Unit 1 and 2 Facility Operating Licenses, Condition 2.C.5,
Fire Protection Program, required that the licensee shall implement and maintain in effect all provisions of th
approved
fire protection program as described in Section 9.5.1 of the
UFSAR as amended and approved in the safety evaluation report through Supplement 5. Safety Evaluation Report Section 9.5.1.8, Fire Protection for Specific Station Areas, stated in part, that each
DG is located in a different fire area separated by a threehour fire rated wall and that all cable and piping
penetrations through the fire rated barriers are fitted with a three-hour fire rated
penetration seal. 14 Contrary to the above, from October 2008 until November 2014, provisions of the approved
fire protection program were not maintained in effect for the
DG area.
Penetration Firestop 306W102, separating 2A and 2B
DG rooms, was determined to be non-functional due to inadequate filler material. This represented a degradation of the separation requirements for a three-hour
fire barrier. The licensee initiated
PIP C-14-10350 to address and correct this issue. This finding screened as Green according to
Inspection Manual Chapter 0609, Appendix F, Fire Confinement (Task 1.4.3) due to the presence of a fully functional automatic suppression system on either side of the
fire barrier.
