Dounreay Compliance inspection

Executive summary

Purpose of intervention

I carried out planned inspections of compliance with licence condition (LC) 21 (commissioning) in accordance with the 2015/16 integrated inspection strategy (IIS) for Dounreay, to provide confidence that the licensee is controlling its hazards properly and complying with its statutory obligations

Interventions Carried Out by ONR

I inspected the licensee’s arrangements for compliance with LC 21, using the proposed Dounreay exotics programme as an example.  I inspected the licensee’s implementation of its arrangements at PFR using the wet area size reduction facility as an example.  I inspected the licensee’s new training course for people from non-nuclear backgrounds.

Explanation of Judgement if Safety System Not Judged to be Adequate

N/A

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

Overall I am satisfied that the licensee has a robust system for capturing commissioning requirements and recording their completion to demonstrate that safety claims are satisfied.  Work is carried out using the site’s usual works control process, and variations are made using the site’s usual modifications process.  The use of these common processes provides confidence that the commissioning themselves are carried out safely.  I therefore consider compliance with LC 21 to be adequate.

I consider the licensee’s new training course for people from non-nuclear backgrounds to be professionally designed.  It makes good use of case studies and practical examples to drive home significant points.  The delegates I interacted with displayed a high level of knowledge, as I would expect from a nuclear professional.  Indeed, I consider that the course would be of benefit to experienced personnel as well.  I therefore consider compliance with LC 10 in this area to be good.

Conclusion of Intervention

I did not identify any matter impacting on nuclear safety that required immediate regulatory action.
