Fire safety inspection at Urenco UK Ltd

Executive summary

Purpose of intervention

    Seven months has passed since my previous inspection of the TMF construction project. This inspection focused on the B buildings, C buildings and Contractors Village relating to the TMF site.

The purpose of the inspection was to ensure that the Licensee was achieving compliance with the requirements of the Regulatory Reform (Fire Safety) Order 2005. The inspection focused on both the management of fire safety and the practical fire safety provision. The legislation focuses on life safety not nuclear fire safety issues.

The main purpose of the COP fire safety inspections is to ensure adequate life fire safety provision exists across all nuclear licensed sites.

Generally the fire safety arrangements were ADEQUATE.

Interventions Carried Out by ONR

This Intervention forms part of a series of on-going inspections / meetings forming a key element of the assessment of fire safety across the TMF site. My inspection assessed the duty holders’ compliance with the requirements of the Regulatory Reform (Fire Safety) Order 2005. Of particular interest during this inspection were the fire safety conditions within the relevant buildings when inactive commissioning is progressing. The commissioning process has resulted in the introduction of a significant amount of plant and equipment within the buildings which has added to the complexity of the internal layout.

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

Since my last inspection, the introduction of plant and equipment into a number of the buildings continues at pace and adds to the dynamic nature of this busy construction site. The project continues to move towards and has commenced inactive commissioning. The fire main to the west side of the B and the b building dry risers have been commissioned. No other fire safety systems have currently been commissioned.

I was provided with a very informative presentation (copies to be provided at a later date) by TM the Jacobs Fire Engineer which provided a clear overview of the progress made since my last inspection with a particular focus on any impact on the fire safety strategy for the final design of the overall facility.

The presentation described the current fire safety management structure. This is made up of Jacobs, Balfour Beatty and UCP safety personnel. The role of the Fire Engineer and the Jacobs FSC is pivotal in applying the day to day management of fire safety across the TMF construction site. In particular, the near completion of the C buildings is taking up the majority of their time in the day to day management of fire safety. I identified a small number of actions, observations and recommendations which are described in the main body of the report.

AMR provided an update on the progress relating to emergency arrangements and the anticipated sectional hand over later in the year.

Conclusion of Intervention

From the evidence gathered during this intervention I am satisfied that the continued level of focus on fire safety being demonstrated is appropriate. I have reiterated the need to maintain the current standards as the commissioning phase develops. I have suggested that consideration should be given to the integration of the Jacobs Fire Engineer and FSC with the UCP safety team so as to add value to the sectional handover of areas of the plant during the forthcoming months. I will continue to complete on-going review inspections at regular intervals, particularly as the project moves towards the commissioning phase
