Government Response: Proportionality Action Plan for safety cases

The Government is implementing a Proportionality Action Plan to reset safety case development. Strategic direction will be agreed by the end of Summer 2026, with new methodologies fully embedded by Summer 2027. Oversight will be provided through the Nuclear Standards Forum and the Nuclear Regulatory Implementation Programme (NRIP). The approach aligns with the Taskforce recommendation to eliminate duplication and embed simplicity in the safety case regime.
