Nuclear Reactors

Baroness Trumpington Excerpts

Thursday 7th July 2011 Lords Chamber

[Lord Marland]

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.

[Baroness Trumpington]

My Lords, please forgive my ignorance, but what is thorium?

[Lord Marland]

If only my O-level science teacher could see me now. I am very grateful to the noble Baroness for that question because I have learnt a lot about thorium recently. For those who wish to know, it is named after the Norse god Thor. It comes out of monazite sands, which are largely found in India and Norway, and is generated by a sifting process. The noble Baroness will be pleased to know that it is dimorphic, which I am happy to explain means that it changes from face-centred to body-centred. However, other noble Lords are far more qualified than me to inform us about thorium. All I would say is that it requires two neutrons to process it rather than one. The noble Baroness can find all sorts of other facts in Wikipedia, as, indeed, did I.
