SUMMARY OF FINDINGS

IR 05000397/2012007; 6/11/12 - 7/27/12; Energy Northwest; Columbia Generating Station; Triennial Fire Protection Team Inspection.

The report covered a two-week on-site triennial fire protection team inspection by specialist inspectors from Region IV. One Green finding, which was a non-cited violation (NCV), was identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, "Significance Determination Process." Findings for which the significance determination process (SDP) does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.

A. NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green.

The inspectors identified a non-cited violation for the failure to ensure that material, parts, and equipment specified met or exceeded the design criteria as required by License Condition 2.C.14, "Fire protection Program (Generic Letter 86-10)." Specifically, prior to implementing engineering change EC 9123, the licensee failed to analyze for all possible failure modes of fire induced circuit failures for transducers installed for ensuring electrical isolation in the event of a fire in the control room for post fire safe shutdown standby service water pump SW-P-1B, residual heat removal pump RHR-P-2B, and circuit breaker E-CB-B/8 as required by FSAR Appendix F, Table F.3-1.

The failure to analyze a modification to post fire safe shutdown circuitry for all possible modes of fire induced circuit failures was a performance deficiency. The performance deficiency was more than minor because it was associated with the protection against external events (fire) attribute of the Mitigating Systems Cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated this deficiency using Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance Determination Process." The performance deficiency affected the fire protection defense-in depth strategies involving post-fire safe shutdown systems.

This finding was evaluated using the process in Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance Determination Process," Attachment 2, "Degradation Rating Guidance Specific to Various Fire Protection Program Elements," and was determined to be of very low safety significance. The finding was assigned a low degradation rating because the capability to achieve safe shutdown in the event of a control room fire would be minimally impacted by the failure to analyze the control circuitry for equipment required for post fire safe shutdown. This was based on the licensee verifying through bench testing that the component in question does provide adequate electrical isolation. Because this finding had a low degradation rating, it screened as having very low safety significance (Green). The performance deficiency had a cross-cutting aspect in the area of human performance associated with decision making because the licensee did not make risk-significant decisions using a systematic process, especially when faced with uncertain or unexpected plant conditions, to ensure safety was maintained and failed to implement the roles and authorities as designed for risk-significant decisions H.1(a). (Section 1R05.06.b)

B. Licensee-Identified Violations

None.

REPORT DETAILS

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity

1R05 Fire Protection

This report presents the results of a triennial fire protection inspection conducted in accordance with NRC Inspection Procedure 71111.05T, "Fire Protection (Triennial)," at the Columbia Generating Station. The inspection team evaluated the implementation of the approved fire protection program in selected risk-significant areas, with an emphasis on the procedures, equipment, fire barriers, and systems that ensure the post-fire capability to safely shutdown the plant.

Inspection Procedure 71111.05T requires the selection of three to five fire areas for review. The inspection team used the fire hazards analysis section of the Columbia Generating Station Fire Probabilistic Safety Assessment to select the following five risk-significant fire areas (inspection samples) for review:

  • Fire Area RC-10 Control Room
  • Fire Area RC-14 Division 1 Switchgear Room
  • Fire Area TG-1, Fire Zone 12 Turbine Building South Corridors The inspection team evaluated the licensee's fire protection program using the applicable requirements, which included plant Technical Specifications, Operating License Condition 2.C.14, NRC safety evaluations, 10 CFR 50.48, and Branch Technical Position 9.5-1. The team also reviewed related documents that included the Final Safety Analysis Report (FSAR), Section 9.5; the fire hazards analysis; and the post-fire safe shutdown analysis.

Specific documents reviewed by the team are listed in the attachment. Three inspection samples were completed.

.01 Protection of Safe Shutdown Capabilities

a. Inspection Scope

The team reviewed piping and instrumentation diagrams, safe shutdown equipment list, safe shutdown design basis documents, and the post-fire safe shutdown analysis to verify that the licensee properly identified the components and systems necessary to achieve and maintain safe shutdown conditions for fires in the selected fire areas. The team observed walk-downs of the procedures used for achieving and maintaining safe shutdown in the event of a fire to verify that the procedures properly implemented the safe shutdown analysis provisions.

For each of the selected fire areas, the team reviewed the separation of redundant safe shutdown cables, equipment, and components located within the same fire area. The team also reviewed the licensee's method for meeting the requirements of 10 CFR 50.48; Branch Technical Position 9.5-1, Appendix A; and 10 CFR Part 50, Appendix R, Section III.G. Specifically, the team evaluated whether at least one post-fire safe shutdown success path remained free of fire damage in the event of a fire. In addition, the team verified that the licensee met applicable license commitments.

b. Findings

No findings were identified.

.02 Passive Fire Protection

a. Inspection Scope

The team walked down accessible portions of the selected fire areas to observe the material condition and configuration of the installed fire area boundaries (including walls, fire doors, and fire dampers) and verify that the electrical raceway fire barriers were appropriate for the fire hazards in the area. The team compared the installed configurations to the approved construction details, supporting fire tests, and applicable license commitments.

The team reviewed installation, repair, and qualification records for a sample of penetration seals to ensure the fill material possessed an appropriate fire rating and that the installation met the engineering design. The team also reviewed similar records for the rated fire wraps to ensure the material possessed an appropriate fire rating and that the installation met the engineering design.

b. Findings

No findings were identified.

.03 Active Fire Protection

a. Inspection Scope

The team reviewed the design, maintenance, testing, and operation of the fire detection and suppression systems in the selected fire areas. The team verified the automatic detection systems and the manual and automatic suppression systems were installed, tested, and maintained in accordance with the National Fire Protection Association code of record or approved deviations, and that each suppression system was appropriate for the hazards in the selected fire areas.

The team performed a walkdown of accessible portions of the detection and suppression systems in the selected fire areas. The team also performed a walkdown of major system support equipment in other areas (e.g., fire pumps and Halon supply systems) to assess the material condition of these systems and components.

The team reviewed the electric and diesel fire pump flow and pressure tests to verify that the pumps met their design requirements. The team also reviewed the halon suppression functional tests to verify that the system capability met the design requirements.

The team assessed the fire brigade capabilities by reviewing training, qualification, and drill critique records. The team also reviewed pre-fire plans and smoke removal plans for the selected fire areas to determine if appropriate information was provided to fire brigade members and plant operators to identify safe shutdown equipment and instrumentation, and to facilitate suppression of a fire that could impact post-fire safe shutdown capability. In addition, the team inspected fire brigade equipment to determine operational readiness for fire fighting.

The team observed an unannounced fire drill, conducted on June 27, 2012, in the Radwaste Building 487' Elevation General Area and the subsequent drill critique using the guidance contained in Inspection Procedure 71111.05AQ, "Fire Protection Annual/Quarterly." The team observed fire brigade members fight a simulated fire in the Radwaste Building, located in the radiological controlled area. The team verified that the licensee identified problems, openly discussed them in a self-critical manner at the drill debrief, and identified appropriate corrective actions. Specific attributes evaluated were:

(1) proper wearing of turnout gear and self-contained breathing apparatus;
(2) proper use and layout of fire hoses;
(3) employment of appropriate fire fighting techniques; (4)sufficient fire fighting equipment was brought to the scene;
(5) effectiveness of fire brigade leader communications, command, and control;
(6) search for victims and propagation of the fire into other areas;
(7) smoke removal operations;
(8) utilization of pre-planned strategies;
(9) adherence to the pre-planned drill scenario; and
(10) drill objectives.

b. Findings

No findings were identified.

.04 Protection From Damage From Fire Suppression Activities

a. Inspection Scope

The team performed plant walkdowns and document reviews to verify that redundant trains of systems required for safe shutdown, which are located in the same fire area, would not be subject to damage from fire suppression activities or from the rupture or inadvertent operation of fire suppression systems. Specifically, the team verified that:

  • A fire in one of the selected fire areas would not directly, through production of smoke, heat, or hot gases, cause activation of suppression systems that could potentially damage all redundant safe shutdown trains.
  • A fire in one of the selected fire areas or the inadvertent actuation or rupture of a fire suppression system would not directly cause damage to all redundant trains (e.g., sprinkler-caused flooding of other than the locally affected train).

Adequate drainage is provided in areas protected by water suppression systems.

b. Findings

No findings were identified.

.05 Alternative Shutdown Capability

a. Inspection Scope

Review of Methodology The team reviewed the safe shutdown analysis, operating procedures, piping and instrumentation drawings, electrical drawings, the Final Safety Analysis Report, and other supporting documents to verify that safe shutdown could be achieved and maintained from outside the control room for fires that require evacuation of the control room, with or without offsite power available.

Plant walkdowns were conducted to verify that the plant configuration was consistent with the description contained in the safe shutdown and fire hazards analysis. The team focused on ensuring the adequacy of systems selected for reactivity control, reactor coolant makeup, reactor decay heat removal, process monitoring instrumentation, and support system functions.

The team also verified that the systems and components credited for safe shutdown would remain free from fire damage. Finally, the team verified that the transfer of control from the control room to the alternative shutdown location would not be affected by fire induced circuit failures (e.g., by the provision of separate fuses and power supplies for alternative shutdown control circuits).

Review of Operational Implementation

The team verified that the licensed and non licensed operators received training on alternative shutdown procedures. The team also verified that sufficient personnel to perform a safe shutdown are trained and available onsite at all times, exclusive of those assigned as fire brigade members.

A simulated walkdown of the post-fire safe shutdown procedure with licensed and non licensed operators was performed to determine the adequacy of the procedure. The team observed that the procedure, as written, does ensure a safe shutdown condition of the plant and does implement the required actions within the time limits specified by analysis. Time critical actions that were observed include a reactor trip, closure of main steam isolation valves, isolating unprotected circuits, restoring electrical power, establishing control at the remote shutdown and local control panels, performing an emergency depressurization, establishing reactor coolant makeup at desired pressure, and establishing decay heat removal.

The team reviewed operator manual actions to ensure that they could be implemented in accordance with plant procedures in the time necessary to support safe shutdown for a fire in the control room. The team concluded that the licensee procedure does ensure safe shutdown of the plant.

The team also reviewed the periodic testing of the alternative shutdown transfer capability as well as instrumentation and control functions to verify that the tests are adequate to demonstrate the functionality of the alternative shutdown capability.

b. Findings

No findings were identified.

.06 Circuit Analysis

a. Inspection Scope

The team reviewed the post-fire safe shutdown analysis to verify that the licensee identified the circuits that may impact the ability to achieve and maintain safe shutdown.

The team verified, on a sample basis, that the licensee properly identified the cables for equipment required to achieve and maintain hot shutdown conditions in the event of a fire in the selected fire areas. The team verified that these cables were either adequately protected from the potentially adverse effects of fire damage or were analyzed to show that fire induced circuit faults (e.g., hot shorts, open circuits, and shorts to ground) would not prevent safe shutdown. The team reviewed the circuits associated with the following components:

  • E-CB-B/8, RHR-CB-P2B, SW-CB-P1B, CT Shorting Switch Modification
  • Whittaker Mineral Insulated Cables for Instrumentation and Control associated with Post Fire Safe Shutdown

For this sample, the team reviewed electrical elementary and block diagrams and identified power, control, and instrument cables necessary to support their operation. In addition, the team reviewed cable routing information to verify that fire protection features were in place as needed to satisfy the separation requirements specified in the fire protection license basis.

b. Findings

Introduction.

The team identified a violation of License Condition 2.C.14, "Fire protection Program (Generic Letter 86-10)" of very low safety significance (Green) for the failure to analyze for all possible modes of fire induced circuit failures introduced by a modification made to post fire safe shutdown circuitry. Specifically, the licensee failed to analyze for all possible failure modes for transducers required for ensuring electrical isolation in the event of a fire in the control room for standby service water pump SW-P-1B, residual heat removal pump RHR-P-2B, and circuit breaker E-CB-B/8. As a result, the licensee failed to ensure that the local control circuitry would be isolated from the effects of fire damage caused by a control room fire.

Description.

In the event of a fire in the control room, the licensee must ensure control circuitry for equipment credited for post fire safe shutdown is electrically isolated to ensure that fire damage would not prevent operation of equipment needed to achieve and maintain safe shutdown conditions. In June 2012, the licensee implemented engineering change EC 9123 to replace the isolation function of current transformer (CT) shorting switches. The shorting switches were replaced with current transducers to isolate control room ammeter circuitry from the control circuitry for service water pump 1B, residual heat removal pump 2B, and circuit breaker B/8 which connects offsite power to the credited class 1E 4160V SM8 bus.

The team reviewed the licensee's engineering change package and evaluations for the modification. The team identified that the evaluation did not contain any analysis of potential circuit failure modes for response of the transducers. The licensee failed to establish the criteria for determining if the component could be impacted by fire induced circuit failures prior to implementing the modification in the plant and issuing a new revision of procedure ABN-CR-EVAC "Control Room Evacuation and Remote Cooldown," Revision 023, which omitted using the manual switching of the CT shorting switches for isolation. In response to the identified deficiency, the licensee was able to implement compensatory measures to reinstate the use of the CT shorting switches which had been left in place, until bench testing on the component could be performed. The licensee entered this deficiency in their corrective action program as Condition Report 00266019.

Analysis.

The failure to analyze a modification to post fire safe shutdown circuitry for all possible modes of fire induced circuit failures was a performance deficiency. Specifically, the licensee failed to ensure that control circuitry for equipment required for post fire safe shutdown would be isolated from the control room in the event of a fire. The performance deficiency was more than minor because it was associated with the protection of external events attribute (fire) of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The team evaluated the finding using Inspection Manual Chapter 0609, Appendix F, "Fire Protection Significance Determination Process," because it affected fire protection defense in depth strategies involving post fire safe shutdown. Using Appendix F, Attachment 2, "Degradation Rating Guidance Specific to Various Fire Protection Program Elements," the team assigned a low degradation rating to the finding because the capability to achieve safe shutdown in the event of a control room fire would be minimally impacted by the failure to analyze the control circuitry for equipment required for post fire safe shutdown. This was based on the licensee verifying through bench testing that the component in question does provide adequate electrical isolation. Because this finding had a low degradation rating, it screened as having very low safety significance (Green). The performance deficiency had a cross-cutting aspect in the area of human performance associated with decision making because the licensee did not make risk-significant decisions using a systematic process, especially when faced with uncertain or unexpected plant conditions, to ensure safety was maintained and failed to implement the roles and authorities as designed for risk-significant decisions H.1(a).

Enforcement.

Fire Protection License Condition 2.C.14, "Fire protection Program (Generic Letter 86-10)," specifies that the licensee shall implement and maintain in effect all provisions of the approved Fire Protection Program. Final Safety Analysis Report, Table F.3-1, "Comparison with BTP 9.5-1 Appendix A," Section C, "Quality Assurance Program," requires in part, that "the established engineering procedures require the design changes to be reviewed by cognizant personnel to ensure material, parts, and equipment specified will meet or exceed the design criteria."

Contrary to the above, during a plant modification in June 2012, the licensee failed to review design changes to ensure material, parts, and equipment specified met or exceeded the design criteria. Specifically, the licensee failed to analyze all circuit failure modes for transducers installed in post fire safe shutdown circuitry to ensure electrical isolation for a control room fire. Because this finding is of very low safety significance and has been entered into the licensee's corrective action program (Condition Report 00266019), this violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000397/2012007-001, Failure to Analyze Post Fire Safe Shutdown Circuitry for Isolation for a Control Room Fire.

.07 Communications

a. Inspection Scope

The inspectors reviewed the adequacy of the communication system to support plant personnel in the performance of alternative post-fire safe shutdown functions and fire brigade duties. The review verified that the licensee established and maintained in working order primary and backup communications. Further, the inspectors evaluated the environmental impacts such as ambient noise levels, coverage patterns, and clarity of reception. The inspectors reviewed that the electrical power supplies, PBX battery system, PBX phones, sound powered phones and cable routing for the phone system would allow them to remain functional following a fire in the control room and other fire areas.

b. Findings

No findings were identified.

.08 Emergency Lighting

a. Inspection Scope

The inspectors reviewed the emergency lighting system required to support plant personnel in the performance of post-fire safe shutdown functions to verify it was adequate to support the performance of manual actions required to achieve and maintain safe shutdown conditions, and for illuminating access and egress routes to the areas where manual actions are required. The review verified that the licensee relied on fixed emergency lights with an 8-hour battery capacity, diesel backed fluorescent lights, and 8-hour portable lanterns for selected post-fire safe shutdown manual actions. The licensee maintained the emergency light batteries in accordance with manufacturer recommendations, and tested and performed maintenance in accordance with plant procedures and industry practices. The inspectors evaluated the locations and positioning of fixed emergency lights and the four pre-staged locations for the storage of the 8-hour portable lanterns (five 8-hour portable lanterns at each location) during a walkthrough of the control room evacuation procedure and during review of manual actions performed for fires in areas outside of the control room. The approved 8-hour portable lanterns are used exclusively for selected post-fire safe shutdown manual actions and there are adequate lanterns pre-staged at each of the four locations to supply the control room staff of five. The portable 8-hour lanterns are maintained and tested annually.

b. Findings

No findings were identified.

.09 Cold Shutdown Repairs

a. Inspection Scope

The team verified that the licensee does not perform or credit any repairs to achieve post-fire safe shutdown.

b. Findings

No findings were identified.

.10 Compensatory Measures

a. Inspection Scope

The team verified that compensatory measures were implemented for out-of-service, degraded, or inoperable fire protection and post-fire safe shutdown equipment, systems, or features (e.g., detection and suppression systems and equipment; passive fire barriers; or pumps, valves, or electrical devices providing safe shutdown functions). The team also verified that the short-term compensatory measures compensated for the degraded function or feature until appropriate corrective action could be taken and that the licensee was effective in returning the equipment to service in a reasonable period of time.

b. Findings

No findings were identified.

.11 B.5.b Inspection Activities

a. Inspection Scope

The inspectors reviewed the licensee's implementation of guidance and strategies intended to maintain or restore core, containment, and spent fuel pool cooling capabilities under the circumstances associated with loss of large areas of the plant due to explosions or fire as required by Section B.5.b of the Interim Compensatory Measures Order, EA-02-026, dated February 25, 2002, and 10 CFR 50.54(hh)(2).
