It is actually a matter of millennia, if you want to put nuclear into its proper context. I do not dispute that the pendulum of regulatory approaches to nuclear swings. I have visited Oak Ridge, the home of nuclear fission research, where nuclear gases used to be vented into the woods because people did not perceive it to be a risk—indeed, there is something to be said for the view that that was not a
very risky activity. We have swung back towards very tight regulation for good reason, but that is not to say that that has to be set in stone and that our approach today is right—there is a constantly shifting understanding. I said that background radiation is natural to make the basic point that we as human beings have evolved in a radioactive environment. People are not always aware of that.
This is about getting back to the basics and having another look at the physics of nuclear, so that we can perhaps defuse some of the fears. There is probably no riskier way of storing nuclear waste—if there is indeed a large risk—than the way we use today. I am grateful to the noble Lord, Lord Avebury, for pointing out that we seem to be speaking as if there is no waste and that we are suddenly creating waste to put into a depository. The waste exists and it sits around the country, although it is correct to say that a large proportion sits in Sellafield. We need to find a solution, but that is not to say that this is the greatest risk that man has ever faced. The risk is manageable and engineered and we should see it in that context.
I will not detain the Committee any longer. I am grateful for the debate. I reiterate my request from our last debate that we should begin to have a national public conversation about nuclear and the risks involved. As other noble Lords have said, the issue has to be seen in the context of the much broader environmental risks that we face. There is an inherent logic behind the regulations. This is a nationally significant project and, although we do not wish local involvement to be excluded, we need to get the balance right, so we support the regulations.
