Nuclear Research and Technology (Science and Technology Committee Report) — House of Lords, 2017-10-17
Topic: Energy
Alec Broers (Crossbench, Unknown): My Lords, I congratulate the noble Earl, Lord Selborne, both on his excellent opening speech, which so well reflected the findings of the Select Committee, and on his characteristically expert chairing of this inquiry, as mentioned by the noble Lord, Lord Oxburgh I shall restrict myself to one request this evening in the hope that, should it be granted, we would be in a better position to realise what is proposed for power generation in the Clean Growth Strategy, published last week. This strategy contains some good news on renewables and points out that one way to see power emissions fall by 80% by 2032 is to grow renewables and nuclear to over 80% of electricity generation. I agree with that approach. My request is that a detailed and quantitative road map also be developed that shows the possible ways for delivering this combination of renewables and nuclear and, indeed, other alternatives. This road map can use as a starting point the Nuclear Energy Research and Development Roadmap, developed by Sir John Beddington’s ad hoc committee in 2013, and should become an essential part of the cost of energy review to be carried out by Professor Dieter Helm. The Clean Growth Strategy contains what are called decision pathways, which are valuable but far from complete in giving specific targets for delivery either in energy supply or usage. They do not describe how and when the many different technologies will be introduced and at what price the energy will be delivered. Nor do they set quantitative targets, or schedules for the various methods for reducing consumption. The type of road map that I am seeking would allow progress to be monitored across the full spectrum of energy supply and demand and include alternative pathways that could be followed should technologies fail to meet their predicted performance levels or schedules. I have not been able to find such information anywhere in the supplementary documents referred to in the Clean Growth Strategy. So, at the moment we seem to be proceeding with a hope and a prayer that what is required will be delivered when it is needed and we can only despair when schedules slip and costs overrun, as they inevitably will with the complex factors that comprise our overall energy system These factors include everything from the price of gas and the potential of fracking to the long-range consideration of when fusion energy will become practicable. One cannot predict with any precision the progress gained through investment in R&D, but it is none the less necessary to make predictions so that one has a scale against which to measure actual progress. Reference to the road map will indicate whether it is necessary to change direction as new ideas and unforeseen problems appear and show the options that are open for change As I have said, the Clean Growth Strategy states that renewables and nuclear together may have to increase by 80% by 2032. There are many options open to back up intermittent renewables but the best option appears to be nuclear fission, and this is what is put forward in the Clean Growth Strategy. The pair of EPR reactors at Hinkley Point are to play a major role in maintaining our nuclear capability. However, there are likely to be continuing delays and cost overruns before they are operating. The two similar EPRs that the Chinese are building at Taishan are experiencing further delays, as are the reactors at Flamanville in France. The first Taishan reactor is now scheduled to go online in 2018, four years behind schedule, and the first at Flamanville in the middle of 2018, about six years behind schedule The road map I am asking for should include all of the many alternative energy sources, but it is especially important that it includes small modular reactors, which have several advantages that make them ideal, as mentioned by many speakers, for backing up intermittent renewables, as advocated, for example, by NuScale for wind energy. The US company, NuScale, was the first to have its design accepted for evaluation by the US Nuclear Regulatory Commission in March of this year. The NRC will take 40 months to review and issue a design certificate. When that is done, it is expected that the first SMR will be operating in conjunction with a wind farm in Idaho in the early 2020s. SMRs will be the smallest commercial reactors, giving them great flexibility and low cost. It is claimed that they can be too small to melt down, so they are safe. Worldwide there are about 50 SMR designs under development and it is hoped to reduce the capital cost to about $2,000 per kilowatt, which is about the same as for the EPRs If we are to enter the SMR market, we had better get on with it. Please Minister, may we have a comprehensive road map so that we may better understand how and when to employ the different types of nuclear reactors?
