Event Notification Report for August 07, 2014

RADIATION MONITORING COMPUTER SYSTEM INOPERABLE DUE TO PRE-PLANNED MAINTENANCE

"On August 7, 2014 at 0730 EDT, the Unit 2 Radiation Monitoring Computer System will be inoperable and unavailable due to pre-planned maintenance to implement an upgrade to the system. Alternate methods for monitoring are being utilized. The Radiation Monitor Computer System is expected to be restored to available status at approximately 2000 EDT on August 7, 2014.

"This notification is being made in accordance with 10CFR50.72(b)(3)(xiii), as an event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability. An update will be provided once the Radiation Monitoring Computer System has been restored to normal operation. The NRC Resident Inspector has been notified."

EMERGENCY OPERATIONS FACILITY AIR CONDITIONING OPERATING AT REDUCED CAPACITY

"At 0925 [CDT] on 08/07/14, a Condition Report was initiated identifying that one of the two air conditioning condenser coil fans for the CPNPP [Comanche Peak Nuclear Power Plant] Emergency Operations Facility (EOF) air conditioner was damaged. With low outside air temperatures, the air conditioner can adequately maintain habitability of the EOF with one of the two air conditioning fans not working. However, outside air temperatures at CPNPP are forecast to reach 100 degrees F later today, and it is believed that the air conditioner will likely trip due to the increased load. With the air conditioner out of service and outside air temperatures near 100 degrees F, the EOF may no longer have the capability for protracted operation under emergency conditions. Compensatory measures are currently in place to staff and activate the Alternate EOF in the event of a declared emergency. Repair of the damaged air conditioning condenser coil fan is scheduled to be completed by the end of the day on 08/08/14.

"The NRC Resident Inspector has been informed."

UNANALYZED CONDITION DUE TO DISCOVERY OF DEGRADED FIRE BARRIER WALLS

"During a fire inspection activity involving inspection of fire walls that serve as Appendix R barriers, degradation of some fire walls was identified that was sufficient to prevent these walls from meeting Appendix R requirements as 3-hour fire barriers. In the event of a postulated fire in the affected areas, both safe shutdown paths on the affected unit 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 already in place in accordance with the plant's Fire Hazard Analysis (FHA) as a result of previous conditions involving degraded penetrations in these same fire areas. 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 conditions can be corrected.

In addition to automatic fire protection features, the licensee has posted fire watches as a compensatory measure.

In the event of a postulated fire in the affected areas both safe shutdown paths on Unit 1 could be compromised. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).

"As part of the 'extent of condition' corrective action for the condition identified in EN# 50351, an inspection activity is in progress to inspect the remaining fire walls and associated penetrations for conditions similar to those reported on 08/07/2014. During this inspection, nonconformances of multiple fire barriers were identified that bring into question the functionality of the affected fire barriers that can compromise safe shutdown paths on Unit 1 and 2 based on the respective inspection results. Since additional time is required to further evaluate each nonconformance to conclusively determine if the nonconformance is sufficient to consider the barrier nonfunctional, interim conservative fire actions were taken by considering these fire barriers as nonfunctional. Based on this conservative conclusion, in the event of a postulated fire in the affected areas both safe shutdown paths on Unit 1 and 2 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 already in place in accordance with the plant's Fire Hazard Analysis (FHA) as a result of previous conditions involving degraded penetrations and fire walls in most of these same fire areas and will remain in place until the barrier(s) are repaired. Additional fire actions were taken as required to address the additional fire areas identified. 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 is repaired. The inspection activity is continuing, and this and any subsequent similar condition(s) that meets the reporting requirements will be included in an ENS Update Report and will be documented in a revised LER at the end of the inspection activity.

"During an expanded scope inspection for penetration seals, using more intrusive tools and methods, fire barriers in the Control Building El. 112 [foot] were found not to meet acceptance criteria. The fire protection engineering staff has examined the situations and recommends that these conditions be considered NON-FUNCTIONAL.

- An issue was identified with the wall separating the el. 112 [foot] Control Building Working Floor, Fire Area (FA) 0001 from the Station Battery Room 1B, FA 1005.
- An issue was identified with the wall separating the Station Battery Room 2A, Fire Area (FA) 2004 from the Station Battery Room 2B, FA 2005, on el. 112 [foot].

"The nonconforming conditions observed for the affected fire barriers were identified as affecting both safe shutdown paths for Units 1 and 2. Compensatory measures were already in place in accordance with the plant's Fire Hazard Analysis (FHA) as a result of previous conditions involving degraded barriers in the same fire areas and will remain in place until the fire barriers are repaired. The presence of the compensatory measures in addition to portable fire protection equipment located in adjacent areas ensures the safe shutdown paths are preserved until the degraded conditions are repaired. The expanded scope inspection activity is continuing, and this and any subsequent similar condition(s) that meets the reporting requirements will be included in an ENS Update Report as required and will be documented in a revised LER at the end of the inspection activity. CR 10077573 & 10077574."
