BEPPS meaning

BEPPS refers to the Box encapsulation Plant Product Store at the Sellafield nuclear site in Cumbria, operated by Sellafield Limited, together with its Direct Import Facility (DIF). In practice, it denotes the purpose-built store for intermediate‑level radioactive waste (ILW) packages produced by the Box Encapsulation Plant and, via the DIF, the direct receipt of compatible packages from other authorised plants. It is a descriptive project term used across contracts, licences, permits and planning documentation; it is not defined in legislation or case law. BEPPS/DIF is now constructed and in phased commissioning/operation. Legal references commonly concern: regulatory approvals and safety cases under the Office for Nuclear Regulation (ONR) nuclear site licence, Environment Agency environmental permitting, waste acceptance criteria and capacity limits, security and safeguards obligations, and transport/interface arrangements for importing and storing ILW packages. The facility’s milestones, operating envelope and acceptance criteria frequently feature as conditions precedent, programme milestones and risk/liability allocation in procurement and construction agreements, and in decommissioning strategies. Usage is broadly consistent across England & Wales, Scotland and Northern Ireland within the UK nuclear regulatory framework. In Ireland, the term is referenced descriptively in cross‑border environmental and energy contexts but has no standalone statutory definition.
