One noncited violation of very !o\N significance was identified during this inspection.

Additionally, one licensee-identified finding of very low safety significance is documented in this report. 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. Identification and Resolution of Problems The team reviewed approximately 500 condition reports, work orders, engineering evaluations, root and apparent cause evaluations, and other supporting documentation to determine if problems were being properly identified, characterized, and entered into the corrective action program for evaluation and resolution.

The team reviewed a sample of system health reports, self-assessments, trending reports and metrics, and various other documents related to the corrective action program. Overall, the team determined that the licensee's program for identifying, prioritizing, and correcting conditions adverse to quality was effective.

With few exceptions, the licensee identified conditions adverse to quality at a low threshold, properly classified and evaluated those conditions, and developed appropriate corrective actions. The licensee appropriately evaluated industry operating experience for relevance to the facility and had entered applicable items in the corrective action program. The licensee used industry operating experience when performing root cause and apparent cause evaluations.

In addition, the licensee performed effective quality assurance audits and self-assessments, as demonstrated by self-identification of poor corrective action program performance and identification of ineffective corrective actions. A. NRC-Identified and Self-Revealing Findings Cornerstone:

Mitigating Systems * Green. The inspectors reviewed a self-revealing green noncited violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Actions," for the licensee's failure to take corrective action to address service-induced failures of Gould J-series relays. In response, the licensee initiated condition report CR-RBS-20 10-06032 to ensure that appropriate levels of preventive maintenance are performed on high-critical components.

In response, the licensee initiated condition report CR-RBS-20 10-06032 to ensure that appropriate levels of preventive maintenance are performed on high-critical components.

-2-Enclosure The performance deficiency was the licensee's failure to take adequate corrective actions to address service-induced failures of the high-critical, duty-cycle Gould J-series relay designated as EHS-MCC16B6D-33X1.

This performance deficiency was determined to be more than minor and was therefore a finding because it impacted the Mitigating Systems Cornerstone attribute of equipment performance and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

This finding had very iow safety significance because the finding was not a design or qualification deficiency confirmed not to result in a loss of operability, did not represent a loss of system safety function, did not represent a loss of safety function for a single train for greater than its technical specification allowed outage time, and did not screen as potentially risk significant due to a seismic, flooding or severe weather initiating event. Because the apparent cause of this finding was the licensee's misclassification of the failed relay within the preventive maintenance optimization program in 2008, and because the licensee's performance in that program was not reflective of current licensee performance, no cross-cutting aspect was assigned to this finding (Section 40A2.5). B. Licensee-Identified Violations One violation of very low safety significance, which was identified by the licensee, has been reviewed by the inspectors.

Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. This violation and corrective action tracking number (condition report number) are listed in Section 40A7. -3 -Enclosure The performance deficiency was the licensee's failure to take adequate corrective actions to address service-induced failures of the high-critical, duty-cycle Gould J-series relay designated as EHS-MCC16B6D-33X1.

OTHER ACTIVITIES (OA) 40A2 Problem Identification and Resolution (71152) The team based the following conclusions on the sample of corrective action documents that were initiated in the assessment period, which ranged from July 10, 2009, to the end of the on-site portion of this inspection on May 12, 2011 . . 1 Assessment of the Corrective Action Program Effectiveness a. Inspection Scope The team reviewed approximately 500 root and apparent cause evaluations, work orders, engineering evaluations, and other supporting documentation, from approximately 15,000 that had been issued between July 10, 2009, to May 12, 2011, to determine if problems were being properly identified, characterized, and entered into the corrective action program for evaluation and resolution.

The team also reviewed a sample of system health reports, operability determinations, self-assessments, trending reports and metrics, and various other documents related to the corrective action program. The team evaluated the licensee's efforts in establishing the scope of problems by reviewing selected logs, work requests, self-assessment reports, audit reports, system health reports, action plans, and results from surveillance tests and preventive maintenance tasks. A team member reviewed work requests and attended the licensee's periodic Condition Review Group and the management review committee meetings to assess the reporting threshold, prioritization efforts, and significance determination process, as well as observing the interfaces with the operability assessment and work control processes when applicable.

The team's review included verifying the licensee considered the full extent of cause and extent of condition for problems, as well as how the licensee assessed generic implications and previous occurrences.

The team assessed the timeliness and effectiveness of corrective actions, completed or planned, and looked for additional examples of similar problems.

The team conducted interviews with plant personnel to identify other processes that may exist where problems may be identified and addressed outside the corrective action program. The team also reviewed corrective action documents that addressed past NRC-identified violations to verify that the corrective action addressed the issues as described in the inspection reports. The inspectors reviewed a sample of corrective actions closed to other corrective action documents to verify that corrective actions were still appropriate and timely. The team considered risk insights from both the NRC's and River Bend Station's risk assessments to focus the sample selection and plant tours on risk significant systems and components.

To assess whether problems had been identified and entered into the corrective action program, the team conducted a walkdown of Station Service Water and Emergency Diesel Generator systems. b. Assessments 1. Assessment

-Effectiveness of Problem Identification The team concluded that, generally, the licensee had correctly identified deficiencies that were conditions adverse to quality and had entered those conditions into their corrective action program in accordance with the licensee's corrective action program guidance and NRC requirements.

The team determined that the licensee had identified problems at a low threshold.

Also, the team found no indication of processes where problems may be identified and addressed outside the corrective action program. However, the team made the following observations about the effectiveness of licensee problem identification:

II For the existence of water inside vaults associated with cables within the scope of 10 CFR 50.65, the licensee had not initiated a condition report.

This issue was entered into the corrective action program as CR-RBS-2011-040S1.

e In the same sample of ten measuring and test equipment nonconformance reports, the inspectors found five reports for which the licensee had not completed an independent review, even though those reports involved circumstances that, according to licensee procedures, warranted an independent review. This issue was entered into the corrective action program as CR-RBS-2011-4055. " Prior to this inspection, the licensee had not identified that instructions in Procedure ADM-0029, "Control of Measuring and Test Equipment (M&TE) and the Tool Room Process," Step 10.2.1, for dispositioning measuring and test equipment nonconformance reports were not consistent with similar instructions in Step 5.7.4 [4] of fleet Procedure EN-MA-105, "Control of Measuring and Test Equipment (M&TE)." This issue was entered into the corrective action program as CR-RBS-2011-4055.

This issue was entered into the corrective action program as CR-RBS-2011-03961.

2. Assessment

-Effectiveness of Prioritization and Evaluation of Issues The licensee generally had performed adequate assessments of conditions adverse to quality during this assessment period. The team noted that the immediate and prompt operability assessments reviewed had been completed in a timely manner, except as noted below. For this assessment, the team made the following related observations: " Although the condition described in CR-RBS-201 0-04526 warranted classification as a Category A condition for which a root cause evaluation would be performed, the licensee classified that condition in Category B and completed an apparent-cause evaluation.

This condition report did not include the licensee's basis for claSSifying that condition in Category B rather than Category A. This issue was entered into the corrective action program as CR-RBS-2011-04132. " For the condition described in CR-RBS-201 0-05224, the leak rate determined by the licensee's apparent cause evaluation (a "pencil-sized stream") vilas not consistent with the leak rate that had been used in the jicensee's reportability evaluation (30 drops/minute).

According to the licensee's procedures, the licensee should have initiated a new condition report to document that new -6 -Enclosure information had made the reportability evaluation questionable.

However, the licensee did not initiate that condition report. This issue was entered into the corrective action program as CR-RBS-2011-03834.

.. For the condition described in CR-RBS-201 0-05088 (a heater in a ventilation system not delivering an adequate amount of power), the licensee's reportability evaluation was incomplete, in that the evaluation had concluded that oscillations in heater power were normal, but had failed to consider the low-power condition of the heater. Subsequent analysis demonstrated that the low-power condition had not been reportable.

This issue was entered into the licensee's corrective action program as CR-RBS-2011-03786.

.. The operability evaluation in CR-RBS-201 0-01717 was incomplete, in that the licensee had addressed a small oil leak in the reactor core isolation cooling pump by determining that the leak rate with the pump not running was low enough that pump operability would not have been affected, but had not evaluated the leak rate with the pump operating.

A subsequent evaluation determined that the leak rate with the pump operating did not affect operability of the pump. This issue was entered into the licensee's corrective action program as CR-RBS-20 11-3854. .. According to licensee procedures, the condition in CR-RBS-2009-03080 (repetitive maintenance items and adverse trends in nuisance alarms from the fire protection computer)

warranted classification as a Category C condition, which would have required action to correct the condition.

However, the licensee classified the condition as Category 0, which required only trending the condition with no action to correct it. This condition report did not include the licensee's basis for classifying that condition in Category 0 rather than Category C. This issue was entered into the corrective action program as CR-RBS-201104131.

• For the condition described in CR-RBS-2008-04711 (inadvertent distribution of radioactive materials foilowing automatic initiation of the standby-gas treatment system), the licensee's evaluation had been incomplete, in that the licensee had failed to consider a previous evaluation that had determined that installing sock filters on certain drain lines would not be acceptable during surveillance testing. As a result, the corrective actions developed in CR-RBS-2008-04711 had included installing sock filters on those drain lines to prevent further contamination, and those sock filters had remained on the drain lines during two recent surveillance tests. The licensee's subsequent evaluation determined that installation of the sock filters had not invalidated the surveillance test results. This issue was entered into the corrective action program as CR-RBS-2011-03818.

3. Assessment

--Effectiveness of Corrective Action Program Overall. the team concluded that the licensee had generally deve!oped appropriate corrective actions to address piOblems.

However, the team identified the following two examples of conditions adverse to quality where the licensee had failed to identify or take appropriate corrective action: -7 -Enclosure information had made the reportability evaluation questionable.

However, the licensee did not initiate that condition report. This issue was entered into the corrective action program as CR-RBS-2011-03834.

A subsequent evaluation determined that the leak rate with the pump operating did not affect operability of the pump. This issue was entered into the licensee's corrective action program as CR-RBS-20 11-3854. .. According to licensee procedures, the condition in CR-RBS-2009-03080 (repetitive maintenance items and adverse trends in nuisance alarms from the fire protection computer)

warranted classification as a Category C condition, which would have required action to correct the condition.

However, the licensee classified the condition as Category 0, which required only trending the condition with no action to correct it. This condition report did not include the licensee's basis for classifying that condition in Category 0 rather than Category C. This issue was entered into the corrective action program as CR-RBS-201104131.

• For the condition described in CR-RBS-2008-04711 (inadvertent distribution of radioactive materials foilowing automatic initiation of the standby-gas treatment system), the licensee's evaluation had been incomplete, in that the licensee had failed to consider a previous evaluation that had determined that installing sock filters on certain drain lines would not be acceptable during surveillance testing. As a result, the corrective actions developed in CR-RBS-2008-04711 had included installing sock filters on those drain lines to prevent further contamination, and those sock filters had remained on the drain lines during two recent surveillance tests. The licensee's subsequent evaluation determined that installation of the sock filters had not invalidated the surveillance test results. This issue was entered into the corrective action program as CR-RBS-2011-03818.

3. Assessment

--Effectiveness of Corrective Action Program Overall. the team concluded that the licensee had generally deve!oped appropriate corrective actions to address piOblems.

However, the team identified the following two examples of conditions adverse to quality where the licensee had failed to identify or take appropriate corrective action: -7 -Enclosure Condition report CR-RBS-2010-02476 identified that corrective actions associated with CR-RBS-201 0-01587 had been delayed because they had incorrectly been closed to a global preventive maintenance task that was later closed. This issue was entered into the licensee's corrective action program as CR-RBS-2011-04097.

to The licensee developed CR-RBS-2010-02362 corrective action #14 to implement a vendor recommendation to install capacitors to reduce "chattering" of certain relays in circuits associated with oil heaters of the control building chillers, and thereby improve the reliability of those relays. However, the licensee inappropriately closed that corrective action to a system health report, and, as a result, did not implement that recommendation.

This issue was entered into the corrective action program as CR-RBS-2011-04208 . . 2 Assessment of the Use of Operating Experience a. Inspection Scope The team examined the licensee's program for reviewing industry operating experience, including reviewing the governing procedure and self assessments.

The team reviewed a sample operating experience notifications that had been issued during the assessment period to assess whether the licensee had appropriately evaluated the notifications for relevance to the facility.

The team then examined whether the licensee had entered those items into their corrective action program and assigned actions to address the issues. The team reviewed a sample of root cause evaluations and corrective action documents to verify if the licensee had appropriately included industry-operating experience.

b. Assessment Overall, the team determined that the iicensee was adequately evaluating industry operating experience for relevance to the facility, based on reviewing a sample size of 17 industry operating experience notifications.

The team concluded that the licensee was evaluating industry operating experience when performing root cause and apparent cause evaluations.

Both internal and external operating experience were being incorporated into lessons learned for training and pre-job briefs . . 3 Assessment of Self-Assessments and Audits a. Inspection Scope The team reviewed a sample size of 83 licensee self-assessments, surveillances, and audits to assess whether the licensee was regularly identifying performance trends and effectively addressing them. The team reviewed audit reports to assess the effectiveness of assessments in specific areas. The team evaluated the use of self-and third party assessments, the role of the quality assurance department, and the role of the performance improvement group related to licensee performance.

The specific assessment documents reviewed are listed in the attachment. -8 -Enclosure Condition report CR-RBS-2010-02476 identified that corrective actions associated with CR-RBS-201 0-01587 had been delayed because they had incorrectly been closed to a global preventive maintenance task that was later closed.

Assessment The team concluded that the licensee had an adequate self-assessment process . . 4 Assessment of Work Environment a. Inspection Scope The inspection team conducted informal individual interviews with 23 individuals.

The interviewees represented various functional organizations and ranged across contractor, staff, and supervisor levels. The team conducted these interviews to assess whether conditions existed that would challenge the establishment of a safety conscious work environment at the River Bend Station. b. Assessment Because the team encountered no indication of an issue related to the safety conscious work environment during their interviews with site personnel, the team concluded that the licensee had maintained a safety conscious work environment.

.5 Specific Issues identified During this Inspection Failure to Take Corrective Action for Service-Induced Failures of Gould J-series Relays Introduction.

The inspectors reviewed a self-revealing green noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Actions," for the licensee's failure to take corrective action to address service-induced failures of Gould J-series relays. Description.

On October 9,2008, River Bend Station personnel initiated CR-RBS-2008-05915 to document that valve SWP-MOV4B, standby service water to drywell unit coolers, had failed in the open position.

That valve supplies service water to the drywell unit coolers and has a safety function to close during a loss-of-coolant accident.

A lower-tier apparent-cause evaluation performed by the licensee had determined that the valve had failed due to a coil failure for relay EHS-MCC2B-5A-33X.

The licensee had also determined that the relay had failed because it had been in service beyond its expected lifetime.

The River Bend preventive maintenance template for Gould J10 control relays had established a replacement interval based on not exceeding the expect service life for the given service conditions. (For relays the licensee had classified as high-critical, high-duty-cycle, they had established a 21-year replacement period.) To address extent-of-condition concerns, the licensee had implemented a replacement project for Gould relays deSignated as high-duty-cycle, critical.

Corrective Action 7 to CR-RBS-2008-05915 had established work orders for 127 relays classified as high-duty-cycle, high-critical.

Based on work orders that had been generated, the licensee closed CR-RBS-2008-05915 on November 26, 2008. By July 2009, the licensee had completed work to replace the relays they had classified as high-duty-cyc1e, high-cf!t!caL -9 -Enclosure b.

To address extent-of-condition concerns, the licensee had implemented a replacement project for Gould relays deSignated as high-duty-cycle, critical.

Corrective Action 7 to CR-RBS-2008-05915 had established work orders for 127 relays classified as high-duty-cycle, high-critical.

Based on work orders that had been generated, the licensee closed CR-RBS-2008-05915 on November 26, 2008. By July 2009, the licensee had completed work to replace the relays they had classified as high-duty-cyc1e, high-cf!t!caL -9 -Enclosure On January 16, 2011, valve SWP-MOV55B failed closed. That valve is the Division 2 standby service water return valve to the cooling tower inlet The licensee initiated CR-RBS-2011-00393 to document this issue, During troubleshooting, the licensee found that the valve's control power fuses had failed because the Gould J10 control relay identified as EHS-MCC16B6D-33X1 had shorted out. During an equipment performance evaluation, the licensee discovered that during a preventive maintenance optimization program in 2008, SWP-MOV55B had been misclassified as a non-critical component instead of a high-critical component. (According to licensee Procedure EN-DC 153, "Preventive Maintenance Component Classification," the relay should have been classified as high-critical and high-duty-cycie,)

Consequently.

because the relay had been classified as non-critical, the licensee had not established a recurring preventive maintenance task to periodically replace the relay, The inspectors discovered that the subject relay had been in service for 26 years, well beyond its expected lifetime of 21 years, The inspectors also determined that because this relay had been misclassified, it had not been identified in the scope of the corrective actions identified in CR-RBS-2008-05915.

Consequently, no corrective actions had been implemented to address service beyond its expected life, and the component had been allowed to run to failure. As corrective action to address the misclassification of components within the preventive maintenance optimization system, the licensee initiated condition report CR-RBS-201 0-06032 to ensure that appropriate levels of preventive maintenance are performed on high-critical components.

Analysis, The performance deficiency was the licensee's failure to take adequate corrective actions to address service-induced failures of the high-critical, high-duty-cycle Gould J-series relay designated as EHS-MCC2B-5A-33X.

This performance deficiency was determined to be more than minor and was therefore a finding because it impacted the Mitigating Systems Cornerstone attribute of equipment performance and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, in that this performance deficiency allowed a coil failure that rendered valve SWP-MOV4B inoperable.

The inspectors used Manual Chapter 0609,04, "Phase 1 -Initial Screening and Characterization of Findings," to determine that this finding has very-low safety significance because the finding was not a design or qualification deficiency confirmed not to result in a loss of operability. does not represent a loss of system safety function, does not represent a loss of safety function for a single train for greater than its technical specification allowed outage time, and does not screen as potentially risk significant due to a seismic, flooding or severe weather initiating event The inspectors determined that the apparent cause of this finding was the licensee's misclassification of the failed relay within the preventive maintenance optimization program in 2008. The inspectors considered that the licensee's performance in that program was not reflective of current licensee performance.

so no cross-cutting aspect was assigned to this finding. Enforcement.

Title 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Actions," requires, in part, that measures shall be established to assure that conditions adverse to quality are promptly identified and corrected.

Consequently, on January 16, 2011, the subject relay failed in service and rendered valve SWP-MOV4B inoperable.

Because this finding had very low safety significance, and because the licensee entered this issue into their corrective action program as CR-RBS-2011-04064, this finding is being treated as a noncited violation in accordance with Section 2.3.2 of the Enforcement Policy: NCV 05000458/2011006-01, "Failure to Take Corrective Action for Service-Induced Failures of Gould J-series Relays." 40A6 Meetings Exit Meeting Summary On May 12, 2011, the team presented the inspection results to Mr. Eric Olson (the site Vice President)

and other members of the licensee staff. The licensee acknowledged the issues presented.

The inspectors asked the licensee whether any materials examined during the inspection should be considered proprietary.

No proprietary information was identified.

40A7 Licensee-Identified Violations The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section 2.3.2 of the NRC Enforcement Policy for being dispositioned as a noncited violation.

Failure to Incorporate Key Assumptions into an Abnormal Operating Procedure The licensee identified a non cited violation of Technical Specification 5.4.1, "Procedures," for their failure to incorporate into Procedure AOP-50, "Station Blackout," instructions to open Division I and II equipment room doors within 30 minutes of a station blackout event. The corresponding assumption is used in calculations that determine the licensee's coping during a station blackout.

This violation has Green risk significance because the finding was not a design or qualification deficiency confirmed not to result in a loss of operability, does not represent a loss of system safety function, does not represent a loss of safety function for a single train for greater than its technical specification allowed outage time, and does not screen as potentially risk-significant due to a seismic, flooding or severe weather initiating event.
