-held utilities in the US to obtain site and design permits suggests that these companies believe that access to the requisite capital will not be an insurmountable obstacle.

    (c)  There has been some public debate in the UK about the financing issues surrounding new nuclear—and the relative merits of different technology investments. A senior investment banker has stated recently that "From the financial market's perspective, this framework must allow transparent measurement of risk-return profiles—i.e the markets will bear measurable risks against acceptable return levels. If so, the market believes such investment propositions offer significant liquidity for new investment, particularly in a UK environment increasingly experienced in public-private partnership."

    (d)  For the UK to reach this point requires clarity over longer term policy. It is noteworthy that the only sector today where there is substantial capital market funding of new build efforts is the renewables sector where investors have been able to take comfort from the relative surety of the Renewables Obligation scheme to justify the risk-to-return trade off to their capital committees. Otherwise the case for any investment has been hampered by regulatory uncertainty around environmental legislation, price volatility in the oil, gas and carbon markets and the increasingly illiquid and short-term nature of the wholesale electricity market.

How much Government financial support would be required to facilitate private sector investment in nuclear new build? How would such support be provided? How compatible is such support with liberalised energy markets?

    (a)  It is not clear what—if any—direct financial support will be needed from the Government in order for private sector investment in new build to take place. Before it is possible to form a view on this question, it is necessary to assess the options to address particular classes of risk and to identify the extent that the private sector is able to take these risks without Government financial support. The major risk components where greater clarity is needed are:

      —  The approach to making provision for the costs of decomissioning the station and handling spent fuel and other arisings.

      —  The approach and timetable for regulatory and planning review of any new build proposals.

      —  The scale of any new build efforts to be undertaken.

      —  The market arrangements under which the power will be sold, including the future of European arrangements such as the later phases of the Emissions Trading Scheme.

    (b)  In the US, the government has concluded that a programme of incentives are required to address the potential first-mover disadvantages associated with the early stages of a wider new build effort. This has led to joint funding of the design and site reviews by the public and private sector, insurance against regulatory delays, continuation of the Price-Anderson insurance arrangements and has also resulted in tax incentives that will be available to the first plants to be commissioned. It is not clear whether any of these will be appropriate in the UK context. However, there is a lot of evidence that these can be made to work against the backdrop of a liberalised and competitive energy market. For example, the UK has incentives for renewables, for energy efficiency and now for the development of new "clean coal" demonstration projects and has been able to accommodate these in a deregulated market.

What impact would a major programme of investment in nuclear have on investment in renewables and energy efficiency?

    (a)  Very little because they service different parts of the supply sector, and all carbon free, "indigenous" technologies will be needed in the future if the Government's environment and security-of-supply needs are to be met. The Government has well established initiatives to promote the renewables sector and energy efficiency, with excellent financial support mechanisms, and a clear signal that these programmes will continue for long periods of time.

C.  STRATEGIC BENEFITS

4.   If nuclear new build requires Government financial support, on what basis would such support be justified? What public good(s) would it deliver?

  To what extent and over what timeframe would nuclear new build reduce carbon emissions?

    (a)  Nuclear power was originally developed to deliver large quantities of baseload electricity. Because it is essentially emissions free, it is fair to say that this form of generation has contributed hugely to the UK's climate change and air quality targets over the last 30 years or so, and it will continue to do so for some time to come.


    (b)  The scale of contribution by the nuclear power sector to the UK's climate change targets is shown in Figure 5. The contribution can be considered in three phases: the climate change benefits associated with the existing nuclear plants over their original stated lifetime; the benefits associated with life extension of six of the seven AGR stations already declared, and the potential life extension of the seventh AGR at Dungeness B; and the potential benefits of a new build programme phased in over an assumed 15 year period to the level outlined in the Inquiry terms of Reference (ie "nuclear new build is used to refer to a programme of at least eight AP1000 reactors, or equivalent").

    (c)  Figure 5 shows the carbon dioxide contribution to the UK's Kyoto target of 12.5% greenhouse gas (GHG) reduction on 1990 levels—this contribution was estimated originally at about 8% of the 12.5% GHG reduction. Nuclear power today arguably makes the biggest contribution to this target. In 2004, 73.7 TWh of nuclear generation avoided the emission of about 49 MtCO2 that would otherwise been emitted by the prevailing fossil fuel mix. The scale of contribution by the nuclear industry is about the same as the 8% reduction originally estimated, which is a major contribution that will have to be found elsewhere if the nuclear component to the generation mix disappears. To put this into context, about three quarters of all the cars on the roads would have to be removed to get the same climate change savings as those associated with nuclear generation.

To what extent would nuclear new build contribute to security-of-supply (ie keeping the lights on)?

    (a)  Security-of-supply (SOS) can, for example, refer to import dependence of fossil fuels or reserve margin for electricity generation, or both. Both of these aspects of SOS will provide challenges to the UK's energy system.

    (b)  Nuclear power can be considered "indigenous" and as such can contribute to UK SOS. It is instructive to sum the indigenous components of the UK generation mix: indigenous coal and gas, nuclear and renewables.

    (c)  Figure 6 shows that using the government's own projections the indigenous contribution to the UK's electricity supply will decline from almost 100% in 1990 to about 50% by 2020, primarily due to an increasing reliance on imported gas. These figures assume a successful Renewables Obligation—40 TWh by 2010 and 58 TWh thereafter, that energy efficiency measures will suppress energy demand, and the successful declared life extension programmes of the AGR nuclear fleet. A small extension in time to 2030 sees indigenous supply decline further to about 25%.

    (d)  It is not clear what constitutes an acceptable SOS for the UK because the country has not been in this position before. The issue is made more complex because the UK has relatively little connectivity with other European countries which would serve to make SOS less of an issue than it is.

    (e)  Figure 6 also shows that new nuclear build to the level indicated in this Inquiry will increase SOS markedly—from about 25% indigenous to about 45%, and this capacity will be available to the UK for most of the 21 century.

    (f)  It is often stated that the UK has benefited from a diverse set of energy sources. However, this diversity will diminish if, as currently projected, coal and nuclear are replaced by gas, leading to a more vulnerable electricity sector.

    (g)  In the same way as nuclear generation avoids the emissions of harmful pollutants, it also avoids the consumption of finite fossil fuel reserves that would have been used for power generation, particularly gas. It could be argued that British Energy's eight nuclear plants avoided the consumption of about 13 billion cubic meters of gas, of which about 1 billion cubic metres would have been imports, in 2003. To put this in context, this saving is equivalent to about 38% of the domestic use of gas in the UK.

    (h)  Figure 7 shows the total projected avoided gas consumption because of nuclear generation over the next two decades, the total value of this resource, and the level of imports involved. Clearly this helps the UK SOS situation and is of significant benefit to the UK economy.

    (i)  The reserve margin is the amount by which the total installed capacity exceeds peak demand. Experience suggests that a value in excess of 20% is needed to support a modern economy. The Royal Academy of Engineering, in their Submission to the European Commission Inquiry into the UK State Aid Case for British Energy [14], recognized the importance of nuclear power to the reserve margin, particularly as their analysis based suggested a decline in this important indicator over the next decade or so under a number of plausible scenarios. Their recommendation was that it was important the UK maintain the nuclear option if it was to meet not only the reserve margin challenge but for all aspects of SOS.

    (j)  Figure 8 compares the current UK generation mix with some those of other EU countries. Italy would appear to be the least secure because it relies heavily on gas and oil generation. However, the UK also relies heavily on gas generation at this time and as shown in the figure will become overwhelmingly more so by 2020, and as indicated elsewhere in this submission, almost all of this will be imported. This could place the UK at a disadvantage when compared to our main European competitors Germany and France.

Is nuclear new build compatible with the Government's aims on security and terrorism both within the UK and worldwide?

    (a)  Yes, if the plant, processes and systems are designed and operated well. Nuclear facilities and their related operations are already very well protected through robust construction and a recognised responsibility to maintain a high security culture at operator and national levels. New plant will naturally have enhanced security protection through improved design.

    (b)  However, it is also recognised that confidence in the industry needs be improved and this can be achieved by informing the public of our commitment to enhancing security in cooperation with the appropriate authorities.

    (c)  With its long established civil nuclear programme the UK has a tradition of participating in international co-operation programmes. The UK can continue to do this for the foreseeable future but only in the context of a declining role as the existing plants are closed. A new build programme would help shape the way in which the UK responds to the threats to security and terrorism in this important area, both at the national and international arenas.

5.   In respect of these issues [Q 4], how does the nuclear option compare with a major programme of investment in renewables, microgeneration, and energy efficiency? How compatible are the various options with each other and with the strategy set out in the Energy White Paper?

    (a)  A new nuclear build programme would provide more certainty than the other options currently available in terms of delivering climate change (CC), security-of-supply (SOS) and electricity price stability benefits to the UK. In reality it is not a case of a preference for one option over the others—all these technologies will be needed to address the UK's CC and SOS needs over the long term.

    (b)  It is fair to say that the nuclear option requires greater security to counter terrorist risks. However, such risks can be minimised through strict adherence to the Government's guidelines in these areas, maintaining a culture of vigilance and the development of robust security processes.

    (c)  The Energy White Paper placed emphasis on policies and measures for the deployment of renewables (including micro -generation technologies) and the encouragement of energy efficiency; it left the nuclear option open, to await the success or otherwise of this strategy. Developments since publication of the White Paper suggest that the nuclear option should now be given serious consideration.

D.  OTHER ISSUES

6.   How carbon-free is nuclear energy? What level of carbon emissions would be associated with (a) construction and (b) operation of a new nuclear power station? How carbon-intensive is the mining and processing of uranium ore?

    (a)  An independent full life cycle analysis has been carried out on British Energy's nuclear AGR plant at Torness by the consultants AEA Technology using a methodology which will shortly be adopted by the International Standards Organisation. Figure 9 summarises the carbon emissions associated with each stage of the process, with emissions associated with the extraction of the fuel the biggest contributor of all the stages. Total life-cycle emission are just 5 g/kWh, a little higher than the 3.3 g/kWh average value reported by Vattenfall in a similar analysis on their BWR and three PWR power plants.

    (b)  Figure 10 compares the total carbon emissions from the life-cycle for Torness with those associated with the operational component for coal and gas technologies alone. It is clear from this comparison that for all intents and purposes nuclear generation can be considered carbon dioxide free.

    (c)  A similar analysis can be conducted for sulphur and nitrogen oxides, key components of photochemical air pollution. Once again, nuclear generation is essentially emissions free when compared to coal and gas generation.

7.   Should nuclear new build be conditional on the development of scientifically and publicly acceptable solutions to the problems of managing nuclear waste, as recommended in 2000 by the RCEP?

    (a)  There have been a number of important initiatives in the last few years that will help to resolve the legacy and ongoing waste streams from the nuclear sector, most prominent of which has been the setting up of Committee on Radioactive Waste Management (CoRWM) and the Nuclear Decommissioning Authority (NDA).

    (b)  CoRWM will make concrete proposals for dealing with the waste when it reports to Government in July 2006. The Government then needs to establish the policy framework and implementation plan to deliver its preferred solution to this issue for the industry and country. New nuclear build can be progressed in parallel with the siting and building of the long term repository.

    (c)  Recent work has established that the amount of waste from a new build programme on the scale proposed will add very little to the legacy waste that in any event needs to be dealt with. The facility built to deal with the legacy waste can be designed to accommodate the extra waste from a new build programme.

    (d)  Lessons learned from other countries—Finland, USA and Sweden in particular—suggest there are no technical barriers to dealing with the waste issue. Rather, it requires political will and an honest and transparent dialogue with the public in general and the local community where the facility will be located in particular.

    (e)  The 1976 RCEP Report expressed the concern that there was a lack of work being done at that time by the Government and by the nuclear industry on the treatment and disposal of nuclear waste. The Report recommended:

    "There should be no commitment to a large programme of nuclear fission power until it has been demonstrated beyond reasonable doubt that a method exists to ensure the safe containment of long-lived highly radioactive waste for the indefinite future".

Lord Flowers, 1976 RCEP Report [16]

    International developments since the Report was published have demonstrated there are viable solutions to this problem, as recognised earlier this year by Lord Flowers:

    ". . . a method to ensure safe disposal for the indefinite future—namely, underground storage—has been demonstrated beyond reasonable doubt in other countries, especially Finland."

Lord Flowers speaking in House of Lords, January 2005 [16]

    (f)  In light of the comments (b)-(e) we believe new nuclear build can proceed on the scale proposed in this Inquiry.
