This report describes an inspection of Magnox Ltd's Wylfa licensed site, undertaken as part of a series of routine interventions set out in the Integrated Intervention Strategy for 2016/17. The intervention also met the requirements of the planned ONR cross sites intervention for Wylfa, which is looking at Control of Radiation Exposure across all licensee sites.
During the intervention a compliance inspection was undertaken on:
The intervention was conducted principally under regulation 8, ‘Restriction of Exposure’, of the Ionising Radiations Regulations 1999. To ensure consistency with previous inspections, the inspection was conducted using a standard questionnaire and follow up face-to-face question and answer session with representatives at Wylfa. During the intervention we inspected the arrangements for controlling radiation exposure by inspecting a number of areas including reactor 1 and 2 pile cap area, plant rooms, offices and radioactive waste storage.
This intervention did not include a safety system based inspection.
Compliance with the requirements of the IRR99 was judged overall to be adequate. ONR advised on a number of areas for improvement in order to achieve a better alignment with published relevant good practice.
Compliance with the Ionising Radiation Regulation 1999 was judged to be of an adequate standard with some opportunities for further improvement identified which were discussed and agreed with the licensee.
