Nuclear: Small Modular Reactors

Lord Morse Excerpts

Monday 19th May 2025 Lords Chamber

[Lord Hunt of Kings Heath (Lab)]

My Lords, the noble Lord is referring to the road map issued by the last Government. He will know that unfortunately it was not backed up by any concrete plan or resource, so we are having to pick up the pieces. I cannot yet give him the answer on the mix between SMR and major-gigawatt plants. We are clearly alongside the SMR programme. We are moving rapidly towards final investment decision on Sizewell C, which is 3.2 gigawatts. That follows Hinkley Point C, where EDF says the first unit will open between 2029 and 2031. Over the next few months we will work very hard to look at the potential of SMRs, gigawatts and the advanced modular reactors and give industry a sense of where we are going in order to give it the security and certainty it needs to develop the supply chain we want to see.

[Lord Morse (CB)]

My Lords, I declare an interest as a resident of Suffolk. I mention that because to understand the context of small nuclear reactors, it is worth while understanding the progress being made—or not—on the large nuclear reactors. Is it true that the new Sizewell nuclear reactor is not yet funded and that, while it is throwing concrete around north Suffolk, there is no contractual basis for doing so?

[Lord Hunt of Kings Heath (Lab)]

My Lords, I congratulate the noble Lord on living in Suffolk. Only a few weeks ago I had a meeting with Suffolk local authority leaders to discuss these very matters. He is right in the sense that, as I have already said, we are moving rapidly towards final investment decision on Sizewell C. I very much hope we will be able to get that over the line. We have committed £2.7 billion of funding through the Sizewell C devex subsidy scheme to support the project’s development during the current financial year. It consolidates the Government’s position as the majority shareholder in Sizewell C and is laying the foundations for final investment decision and, we very much hope, a 3.2-gigawatt nuclear power station that will power 6 million homes for 60 to 80 years.
