My Lords, by now the Minister will probably have got the message that this House thinks Euratom is pretty important for the reasons given. I shall not repeat them, but they are very sound. Indeed, sitting yesterday as a member of the Science and Technology Committee, under the chairmanship of the noble Earl, Lord Selborne, we received evidence on nuclear matters. We raised Euratom. There certainly was dismay among our witnesses at the prospect of the UK leaving it.
Nuclear energy will play an important part in the energy plans of the present Government and, I suspect, any Government we are likely to have in the near future. That said, as my noble friend Lord Krebs pointed out, our expenditure on nuclear R&D is simply derisory by international standards. For that reason, we get enormous benefit from our membership of Euratom—proportionately more than almost any other member.
Probably the most important point to recognise is that Euratom governs not just non-proliferation, but the movement of nuclear materials and, above all, nuclear IP. If Brexit goes ahead on the timetable we have at the moment and nothing is put in place effectively to give us continuing membership of Euratom by some means or other, that occurrence would come right in the middle of the build at Hinkley. It is not impossible that Hinkley would come to a serious and grinding halt unless the Government somehow manage a better arrangement for the future.
