My Lords, this issue is not quite as simple as the noble Lord, Lord Hunt, claimed. I too was present at the briefing referred to
by the noble Lord, Lord Warner, given by the Nuclear Industry Association and EDF, which was very valuable.
The issue is not as simple as the noble Lord, Lord Hunt, said—namely, that Euratom is the most marvellous institution and we have to remain a member of it or continue to apply standards equivalent to those which have been developed by it. I recall that EDF explained that the international standards are set by the IAEA, and that it is absolutely necessary that before exit, other than by virtue of a transition or implementation period, which of course applies more generally to the EU, in order to exit from Euratom and continue to be able to trade in nuclear equipment and fuel, we need an IAEA-accredited—not Euratom—safeguards regime. We need nuclear co-operation agreements with four countries: the United States, Canada, Australia and Japan, a nuclear agreement with the European Union and an export licence regime. Euratom’s nuclear safeguards regime concentrates heavily on verifications, whereas the IAEA places more emphasis on process, operations and compliance with international standards.
The noble Lord referred to isotopes. It is essential to ensure a secure and consistent supply of radioisotopes. Molybdenum-99, for example, has a half-life of 66 hours, similar to human organs, and therefore cannot afford to be delayed by customs at ports and airports. There can be no delay at all. We obtain about 60% of our radioisotopes for medical use from the EU, to which the noble Lord referred, but we obtain 40% of our isotopes from non-EU countries, principally South Africa, which the noble Lord did not refer to. I understand that the procedures for importing both those from the EU, which come through the Channel Tunnel without, obviously, any customs procedure, and those from South Africa, which come through Heathrow under a fast-track procedure, are virtually identical; there is no significant difference at all. Our membership of Euratom does not in any significant way influence our access to the world market in isotopes. Therefore, our leaving the EU does not make much difference to how we get in our medical isotopes.
However, we need to have this IAEA-accredited regime, and, obviously, there is not enough time for the four essential nuclear partners to get NCAs through their Parliaments before March next year. But given that the Government have committed to an implementation period, we should be able to agree with Euratom that we remain a member of that organisation and therefore we will be able to continue to operate under its standards for that period.
