SUMMARY

IR 05000334/2015003 and 05000412/2015003; 07/01/2015 - 09/30/2015; Beaver Valley Power

Station, Units 1 and 2; Follow-Up of Events and Notices of Enforcement Discretion.

This report covered a three-month period of inspection by resident inspectors and announced inspections performed by regional inspectors. Inspectors identified one finding of very low safety significance (Green), which did not involve a violation of Nuclear Regulatory Commission (NRC) requirements. The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP), dated April 29, 2015. Cross-cutting aspects are determined using IMC 0310, Aspects Within Cross-Cutting Areas, dated December 4, 2014. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated February 4, 2015. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5.

Cornerstone: Initiating Events

Green.

A self-revealing finding was identified for FENOCs failure to correct a low oil level in the lower motor bearing of the Unit 1 A condensate pump in accordance with NOP-LP-2001, Corrective Action Program. Specifically, FENOC incorrectly cancelled the work order to add oil to the A condensate pump motor and installed a placard on the oil level sight glass with incorrect minimum and maximum oil levels. This led to the motor bearing failure, which caused the pump to trip on overcurrent, and required the operators to insert a manual reactor trip. FENOC entered the issue into their correct action program, condition report (CR) 2015-05256.

The performance deficiency was more-than-minor because it was associated with the human performance attribute of the Initiating Events cornerstone, and adversely affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.

Specifically, NOP-LP-2001, section 4.2.3, states that condition report/correct action owners should ensure that actions are developed to resolve the primary cause identified in the condition report. Instead of correcting the low oil level in the motor, FENOC cancelled the work order to add oil. This subsequently caused the operators to trip the plant when the condensate pump motor bearing overheated and the motor tripped on overcurrent. The inspectors determined that this finding was of very low safety significance (Green) because it did not cause a reactor trip and the loss of mitigation equipment. This finding has a cross-cutting aspect in the area of Human Performance, Consistent Process, because FENOC did not seek input from the appropriate work group (engineering) prior to cancelling the work order to add oil to the condensate pump motor [H.13]. (Section 4OA3)

The inspectors evaluated the technical adequacy of the operability determinations to assess whether 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 UFSAR to FENOCs 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 by FENOC. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations.

b. Findings

No findings were identified.

1R19 Post-Maintenance Testing

a. Inspection Scope

The inspectors reviewed the post-maintenance tests for the maintenance activities listed below to verify that procedures and test activities ensured system operability and functional capability. The inspectors reviewed the test procedure to verify that the procedure adequately tested the safety functions that may have been affected by the maintenance activity, that the acceptance criteria in the procedure was consistent with the information in the applicable licensing basis and/or design basis documents, and that the procedure had been properly reviewed and approved. The inspectors also witnessed the test or reviewed test data to verify that the test results adequately demonstrated restoration of the affected safety functions.

OTHER ACTIVITIES

4OA1 Performance Indicator Verification

.1 Mitigating Systems Performance Index (6 samples)

a. Inspection Scope

The inspectors reviewed FENOCs submittal of the Mitigating Systems Performance Index for the following systems for the period of July 1, 2014, through June 30, 2015:

Unit 1 Heat Removal System (Auxiliary Feedwater)

Unit 2 Heat Removal System (Auxiliary Feedwater)

Unit 1 Residual Heat Removal Systems (Low Head Safety Injection and Recirculation Spray)

Unit 2 Residual Heat Removal System (Recirculation Spray)

Unit 1 Cooling Water System (River Water)

Unit 2 Cooling Water System (Service Water)

To determine the accuracy of the performance indicator data reported during those periods, the inspectors used definitions and guidance contained in NEI Document 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 7. The inspectors also reviewed FENOCs condition reports, mitigating systems performance index derivation reports, event reports, and NRC integrated inspection reports to validate the accuracy of the submittals.

b. Findings

No findings were identified.

.2 Emergency Preparedness Performance Indicators (3 samples)

a. Inspection Scope

The inspectors reviewed data for the following three Emergency Preparedness Performance Indicators for the period April 1, 2014, through March 31, 2015.

Drill and Exercise Performance Emergency Response Organization Readiness ANS Reliability To determine the accuracy of the performance indicator data reported during those periods, the inspectors used definitions and guidance contained in NEI 99-02, Regulatory Assessment Performance Indicator Guidelines, Revision 7.

b. Findings

No findings were identified.

4OA2 Problem Identification and Resolution

.1 Routine Review of Problem Identification and Resolution Activities

a. Inspection Scope

As required by Inspection Procedure 71152, Problem Identification and Resolution, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that FENOC entered issues into the corrective action program at an appropriate threshold, gave adequate attention to timely corrective actions, and identified and addressed adverse trends. 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 corrective action program and periodically attended condition report screening meetings.

b. Findings

No findings were identified.

.2 Semi-Annual Trend Review

a. Inspection Scope

The inspectors performed a semi-annual review of site issues, as required by Inspection Procedure 71152, Problem Identification and Resolution, to identify trends that might indicate the existence of more significant safety issues. In this review, the inspectors included repetitive or closely-related issues that may have been documented by FENOC outside of the corrective action program, such as trend reports, performance indicators, major equipment problem lists, system health reports, maintenance rule assessments, and maintenance or corrective action program backlogs. The inspectors also reviewed FENOCs corrective action program database for the first and second quarters of 2015 to assess condition reports written in various subject areas (equipment problems, human performance issues, etc.), as well as individual issues identified during the NRCs daily condition report review (Section 4OA2.1). The inspectors reviewed the FENOC performance assessment report for February 1, 2015, through July 31, 2015, conducted under NOBP-LP-2023, Performance Assessment and the operations, training, and maintenance departments integrated performance assessment and trending reports to verify that FENOC personnel were appropriately evaluating and trending adverse conditions in accordance with applicable procedures. The inspectors also reviewed a sample of cause evaluations completed within the last year to determine if the corrective actions were appropriate and effective.

b. Findings and Observations

No findings were identified.

The inspectors determined that the performance assessment report followed the guidance in procedure NOBP-LP-2023 in that new and closed elevations and escalations for the reporting period were identified as well as elevations and escalations remaining open. Additionally, performance was rated for each of the ten functional areas including examples of improvement in areas as well as identifying areas where gaps exist. The inspectors determined that, in general, FENOC has been identifying adverse trends in the organization. The inspectors noted that FENOC continues to have challenges in plant status control and control of transient combustibles as evidenced by fleet oversight escalations in these areas that have been open since November 2014 and June 2014 respectively.

For the review of the corrective actions associated with the seven cause evaluations, the inspectors determined that, in general, the corrective actions were appropriate. The inspectors noted that in some instances the corrective actions may not have been effective at reducing the occurrence of the issue. The two examples that follow provide illustration. In CR 2014-16248, pressurizer level control left in manual, the cause was lack of operator adherence to standards for control board manipulations, specifically not properly documenting when a component was taken out of the normal system alignment.

This was similar to the Unit 1 trip in April 2015 caused by lack of proper documentation of required condensate pump motor oil level. In CR 2014-09260, Unit 2 accumulator fill misposition in May 2014, the cause was not following procedures. This is similar to the trip response to the Unit 1 trip in April 2015 when the control room did not follow the emergency operating procedures rules of usage and inappropriately reverted back to a previous step to emergency borate. The inspectors noted procedure use and adherence is a continuing focus area of the operations department as documented in their integrated performance assessment and trending report.

.3 Annual Sample: Plant Equipment Status Control Performance Deficiencies

a. Inspection Scope

The inspectors performed an in-depth review of FENOCs causal analysis, trend reviews, and corrective actions associated with a group of plant equipment status control deficiencies. Specifically, over the period January 2012 to October 2014, station personnel experienced an increased number of unintentional or unexpected component manipulations which either challenged personal or environmental safety or resulted in unplanned technical specification limiting conditions of operation entries. The majority of the errors were associated with maintenance or operational activities during plant refueling outages. In each case, upon discovery immediate corrective action promptly restored appropriate component control. Station personnel entered each issue into the corrective action program individually for evaluation and corrective action.

In January 2013, FENOC Fleet Oversight issued an Elevation Letter to the Beaver Valley Operations Manager, based on a continued trend of events in 2012, which warranted increased management rigor to enforce plant equipment status control standards. In November 2014, Fleet Oversight issued an Escalation Letter to the Beaver Valley Director of Site Operations, because station actions were not sufficient to prevent additional events. Some events resulted in unplanned technical specification limiting condition of operation entries, damage to a safety injection pump, loss of automatic pressurizer level control, and a leak of corrosion inhibitor chemicals. Station personnel performed several self-assessments and initiated condition report CR 2014-16653 to identify and resolve the underlying causes.

The inspectors screened the CR database for the period of January 2013 to June 2015 to identify component mispositioning and plant status control-related performance trends. The inspectors selected 10 CRs, including CR 2014-16653, for detailed review.

The inspectors independently reviewed equipment clearance and plant status control procedures, tagging and mispositioning event station performance indicators, training lesson plans, and selected records. Additionally the inspectors interviewed station personnel to assess current practices and programs for plant equipment status control.

The inspectors discussed plant equipment status control lessons-learned and associated plans for the upcoming 2015 Unit 2 refueling outage with the Operations manager, the Fleet Oversight manager, and the Plant Equipment Status Control station advocate. The inspectors assessed FENOCs problem identification threshold, documentation of the issues, causal analyses, extent-of-condition reviews, compensatory actions, and the prioritization and timeliness of corrective actions to evaluate whether FENOC was appropriately identifying, characterizing, and correcting problems associated with this issue. The inspectors also assessed whether FENOC had identified associated lessons learned and communicated the results to appropriate staff. The inspectors compared the actions taken to the requirements of FENOCs corrective action program and 10 CFR 50, Appendix B.

b. Findings and Observations

No findings were identified.

The inspectors noted that no one was injured due to these errors and no technical specification limiting condition of operation allowed outage times were exceeded.

Notwithstanding, FENOC staff determined that knowledge deficiencies across all disciplines and a station culture that has less than adequate awareness of Plant Equipment Status Control program importance and requirements were the underlying causes of the continued increased number of component mispositioning events.

Corrective actions to improve plant equipment status control included the following:

Performed training needs assessments and developed appropriately focused training plans for individual station work groups The Operations Manager met individually with each Shift Manager to emphasize the importance of field observations, coaching, and Shift Manager ownership of crew performance related to plant equipment status control Effective January 9, 2015, the site established an interim document in hand policy for manipulation of equipment. Specifically, manipulation of any plant component now requires the governing document to be in the field Established a site-wide and individual department advocates to elevate awareness of plant equipment status control during daily activities Completed, or scheduled plant equipment status control training for licensed operators, non-licensed operators, site-wide supervisors, chemists, engineers, radiological health protection technicians, mechanics, electricians, and instrument and control technicians Improved Plant Equipment Status Control committee meeting attendance Incorporated plant equipment status control as a key focus area of the Operations Department Excellence Plan.

The inspectors determined that FENOC staff adequately evaluated the component mispositioning issues, identified reasonable primary and contributing causes, established and implemented adequate corrective actions, and effectively communicated the results to plant staff. However, the inspectors noted no written guidance or charter had been provided to the station or department plant equipment status control advocates. During staff interviews the inspectors observed two weaknesses. First, some workers were not aware that they had a department advocate. Second, the department advocates did not periodically meet or share lessons-learned. This could limit the value, timeliness, and consistency of the advocate in helping maintain department level awareness of the importance of Plant Equipment Status Control. The inspectors discussed this observation with the Operations Manager, who revised the Operations Department Excellence Plan to address the observations.

Corrective actions, implemented since November 2014, had not been in place for sufficient duration for the inspectors to fully assess their effectiveness. Notwithstanding, the inspectors review of station performance indicators, the corrective action database, and the shift operating logs indicated a reduced rate of component mispositioning events from January through June 2015. The inspectors also noted actions implemented to address component clearance and tagging deficiencies helped reduce the number of component mispositioning events in 2015. Furthermore, action to perform an effectiveness review of plant equipment status control corrective actions is scheduled for late 2015, following the Unit 2 refueling outage.

4OA3 Follow-Up of Events and Notices of Enforcement Discretion

(Closed) Licensee Event Report (LER) 05000334/2015-001-00: Manual Reactor Trip and Automatic Auxiliary Feedwater Actuation Due to Condensate Pump Motor Failure On April 15, 2015, FENOC manually tripped Unit 1s reactor at 85 percent power following a condensate pump trip. Prior to the trip, the unit was performing an emergent power reduction after the identification of a degrading condition on the A condensate pump motor. All control rods fully inserted into the core and the auxiliary feedwater system actuated as designed. The unit was stabilized in Mode 3 with main feedwater in service and auxiliary feedwater secured.

Introduction.

A Green self-revealing finding was identified for FENOCs failure to correct a low oil level in the Unit 1 A condensate pump lower motor bearing in accordance with NOP-LP-2001, Corrective Action Program. Specifically, FENOC failed to execute the work order to add oil to the A condensate pump motor and, instead, installed a placard on the oil level sight glass with improper oil level indications. This led to the motor bearing failure, which caused the pump to trip on overcurrent, and required the operators to insert a manual reactor trip.

Description.

In November 2013, the Unit 1 A condensate motor was replaced due to moisture intrusion. During initial oil filling and motor operation, oil leaked around the motor shaft. After contacting the vendor, FENOC determined that the correct oil level was at the bottom of the oil sight glass. During the forced outage in January 2014, the sight glass was replaced with one that has a lower viewing window and a placard was attached with minimum and maximum oil levels. In May 2014, a notification was written to add oil to the motor because oil level in the lower motor bearing had dropped to the minimum level. The notification was incorrectly closed to an existing outage work order for the motor. A second notification was written in June 2014 to add oil to the motor which was converted into a work order and assigned a priority in accordance with NOP-WM-1003. Three additional notifications were written in July 2014 to add oil to the motor. In August 2014, CR 2014-13579 was written to identify that motor lower bearing oil level was below minimum. In September 2014, the superintendent of work planning took ownership to resolve the issue identified in the condition report and incorrectly determined that oil should not be added until the oil level reaches the bottom of the sight glass. This was based on the assumption that the original sight glass was installed. The existing work order and notifications were cancelled, and a corrective action was initiated to install a new placard on the sight glass to show a minimum oil level at the bottom of the sight glass. In February 2015, the old placard was removed and the new placard was installed.

On April 15, 2015, the control room received a high temperature alarm on the condensate pump lower motor bearing. Operators reported oil misting, smoke, and high vibrations at the motor. Operations commenced an unplanned power reduction to 85 percent power. The motor tripped on overcurrent, causing operations to insert a manual reactor trip in accordance with their loss of feedwater procedure.

The inspectors determined that the corrective actions implemented to resolve CR 2014-13579 were not in accordance with NOP-LP-2001. Section 4.2.3 of NOP-LP-2001 states that condition report/correct action owners should ensure that actions are developed to resolve the primary cause identified in the condition report. The corrective action implemented did not resolve the low oil level in the motor.

Analysis.

The inspectors determined that failure to correct the low oil level condition in the A condensate pump motor lower bearing in accordance with NOP-LP-2001, was a performance deficiency that was within the capability of FENOC to foresee and correct, and therefore should have been prevented. The performance deficiency was more-than-minor because it was associated with the human performance attribute of the Initiating Events cornerstone, and adversely affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, cancelling the work order to add oil to the motor bearing subsequently caused the operators to trip the plant when the condensate pump motor bearing overheated due to oil starvation and the motor tripped on overcurrent.

In accordance with IMC 0609, Attachment 4, Initial Characterization of Findings, issued June 19, 2012, and Exhibit 1 of IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012, the inspectors determined that this finding was of very low safety significance (Green) because it did not cause a reactor trip and the loss of mitigation equipment.

This finding has a cross-cutting aspect in the area of Human Performance, Consistent Process, because FENOC did not seek input from the appropriate work group (engineering) prior to cancelling the work order to add oil to the condensate pump motor

[H.13].

Enforcement.

This finding does not involve enforcement action because no violation of a regulatory requirement was identified. FENOC entered this issue into their corrective action program as condition report 2015-05256. Because this finding did not involve a violation and was of very low safety significance (Green), it is identified as a FIN. (FIN 05000334/2015003-01, Failure to Correct a Low Oil Level in the Condensate Pump Motor)
