This was a system based inspection of LLWR's fire protection system as one of a planned series of inspections during 2017/18.
My Inspection examined LLWR's implementation of the drum store's safety case for fire protection systems. The six licence conditions (LCs 10, 23,24,27,28 and 34) were inspected.
These findings refer to my ratings of LLWR's arrangements for compliance with the applicable licence conditions (10, 23, 24 and 28) for the facility's fire protection system (FPS).
Training (LC10); management arrangements adequately demonstrate the availability and delivery of appropriate training programmes and complementary process for staff assessment, and appointment, reassessment, with compliance assurance processes to provide and deploy suitably qualified and experienced personnel (SQEP) responsible for supporting the FPS. This includes; safety case personnel whose assessment is used to derive the necessary safety measures required; operational personnel who use it and maintenance personnel who assure its availability for use.
Operating Rules (LC23) and Operating Instructions (LC24); I found no shortfalls in LLWR's
arrangements for producing the facility safety case, which is subject to systematic peer review and endorsement before implementation. In my opinion the safety case presented a clear
basis for implementing the store facility's fire protection systems, and identification of a single operating rule, with associated operating instruction for a specific aspect of fire safety.
Maintenance (LC28); I found adequate arrangements in place for regular testing and periodic maintenance of the facility's fire detection and alarm system (FDAS). Maintenance is only carried out by experienced (SQEP) staff, using detailed maintenance instructions and supervision and checking of completed work, for which completed records were sampled and found to be adequate. The FDAS is the only 'mitigating' safety measure for two fire fault sequences assessed in the facility safety case.
I found no shortfalls in any of the arrangements and records which I examined in support of my inspection for these licence conditions. In my opinion LLWR demonstrated that the fire safety case was adequately implemented for the fire protection system in the drum store.
