This was one of programme of planned inspections at the Low Level Waste Repository during 2019/20, developed in accordance with the Decommissioning Fuel & Waste Sub-Division strategy. This inspection constituted the licensee’s annual demonstration of its emergency arrangements through a combined safety and security exercise.
A team of ONR inspectors, including the nuclear safety site inspector, a Leadership & Management for Safety specialist inspector, the nuclear security site inspector and two further inspectors from ONR’s Civil Nuclear Security & Safeguards Division, observed the demonstration exercise to test implementation of LLWR’s emergency response arrangements.
ONR observed key aspects of LLWR’s emergency arrangements, with focus on command & control, the interface with responding emergency services, and control of an incident with potential on-site radiological consequences. Areas of good practice were noted and advice offered regarding opportunities for improvement. ONR’s judgement of the security aspects are recorded in a separate Intervention Record.
The combined Level One emergency and security exercise was assessed by ONR as an adequate demonstration of the licensee’s ‘on site’ emergency arrangements.
