Chief Nuclear Inspector’s annual report on Great Britain’s nuclear industry
Posted: 8th October 2025
Chief Nuclear Inspector’s annual report on Great Britain’s nuclear industry. The climate change themed inspections spanning 2023 to 2025 have not identified any fundamental safety or security issues, medium and long term resilience improvements are needed, which we will follow-up through future industry engagements. There have been many highlights throughout the year including: Hunterston B’s defueling; the nuclear site licence for Sizewell C; we permissioned a number of high hazard risk recovery activities at Sellafield Ltd to facilitate storage of material recovered from the legacy ponds and silos; we permissioned the docking of two nuclear submarines at Devonport Royal Dockyard in 9 and 15 docks ahead of required timescales; we permissioned installation of the Unit 1 reactor pressure vessel at Hinkley Point C, the first such activity in the UK for 30 years.
