PLANT STATUS

Unit 1 operated at 100% rated thermal power (RTP) except for a reactor scram related to a turbine control valve partial closure transient on March 18, 2018. The unit returned to 100%

RTP on March 24, 2018, and operated at that level for the remainder of the inspection period.

Unit 2 operated at 100% RTP for the duration of the inspection period.

Unit 3 operated at 100% RTP until a reactor scram occurred on January 10, 2018, related to vibration-induced failure of hydraulic piping for the #2 turbine control valve. The unit returned to 100% power on January 15, 2018, and operated at that level until February 17, 2018. There were two unplanned downpowers during the inspection period due to #3 turbine control valve oscillations, one planned downpower for 3C reactor feed pump maintenance. From February 17, 2018, through March 31, 2018, Unit 3 was shutdown for a planned refueling outage U3R18.

71111.19 - Post Maintenance Testing Inadequate Post-Maintenance Testing of 4kV Breaker Stationary Switches

Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green [H.1] - 71111.19 Systems NCV 05000259, 260, 296/2018001-01 Resources Closed

Introduction:

A self-revealing, Green, NCV of 10 CFR Part 50, Appendix B, Criterion V, was identified when the licensee failed to perform an adequate post-maintenance test in accordance with NPG-SPP-06.3, Pre-/Post-Maintenance Testing. Specifically, the post maintenance testing on the 3C diesel generator output breaker did not ensure that all contacts on replacement stationary switches successfully changed state after installation.

Description:

On February 20, 2018, during the biannual performance of TS SR 3.8.1.9 for the 3C diesel generator, several automatic safety functions did not occur as designed. The 3B RHR, 3B Core Spray, and B1 RHRSW pumps did not automatically start after the 3C diesel generator output breaker closed in to the 3EC 4kV Shutdown Board. The Unit 3 480V Load Shed for Division II also did not occur. The degraded condition was determined to be the result of one pair of contacts on the diesel generator output breakers stationary switch failing to make up when the breaker closed in. Troubleshooting revealed that the stationary switch contact failed to make up because the associated actuating arm on the breaker failed to rotate the stationary switch sufficiently. Although these actuations did not automatically occur, they could have been accomplished manually once recognized by control room operators.

This particular contact was used in a part of the logic circuitry to signify that the diesel generator had successfully tied onto the board and was ready to accept the designed safety loads when there was an accident signal present and normal offsite power to the board was not available. The contact also initiates load shedding of non-essential 480 volt loads to prevent the diesel generator from being overloaded as the safety loads are automatically sequenced on. Additionally, because the 3B Core Spray pump would not have automatically started, the 3D Core Spray pump would also not have automatically started because of the design of the Core Spray initiation logic. The last time that the switch was known to be working correctly was during the last biannual surveillance test in February of 2016. The licensees past operability evaluation concluded that the 3C diesel generator, 3B and 3D Core Spray pumps, 3B RHR pump, B1 RHRSW pump, and Unit 3 480V Division II Load Shed Logic be considered inoperable from February 25, 2016, until February 20, 2018.

From a review of historical maintenance on this breaker, it was identified that the switch was replaced on March 3, 2016, via work order 116872223 as a 24 year preventative maintenance action; however, only a portion of the switchs contacts were tested for continuity during the post-maintenance tests. Inspectors identified that the testing performed did not satisfy the requirements of NPG-SPP-06.3, Pre-/Post-Maintenance Testing. Specifically, section 3.2.2.A.5 required that, PMTs for safety-related circuits shall include testing to ensure affected portions of the logic circuitry are tested if they were potentially affected.

Corrective Action(s): The breaker stationary switch was replaced and retested satisfactorily.

Corrective Action Reference(s): CR 1389131

Performance Assessment:

Performance Deficiency: The failure to perform adequate post maintenance testing on the 3C diesel generator output breaker in accordance with NPG-SPP-06.3, Pre-/Post-Maintenance Testing, was a performance deficiency.

Screening: The performance deficiency was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the performance deficiency caused the licensee to return a safety-related breaker to service that was later discovered to not be able to perform all of its safety related functions and rendered multiple supported components inoperable.

Significance: Using Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, the issue screened as requiring a detailed risk evaluation because it resulted in an actual loss of function of at least a single train for greater than its TS allowed outage time. An NRC Regional Senior Reactor Analyst (SRA) performed the detailed risk evaluation using SAPHIRE Version 8.1.6 and SPAR Model Version 8.50 for Unit 3. The SRA modeled the condition by assuming the EDG 3C Load Sequencer was failed for one year, which accounted for pump automatic start failures, and that manual start remained available. To account for potential manual start failures, the SRA performed a human reliability analysis using the SPAR-H method and adjusted the model to include a probability of operator failure to recover the sequencer. The dominant sequences (12), which accounted for 90% of the change, involved loss of offsite power with failure of various EDG combinations leading to a station blackout, loss of suppression pool cooling, and failure of low pressure injection. The result was a change in core damage frequency of less than 1E-7/year and was primarily mitigated by operator recovery. Because the change was less than 1E-7/year, no further analysis was needed for external events or large early release, and this finding was determined to be of very low safety significance (Green).

Cross Cutting Aspect: [H.1] - Resources. The apparent cause of the performance deficiency was that leaders did not ensure that plant procedures contained guidance for developing adequate post-maintenance tests for breaker stationary switch replacements.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion V, Instructions Procedures and Drawings, states, in part, that instructions shall include appropriate quantitative and qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to the above, on March 3, 2016, work order 116872223 did not contain post-maintenance test instructions with appropriate acceptance criteria for determining that the breaker stationary switch replacement had been satisfactorily accomplished.

Enforcement Actions: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

71124.01 - Radiological Hazard Assessment and Exposure Controls

Unauthorized Entry into a High Radiation Area (HRA)

Cornerstone Significance Cross-cutting Report Aspect Section Occupational Green [H.8] - 71124.01 Radiation Safety NCV 05000259, 260, 296/2018001-02 Procedure Closed Adherence

Introduction:

A self-revealing, Green, NCV of Technical Specification (TS) 5.7.1, was identified for a worker who entered a HRA without proper authorization. Specifically, the worker entered the Unit 3 A & C Residual Heat Removal (RHR) heat exchanger room using an incorrect Radiation Work Permit (RWP) and without being briefed on the radiological conditions.

Description:

On March 24, 2018, an electrician was assigned the job of installing a jumper on a component in the Unit 3 A & C RHR heat exchanger room. At the time, this area was posted Contaminated Area and High Radiation Area. The electrician logged into RWP 18370011, which did not allow entry into HRAs. The worker also bypassed the Radiation Protection (RP) desk and failed to receive a briefing on radiological conditions in the area.

The worker then dressed in anti-contamination clothing and proceeded past the HRA boundary into the room. He subsequently received a dose rate alarm of 82 mrem/hr, which exceeded the ED alarm setpoint of 60 mrem/hr, and immediately exited the area. A RP technician performed a follow up survey and confirmed the presence of HRA dose rates up to 300 mrem/hr at 30 cm.

Corrective Action(s): The licensee took immediate corrective actions including Radiologically Controlled Area (RCA) access restriction for the individual and initiation of an investigation of the event including surveys of the areas entered.

Corrective Action Reference(s): CR 1390579

Performance Assessment:

Performance Deficiency: The workers entry into a HRA without using an appropriate RWP and without being briefed on radiological conditions in the area, as required by TS 5.7.1, was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute of Human Performance and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation.

Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter (IMC) 0609 C, Occupational Radiation Safety Significance Determination Process. The finding was not related to As Low As Reasonably Achievable (ALARA)planning, nor did it involve an overexposure or substantial potential for overexposure, and the ability to assess dose was not compromised. Therefore, the inspectors determined the finding to be of very low safety significance (Green).

Cross-cutting Aspect: This finding involved the cross-cutting aspect of Human Performance, Procedural Adherence, because the event was a direct result of the workers failure to adhere to administrative requirements for HRA access.[H.8]

Enforcement:

Violation: Technical Specification 5.7.1 requires that access to HRAs be controlled by means of an RWP and entry into such areas shall be made only after dose rates in the area have been determined and entry personnel are knowledgeable of them. Contrary to this, on February 24, 2018, a licensee employee entered a posted high radiation area without proper RWP authorization and without being knowledgeable of the radiological conditions. Upon identification, the licensee immediately implemented RCA access restrictions for the individual and completed follow up surveys of the areas entered.

Enforcement Actions: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Implement Controls for Locked High Radiation Area (LHRA) Access Cornerstone Significance Cross-cutting Report Aspect Section Occupational Green [H.4] - 71124.01 Radiation Safety NCV 05000259/260/296/ 2018001-03 Teamwork Closed

Introduction:

A self-revealing, Green, NCV of TS 5.7.2, was identified for the failure to control access to a LHRA. Specifically, a worker installed and climbed a ladder in the Unit 3 drywell without RP personnel present. In doing so, the worker accessed an area with dose rates >1 rem/hr that had not been posted, locked, or surveyed prior to entry.

Description:

On February 18, 2018, a carpenter was directed by the RP Drywell Coordinator to install a ladder on the 563 elevation of the Unit 3 drywell near the A blower bank. The inspectors noted the ladder allowed access to an area that had not been surveyed by RP, was not posted or controlled as a LHRA, and no RP technician was present during the installation. While climbing up the ladder to complete a tie off, the carpenter received a dose rate alarm of 458 mrem/hr which exceeded the ED alarm setpoint of 400 mrem/hr. The ED alarm was seen by the remote monitoring station and a roving RP technician was dispatched to respond. The RP technician directed the carpenter to exit the drywell and report to RP.

The technician immediately performed a survey of the area accessible by the ladder and discovered dose rates up to 20 rem/hr on contact and 6 rem/hr at 30cm.

Corrective Action(s): The licensee took immediate corrective actions including posting a LHRA guard until appropriate controls could be implemented.

Corrective Action Reference(s): CR 1388425

Performance Assessment:

Performance Deficiency: The failure to post, lock, and survey the area prior to entry (or be escorted by RP), as required by TS 5.7.2, was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute of Human Performance and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation.

Significance: The inspectors assessed the significance of the finding using IMC 0609 C, Occupational Radiation Safety Significance Determination Process. The finding was not related to ALARA planning, nor did it involve an overexposure or substantial potential for overexposure (due to the use of remote monitoring), and the ability to assess dose was not compromised. Therefore, the inspectors determined the finding to be of very low safety significance (Green).

Cross-cutting Aspect: This finding involved the cross-cutting aspect of Human Performance, Teamwork, because the event was a direct result of poor coordination between work groups.

[H.4]

Enforcement:

Violation: Technical Specification 5.7.2 requires that HRAs with dose rates > 1 rem/hr at 30 cm, but less than 500 rad/hr at 1 m, be conspicuously posted and provided with a locked or continuously guarded door. TS 5.7.2 also requires that, except for personnel escorted by RP, entry into such areas be made only after dose rates in the area have been determined and entry personnel are knowledgeable of them. Contrary to this, on February 18, 2018, a licensee employee installed a ladder that allowed access to an area with dose rates > 1 rem/hr at 30 cm, but less than 500 rad/hr at 1 m, that was not posted or locked. In addition, the employee entered the area without a RP escort and prior to dose rates being determined.

The licensee took immediate corrective actions including posting a LHRA guard until appropriate controls could be implemented.

Enforcement Actions: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

Closed Selected Issues

Introduction:

A self-revealing, Green, NCV of 10 CFR Part 50, Appendix B, Criterion III, was identified when the licensee failed to ensure adequate control of valve design configurations in accordance with NPG-SPP-9.3, Plant Modifications and Engineering Change Control Revision 6. Specifically, the licensee machined a HPCI discharge valve contrary to original design and did not document the change.

Description:

On September 24, 2017, during the performance of the quarterly HPCI pump test an unintentional injection of colder condensate water into the reactor vessel occurred causing reactor power to be at 104% power for about 5 minutes. The injection was caused by a fractured actuator yoke nut that had developed during the June 2017 stroke test of 3-FCV-73-44 leaving the valve partially open. The licensee disassembled and inspected 3-FCV-73-44, and three other valves as a part of their extent of condition review.

During the disassembly of the valves, the licensee identified that the yoke nut flanges on two of the valves were found to be 1 versus that specified in the original vendor drawing which showed the flange was 1.25. The licensees evaluation determined that during past modifications of these valves the yoke nuts were received from the vendor and machined down to 1 without approval or documentation. Licensee extent of condition reviews identified another HPCI valve with an unapproved and undocumented 0.25 spacer below the bottom bearing set. Other deviations identified, were missing ball bearings and additional components in the bearing housing (bearing cage).

Corrective Action(s): As an immediate corrective action the licensee restored each of the valves to their original configurations in accordance with the vendor drawings.

Corrective Action Reference(s): CRs 1341458, 1357076, 1347334, and 1359556

Performance Assessment:

Performance Deficiency: The failure to ensure adequate control of valve design configurations, as required by NPG-SPP-9.3 revision 6, was a performance deficiency.

Specifically, the licensee machined a HPCI discharge valve contrary to original design and did not document the change.

Screening: The performance deficiency was more than minor because it was associated with the design control attribute and affected the associated cornerstone objective to ensure availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the resulting yoke nut and bearing configuration contributed to the failure of the valve, and prevented the valve from stroking fully closed.

Significance: Using Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, the issue screened as having very low safety significance (Green) because it was a deficiency that affected the design and qualification of safety related, HPCI valves, but operability was maintained.

Cross Cutting Aspect: No cross cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled.

NPG-SPP-9.3 establishes a process of administrative controls and regulatory/quality requirements for plant modifications and changes to engineering documents. NPG-SPP-9.3 Rev. 6, Step 3.1.9.A.1 states, in part, that vendor manuals and configuration control design documents affected by the change package have been revised or updated. Contrary to the above, in April 2012, the licensee failed to ensure that vendor manuals and other configuration control design documents affected by the change were revised or updated for 3-FCV-73-44.

Enforcement Actions: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

71152 - Annual (Closed) Inadequate Weak Link Analysis for Unit 2 and Unit Follow-up of

3, HPCI Discharge Valves Selected Issues

Description:

The subject URI was identified to determine if a performance deficiency exists regarding the adequacy of the weak link analysis for the valve and actuator of the HPCI Unit 2 and Unit 3 discharge valves. Inspectors reviewed the various historical weak link analyses for these valves. The original vendor analysis only included the results for the most limiting part in the valve rather than a complete documented analysis for each area analyzed. This minimal level of documentation met the licensees and regulatory standards. As a result, the licensee had no documentation that would cause engineers to believe that the valves yoke nut or yoke nut bearings would exceed their load ratings once the valves actuator thrust was increased in 2012. The valve vendor failed to recognize these loading limitations during their reviews that supported the licensees thrust modification. As a result of this discovery, Crane Nuclear Inc. issued a 10 CFR Part 21 Notification of Defect to the NRC on December 19, 2017.

Corrective Action Reference(s): CR 1344131 Closure Basis: Inspectors concluded that the defects described in the valve vendors notification were not reasonably within the licensees ability to foresee and did not represent a performance deficiency.

The subject URI was identified to determine if a performance deficiency existed regarding the adequacy of the commercial grade dedication of the valve yoke nut bearings in the HPCI discharge valves on Unit 2 and Unit 3.

Corrective Action Reference(s): CR 1358257 Closure Basis: Since the original thrust bearings were purchased/provided directly from the valve manufacturer, the licensees commercial grade dedication process was not applicable and there was no performance deficiency attributable to the licensee associated with the variation in bearing configuration. The acceptability of the valve manufacturers dedication process for the commercial grade bearings was not within the scope of this inspection.

Replacement bearings were procured after the as-found configurations were discovered to be different than the original design configuration. These replacement bearings were procured as commercial grade items and dedicated by the licensee prior to installation. No findings were identified.

==

Selected Issues

Description:

The subject URI was identified to determine if a performance deficiency exists regarding the adequacy of control room operators response to the September 24, 2017, Unit 3 inadvertent HPCI system injection into the reactor vessel.

Prior to the surveillance, reactor power had been reduced to 99.3 percent. The inadvertent injection caused reactor power to exceed the 100 percent licensed thermal power limit (RTP)and initiated an alarm for a reactor feedwater control system input failure. After the alarm, operators noticed that the HPCI check valve 3-73-45 was indicating open despite the upstream discharge valve 3-FCV-73-44 indicating closed. Once the operators diagnosed that HPCI injection was occurring, they initiated a HPCI turbine trip. The HPCI injection lasted approximately five minutes and reactor power stabilized at 104.8 percent. The 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> average RTP was less than 100%.

The inspectors reviewed the licensees performance analysis, Regulatory Information Summary (RIS) 2007-21, Adherence to Licensed Power Limits and IMC 0612, Appendix E, Examples of Minor Issues which discussed this circumstance. The training analysis concluded that the crew did not understand the expected plant response with a HPCI injection and thus were delayed in performing actions specified in AOI-3-1, Loss of Reactor Feedwater. Step 15 directed tripping the HPCI pump. The RIS stated that thermal power may rise slightly due to normal changes in plant parameters and operators are expected to take prompt corrective action to reduce thermal power once it is discovered to be above the licensed limit. Licensees may not intentionally operate or authorize operation above the maximum power level as specified in the license.

IMC0612, Appendix E found this circumstance to be one of minor significance when:

• Operators had performed the prerequisite power reduction and after realizing that thermal power had exceeded RTP, promptly decreased thermal power below the RTP.

• Operators made appropriate and timely adjustments to prevent the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> average CTP from exceeding RTP Corrective Action Reference(s): CR 1346991 Closure Basis: The Inspectors concluded that there was no intentional operation above RTP and that the operator response met the guidance in both the RIS 2017-21 and the IMC 0612, Appendix E.

Observation

==71152 - Annual Follow-up of Selected Issues

==

For the implementation of Unit 3 extended power uprate, inspectors assessed the licensees performance regarding problem identification and resolution against selected attributes listed in section 03.06 of Inspection Procedure 71152. Inspectors reviewed condition reports associated with extended power uprate to verify that problems were being promptly identified, evaluated, prioritized and resolved within the licensees corrective action program. Inspectors also reviewed the NRC Safety Evaluation for any regulatory commitments associated with extended power uprate and found that the licensee did not make any regulatory commitments.

Overall, inspectors found no licensee performance weaknesses during this review.

SUBJECT: BROWNS FERRY NUCLEAR PLANT - NRC INTEGRATED INSPECTION

REPORT 05000259/2018001, 05000260/2018001, AND 05000296/2018001

Dear Mr. Shea:

On March 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection

at your Browns Ferry Nuclear Plant, Units 1, 2, and 3. On April 20, 2018, the NRC inspectors

discussed the results of this inspection with Mr. W. Paulhardt and other members of your staff.

The results of this inspection are documented in the enclosed report.

NRC inspectors documented four findings which were determined to be of very low safety

significance (Green) in this report. All of these findings involved violations of NRC

requirements. Because of their very low safety significance, the NRC is treating these violations

as non-cited violations (NCVs) consistent with Section 2.3.2.a of the Enforcement Policy.

If you contest any of the 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

U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC

20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of

Enforcement,

U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the

NRC Resident Inspector at Browns Ferry Nuclear Plant.

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

U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk,

Washington, DC 20555-0001; with copies to the Regional Administrator, Region II, and the NRC

Resident Inspector at Browns Ferry Nuclear Plant.

J. Shea 2

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.

PLANT STATUS

Unit 1 operated at 100% rated thermal power (RTP) except for a reactor scram related to a

turbine control valve partial closure transient on March 18, 2018. The unit returned to 100%

RTP on March 24, 2018, and operated at that level for the remainder of the inspection period.

Unit 2 operated at 100% RTP for the duration of the inspection period.

Unit 3 operated at 100% RTP until a reactor scram occurred on January 10, 2018, related to

vibration-induced failure of hydraulic piping for the #2 turbine control valve. The unit returned to

100% power on January 15, 2018, and operated at that level until February 17, 2018. There

were two unplanned downpowers during the inspection period due to #3 turbine control valve

oscillations, one planned downpower for 3C reactor feed pump maintenance. From

February 17, 2018, through March 31, 2018, Unit 3 was shutdown for a planned refueling

outage U3R18.

71111.19 - Post Maintenance Testing

Inadequate Post-Maintenance Testing of 4kV Breaker Stationary Switches

Cornerstone Significance Cross-cutting Report

Aspect Section

Mitigating Green [H.1] - 71111.19

Systems NCV 05000259, 260, 296/2018001-01 Resources

Closed

Introduction: A self-revealing, Green, NCV of 10 CFR Part 50, Appendix B, Criterion V, was

identified when the licensee failed to perform an adequate post-maintenance test in

accordance with NPG-SPP-06.3, Pre-/Post-Maintenance Testing. Specifically, the post

maintenance testing on the 3C diesel generator output breaker did not ensure that all

contacts on replacement stationary switches successfully changed state after installation.

Description: On February 20, 2018, during the biannual performance of TS SR 3.8.1.9 for the

3C diesel generator, several automatic safety functions did not occur as designed. The 3B

RHR, 3B Core Spray, and B1 RHRSW pumps did not automatically start after the 3C diesel

generator output breaker closed in to the 3EC 4kV Shutdown Board. The Unit 3 480V Load

Shed for Division II also did not occur. The degraded condition was determined to be the

result of one pair of contacts on the diesel generator output breakers stationary switch failing

to make up when the breaker closed in. Troubleshooting revealed that the stationary switch

contact failed to make up because the associated actuating arm on the breaker failed to

rotate the stationary switch sufficiently. Although these actuations did not automatically

occur, they could have been accomplished manually once recognized by control room

operators.

This particular contact was used in a part of the logic circuitry to signify that the diesel

generator had successfully tied onto the board and was ready to accept the designed safety

loads when there was an accident signal present and normal offsite power to the board was

not available. The contact also initiates load shedding of non-essential 480 volt loads to

prevent the diesel generator from being overloaded as the safety loads are automatically

sequenced on. Additionally, because the 3B Core Spray pump would not have automatically

started, the 3D Core Spray pump would also not have automatically started because of the

design of the Core Spray initiation logic. The last time that the switch was known to be

working correctly was during the last biannual surveillance test in February of 2016. The

licensees past operability evaluation concluded that the 3C diesel generator, 3B and 3D Core

Spray pumps, 3B RHR pump, B1 RHRSW pump, and Unit 3 480V Division II Load Shed

Logic be considered inoperable from February 25, 2016, until February 20, 2018.

From a review of historical maintenance on this breaker, it was identified that the switch was

replaced on March 3, 2016, via work order 116872223 as a 24 year preventative maintenance

action; however, only a portion of the switchs contacts were tested for continuity during the

post-maintenance tests. Inspectors identified that the testing performed did not satisfy the

requirements of NPG-SPP-06.3, Pre-/Post-Maintenance Testing. Specifically, section

3.2.2.A.5 required that, PMTs for safety-related circuits shall include testing to ensure

affected portions of the logic circuitry are tested if they were potentially affected.

Corrective Action(s): The breaker stationary switch was replaced and retested satisfactorily.

Corrective Action Reference(s): CR 1389131

Performance Assessment:

Performance Deficiency: The failure to perform adequate post maintenance testing on the 3C

diesel generator output breaker in accordance with NPG-SPP-06.3, Pre-/Post-Maintenance

Testing, was a performance deficiency.

Screening: The performance deficiency was more than minor because it was associated with

the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected

the cornerstone objective of ensuring availability, reliability and capability of systems that

respond to initiating events to prevent undesirable consequences. Specifically, the

performance deficiency caused the licensee to return a safety-related breaker to service that

was later discovered to not be able to perform all of its safety related functions and rendered

multiple supported components inoperable.

Significance: Using Chapter 0609, Appendix A, The Significance Determination Process for

Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, the issue screened

as requiring a detailed risk evaluation because it resulted in an actual loss of function of at

least a single train for greater than its TS allowed outage time. An NRC Regional Senior

Reactor Analyst (SRA) performed the detailed risk evaluation using SAPHIRE Version 8.1.6

and SPAR Model Version 8.50 for Unit 3. The SRA modeled the condition by assuming the

EDG 3C Load Sequencer was failed for one year, which accounted for pump automatic start

failures, and that manual start remained available. To account for potential manual start

failures, the SRA performed a human reliability analysis using the SPAR-H method and

adjusted the model to include a probability of operator failure to recover the sequencer. The

dominant sequences (12), which accounted for 90% of the change, involved loss of offsite

power with failure of various EDG combinations leading to a station blackout, loss of

suppression pool cooling, and failure of low pressure injection. The result was a change in

core damage frequency of less than 1E-7/year and was primarily mitigated by operator

recovery. Because the change was less than 1E-7/year, no further analysis was needed for

external events or large early release, and this finding was determined to be of very low

safety significance (Green).

Cross Cutting Aspect: [H.1] - Resources. The apparent cause of the performance deficiency

was that leaders did not ensure that plant procedures contained guidance for developing

adequate post-maintenance tests for breaker stationary switch replacements.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion V, Instructions Procedures and

Drawings, states, in part, that instructions shall include appropriate quantitative and qualitative

acceptance criteria for determining that important activities have been satisfactorily

accomplished. Contrary to the above, on March 3, 2016, work order 116872223 did not

contain post-maintenance test instructions with appropriate acceptance criteria for

determining that the breaker stationary switch replacement had been satisfactorily

accomplished.

Enforcement Actions: This violation is being treated as a non-cited violation, consistent with

Section 2.3.2 of the Enforcement Policy.

Unauthorized Entry into a High Radiation Area (HRA)

Cornerstone Significance Cross-cutting Report

Aspect Section

Occupational Green [H.8] - 71124.01

Radiation Safety NCV 05000259, 260, 296/2018001-02 Procedure

Closed Adherence

Introduction: A self-revealing, Green, NCV of Technical Specification (TS) 5.7.1, was

identified for a worker who entered a HRA without proper authorization. Specifically, the

worker entered the Unit 3 A & C Residual Heat Removal (RHR) heat exchanger room using

an incorrect Radiation Work Permit (RWP) and without being briefed on the radiological

conditions.

Description: On March 24, 2018, an electrician was assigned the job of installing a jumper on

a component in the Unit 3 A & C RHR heat exchanger room. At the time, this area was

posted Contaminated Area and High Radiation Area. The electrician logged into RWP

18370011, which did not allow entry into HRAs. The worker also bypassed the Radiation

Protection (RP) desk and failed to receive a briefing on radiological conditions in the area.

The worker then dressed in anti-contamination clothing and proceeded past the HRA

boundary into the room. He subsequently received a dose rate alarm of 82 mrem/hr, which

exceeded the ED alarm setpoint of 60 mrem/hr, and immediately exited the area. A RP

technician performed a follow up survey and confirmed the presence of HRA dose rates up to

300 mrem/hr at 30 cm.

Corrective Action(s): The licensee took immediate corrective actions including Radiologically

Controlled Area (RCA) access restriction for the individual and initiation of an investigation of

the event including surveys of the areas entered.

Corrective Action Reference(s): CR 1390579

Performance Assessment:

Performance Deficiency: The workers entry into a HRA without using an appropriate RWP

and without being briefed on radiological conditions in the area, as required by TS 5.7.1, was

a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor

because it was associated with the Occupational Radiation Safety Cornerstone attribute of

Human Performance and adversely affected the cornerstone objective of ensuring adequate

protection of worker health and safety from exposure to radiation from radioactive material

during routine civilian nuclear reactor operation.

Significance: The inspectors assessed the significance of the finding using Inspection

Manual Chapter (IMC) 0609 C, Occupational Radiation Safety Significance Determination

Process. The finding was not related to As Low As Reasonably Achievable (ALARA)

planning, nor did it involve an overexposure or substantial potential for overexposure, and the

ability to assess dose was not compromised. Therefore, the inspectors determined the finding

to be of very low safety significance (Green).

Cross-cutting Aspect: This finding involved the cross-cutting aspect of Human Performance,

Procedural Adherence, because the event was a direct result of the workers failure to adhere

to administrative requirements for HRA access.[H.8]

Enforcement:

Violation: Technical Specification 5.7.1 requires that access to HRAs be controlled by means

of an RWP and entry into such areas shall be made only after dose rates in the area have

been determined and entry personnel are knowledgeable of them. Contrary to this, on

February 24, 2018, a licensee employee entered a posted high radiation area without proper

RWP authorization and without being knowledgeable of the radiological conditions. Upon

identification, the licensee immediately implemented RCA access restrictions for the

individual and completed follow up surveys of the areas entered.

Enforcement Actions: This violation is being treated as an NCV, consistent with Section 2.3.2

of the Enforcement Policy.

Introduction: A self-revealing, Green, NCV of TS 5.7.2, was identified for the failure to control

access to a LHR

A. Specifically, a worker installed and climbed a ladder in the Unit 3 drywell

without RP personnel present. In doing so, the worker accessed an area with dose rates >1

rem/hr that had not been posted, locked, or surveyed prior to entry.

Description: On February 18, 2018, a carpenter was directed by the RP Drywell Coordinator

to install a ladder on the 563 elevation of the Unit 3 drywell near the A blower bank. The

inspectors noted the ladder allowed access to an area that had not been surveyed by RP,

was not posted or controlled as a LHRA, and no RP technician was present during the

installation. While climbing up the ladder to complete a tie off, the carpenter received a dose

rate alarm of 458 mrem/hr which exceeded the ED alarm setpoint of 400 mrem/hr. The ED

alarm was seen by the remote monitoring station and a roving RP technician was dispatched

to respond. The RP technician directed the carpenter to exit the drywell and report to RP.

The technician immediately performed a survey of the area accessible by the ladder and

discovered dose rates up to 20 rem/hr on contact and 6 rem/hr at 30cm.

Corrective Action(s): The licensee took immediate corrective actions including posting a

LHRA guard until appropriate controls could be implemented.

Corrective Action Reference(s): CR 1388425

Performance Assessment:

Performance Deficiency: The failure to post, lock, and survey the area prior to entry (or be

escorted by RP), as required by TS 5.7.2, was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor

because it was associated with the Occupational Radiation Safety Cornerstone attribute of

Human Performance and adversely affected the cornerstone objective of ensuring adequate

protection of worker health and safety from exposure to radiation from radioactive material

during routine civilian nuclear reactor operation.

Significance: The inspectors assessed the significance of the finding using IMC 0609 C,

Occupational Radiation Safety Significance Determination Process. The finding was not

related to ALARA planning, nor did it involve an overexposure or substantial potential for

overexposure (due to the use of remote monitoring), and the ability to assess dose was not

compromised. Therefore, the inspectors determined the finding to be of very low safety

significance (Green).

Cross-cutting Aspect: This finding involved the cross-cutting aspect of Human Performance,

Teamwork, because the event was a direct result of poor coordination between work groups.

[H.4]

Enforcement:

Violation: Technical Specification 5.7.2 requires that HRAs with dose rates > 1 rem/hr at 30

cm, but less than 500 rad/hr at 1 m, be conspicuously posted and provided with a locked or

continuously guarded door. TS 5.7.2 also requires that, except for personnel escorted by RP,

entry into such areas be made only after dose rates in the area have been determined and

entry personnel are knowledgeable of them. Contrary to this, on February 18, 2018, a

licensee employee installed a ladder that allowed access to an area with dose rates > 1

rem/hr at 30 cm, but less than 500 rad/hr at 1 m, that was not posted or locked. In addition,

the employee entered the area without a RP escort and prior to dose rates being determined.

The licensee took immediate corrective actions including posting a LHRA guard until

appropriate controls could be implemented.

Enforcement Actions: This violation is being treated as an NCV, consistent with Section 2.3.2

of the Enforcement Policy.

71152 - Problem Identification and Resolution

Inadequate Configuration Control of HPCI Valve Design Issues

Cornerstone Significance Cross-cutting Report Section

Aspect

Mitigating Green None 71152 - Annual

Systems NCV 05000296/2018001-04 Follow-up of

Closed Selected Issues

Introduction: A self-revealing, Green, NCV of 10 CFR Part 50, Appendix B, Criterion III, was

identified when the licensee failed to ensure adequate control of valve design configurations

in accordance with NPG-SPP-9.3, Plant Modifications and Engineering Change Control

Revision 6. Specifically, the licensee machined a HPCI discharge valve contrary to original

design and did not document the change.

Description: On September 24, 2017, during the performance of the quarterly HPCI pump

test an unintentional injection of colder condensate water into the reactor vessel occurred

causing reactor power to be at 104% power for about 5 minutes. The injection was caused by

a fractured actuator yoke nut that had developed during the June 2017 stroke test of 3-FCV-

73-44 leaving the valve partially open. The licensee disassembled and inspected 3-FCV-73-

44, and three other valves as a part of their extent of condition review.

During the disassembly of the valves, the licensee identified that the yoke nut flanges on two

of the valves were found to be 1 versus that specified in the original vendor drawing which

showed the flange was 1.25. The licensees evaluation determined that during past

modifications of these valves the yoke nuts were received from the vendor and machined

down to 1 without approval or documentation. Licensee extent of condition reviews identified

another HPCI valve with an unapproved and undocumented 0.25 spacer below the bottom

bearing set. Other deviations identified, were missing ball bearings and additional

components in the bearing housing (bearing cage).

Corrective Action(s): As an immediate corrective action the licensee restored each of the

valves to their original configurations in accordance with the vendor drawings.

Corrective Action Reference(s): CRs 1341458, 1357076, 1347334, and 1359556

Performance Assessment:

Performance Deficiency: The failure to ensure adequate control of valve design

configurations, as required by NPG-SPP-9.3 revision 6, was a performance deficiency.

Specifically, the licensee machined a HPCI discharge valve contrary to original design and did

not document the change.

Screening: The performance deficiency was more than minor because it was associated with

the design control attribute and affected the associated cornerstone objective to ensure

availability, reliability and capability of systems that respond to initiating events to prevent

undesirable consequences. Specifically, the resulting yoke nut and bearing configuration

contributed to the failure of the valve, and prevented the valve from stroking fully closed.

Significance: Using Chapter 0609, Appendix A, The Significance Determination Process for

Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, the issue screened

as having very low safety significance (Green) because it was a deficiency that affected the

design and qualification of safety related, HPCI valves, but operability was maintained.

Cross Cutting Aspect: No cross cutting aspect was assigned to this finding because the

inspectors determined the finding did not reflect present licensee performance.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that

measures shall include provisions to assure that appropriate quality standards are specified

and included in design documents and that deviations from such standards are controlled.

NPG-SPP-9.3 establishes a process of administrative controls and regulatory/quality

requirements for plant modifications and changes to engineering documents. NPG-SPP-9.3

Rev. 6, Step 3.1.9.A.1 states, in part, that vendor manuals and configuration control design

documents affected by the change package have been revised or updated. Contrary to the

above, in April 2012, the licensee failed to ensure that vendor manuals and other

configuration control design documents affected by the change were revised or updated for 3-

FCV-73-44.

Enforcement Actions: This violation is being treated as an NCV, consistent with Section 2.3.2

of the Enforcement Policy.

(Closed) Inadequate Weak Link Analysis for Unit 2 and Unit Follow-up of

3, HPCI Discharge Valves Selected Issues

Description: The subject URI was identified to determine if a performance deficiency exists

regarding the adequacy of the weak link analysis for the valve and actuator of the HPCI Unit 2

and Unit 3 discharge valves. Inspectors reviewed the various historical weak link analyses for

these valves. The original vendor analysis only included the results for the most limiting part

in the valve rather than a complete documented analysis for each area analyzed. This

minimal level of documentation met the licensees and regulatory standards. As a result, the

licensee had no documentation that would cause engineers to believe that the valves yoke

nut or yoke nut bearings would exceed their load ratings once the valves actuator thrust was

increased in 2012. The valve vendor failed to recognize these loading limitations during their

reviews that supported the licensees thrust modification. As a result of this discovery, Crane

Nuclear Inc. issued a 10 CFR Part 21 Notification of Defect to the NRC on December 19,

2017.

Corrective Action Reference(s): CR 1344131

Closure Basis: Inspectors concluded that the defects described in the valve vendors

notification were not reasonably within the licensees ability to foresee and did not represent a

performance deficiency.

Unresolved Item URI 05000296/2017008-02, Potential Inadequate 71152 - Annual

(Closed) Commercial Grade Dedication of Components in Follow-up of

Safety Related Valves Selected Issues

Description: The subject URI was identified to determine if a performance deficiency existed

regarding the adequacy of the commercial grade dedication of the valve yoke nut bearings in

the HPCI discharge valves on Unit 2 and Unit 3.

Corrective Action Reference(s): CR 1358257

Closure Basis: Since the original thrust bearings were purchased/provided directly from the

valve manufacturer, the licensees commercial grade dedication process was not applicable

and there was no performance deficiency attributable to the licensee associated with the

variation in bearing configuration. The acceptability of the valve manufacturers dedication

process for the commercial grade bearings was not within the scope of this inspection.

Replacement bearings were procured after the as-found configurations were discovered to be

different than the original design configuration. These replacement bearings were procured

as commercial grade items and dedicated by the licensee prior to installation. No findings

were identified.

Unresolved Item URI 05000296/2017008-04, Potential Inadequate 71152 - Annual

(Closed) Operator Response to Inadvertent HPCI Injection Follow-up of

Selected Issues

Description: The subject URI was identified to determine if a performance deficiency exists

regarding the adequacy of control room operators response to the September 24, 2017, Unit

inadvertent HPCI system injection into the reactor vessel.

Prior to the surveillance, reactor power had been reduced to 99.3 percent. The inadvertent

injection caused reactor power to exceed the 100 percent licensed thermal power limit (RTP)

and initiated an alarm for a reactor feedwater control system input failure. After the alarm,

operators noticed that the HPCI check valve 3-73-45 was indicating open despite the

upstream discharge valve 3-FCV-73-44 indicating closed. Once the operators diagnosed that

HPCI injection was occurring, they initiated a HPCI turbine trip. The HPCI injection lasted

approximately five minutes and reactor power stabilized at 104.8 percent. The 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />

average RTP was less than 100%.

The inspectors reviewed the licensees performance analysis, Regulatory Information

Summary (RIS) 2007-21, Adherence to Licensed Power Limits and IMC 0612, Appendix E,

Examples of Minor Issues which discussed this circumstance. The training analysis concluded

that the crew did not understand the expected plant response with a HPCI injection and thus

were delayed in performing actions specified in AOI-3-1, Loss of Reactor Feedwater. Step 15

directed tripping the HPCI pump. The RIS stated that thermal power may rise slightly due to

normal changes in plant parameters and operators are expected to take prompt corrective

action to reduce thermal power once it is discovered to be above the licensed limit. Licensees

may not intentionally operate or authorize operation above the maximum power level as

specified in the license.

IMC0612, Appendix E found this circumstance to be one of minor significance when:

• Operators had performed the prerequisite power reduction and after realizing that

thermal power had exceeded RTP, promptly decreased thermal power below the RTP.

• Operators made appropriate and timely adjustments to prevent the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> average CTP

from exceeding RTP

Corrective Action Reference(s): CR 1346991

Closure Basis: The Inspectors concluded that there was no intentional operation above RTP

and that the operator response met the guidance in both the RIS 2017-21 and the IMC 0612,

Appendix E.

Observation 71152 - Annual Follow-up of Selected Issues

For the implementation of Unit 3 extended power uprate, inspectors assessed the licensees

performance regarding problem identification and resolution against selected attributes listed

in section 03.06 of Inspection Procedure 71152. Inspectors reviewed condition reports

associated with extended power uprate to verify that problems were being promptly identified,

evaluated, prioritized and resolved within the licensees corrective action program. Inspectors

also reviewed the NRC Safety Evaluation for any regulatory commitments associated with

extended power uprate and found that the licensee did not make any regulatory commitments.

Overall, inspectors found no licensee performance weaknesses during this review.

EXIT MEETINGS AND DEBRIEFS

disclosure.

• On January 25, 2018, the EC/FAC inspection results were presented to Steve Bono and

other members of the licensee staff

• On March 2, 2018, the radiation protection inspection and in-service inspection results were
