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.
"Condition Reports: 850802, 850819"
In addition to automatic fire protection features, the licensee has posted fire watches as a compensatory measure.
The licensee has notified the NRC Resident Inspector.

"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 for conditions similar to those reported on 8/7/2014. During this inspection, another condition was identified involving some degradation of the fire wall between Fire Area 1023 - RPS MG Set Room and Fire Area 1015 - Annunciator Room. 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).
"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 and will remain in place until the wall is repaired.

"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 for conditions similar to those reported on 8/7/2014.

"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 review and closeout of fire barrier and penetration seals work orders and surveillance procedures performed as part of the 'extent of condition' inspection activity initially described in Event # 50351, the following conditions were identified that in the event of a postulated fire in the respective fire areas listed both safe shutdown paths could be compromised.
"Unit 2 Control Bldg. el. 130', gap in the grout around conduit penetration between fire areas 2013 and 2015

"During the review of fire barrier surveillance procedures performed as part of the 'extent of condition' inspection activity for the event initially identified in EN# 50351, some degradation was observed on the east wall of fire area 2006. These nonconforming issues observed on the affected fire wall were identified as affecting both safe shutdown paths for Unit 2. Therefore, in the event of a postulated fire for the affected area, both safe shutdown paths on Unit 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 barriers in the same fire area and will remain in place until the wall is 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 extent of condition 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."

AGREEMENT STATE REPORT - STUCK SHUTTER ON A FIXED GAUGE
The following information was received from the State of Texas via fax:
"On April 7, 2015, the Agency [Texas Department of State Health Services] was notified by the licensee's radiation safety officer (RSO) that they were unable to close the shutter on a Berthold Model LB 300 IRL Type 1 source holder containing three Cobalt - 60 sources. The licensee found the problem during routine checks. The RSO stated they had contacted the manufacturer for assistance. The RSO stated there was no increased risk of exposure to members of the general public or the employees at the facility.

Event Text
OFFSITE NOTIFICATION DUE TO SODIUM HYDROXIDE SPILL ONSITE EXCEEDING REPORTABLE QUANTITY
"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"Arizona Public Service Co. made an offsite notification to the National Response Center regarding an approximately 3500 gallon caustic (8% sodium hydroxide) spill due to an improper valve lineup. The spill occurred at the Water Reclamation Facility (produces water for cooling towers and power plant and is located outside the Security Owner Controlled Area) in the area of the Fire Protection tanks (additional liquid was contained in a containment structure at the release location, and in a nearby concrete lined storm ditch on site). The release has been isolated, the immediate area has been barricaded. The quantity released exceeded the Reportable Quantity for sodium hydroxide (RQ of 1,000 pounds) and was therefore reported. Additionally, the state [Arizona] and county [Maricopa] have also been notified. There was no impact to the operation of the power units, aquifer or personnel onsite or offsite.
"The NRC Resident [Inspector] has been notified." |
