SUMMARY OF FINDINGS
IR 05000 382/2012002; 01/01/2012
-03/31/2012
- Waterford Steam Electric Station, Unit 3, Integrated Resident and Regional Report
- Post Maintenance Testing and Surveillance Testing
. The report covered a 3
-month period of inspection by resident inspectors and an announced baseline inspection by a region-based inspector
. Two Green non-cited violations of significance were identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process." The cross-cutting aspect is determined using Inspection Manual Chapter 0310, "Components Within the Cross-Cutting Areas." Findings for which the significance determination process does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG
-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
A. NRC-Identified Findings and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
A Green self-revealing , non-cited violation of Waterford Steam Electric Station, Unit 3
, Technical Specification 6.8.1.a occurred because the licensee did not establish procedures for performing preventive maintenance tasks on the dry cooling tower component cooling water inlet isolation valves CC-135A and CC
-135B limit switches. Specifically, the licensee had not develop ed preventive maintenance tasks to lubricate or replace critical limit switches that provide a permissive for the operation of the dry cooling tower fans. As a result, on February 4, 2011, the limit switch on valve CC-135A failed to operate as designed and rendered an entire train of fans inoperable. The licensee entered this condition into the ir corrective action program as CR
-WF3-201 1-06 7 9 for resolution. The immediate corrective action included the lubrication of the limit switch and the manual stroking of the valve to obtain free and smooth movement of the degraded equipment
. The planned corrective action s include d the development of a preventive maintenance task to lubricate and replace the limit switches on a scheduled frequency. The failure to establish procedures for performing preventive maintenance tasks on the dry cooling tower component cooling water inlet isolation valves CC-135A and CC-135B limit switches is a performance deficiency. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the mitigating systems cornerstone and affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, since there was no preventive maintenance task for lubrication and replacement of the equipment, the limit switches can become stuck and render an entire train of dry cooling tower fans inoperable.
The inspector s determined the significance of the finding using the NRC Inspection Manual 0609, Attachment 0609.04, "Phase 1
- Initial Screening and Characterization of Findings." The inspectors determined that the finding is of very low safety significance (Green) because it is not a design or qualification deficiency, did not represent a loss of a safety function of a system or a single train for greater than its technical specification completion time, and did not screen as potentially risk-significant due to an external initiating events.
The inspectors also concluded that no cross-cutting aspect is applicable to this finding because the performance deficiency is not reflective of current performance (Section 1R19)
.
- Green.
The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI
, because the licensee did not identify and perform testing on a safety-related component to demonstrate that it would perform satisfactor ily in service in accordance with requirements contained in applicable design documents. Specifically, the licensee did not identify and perform proper testing for the essential chiller hot gas bypass valves RFR-106A, B, and C. As a result, the licensee could not demonstrate that the safety-related valves would perform satisfactor ily in service without performing a test and operability evaluation. The licensee entered this condition into the corrective action program as CR-WF3-2012-0632 and CR-WF3-2012-0659. The immediate corrective action included testing the hot gas bypass valves to demonstrate the proper performance of their safety function
. The failure to identify and perform testing to demonstrate that a safety-related component would perform satisfactor ily in service in accordance with requirements contained in applicable design documents is a performance deficiency
. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the mitigating systems cornerstone and affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the hot gas bypass valve closure is required to ensure the essential chiller can perform its safety function during all design basis accident conditions. The inspector s determined the significance of the finding using the NRC Inspection Manual 0609, Attachment 0609.04, "Phase 1
- Initial Screening and Characterization of Findings." The inspectors determined that the finding is of very low safety significance (Green) because it is not a design or qualification deficiency, did no t represent a loss of a safety function of a system or a single train for greater than its technical specification completion time, and did not screen as potentially risk-significant due to an y external initiating events. This finding has a cross-cutting aspect in the resources component of the human performance area in that the licensee did not ensure that complete, accurate, and up-to-date test procedures were available to demonstrate that equipment performance is adequate to assure nuclear safety H.2(c) (Section 1R22).
B. Licensee-Identified Violations
None

REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R01 Adverse Weather Protection
.1 Readiness for Seasonal Extreme Weather Conditions
a. The inspectors performed a review of the adverse weather procedures for seasonal extreme low temperatures. The inspectors verified that weather
-related equipment deficiencies identified during the previous year were corrected prior to the onset of seasonal extremes
, and evaluated the implementation of the adverse weather preparation procedures and compensatory measures for the affected conditions before the onset of, and during, the adverse weather conditions.
Inspection Scope During the inspection, the inspectors focused on plant
-specific design features and the procedures used by plant personnel to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the updated final safety analys is report and performance requirements for systems selected for inspection and verified that operator actions were appropriate as specified by plant
-specific procedures. Specific documents reviewed during this inspection are listed in the attachment. The inspectors also reviewed corrective action program items to verify that plant personnel were identifying adverse weather issues at an appropriate threshold and entering them into their corrective action program in accordance with station corrective action procedures. The inspectors' reviews focused specifically on the following plant systems:
On February 12, 2012, the inspectors completed a review of the licensee's actions in preparation for cold weather conditions, and walked down the following systems and components:
(1) component cooling water system; (2) dry cooling towers; (3) reactor auxiliary building fire protection system; and (4) main steam isolation valve actuators These activities constitute completion of one readiness for seasonal adverse weather sample as defined in Inspection Procedure 71111.01-05.
b. No findings were identified.
Findings
.2 Readiness for Impending Adverse Weather Conditions
a. Since thunderstorms with potential tornados and high winds were forecast in the vicinity of the facility for March 21, 2012, the inspectors reviewed the plant personnel's overall preparations/protection for the expected weather conditions. On March 21, 2012, the inspectors walked down the wet and dry cooling system s because their safety
-related functions could be affected, or required, as a result of high winds or tornado-generated missiles or the loss of offsite power. The inspectors evaluated the plant staff's preparations against the site's procedures and determined that the staff's actions were adequate. During the inspection, the inspectors focused on plant
-specific design features and the licensee's procedures used to respond to specified adverse weather conditions. The inspectors also toured the plant grounds to look for any loose debris that could become missiles during a tornado. The inspectors evaluated operator staffing and accessibility of controls and indications for those systems required to control the plant. Additionally, the inspectors reviewed the updated final safety analys is report and performance requirements for the systems selected for inspection, and verified that operator actions were appropriate as specified by plant
-specific procedures. The inspectors also reviewed a sample of corrective action program items to verify that the licensee identified adverse weather issues at an appropriate threshold and dispositioned them through the corrective action program in accordance with station corrective action procedures. Specific documents reviewed during this inspection are listed in the attachment.
Inspection Scope
These activities constitute completion of one impending adverse weather condition sample as defined in Inspection Procedure 71111.01
-05. b. No findings were identified.

The inspectors attempted to identify any discrepancies that could affect the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, the updated final safety analys is report , technical specification requirements, administrative technical specifications, outstanding work orders, condition reports, 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 inspected 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 with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment
. These activities constitute completion of four partial system walkdown sample s as defined in Inspection Procedure 71111.04-05. b. No findings were identified.
Findings
.2 Complete Walkdown
a. On January 31, 2012, the inspectors performed a complete system alignment inspection of the auxiliary component cooling train B while auxiliary component cooling train A was inoperable for scheduled maintenance. The inspectors selected this system because it was considered both safety significant and risk significant in the licensee's probabilistic risk assessment. The inspectors inspected the system to review mechanical and electrical equipment line ups
- electrical power availability
- system pressure and temperature indications, as appropriate
- component labeling
- component lubrication
- component and equipment cooling
- hangers and supports
- and operability of support systems. The inspectors also inspected the system to ensure that ancillary equipment Inspection Scope or debris did not interfere with equipment operation. The inspectors reviewed a sample of past and outstanding work orders to determine whether any deficiencies significantly affected the system function. In addition, the inspectors reviewed the corrective action program database to ensure that system equipment
-alignment problems were being identified and appropriately resolved. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one complete system walkdown sample as defined in Inspection Procedure 71111.04-05. b. No findings were identified.

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 corrective action program with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of t wo quarterly maintenance effectiveness sample s as defined in Inspection Procedure 71111.12-05. b. No findings were identified.
Findings
1R13 Maintenance Risk Assessments and Emergent Work Control
a. The inspectors reviewed licensee personnel'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 On January 19, 2012, scheduled maintenance activities on the essential chill e r AB with the air handling unit for the switchgear ventilation being out of service On January 26, 2012, scheduled maintenance activities on the high pressure safety injection pump B with a tornado watch and the essential chiller AB being out of service On February 2, 2012, emergent maintenance activities on the containment cooling fan B with the component cooling water inlet isolation valve being out of service On February 12, 2012, emergent maintenance to repair feeder breaker on essential chiller B while essential chiller AB being unavailable On February 29, 2012, scheduled maintenance activities on the emergency diesel generator A On March 19, 2012, scheduled maintenance activities on the emergency diesel generator B lockout feature The inspectors selected these activities based on potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that licensee personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the assessments were accurate and complete. When licensee personnel performed emergent work, the inspectors verified that the licensee personnel promptly assessed and managed plant risk. 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 the technical specification requirements and inspected 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.
These activities constitute completion of six maintenance risk assessments and emergent work control inspection sample s as defined in Inspection Procedure 71111.13-05. b. No findings were identified.

The inspectors evaluated the technical adequacy of the evaluations to ensure that technical specification 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 technical specifications and updated final safety analys is report to the licensee personnel's evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled.
Additionally, the inspectors also reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of six operability evaluations inspection samples as defined in Inspection Procedure 71111.15-0 5.
b. No findings were identified.

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 The inspectors evaluated the activities against the technical specifications, the updated final safety analysis report, 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 postmaintenance tests to determine whether the licensee was identifying problems and entering them in the corrective action program and that the problems were being corrected commensurate with their importance to safety. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of six postmaintenance testing inspection sample s as defined in Inspection Procedure 71111.19-05.
b. Introduction
. A Green self
-revealing non-cited violation of Waterford Steam Electric Station, Unit 3
, Technical Specification 6.8.1.a occurred because the licensee did not establish procedures for performing preventive maintenance tasks on the dry coolin g tower (DCT) component cooling water inlet isolation valves CC-135A and CC-135B limit switches. Specifically, the licensee had not develop ed preventive maintenance tasks to lubricate or replace critical limit switches that provide a permissive for the operation of the DCT fans. Findings Description
. On February 4, 2011, the train A DCT fans did not automatically start to maintain temperature as designed when component cooling water temperature exceeded 92 degrees Fahrenheit. The failure of the DCT fans to start was identified by an alarm in the main control room. An auxiliary component cooling water train A header low pressure alarm occurred when a temperature control valve opened to maintain component cooling water temperature below 95 degrees Fahrenheit. The ultimate heat sink at Waterford Unit 3 is composed of t he component cooling water and auxiliary component cooling water system s. The inability of the DCT fans to auto start rendered train A of the ultimate heat sink inoperable.
The licensee initiated a condition report to evaluate the cause of the problem. The licensee's investigation revealed that the failure of the DCT fans to auto start was due to a stuck limit switch on the train A DCT component cooling water inlet isolation valve CC-135A. The licensee determined that the arm on the limit switch became stuck while the valve was in the closed position.
When the valve opened, the arm on the limit switch remained in the closed position. The inspectors noted from the review of the apparent cause evaluation that the limit switch must indicate that the valve is open to send the permissive signal required to start the DCT fans.
The inspectors concluded that the limit switch became stuck because there was no preventive maintenance task to lubricate and chec k the functional operation of the component. The inspectors determined that there was no preventive maintenance task prescribed for the component because the limit switches were classified as non
-critical component s in the licensee
's preventive maintenance program. The inspectors noted preventive maintenance basi s procedure EN
-DC-335 recommend ed that licensee personnel develop preventative maintenance tasks for those components classified as High or Low. The procedure also suggest ed that components classified as n on-critical or r un-to-failure generally would not have a preventive maintenance task assigned.
The licensee originally classified the limit switch es as high critical components
, but changed the classification in 2006 during a preventive maintenance optimization project. Therefore, the licensee had not develop ed a preventive maintenance task for the limit switches when the licensee reclassified the component. The licensee entered this condition into their corrective action program as CR
-WF3-2011-0679 for resolution. The immediate corrective action included the lubrication of the limit switch and the manual stroking of the valve to obtain free and smooth movement of the degraded equipment.
The planned corrective actions include the development of a preventive maintenance task to lubricate and replace the limit switches on a scheduled frequency.
Analysis.
The failure to establish procedures for performing preventive maintenance tasks on the DCT component cooling water inlet isolation valves CC-135A and CC-135 B limit switches is a performance deficiency. The inspectors determined that it was reasonable for the licensee to be able to foresee and prevent occurrence of this deficiency. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the mitigating systems cornerstone and affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, since there was no preventive maintenance task for lubrication and replacement of the component, the limit switches can become stuck and render an entire train of DCT fans inoperable.
The inspector s determined the significance using the NRC Inspection Manual 0609, Attachment 0609.04, "Phase 1
- Initial Screening and Characterization of Findings." The inspectors determined that the finding is of very low safety significance (Green) because it is not a design or qualification deficiency, did not represent a loss of a safety function of a system or a single train for greater than its technical specification completion time, and did not screen as potentially risk
-significant due to an external initiating events. The inspectors also concluded that no cross
-cutting aspect is applicable to this finding because the performance deficiency is not reflective of current performance since reclassification of the component occurred in 2006
.
Enforcement.
Waterford Steam Electric Station, Unit 3
, Technical Specification 6.8.1.a requires, in part , that procedures shall be established and implemented covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978. Regulatory Guide 1.33, Appendix A, Section 9b states, in part, that preventive maintenance schedules should be developed to specify lubrication schedules, inspections of equipment, and inspection or replacement of parts that have a specific lifetime. Contrary to the above
, from 2006 to the present, the licensee had not develop ed preventive maintenance tasks to specify lubrication and replacement schedules of critical limit switches that provide a permissive for the operation of the DCT fans. As a result, on February 4, 2011, the limit switch on valve CC-135A failed to operate as designed and rendered an entire train of DCT fans inoperable. The immediate corrective action included the lubrication of the limit switch and the manual stroking of the valve to obtain free and smooth movement of the degraded equipment to restore compliance. The licensee entered this condition into their corrective action program as CR
-WF3-2011-0679 for resolution. Because this violation of Technical Specification 6.8.1.a is of very low safety significance and was entered into the licensee's corrective action program, this violation is being treated as a non
-cited violation, consistent with Section 2.3.2 of the Enforcement Policy: NCV 05000382/201 2 00 2-01, "Failure to Develop Preventive Maintenance Tasks for Critical Limit Switches on Component Cooling Water Inlet Isolation Valves
."

. The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI because the licensee did not identify and perform testing on a safety-related component to demonstrate that it would perform satisfactor ily in service in accordance with requirements contained in applicable design documents. Specifically, the licensee did not identify and perform proper testing for the essential chiller hot gas bypass valves RFR-106A, B, and C
. Findings Description
. On January 18, 2012, the AB essential chiller hot gas bypass valve (HGBV) RFR-106C did not open as designed when the ambient temperature fell below a predetermine d set-point on a temperature switch. The licensee noted that the AB essential chiller secured and automatically started five times on load recycle
. The initial troubleshooting assessment determined that the most likely cause was the malfunction of the HGBV since it did not open to artificially load the chiller at low load conditions by introducing a portion of the hot gas from the compressor directly to the cooler. This helps prevent surging of the chiller at low load conditions. The licensee initiated a condition report and a work request to resolve the problem.
The inspectors reviewed the condition report and associated work orders related to this issue. During the review, the inspectors noted that the licensee used three methods to test the HGBV s depending on plant conditions per Attachment 11.12 of Operating Procedure OP 004, "Chilled Water System
." The licensee developed these three methods from a work order task prior to the methods being translated to the procedure in October 2011. However, the inspectors identified that two of the three methods in the procedure and none of the methods specified i n the work order task test ed the safety
-related circuitry associated with the valve. The HGBV circuitry has a safety
-related solenoid valve to close the valve when chilled water temperature increase s to a predetermined set
-point on a temperature switch. The HGBV safety position is to close so that there is full capacity of the chillers to remove heat from the chilled water system during design basis accident conditions. The inspectors determined that each HGBV must be verified operable or be in its safet y-related closed position so that the associated chiller can perform its safety function. The inspectors reviewed the previous surveillances and work order tasks for the essential chiller HGBVs and determined that the safety
-related circuitry to close the HGBV had not been previously demonstrated.
The inspectors concluded that the licensee had not identified and perform ed proper testing for the essential chillers HGBVs.
The licensee entered this condition into the corrective action program as CR
-WF3-2012-0632 and CR
-WF3-2012-0659. The immediate corrective action included testing the HGBVs RFR-106A and 106B to demonstrate the proper performance of their safety function
. The essential chiller HGBV RFR-106C associated with AB essential chiller remained inoperable until the licensee performed corrective maintenance on the valve. The licensee also conducted an operability determination that documented and evaluated the non
-conformance and degraded condition.
Analysis.
The failure to identify and perform testing to demonstrate that a safety
-related component would perform satisfactor ily in service in accordance with requirements contained in applicable design documents is a performance deficiency. The inspectors determined that it was reasonable for the licensee to be able to foresee and prevent occurrence of this deficiency. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the mitigating systems cornerstone and affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences
. Specifically, HGBV closure is required to ensure the essential chiller can perform its safety function during all design basis accident conditions. The inspector s determined the significance using the NRC Inspection Manual 0609, Attachment 0609.04, "Phase 1
- Initial Screening and Characterization of Findings." The inspectors determined that the finding is of very low safety significance (Green) because it is not a design or qualification deficiency, did not represent a loss of a safety function of a system or a single train for greater than its technical specification completion time, and did not screen as potentially risk
-significant due to an y external initiating events. This finding ha s a cross-cutting aspect in the resources component of the human performance area in that the licensee failed to ensure that complete, accurate, and up
-to-date test procedures were available to demonstrate that equipment performance is adequate to assure nuclear safety
Enforcement.
Title 10 of CFR Part 50, Appendix B, Criterion XI, "Test Control," requires, in part , that a test program shall be established to assure that all testing required to demonstrate that structures, systems, and component s will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Contrary to the above, as of February 2, 2012, the licensee had not identified and perform ed testing to demonstrate that a safety
-related component would perform satisfactor ily in service in accordance with requirements contained in applicable design documents. Specifically, the licensee had not identified and perform ed proper testing for the essential chiller HGBVs RFR-106A, B, and C. As a result, the licensee could not demonstrate that the HGBV would close under design basis accident conditions without performing a test and operability evaluation. The licensee performed an operability determination that documented and evaluated this non
-conformance and degraded condition. The licensee entered this condition into the ir corrective action program as CR
-WF3-2012-0632 and CR
-WF3-2012-0659. The immediate corrective action included testing the HGBVs to demonstrate the proper performance of their safety function. Because this violation of Appendix B, Criterion XI is of very low safety significance and was entered into the licensee's corrective action program, this violation is being treated as a non
-cited violation, consistent with Section 2.3.2 of the Enforcement Policy

4OA2 Problem Identification and Resolution
(71152)
.1 Routine Review of Identification and Resolution of Problems
a. As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's corrective action program at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. The inspectors reviewed attributes that included the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensee's corrective action program because of the inspectors' observations are included in the attached list of documents reviewed. Inspection Scope These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure, they were considered an integral part of the inspections performed during the quarter and documented in Secti on 1 of this report.
b. No findings were identified.
Findings
.2 Daily Corrective Action Program Reviews
a. In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow
-up, the inspectors performed a daily screening of items entered into the licensee's corrective action program. The inspectors accomplished this through review of the station's daily corrective action documents.
Inspection Scope The inspectors performed these daily reviews as part of their daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.
b. No findings were identified.
Findings
.3 Selected Issue Follow
-up Inspection a. On January 18, 2012, during a review of items entered in the licensee's corrective action program , the inspectors recognized a corrective action item documenting actions associated with the failure of essential chiller AB relief valve, RFR-107 C. The inspectors reviewed the appropriateness of the assigned significance, the scope and depth of the causal analysis, and the timeliness of the resolution. The inspectors assessed whether the evaluation identified likely causes for the issues and identified appropriate corrective actions to address the identified causes. The inspectors also conducted a review of the corrective actions to verify that appropriate measures were in place to prevent
re occurrence of the issue. In addition, the inspectors assessed whether the licensee's evaluation considered extent of condition, generic implications, common cause, and previous occurrences. The inspectors reviewed the potential impact on nuclear safety and risk to verify that the licensee had taken corrective actions commensurate with the significance of the issue. The inspectors evaluated these actions against the requirements of the licensee's corrective action program and performance attributes contained in IP 71152, Section 03.06.
Inspection Scope
These activities constitute completion of one in-depth problem identification and resolution sample as defined in Inspection Procedure 71152-05.
b. The inspectors reviewed the failure of essential chiller AB relief valve, RFR
-107 C and determined that the vendor specification for the relief valve recommended replacement after five years. However, the existing licensee preventive maintenance task replaced the valves after eight or 10 years (depending on the chiller). Since the relief valve failed after four years, the longer maintenance periodicity did not contribute to the event. The licensee plans to revise the preventive maintenance task to provide a shorter frequency.
Findings and Observations
.4 In-depth Review of Operator Workarounds
a. On March 16, 2012, during a review of items entered in the licensee's corrective action program, the inspectors reviewed operator workarounds and burdens.
