My Lords, I had rather a nice time working with the Liberal Democrats in the Cameron Government, when, in an enlightened way, they were strongly in favour of nuclear power. It appears that they chop and change from time to time, but those were the days.
Before I speak further, my noble friend Lord Trenchard has reminded me that I should have made it absolutely clear that I have an indirect interest to declare, in that I advise Mitsubishi Electric, which is concerned with the power sector and indirectly therefore with nuclear
construction. I suppose that I also have a sort of interest in the sense that I was Secretary of State 40 years ago and tried to build nine new reactors, of which only one, Sizewell B, was ever built. I think that I am allowed to reflect to this Committee that things would be much nicer for us if we had got the other eight built as well. They were all low-carbon and would have helped greatly in the present crisis, but that is all history.
On these amendments, it is absolutely true, as the noble Lord, Lord Oates, observed, that the radioactive waste issue requires careful handling and examination, and it must be addressed fully and with all the knowledge that we can bring to bear to establish and meet the many understandable concerns about it.
As for value for money, we will come to that in the next amendment. Of course, there are enormous difficulties in defining what value for what money, but we can debate that in more detail in a moment.
What is not true is to imply that there has been no technical solution to the absolutely safe—nothing is 100% but it is highly safe—burying of high-radioactivity nuclear waste for thousands of years. It is certainly more than 40 years since the late Walter Marshall explained to me that vitrification and burial two or three miles down in a stable geological formation was very nearly foolproof. There was a faint possibility of corrosion of the glass vitrification case around the radioactive material, but otherwise it would be safe for hundreds of thousands of years. He added, rather cynically, that if before then people wanted to dig it up and eat the glass, they may have more problems than radioactive waste. The vitrification option is there; it can be done.
In the great debate going on in America about the Yucca Mountain development as a waste disposal centre, I noticed that the statistics produced—I have the precise figure here—say that all but one in every 10,000 waste packages going into the repository, if it is built, would be secure for more than 150,000 years. So we are talking about the most minute dangers. The danger is there, but it is minute, and has to be weighed against all the other problems—we will come to value in a moment—of abandoning an area of low-carbon electricity which will be reliable, will stop a great deal of the suffering that we have today, and will be not only a stepping-stone to but a crucial adjunct and back-up of the renewable and clean energies that we all want to see dominate when conditions allow.
