Site inspection to ensure compliance with the Regulatory Reform (Fire Safety) Order 2005

Executive summary

Purpose of Intervention

This was a planned inspection at Sizewell B Nuclear Power Station, undertaken as part of the intervention strategy for Operating Facilities Division.

The purpose of the intervention was to ensure that the Licensee was demonstrating compliance with the requirements of the Regulatory Reform (Fire Safety) Order 2005 to ensure the safety of people from the danger of fire.

Interventions carried out by ONR

This intervention was a planned remote Compliance Inspection undertaken against the life safety requirements of the Regulatory Reform (Fire Safety) Order 2005.

The intervention was completed remotely due to COVID-19 restrictions. ONR could not therefore directly inspect the implementation of fire safety management procedures or assess directly the effectiveness of the activities being undertaken on the site or independently confirm actual compliance with Company processes.

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

The Fire Coordinator is new in post and undergoing appropriate training and mentoring. The role is supported by a SQEP assistant who provides resilience in maintaining fire safety standards and will provide the Coordinator the opportunity to undertake professional development.

Site’s monitoring and monthly analysis of unwanted fire alarm signals combined with proactive intervention, is an example of industry best practice in the management and reduction of false alarms.

Progress on the following items, identified during the last site inspection, has been good and not adversely affected by virus precautions;

I did not identify any significant departures from compliance that will require follow up as part of regulatory interactions. No matters were identified as requiring immediate regulatory attention during the course of the compliance intervention.

Conclusion of Intervention

I concluded that the sampled areas of fire safety arrangements, within the limitations of remote inspection, are compliant with the legislation and demonstrate best practice in management of false alarms.

I have rated the outcome of this inspection as GREEN.
