Title | High Pressure Coolant Injection Room Sprinkler System Failed to Protect Against Hazard |
Description | A finding of very low safety significance and an associated NCV of the Fermi 2 Facility Operating License Condition 2.C(9), for the fire protection program, was identified by the inspectors for the failure to ensure the adequacy of a sprinkler system in Fire Zone 03RB. Specifically, the licensee failed to ensure that the capability of the sprinkler system installed in High Pressure Coolant Injection (HPCI) pump and turbine room (Fire Zone 03RB) was adequate to protect against the identified lubricating oil hazard of the HPCI turbine. The licensee entered the issue into their corrective action program and established hourly fire watches in Fire Zone 03RB as a compensatory measure. The finding was more than minor because it affected the mitigating systems cornerstone attribute of protection against external factor (fire) and it impacted the objective of the mitigating systems cornerstone. The failure to ensure that the sprinkler system installed in Fire Zone 03RB protected against a fire involving the HPCI turbine impacted a defense and depth element of the fire protection program. The inspectors concluded that the finding was of very low safety significance because the majority of the mitigating systems were not being affected by the finding |
