Inspection of the Control of Radiation Exposure

Executive summary

Purpose of intervention

This report describes an inspection of the Low Level Waste Repository Limited licensed site (referred to as LLWR in this report). This was a planned ONR intervention, as part of the 2016/17 planned intervention programme for the site. The planned intervention was looking at Control of Radiation Exposure (CORE).

Interventions Carried Out by ONR

During the intervention a compliance inspection was undertaken of The Ionising Radiations Regulations 1999.

The intervention was conducted principally under regulation 8 of the Ionising Radiations Regulations 1999 (IRR99). To ensure consistency with previous CORE inspections, the inspection was conducted using a standard questionnaire and follow up face-to-face question and answer session with key representatives at LLWR. During the intervention we viewed application of arrangements for controlling radiation exposure by making a number of visits to the magazine areas, vaults, grouting facility as well as storage buildings for waste drums from the decommissioning campaign.

Explanation of Judgement if Safety System Not Judged to be Adequate
