SUBJECT: JOSEPH M. FARLEY NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000348/2017001 AND 05000364/2017001; AND EXERCISE OF ENFORCEMENT DISCRETION

Dear Mr. Madison:

On March 31, 2017, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Joseph M. Farley Nuclear Plant, Units 1 and 2. On April 25, 2017, the NRC inspectors discussed the results of this inspection with you and other members of your staff. NRC inspectors documented one finding of very low safety significance (Green) in this report. This finding did not involve a violation of NRC requirements. Further, inspectors documented two licensee-identified violations, which were determined to be of very low safety significance, in this report. The NRC is treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy. If you disagree with the finding not associated with a regulatory requirement or 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 Farley Nuclear Plant.

In addition, contrary to Technical Specification (TS) 3.4.10, "Pressurizer Safety Valves," Unit 1 operated with a pressurizer safety valve inoperable for longer than the TS allowed completion time due to the safety valve lifting below the TS required minimum set pressure during its as-found, post-operational surveillance test. Although a violation of TS occurred, the violation was not within your ability to identify beforehand by reasonable licensee quality assurance measures or management controls. Therefore, the TS 3.4.10 violation was not associated with a licensee performance deficiency. The NRC concluded that the violation was of very low safety significance because there was not an adverse impact on the reactor coolant system over-pressurization protection safety function. Based on these facts, I have been authorized, after consultation with the Director, Office of Enforcement, and the Regional Administrator, to exercise enforcement discretion in accordance with Section 3.10 of the Enforcement Policy and refrain from issuing enforcement for the violation. This violation will not be considered in the assessment process or the NRC's Action Matrix. This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, "Public Inspections, Exemptions, Requests for Withholding."

Sincerely,/RA/

SUMMARY

IR 05000348/2017001; and 05000364/2017001, January 1, 2017, through March 31, 2017; Joseph M. Farley Nuclear Plant, Units 1 and 2, Event Follow-up

The report covered a three-month period of inspection by resident inspectors. There was one self-revealing finding 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 April 29, 2015. The cross-cutting aspects are determined using IMC 0310, "Aspects within the Cross-Cutting Areas," dated December 4, 2014. All violations of NRC requirements are dispositioned in accordance with the NRC's Enforcement Policy dated November 1, 2016. The NRC's program for overseeing the safe operations of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 6. Documents reviewed by the inspectors which are not identified in the Report Details are identified in the List of Documents Reviewed section of the Attachment.

Cornerstone: Initiating Events

Green.

A self-revealing finding was identified for the failure to maintain a preventive maintenance (PM) task to replace the main steam isolation valve (MSIV) test solenoid valves in accordance with the PM basis. As a result, test solenoid valve N1N11SV3369AG, which was installed for 13 years, failed and, combined with unknown additional air system leakage, led to an inadvertent closure of MSIV Q1N11HV3369A, resulting in a Unit 1 turbine trip/reactor trip with safety injection system actuation on October 1, 2016. The licensee's failure to perform the PM task to replace the MSIV test solenoids in accordance with the PM basis as required by licensee procedure NMP-ES-006, "Preventive Maintenance Implementation and Continuing Equipment Reliability Improvement," Ver. 8.1, section 6.1.1 was a performance deficiency (PD). The PD was more than minor because it was associated with the equipment performance attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during power operations.

This finding was of very low safety significance (Green) because the finding did not cause the loss of mitigation equipment relied upon to transition the plant to a stable shutdown condition following the reactor trip. The inspectors determined the finding had a cross-cutting aspect of Trending in the Problem Identification and Resolution (PI&R) area. Prior to this event, there were four documented failures of MSIV test solenoids valves in the last three years that did not get screened for programmatic or common cause issues [P.4].

(Section 4OA3.2)

Violations of very low safety significance that were identified by the licensee have been reviewed by the NRC. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.

REPORT DETAILS

Summary of Plant Status Unit 1 started the report period at approximately 100 percent rated thermal power (RTP) and maintained approximately 100 percent RTP throughout the report period.

Unit 2 started the report period at approximately 100 percent RTP. On January 3, a Unit 2 load reduction to 62 percent RTP occurred because of a loss of forced cooling of the main power transformer isophase bus duct. Following the event, Unit 2 stabilized at approximately 100 percent RTP on January 5 and maintained approximately 100 percent RTP throughout the remainder of the report period.

.1 (Closed) Licensee Event Report (LER) 05000348/2016-003-00, Pressurizer Safety Valve Setpoint Pressure Outside of Technical Specification Tolerance Band

a. Inspection Scope

This LER describes an issue with pressurizer safety valve Q1B13V0031B that was removed from service at Farley Nuclear Plant Unit 1 and tested at an offsite facility. As-found lift testing determined that the valve opened below the plant technical specification allowable lift pressure setting range. Firm evidence did not exist to identify when the failure to meet the lift setting occurred prior to the time of discovery at the test facility.

The licensee stated in the LER that valve seat leakage was the most likely cause of the as-found lift pressure. During the period of time that the valve was in service, there were no control room indications of seat leakage. Upon disassembly of the valve at the testing facility following testing, there was a small amount of boric acid observed in the valve, indicating there was some seat leakage while the valve was in service. The inspectors reviewed the event, associated documents, and licensee corrective actions.

The inspectors also evaluated the issue for any performance deficiencies.

b. Findings

Description:

On October 13, 2016, pressurizer safety valve Q1B13V0031B, removed from service at Farley Nuclear Plant Unit 1, was tested at an offsite facility. As-found lift testing determined that the valve opened at 2443 psig steam pressure, which was low outside the plant technical specification allowable lift setting range of 2460 psig to 2510 psig. The valve was installed at Farley Nuclear Plant Unit 1 on May 27, 2015, and remained in service during one fuel cycle until removal on October 11, 2016, when it was replaced with a similar operable refurbished valve. The licensee determined that the safety valve low as-found lift set-point did not have an adverse impact on reactor coolant system over-pressurization protection, since the valve continued to perform its reactor coolant system over-pressure protection function to prevent the system from exceeding the design pressure of 2485 psig. Therefore, the plant remained bounded by the accident analysis in the FSAR, based on the as-found condition.

Enforcement:

Farley Nuclear Plant Unit 1 Technical Specifications limiting condition for operation (LCO) 3.4.10, "Pressurizer Safety Valves," required three operable pressurizer safety valves with lift settings 2460 psig and 2510 psig, while the Unit was in modes 1, 2, and 3. With one pressurizer safety valve inoperable, Action Statement, Condition

"A". Required Action "A.1" required restoration of the valve to operable status within 15 minutes. If the required action and associated completion time is not met, Action Statement, Condition "B" required that the unit be in mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Contrary to this, the licensee determined the pressurizer safety valve setting was outside the TS limits longer than 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and 15 minutes during the operating cycle between May 27, 2015 and October 1, 2016, while the Unit was in modes 1, 2, and 3. TS compliance was restored by replacement of the pressurizer safety valve with an operable pressurizer safety valve prior to the beginning of operation for the next fuel cycle. The inspectors concluded that the violation was of very low safety significance (Green) and consistent with a Severity Level IV violation.

The NRC exercised enforcement discretion (Enforcement Action EA-17-041) for this violation in accordance with sections 2.2.4.d and 3.5 of the NRC's Enforcement Policy because the pressurizer safety valve as-found lift pressure was not within the licensee's ability to foresee and correct beforehand. The inspectors reached this conclusion due to the fact that during the period of time that the valve was in service, there were no control room indications of seat leakage. In addition, the low as-found lift set-point did not have an adverse impact on reactor coolant system over-pressurization protection, since the valve continued to perform its reactor coolant system over-pressure protection function to prevent the system from exceeding the design pressure of 2485 psig. This issue was entered into the licensee's corrective action program as condition report 10287017.

.2 (Closed) LER 05000348/2016-002-00, Automatic Reactor Trip and Safety Injection due to Closure of Main Steam Isolation Valve

a. Inspection Scope

On October 1, 2016, with Unit 1 at approximately 99 percent power, the plant experienced a trip of the main turbine and automatic reactor trip due to a sudden closure of a "1A" steam generator main steam isolation valve (MSIV). This caused a rapid pressure reduction in the remaining two steam generator steam lines which resulted in an automatic safety injection (SI). The emergency core cooling system (ECCS) injected into the reactor coolant system (RCS), auxiliary feedwater automatically started as expected, and all control rods fully inserted into the core. Unit 1 stabilized in Mode 3 with decay heat removed through the main condenser. The inspectors reviewed this LER, interviewed operations staff that were on shift during this event and reviewed the root cause determination report (CAR 266911). NCV 05000348/2016004-03 "Failure to Follow Procedure Resulted in Automatic Reactor Trip and Safety Injection," was documented in the Farley integrated inspection report 2016-004 (ADAMS ML17027A147) and was related to the event described in this LER.

b. Findings

Introduction:

A Green self-revealing finding was identified for the failure to maintain a preventive maintenance (PM) task to replace the main steam isolation valve (MSIV) test solenoid valves in accordance with the PM basis. As a result, test solenoid valve N1N11SV3369AG, which was installed for 13 years, failed and, combined with unknown additional air system leakage, led to an inadvertent closure of MSIV Q1N11HV3369A, resulting in a Unit 1 turbine trip/reactor trip with safety injection system actuation on October 1, 2016.

Description:

Following the event on October 1, 2016, Farley's root cause evaluation (CAR 266911) determined that a PM optimization effort conducted in 2004 cancelled PM task N1N11SV006 which would have replaced the MSIV test solenoid valves every seven years. The PM task was cancelled at that time because partial stroke testing of the MSIVs while at power was no longer being performed. However, a corrective action from a 2006 root cause report (CR2006103043) reinstated the partial stroke test of the MSIVs. This would have been an opportunity to re-establish the PM replacement of the test solenoid valves. Another opportunity to re-establish the replacement PM task was identified following the failure of test solenoid valve N1N11SV3370BG associated with MSIV 3370B on January 24, 2016. The subsequent equipment reliability checklist (CAR 262799) determined the cancellation of the PM task to replace the test solenoid valves was acceptable and that "13-plus years of service is acceptable performance." It was also recognized that the PM template expected these valves to be replaced approximately every 10 years under mild service conditions. These solenoid valves were installed in the main steam valve room and were subject to severe service conditions which likely supported the replacement frequency of seven years. Licensee procedure NMP-ES-006, "Preventive Maintenance Implementation and Continuing Equipment Reliability Improvement," Ver. 8.1, section 6.1.1 required PM tasks to be scheduled based on the PM basis frequency and equipment availability. Because the test solenoid valve (N1N11SV3369AG) was installed for longer than expected per the PM basis (template), it failed on October 1, 2016, and allowed significant air pressure to vent off from the MSIV actuator at a rate faster than the air supply could maintain. Since air pressure was required to open and maintain the MSIVs open, the loss of air pressure allowed the MSIV disc to drift into the flow stream of the main steam system which caused the sudden closure of MSIV 3369A, resulting in a Unit 1 turbine trip/reactor trip and a safety injection system actuation. The test solenoid valves for all MSIVs were replaced on Unit 1 during the refueling outage in October 2016. Both Unit 1 and Unit 2 test solenoid valves for all MSIVs were maintained isolated, except during MSIV partial stroke testing.

Analysis:

The licensee's failure to perform the PM task to replace the MSIV test solenoids in accordance with the PM basis as required by licensee procedure NMP-ES-006, "Preventive Maintenance Implementation and Continuing Equipment Reliability Improvement," Ver. 8.1, section 6.1.1 was a PD. The PD was more than minor because it was associated with the equipment performance attribute of the Initiating Events cornerstone objective and adversely affected that objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during power operations. Specifically, the failure to replace the test solenoid valves at a frequency in accordance with the PM template (basis), led to the test solenoid valve, N1N11SV3369AG, failure in service and the inadvertent closure of Unit 1 MSIV 3369A, which caused a turbine/reactor trip and safety injection system actuation on October 1, 2016. The significance of this finding was evaluated using IMC 0609, Appendix A, "The Significance Determination Process (SDP) for findings at Power," dated June 19, 2012.

This finding was determined to be of very low safety significance (Green) because, while this issue resulted in a reactor trip, it did not cause the loss of mitigation equipment relied upon to transition the plant from the onset of a trip to a stable shutdown condition.

The inspectors determined the finding had a cross-cutting aspect of Trending in the Problem Identification and Resolution (PI&R) area. Prior to this event, there were four documented failures of MSIV test solenoids valves in the last three years that did not get screened for programmatic or common cause issues. [P.4]

Enforcement:

Because the test solenoid valves for the associated MSIVs were not safety-related components, the finding was not associated with a violation of regulatory requirements. FIN 05000348/2017001-01, "Failure to perform PM task resulted in MSIV closure."

.3 (Closed) LER 05000348/2016-006-00, Manual Reactor Trip due to Loss of Speed Control on 1A Steam Generator Feed Pump

a. Inspection Scope

Unit 1 was in Mode 1 reducing power on November 8, 2016, to remove the main turbine generator from service, when at 32 percent power, operators manually tripped the reactor at 1331, before falling steam generator narrow range levels reached the automatic reactor trip set-point. All required safety systems were available and responded as expected and the unit was stabilized in Mode 3. At 1636 the licensee made a 4-hour non-emergency report to the NRC. The lowering steam generator levels resulted from the inability of the control room operators to raise the 1A feedwater pump speed after opening the recirculating control valve, due to failure of the pump speed controller. The failure of the pump speed controller was due to a failed operational amplifier on the speed reference adjust and speed controller (C2) card. The licensee investigated the card failure and documented the results of that evaluation in Corrective Action Report (CAR) 267990. The inspectors reviewed the licensee's condition report 10296282, the CAR, and associated documents, and discussed this issue with engineering and operations personnel. After the event, the control card manufacturer determined the operational amplifier failed on the new control card due to infant mortality. The C2 card was replaced, and the new card was verified to be within the required tolerance and satisfactory post maintenance testing was completed.

b. Findings

No findings were identified.

.4 (Closed) LER 05000348/2016-004-00, Unapproved Environmental Qualification Material Caused Inoperability of One Containment Cooling Train

a. Inspection Scope

Unit 1 was in mode 6 during a refueling outage on October 20, 2016, when the licensee discovered the motor field cables for the Unit 1 "C" containment cooler fan contained splice material that was not approved for use inside containment. The material was installed as part of a design change during the previous refueling outage. The unapproved splice material could have exposed the associated connectors to untested environmental conditions during a postulated accident. On December 19, 2016 the licensee submitted a Licensee Event Report (LER) to the NRC. The licensee investigated the installation of the unapproved splice kit and documented the results of that evaluation in Corrective Action Report (CAR) 267932. The inspectors reviewed the licensee's CAR, Condition Reports (CRs) 10288801 and 10317447, LER 2016-004, Human Performance Checklist NMP-GM-002-F31, and applicable environmental qualification (EQ) documentation. The unapproved splice material was removed and replaced with a qualified splice kit for use inside of containment and satisfactory post-maintenance testing was completed.

b. Findings

A licensee identified violation was documented in section

4OA7 of this report.

4OA5 Other Activities

.1 (Closed) Temporary Instruction (TI) 2515/192, Inspection of the Licensee's Interim Compensatory Measures Associated with the Open Phase Condition Design Vulnerabilities in Electric Power Systems

a. Inspection Scope

The objective of this performance based Temporary Instruction is to verify implementation of interim compensatory measures associated with an open phase condition design vulnerability in electric power system for operating reactors. The inspectors conducted an inspection to determine if the licensee had implemented the following interim compensatory measures. These compensatory measures are to remain in place until permanent automatic detection and protection schemes are installed and declared operable for open phase condition design vulnerability. The inspectors verified the licensee:

  • identified and discussed with plant staff the lessons learned from the open phase condition events at U.S. operating plants including the Byron Station open phase condition and its consequences. This included conducting operator training for promptly diagnosing, recognizing consequences, and responding to an open phase condition.
  • updated plant operating procedures to help operators promptly diagnose and respond to open phase conditions on off-site power sources credited for safe shutdown of the plant.
  • established and implemented periodic walkdown activities to inspect switchyard equipment such as insulators, disconnect switches, and transmission line and transformer connections associated with the offsite power circuits to detect a visible open phase condition.
  • ensured that routine maintenance and testing activities on switchyard components have been implemented and maintained. As part of the maintenance and testing activities, the licensee assessed and managed plant risk in accordance with 10 CFR 50.65(a) (4) requirements.

b. Findings

No findings were identified.

4OA6 Meetings, Including Exit On April 25, 2017, the resident inspectors presented the inspection results to Dennis

Madison and other members of the licensee's staff. The inspectors confirmed that proprietary information provided or examined during the inspection period was properly controlled.

4OA7 Licensee-Identified Violations The following violations of very low safety significance (Green) were identified by the licensee and were violations of NRC requirements which met the criteria of the NRC Enforcement Policy for being dispositioned as non-cited violations.

  • 10 CFR Part 50, Appendix B, Criterion III, "Design Control," required, in part, that measures be established for the selection and review for suitability of application of materials and parts that are essential to the safety-related functions of the structures, systems, and components. Contrary to those requirements, on October 20, 2016, the licensee discovered that an incorrect splice kit for the 1C containment cooler fan was installed on May 4, 2015. The design called for a bolted "V" splice, but the licensee installed a bolted in-line splice kit that was not suitable for use inside containment in accordance with Environment Qualification Package A-506152-0029E, Rev. 2. This error resulted in the inoperability of the 1C containment cooler during periods of the Unit 1 operating cycle 27 (May 7, 2015 - October 1, 2016).

Specifically, there were four periods during applicable modes (modes 1 - 4) when the 1C containment cooler was the selected cooler for train "B" for a period greater than seven days, which exceeded the allowed completion time per TS 3.6.6. Upon discovery of the incorrect containment cooler splice kit in-use, the licensee removed and replaced the bolted in-line splice with an approved bolted "V" splice kit. The repairs were completed and tested on October 25, 2016. The finding was determined to be Green, very low safety significance, because the finding did not represent an actual open pathway in the physical integrity of the reactor containment, nor did it involve an actual reduction in function of the hydrogen igniters using the Barrier Integrity screening questions. The licensee entered this issue into the corrective action program as CRs 10288801 and 10317447.

  • 10 CFR 50.65 (a)(1) required, in part, that holders of an operating license shall monitor the performance or condition of structures, systems and components (SSCs) within the scope of the rule as defined by 10 CFR 50.65 (b), against licensee established goals, in a manner sufficient to provide reasonable assurance that such SSCs are capable of fulfilling their intended functions. Such goals shall be established commensurate with safety. When the performance or condition of a SSC does not meet established goals, appropriate corrective action shall be taken. Contrary to the above, from October 22, 2015, the time that maintenance rule (MR) function P12-F02, 1A reactor makeup water system was placed in (a)(1) status, the licensee did not take appropriate corrective actions when performance of the 1A reactor make up water system did not meet licensee established goals and did not repair the cause of previous 1A reactor makeup water pump failures. According to the MR (a)(1) plan EVAL-F-P12-02947 dated October 22, 2015, work order SNC59263 to flowscan pressure control valve (PCV) 510 and calibrate/replace pressure controller 510 was due on Febuary 28, 2016. That work order was not completed on time as discussed in the (a)(1) plan and on June 28, 2016, CR10241662 requested a new work order to make the necessary repairs to PCV-510. As a result, a corrective maintenance work order SNC799691 was generated but was later cancelled. Further discussed in the (a)(1) plan from October 2015 was technical evaluation (TE) 915229. This TE documented the creation of work orders SNC55726 and SNC55728 as a completed corrective action.

However, those corrective maintenance work orders were cancelled as part of a WO backlog reduction effort in September 2015. Preventive maintenance work order SNC59263 remained open, but was rescheduled for May 2018. CR10322037 was written by the system engineer and WO SNC59263 was rescheduled for July 2017.

On February 8, 2017, CR10328144 identified degradation of PCV-510 and a corrective maintenance WO (SNC 844008) was approved to repair this valve in April 2017. An equipment outage on the 1A reactor makeup water pump occurred during the week March 13, 2017, but the (a)(1) corrective action WO SNC59263 was not included in this equipment outage. This finding was determined be Green, very low safety significance, because the finding was not a deficiency affecting the design or qualification of a mitigating SSC, did not represent a loss of system and/or function, did not represent an actual loss of function of at least a single Train for longer its TS allowed outage time, and did not represent an actual loss of function of one or more non-TS trains of equipment designated as high safety-significant.
