Nuclear Research and Technology (Science and Technology Committee Report) — House of Lords, 2017-10-17
Topic: Energy
Julian Charles Roland Hunt (Labour, Centre-left): My Lords, this is an important debate as Parliament once again considers nuclear research and technology and how it should be organised in future. I thank the noble Earl, Lord Selborne, for chairing our committee very well. I declare an interest, having worked in the past on research and advice in civil nuclear fission associated with industry in the CEGB, the UKAEA and EDF Energy, and more recently on fusion, first with the Culham fusion laboratory and then with the commercial Tokamak Energy As the report by the House of Lords committee concludes, the UK’s planning and co-ordination of civil nuclear fission power stations has not led to investment in fission construction—really, from the 1970s onwards. In his evidence to the committee, a director of EDF Energy, Mr Xavier Mamo, was asked how they did things in France. If you look at paragraph 29, you will see his very complete description. He described the strategic governance of the nuclear fission industry by the French Government and said that there was high-level political participation in the committee. Over 50 years, nuclear-powered electricity expanded to 80% of the total. A strong feature was the involvement of top engineers and scientists—for example, École des Mines—with access to the highest levels of government By contrast, the UK has had a number of different technical bodies, listed on page 9 of our report, for its research, technology and regulatory tasks, with different sources of funding. Our committee was not impressed by the current co-ordinating body of NIRAB, set up in 2014. At points 9 and 10 of the Government’s response, they announced the creation of a successor to NIRAB, but they could not find time to give it a new name. I gather that the name is likely to stay the same. Surprisingly, the new body is apparently only for nuclear fission; there is no reference to fusion research and technology, which will play a significant role in future energy systems. Is the new NIRAB membership restricted to non-commercial bodies, even in key areas of expertise, which would then be omitted? Can the Minister clarify that in his response? This high-level independent body should review and promote the appropriate public and private nuclear systems to be considered. It should take a strong role in participating in international programmes such as the fourth generation system, and international bodies such as the IAEA and the future form of and connectivity with Euratom. This body should also involve the UK’s two significant fusion programmes. One is run by the UKAEA at the Culham laboratory, which also works in collaboration with Euratom. The second, totally unmentioned in all government statements, is the very large and significant commercial Tokamak Energy system. I know from other parts of my life that you can do some extraordinary work and the Minister can announce it in the House of Commons, but then there is no reference in any public document to this commercial activity. Sometimes you feel that the parties are swapping on the other side of the House. This company, Tokamak Energy, whose publications are now the most cited of any fusion project in the world, is in Britain, in Didcot. Is it referenced? No, it is not An important part of the Government’s response is their outline proposal that the UK should start soon on a programme of constructing small modular reactors, such as the Rolls-Royce proposal for constructing about 10 400-megawatt nuclear fission devices, pressurised water reactors, which could be operational in about five years. Sites have been specified and identified, some of which are in critical parts of the UK, where the northern powerhouse could participate. The UK’s construction of submarines, which is where this technology was developed, involved stressful conditions, ensuring that these reactors will be very reliable. I understand that already some overseas countries are expressing interest in buying UK-proposed SMRs The new NIRAB should also address the long-term challenge of developing nuclear energy fusion, so that there will be no need for mining uranium or processing past and present nuclear waste. It will take hundreds of years even to deal with that waste, but not the tens of thousands of years into the future when we have nuclear waste either in concrete underground or in other processes. Such very long-term issues need to be discussed by the new body, and it needs to bring in all the people and organisations who can contribute.
