Dear Mr. Bement:
On February 15, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the Palo Verde Nuclear Generating Station, Units 1, 2, and 3 and discussed the results of this inspection with Ms. Maria Lacal, Senior Vice-President Regulatory and Oversight, and other members of your staff. The results of this inspection are documented in the enclosed report.

Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green Finding None 71111.05T-Systems FIN 05000528/2018012-01; Fire 05000529/2018012-01; Protection 05000530/2018012-01 (Triennial)
Closed The inspectors identified a Green finding for failure to provide adequate guidance to assure degraded or deficient emergency lighting required for post-fire safe shutdown is corrected in a timely manner. Specifically, the licensee failed to specify that failed Appendix R emergency lighting observed during operator rounds must be promptly reported to ensure the 30-day repair requirement can be met.
Description:
The licensee provides emergency lighting for access and egress paths, and to illuminate required safe shutdown components to safely shut down the reactor in case of fire requiring control room evacuation, in accordance with 10 CFR 50, Appendix R, Section III.J.,
Procedure 40DP-9ZZ16, Administrative Controls for Appendix R Equipment, Revision 13, Steps 4.5.1 and 4.6.1, limit the out-of-service time for Appendix R equipment and require restoring the equipment to service within 30 days. The licensee provides guidance to operations department watch standers to check for deficient lighting throughout the plant.
Procedure 40DP-9OP20, Watch Standing Practices, Revision 48, Step 4.3.1.1 instructs watch standers to check for adequate or sufficient lighting, among other items during routine tours of the plant.
On January 30, 2018, during the walkdown of the control room evacuation due to fire Procedure 40AO-9ZZ19, Control Room Fire, Revision 35, the inspectors identified multiple examples of Appendix R emergency light fixtures that were not functional. The licensee confirmed no condition report had documented these deficient emergency lights at that time.
During operator rounds through the area, with offsite power available, the area had adequate and sufficient lighting from the normal AC lighting system. The guidance provided in Procedure 40DP-9OP20 was not adequate to instruct watch standers to identify when an Appendix R emergency light is not functional and to promptly identify the failure to ensure timely restoration of the light.
Corrective Actions: The licensee documented the emergency light deficiencies in the corrective action program to initiate repairs, and also issued an Operations Communication Newsflash titled, Actions needed on Emergency (App R) Lighting, dated February 1, 2018.
The Newsflash required all operations crews to review procedures for identifying emergency lighting deficiencies and to focus on the emergency light fixtures. The licensee has 30 days to repair and restore the emergency lights to operation. The licensee has a standing compensatory measure for emergency lighting requiring operators to obtain flashlights from the emergency storage locker during a control room evacuation due to fire. The licensee initiated a revision request to provide additional guidance in Procedure 40DP-9OP20, concerning the Appendix R emergency lighting.
Corrective Action Reference(s): 18-01512, 18-01683, 18-01685, 18-01702, 18-01737
Performance Assessment:
Performance Deficiency: The Licensee failed to provide adequate guidance to personnel to assure degraded or deficient emergency lighting required for post-fire safe shutdown was corrected in a timely manner. The licensee failed to specify in Procedure 40DP-0OP20, Watch Standing Practices, that degraded or deficient Appendix R emergency lighting was to be promptly identified to ensure restoration within the licensees 30-day requirement.
Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the Protection Against External Factors (Fire) attribute of the Mitigating Systems cornerstone to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, emergency lighting is required for access and egress, and to illuminate safe shutdown equipment needed to bring the reactor to safe shutdown following a fire.
Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609, Appendix F, Fire Protection, dated September 20, 2013. The finding is associated with the Mitigating Systems cornerstone and screened to Green with Step 1.3.1 because the reactor is able to reach and maintain safe shutdown conditions because the operators are required to carry flashlights to accomplish the safe shutdown procedure.
Cross-cutting Aspect: No cross-cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.
Enforcement:
Inspectors did not identify a violation of regulatory requirements associated with this finding.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On February 15, 2018, the inspector presented the triennial fire protection inspection results to Ms. M. Lacal, Senior Vice-President Regulatory and Oversight, and other members of the licensee staff.
