Compliance against the Ionising Radiations Regulations 2017

Executive summary

Purpose of Intervention

This was a planned inspection in line with the ONR Integrated Intervention Strategy (IIS) plan for 2020/21, of the BAE Systems Marine Ltd (BAESM) radiography bay enclosure in the D59 facility.

Interventions Carried Out by ONR

The intervention consisted of a remote compliance inspection against the Ionising Radiations Regulation 2017 (IRR17) arrangements. The intervention will inform ONR of the maturity of design and test design/development, to prove design intent and compliance with regulatory standards and internal regulatory controls applied by BAESM. It is intended to de-risk the plans for future build, installation, and operations of the facility.

The inspection sampled the arrangements including those for the critical examination and (to a lesser extent) routine operation. This included Radiation Risk Assessments (RRA) and local rules.

During the IRR17 inspection, I held telephone discussions with managers, supervisors, operators and Radiation Protection Advisers (RPA) from BAESM, partners, contractors and installers to obtain evidence to determine the level of compliance. I sampled relevant documentation and assessed compliance against:

Explanation of Judgement if Safety System Not Judged to be Adequate

Not Applicable

Key Findings, Inspector's Opinions and Reasons for Judgements Made

No matters were identified requiring immediate regulatory attention during the inspection.

I concluded that there were no significant shortfalls identified against Relevant Good Practice (RGP), with respect to Radiological Protection requirements under IRR17.

I did however observe a minor shortfall in relation to Regulation 14 of the IRR17 - Radiation Protection Advice, related to the duty holder seeking radiation protection advice from the Radiation Protection Adviser in a timely manner. This was specifically regarding the configuration of the personal access door to the radiography enclosure bay. I will track this minor shortfall to closure via a level 4 issue, which will be managed through routine level 4 meetings between the duty holder and myself.

Conclusion of Intervention

Based on the sampling undertaken during the IRR17 remote compliance inspection, I am satisfied that the duty holder has adequate arrangements for compliance with IRR17.

Therefore, I consider that an inspection rating of Green (no formal action) is merited.
