Performance Deficiency: The licensees failure to provide a water flow alarm for a water-based suppression system was a performance deficiency.
Performance Deficiency: The licensees failure to provide a water flow alarm for a water-based suppression system was a performance deficiency.


Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors attribute of the Mitigating Systems cornerstone. Specifically, by not having fire water flow indication and alarm capabilities negatively impacts fire suppression capability thus impacting the mitigating systems cornerstone objective.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, by not having fire water flow indication and alarm capabilities negatively impacts fire suppression capability thus impacting the mitigating systems cornerstone objective.


Significance: The inspectors assessed the significance of the finding using Appendix F, Fire Protection and Post - Fire Safe Shutdown SDP. The team assessed the finding using NRC Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, and determined the Mitigating System cornerstone was degraded. The team further assessed the finding using NRC Inspection Manual Chapter 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, and determined the finding to be of very low safety significance (Green) based upon Step 1.4.2. A since the marginal code variant suppression system appeared to still protect the targets (such as cable raceways that contain cables critical for safe shutdown) in this fire area.

REISSUE - OCONEE NUCLEAR STATION, UNITS 1, 2, & 3 - TRIENNIAL FIRE PROTECTION INSPECTION REPORT 05000269/2019012 AND 05000270/2019012 AND 05000287/2019012

Dear Mr. Burchfield:

On June 7, 2019 the US Nuclear Regulatory Commission (NRC) issued the Triennial Fire Protection Inspection for the Oconee Nuclear Station, Units 1 and 2, ADAMS Accession Number ML19207A158. In reviewing this report, we identified administrative errors regarding the inspected samples. Specifically, that the Fire Protection Inspection Requirements (IP Section 02.01a) (4 Samples) and the Inspection Activities (IP Section 02.03) (1 Sample)

were not included in the report. We request that the cover letter and report be replaced with the Enclosures to this letter.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 Public inspection, exemptions, requests for withholding of the NRCs Agency Rules of Practice and Procedure, a copy of this letter will be available electronically for public inspection in the NRC Public Document Room, of the Publicly Available Records (PARS) component of NRCs ADAMS; accessible from the NRC Website at https://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Please contact me at 404-997-4521 with any questions you have regarding this letter.

Sincerely,

/RA/

INSPECTION RESULTS

Failure to Provide a Water Flow Alarm for a Fixed Suppression System as required by NFPA 805 Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None (NPP) 71111.05XT Systems NCV 05000287,05000269,05000270/20190 12-01 Open/Closed The NRC team identified a finding and associated non-cited violation (NCV) of very low significance (Green), for the licensees failure to provide a water flow alarm for a fixed suppression system, in accordance with NFPA 805, Sections 3.9.2 and 3.9.3.

Description:

To assess the NFPA 805, Section 3.9, Automatic and Manual Water-Based Fire Suppression Systems requirements, the team reviewed the licensees license amendment request (LAR) submittal, dated April 14, 2010. In the referenced section, the licensee committed to meeting the NFPA 805, Section 3.9.2 and NFPA 3.9.3 requirements. In this instance, during the inspection and review of the fire areas for the 2019 Oconee TFPI the NRC identified the licensee was not in compliance with the stated commitment for the AB-105, Unit 2, Cable Room as specified and consistent with their stated commitment in their license amendment request (LAR), Attachment A - NEI 04-02 Table B-1 Transition of Fundamental FP Program & Design Elements. Initial questions related to the requirement arose based upon the review of fire area AB-092, Unit 2 Equipment Room. Based upon information reviewed, the NRC understood compliance to be consistent with the requirement and stated as such in the NFPA 805 Safety Evaluation Report (SER), dated December 29, 2010. Specifically, Attachment A, NFPA 805, Chapter 3, Fundamental Elements Compliance Matrix, Table 3.1-1 NFPA 805, Chapter 3, Fundamental Elements Compliance Matrix, Element 3.9.2 stated the licensee complied with the stated commitment which the NRC accepted. In part, the requirement stated that each system shall be equipped with a water flow alarm consistent with NFPA 805, Section 3.9.2 and all alarms from fire suppression systems shall annunciate in the control room or other suitable constantly attended location. The team determined that at this time, there are no flow alarms or indication from the fire suppression system serving fire area AB-105. To support the basis of why the suppression systems are credited, the team reviewed OSC-9314, Fire Risk Evaluation, Rev.

3, Section 1.2.3, Fixed Suppression. This section stated in part that suppression was required to suppress a fire in FA AB-105. The team reviewed the December 22, 2010 update to the LAR for FA AB-105 and concluded that suppression was required to support transition of an Existing Engineering Equivalency Evaluation (EEEE). Consistent with NFPA 805, Section A.2.2.7, the EEEE signifies that a generic letter (GL) 86-10 evaluation was performed prior to the transition to the NFPA 805 licensing basis to signify a noncompliance with the fire protection program requirements.

The inspection revealed that commitments to the NFPA 805, Section 3.9.2 and 3.9.3 requirements were also specified by the licensee in OM 280.0023.001, Fire Protection Design Basis Document OSS-0254.00-00-00-4008, Appendices A, B, & G. In Appendix A, NFPA 805 Ch 3 Compliance (NEI 04-02 Table B-1) the licensee stated that they complied with the NFPA 805 requirement to have water flow alarms on all required fixed extinguishing systems (3.9.2 of Appendix A) and they would ensure all alarms from the fire suppression system annunciate in the control room or other suitable location (OSS-0254.00-00-4008, Rev.

20 [Sec. 3.3.1.1.3] - Fire Protection Design Basis Document).

This licensing commitment was also in conflict with the conclusion reached in calculation OSC-8003, the NFPA 13 code compliance calculation for the U2 Cable Room's suppression system. Calculations OSC-8830 and OSC-8834, which were the NFPA 13 code compliance calculations for U1 and U3 Cable Rooms' suppression systems, acknowledged the water flow alarm does not exist.

The referenced calculations were inconsistent with the LAR dated December 22, 2010 and the SER. These attributes had implications on the selected license commitment (SLC) 16.9.2, Sprinkler and Spray Systems, which provided the applicable compensatory measures for a system if it became non-functional. Among the elements referenced in OSS 0254.00-00-4008, Oconee Fire Protection Design Basis Specification for Fire Protection Program, was compliance with NFPA 13. The team reviewed OSC-9375, Oconee Fire PRA, Fire Scenario Report, Rev. 7, which specified the importance of the suppression system as its applicably to fire areas based upon the formulation of a hot gas layer (HGL). This also provided the basis for suppression in the respective areas, which included AB-092 and AB-105. According to Appendix C, the HGL ZOI impact times for the Equipment and Cable Rooms ranged from 33 to 53 minutes. Additionally, FAs AB-089, AB-095, AB-101, and AB-106 also utilized the manually operated supply valves located at least 12 feet from the floor which without water flow indication and alarms this could adversely impact fire suppression activities.

Finally, the team reviewed OSC-9887, NFPA-805 Monitoring Program Scoping, Rev. 5 which stated in section 6.3, PMG component list for Manual Suppression, valves in the section were required by either fire risk evaluation (FRE) or multi-compartment analysis (MCA). In this instance, the team concluded the established functional failure criteria for Manual suppression was based upon the failure of the manual suppression system control valve to not function as designed which would only be revealed by compliance with the NFPA 805, Section 3.9.2 and 3.9.3 requirements (i.e. no flow no alarm or indication) upon actuation. The monitoring program requirements are based upon NFPA 805, Section 2.6 which states in part that the monitoring program ensures the availability and reliability of the fire protection systems are features are maintained consistent with the established performance criteria.

Following inspector questioning, the licensee provided a white paper that acknowledged the noncompliance which was inconsistent with what is required by the SER.

Corrective Action References: NCR 02274272

Performance Assessment:

Performance Deficiency: The licensees failure to provide a water flow alarm for a water-based suppression system was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, by not having fire water flow indication and alarm capabilities negatively impacts fire suppression capability thus impacting the mitigating systems cornerstone objective.

Significance: The inspectors assessed the significance of the finding using Appendix F, Fire Protection and Post - Fire Safe Shutdown SDP. The team assessed the finding using NRC Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, and determined the Mitigating System cornerstone was degraded. The team further assessed the finding using NRC Inspection Manual Chapter 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, and determined the finding to be of very low safety significance (Green) based upon Step 1.4.2. A since the marginal code variant suppression system appeared to still protect the targets (such as cable raceways that contain cables critical for safe shutdown) in this fire area.

Cross-Cutting Aspect: Not Present Performance. No cross cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.

Enforcement:

Violation: Oconee Nuclear Station Units 1, 2, and 3 Renewed Facility Operating License Condition 3.D required the licensee to implement and maintain in effect all provisions of the approved FPP that complied with 10 CFR 50.48 (c), National Fire Protection Association Standard NFPA 805, as specified in the NRC safety evaluation report (SER) dated December 29, 2010. Section 3.9.2 of NFPA 805 stated that each system shall be equipped with a water flow alarm. Section 3.9.3 stated that all alarms from fire suppression systems shall annunciate in the control room or other suitable constantly attended location.

Contrary to the above, from December 29, 2010 on as required by the SER, the licensee failed to equip the water-based suppression system in fire area AB-105 with a water flow alarm. Additionally, the licensee failed to assure that alarms from the water-based suppression system would annunciate in the control room or other suitable constantly attended location.

Enforcement Action: This violation is being treated as an non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
