To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to ensure the waste heat from SMR turbine halls is used in a way that contributes to achieving net zero.

Answer

Michael Shanks

Small Modular Reactors (SMRs) will play an important role in helping the UK achieve our energy security and net zero ambitions. Government recognises the potential role of SMRs in energy sectors beyond electricity generation, including as a source of low carbon heat.

The department will shortly be publishing a new policy framework which will lay out pathways for privately led advanced nuclear projects to be brought forward in the UK. Great British Energy – Nuclear will take on a new role in assessing proposals, with the National Wealth Fund exploring potential investment opportunities.
