Technical Specification 5.4.1.d required that
PG&E implement a
fire protection program. The
fire protection program requirements, as described by
FSAR Section 9.5, Appendix 9.5a, Fire Hazards Analysis, required that Fire Door 105 be maintained as a fire area boundary and the
carbon dioxide suppression system be maintained for protection. Contrary to the above, between January 12, 2007, and May 28, 2008, plant personnel failed to maintain Fire Door 105 as a fire boundary and failed to ensure the
carbon dioxide suppression system was
operable. This was identified in the licensees corrective action program as
AR A0731222. This finding is of very low safety significance because it does not impact the ability of Unit 1 to reach and maintain
safe shutdown in the event of a fire in Fire Area TB-1
