Energy: Small Modular Reactors

Question: To ask the Secretary of State for Energy Security and Net Zero, what share of the UK's energy requirement does he estimate will be met through Advanced Modular Reactors by 2036.

Answer: HMG believes advanced nuclear technologies, including Advanced Modular Reactors (AMRs), could play an important role as a low-carbon energy source that would support a secure, affordable decarbonised energy system. AMRs have the potential to be less capital expensive to build than traditional nuclear power plants, because of their smaller size, factory-based modular build, and greater flexibility in deployment. We are actively progressing the deployment of advanced nuclear projects through a clear policy framework, including both Small Modular Reactors (SMRs) and Advanced Modular Reactors (AMRs). The newly published Framework lays out pathways for privately led advanced nuclear projects to be brought forward in the UK.
