Decommissioning & waste
Decommissioning is the biggest single source of nuclear engineering work in the UK, and Sellafield is the most complex site in Europe. These vacancies cover retrievals, waste characterisation and packaging, effluent treatment, remediation and post-operational clean-out — from technician grades to safety case and programme leadership.

Most technician and operator roles ask for a relevant Level 3 qualification (mechanical, electrical, process or laboratory) plus site-based radiological training, which employers usually provide. Engineering and safety case roles normally want a degree or HND in a science or engineering discipline with demonstrable nuclear or heavily-regulated experience.
BPSS is the baseline for site access. Roles touching sensitive material, security systems or defence-adjacent work will typically require SC, and a small number require DV. Clearance is sponsored by the employer once you have an offer.
Sellafield's mission is funded and planned over decades, so decommissioning is the most stable long-term work in the Cumbrian nuclear cluster — both for permanent staff and for contractors on rolling supply chain assignments.
