Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what comparative assessment he has made of the potential merits of PWR nuclear reactors and molten salt reactors in the context of the Government's plans for new nuclear power stations in the UK.

The Government has commissioned several comparative assessments of nuclear energy technologies over the last decade, many of which have included consideration of Molten Salt technologies.

The outputs of these assessments were considered, alongside other evidence sources, in the development of the “Advanced modular reactors (AMRs): technical assessment” published in July 2021 as part of the decision on the technology choice for the Advanced Modular Reactor (AMR) Research, Development & Demonstration (RD&D) programme.
