SUBJECT: VOGTLE ELECTRIC GENERATING PLANT - NRC INTEGRATED INSPECTION REPORT 05000424/2014005 AND 05000425/2014005

Dear Mr. Taber:

On December 30, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Vogtle Electric Generating Plant, Units 1 and 2. On January 27, 2014, the NRC inspectors discussed the results of this inspection with Mr. G. Saxon and other members of your staff. The inspectors documented the results of this inspection in the enclosed inspection report. The inspectors documented three findings of very low safety significance (Green) in this report. All of these findings involved violations of NRC requirements. The NRC is treating these violations as non-cited violations (NCV) consistent with Section 2.3.2 of the Enforcement Policy. If you contest these violations or significance of these NCVs, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Vogtle. If you disagree with a cross-cutting aspect assignment in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region II; and the NRC Resident Inspector at the Vogtle Electric Generating Plant. In accordance with the 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosures, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Document Access and Management System (ADAMS).

SUMMARY OF FINDINGS

IR 05000424/2014-005, 05000425/2014-005; 10/01/2014 - 12/31/2014; Vogtle Electric Generating Plant, Units 1 and 2; Refueling and Other Outage Activities, Surveillance Testing The report covered a three-month period of inspection by resident inspectors and three regional inspectors. There was one NRC-identified and two self-revealing violations identified and documented in this report. The significance of inspection findings are 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 June 19, 2012. The cross-cutting aspects are determined using IMC 0310, "Aspects within the Cross-Cutting Areas" dated December 19, 2013. All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy dated July 9, 2013. The NRC's program for overseeing the safe operations of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," revision 5.

Cornerstone: Mitigating Systems

Green: A self-revealing non-cited violation (NCV) of Technical Specification (TS) 5.4.1.a, "Procedures," was identified for the licensee's failure to implement system operating procedure SOP 13502-2, "Control Rod Drive and Position Indication System," version 42, when resetting the control rod drive system bank overlap unit (BOU). This caused an out-of-sequence control rod insertion that resulted in operators manually tripping the reactor. The licensee correctly reset the BOU prior to restarting the unit and enhanced the procedural guidance for resetting the BOU. The violation was entered into the licensee's corrective action program (CAP) as condition report (CR) 879125.

The performance deficiency (PD) was more than minor because it was associated with the Configuration Control and Equipment Performance attributes of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that improper rod control system equipment lineup affected the licensee's ability to control reactivity. The finding screened as Green because the finding did not affect reactor protection system trip capability or result in an unintentional positive reactivity addition. The inspectors determined the finding had a cross-cutting aspect of "training" in the human performance area because the organization had not provided sufficient practical or hands-on training on resetting the BOU. [H.9] (Section 1R20)

Green: The NRC identified an NCV of TS 5.4.1.a, "Procedures" for the licensee's failure to properly implement administrative control procedure 10019-C, "Control of Safety Related Locked Valves," version 15.3. As a result, two nuclear service cooling water (NSCW) manual valves were not in their required 'locked-open' position. The licensee restored the valves to their 'locked-open' position. The violation was entered into the licensee's corrective action program as condition report 880824. The performance deficiency was more than minor because it was associated with the Equipment Performance and Configuration Control attributes of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that the throttled position of the valves reduced the cooling capability of the associated mitigating systems heat exchangers and the unsecured condition reduced the safety-related locked valve program's objective to control and maintain the configuration of valves required to be in a specified position. The finding screened as Green because the flow rates associated with the valves'

throttled position were determined to be sufficient to maintain the supported systems operability. The inspectors determined the finding had a cross-cutting aspect of "documentation" in the human performance area because the organization provided inaccurate documentation of the valves' manipulation log sheet. [H.7] (Section 1R20)

Green: A self-revealing NCV of TS 5.4.1.a, "Procedures" was identified for the licensee's failure to properly implement maintenance procedures and work order instructions and inadvertently removed the 2AD1CB safety-related battery charger from service while attempting to perform routine battery surveillance on the 2CD1B battery. Upon discovery, the licensee immediately stopped the work and returned the battery charger to service. The licensee entered the condition into their corrective action program as CR 10002493. The performance deficiency was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective in that the opening of the power supply breaker to the incorrect battery charger (2AD1CB) resulted in the charger being inoperable for a total of 30 minutes. The inspectors evaluated the finding using IMC 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012. Because the inspectors answered "No" to all of the Exhibit 2, Mitigating Systems Screening Questions, the inspectors concluded that the finding was (Green).The inspectors determined the finding had a cross-cutting aspect of "Challenge the Unknown" in the Human Performance area because the station operator proceeded in the face of uncertainty. [H.11]

(Section 1R22)

REPORT DETAILS

Summary of Plant Status

Unit 1 began the inspection period at or near full rated thermal power (RTP). On October 2, 2014, operators reduced power to approximately 20 percent RTP due to issues with the turbine main and emergency seal oil pumps. The unit was returned to 100 percent RTP on October 6, 2014, and operated at or near full RTP for the remainder of inspection period. Unit 2 began the inspection period shutdown for a planned refueling outage. The unit was restarted on October 12, 2014, and was manually tripped due to incorrect control rod movement. The unit was restarted on October 13, 2014, and reached 100 percent RTP on October 17, 2014. The unit operated at or near full RTP for the remainder of the inspection period.

1R08 Inservice Inspection Activities

a. InspectionAScope Non-Destructive Examination Activities and Welding Activities: The inspectors conducted an onsite review of the implementation of the licensee's Inservice Inspection (ISI) Program for monitoring degradation of the reactor coolant system (RCS),

emergency feedwater systems, risk-significant piping and components, and containment systems in Unit 2. The inspectors' activities included a review of non-destructive examinations (NDE) to evaluate compliance with the applicable edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC),Section XI (Code of record: 1998 Edition with 2000 Addenda), and to verify that indications and defects were appropriately evaluated and dispositioned, in accordance with the requirements of the ASME Code,Section XI, acceptance standards.

The inspectors observed the following NDE mandated by the ASME Code to evaluate compliance with the ASME Code Section XI and Section V requirements, and if any indications and defects were detected, to evaluate if they were dispositioned in accordance with the ASME Code or an NRC-approved alternative requirement.

Ultrasonic Testing (UT) of pipe-to-elbow weld 21204-043-9-RB, Low Pressure Safety Injection System (LPSI), 6", ASME Class 1

Visual Inspection (VT) of control rod drive mechanism (CRDM) restraints, ASME Class 3 The inspectors observed the welding activities referenced below and reviewed associated documents in order to evaluate compliance with procedures and the ASME Code. The inspectors reviewed the work order (WO), repair and replacement plan, weld data sheets, welding procedures, procedure qualification records, welder performance qualification records, and NDE reports.

WO # SNC551283, Turbine-Driven Auxiliary Feedwater Pump Discharge Line Tie-In, 1/4" support plate weld, AWS D1.1

WO # SNC551283, Turbine-Driven Auxiliary Feedwater Pump Discharge Line Tie-In, 4" weldolet-to-pipe weld, ASME Class 3 During non-destructive surface and volumetric examinations performed since the previous refueling outage, the licensee did not identify any relevant indications that were analytically evaluated and accepted for continued service. Therefore, no NRC review was completed for this inspection procedure attribute.

Pressurized Water Reactor Vessel Upper Head Penetration Inspection Activities: For the Unit 2 vessel head, a bare metal visual and volumetric examinations of the penetration nozzles were not required this outage pursuant to 10 CFR 50.55a, as both examination techniques were performed during the last refueling outage. Therefore, no NRC review was done for this inspection procedure attribute. Boric Acid Corrosion Control Inspection Activities: The inspectors reviewed the licensee's boric acid corrosion control (BACC) program activities to ensure implementation with commitments made in response to NRC GL 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary," and applicable industry guidance documents. Specifically, the inspectors performed an onsite record review of procedures, and the results of the licensee's containment walkdown inspections performed during the current spring refueling outage. The inspectors also interviewed the BACC program owner, conducted an independent walkdown of containment to evaluate compliance with licensee's BACC program requirements, and verified that degraded or non-conforming conditions, such as boric acid leaks, were properly identified and corrected in accordance with the licensee's BACC and corrective action programs. The inspectors reviewed the following CRs and associated corrective actions related to evidence of boric acid leakage, to evaluate if the corrective actions completed were consistent with the requirements of the ASME Code Section XI and 10 CFR Part 50, Appendix B, Criterion XVI.

642858, Moderate Dry White Residue on Pipe Cap Downstream of Valve 21205X4028

658459, Heavy Boron Buildup on Valve 2-1208-U4-287

741269, Minor-to-Moderate Dry White Residue from Pipe Cap Downstream of Valve 21208X4018

785964, Moderate Dry White Residue from Packing of Valve 2FV0110A The inspectors reviewed the following engineering evaluations completed for evidence of boric acid leakage to determine if degraded components were documented in the CAP.

The inspectors also evaluated corrective actions for any degraded components to determine if they met the ASME Section XI Code.

648124, Boric Acid Leak on Seal Injection Filter #4

650720, Filter 2-1208-F4-005 Anchor Bolt Degraded Due To Boric Acid Leak

854077, Heavy Moist Discolored Boric Acid Residue below Valve 21208X4477

Steam Generator Tube Inspection Activities: The inspectors reviewed the eddy current (EC) examination activities performed in Unit 2 steam generators (SGs) 1, 2, 3, and 4 during the end-of-cycle 17 refueling outage, to verify compliance with the licensee's Technical Specifications, ASME BPVC Section XI, and Nuclear Energy Institute (NEI)97-06, "Steam Generator Program Guidelines." The inspectors interviewed licensee personnel and vendor staff responsible for the SG inspection project, and reviewed documentation associated with the SG inspections and integrity assessments, as described in this report section. The inspectors reviewed the scope of the EC examinations to verify that known and potential areas of tube degradation were inspected. The inspectors also verified that inspection scope expansion criteria were implemented based on inspection results, as directed by the Electric Power Research Institute (EPRI) "Pressurized Water Reactor Steam Generator Examination Guidelines, Revision 7."

The inspectors reviewed documentation for a sample of EC data analysts, EC probes, and EC testers to verify that personnel and equipment were qualified to detect the existing and potential degradation mechanisms applicable to Vogtle's SG tubes, in accordance with the EPRI Examination Guidelines. This review included a sample of site-specific Examination Technique Specification Sheets (ETSSs) that were selected based on plant-specific and industry operating experience, to ensure that their qualification and site-specific implementation were consistent with Appendix H or I of the EPRI Examination Guidelines. The selected ETSSs for review consisted of bobbin and rotating pancake coil (RPC) probe techniques that were used to detect wear as well as outside diameter stress corrosion cracking. The inspectors also reviewed a sample of EC data with a qualified data analyst to confirm that data analysis was performed in accordance with the applicable ETSSs, and site-specific analysis guidelines. The inspectors verified that the equipment configuration was consistent with the essential parameters of the applicable technique. The inspectors also verified that recordable indications were detected and sized in accordance with vendor procedures. As part of the EC data review, the inspectors verified that the EC indications on each selected tube were consistent with historical data relative to the number of indications, location, and size. The sample of EC data selected for review is listed below:

Steam Generator Tube Row/Column Eddy Current Probe 1 01/42 Bobbin, RPC 1 43/55 Bobbin, RPC 1 47/84 RPC 32/49 RPC 44/42 Bobbin

The inspectors selected a sample of wear degradation mechanisms from the Steam Generator Degradation Assessment, and verified that the in-situ pressure testing criteria were determined in accordance with the EPRI Tube Integrity Guidelines. Additionally, the inspectors reviewed EC indication reports to determine whether tubes with relevant indications were appropriately screened for in-situ pressure testing.

The inspectors compared the recent EC examination results with the last Operational Assessment report for the SGs to assess the licensee's prediction capability for maximum tube degradation. The inspectors verified that the licensee's evaluation was conservative, and that current examination results were bound by the Operational Assessment projections. The inspectors also compared past examination results discussed in the latest Degradation Assessment with the recent EC examination results to verify that new degradation mechanisms, if any, were identified and evaluated before plant startup.

The review of EC examination results included the disposition of potential loose part indications on the SG secondary side, to verify that corrective actions for evaluating and retrieving loose parts were consistent with the EPRI guidelines. The inspectors also reviewed a sample of primary-to-secondary leakage data for Unit 2 to confirm that operational leakage in all SGs remained below the action level threshold during the previous operating cycle.

Based on the review of the final EC examination results and interviews with the licensee, the inspectors confirmed that no EC scope expansion was required and none of the SG tubes examined met the criteria for plugging or in-situ pressure testing. The inspectors also interviewed licensee staff about any planned secondary side visual inspection activities to verify that potential areas of degradation (e.g. loose part wear) were inspected based on recent EC examination results. The inspectors confirmed that no secondary side inspections and Foreign Object Search and Retrieval (FOSAR) activities were performed based on the latest results of EC examination activities.

Identification and Resolution of Problems: The inspectors reviewed a sample of ISI related problems that were identified by the licensee and entered into the CAP as CRs to confirm the licensee had appropriately described the scope of the problem and had initiated corrective actions. The review also included the licensee's consideration and assessment of operating experience events applicable to the plant. The inspectors performed this review to ensure compliance with 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," requirements. Documents reviewed are listed in the Attachment.

b. Findings

.1 Failure to Correctly Implement Control Rod Drive System Procedure During Reactor Startup Activities

Introduction:

A Green self-revealing NCV of TS 5.4.1.a, "Procedures," was identified for failure to implement operating procedure SOP 13502-2, "Control Rod Drive and Position Indication System," version 42. The licensee failed to follow procedural steps when resetting the control rod drive system BOU. As a result, control rods moved out-of-sequence when manually inserted by the operator at the controls (OATC).

Description:

On October 12, 2014, operators were conducting an infrequent evolution of Unit 2 reactor startup by boron dilution with all control rods fully withdrawn to support low power physics testing (LPPT). Following unit criticality, the OATC was directed to manually insert control rods to stabilize reactor power in the intermediate nuclear instrumentation range for LPPT data collection. The OATC manually inserted control rods about three steps and noticed control rod bank 'A' was inserting instead of the expected control rod bank 'D'. The OATC was unsure if the control rods should be withdrawn to the original position. Following discussion of the incorrect operation and unknown operational state of the rod control system between the OATC and the Shift Manager, it was decided to manually initiate a reactor trip. Control rod banks are moved in a pre-determined sequence and overlap because each bank has a different amount of rods, different insert location, and different neutron absorption worth that is taken into account when evaluating the expected core response during control rod movement. The BOU is the rod control system component that determined the movement sequence and overlap of the control rod banks. The licensee determined the erratic rod control system operation was due to an improper resetting of the BOU. Prior to inserting control rods for data collection, the BOU was reset using operating procedure 13502-2, "Control Rod Drive and Position Indication," version 42.

The procedure specified resetting of the BOU by pushing the 'BO+1' pushbutton (i.e.

upward direction) to set the BOU counter at 573 from 000. To perform the step quicker, the 'BO-1' pushbutton (i.e. downward direction) was used to set the BOU counter. Due to the equipment control logic, the BOU sequence function was not properly reset when the 'BO-1' pushbutton was used and resulted in the out-of-sequence control rod operation. Licensee corrective actions included crew stand downs, a human performance review board, and a note to procedure 13502-1/2, prior to the step for resetting the BOU to highlight the importance of using the 'BO+1' pushbutton.

Analysis:

The failure to properly implement SOP 13502-2 for resetting the rod control system BOU counter was a PD. The PD was more than minor because it was associated with the Configuration Control and Equipment Performance attributes of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that improper rod control system equipment lineup affected the licensee's ability to control reactivity. The inspectors evaluated the finding using Section C of Exhibit 2, "Mitigating Systems Screening Questions," of IMC 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012. The finding was determined to be Green because while the ability anticipate and control reactivity changes was reduced, it did not result in an inability to control reactivity in that boration capability and reactor trip functions remained available. The inspectors determined the finding had a cross-cutting aspect of "training" in the human performance area because the licensee had not provided sufficient practical training on the infrequent evolution of resetting the BOU.[H.9]

Enforcement:

Technical Specification 5.4.1.a, "Procedures," required, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A to Regulatory Guide 1.33, "Quality Assurance Program Requirements," of February 1978. Appendix A, Item 3.b, required procedures for startup and operation of the control rod drive system. Procedure SOP 13502-2, Control Rod Drive and Position Indication System, version 42, provided steps to adjust the BOU counter using the "BO+1" pushbutton. Contrary to the above, on October 12, 2014, the operators failed to correctly implement procedure SOP 13502-2 to reset the BOU counter using the "BO+1" pushbutton. As a result, control rod banks inserted out-of-sequence when manually inserted by the OATC during Unit 2 reactor startup activities which resulted in operators manually tripped the reactor. This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy. The violation was entered into the licensee's corrective action program as CR 879125.

.2 Failure To Restore Nuclear Service Cooling Water Manual Valves

Introduction:

A Green NRC-identified NCV of TS 5.4.1.a, "Procedures," was identified for the licensee's failure to properly implement administrative control procedure 10019-C, "Control of Safety Related Locked Valves," version 15.3. Two NSCW manual valves were not returned to their required 'locked-open' position after being throttled in support of outage activities.

Description:

On October 15, 2014, two days after Unit 2 had been returned to power operations, the inspectors identified that manual valve 2HV-11620, NSCW supply to the Unit 2 "B" train of the EDG jacket water (JW) heat exchanger (HX), was unlocked and throttled. The NSCW was considered to be in its standby alignment with the valve required to be 'locked-open'. The inspectors notified the licensee who proceeded to restore the valve to its fully open position and conducted an extent of condition that identified that valve 2HV-1836, ESF chiller condenser HX "B" train outlet valve, was also unlocked and throttled. The licensee determined the valves had been manipulated to support outage activities. Procedure 10019-C required manipulation and restoration of SR locked valves (SRLV) to be logged/tracked using procedure 11888-C, "Safety Related Locked Valve Manipulation Log," revision 10. The SRLV manipulation log records for these valves showed their initial manipulation had been logged per 11888-C on October 6, 2014; however, the valve restoration section had been improperly documented as 'N/A'. As a result, when operators reviewed the SRLV manipulation log, as part of returning the unit to power operations, the affected valves were not identified as requiring restoration.

The NSCW system removes heat from safety-related equipment during emergency operating conditions including the EDG JW HX and the ESF chiller condenser HX. These HXs have manual inlet and outlet isolation valves that were required to be secured (i.e. chained and locked) in the 'open' position to provide constant cooling water supply from the NSCW system. The licensee evaluated the throttled condition and determined there was adequate cooling water supply for these HXs to perform their safety function.

Analysis:

The licensee's failure to restore two NSCW manual valves to their required 'locked-open' position, as required by administrative procedure 10019-C, was a PD. The PD was more than minor because it was associated with the Equipment Performance and Configuration Control attributes of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that the valves' throttled condition reduced the cooling capability of the associated mitigating systems' HXs and the unsecured condition reduced the SRLV program's ability to control and maintain the configuration of valves required to be in a specified position. The inspectors evaluated the finding using Exhibit 2, "Mitigating Systems Screening Questions," of IMC 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012. The finding screened as Green because it was a deficiency that affected the heat removal design capability of the associated HXs, however; the flow rates associated with the valves' throttled condition were determined to be sufficient to maintain the supported systems (EDG and ESF chiller) operability. The inspectors determined the finding had a cross-cutting aspect of "documentation" in the human performance area because the organization provided inaccurate documentation of manipulation log sheet (11888-C) such that the individual reviewing the log sheet could not identify and take actions to restore the valves to their required position. [H.7]

Enforcement:

Technical Specification 5.4.1.a, "Procedures," required, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A to Regulatory Guide 1.33, "Quality Assurance Program Requirements," of February 1978. Appendix A, Item 1.c, required administrative procedures for equipment control (e.g. locking and tagging). Procedure 10019-C, "Control of Safety Related locked Valves," version 15.3, provided instructions to control manipulation and restoration of SRLV. Contrary to the above, the licensee failed to implement administrative procedures for equipment control. Between October 6, 2014, and October 15, 2014, the licensee failed to control two NSCW manual valves and restore these valves to their required 'locked-open' position. The licensee took immediate actions to restore the valves to their required 'locked-open' position. This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy. The violation was entered into the licensee's corrective action program as condition report 880824. (NCV 05000425/2014005-02, Failure to restore nuclear service cooling water manual valves to their required 'locked-open' position).

b. Findings

Introduction:

A Green self-revealing NCV of TS 5.4.1.a, "Procedures," was identified for the licensee's failure to properly implement maintenance procedures and work order instructions. Station personnel inadvertently removed the 2AD1CB safety-related battery charger from service while attempting to perform routine battery surveillance on the 2CD1B battery.

Description:

On December 17, 2014, the licensee had commenced a routine quarterly battery surveillance for the 2CD1B ('C' train) safety-related battery. After making initial battery checks in the 2CD1B battery room, electricians left the 2CD1B battery room and proceeded to notify main control room (MCR) operators, in accordance with procedure 28912-C, "92-Day Battery and Charger Inspection and Maintenance," version 66, prior to starting work. Following notification of the MCR, electricians and a station operator entered the 2AD1CB ('A' train) battery charger room and opened the supply power breaker for the 2AD1CB battery charger. Opening of the breaker actuated a trouble alarm, '2AD1CA/2AD1CB Trouble,' in the MCR, which prompted MCR operators to stop the work. As a result, the 2AD1CB battery charger was rendered inoperable for approximately 30 minutes while restoration activities were being performed. The licensee concluded that because the 2AD1CA battery charger was never removed from service while the 2AD1CB was out of service, no loss of safety function occurred.

Analysis:

The licensee's failure to implement maintenance instructions to remove the correct and identified battery charger (2CD1CB) was a performance deficiency. The performance deficiency was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

Specifically, the opening of the power supply breaker to the incorrect battery charger (2AD1CB) resulted in the charger being inoperable for a total of 30 minutes. The inspectors evaluated the finding using IMC 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," issued June 19, 2012. Because the inspectors answered "No" to all of the Exhibit 2, Mitigating Systems Screening Questions, the inspectors concluded that the finding was Green. The inspectors determined the finding had a cross-cutting aspect of "Challenge the Unknown" in the Human Performance area because the station operator proceeded in the face of uncertainty because the operator, which had been briefed on the correct battery charger to be removed from service (2CD1CB), did not question why electricians had directed him to the 2AD1CB battery charger. [H.11]

Enforcement:

Technical Specification 5.4.1.a, "Procedures," required, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A to Regulatory Guide 1.33, "Quality Assurance Program Requirements," of February 1978. Appendix A, Item 9 required, in part, that maintenance activities that can affect the performance of safety-related equipment should be performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. Contrary to the above, the licensee failed to perform safety-related station battery maintenance activities in accordance with written procedures and maintenance instructions. As a result, the 2AD1CB safety-related battery charger was rendered inoperable for a total of 30 minutes. This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy. This violation was entered into the licensee's corrective action program as CR 10002493.

.3 Semi-Annual Trend Review

The inspectors reviewed issues entered in the licensee's corrective action program and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors focused their review on human performance trends, but also considered the results of inspector daily condition report screenings, licensee trending efforts, and licensee human performance results. The review nominally considered the six-month period of July 2014 thru December 2014 although some examples extended beyond those dates when the scope of the trend warranted. The inspectors compared their results with the licensee's analysis of trends. Additionally, the inspectors reviewed the adequacy of corrective actions associated with a sample of the issues identified in the licensee's trend reports. The inspectors also reviewed corrective action documents that were processed by the licensee to identify potential adverse trends in the condition of structures, systems, and/or components as evidenced by acceptance of long-standing non-conforming or degraded conditions. Documents reviewed are listed in the Attachment.

4OA3 Event Follow-up

.1 (Closed) Licensee Event Report (LER) 05000425/2014-003-00: Unit 2 Manual Reactor Trip due to Out of Sequence Control Rod Movement

a. Inspection Scope

At approximately 0944 EST on October 12, 2014, while performing Unit 2 reactor startup, control rods were being manually inserted to stabilize reactor power for LPPT.

With the rod bank selector switch in 'Manual,' operators observed control bank 'A' insert instead of the expected 'D' bank. Operators took action to trip the reactor and stabilize the plant. Upon tripping the reactor, safety systems responded per design and the unit was stabilized in Mode 3. The cause of this event was incorrectly resetting of the rod control system BOU. The inspectors reviewed the LER, the associated condition report, apparent cause determination report, and subsequent action items.

b. Findings

The enforcement aspects of this finding are discussed in Section 1R20 of this report. No other findings were identified.
