Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how many designs for small modular reactors have been submitted for Generic Design Assessment to the Office of Nuclear Regulation; and if he will list the (a) date of submission, (b) stage of assessment process and (c) anticipated programme for each to get to design approval.

In April 2022, the nuclear regulators began a Generic Design Assessment (GDA) looking at the safety, security, and environmental impact of the Rolls-Royce SMR Ltd reactor design, which is the first Small Modular Reactor design to be assessed in the UK.

The Office for Nuclear Regulation (ONR) publishes and maintains information on current and completed Generic Design Assessments on their website, which can be found at the following link: https://www.onr.org.uk/new-reactors/assessment.htm.
