Select Committee on Public Accounts Minutes of Evidence


Examination of Witnesses (Questions 20-39)

DR IAN ROXBURGH, MR JAMES MORSE AND MR MARK HIGSON

25 FEBRUARY 2008

  Q20  Chairman: The people who bid for Sellafield or get the contract will be covered by this, will they?

  Dr Roxburgh: They will be, yes. Further in the contract, by the time they have been in place for 18 months, they must have scrubbed through the lifetime plan numbers and given us their own view on how they can again be improved.

  Q21  Chairman: It says here at paragraph 4.18, "At Sellafield, of the site's eighty operating units, only seven identified that they had been able to build efficiency savings made in 2006-2007 into their 2007 lifetime plan submissions". That does not sound very impressive.

  Dr Roxburgh: I will turn to my colleague in a moment, but one of the things we did from day one was to introduce an efficiency fee target for the sites, albeit the PSA target did not require us to do that until year two of our life. We have to date saved over £300 million and a significant chunk of that has actually come from Sellafield.

  Mr Morse: We certainly recognise the challenge in those numbers from NAO and agree with them. There are two real explanations. One is that a number of those initiatives were one-off projects within that year. That really speaks to a longer term solution. Currently our efficiencies and our costs are on a one year ahead basis. We would like to move to something that is three to five years ahead. That is not necessarily an issue about funding but more about programme management philosophy. We see the water industry under their own programmes where they have a five year target for efficiency savings; ours are still on a one year basis. When we can get to the longer horizon then we will see those being built in by instinct by the contractors. We certainly recognise the challenge there.

  Q22  Chairman: Mr Higson, we had this White Paper last month from HM Government, Meeting the Energy Challenge, and were told in this that the energy companies—we are hoping we are going to get nuclear power stations built—will be able to meet the full cost of decommissioning. Given the answers that I have received today about the existing estimate and its unreliability, can we be at all confident that these energy companies can possibly be able to meet these costs?

  Mr Higson: I think an important point to bear in mind about the £73 billion costs estimated by the NDA is that £16 billion relate to the decommissioning of nuclear reactors. That is £16 billion on 11 sites and 26 reactors. A large part of the variation and a large part of the amount of £73 billion relates to facilities which are legacy facilities and will have no part in the future of nuclear power. For example, the silo which is featured on the front cover of the NAO Report until relatively recently there was no plan for actually cleaning it up and that is something that the NDA has brought to the party. The second point I would like to make is that going forward there has to be a clear waste management and decommissioning plan, a plan approved by the secretary of state before the power station and can operate. Modern reactors are designed with decommissioning in mind. I think the further point is that there is actually real experience internationally now accumulating on the actual cost of decommissioning reactors. If we put that together with a mechanism for ensuring that the costs of decommissioning are scrutinised regularly, there will be quinquennial reviews and there will be a duty on the company to ensure that the decommissioning fund is adequate to cover the costs, if all of those things are put together that is a very reasonable package.

  Q23  Chairman: You can say, on behalf of Parliament, hand on heart, "I give a commitment that the energy companies will be able to meet the full costs of decommissioning new nuclear power stations". If you want to plead the Fifth Amendment I quite understand.

  Mr Higson: The Government's proposals are to put in place everything that is reasonable to ensure the tax payer does not pick up the cost.

  Q24  Chairman: I am not sure that that is an answer to the question.

  Mr Higson: You cannot get an absolute assurance.

  Q25  Chairman: I put it to you that we have absolutely no assurance whatsoever given the escalating costs that we have been talking about for the last 15 minutes. You have virtually plucked a figure out of the sky and you cannot say with any degree of certainty that the energy companies will be able to meet the costs. You will long be gone and so will I but it is very likely that some future Public Accounts Committee will be discussing how the tax payers will be picking up the tab once again. That is the truth.

  Mr Higson: We have put in place every possible protection.

  Chairman: I am sure you have put in every possible protection but you will have to be a lot more convincing. I will let my colleagues carry on and maybe you can do better. Angela Browning?

  Q26  Angela Browning: To begin with, Mr Higson, in the last Parliament this Committee took an evidence session on the subject of alternative energy and in the course of that discussion I very clearly remember asking about the possibility of replacing our nuclear reactors with new ones. At that stage everything had come to a halt because we were approaching an election and this was a very hot topic about whether there was going to be a commitment to proceed with new build. Can I just ask you, how much has that political decision to delay making such an announcement affected the decommissioning of the existing nuclear power stations?

  Mr Higson: I do not see there is a connection.

  Q27  Angela Browning: The reason I am asking is because whether we decided to replace or not one would have thought, knowing particularly for example that the Magnox reactors were getting to the end of their natural life, there was a very timescale—it was even debated in precise terms of years in this Committee and that would have been three or four years ago—and I have difficulty in understanding why you are having such difficulty in identifying the costs associated with decommissioning and giving clearer answers. You have had a lot of time to get all these ducks in a row, have you not?

  Mr Higson: I am not sure that we are having difficulty with the costs of decommissioning. We set up a process, which will ensure that they are transparent and subject to public scrutiny, in the consultation document published earlier this year. We have actually set out our estimates of what the costs of decommissioning nuclear power stations will be. We have a process going forward to ensure that they are subject to the best possibly public scrutiny. I think that is a very substantial protection.

  Q28  Angela Browning: Why are we not doing as well as other countries? America have decommissioned seven of theirs; Germany are making good progress. If we had all this forward planning and our costs were much better organised, as you are saying they were, why are we behind other countries?

  Mr Higson: I am talking here about estimating the cost of new nuclear power stations. The issue of how quickly we decommission the Magnox stations is an issue about the priorities and the overall budget for the NDA.

  Q29  Angela Browning: Is it possible that these old Magnox stations, the sites that they are on, would be used for any new build?

  Mr Higson: As we said in the nuclear White Paper we do expect that focus from potential new nuclear operators to be on existing nuclear sites, so yes.

  Q30  Angela Browning: How does that read across and impact on the decommissioning of the old reactor that is on site then?

  Mr Higson: The decommissioning needs to proceed.

  Q31  Angela Browning: If you are building on one site and you decommissioning on the site is there nothing to take into account in terms of costs et cetera?

  Mr Higson: Those would be issues that the NDA will need to consider most carefully in the coming weeks and months and it will need to take a view on what is the right way of making its sites available.

  Q32  Angela Browning: If you were to put a new reactor on a site of an old Magnox, let us just take Hinkley Point which I have visited a couple of times and I am looking at figure 15 on page 33 where there has obviously been some difficult with the Ponds which has increased the cost over the expected budget. What would be the situation if you were to put a new reactor onto the Hinkley site? Would that affect the costs and the project of decommissioning in some way?

  Mr Higson: I will answer as much as I can and then I will turn to Dr Roxburgh. My understanding is that the site that is available for potential construction of a new nuclear power station is actually in large measure owned by British Energy. Dr Roxburgh might want to comment on the impact that a nearby construction site might have on the costs of decommissioning.

  Q33  Angela Browning: Before Dr Roxburgh answers, could I just come back to the point I made about the comparison between the UK and other countries who clearly have been getting on with this. Has there been much contact between the UK Government and other countries knowing this was a major project we needed to embark on?

  Dr Roxburgh: There are similar reactors in Japan and there are some early reactors in France with similar characteristics to our Magnox fleet. In both those countries they have a programme which is ahead of ours. The site I went to in Japan was looking to decommission over a period of 17 years and there is a policy in France that their first five reactors coming off line hopefully would be back to grass within, say, 25. The issue in the United Kingdom is not a lack of will, it is an issue of technicality. Within our Magnox fleet we have something approaching 58,000 tons of graphite which is contaminated with carbon-14. At the moment we have no disposition to that, in other words if we take it out of the reactor where it is quite safe and properly contained we have nowhere else to put it without building other concrete nuclear stores. That is at additional cost and extra dose for the workforce to take it out, put it in those new stores and in due course you will want to take it out of those stores and put it into a repository. I am optimistic that once it is clear as to exactly when and where we are to have a deep geological repository these issues can be revisited. Indeed we make the point in out approved strategy that we can only make the business plan if indeed we can find this final disposition.

  Q34  Angela Browning: I wonder if I could just bring you onto page 33 and come back to this chart we have here. If we look at where efficiency fees have been paid as a percentage of the budgeted costs which the Chairman referred to earlier on, can you just give us some broader indication of why there is such a differential between the top and the bottom on that graph?

  Mr Morse: In one sense it represents the different attitude on those sites towards the task in hand.

  Q35  Angela Browning: Could you explain what you mean by "attitude"?

  Mr Morse: Culture, organisation, structure, the number of sites still organised in a very disciplined way.

  Q36  Angela Browning: Please do not tell me we have nuclear power stations on sites that are not disciplined in the way they deal with things. You surely did not mean that.

  Mr Morse: No, I did not. What I meant is in functional organisation. The best performing sites are kind of project types, so a multi-discipline team addressing the single objective. That is in fair measure of what we have seen across the sites. Of course the measure of efficiencies against our yearly targets has earned value which is an estimate of the work to be done in that year and then the cost of completing that work. Again some sites are more innovative and work more effectively than others do. They are all coming up the curtain; that is part of the process of having the lifetime plan that we get compliance and we get comparison between sites; comparison drives efficiency, aided of course by our competition principle.

  Q37  Angela Browning: Can I just ask you about Sellafield? I see that is down at the bottom here. It is some years since I have visited Sellafield—I have been there twice in the past—and the last time I was there my understanding was that the facility that we have there had the potential for re-processing other countries' nuclear waste and storing it longer term. Can you enlighten us as to whether that is still the case and what the possible financial impact of that storage is? In other words, is that still being paid for by the countries of origin?

  Mr Morse: You are referring to the THORP oxide reprocessing plant which has contracts running for probably about another five or six years, depending on its performance. The contracts that were set up in the late 1980s and early 1990s that funded THORP and funded that reprocessing are still flowing through.

  Q38  Angela Browning: The cost of cleaning that facility up, is that calculated and recovered in the costs that we charge to other countries to reprocess or is this an unknown quantity down the track for the Sellafield site?

  Mr Morse: THORP is one of the most modern facilities across the NDA's 19 sites and as such was built with decommissioning in mind. There is an estimate for that decommissioning and that estimate has been revised in the previous lifetime plan submission. As to the recovery and the accountancy around the decommissioning estimate I would have to take some further advice on that.

  Q39  Angela Browning: The reason I am asking is that there seems to be a marked difference between our approach say to THORP which is clearly a very important commercial operation and in calculating and recovering in our estimates the cost of the contamination over a long period of time. You seem to have been quite clued up on doing that but perhaps not in general about the nuclear sites themselves.

  Mr Morse: I am fairly sure that the THORP contracts include an element of the decommissioning cost.
