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

Executive summary

Purpose of Intervention

This inspection was to ensure that the site is achieving compliance with the requirements of the Regulatory Reform (Fire Safety) Order 2005. The inspection focused on the management of fire safety and the progress being made to assure compliance with the relevant fire safety legislation will be met for the newly constructed Tails Management Facility (TMF). The legislation focuses on life safety not nuclear safety related fire matters.

Interventions Carried Out by ONR

This inspection forms part of a series of inspections forming a key element of the assessment of fire safety across the TMF complex. The project has entered a transitional phase. This inspection focused on the assessment of the final design relating to fire safety. Clarity was sought as to the progress relating to the completion of and commissioning of both active and passive fire safety systems. A specific focus for discussion related to the on-going assessment of the locking mechanisms that had been fitted to the internal fire doors in the facility.

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

Since my last inspection the site has moved from the construction phase to inactive commissioning and the further transition to active commissioning (subject to ONR agreement). The numbers of workers across the site has decreased significantly. Work continues to address the issue relating to locks that have been fitted to numerous doors that form part of escape routes. Further issues have been identified relating to other doors in relation to the quality of doors, and in particular some of the handles. It is thought that some of the doors affected by the poor quality will be fire-rated doors and as such assurances will be required to confirm that the fire rated performance of these doors will not be compromised.

Conclusion of Intervention

I am satisfied that the level of focus on fire safety continues and is understood to be an area of particular importance in the regulatory process leading up to active commissioning and operations. I am expecting to be provided with the outcome of the on-going works to address the removal of the locking mechanisms on the doors which make up part of certain means of escape routes. The project looking into the quality concerns relating to door ironmongery also rates highly as far as the areas where greater evidence will be required to afford confidence relating to the fire strategy being employed.
