SUMMARY OF FINDINGS
Inspection
Report 05000255/2012002; 01/01/2012
- 03/31/201 2; Palisades Nuclear Plant; Licensed Operator Requalification Program, Maintenance Effectiveness, Refueling and Other Outage Activities This report covers a 3
-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. Three Green finding s were identified
. The finding s were considered non-cited violation s (NCV) of NRC regulations. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP). Cross-cutting aspects were determined using IMC 0310, "Components Within the Cross Cutting Areas." Findings for which the 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 powe r reactors is described in NUREG
-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
A.
Cornerstone: Initiating Events
NRC-Identified
and Self-Revealed Findings Severity Level IVBecause this issue affected the NRC's ability to perform its regulatory function, it was evaluated using the traditional enforcement process, because the issue dealt with licensed operator qualification. The violation is consistent with a Severity Level IV violation using the enforcement policy. The inspectors determined that the underlying technical issue could be evaluated using the SDP. This issue is associated with the Initiating Events cornerstone. The underlying risk significance was determined to be more than minor because if left uncorrected
, this event could have the potential to put unqualified operators in the control room. Specifically, the Reactivity Management Briefing Sheet in SES 130 inadvertently contained Critical Task No. 1 of the scenario. Had the briefing sheet been provided to the evaluated crew with the critical task provided at the bottom of the sheet, the crew would have known one of the performance elements of the scenario for which the crew was being evaluated. The finding screened as Green because all questions for the Initiating Events Cornerstone in Table 4a of IMC 0609 Attachment 4 could be answered 'no.' The inspectors did not identify any applicable cross-cutting aspects associated with this finding in reviewing IMC 0310. (Section 1R11)
. A finding of very low safety significance and associated NCV of 10 CFR 55.49, "Integrity of Examination and Tests" was identified by the inspectors for failure to ensure there were no activities which compromised exam integrity. Specifically, the licensee failed to properly review Simulator Exam Scenario (SES) 130 and the associated Reactivity Management Briefing Sheet. Had the briefing sheet been provided to the crew being evaluated, without inspector intervention, it would have resulted in an exam compromise. The inspectors identified that a critical task was on the crew briefing sheet prior to its administration, and told the licensee of the condition. The licensee subsequently added a page break to push the critical task from the briefing sheet to the following page. There was no actual exam compromise. The licensee also entered the issue in their Corrective Action Program (CAP) as CR-PLP-2012-1001.
GreenThe finding was determined to be greater than minor in accordance with IMC 0612 Appendix B, "Issue Screening," because it is associated with the Initiating Events cornerstone attribute of Equipment Performan ce and adversely impacted the objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during power operations. Specifically, the cause of the feedwater transient which led to a plant trip on December 14, 2011 was intermittent electrical contact between FUZ/Y1014
-2 and its holder clip.
The finding screened as "Green" in the Initiating Events cornerstone by answering "no" to the Transient Initiator question of contributing to both the likelihood of a reactor trip and the likelihood that mitigating equipment or functions would not be available
. The finding had a cross-cutting aspect in the area of problem identification and resolution related to the cross-cutting component of operating experience, in that the licensee implements and institutionalizes operating experience through changes to station processes, procedures, equipment, and training program. In this finding, the issue of "loose fuses," potential causes of these loose fuses, and the potential plant effects this could cause have been identified in externally generated operated experience as well as Palisades
' own operating experience from a loose fuse on a safety-rela te d component in 2011. Therefore, the inspectors determined this issue was reflective of current performance, and the inspectors determined that lessons learned from these identified "loose fuse" issues were not extensively reviewed for applicability throughout systems in the plant and were not fully institutionalized to prevent these issues from recurring
. (P.2(b)) (Section 1R12)
. A self-revealed finding of very low safety significance and associated NCV of Technical Specification (TS) 5.4.1, Procedures, was identified for the failure to adequately implement the fuse control procedure during the reinstallation of a safety-related fuse after maintenance. Specifically, insufficient contact was established between a fuse holder clip and fuse ferrule for safety-related fuse FUZ/Y1014-2 , resulting in the opening of the 'A' Feedwater Pump Recirculation valve, CV-0711 at full power. This induced a feed transient which required operators to manually trip the reactor. The licensee took compensatory actions to ensure the valve was isolated prior to the return to full power operation. The licensee also entered the issue in their CAP as CR-PLP-2012-02182 to further evaluate the conditions of the procedural guidance implementation, procedural disconnects, application of "loose fuse" operating experience, and the extent of condition for other safety-related fuses.
GreenThe finding was determined to be greater than minor in accordance with IMC 0612 Appendix B, "Issue Screening," because it is associated with the Initiating Events Cornerstone attribute of Configuration Control and adversely impacted the objective to limit the likelihood of those events that upset plant stability and challenge critical safety . A finding of very low safety significance with an associated NCV of TS 5.4.1 was self-revealed on January 7, 2012
, for the failure to adequately implement a procedure when indications of Primary Coolant System (PCS) leakage exceeding 10 gallons per minute (gpm) were observed by the control room operators. The finding occurred while the plant was shut down and in a cold shutdown condition. Specifically, the licensee discovered that reactor head vent valves MV
-PC1060B and MV
-PC1060C had not been shut before filling and pressurizing the PCS, contrary to the requirements of procedure SOP-1C, Primary Coolant System-Heatup. The licensee shut the valves and isolated the leak. The leakage resulted in approximately 3000 gallons of primary coolant being transferred to the reactor cavity tilt pit
. This leakage was subsequently drained prior to startup. The licensee entered the issue as CR
-PLP-2012-00165 in their CAP.
functions during power operations.
Specifically, uncontrolled release of coolant from the PCS could challenge plant stability. The issue screened as Green utilizing Attachment 1 of IMC 0609 Appendix G, "Shutdown Operations Significance Determination Process." Specifically, the finding and plant conditions at the time did not warrant the use of a Phase 2 or 3 analysis, because there was no impact on any safety functions. The inspectors determined the cause of the finding was associated with the cross-cutting area of human performance. Specifically, by assuming the reactor head vent valves were not open, operations shift personnel did not use conservative assumptions in decision making and adopt a requirement to demonstrate that a proposed action was safe in order to proceed
. (H.1(b)) (Section 1R20) B. Violations of very low safety significance or Severity Level IV that were identified by the licensee have been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program.
These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.
Licensee-Identified Violations
REPORT DETAILS
The plant began the inspection period at 100% power. On January 5, 2012, the plant commenced a reactor shutdown to replace degraded control rod drive seals suspected of causing elevated primary coolant system leakage. Leakage values remained within technical specification limits before and throughout the shutdown.
Control rod seal packages were replaced and the reactor returned to 100 percent power on January 10, 2012. On March 28, 2012, the plant commenced a downpower to approximately 54 percent to remove the 'A' Cooling Tower from service for replacement. At the conclusion of this inspection period, the plant was holding at approximately 60 percent power for the cooling tower work.
Summary of Plant Status
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R04 Equipment Alignment a. (71111.04)
The inspectors performed partial system walkdowns of the following risk
-significant systems: Inspection Scope
'B' auxiliary feedwater system alignment after pump and valve surveillance testing; high pressure safety injection during maintenance on opposite train
- and 1-2 emergency diesel generator (EDG) during testing of 1
-1 EDG. The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could impact the function of the system and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, Updated Final Safety Analysis Report (UFSAR), Technical Specification (TS)requirements, outstanding work orders, condition reports (CRs), and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies.
The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the Corrective Action Program (CAP) with the appropriate significance characterization. Documents reviewed are listed in the Attachment to this report
. These activities constituted three partial system walkdown sample s as defined in Inspection Procedure (IP) 71111.04-05.
5 Enclosure b. No findings were identified.
Findings 1R05 Fire Protection a. (71111.05)
The inspectors conducted fire protection walkdowns which were focused on availability, accessibility, and the condition of firefighting equipment in the following plant areas:
Inspection Scope Fire Area 22: turbine lube oil room/elev. 590';
Fire Areas 6 & 8: diesel generator 1
-2 and fuel oil day tank rooms
- Fire Area 16
- component cooling pump rooms / elev. 590', 607', 625'
- and Fire Areas 13F&G; boric acid equipment rooms and spent fuel pool heat exchanger room/elev. 590'
. The inspectors reviewed areas to assess if the licensee had implemented a fire protection program that adequately controlled combustibles and ignition sources within the plant, effectively maintained fire detection and suppression capability, maintained passive fire protection features in good material condition, and implemented adequate compensatory measures for out
-of-service, degraded or inoperable fire protection equipment, systems, or features in accordance with the licensee's fire plan. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's Individual Plant Examination of External Events with later additional insights, their potential to impact equipment which could initiate or mitigate a plant transient, or their impact on the plant's ability to respond to a security event. Using the documents listed in the Attachment, the inspectors verified that fire hoses and extinguishers were in their designated locations and available for immediate use; that fire detectors and sprinklers were unobstructed; that transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition. The inspectors also verified that minor issues identified during the inspection were entered into the licensee's CAP. Documents reviewed are listed in the Attachment to this report.
These activities constituted four quarterly fire protection inspection samples as defined in IP 71111.05-05. b. No findings were identified.
Findings 1R11 Licensed Operator Requalification Program
.1
Resident Inspector Quarterly Review a. (71111.11Q)
On January 25, 2012, the inspectors observed a crew of licensed operators in the plant's simulator during licensed operator requalification examinations to verify that operator performance was adequate, evaluators were identifying and documenting crew Inspection Scope
6 Enclosure performance problems, and training was being conducted in accordance with licensee procedures. The inspectors evaluated the following areas:
licensed operator performance; crew's clarity and formality of communications; ability to take timely actions in the conservative direction; prioritization, interpretation, and verification of annunciator alarms; correct use and implementation of abnormal and emergency procedures; control board manipulations; oversight and direction from supervisors; and ability to identify and implement appropriate TS actions and Emergency Plan actions and notifications.
The crew's performance in these areas was compared to pre
-established operator action expectations and successful critical task completion requirements. Documents reviewed are listed in the Attachment to this report.
This inspection constituted one quarterly licensed operator requalification program sample as defined in IP 71111.11. b. No findings were identified.
Findings
.2 Resident Inspector Quarterly Observation of Heightened Activity or Risk
a. (71111.11Q) On March 28, 2012, the inspectors observed operations staff conducting activities in the control room during a downpower to approximately 53 percent in order to take the 'A' Cooling Tower out of service for a planned re
-build. This was an infrequently performed task or evolution that required heightened awareness, just
-in-time training, and was related to an increase in risk.
Inspection Scope On February 21, 2012, the inspectors observed operations staff conducting activities in the control roo m during a 2400V safety
-related off
-site power source bus transfer to prepare for a quarterly TS required surveillance test of the Safety Injection System initiation circuitry. This was an infrequently performed task or evolution that required heightened awareness and was related to an increase in risk.
The inspectors evaluated the following areas:
licensed operator performance; crew's clarity and formality of communications; ability to take timely actions in the conservative direction; prioritization, interpretation, and verification of annunciator alarms; correct use and implementation of procedures; control board manipulations; oversight and direction from supervisors; and ability to identify and implement appropriate TS actions and Emergency Plan actions and notifications (if applicable).
7 Enclosure The performance in these areas was compared to pre
-established operator action expectations, procedural compliance and task completion requirements.
Documents reviewed are listed in the to this report.
This inspection constituted two quarterly licensed operator heightened activity/risk sample s as defined in IP 71111.11. b. No findings were identified.
Findings
.3 Annual Operating Test Results
a. (71111.11A)
The inspectors reviewed the overall pass/fail results of t he Annual Operating Test, administered by the licensee from January 9 through February 10, 2012
, required by 10 CFR 55.59(a). The results were compared to the thresholds established in Inspection Manual Chapter (IMC) 0609, Appendix I, "Licensed Operator Requalification Significance Determination Process
," to assess the overall adequacy of the licensee's Licensed Operator Requalification Training (LORT) program to meet the requirements of 10 CFR 55.59. Inspection Scope This inspection constitutes one a nn ual licensed operator requalification inspection sample as defined in IP 71111.11 A. b. No findings were identified.
Findings
.4 Biennial Review
a. (71111.11B)
The following inspection activities were conducted during the week of January 30, 2012, to assess: 1) the effectiveness and adequacy of the facility licensee's implementation and maintenance of its systems approach to training (SAT) based LORT program , put into effect to satisfy the requirements of 10 CFR 55.59; 2) conformance with the requirements of 10 CFR 55.46 for use of a plant referenced simulator to conduct operator licensing examinations and for satisfying experience requirements; and 3) conformance with the operator license conditions specified in 10 CFR 55.53. The documents reviewed are listed in the Attachment to this report
. Inspection Scope Problem Identification and Resolution (10 CFR 55.59(c); SAT Element 5 as Defined in 10 CFR 55.4): The inspectors evaluated the licensee's ability to assess the effectiveness of its LORT program and their ability to implement appropriate corrective actions to maintain its LORT Program up to date. The inspectors reviewed documents related to the plant's CAP and associated responses (e.g., plant issue matrix and performance review reports; recent examination and inspection reports; licensee event reports (LERs)). The inspectors reviewed the use of operating experience from plant events and 8 Enclosure industry information. The inspectors reviewed the licensee's quality assurance oversight activities.
Licensee Requalification Examinations (10 CFR 55.59(c); SAT Element 4 as Defined in 10 CFR 55.4)- The inspectors reviewed the methodology used to construct the examination including content, level of difficulty , and general quality of the examination/test materials. The inspectors also assessed the level of examination material duplication from week
-to-week for both, the operating tests conducted during the current year, as well as the written examination s administered in 2011. The inspectors reviewed a sample of the written examinations.
- The inspectors reviewed the licensee's program for development and administration of the LORT annual operating test to assess the licensee's ability to develop and administer examinations that are acceptable for meeting the requirements of 10 CFR 55.59(a). - The inspectors observed the administration of the annual operating test to assess the licensee's effectiveness in conducting the examinations, including the conduct of pre
-examination briefings, evaluations of individual operator and crew performance, and post
-examination analysis. The inspectors evaluated the performance of two crew(s) in parallel with the facility evaluators during performance of four dynamic simulator scenarios, and evaluated various licensed crew members concurrently with facility evaluators during the administration of several J ob Performance Measures. - The inspectors assessed the adequacy and effectiveness of the remedial training conducted since the last requalification examinations and the training planned for the current examination cycle to ensure that they addressed weaknesses in licensed operator or crew performance identified during training and plant operations. The inspectors reviewed remedial training procedures and individual remedial training plans.
Conformance with Simulator Requirements Specified in 10 CFR 55.46The inspectors completed IP 71111.11B, Section 03.04, 03.05, 03.06, 03.07, 03.09, and Section 03.10 respectively. However, IP 71111.11B, Section 03.08, "Conformance with Operator License Conditions" to date has not been completed, but completion is expected before the end of the biennial period.
- The inspectors assessed the adequacy of the licensee's simulation facility (simulator) for use in operator licensing examinations and for satisfying experience requirements. The inspectors reviewed a sample of simulator performance test records (e.g., transient tests, malfunction tests, scenario based tests, post
-event tests, steady state tests, and core performance tests), simulator discrepancies, and the process for ensuring continued assurance of simulator fidelity in accordance with 10 CFR 55.46. The inspectors reviewed and evaluated the discrepancy corrective action process to ensure that simulator fidelity was being maintained. Open simulator discrepancies were reviewed for importance relative to the impact on 10 CFR 55.45 and 55.59 operator actions as well as on nuclear and thermal hydraulic operating characteristics.
9 Enclosure b. The licensee identified that a licensed operator did not meet vision requirements as specified in American National Standards Institute (ANSI) 3.4-1983, Section 5.4.5. See Section
4OA7 of this report for discussion on the finding.
Findings No additional findings were identified.
.5 Conformance with Examination Security Requirements
a. (71111.11B)
The inspectors conducted an assessment of the licensee's processes related to examination physical security and integrity (e.g., predictability and bias) to verify compliance with 10 CFR 55.49, "Integrity of Examinations and Tests." The inspectors reviewed the facility licensee's examination security procedure, and observed the implementation of physical security controls (e.g., access restrictions and simulator I/O controls) and integrity measures (e.g., sampling criteria, bank use, and test item repetition) throughout the inspection period. The inspectors reviewed the operating test to assure no unanticipated disclosure of exam material to the examinees.
Inspection Scope
b. Findings
Introduction
- A finding of very low safety significance and associated non-cited violation (NCV) of 10 CFR 55.49, "Integrity of Examination and Tests" was identified by the inspectors for failure to ensure there were no activities which compromised exam integrity.
Specifically, the licensee failed to properly review Simulator Exam Scenario (SES) 130 and the associated Reactivity Management Briefing Sheet.
Had the briefing sheet been provided to the crew being evaluated, it would have resulted in an exam compromise. The inspectors informed the licensee of the issue and the licensee corrected the condition. There was no actual exam compromise.
DescriptionThe inspectors informed the licensee of this condition. The licensee corrected the condition by inserting a page break at the bottom of the briefing sheet to push the critical task to the next page. Two days later, the scenario was administered to two operating crews without any compromise to exam material.
- Prior to administering SES 130 to a crew, the inspectors identified that the Reactivity Management Briefing Sheet in SES 130 that would be given to the crew prior to the scenario contained information pertinent to the exam. Specifically, at the bottom of the Reactivity Management Briefing Sheet, the licensee included Critical Task No. 1 of the scenario. This critical task was one of the crew's performance objectives. Had the inspectors not identified this deficient condition, the operators could have been exposed to exam material for which they were being evaluated. This would have caused a compromise of the examination material and provide undo advantage to the operators.
The inspectors determined the SES 130 package was not carefully reviewed and the error was not identified prior to approving the scenario for administration. The inspectors randomly reviewed four of the ten scenario packages generated by the licensee for requalification testing on a Monday. The licensee corrected this condition prior to the scenario's administration on a Wednesday. The inspectors expanded their scenario review and did not identify any other potential exam compromise conditions. The 10 Enclosure licensee believed that this error would have been detected prior to handing the Reactivity Management Briefing Sheet to the crew. However the inspectors determined that there was no recognized process for its detection other than a chance review of paperwork by an evaluator prior to exam administration.
AnalysisThe inspectors determined that the underlying issue could be evaluated using the significant determination process (SDP). The inspectors validated that the use of traditional enforcement was consistent with IMC 0609, Appendix I, Licensed Operator Requalification SDP, block 11, for exam security issues. This issue is associated with the Initiating Events Cornerstone.
The issue was greater than minor because if left uncorrected, it could result in more serious safety concerns in that there would be a potential to have unqualified operators in the control room. The finding screened as very low safety significance because all questions for the Initiating Events Cornerstone in Table 4a of IMC 06 could be answered 'no.'
The inspectors did not identify any applicable cross
-cutting aspects associated with this finding
, because none of the aspects using IMC 0310 characterized the performance deficiency.
- The failure to properly screen exam material was a performance deficiency warranting further evaluation with IM C 0612 , "Power Reactor Inspection Reports," Appendix B, "Issue Screening." In Block 7, the inspectors determined that a failure to ensure licensed operator exam integrity was an example of an issue that could impact the regulatory process. Specifically, an exam prepared to be given to operators to validate their licensed status had information which could have compromised a portion of the exam. Therefore, the issue was subject to traditional enforcement process. Consistent with the guidance in Section 6.4.d.1.(b) of the Enforcement Policy, the issue was determined to be a Severity Level IV NCV. In accordance with NRC policy, the underlying impact on nuclear safety needed to be evaluated, if possible using the ROP.
EnforcementBecause the finding discussed above was evaluated separately using the SDP, it i s required to be tracked separately and will be given a separate tracking number (NCV 05000255/2012002
-02; Potential Exam Compromise During Requalification Exams). : 10 CFR 55.49, "Integrity of Exams and Tests," states the licensee shall not engage in any activity that compromises the integrity of the exam.
In addition, "The integrity of test or examination is considered compromised if any activity, regardless of intent, affected, or, but for detection, would have affected the equitable and consistent administration of the test or examination-" Contrary to the above, on January 30, 2012, SES 130, an activity previously approved for administration during week four of the requalification exam week, contained exam information on the Reactivity Management Briefing Sheet that if not for detection by the inspectors, would have been given to the examinees, and would have resulted in an exam compromise. In accordance with the NRC Enforcement Policy, this issue was determined to be a Severity Level IV violation since the licensee corrected the condition by inserting a page break at the bottom of the briefing sheet to push the critical task to the next page before the exam was administered to any licensed operator. Because the issue was of very low safety significance, was not willful and it was entered it into the CAP as CR
-PLP-2012-1001, this violation is being treated as an NCV, consistent with the NRC Enforcement Policy (NCV 05000255/2012002
-01, Potential Exam Compromise During Requalification Exams).
11 Enclosure 1R12 Maintenance Effectiveness a. (71111.12)
The inspectors evaluated degraded performance issues involving the following systems: Inspection Scope main feedwater system; and service water system
. The inspectors reviewed events such as where ineffective equipment maintenance had resulted in valid or invalid automatic actuations of engineered safeguards systems and independently verified the licensee's actions to address system performance or condition problems in terms of the following:
implementing appropriate work practices; identifying and addressing common cause failures; scoping of systems in accordance wit h 10 CFR 50.65(b) of the maintenance rule; characterizing system reliability issues for performance; charging unavailability for performance; trending key parameters for condition monitoring; ensuring 10 CFR 50.65(a)(1) or (a)(2) classification or re
-classification; and verifying appropriate performance criteria for structures, systems, and components (SSCs)/functions classified as (a)(2)
, or appropriate and adequate goals and corrective actions for systems classified as (a)(1).
The inspectors assessed performance issues with respect to the reliability, availability, and condition monitoring of the system. In addition, the inspectors verified maintenance effectiveness issues were entered into the CAP with the appropriate significance characterization. Documents reviewed are listed in the to this report
. This inspection constituted two quarterly maintenance effectiveness samples as defined in IP 71111.12-05.
b. Findings
Introduction
- A self-revealed finding of very low safety significance and associated NCV of TS 5.4.1 was identified for the failure to adequately implement the guidance of the fuse control procedure during the reinstallation of a safety
-related fuse after maintenance. Specifically, the fuse installation was not adequate in that insufficient contact was established between the fuse holder clip and fuse ferrule for fuse FUZ/Y1014-2 , resulting in the sporadic operation of the 'A' Feedwater Pump Recirculation valve, CV
-0711. This induced a feedwater transient and required the operators to manually trip the reactor.
Description:
On December 14, 2011 with the plant running at 100 percent power, both Main Feedwater Pumps tripped on low suction pressure, which led operators to take the procedurally required action of manually tripping the reactor. Alarms and indications in the control room illustrated that a feedwater transient had caused the low suction pressure for these pumps. This was due to CV-0711, the 'A' feedwater pump recirculation valve, spuriously opening. Troubleshooting by the licensee determined that the sporadic operation of CV-0711 and other anomalous indications were associated 12 Enclosure with a control circuit supplied through FUZ/Y1014-2. Further investigation by the license e determined that there must have been insufficient contact between the fuse holder clip and one fuse ferrule, which resulted in intermittent electrical contact between the two, and the resulting indications observed by the operators. A laboratory analysis of the fuse, visual inspections showing indications of arcing on the right side of the upper fuse clip, and inspection s of the fuse holder and associated wiring were conducted and led the licensee's root cause team to conclude that this insufficient contact issue as the most probable cause of the event. FUZ/Y1014-2 is powered through an inverter from safety-related 120
-Volt Preferred Alternating Current (AC) power and also supplies portions of the AFW flow control system, making it a safety
-related fuse. The license e changed the classification of this fuse to "safety
-related" in their equipment database after questions from the inspectors, since it had no prior classification. Also as a result of these questions, fuses associated with this circuit will now be replaced after every time they are removed in the future.
The issue of "loose fuses" had been previously identified in other apparent cause evaluations conducted by the licensee. In May 2011, the 'B' Control Room Chiller failed to start because of a loose fuse due to bent spring clips. Corrective actions included developing a list of fuses that are commonly used to tag
-out equipment that may be vulnerable to becoming loose and to perform inspections on those fuses. FUZ/Y1014
-2 was identified on this list of susceptible fuses but was never inspected because the evaluation concluded the existing preventative maintenance program was sufficient.
A loose fuse also caused a trip of the 'A' Control Room Chiller in May 2010. This fuse was regularly removed for tagging purposes. The apparent cause evaluation for this incident stated that "individuals probably have had an opportunity to identify the loose clips before the failure occurred" but a lack of guidance, or lack of recognition of guidance, to verify fuse clip tension could have contributed to the event. Corrective actions from that evaluation included reviewing the requirements of EN
-DC-186 (the fuse control procedure) with the Maintenance and Operations departments and investigating the addition of notes into the eSOMS (electronic logbook and equipment database) system as a reminder for operators to check fuse tightness.
A search into the operating history of FUZ/Y1014-2 showed that it was removed and reinstalled on more than one occasion in order to isolate the circuit for maintenance; most recently in October 2010. Although the present root cause analysis determined there may be disconnects in the guidance for fuse handling between the tagging procedure and the fuse control procedure, the inspectors identified that the tag-out instruction from October 2010 did contain a note that stated adherence to the fuse control procedure was required. Based on this inspector observation, the licensee initiated a CR to assess the root cause analysis and explore whether there were other issues involved with the fuse reinstallation process. Additionally, the licensee identified that NUREG-1760, "Aging Assessment of Safety
-Related Fuses Used in Low-and-Medium-Voltage Applications in Nuclear Power Plants," discussed that fuses and fuse clips are mechanically challenged during removal and reinstallation activities and that these activities can cause intermittent failures of the fuses. The NUREG suggests that fuses that must be removed and inserted frequently for maintenance should be included in periodic maintenance and inspection programs. These practices , the inspectors concluded, were not implemented at the plant and fuses were considered "exempt" from the preventive maintenance program.
13 Enclosure AnalysisThe finding had a cross
-cutting aspect in the area of problem identification and resolution related to the cross
-cutting component of operating experience, in that the licensee implements and institutionalizes operating experience through changes to station processes, procedures, equipment, and training program s. In this finding, the issue of "loose fuses," potential causes of these loose fuses, and the potential plant effects this could cause have been identified in externally generated operated experience in NUREG
-1760, "Aging Assessment of Safety
-Related Fuses Used in Low-and-Medium-Voltage Applications in Nuclear Power Plants
." In addition, the 2010 and 2011 internal operating experience with a loose chiller fuse provided a current opportunity to address loose fuse issues. Therefore, the issue is reflective of current performance, and the inspectors determined that lessons learned from these identified "loose fuse" issues were not extensively reviewed for applicability throughout systems in the plant and were not fully institutionalized to prevent th is issue from recurring
. (P.2(b)) : The inspectors determined that the failure to adequately implement the requirements of the fuse control procedure, EN-DC-186, during the reinstallation of a safety-related fuse after maintenance was a performance deficiency that warranted a significance determination. The inspectors determined that the finding was more than minor in accordance with IMC 0612 "Power Reactor Inspection Reports," Appendix B, "Issue Screening," because it is associated with the Initiating Events Cornerstone attribute of Equipment Performance and adversely impacted the objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during power operations. Specifically, based on the available information, the inspectors conclu ded that the cause of the feedwater transient which led to a plant trip on December 14, 2011
, was intermittent electrical contact between FUZ/Y1014-2 and its holder clip. Utilizing IMC 0609, Attachment 4, "Phase 1
- Initial Screening and Characterization of Findings," Table 4a, for the Initiating Events Cornerstone, the finding screened as Green by answering "no" to the Transient Initiator question of contributing to both the likelihood of a reactor trip and the likelihood that mitigating equipment or functions would not be available.
EnforcementContrary to the above requirements, on October 24, 201 0 , the fuse control procedure EN-DC-186 was not adequately implemented to ensure that fuses that were installed and removed frequently were installed properly and adequately tested. Specifically, a feedwater transient occurred due to spurious electrical contact on fuse FUZ/Y1014-2 , which resulted in a plant trip.
The licensee's corrective actions consisted of moving the electrical circuit associated with FUZ/Y1014
-2 to a different fuse block that was inspected prior to restarting the plant, implementing compensatory measures for CV-0711 to prevent it from inadvertently opening at full power, and creating an operational decision making instruction for operators to operate the plant in this abnormal configuration. The licensee wrote condition report CR
-PLP-2012-02182 to review the root cause report and determine if any updates or revisions are needed
- TS 5.4.1 requires that written procedures shall be established, implemented, and maintained covering the activities in Regulatory Guide 1.33, Revision 2, Appendix A, dated February 1978. Regulatory Guide 1.33, Appendix A, Section 9, specifies procedures for performing maintenance that can affect the safety-related equipment. Specifically, it is stated that the maintenance should be properly pre
-planned and completed in accordance with written procedures and documented instructions appropriate to the circumstances.
The fuse control procedure , EN-DC-186, provides the requirements for fuse maintenance and testing
.
14 Enclosure based on the information presented in this finding. The licensee currently has corrective actions in place to develop interim guidance on fuse installation and removal, investigate revising the tagging procedure, identify alternate methods of fuse block tag
-outs, and conduct an extent of condition for other safety
-related fuses
. Because the issue was of very low safety significance, was not willful and it was entered into the CAP as CR-PLP-2012-02182, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy (NCV 05000255/2012002
-03, Intermittent Fuse Contact Causes Feedwater Transient and Plant Trip.
) 1R13 Maintenance Risk Assessments and Emergent Work Control a. (71111.13)
The inspectors reviewed the licensee's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk
-significant and safety
-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work:
Inspection Scope forced outage for control rod drive mechanism (CRDM)leakage; emergent work on turbine control system during power operations
- high risk work week that include d radiography and safety
-related electrical bus relay calibrations
- troubleshooting of Direct Current (DC) bus ground
- and electrical ground on 1
-2 EDG air start solenoid
. These activities were selected based on their potential risk significance relative to the Reactor Safety Cornerstones. As applicable for each activity, the inspectors verified that risk assessments were performed as required by 10 CFR 50.65(a)(4) and were accurate and complete. When emergent work was performed, the inspectors verified that the plant risk was promptly reassessed and managed. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed TS requirements and walked down portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met.
Specific documents reviewed during this inspection are listed in the Attachment to this report.
These maintenance risk assessments and emergent work control activities constituted five sample s as defined in IP 71111.13-05. b. No findings were identified.
Findings 1R15 Operability Determinations and Functional Assessments a. (71111.15)
The inspectors reviewed the following issues:
Inspection Scope Increased vibrations on P-50C; fuel oil leakage from the 1
-2 EDG; station battery separator plate issues
- potential safety water injection and refueling water tank leak; missed American Society of Mechanical E ngineers Code testing of a shutdown cooling relief valve
- and erratic reactor protection system thermal margin low pressure annunciators
. The inspectors selected these potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure that TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TS and UFSAR to the licensee's evaluations to determine whether the components or systems were operable. Where compensatory measure s were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with th e
evaluations. Additionally, the inspectors reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Documents reviewed are listed in the to this report
. This operability inspection constituted six sample s as defined in IP 71111.15-05. b. No findings were identified.
Findings 1R 18 Plant Modifications a. (71111.18)
T he inspectors reviewed the following modification(s):
Inspection Scope primary coolant pump
, P-50B , lowering of low flow alarm setpoint temporary modification The inspectors reviewed the configuration changes and associated 10 CFR 50.59 safety evaluation screening against the design basis, the UFSAR, and the TS, as applicable, to verify that the modification did not affect the operability or availability of the affected system(s). The inspectors, as applicable, observed ongoing and completed work activities to ensure that the modifications were installed as directed and consistent with the design control documents; the modifications operated as expected; post-modification testing adequately demonstrated continued system operability, availability, and reliability; and that operation of the modifications did not impact the operability of any interfacing systems. As applicable, the inspectors verified that relevant procedure, design, and licensing documents were properly updated. Lastly, the inspectors discussed the plant modification with operations, engineering, and training personnel to ensure that the individuals were aware of how the operation with the plant modification in place could 16 Enclosure impact overall plant performance.
Documents reviewed in the course of this inspection are listed in the Attachment to this report.
This inspection constituted one temporary modification sample as defined in IP 71111.18-05. b. No findings were identified.
Findings 1R19 Post-Maintenance Testing a. (71111.19)
The inspectors reviewed the following post
-maintenance activities to verify that procedures and test activities were adequate to ensure system operability and functional capability:
Inspection Scope control rod drive 22 and 23 leak checks following seal replacement
- diesel run following fuel injector replacement on 1
-2 EDG; testing of pressurizer vent MV-PC1044B after valve repair
- battery charger #1 maintenance
- and CV-3025 , shutdown cooling heat exchanger outlet valve, stroke time following positioner replacement.
These activities were selected based upon the structure, system, or component's ability to impact risk. The inspectors evaluated these activities for the following (as applicable): the effect of testing on the plant had been adequately addressed; testing was adequate for the maintenance performed; acceptance criteria were clear and demonstrated operational readiness; test instrumentation was appropriate; tests were performed as written in accordance with properly reviewed and approved procedures; equipment was returned to its operational status following testing (temporary modifications or jumpers required for test performance were properly removed after test completion);
and test documentation was properly evaluated. The inspectors evaluated the activities against TS s, the UFSAR, 10 CFR Part 50 requirements, licensee procedures, and various NRC generic communications to ensure that the test results adequately ensured that the equipment met the licensing basis and design requirements. In addition, the inspectors reviewed corrective action documents associated with post-maintenance tests to determine whether the licensee was identifying problems and entering them in the CAP and that the problems were being corrected commensurate with their importance to safety. Documents reviewed are listed in the to this report. This inspection constituted five post-maintenance testing sample s as defined in IP 71111.19-05. b. No findings were identified
. Findings 17 Enclosure 1R20 Outage Activities a. (71111.20)
The inspectors evaluated outage activities for a forced outage that began on January 5, 2012, and continued through January 10, 2012.
The inspectors reviewed activities to ensure that the licensee considered risk in developing, planning, and implementing the outage schedule.
Inspection Scope The inspectors observed or reviewed the reactor shutdown and cooldown, outage equipment configuration and risk management, electrical lineups, control and monitoring of decay heat removal, control of containment activities, startup and heatup activities, and identification and resolution of problems associated with the outage.
The outage was planned and conducted to replace two CRDM seal packages which were suspected of contributing to elevated PCS leakage. The shutdown was conducted prior to technical specification limits being reached.
This inspection constituted one other outage sample as defined in IP 71111.20-05.
b. Findings
Introduction.
A finding of very low safety significance (Green) with an associated NCV of TS 5.4.1 was self
-revealed on January 7, 2012 when a PCS leak of approximately 10 gpm occurred. Contrary to procedure SOP-1C, Primary Coolant System
-Heatup, two reactor head vent valves had been left open during PCS fill and pressurization at the conclusion of the forced outage. As a result, approximately 3000 gallons of primary coolant were transferred from the PCS to the reactor cavity tilt pit in containment.
The finding occurred while the plant was shut down and in a cold shutdown condition.
Description.
The licensee was in a forced outage and had just completed repairs to two CRDM seal packages suspected of having contributed to elevated PCS leakage prior to the shutdown. The PCS water level had been drained to approximately 640 feet to facilitate the work, and on January 7, 2012 the operations crew began to fill and pressurize the PCS in preparation to exit the forced outage. The PCS was filled and pressurized to approximately 250 psi. During this evolution, indications of potential PCS leakage were noted based on volume control tank and containment sump levels. Further investigation revealed that two reactor head vent valves were open (MV-PC1060B and MV
-PC1060C), which provided an open path from the PCS to the reactor cavity area in containment. Leakage was approximately 10 gpm. The licensee shut the two valves, which terminated the leak. Appr oximately 3000 gallons of primary coolant had been transferred to the reactor cavity area. The coolant was drained from the cavity area prior to the plant startup. The licensee determined that contrary to procedure SOP
-1C, Primary Coolant System
-Heatup, the operators filling and pressurizing the PCS had failed to ensure the reactor head vent valves were shut. They made an inappropriate assumption that the valves were never opened by the previous crew during the drain
-down and had marked the steps 'not applicable,' thinking that based on the PCS level required for the maintenance, that the previous crew would have utilized a different vent path. No attempts were made to validate the position of the valves. With the valves located high in the PCS, the leak did not challenge the shutdown safety functions of inventory control nor decay heat removal.
18 Enclosure
Analysis.
The finding screened as very low safety significance (Green) by utilizing IMC 0609 Appendix G, "Shutdown Operations Significance Determination Process." Specifically, utilizing Checklist 2 of Attachment 1, all safety functions delineated on the checklist were maintained and no findings requiring a Phase 2 or Phase 3 analysis were identified. A regional Senior Reactor Analyst was also consulted in the determination.
The failure to appropriately follow steps in SOP
-1C, Primary Coolant System-Heatup, was a performance deficiency which warranted further evaluation in the significance determination process. In accordance with IMC 0612 Appendix B, "Issue Screening," the issue was determined to be greater than minor because it is associated with the Initiating Events Cornerstone attribute of Configuration Control and adversely impacted the objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during power operations. Specifically, the performance deficiency caused a PCS leak of approximately 10 gpm and resulted in the transfer of approximately 3000 gallons of primary coolant to the reactor cavity in containment.
The inspectors determined the cause of the finding was associated with the cross
-cutting area of human performance. Specifically, by assuming the reactor head vent valves were shut with no further validation, operations shift personnel did not use conservative assumptions in decision making and adopt a requirement to demonstrate that a proposed action was safe in order to proceed rather than a requirement to demonstrate that it was unsafe in order to disapprove the action (H.1(b)).
Enforcement.
1R22 TS 5.4
.1 requires that written procedures be established, implemented, and maintained as recommended in Regulatory Guide 1.33, Revision 2, Appendix A , February 1978. Regulatory Guide 1.33 states that instructions for energizing, filling, venting, draining, startup, shutdown, and changing modes of operation should be prepared, as appropriate, for the reactor coolant system. Procedure SOP
-1C, Primary Coolant System
-Heatup, implements instructions for operating the PCS. Contrary to the above, on January 7, 2012, the operating shift crew failed to implement a procedure step in SOP-1C to ensure MV-PC1060B and MV
-PC1060C were shut while filling and pressurizing the PCS. As a result, approximately 3000 gallons of primary coolant were displaced from the PCS to the reactor cavity area over a period of a few hours. After recognizing a potential PCS leak, the licensee identified the valves and shut them, terminating the leak. The licensee entered the issue as CR
-PLP-2012-00165 in their corrective action program. Because the issue was of very low safety significance, was not willful and it was entered into the CAP as CR
-PLP-2012-00165, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. (NCV 05000255/2012002
-04, Failure to Ensure Reactor Head Vents Closed During PCS Fill.) Surveillance Testing a. (71111.22)

- safety injection tank sampling (routine)
- auxiliary feedwater actuation system logic test (routine); safety injection system surveillance testing (routin e); 'B' low pressure safety injection pump (IST); and fuel moves in spent fuel pool to comply with new TS amendment (routine). The inspectors observed in-plant activities and reviewed procedures and associated records to determine the following
did preconditioning occur
- were the effects of the testing adequately addressed by control room personnel or engineers prior to the commencement of the testing; were acceptance criteria clearly stated, demonstrated operational readiness, and consistent with the system design basis; plant equipment calibration was correct, accurate, and properly documented; as-left setpoints were within required ranges; and the calibration frequency was in accordance with TSs, the U FSAR, procedures, and applicable commitments; measuring and test equipment calibration was current; test equipment was used within the required range and accuracy; applicable prerequisites described in the test procedures were satisfied; test frequencies met TS requirements to demonstrate operability and reliability; tests were performed in accordance with the test procedures and other applicable procedures; jumpers and lifted leads were controlled and restored where used; test data and results were accurate, complete, within limits, and valid; test equipment was removed after testing; where applicable for inservice testing activities, testing was performed in accordance with the applicable version of Section XI, American Society of Mechanical Engineers code, and reference values were consistent with the system design basis; where applicable, test results not meeting acceptance criteria were addressed with an adequate operability evaluation or the system or component was declared inoperable; where applicable for safety
-related instrument control surveillance tests, reference setting data were accurately incorporated in the test procedure; where applicable, actual conditions encountering high resistance electrical contacts were such that the intended safety function could still be accomplished; prior procedure changes had not provided an opportunity to identify problems encountered during the performance of the surveillance or calibration test; equipment was returned to a position or status required to support the performance of its safety functions; and all problems identified during the testing were appropriately documented and dispositioned in the CAP.

05000255/2011-005-00, Service Water Pu mp Shaft Coupling Failure, On August 9, 2011, a coupling in the shaft of the C service water pump failed, resulting in loss of service water system flow and pressure. The licensee stabilized service water using ONP
-6.1, Loss of Service Water. Due to the failure, the licensee entered T.S. 3.7.8 condition A, which required shutdown in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> if the pump could not be restored to operable status. Over the next 3 days, the licensee replaced the couplings on the service water pump with new couplings.
The licensee determined that intergranular stress corrosion cracking caused the failure. Intergranular stress corrosion cracking resulted from improper design due to selection of a material without adequate control of material toughnesss. Palisades experienced a similar failure in September 2009. Because of the repeat nature of this failure and potential safety significance, the NRC performed a special inspection which was documented in report 05000255/2011012. In addition, the NRC determined that the final safety significance was White in report 05000255/2011019. Since the failure, the licensee has replaced the couplings in all of the pumps with couplings made of a more suitable material. This LER was reviewed and no additional findings were identified and no additional violations of NRC requirements occurred. Documents reviewed as part of this inspection are listed in the attachment.

An up stream breaker open ed on overcurrent resulting in a loss of the left DC bus. This loss caused an immediate trip of the plant and actuation of main steam isolation valves, safety injection systems, containment isolation systems and auxiliary feed water systems. In addition, the short resulted in loss of about half of the control room indications.

, the turbine driven auxiliary feedwater pump tripped during quarterly surveillance testing. The licensee performed troubleshooting of the pump and concluded that workers improperly applied grease to the knife edge during a maintenance that occurred in a refueling outage. After removing the grease, the licensee tested the pump and returned it to an operable status.
Since the grease had been applied in October 2010, the pump had been inoperable in excess of its allowed outage time. Subsequent analysis and testing in the fall of 2011 identified additional possible causes for the pump trip. The licensee has corrected these potential causes. The NRC identified a White finding associated with the turbine driven auxiliary feedwater failure that is documented in report 05000255/2011017.

05000255/2011 00, Valve Packing Failure Resulted in Reactor Trip and Auxiliary Feedwater System Actuation On September 16, 2011 , with the plant at 100 percent power, unidentified PCS leakage measurements exceeded TS allowed limits. The licensee commenced a reactor shutdown to comply with TS requirements. During the shutdown, unidentified PCS leakage rose to greater than 10 gpm. As a result, the licensee manually tripped the reactor and declared an Unusual Event. The cause of the leakage was failed packing on CV-1057, one of two pressurizer spray control valves. The valve was isolated to 25 Enclosure terminate the leakage and the Unusual Event was exited. The licensee determined the cause of the failed packing was due to inappropriate packing configuration. Specifically, two packing end
-rings had not been installed during the last refueling outage and the gland follower had been inappropriately trimmed several years ago.
The inspectors reviewed this event and issued a Green finding which is documented in Inspection Report 05000255/2011005. This LER was reviewed and no additional findings were identified and no additional violations of NRC requirements occurred.
Documents reviewed as part of this inspection are listed in the attachment. This LER is closed.

.6 (Discussed) Licensee Event Report
05000255/2011 00: Automatic Reactor Trip and Auxiliary Feedwater System Actuation On January 22, 2011
, with the plant at 100 percent power, the operation of relay 251-2/SPG3, station power transformer 1
-3 neutral to ground, actuated a generator direct trip lockout relay (backup), opening the main generator output breake rs to the transmission system causing a turbine trip.
The turbine trip actuated the reactor protective system to trip the reactor due to a loss of load.
The cause for operation of the neutral to ground relay, and subsequent automatic plant trip, was a ground fault on a medium voltage cable that provides electrical power to bus 1G, via breaker 252
-401, from station power transformer 1
-3. The licensee determined the probable cause of the ground fault on the cable was insulation flaws, with the effects of moisture acting on these flaws over time, causing the insulation to degrade.
The licensee removed the affected cable and had a laboratory analysis performed to identify the cause of the failure. The licensee received the analysis but at the time of the inspection report had not completed a site acceptance of it. The inspectors will continue to follow the issue as the report is finalized. During the refueling outage scheduled for the second quarter of 2012, the licensee plans to install new cabling for bus 1G. No new safety issues were identified by the inspectors.
The LER will remain open pending further licensee evaluation.
4OA5 Other Activities
.1 (Closed) Unresolved Item
05000255/1998013
-02: Corrective Action for Potential Fire-Induced Motor Operated Valv e Damage The following finding that affects 10 CFR 50.48 was identified by the NRC and is a violation of NRC requirements. This finding has been screened and determined to warrant enforcement discretion per the Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues as described in the NRC Enforcement Policy
. The inspectors identified an Unresolved Item (URI) during an NRC fire protection inspection in 1998 associated with a failure to adequately modify circuits for several Motor Operated Valves (MOVs). The inspectors determined that the licensee did not ensure that the MOVs would not be actuated by fire
-induced hot shorts in the control room, bypassing their torque and limit switches as described in Information Notice 92-18, "Potential for Loss of Remote Shutdown Capability During a Control Room Fire."
The inspectors reviewed the Palisades licensing basis for the fire protection program, recent industry guidance and NRC documents related to fire induced circuit failures and 26 Enclosure determined that the finding was a violation of 10 CFR Part 50, Appendix R, Section III.G.3. Subsequent to the 1998 inspection the licensee began transition to 10 CFR 50.48(c) (National Fire Protection Association (NFPA) 805). Therefore
, the licensee completed a risk
-assessment evaluation (EA
-PSA-FIRE-06-03, "Owners Review of Use of the Palisades PSA to Evaluate the Importance of MOV Hot Shorts," Revision 0) for this issue to determine if it would qualify for enforcement discretion. The inspectors reviewed the evaluation and did not agree with some of the evaluation assumptions. Since the finding affected multiple MOVs, the inspectors performed a qualitative assessment for each valve separately in accordance with IMC 0609, Appendix F, "Fire Protection Significance Determination Process," and determined that the finding was not associated with a finding of high safety significance (i.e., less than Red). The inspectors concluded that the finding a spect associated with valves MO
-3008, MO-3010, MO-3012, MO-3014, MO-3189, MO-3190, MO-3198 and MO
-3199 could be screened as having a very low safety significance (Green) per Task 1.3.1 of IMC 0609, Appendix F because the valves only affected the ability to reach and maintain a cold shutdown condition.
The inspectors reviewed the following valves associated with Train 1 of the High Pressure Safety Injection: MO-3007, MO-3009, MO-3011, MO-3013. The inspectors also reviewed the following valves associated with Train 2 of High Pressure Safety Injection: MO-3062, MO-3064, MO-3066, MO-3068. Finally, the inspectors reviewed the HPSI/Charging Crosstie Isolation valve MO
-3072, which was used to support the PCS inventory control function. Although the inspectors concluded that all nine MOVs were susceptible to damage preventing manual operation following spurious actuation due to a fire in several common fire areas, the inspectors determined that the finding aspect associated with these MOVs was not of high safety significance (i.e., less than Red) for the following reasons:
1) redundant cables associated with Train 1 and Train 2 MOVs were routed in different raceways and were powered from different motor control centers; 2) cables for these MOVs were only routed in the control room, cable spreading room, and 1C switchgear room where fire detection was present (automatic fire suppression existed in cable spreading room and 1C switchgear room and the control room was continuously staffed); and 3) the safe shutdown credited equipment for these fire areas was not affected (charging pumps and flow path was the credited safe shutdown path).
MO-2140 "Boric Acid Pump Feed Isolation Valve," and MO
-2160 "Safety Injection and Refueling Water Tank Charging Pump Isolation Valve," provided a flowpath for borated water supply. A borated water supply can also be provided via manually operating the Boric Acid Tank Gravity Feed Isolation valves MO
-2169 and MO
-2170. During a fire event, primary coolant makeup is not an immediate action required to be performed with a specific time constraint. Therefore, manual actions for MO
-2169 and MO
-2170 were considered feasible. The inspector s determined that the finding aspect associated with these MOVs was not of high safety significance (i.e., less than Red).
27 Enclosure The Main Steam Isolation Bypass valves (MSIVs) MO
-0501 and MO
-0510 provided steam flow path for decay heat removal via the hogging air ejector as the atmospheric steam dump valves were also susceptible to spurious actuation due to a fire in several common fire areas. Cables for both MSIVs were routed in same raceways in the control room, cable spreading room, 1C switchgear room and part of the turbine building. For most of the routing, except for a short cable run in the turbine building, the cables were protected by smoke detectors and automatic suppression systems installed in the fire areas which provided a level of defense
-in-depth to guard against a fire that could result in cable damage. Therefore, the inspectors determined that the finding aspect associated with these MSIVs was not of high safety significance (i.e., less than Red).
Title 10 CFR 50.48(b)(2) requires, in part, that all nuclear power plants licensed to operate prior to 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.Section III.G.3 of 10 CFR Part 50, Appendix R requires, in part, that alternative shutdown capability should be provided where the protection of systems whose function is required for hot shutdown does not satisfy the requirement of Paragraph III.G.2. Contrary to the above, from 1998 to the present, the licensee did not provide an alternative of dedicated shutdown capability that was free of fire damage. Specifically, control cables for various valves were routed in the control room and other areas where they could have been damaged during a fire event.
The licensee has taken compensatory actions to ensure safe shutdown of the plant is maintained for fire scenarios.
The licensee is in transition to NFPA 805 and therefore the NRC
-identified violation was evaluated in accordance with the four criteria established by the NRC's Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues (10 CFR 50.48) for a licensee in NFPA 805 transition (Section 9 of the Enforcement Policy). The assessment is below: 1. The violation was identified by the NRC for this 1998 URI, but it is highly likely the licensee would have identified the issue within their current transition schedule to NFPA 805
, as they evaluated the open issues for multiple spurious shorts.
2. The violation will be corrected as a result of their transition to 10 CFR 50.48(c). The licensee took immediate corrective and compensatory actions within a reasonable time. The NRC determined these actions were acceptable.
3. There were no earlier opportunities to discover the issue based on the current understanding of multiple spurious shorts. 4. This violatio n was not willful.
The licensee entered this issue into their CAP as CR-PLP-2004-08321, "Risk Significance Evaluation of Appendix R MOVs," dated October 21, 2005. As a result, the inspectors concluded that the violation met all criteria established and the NRC was exercising enforcement discretion to not cite this violation in accordance with the Interim Enforcement Policy Regarding Enforcement Discretion for Certain Fire Protection Issues. This URI is closed.

4OA6 Management Meetings
.1 Exit Meeting Summary
O n April 3, 2012 , the inspector s presented the inspection results to Mr. Tony Vitale and other members of the licensee staff. The licensee acknowledged the issues presented. The inspectors confirmed that none of the potential report input discussed was considered proprietary.
.2 Interim Exit Meetings
Interim exits were conducted for:
The results of the review associated with URI 05000255/1998013
-02, "Corrective Action for Potential Fire
-Induced MOV Damage" with Mr. C. Arnone, Nuclear Safety Assurance Director on April 3, 2012.
The inspectors confirmed that none of the potential report input discussed was considered proprietary.
Proprietary material received during the inspection was returned to the licensee.
4OA7 Licensee-Identified Violations
The following violation of Severity Level IV was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as an NCV.
The licensee identified that a licensed operator did not meet vision requirements in accordance with ANSI
-3.4-1983, Section 5.4.5. The operator tested 20/50 in the better eye with corrective lenses but was erroneously signed as having met the vision requirements by the site doctor in September 2010. In June 2011 the licensee submitted a license renewal for the operator. The operator's license previously had a restriction for the operator to wear prescriptive lenses.
However, the licensee, believing that the individual met vision requirements, submitted the renewal to the NRC without conditions. The NRC approved the renewal. In January 2012 the licensee identified the deficient condition. The operator's license was placed on hold until the operator's vision was retested. The operator, using the same lenses and same testing machine, tested 20/30 in the better eye. This met the ANSI
-3.4-1983 vision requirements.
10 CFR 55.57 requires certification by the licensee of medical conditions and general health conducted by a physician, as part of the medical exam for renewal of an individual license. The licensee failed to ensure the operator met the vision requirements for a licensed operator. This is consistent with a Severity Level IV violation in the Enforcement policy (Section 6.4.d.1).
The licensee documented this in CR-PLP-2012-00080, coached the doctor on the ANSI requirements and informed the NRC. The inspectors reviewed the licensee's corrective actions and determined this to be a NCV in accordance with Section 2.3.2 of the NRC Enforcement Policy.
Using IMC 0612, 29 Enclosure Appendix B, "Issue Screening," the inspectors determined this issue to be of very low risk-significance since the operator met the ANSI requirements using the same lenses during a January 2012 retest; and there was no indication of the operator causing vision-induced errors in the control room.
