FIRE PENETRATION DID NOT MEET APPENDIX R REQUIREMENTS
"A fire penetration on the Unit 1 reactor building 158 foot elevation was discovered to be degraded such that the associated wall would not meet Appendix R requirements as a 3-hour barrier. In the event of a postulated fire in either of the affected fire areas, separated by the affected penetration, both Unit 1 safe shutdown paths could be compromised. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).
"Compensatory measures were established in accordance with the plant's Fire Hazard Analysis (FHA). The presence of the compensatory measures in addition to automatic fire detection in these fire areas ensure that the safe shutdown paths are preserved until the degraded condition can be corrected.
