Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what the cost differential per kilowatt is for nuclear development for large scale gigawatt projects and small modular reactors.

Great British Nuclear is currently administering the small modular reactor (SMR) technology selection process and is now in the process of evaluating bids. Given that this is a live procurement process it would be inappropriate at this time to comment on the economics of SMR power generation or to make any comparison across nuclear technologies, but all nuclear projects will be subject to a detailed value for money assessment, including cost.
