Sellafield Limited - IRR17 inspection of Magnox East River
- Site: Sellafield
- IR number: 18-141
- Date: October 2018
- LC numbers: N/A
Purpose of Intervention
This report presents the findings of a planned intervention that was undertaken at the Sellafield nuclear licensed site in order to assess Sellafield Limited’s (SL) compliance with the Ionising Radiations Regulations 2017 (IRR17) within Magnox East River (MER) facilities.
The intervention was the second of six planned interventions across the Sellafield site examining the standard of radiological protection culture and practice across multiple operating units.
Interventions Carried Out by ONR
The intervention consisted of an examination of the implementation of arrangements to secure compliance with the requirements of IRR17 by discussion with key facility personnel and inspection of plant. The key requirements examined were those relating to:
- Regulation 9 (Restriction of exposure);
- Regulation 14 (Radiation Protection Adviser);
- Regulation 15 (Information, instruction and training); and
- Regulation 18 (Local rules and radiation protection supervisors)
Explanation of Judgement if Safety System Not Judged to be Adequate
Not applicable, this was not a System Based Inspection.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
Based on the work areas and work activities examined, I found that arrangements for the control of work with ionising radiations within MER were adequate. In particular:
- The arrangements in place for the regular (monthly and quarterly reviews) of worker doses appeared adequate and proportionate to the external doses received by workers within the facilities;
- I considered that Sellafield’s arrangements for compliance with IRR regulation 14(2) are adequate;
- The three Radiation Protection Supervisor and one Radiation Protection Supervisors who were interviewed on plant, demonstrated a clear understanding of the requirements associated with their roles and appeared to be suitable for those roles.
- The two Health Physics Shift Team Leaders interviewed demonstrated a thorough understanding of radiological hazards on plant and their responsibilities during both normal operations and in the event of contingency plans or emergency plans being implemented in response to radiological events.
- From the responses provided by the six personnel interviewed, I identified no concerns relating to compliance with IRR17 regulation 15 – Information, instruction and training.
- Local Rules contained appropriate information and were prominently displayed at the required locations.
Conclusion of Intervention
From what I observed and examined, the arrangements for the control of work with ionising radiations and their implementation indicate that there are no significant shortfalls of compliance with the Ionising Radiations Regulations 2017 (IRR17) within MER. I rated the interventions as Green (No Formal Action). No matters that required a regulatory issue to be raised were identified during the intervention.
