To ask Her Majesty’s Government what research they have undertaken into, and what assessment they have made of, the use of thorium in nuclear reactors.

My Lords, the Government are in the process of assessing the benefits of next-generation reactor technologies, including thorium, for the longer term, and the Secretary of State has asked the National Nuclear Laboratory to prepare a report. A previous NNL assessment of a number of claims made by proponents of thorium fuel concluded that while the theoretical science is reasonably sound, the risks and resources involved in achieving commercial deployment are significant.

I am grateful to the noble Lord for his response. It is helpful, and I certainly welcome the fact that the Government are taking this more seriously. He will understand that despite greater acceptance of nuclear power there remain concerns about nuclear waste, both because of its potential military or terrorist use and because of the costs and difficulties of long-term storage—as he and I have discussed on many occasions—as it cannot be disposed of. Liquid fluoride thorium reactors generate no high-level waste material, and can reduce existing stockpiles of waste. Given that, while I welcome the Government’s assessment and the expected report, is there more that the Government can do to test the technology? Also, on a wider basis, have the Minister and his department given any thought to whether this is a technology for nuclear power that could be safely developed in all parts of the world?

I am grateful for the noble Baroness’s question. The reality is that we have waste, so it will not improve the situation with regard to nuclear waste. This Government are very concentrated at the moment on recovering from 25 years of no nuclear activity with what we have. We have to concentrate on the reactors that are available, which we have had approval for, in order to get our next-generation nuclear power off the ground. We know fully that thorium reactors will take 10 to 15 years to develop. There is a high cost in that development and, at the moment, I would not put it as a priority unless the research report that comes out at the end of this summer advises us otherwise.
