SUBJECT:
D.C. COOK NUCLEAR POWER PLANT, UNITS 1 AND 2 NRC INSPECTION REPORT 50-315/03-05; 50-316/03-05
Dear Mr. Bakken:
On April 11, 2003, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your D.C. Cook Nuclear Power Plant facility. The enclosed report documents the inspection findings which were preliminarily discussed on April 11, 2003 with you and members of your staff.
The inspection examined the effectiveness of activities conducted under your license as they related to the implementation of your NRC approved Fire Protection Program. The inspection consisted of a selected examination of design drawings, calculations, analyses, procedures, audits, field walkdowns, and interviews with personnel.
Based on the results of this inspection, there were four NRC-identified findings of very low safety significance which involved violations of NRC requirements. However, because these violations were non-willful and non-repetitive and because they were entered into your corrective action program, the NRC is treating these findings as Non-Cited Violations, in accordance with Section VI.A.1 of the NRCs Enforcement Policy. We note that your staff had previously identified issues which should have resulted in three of the four violations being addressed. However, your staff did not properly resolve the identified issues in these three cases.
If you contest the subject or severity of a Non-Cited Violation, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region III; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the D.C. Cook Nuclear Power Plant facility. In accordance with 10 CFR 2.790 of the NRCs "Rules of Practice," a copy of this letter, its enclosure, and your responses will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/

SUMMARY OF FINDINGS
IR 05000315-03-05; 05000316-03-05; Indiana Michigan Power Company; 03/24/03-04/11/03;
D.C. Cook Nuclear Power Plant, Units 1 and 2; Fire Protection Triennial.
This report covers an announced baseline triennial fire protection inspection. The inspection was conducted by three Region III inspectors. Four Green findings associated with four Non-Cited Violations were identified. The significance of most findings is indicated by their color (Green,
White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.
A. Inspector-Identified and Self-Revealed Findings
Cornerstone: Mitigating Systems
- Green.
A finding of very low safety significance was identified by the inspectors in that the control room heating, ventilation, and air conditioning (HVAC) system would be damaged for a postulated fire in fire zone 41. The cause of this finding was related to the cross-cutting area of Problem Identification and Resolution. Despite previously identifying this issue, the licensee failed to properly address this issue in that they mistakenly believed that performing a repair to the control room HVAC system in the event of a fire would meet regulatory requirements.
This finding was more than minor because one train of systems (i.e., control room HVAC) necessary to achieve and maintain hot shutdown conditions would not be free of fire damage for a postulated fire. The finding was of very low safety significance because actions to repair the control room HVAC system were proceduralized and provisions for providing temporary ventilation existed. This issue was a violation of 10 CFR 50.48 and 10 CFR Part 50, Appendix R, Section III.G.1 which required that one train of systems necessary to achieve and maintain hot shutdown conditions be free of fire damage (Section 1R05.2b).
- Green.
A finding of very low safety significance was identified by the inspectors in that the licensee failed to ensure that alternative shutdown capability for a fire area could accommodate post-fire conditions where off-site power would not be available.
Specifically, for a postulated fire in fire zone 41, onsite power (i.e., emergency diesel generators) may not be available due to fire damage.
This finding was more than minor because alternative shutdown capability was not assured for when off-site power would not be available. The finding was of very low safety significance because off-site power would not be affected by a fire in fire zone 41.
This issue was a violation of 10 CFR 50.48 and 10 CFR Part 50, Appendix R, Section III.L.3 which required alternative shutdown capability to accommodate post-fire conditions where off-site power is available and where off-site power is not available for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> (Section 1R05.4b).
- Green.
A finding of very low safety significance was identified by the inspectors in that the licensee had failed to ensure that there was adequate emergency lighting (i.e., in the shift managers office) for required safe shutdown actions (i.e., the retrieval of safe shutdown emergency procedures and equipment). The cause of this finding was related to the cross-cutting area of Problem Identification and Resolution. Despite previously identifying this issue, the licensee failed to properly address this issue in that they mistakenly believed that the shift managers office was not a safe shutdown pathway.
This finding was more than minor because the lack of emergency lighting could result in delay of accomplishing safe shutdown actions. The finding was of very low safety significance because of the availability of portable head lamps. This issue was a violation of 10 CFR 50.48 and 10 CFR Part 50, Appendix R, Section III.J which required that emergency lighting units with at least an 8-hour battery power supply be provided in all areas needed for operation of safe shutdown equipment and in access and egress routes thereto (Section 1R05.7b).
- Green.
A finding of very low safety significance was identified by the inspectors in that the licensee had failed to ensure that minimum required carbon dioxide (CO2) system concentrations would be achieved for two fire zones. The cause of this finding was related to the cross-cutting area of Problem Identification and Resolution. Despite previously identifying this issue, the licensee failed to properly address this issue because they failed to address non-compliance with the applicable National Fire Protection Association (NFPA) code.
This finding was more than minor because a fire protection feature (i.e., a fixed suppression system) was adversely affected. The finding was of very low safety significance because of remaining available mitigation capability. This issue was a violation of a license condition which, by reference, invoked the applicable NFPA code which required a minimum CO2 concentration (Section 1R05.10b).
REPORT DETAILS
Summary of Plant Status: Both units were operated at or near full power during the inspection period.
REACTOR SAFETY
Cornerstones: Initiating Events and Mitigating Systems
1R05 Fire Protection
The purpose of this inspection was to review the D.C. Cook Nuclear Power Plant fire protection program for selected risk-significant fire areas. Emphasis was placed on verifying that the post-fire safe shutdown capability and the fire protection features were maintained free of fire damage to ensure that at least one post-fire safe shutdown success path was available. The inspection was performed in accordance with the NRC regulatory oversight process using a risk-informed approach for selecting the fire areas and attributes to be inspected. The lead inspector used the D.C. Cook Nuclear Power Plant Individual Plant Examination for External Events to choose several risk-significant areas for detailed inspection and review. The fire areas and zones chosen for review during this inspection were:
Fire Zone Description of Fire Area Reviewed Engineered Safety System and Motor Control Center Room, Unit 1 Unit 1 Control Room Unit 1 Control Room Cable Vault The primary focus for this inspection was on the safe shutdown procedures and safe shutdown methodology for the selected fire areas. The determination of license commitments and changes to the fire protection program were reviewed for the selected fire zones.
.1 Systems Required to Achieve and Maintain Post-Fire Safe Shutdown
Title 10 CFR Part 50, Appendix R, Section III.G.1, required the licensee to provide fire protection features that were capable of limiting fire damage to structures, systems, and components important to safe shutdown. The structures, systems, and components that were necessary to achieve and maintain post-fire safe shutdown were required to be protected by fire protection features that were capable of limiting fire damage to the structures, systems, and components so that:
- One train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergency control station(s) was free of fire damage; and
- Systems necessary to achieve and maintain cold shutdown from either the control room or emergency control station(s) could be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Specific design features for ensuring this capability were specified by 10 CFR Part 50, Appendix R, Section III.G.2.
a. Inspection Scope
The inspectors reviewed the plant systems required to achieve and maintain post-fire safe shutdown to determine if the licensee had properly identified the components and systems necessary to achieve and maintain safe shutdown conditions for each fire zone selected for review. Specifically, the review was performed to determine the adequacy of the systems selected for reactivity control, reactor coolant makeup, reactor heat removal, process monitoring, and support system functions. This review included the fire protection safe shutdown analysis.
The inspectors also reviewed the operators ability to perform the necessary manual actions for achieving safe shutdown including a review of procedures, accessibility of safe shutdown equipment, and the available time for performing the actions.
The inspectors reviewed the updated final safety analysis report and the licensees engineering and/or licensing justifications (e.g., NRC guidance documents, license amendments, technical specifications, safety evaluation reports, exemptions, and deviations) to determine the licensing basis.
b. Findings
No findings of significance were identified.
.2 Fire Protection of Safe Shutdown Capability
Title 10 CFR Part 50, Appendix R, Section III.G.2, required separation of cables and equipment and associated circuits of redundant trains by a fire barrier having a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> rating. If the requirements cannot be met, then alternative or dedicated shutdown capability and its associated circuits, independent of cables, systems or components in the area, room, or zone under consideration should be provided (Section III. G.3).
a. Inspection Scope
For each of the selected fire areas, the inspectors reviewed the licensees safe shutdown analysis to ensure that at least one post-fire safe shutdown success path was available in the event of a fire. This included a review of manual actions required to achieve and maintain hot shutdown conditions and make the necessary repairs to reach cold shutdown within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The inspectors also reviewed procedures to verify that adequate direction was provided to operators to perform these manual actions. Factors, such as timing, access to the equipment, and the availability of procedures, were considered in the review.
The inspectors also evaluated the adequacy of fire suppression and detection systems, fire area barriers, penetration seals, and fire doors to ensure that at least one train of safe shutdown equipment was free of fire damage. To accomplish this, the inspectors observed the material condition and configuration of the installed fire detection and suppression systems, fire barriers, and construction details and supporting fire tests for the installed fire barriers. In addition, the inspectors reviewed license documentation, such as deviations, detector placement drawings, fire hose station drawings, carbon dioxide pre-operational test reports, smoke removal plans, fire hazard analysis reports, safe shutdown analyses, and National Fire Protection Association (NFPA) codes to verify that the fire barrier installations met license commitments.
b. Findings
Introduction:
The inspectors identified that the licensee failed to ensure that one train of equipment necessary for safe shutdown would be free of fire damage. This issue was determined to be of very low safety significance and was dispositioned as a Green Non-Cited Violation (NCV).
Description:
The inspectors identified that for a postulated fire in fire zone 41, the control room heating, ventilation, and air conditioning (HVAC) system would be damaged. The licensee had analyzed the failure of the control room HVAC system.
However, in the event of a fire, the licensee determined that repairing the control room HVAC system was achievable by re-powering the control room HVAC blower motors using temporary power cables after the fire occurred. The inspectors verified that actions to provide temporary power to the control room HVAC were proceduralized. In addition, the inspectors noted that the licensee had temporary ventilation fans available should such an alternate means of providing ventilation be required. As such, the inspectors determined that steps to provide control room HVAC could reasonably be accomplished from a risk perspective (as opposed to a compliance perspective).
The inspectors concluded that restoration of the control room HVAC system after a fire was essential due to the effect that potential heat stress would have on operators.
Calculations performed by the licensee showed that control room temperatures could eventually reach levels sufficiently high that operators would not be able to perform required actions. Specifically, the calculations showed that the control room could reach 120 degrees (E) Fahrenheit (F) in two hours, 135E F in ten hours, and 175E F in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This condition was originally identified by the licensee in Condition Report (CR)02205039. The licensee resolved the issue by concluding that the restoration of control room HVAC was a cold shutdown activity.
Since manning the control room would be necessary to maintain hot shutdown conditions for a postulated fire in fire zone 41, the inspectors determined that actions to repair the control room HVAC system were hot shutdown repairs. The inspectors determined that the licensees resolution was not appropriate because the restoration was a hot shutdown activity (rather than a cold shutdown activity). As a result, the licensee failed to correct the condition even though it had been identified through the corrective action program.
Analysis:
In accordance with Inspection Manual Chapter (IMC) 0612, the inspectors determined that the issue was more than minor because the finding was associated with the protection against external factors (i.e., fire) attribute of the mitigating systems objective in that one train of systems necessary to achieve and maintain hot shutdown conditions would not be free of fire damage for a postulated fire. In accordance with IMC 0609, Appendix A, the inspectors performed a Significance Determination Process (SDP) Phase 1 screening and determined that the finding degraded the Fire Protection portion of the Mitigating Systems Cornerstone. As such, screening under IMC 0609, Appendix F, was required. Based on review of IMC 0609, Appendix F, the inspectors determined that the finding did require a Phase 2 analysis because a fire protection features was inadequate. However, because steps to provide control room HVAC could reasonably be accomplished, the inspectors determined that the finding was of very low safety significance (Green).
Enforcement:
Title 10 CFR 50.48(b)(2) requires, in part, that all nuclear power plants licensed to operate before January 1, 1979, must satisfy the applicable requirements of Appendix R to this part, including specifically the requirements of Sections III.G, III.J, and III.O. Title 10 CFR Part 50, Appendix R, Section III.G.1 requires, in part, that fire protection features be provided for structures, systems, and components important to safe shutdown. Title 10 CFR Part 50, Appendix R, Section III.G.1 also requires, in part, that the fire protection features be capable of limiting fire damage so that one train of systems necessary to achieve and maintain hot shutdown conditions from either the control room or emergency control station(s) is free of fire damage. The inspectors noted that 10 CFR Part 50, Appendix R, does not have a provision which allows repairs of a system which is required to achieve or maintain hot shutdown conditions. As such, the licensees failure to ensure one train of systems (i.e., control room HVAC) necessary to achieve and maintain hot shutdown would be free of fire damage for a postulated fire in fire zone 41 is a violation of 10 CFR 50.48 and 10 CFR Part 50, Appendix R, Section III.G.1. This violation is associated with a finding that is characterized by the SDP as having very low risk significance (Green) and is being treated as NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy. This violation was entered into the licensees corrective action program as CR 03100011. (NCV 050-315/03-05-01; 050-316/03-05-01)
.3 Post-Fire Safe Shutdown Circuit Analysis
Title 10 CFR Part 50, Appendix R, Section III.G.1, required that structures, systems, and components important to safe shutdown be provided with fire protection features capable of limiting fire damage to ensure that one train of systems necessary to achieve and maintain hot shutdown conditions remained free of fire damage. Options for providing this level of fire protection were delineated in 10 CFR Part 50, Appendix R, Section III.G.2. Where the protection of systems whose function was required for hot shutdown did not satisfy 10 CFR Part 50, Appendix R, Section III.G.2, an alternative or dedicated shutdown capability and its associated circuits, was required to be provided that was independent of the cables, systems, and components in the area. For such areas, 10 CFR Part 50, Appendix R, Section III.L.3, specifically required the alternative or dedicated shutdown capability to be physically and electrically independent of the specific fire areas and capable of accommodating post-fire conditions where offsite power was available and where offsite power was not available for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
a. Inspection Scope
On a sample basis, the inspectors evaluated the adequacy of separation provided for the power and control cabling of redundant trains of shutdown equipment. This investigation focused on the cabling of selected components in systems important for safe shutdown. The inspectors review also included a sampling of components whose inadvertent operation due to fire may adversely affect post-fire safe shutdown capability.
The purpose of this review was to determine if a single exposure fire, in one of the fire areas selected for this inspection, could prevent the proper operation of both safe shutdown trains.
b. Findings
No findings of significance were identified.
.4 Alternative Safe Shutdown Capability
Title 10 CFR Part 50, Appendix R, Section III.G.1, required that structures, systems, and components important to safe shutdown be provided with fire protection features capable of limiting fire damage to ensure that one train of systems necessary to achieve and maintain hot shutdown conditions remained free of fire damage. Options for providing this level of fire protection were delineated in 10 CFR Part 50, Appendix R, Section III.G.2. Where the protection of systems whose function was required for hot shutdown did not satisfy 10 CFR Part 50, Appendix R, Section III.G.2, an alternative or dedicated shutdown capability independent of the area under consideration was required to be provided. Additionally, alternative or dedicated shutdown capability must be able to achieve and maintain hot standby conditions and achieve cold shutdown conditions within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and maintain cold shutdown conditions thereafter. During the post-fire safe shutdown, the reactor coolant process variables must remain within those predicted for a loss of normal alternating current power, and the fission product boundary integrity must not be affected (i.e., no fuel clad damage, rupture of any primary coolant boundary, or rupture of the containment boundary).
a. Inspection Scope
The inspectors reviewed the licensees systems required to achieve alternative safe shutdown to determine if the licensee had properly identified the components and systems necessary to achieve and maintain safe shutdown conditions. The inspectors also focused on the adequacy of the systems to perform reactor pressure control, reactivity control, reactor coolant makeup, decay heat removal, process monitoring, and support system functions.
b. Findings
Introduction:
The inspectors identified that the licensee failed to ensure that alternative shutdown capability for a fire area could accommodate post-fire conditions where off-site power would not be available. This issue was determined to be of very low safety significance and was dispositioned as a Green NCV.
Description:
The inspectors identified that for a postulated fire in fire zone 41, on-site power (i.e., emergency diesel generators) may not be available due to fire damage. The licensee had identified fire zone 41 as a zone which required alternative shutdown capability, i.e., fire zone 41 was required to meet the requirements of 10 CFR Part 50, Appendix R, Section III.G.3. However, the licensee had analyzed that off-site power would be unaffected by any fire in fire zone 41, and therefore would be available to provide power to credited safe shutdown equipment.
Analysis:
In accordance with IMC 0612, the inspectors determined that the issue was more than minor because the finding was associated with the protection against external factors (i.e., fire) attribute of the mitigating systems reactor safety cornerstone and affected the mitigating systems objective in that alternative shutdown capability was not assured for when off-site power would not be available. In accordance with IMC 0609, Appendix A, the inspectors performed a SDP Phase 1 screening and determined that the finding degraded the Fire Protection portion of the Mitigating Systems Cornerstone.
As such, screening under IMC 0609, Appendix F, was required. Based on review of IMC 0609, Appendix F, the inspectors determined that the finding did not require a Phase 2 analysis because no fire protection feature was affected. Additionally, the inspectors did note that offsite power would not be affected by a fire in fire zone 41. As such, this finding was considered to be of very low safety significance (Green).
Enforcement:
Title 10 CFR 50.48(b)(2) requires, in part, that all nuclear power plants licensed to operate before January 1, 1979, must satisfy the applicable requirements of Appendix R to this part, including specifically the requirements of Sections III.G, III.J, and III.O. Compliance with 10 CFR Part 50, Appendix R, Section III.L is considered necessary in order to satisfy the requirements of 10 CFR Part 50, Appendix R, Section III.G. The performance goals contained within 10 CFR Part 50, Appendix R, Section III.L, provide additional measures that must be taken to ensure safety when an alternative shutdown capability is required. These additional measures provide the defense-in-depth necessary when using a method that is not normally used for safe shutdown. This defense-in-depth was not maintained in Fire Zone 41 since only off-site power was credited for a postulated fire in this area. Title 10 CFR Part 50, Appendix R, Section III.L.3, specified, in part, that alternative shutdown capability shall accommodate post-fire conditions where off-site power is available and where off-site power is not available for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The failure to ensure alternative shutdown capability that accommodated post-fire conditions where off-site power would not be available is a violation of 10 CFR 50.48 and 10 CFR Part 50, Appendix R, Section III.L.3. This violation is associated with a finding that is characterized by the SDP as having very low risk significance (Green) and is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy. This violation was entered into the licensees corrective action program as CR 03086071. (NCV 050-315/03-05-02; 050-316/03-05-02)
.5 Operational Implementation of Alternative Shutdown Capability
Title 10 CFR Part 50, Appendix R, Section III.L.2.d, required that the process monitoring function should be capable of providing direct readings of the process variables necessary to perform and control the functions necessary to achieve reactivity control, reactor coolant makeup, and decay heat removal.
a. Inspection Scope
The inspectors performed a walkdown of a sample of the actions defined in procedure 01-OHP-4025-001-001, Emergency Remote Shutdown, and other procedures which were referenced by procedure 01-OHP-4025-001-001. Procedure 01-OHP-4025-001-001 was the procedure for performing a plant alternative shutdown from outside the control room for a fire in the control room, cable vault, and 4 kiloVolt (kV) switchgear rooms. The inspectors reviewed the ability of operators to perform procedure actions within applicable plant shutdown time requirements. The inspectors also focused on equipment labeling being consistent with the procedure.
The inspectors reviews of the adequacy of communications and emergency lighting associated with these procedures are documented in Sections 1R05.6 and 1R05.7 of this report.
b. Findings
No findings of significance were identified.
.6 Communications
For a fire in an alternative shutdown fire area such as the cable spreading room, control room evacuation is required and a shutdown is performed from outside the control room.
Radio communications are relied upon to coordinate the shutdown of both units and for fire fighting and security operations. 10 CFR Part 50, Appendix R, Section III.H., required that equipment provided for the fire brigade include emergency communications equipment.
a. Inspection Scope
The inspectors reviewed the adequacy of the communication system to support plant personnel in the performance of alternative safe shutdown functions and fire brigade duties.
b. Findings
No findings of significance were identified.
.7 Emergency Lighting
Title 10 CFR Part 50, Appendix R, Section III.J., required that emergency lighting units with at least an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> battery power supply be provided in all areas needed for operation of safe shutdown equipment and in access and egress routes thereto.
a. Inspection Scope
The inspectors performed a walkdown of a sample of the actions defined in procedure 01-OHP-4025-001-001, Emergency Remote Shutdown, and other procedures which were referenced by procedure 01-OHP-4025-001-001. As part of the walkdowns, the inspectors focused on the existence of sufficient emergency lighting for access and egress to areas and for performing necessary equipment operations.
b. Findings
Introduction:
The inspectors identified that the licensee failed to ensure that there was adequate emergency lighting for required safe shutdown actions. The issue was considered to be of very low safety significance and was dispositioned as a Green NCV.
Description:
The inspectors identified that there was inadequate emergency lighting for actions required by the alternative shutdown procedure, procedure 01-OHP-4025-001-001, and referenced procedures. Specifically, there was no emergency lighting in the shift managers office. Portable radios, extra procedures, and keys necessary for performing safe shutdown actions were stored in the shift managers office. There was inadequate lighting for storage lockers containing safety gear necessary for operators performing actions involving high voltage switchgear. There was inadequate lighting in the entry area for the radiologically control area for operators to retrieve emergency dosimetry.
The licensee had previously identified that there was no emergency lighting in the shift supervisorss office for the purpose of obtaining keys. The issue was documented on CR P-99-16289, dated June 22,1999. However, the licensee noted that portable lighting (e.g., head lamps) was available and did not take any further immediate corrective actions. The licensee later concluded, inappropriately, that the shift supervisors office was not part of the Appendix R pathway requiring emergency lighting. The licensee subsequently closed the condition report without adding emergency lighting to the shift managers office.
Analysis:
In accordance with IMC 0612, the inspectors determined that the issue was more than minor because the finding was associated with the protection against external factors (i.e., fire) attribute of the mitigating systems reactor safety cornerstone and affected the mitigating systems objective in that the failure to have required emergency lighting could result in a delay of accomplishing safe shutdown actions. In accordance with IMC 0609, Appendix A, the inspectors performed a SDP Phase 1 screening and determined that the finding degraded the Fire Protection portion of the Mitigation Systems Cornerstone. As such, screening under IMC 0609, Appendix F, was required. Based on review of IMC 0609, Appendix F, the inspectors determined that the finding did not require a Phase 2 evaluation because no fire protection feature was affected. Moreover, the inspectors concluded that necessary safe shutdown actions could be accomplished in areas lacking emergency lighting due to the availability of portable head lamps which could be obtained from the control room. As such, this finding was considered to be of very low safety significance (Green).
Enforcement:
Title 10 CFR 50.48(b)(2) requires, in part, that all nuclear power plants licensed to operate before January 1, 1979, must satisfy the applicable requirements of Appendix R to this part, including specifically the requirements of Sections III.G, III.J, and III.O. Title 10 CFR Part 50, Appendix R, Section III.J requires, in part, that emergency lighting units with at least an 8-hour battery power supply be provided in all areas needed for operation of safe shutdown equipment and in access and egress routes thereto. The failure to provide emergency lighting in the shift managerss office, dosimetry issue area at the auxiliary building entrance, and safety gear lockers outside 4 kV switchgear rooms was a violation of 10 CFR 50.48(b)(2) and 10 CFR Part 50, Appendix R, Section III.J.
The failure to provide adequate emergency lighting is a violation of 10 CFR 50.48(b)(2)and 10 CFR Part 50, Appendix R, Section III.J. This violation is associated with a finding that is characterized by the SDP as having very low risk significance (Green) and is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy. This violation was entered into the licensees corrective action program as CR 03085009.
(NCV 050-315/03-05-03; 050-316/03-05-03).
.8 Cold Shutdown Repairs
Title 10 CFR Part 50, Appendix R, Section III.L.5, required that equipment and systems comprising the means to achieve and maintain cold shutdown conditions should not be damaged by fire; or the fire damage to such equipment and systems should be limited so that the systems can be made operable and cold shutdown achieved within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Materials for such repairs shall be readily available onsite and procedures shall be in effect to implement such repairs.
a. Inspection Scope
The inspectors reviewed the licensees procedures to determine if any repairs were required to achieve cold shutdown. The inspectors determined that the licensee did require repair of some equipment to reach cold shutdown based on the safe shutdown methods used. The inspectors reviewed the procedures for adequacy.
b. Findings
No findings of significance were identified.
.9 Fire Barriers and Fire Zone/Room Penetration Seals
Title 10 CFR Part 50, Appendix R, Section III.M, required that penetration seal designs be qualified by tests that are comparable to tests used to rate fire barriers.
a. Inspection Scope
The inspectors reviewed the test reports for three-hour rated barriers installed in the plant and performed visual inspections of selected barriers to ensure that the barrier installations were consistent with the tested configuration. In addition, the inspectors reviewed the fire loading for selected areas to ensure that existing barriers would not be challenged by a potential fire.
b. Findings
Introduction:
During this inspection, the inspectors identified an unresolved item (URI)with respect to use of epoxy floor covering. Specifically, the inspectors identified that the epoxy floor covering applied over cement flooring, such as applied in the auxiliary building and other plant areas, may be a combustible not accounted for in the licensees fire protection program.
Description:
The licensee issued CR03092067 to track weaknesses in the coatings program with respect to procurement, fire protection evaluation, and installation of epoxy floor coatings. Specifically, Design Specification ES-CIVIL-0408-QCN, Protective Coating Systems: Requirements for Material Selection, Surface Preparation, Application and Inspection, and Installation Procedure 12-CHP-5021-CCD-014, Protective Coating Installation Instructions, identified specific design attributes and installation requirements for epoxy floor coatings. Although the licensee had vendor product literature on coatings, no formal flame spread test reports had been maintained.
The NFPA Fire Protection Handbook defines interior finish as materials thicker than 0.9mm (0.03537 inches or 35.37 mils). Procedure 12-CHP-50210-CCD-014 identified the use of Carboline System using a surfacer, primer, and finish coat, with respective thicknesses of 0-20 mils, 1.5-6 mils, and 1.5-6 mils. The procedure also identified Pruett-Schaffer self-leveling epoxy floor coating system which used a primer, intermediate, and finish coat of 5-10 mils, 20-40 mils, and 10-15 mils, respectively. The overall thickness for the Carboline and Pruett-Schaffer epoxy floor coating systems was 32 mils and 65 mils respectively. The licensee measured selected areas for epoxy floor thickness. Floor coating thickness as measured in the Unit 1 4kV switchgear room, Elevation 609, ranged from 6 to 59 mils. Therefore, the Pruett-Schaffer epoxy floor coating would have to be considered an interior finish. In addition, the Carboline would have to be considered an interior finish if it exceeds the thickness requirements identified by the vendor data.
License condition 2.C(4) specified that the licensee shall implement and maintain, in effect, all provisions of the approved Fire Protection Program as described in the Updated Final Safety Analysis Report (UFSAR). Section 9.8.1 of the UFSAR referenced the Fire Protection Program Manual as one of the specific documents to address different facets of the fire protection program. Design Basis Table 5.1 Section D.1 of the Fire Protection Program Manual documented the licensees commitment as:
Interior finishes should be non-combustible or listed by a nationally recognized testing laboratory such as Factory Mutual or Underwriters Laboratory, Inc. for flame spread, some and fuel contribution of 25 or less in its use configuration (ASTM [American Society for Testing and Materials]
E-84 Test, Surface Burning Characteristics of Building Materials). The licensee documented in response to this requirement: Comply with Exception. Specific exceptions to this commitment were listed; however, the epoxy floor covering was not listed as an exception to this commitment.
One area of relief from the licensed requirement is Generic Letter (GL)86-10. GL 86-10 Supplement 1 defines a "non-combustible material" as follows:
Noncombustible Material -
- (a) Material which, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors when subjected to fire or heat;
- (b) Material having a structural base of noncombustible material, with a surfacing not over 1/8-inch thick that has a flame spread rating of not higher than 50 when measured in accordance with ASTM E-84, "Surface Burning Characteristics of Building Materials."
The licensee obtained an Underwriters Laboratory approved test for Carboline 890 epoxy flooring. The results of this test were documented in a Southwest Research Institute Report SwRI Project No. 01-4510-566-a, Investigation of the Surface Burning Characteristics of Two Coats of a Two-Component Cross-Linked Epoxy Coating Applied to 0.25-Inch Thick Glass-Reinforced Cement Board at a Thickness of 4 to 6 Mils Per Coat:
Carboline 890 (System 1); November 2, 1992. The results of the test indicated that Carboline 890 was a Class A material. However, the inspectors determined that this test did not bound the thickness of this type of epoxy flooring. The thickness of the coating used during the tests can result in the same material testing Class A, B, or C material.At the time of this inspection, the licensee had not obtained testing information for the Pruet-Schaffer epoxy floor coating system.
The licensee planned to perform an evaluation, including testing samples of epoxy flooring for flame spread, which would demonstrate acceptability to use epoxy floor covering. This issue will be tracked as an Unresolved Item (URI) pending NRC review of the licensees evaluation. (URI 050-315/03-05-04; 050-316/03-05-04)
.10 Fire Protection Systems, Features, and Equipment
a. Inspection Scope
The inspectors reviewed the material condition, operations lineup, operational effectiveness, and design of fire detection systems, fire suppression systems, manual fire fighting equipment, fire brigade capability, and passive fire protection features. The inspectors reviewed deviations, detector placement drawings, fire hose station drawings, carbon dioxide (CO2) system pre-operational test reports, and fire hazard analysis reports to ensure that selected fire detection systems, sprinkler systems, portable fire extinguishers, and hose stations were installed in accordance with their design, and that their design was adequate given the current equipment layout and plant configuration.
b. Findings
Introduction:
The inspectors identified that the licensee failed to ensure that minimum required concentrations would be achieved for a CO2 system. This issue was determined to be of very low safety significance and was dispositioned as a Green NCV.
Description:
In June 2000, the licensee identified that documentation could not be located demonstrating a pre-operational test for the Unit 1 4kV switchgear room demonstrating that an adequate CO2 concentration could be achieved (documented by CR P-00-10559).
In August 2002, the licensee documented (via CR 02239012) the apparent failure of fire zones 40 (Unit 1 4kV switchgear room) and 42 (Unit 1 Emergency Power Systems Area)to meet minimum CO2 system concentration requirements. To address CR 02239012, the licensee performed Technical Evaluation 12.19 as an evaluation of the CO2 system. The evaluation concluded that the CO2 systems were capable of performing their intended function of containing a fire until the fire brigade arrives. However, the inspectors noted that the evaluation failed to address the non-compliance with NFPA 12 - 1968, Standard on Carbon Dioxide Extinguishing Systems, in that the CO2 systems failed to achieve the required concentrations. Additionally, the inspectors noted that the purpose of a total flooding gaseous suppression system is to extinguish the fire rather than merely contain a fire until the fire brigade arrived at the postulated fire location.
The inspectors reviewed the pre-operational test report for the fire zone 40 CO2 system.
Fire zone 40 consisted of two Unit 1 4.16 kV switchgear rooms and was classified by the licensee as meeting the requirements of 10 CFR Part 50, Appendix R, Section III.G.3.
The test report indicated that maximum concentrations of only 49 percent (%) and 48%
were reached at two sample locations with the maximum concentrations being indeterminate for a third sample location due to a test equipment problem.
The inspectors reviewed the pre-operational test report for the fire zone 42 CO2 system.
Fire zone 42 included the Unit 1 4.16 kV/600 V transformers, control rod drive and inverter rooms and was classified by the licensee as meeting the requirements of 10 CFR Part 50, Appendix R, Section III.G.3. The test report indicated that maximum concentrations of only 46% and 40% were reached at the two sample locations. In addition, in 2000, the licensee performed a modification (Design Change Package 1-DCP-4578) to the configuration of the room that replaced two roll-up doors with sets of fire dampers. The inspectors noted that the fire dampers which replaced the roll-up doors introduced a number of leakage paths which were different than those of the previously installed roll-up doors. No discharge or leakage testing had been conducted to verify that achievable CO2 concentrations would not be adversely affected by the modification.
License condition 2.C(4) specified that the licensee shall implement and maintain, in effect, all provisions of the approved Fire Protection Program as described in the UFSAR.
Section 9.8.1 of the UFSAR referenced the Fire Protection Program Manual as one of the specific documents to address different facets of the fire protection program. Additionally, Section 9.8.1 of the UFSAR listed the Unit 1 electrical switchgear rooms (including both the 4.16 kV switchgear room and the 4.16kV/600V transformers, control rod drive and inverter rooms) as being protected by a low pressure CO2 system. Design Basis Table 5.1 Section E.5 of the Fire Protection Program Manual indicated that the licensee complied with NFPA 12 requirements for minimum required CO2 concentrations with no exceptions. Standard NFPA 12 - 1968, Carbon Dioxide Extinguishing Systems, was the code of record for the CO2 systems installed in fire zones 40 and 42. Section 2421 and Table 6 of NFPA 12 - 1968 specified a design concentration of 50% for dry electrical, wiring insulation hazards in general. Fire zones 40 and 42 contained dry electrical and wiring insulation hazards in general.
Analysis:
In accordance with IMC 0612, the inspectors determined that the issue was more than minor because the finding was associated with the protection against external factors (i.e., fire) attribute of the mitigating systems reactor safety cornerstone and affected the mitigating systems objective in that a fire protection feature (i.e., a fixed suppression system) was adversely affected. In accordance with IMC 0609, Appendix A, the inspectors performed a SDP Phase 1 screening and determined that the finding degraded the Fire Protection portion of the Mitigation Systems Cornerstone. As such, screening under IMC 0609, Appendix F, was required. Based on review of IMC 0609, Appendix F, the inspectors determined that the finding did require a Phase 2 evaluation because a fire protection feature was affected.
For fire zone 40, the inspectors noted that the two Unit 1 4.16 kV switchgear rooms were separated by a concrete wall having at least a 3-hour fire rating. As such, the inspectors determined that a fire could only realistically affect one of the two rooms thereby only affecting one division. Each of the 4.16 kV switchgear rooms had an ignition frequency of 2.9 x 10-3 per year. Manual fire fighting capability would be unaffected. For a fire in one of the switchgear rooms, the inspectors determined that the following mitigating equipment would remain available: one train of motor-driven auxiliary feedwater (AFW),one turbine-driven AFW pump, the ability to cross-connect AFW from Unit 2, one train of power conversion system equipment, one train of component cooling water, one train of safety injection, one train residual heat removal, and pressurizer power-operated relief valves. The inspectors determined that the finding was of very low safety significance (Green) for fire zone 40.
For fire zone 42, the inspectors noted that a fire in the transformer room could potentially affect various components important to safety. The ignition frequency for the transformer room is 7.1 x 10-3 per year. Manual fire fighting capability would be unaffected. For a fire in the transformer room, the inspectors determined that the following mitigating equipment would remain available: power conversion system equipment, both trains of motor-driven AFW pumps, one turbine-driven AFW pump, and the ability to cross-connect AFW from Unit 2. Therefore, the inspectors determined that the finding was of very low safety significance (Green) for fire zone 42.
Enforcement:
The failure to ensure that CO2 minimum required concentrations would be met for fire zones 40 and 42 is a violation of a license condition. This violation is associated with a finding that is characterized by the SDP as having very low risk significance (Green) and is being treated as a NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy. This violation was entered into the licensees corrective action program as Condition Report 03093033. (NCV 050-315/03-05-05; 050-316/03-05-05).
.11 Compensatory Measures
a. Inspection Scope
The inspectors conducted a review to verify that adequate compensatory measures were put in place by the licensee for out-of-service, degraded or inoperable fire protection and post-fire safe shutdown equipment, systems, or features. The inspectors also reviewed the adequacy of short term compensatory measures to compensate for a degraded function or feature until appropriate corrective actions were taken.
b. Findings
No findings of significance were identified.
OTHER ACTIVITIES
4OA2 Identification and Resolution of Problems
a. Inspection Scope
The inspectors reviewed the corrective action program procedures and samples of corrective action documents to verify that the licensee was identifying issues related to fire protection at an appropriate threshold and entering them in the corrective action program.
The inspectors reviewed selected samples of condition reports, work orders, design packages, and fire protection system non-conformance documents.
b. Findings
Three findings of significance relating to the identification and resolution of problems were identified and are described in Sections 1R05.2b, 1R05.7b, and 1R05.10b of this report.
4OA4 Cross-Cutting Issues
1. A finding described in Section 1R05.2b of this report has, as a cause, a problem identification and resolution deficiency. Specifically, despite previously identifying that control room HVAC would be damaged for a postulated fire in fire zone 41, the licensee failed to properly address the issue because the licensee mistakenly believed that performing a repair to the control room HVAC in the event of a fire would meet regulatory requirements.
2. A finding described in Section 1R05.7b of this report has, as a cause, a problem identification and resolution deficiency. Specifically, despite previously identifying that emergency lighting was not available in the shift mangers office, the licensee failed to properly address the issue because the licensee mistakenly believed that the shift managers office was not a safe shutdown pathway.
3. A finding described in Section 1R05.10b of this report has, as a cause, a problem identification and resolution deficiency. Specifically, despite previously identifying that minimum required concentrations for a CO2 system would not be met for two fire zones, the licensee failed to properly address the issue in that the licensee failed to address the non-compliance with the applicable NFPA code.
4OA6 Meeting(s)
Exit Meeting On April 11, 2003, at the conclusion of the on-site inspection activities, the inspectors presented their findings to Mr. Bakken and other members of licensee management at the D.C. Cook Nuclear Power Plant. The licensee did not identify any material reviewed during the inspection as being proprietary.
