An NRC-identified
NCV of the McGuire Unit 1 and Unit 2 Renewed Facility Operating License Condition 2.C.4,
Fire Protection Program (
FPP), was identified for the licensees failure to adequately control the storage of
transient combustibles in the 2A
residual heat removal (ND)/containment spray (NS) heat exchanger room near
safe shutdown equipment in accordance with the
FPP requirements. The licensee initiated immediate corrective actions to evaluate the
transient combustible fire loading and remove all the unapproved
transient combustibles from the area. This condition was placed in the licensees corrective action program (
CAP). The licensees failure to control the storage of
transient combustibles in accordance with procedure NSD 313 was more than minor because it was associated with the
Mitigating Systems cornerstone attribute of Protection Against External Factors (Fire) and adversely affected the cornerstone objective in that a fire involving
transient combustibles could have affected nearby power cables and motor operator for valve
2ND-58A which provides a
safe shutdown mitigation function. The finding was determined to have very low safety significance (Green) because it did not affect the ability of the reactor to reach and maintain cold shutdown condition. This finding had a cross cutting aspect of Teamwork in the Human Performance area because multiple groups were responsible for bringing the
transient combustibles into the area and the individuals failed to effectively communicate and coordinate their activities to ensure that
transient combustible control processes were appropriately implemented.
