Sellafield & decommissioning jobs

Civil nuclear work on the edge of defence, on Europe's most complex nuclear site

Sellafield is civil nuclear work on the edge of defence: an NDA-owned clean-up mission that also handles nuclear materials supporting the UK's deterrent and submarine programmes, sharing clearances, safety standards and supply chains with MOD and naval nuclear work. Delivered largely through Tier 1 and Tier 2 partners, it means a steady pipeline of radiation protection, waste retrieval, safety case, project controls and craft roles across the UK.
