Torness - Fire Safety inspection

Executive summary

Purpose of Intervention

The purpose of this sampled intervention at Torness (TOR) Nuclear power station was to check that the site was compliant with the requirements of the Fire (Scotland) Act 2005 by undertaking a compliance inspection of the licensee’s arrangements that ensure the safety of people from the danger of fire during Reactor 2 outage. This is in line with the inspection programme contained in the TOR integrated intervention strategy (IIS) for 2018/19.

Interventions Carried Out by ONR

My Intervention targeted the measures adopted to maintain compliance with the requirements of the Fire (Scotland) Act 2005 due to changes in the fire risk profile caused by the outage. Prior to my arrival on site I examined a series of fire risk assessment documents in preparation for the inspection.

Throughout my inspection, I was accompanied by the Fire Safety Coordinator who provided answers to questions and supplied evidence of the fire safety arrangements. I spoke with several members of staff preparing for hot work within the Reactor Building and examined the area surrounding the planned activity and two levels immediately below the work area. I also completed a tour of the Turbine Hall and assessed the means of escape provision from the turbine undergoing maintenance, laydown areas and other access routes affected by the outage activity.

During my inspection, I challenged those accompanying me, and others about procedures and approaches to the practical application of maintaining adequate fire safety provision. I questioned personnel to test effectiveness and knowledge of arrangements.

Explanation of Judgement if Safety System Not Judged to be Adequate

Not applicable

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

No new regulatory issues were identified during my inspection. During the tour of the facilities,  the Fire Safety Coordinator provided additional information about the normal day to day fire safety management arrangements and described the fire engineering details that support the fire risk assessments. Overall, TOR demonstrated a good standard of compliance with the life safety requirements of the Fire (Scotland) Act 2005 and met relevant good practice for process fire precautions in the safe use of hot work in an industrial environment.

My inspection has provided confidence that the fire safety arrangements are effective and implemented to a satisfactory standard. I am of the opinion that the Site displayed an appreciation of the importance of effective fire safety measures within the facilities I inspected and that overall they show a desire to maintain compliance with fire safety legislation.

I found that site had well developed procedures for managing fire safety during outage conditions and that these measures included action to reduce the frequency and extent of fire on return to power.

Conclusion of Intervention

Overall, my findings in relation to the areas I inspected, demonstrate a good level of life/fire safety provision and that suitable fire precautions are in place to support the Consent for the return to power for TOR.  I concluded that the Fire Safety arrangements met legal requirements and have therefore rated this inspection as Green.
