My Lords, I declare an interest both past and present in this area. I welcome the support the Government have so far given to SMR development in this country. Of course, it is going on in many other countries as well. How does this play out in relation to the plan at Sizewell C, where the idea is to build another large-scale reactor as a replica—I repeat, replica—of Hinkley Point C? Hinkley Point C has had its own problems; it is over time, over budget and has component difficulties. Do we really want to think in terms of a large-scale replica there or in other sites, when the SMR option is coming on fast? We are at the edge of new technology in nuclear power; should the Government not think very carefully before deciding between SMRs and another large-scale reactor with all its problems, as already indicated?
