A
Severity Level IV NCV of Farley Unit 1 Operating License Condition 2.C.(4) and Farley Unit 2 Operating License Condition 2.C.(6) was identified for the licensee making a change to the approved
fire protection program (
FPP) without prior Commission approval. On January 20, 1992, and February 20, 1998, the licensee inappropriately used the
10 CFR 50.59 change process to revise the
FPP to accept five fire areas (Fire Areas 51, 1-004, 1-042, 2-004, and 2-043) that did not satisfy the fire detection and suppression requirements of
10 CFR 50, Appendix R, Section III.G.3. These five fire areas contained unprotected, redundant electrical cables for both main control room (
MCR) air conditioning (A/C) units. On Unit 1, the change decreased the effectiveness of the program in the event of a fire, while on Unit 2 the change adversely affected the ability to achieve and maintain
safe shutdown (SSD) in the event of a fire
The team concluded that the finding had a credible impact on safety because the licensees failure to properly evaluate changes to the
FPP could adversely affect or degrade the reliability of SSD capability from the
MCR. However, the team determined that this finding was of very low significance because the overall SSD capabilities in the affected fire areas and related FFP features were still adequate to ensure SSD capability. Therefore, this finding is characterized as Green.
