Sizewell B - Fire Safety Inspection

Executive summary

Purpose of Intervention

The purpose of this Intervention was to confirm that the General Fire Safety provisions on site are adequate, and to confirm that compliance with the requirements of the Regulatory Reform (Fire Safety) Regulations 2005 (RRO) is being achieved by the licensee. The visit is part of a planned series of interventions across all programmes.

Interventions Carried Out by ONR

As part of this intervention:

The site gave access throughout the day to senior managers and subject area experts to provide evidence of compliance with the RRO, and the adequacy of their fire safety management arrangements through examination of pre-prepared material and responding to questions. I challenged managers’ statements and questioned personnel to test effectiveness and knowledge of arrangements.

Two separate areas of the site were inspected, including the CWP, and the Maintenance Workshop and Stores Building, and there was a good positive culture of openness to reviewing all areas we visited.

Explanation of Judgement if Safety System Not Judged to be Adequate


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

There were no issues identified during the previous intervention, and the site has always reacted in a positive way to any fire safety issues identified. On this occasion, it was however necessary to raise 4 regulatory issues, all of which individually are minor in nature, but are warranted for further investigative and remedial actions.

In conclusion, the site has a good appreciation of how important fire safety is and what impact a fire would have on site, as evidenced by a suitable and sufficient fire risk assessment process. Consequently, I have therefore rated this inspection as Green. No further regulatory action is required.

Conclusion of Intervention

Despite the observed minor issues relating to shortfalls in regulatory compliance identified as part of this intervention, the response of site management throughout was very positive throughout, and this was communicated to the site management team at the time
