COLUMBIA GENERATING STATION - NRC INTEGRATED INSPECTION REPORT 05000397/2018004

Dear Mr. Sawatzke:

On December 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Columbia Generating Station. On January 10, 2019, the NRC inspectors discussed the results of this inspection with Mr. W. Grover Hettel, Chief Nuclear Officer/Vice President Nuclear Generation, and other members of your staff. The results of this inspection are documented in the enclosed report.

NRC inspectors documented two findings of very low safety significance (Green) in this report.

One of these findings involved a violation of NRC requirements. The NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2 of the Enforcement Policy.

If you contest the violation or significance of the NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; the Director, Office of Enforcement; and the NRC resident inspector at the Columbia Generating Station.

If you disagree with a cross-cutting aspect assignment or a finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region IV; and the NRC resident inspector at the Columbia Generating Station. This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Columbia Generating Station in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information. NRC-identified and self-revealed findings, violations, and additional items are summarized in the tables below.

List of Findings and Violations Licensed Operator Failure Rate Cornerstone Significance Cross-cutting Inspection Aspect Procedure Mitigating Green H.1 - 71111.11 Systems FIN 05000397/2018004-01 Resources Closed The inspectors reviewed a self-revealed, Green finding associated with licensed operator performance on the biennial requalification exam. Specifically, 15 of 51 operators failed at least one portion of the biennial requalification examinations and 2 of 8 crews failed the simulator scenarios. Based on the licensee's successful remediation and subsequent retesting of individuals who failed a portion of the biennial requalification examination prior to returning to shift, no violation of regulatory requirements occurred.

Failure to Perform Hourly Fire Tours as Required by the Fire Protection Program Cornerstone Significance Cross-cutting Inspection Aspect Procedure Mitigating Green H.4 - 71152 Systems NCV 05000397/2018004-02 Teamwork Closed The inspectors identified a Green, non-cited violation of Columbia Generating Station Operating License Condition 2.C(14), Fire Protection Program (Generic Letter 86-10),

because the licensee failed to perform hourly compensatory fire tours as required by the Licensee Controlled Specifications (LCS). Specifically, while the essential fire detection for the residual heat removal 2B pump room was out of service, the licensee did not conduct an hourly fire tour of the residual heat removal 2B pump room area.

PLANT STATUS

The plant began the inspection period at 100 percent rated thermal power.

On December 6, 2018, condensate booster pump 2A tripped due to low section pressure.

Reactor feedwater pump 1B tripped due to the condensate booster pump 2A trip and caused a recirculation pump runback to 69 percent power. On December 7, 2018, operators returned reactor feedwater pump 1B and condensate booster pump 2A to service and restored power to 74 percent. On December 11, 2018, power ascension to 85 percent power was halted at 77 percent power due to a lockup of the rod drive control system. On December 12, 2018, the licensee increased reactor power to 92 percent by increasing recirculation flow. The unit was returned to rated thermal power on December 13, 2018.

On December 15, 2018, the unit was down powered to 62 percent to perform control rod sequence exchanges, turbine valve testing, and planned repairs to condensate booster pump 2B. The unit was returned to rated thermal power on December 16, 2018.

On December 23, 2018, the unit was down powered to 98 percent to perform main steam bypass valve testing. The unit was returned to rated thermal power on December 23, 2018, and remained at or near rated thermal power for the remainder of the inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in IMC 2515 Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem Identification and Resolution. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

INSPECTION RESULTS

Observation 71152 The inspectors performed an in-depth review of the licensees evaluation and corrective actions related to a potential trend in missed fire tours. Since July 1, 2018, the licensee initiated four Action Requests documenting missed fire tours: Action Requests 382646, 383676, 384338, and 385266. Three of the missed fire tours were of minor significance; however, one fire tour was of more than minor significance and is documented in this report as NCV 05000397/2018004-02, Failure to Perform Hourly Fire Tours as Required by the Fire Protection Program.

The inspectors assessed the licensees problem identification threshold, evaluations, and corrective actions and noted that the licensee appropriately considered extent of condition and extent of cause for the planned corrective action assignments. The inspectors determined the cause of each missed fire tour was unique and not indicative of a negative trend.

Unresolved Item Unresolved Discrepancies in the Licensing Basis of the 71152 (Closed) Tower Makeup System 05000397/2014002-02

Description:

This item was opened to review the adequacy of several changes the licensee made to the Columbia Generating Station Final Safety Analysis Report that redefined the role of the tower makeup (TMU) system as the ultimate heat sink following a design-basis tornado and changed the system description from safety-related to nonsafety-related. Additional inspection was required to determine whether the licensee made the subject changes in full compliance with 10 CFR 50.59. By memorandum, dated November 10, 2014 (ADAMS Accession No. ML14316A634), the U.S. Nuclear Regulatory Commission Region IV, Division of Reactor Projects, requested assistance from the NRC Office of Nuclear Reactor Regulation (NRR) to conduct a technical assessment of the Columbia Generating Station design and licensing bases for the TMU system.

Corrective Action Reference(s): Action Requests 302227, 304186, 308224, 312331, 346049 Closure Basis: The inspectors did not identify any findings during the follow-up inspection of this Unresolved Item. In a letter, dated October 17, 2018 (ADAMS Accession No. ML15191A2891), the NRR staff concluded that the TMU system is not part of the ultimate heat sink complex and that the requirement of Technical Specification 3.7.1, Standby Service Water (SW) System and Ultimate Heat Sink (UHS), is not applicable to the TMU system.

The NRR staff also concluded that the TMU system piping and components were not designated as Safety Class components and are not subject to the quality assurance requirements pursuant to Appendix B to Part 50 of Title 10 of the Code of Federal Regulations. This Unresolved Item is closed.

Licensed Operator Failure Rate Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green H.1 - 71111.11 Systems FIN 05000397/2018004-01 Resources Closed The inspectors reviewed a self-revealed, Green finding associated with licensed operator performance on the biennial requalification exam. Specifically, 15 of 51 operators failed at least one portion of the biennial requalification examinations, and 2 of 8 crews failed the simulator scenarios. Based on the licensee's successful remediation and subsequent retesting of individuals who failed a portion of the biennial requalification examination prior to returning to shift, no violation of regulatory requirements occurred.

Description:

During the facility-administered biennial requalification examination of licensed operators, the licensee training staff evaluated crew performance during dynamic simulator scenarios and individual operator performance during job performance measures and on the biennial written examination. Facility results of the biennial requalification examination showed that 15 of 51 licensed operators (29.4 percent) failed at least one portion of the biennial requalification examination and 2 of 8 crews (25 percent) failed the simulator scenarios, exceeding the threshold failure rate of 20 percent.

Corrective Actions: All individual and crew failures will be remediated and retested prior to performing licensed operator activities; and the licensee will perform an organizational and programmatic investigation (similar to a root cause investigation).

Corrective Action Reference: Action Request 387428

Performance Assessment:

Performance Deficiency: The inspectors determined that the high rate of licensed operator examination failures constituted a performance deficiency because licensed operators are expected to operate the plant within acceptable standards of knowledge and abilities demonstrated through periodic testing as required by 10 CFR 55.59(a)(2).

Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the human performance attribute of Mitigating Systems cornerstone. Specifically, 15 of 51 licensed operators and 2 of 8 crews, failed to demonstrate a satisfactory understanding of the required knowledge and abilities required to safely operate the facility under normal, abnormal, and emergency conditions.

Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609, Appendix I, "Licensed Operator Requalification Human Performance Significance Determination Process," dated December 6, 2011. This finding was of very low safety significance (Green) because the finding was related to the requalification exam results with a failure rate greater than 20 percent, but less than 40 percent.

Cross-cutting Aspect: This finding has a cross-cutting aspect in the area of human performance associated with resources, because the licensee failed to ensure that personnel were adequately trained to assure nuclear safety. Specifically, the licensee failed to use sufficiently challenging training evolutions during the training cycle to train and assess licensed operator knowledge [H.1].

Enforcement:

This finding does not involve enforcement action because no violation of regulatory requirements was identified.

Failure to Perform Hourly Fire Tours as Required by the Fire Protection Program Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green H.4 - 71152 Systems NCV 05000397/2018004-02 Teamwork Closed The inspectors identified a Green, non-cited violation of Columbia Generating Station Operating License Condition 2.C(14), Fire Protection Program (Generic Letter 86-10),because the licensee failed to perform hourly compensatory fire tours as required by the LCS.

Specifically, while the essential fire detection for the residual heat removal 2B pump room was out of service, the licensee did not conduct an hourly fire tour of the residual heat removal 2B pump room area.

Description:

The Columbia Fire Protection Plan is the combination of Final Safety Analysis Report, Appendix F, and Procedure SWP-FPP-01, Nuclear Fire Protection Program, Revision 8.

Step 3.6.5 of Procedure SWP-FPP-01 states, in part, that an hourly fire tour is a common compensatory measure for impaired fire systems and identifies fire hazards and incipient fire/smokeand that a fire tour is performed in accordance with LCS 1.10, Plant Procedure Manual PPM 1.3.10B, PPM 1.3.57, and Fire Protection Program Procedure Manual FPP 1.7.

Licensee Controlled Specification 1.10.6, Essential Fire Detection, Revision 73, Table 1.10.6-1, Area and Equipment Protected by Essential Fire Detection, lists the residual heat removal (RHR) 2B pump room as an area protected by essential fire detection that requires an hourly fire tour when the essential fire detection is inoperable.

On September 4, 2018, Fire Panel FP-CP-FCP1 was taken out of service for replacement per Work Order 02088112. The licensee activated fire protection system impairment (FPSI) 17-0367 and established an hourly fire tour of the affected areas in accordance with LCS 1.10.6, Essential Fire Detection, Revision 73, action statements A.1 and A.2, respectively. The work affected detection zone 13 which, per Table 1.10.6-1, Area and Equipment Protected by Essential Fire Detection, Revision 73, included the residual heat removal 2A pump room, residual heat removal 2B pump room, residual heat removal 2C pump room, and the reactor core isolation cooling pump room, among others.

Security officers perform the hourly fire tours in accordance with Procedure SFI-26, Fire Tour, Revision 2. Step 4.3.7.b of Procedure SFI-26 states to complete and follow the Fire Tour Log as published, starting at the beginning of the first page. From September 4-6, 2018, the fire log listed [RB] 422 All Rooms and 441 Truck Bay, which included the residual heat removal 2B pump room. At the time of the required tours, the residual heat removal room 2B pump room was posted as a contaminated and high radiation area. Per plant procedures, entering a contaminated area and/or high radiation area during a fire tour is outside the scope for security personnel and as such, the security officers did not enter the residual heat removal 2B pump room as required. This was confirmed through interviews with plant personnel.

Multiple work groups are responsible for implementing the Columbia Fire Protection Plan when a fire protection system is impaired. Fire Protection personnel create the fire protection system impairments. Security personnel conduct the fire tours while Operations personnel provide oversight and ensure compliance with LCS 1.10.6. Meanwhile, radiation protection personnel maintain high radiation area, radiation area, and contamination area boundaries.

Communication between the work groups is essential to ensure that the fire tours are conducted in accordance with the fire protection system impairment while following radiation protection guidelines.

Corrective Actions: The licensees corrective actions included restoring functionality of the essential fire detection for the residual heat removal system 2B pump room by completing the maintenance on Fire Panel FP-CP-FCP1 and performing an apparent cause evaluation to identify the cause of the performance deficiency and implement further corrective actions.

Corrective Action Reference: Action Request 384338.

Performance Assessment:

Performance Deficiency: The failure to perform hourly compensatory fire tours in accordance with the LCS while a fire barrier component was out of service was a performance deficiency.

Screening: The performance deficiency was more than minor, and therefore a finding, because it was associated with the protection against external factors (i.e. internal fire)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 (i.e., core damage). Specifically, while the essential fire detection for the residual heat removal 2B pump room was out of service, the licensee did not conduct a compensatory hourly fire tour of the residual heat removal 2B pump room area for a period of approximately 2 days. Not performing these tours led to a condition where a fire in the residual heat removal pump 2B room would go unrecognized for a longer than anticipated period of time leading to increased fire risk to safety related components and systems.

Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, and Appendix F, Fire Protection Significance Determination Process, dated May 2, 2018. The inspectors assigned the finding to Fire Finding Category 1.4.2 using Inspection Manual Chapter 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, dated May 2, 2018, because the finding involved a fire watch posted as a compensatory measure for a fixed fire protection system outage or degradation. The inspectors assigned the finding a high degradation rating using Inspection Manual Chapter 0609, Appendix F, 2, Degradation Rating Guidance, dated May 2, 2018, because the smoke detectors and fire panel annunciator for the affected room were nonfunctional during the panel replacement. Further, the inspectors determined a Phase 2 evaluation was required because the non-functional detection system adversely affected the ability of the system to protect equipment important to safe shutdown and the licensee did not have a fire PRA

[probabilistic risk assessment] capable of adequately evaluating the risk associated with the finding.

The senior reactor analyst performed a bounding risk evaluation for the performance deficiency and determined that the finding was of very low safety significance (Green). In the Washington Public Power Supply System Individual Plant Examination of External Events for the Washington Nuclear Plant 2, Revision 0, dated June 1995, Fire Zone R-4, RHR-B Room, was assigned a fire initiating event frequency of 5.0E-03/ year. The resulting baseline core damage frequency was calculated to be 2.57E-07. The performance deficiency existed for 2 days, from September 4 through 6, 2018. Applying the 2-day exposure period (5.48E-03), the resulting probability of a fire starting in the room over this period was calculated to be 2.74E-05. Because at least two trains of a multi-train injection system would be available following a postulated fire, the analyst assigned a bounding failure rate for a single multi-train system. Using Table 5, Mitigation Capability Credits for Installed Equipment, from Inspection Manual Chapter 0609, Appendix G, Attachment 3, Phase 2 Significance Determination Process Template for BWR during Shutdown, dated February 28, 2005, as best available information, the analyst assigned 1.0E-3 as the failure of the safe shutdown path failure probability. Therefore, the external events incremental conditional core damage probability from internal fire was 8.22E-08. The dominant sequence was a fire in the RHR-B Pump Room leading to a reactor trip followed by a failure of the following functions:

• main feedwater;

• high pressure core spray;

• reactor isolation core cooling;

• low pressure injection;

• condensate; and

• alternate low pressure injection.

Because this core damage frequency is below the green/white threshold for large, early release frequency, no additional evaluation was necessary to determine that the finding was of very low safety significance with respect to containment failures.

Cross-cutting Aspect: This finding had a cross-cutting aspect in the area of human performance, teamwork, in that the licensee individuals and work groups failed to communicate and coordinate their activities within and across organizational boundaries to ensure nuclear safety was maintained. Specifically, there was a lack of communication between the operations, radiation protection, fire protection, and security work groups when implementing FPSI 17-0367 [H.4].

Enforcement:

Violation: Columbia Generating Station License Condition 2.C(14), Fire Protection Program (Generic Letter 86-10), requires, in part, that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in Section 9.5.1 and Appendix F of the Final Safety Analysis Report (FSAR) for the facility through Amendment

1. 39 and as described in subsequent letters to the staff referenced in the May 22, 1989, safety evaluation and as approved in the Safety Evaluation Report issued in March 1982, and subsequent supplements and safety evaluations. The Columbia Fire Protection Plan is the combination of Final Safety Analysis Report Appendix F and Procedure SWP-FPP-01, Nuclear Fire Protection Program, Revision 8. Step 3.6.5 of Procedure SWP-FPP-01 states, in part, that an hourly fire tour is a common compensatory measure for impaired fire systems and identifies fire hazards and incipient fire/smokeand that a fire tour is performed in accordance with LCS 1.10, Plant Procedure Manual PPM 1.3.10B, PPM 1.3.57, and Fire Protection Program Procedure Manual FPP 1.7. Licensee Controlled Specification 1.10.6, Essential Fire Detection, Revision 73, Table 1.10.6-1, Area and Equipment Protected by Essential Fire Detection, lists the residual heat removal 2B pump room as an area protected by essential fire detection that requires an hourly fire tour when the essential fire detection is inoperable. FPSI 17-0367 established an hourly fire tour of the affected areas in accordance with LCS 1.10.6. The work affected detection zone 13 which, per Table 1.10.6-1, Area and Equipment Protected by Essential Fire Detection, Revision 73, included the residual heat removal 2A pump room, residual heat removal 2B pump room, residual heat removal 2C pump room, and the reactor core isolation cooling pump room, among others. Security officers perform the hourly fire tours in accordance with Procedure SFI-26, Fire Tour, Revision 2. Step 4.3.7.b of Procedure SFI-26 states to complete and follow the Fire Tour Log as published, starting at the beginning of the first page. From September 4-6, 2018, the fire log listed [RB] 422 All Rooms and 441 Truck Bay which included the residual heat removal 2B pump room.

Contrary to the above, from September 4-6, 2018, the licensee failed to implement all provisions of the approved fire protection program as described in Section 9.5.1 and Appendix F of the Final Safety Analysis Report (FSAR) for the facility through Amendment

1. 39 and as described in subsequent letters to the staff referenced in the May 22, 1989, safety evaluation and as approved in the Safety Evaluation Report issued in March 1982, and subsequent supplements and safety evaluations. Specifically, while the essential fire detection for the residual heat removal 2B pump room was out of service, the licensee did not conduct an hourly fire tour of the residual heat removal 2B pump room area for a period of approximately 2 days.

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