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 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.

"Unit 1 is entering a planned outage due to unrelated activities."

HIGH HEAD SAFETY INJECTION INOPERABLE DUE TO MISSING PIPING SUPPORT

"This is a non-emergency 8 hour report in accordance with 10 CFR 50.72(b)(3)(ii)(B).

"At 1750 [EST] hours on 2/10/15, Unit 4 entered Technical Specification 3.0.3 due to missing tubing supports identified for two separate high point vent lines. This condition is unanalyzed and potentially rendered the cold leg High Head Safety Injection flow path inoperable. Upon discovery, the vent line root isolation valves were closed and Technical Specification 3.0.3 was exited at 1805. Investigation has been initiated to determine cause."

The licensee has notified the NRC Resident Inspector.

* * * UPDATE AT 1250 EDT ON 03/31/15 FROM ERIC JUERGENS TO S. SANDIN * * *

The licensee is retracting this report based on the following:

"On 2/11/2015 at 0103 EST, Event Notification 50807 reported to the Nuclear Regulatory Commission Operations Center (NRCOC) the potential inoperability of the Unit 4 cold leg High Head Safety Injection (HHSI) piping due to missing tubing supports on two separate high point vent lines.

"Subsequent analysis has determined that the Unit 4 HHSI cold leg injection flow path to the reactor coolant system (RCS) remained operable with the missing vent line tubing supports and its safety related function was not affected.

"The Unit 4 HHSI system discharge flow path to the RCS had been operable with the missing vent line tubing supports, Technical Specification (TS) requirements were met, and entry into TS 3.0.3 was not required. The HHSI system remained capable of fulfilling the safety function to mitigate the consequences of an accident on Unit 4. Therefore, the immediate notification to the NRCOC on 2/11/2015 at 0103 EST in accordance with 10 CFR 50.72(b)(3)(ii)(B) is hereby retracted."

AGREEMENT STATE REPORT - MISSING FIXED GAUGE SHUTTER

The following report was received via e-mail:

"On 02/26/2015, the RSO for Boise Cascade called in a preliminary report [to the Louisiana Department of Environmental Quality] about a shutter missing on a gauge to be 'locked out' during a 24 hour turn-a-round. The shutter is a manual sliding port cover that has to be removed when the gauge is used on the process. The removed shutter is stored by placing it on an adjacent surface until needed. Vibrations on the process had caused the port cover to fall approximately 50 ft. below the storage locations. However, this time the cover could not be located and the gauge could not be locked out. The gauge remained on the process until it could be repaired.

"On 02/26/2015, a replacement shutter/port cover was ordered from Thermo Measuretech. The shutter was delivered on 02/27/2015 and installed the same day. There was no radiation exposure risk to the public or workers. The gauge is installed on a 50 ft. elevation and the unshielded radiation field is approximately 0.3 mR/hr at 1 ft. from the surface of the device.

"The gauge was a Texas Nuclear Device, TN 5192, s/n B3421 containing approximately 100 mCi of Cs-137 when installed during the mid-1980s.

"The Department [Louisiana Department of Environmental Quality] considers this item closed and the records will be reviewed during the next inspection."

AGREEMENT STATE REPORT - RADIATION TECHNICIAN POTENTIAL OVEREXPOSURE

The following information was obtained from the State of Florida via email:

"An employee of Cardinal Health had a dosimeter reading of 140 REM. The employee routinely wears one whole-body badge and two ring dosimeters assigned to him. These findings are for the wear period of 2/16/2015-3/1/2015. The whole body badge had a reported dose of 140884 mRem DDE and 241488 mRem SDE. [Cardinal Health] stated that the individual didn't have any reportable readings from their rings badges for this wear period. The individual is showing no symptoms of overexposure and has been removed from handling radioactive material as a safety precaution. It is believed that the badge may have become contaminated therefore distorting the correct exposure reading. Cardinal Health is reportedly conducting an investigation to find the cause and extent of this incident. Pending the Landauer report and some additional information, an investigator will be assigned to inspect their laboratory for safety and confirm Cardinal Health's investigative conclusions."

NextEra Energy DAEC [Duane Arnold Energy Center] took immediate action to restore the coating to within design parameters during the refueling outage and the degraded condition no longer exists. Extensive analysis was performed to determine effect of the delaminated material. Upon completion of this investigation, NextEra Energy DAEC has determined an unanalyzed condition existed as a result of the coating degradation and is reporting the condition under 10 CFR 50.72(b)(3)(ii)(B).

"A root cause evaluation has been performed to determine causes and corrective actions.

"The NRC Resident Inspector has been notified."
