- IRR17 - Rating: Green
Key findings, inspector's opinions and reasons for judgement made
This report presents the findings of a planned intervention that was undertaken to assess compliance with the Ionising Radiations Regulations 2017 (IRR17) at the Nuclear Restoration Services (NRS) Dungeness A nuclear licenced site.
The intervention examined the implementation of NRS Dungeness A arrangements used to secure compliance with the requirements of IRR17 through prior sampling of evidence, discussions with key facility personnel and an inspection of facilities. The key requirements examined were those relating to the following IRR17 regulations and areas:
- Regulation 8 – Radiation risk assessments
- Regulation 9 – Restriction of exposure
- Regulation 14 – Radiation protection adviser
- Regulation 15 – Information, instruction, and training
- Regulation 17 – Designation of controlled or supervised areas
- Regulation 18 – Local rules and radiation protection supervisors
- Regulation 20 – Monitoring of designated areas
- Details of any IRR17 events and how these have been addressed.
It is in my judgement that NRS Dungeness A site senior management and Head of Radiological Protection have demonstrated compliance with IRR17 for the regulations sampled. The Head of Radiological Protection understands the current and future radiological challenges associated with the programmed work, has appropriate dose monitoring mechanisms, and has been able to demonstrate those controls. I consider the documents submitted to ONR of a high standard. The radiation risk assessments and supporting documentation provided have confirmed input from Accredited Health Physicists prior to peer review. Where bespoke in nature, or a of high radiation dose, the Radiation Protection Advisor (RPA) body of NRS is also involved in their production.
The findings of this inspection have been shared with, acknowledged, and accepted by the Head of Radiological Protection as part of normal inspection feedback.
Overall, I have judged that, based on evidence sampled prior to and at the time of this on-site inspection, compliance with IRR17 has been demonstrated and an inspection rating of Green (no formal action) is appropriate.
Conclusion
Overall, I have judged that, based on evidence sampled prior to and at the time of this on-site inspection, compliance with IRR17 has been demonstrated and an inspection rating of Green (no formal action) is appropriate
