INSPECTION RESULTS

Failure to Identify and Correct CAQ Associated with Failure of the 2B Seal Water Injection

Filter O-ring

Cornerstone Significance Cross-cutting Report

Aspect Section

Initiating Events Green NCV [P.2] - 71111.12 - 05000414/2018002-01 Evaluation Maintenance

Closed Effectiveness

A self-revealed Green NCV of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action,

was identified for the licensees failure to promptly identify and correct a condition adverse to

quality associated with the failure of 2B seal water injection filter (SWIF) O-ring. Specifically,

the licensees failure to implement corrective actions for the first failure of the O-ring on 2B

SWIF on March 12, 2018, led to a second failure of 2B SWIF O-ring on May 13, 2018.

Description:

On March 12, 2018, with Unit 2 at 100 percent power, control room operators entered AP-10,

Reactor Coolant Leak, due to indications of a charging line leak. Operators also entered

AP-8 Malfunction of Reactor Coolant Pump due to all four Unit 2 reactor coolant pump

(RCP) lower bearing and #1 seal outlet temperatures increasing. The RCS leak was

determined to be from the in-service 2B seal injection filter. Operators took immediate

actions to terminate the leak by isolating reactor coolant system letdown. Operators placed

the 2A SWIF in-service and restored seal water cooling to the RCPs. Shortly after the failure

it was determined that the leak was caused by failure of an O-ring on the 2B SWIF lid

housing. Following the transient the licensee entered the issue into the corrective action

program (CAP) and initiated actions to determine the cause.

On May 13, 2018, with Unit 2 at 100 percent power, the 2B SWIF O-ring failed causing an

RCS leak. Operators took similar actions to isolate the leak and placed the 2A SWIF in-

service. After further investigation, the licensee determined that the two failures were caused

by torque applied to the filter trunnion bolts during maintenance activities over time. This

resulted in a gap in the lid to the filter housing joint and allowed the O-ring to fail. After the

second failure, the licensee initiated actions to determine the appropriate torque value and

replace the trunnions. The licensee also initiated actions to ensure that no gap existed

between the lid and the filter housing for the SWIFs on both Units.

After the second failure the inspectors noted that the cause evaluation for the O-ring failure

on March 12, 2018, was not complete. The due date for the evaluation was changed twice

because the failed O-ring had not been sent for lab analysis. The inspectors concluded that

the failure to identify and correct the adverse condition associated with the March failure

contributed to the second failure on May 13, 2018.

Corrective Actions: The licensee took immediate corrective actions to isolate the RCS leak

and restore seal water cooling to the reactor coolant pumps by aligning the backup filter. The

licensee also initiated actions to identify the appropriate torque and revise maintenance

procedures verify no gap exists between the lid and filter housing.

Corrective Action Reference: CR 219084

12

Performance Assessment:

Performance Deficiency: The inspectors determined that the licensees failure to promptly

identify and correct a condition adverse to quality associated with the failure of 2B seal water

injection filter (SWIF) O-ring was a performance deficiency and a violation of 10 CFR Part 50,

Appendix B, Criterion XVI.

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

because it adversely affected the equipment performance attribute of the initiating events

cornerstone and its objective to limit the likelihood of events that upset plant stability and

challenge critical safety functions during shutdown as well as power operations. Specifically,

the failure to implement timely corrective actions for the failure of the 2B SWIF O-ring on

March 12, 2018, resulted in a second failure of the 2B SWIF O-ring on May 13, 2018.

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

Attachment 4, Initial Characterization of Findings, dated October 7, 2016, and IMC 0609,

Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated

June 19, 2012. The inspectors determined that the finding was of very low safety significance

(Green) because the finding would not have likely affected other systems used to mitigate a

LOCA resulting in a total loss of their function.

Cross-cutting Aspect: The inspectors determined the finding had a cross-cutting aspect of

evaluation in the area of problem identification and resolution, because the licensee failed to

thoroughly evaluate the failure of the 2B SWIF on March 12, 2018, to ensure that resolutions

addressed the cause of the O-ring failure.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, states that

measures shall be established to ensure that conditions adverse to quality, such as failures,

malfunctions, deficiencies, deviations, defective material and equipment, and non-

conformances are promptly identified and corrected.

Contrary to the above, the licensee failed to promptly identify and correct a condition adverse

to quality following the failure of the Unit 2, 2B SWIF O-ring on March 12, 2018. As a result,

Unit 2 experienced a second failure of the 2B SWIF O-ring on May 13, 2018. The licensee

took immediate corrective actions isolate the RCS leak and restore seal water cooling to the

reactor coolant pumps by aligning the backup filter.

Enforcement Action: This violation is being treated as a Non-Cited Violation, consistent with

Section 2.3.2 of the Enforcement Policy.

Assessments

The inspectors identified a Green NCV of 10 CFR Part 50, Appendix B, Criterion XVI,

Corrective Action, for the licensees failure to promptly identify and correct a condition

adverse to quality associated with low resistance readings for core exit thermocouples (CET)

identified during testing on January 30, 2018. Specifically, the licensee failed to declare two

CETs inoperable when resistance readings were outside of the acceptance criteria, until April

9, 2018.

Description:

On January 30, 2018, while performing thermocouple indication calibration check

(IP/2/A/3122/003B, Section 10.5, ICCM Train A Analog/Digital Internal Loop Calibration and

Power Supply Check/Replacement,) maintenance identified three CETs that didnt meet the

lead resistance to ground acceptance criteria and documented the values as unsatisfactory.

On February 2, 2018, CR 2181846 was generated to address the shorted CET readings. The

CR identified that three CETs had ground readings out of specification, but the actual

thermocouple was indicating properly for plant conditions. Maintenance verified via work order

(WO) 20177989 that the thermocouples were indicating properly and the CR was closed. On

April 7, 2018, CR 2196923 was generated as a result of inspectors follow-up questions. This

CR reviewed and evaluated operating experience that addressed potential CET water intrusion

that could be detected by the thermocouple to ground resistance checks. Maintenance (via

WO 20244802) took additional resistance CET/ground measurements closer to the reactor

vessel head, to eliminate potential erroneous readings and verify the acceptance criteria of the

CETs. These measurements identified unacceptable lead resistance to ground readings on

two CETs.

Corrective Action(s): Based on the unacceptable resistance readings, the license declared two

CETs inoperable and initiated corrective actions to address the CETs in a future refueling

outage.

Corrective Action Reference(s): CR 2204792

Performance Assessment:

Performance Deficiency: The inspectors determined that the licensees failure to promptly

identify and correct a condition adverse to quality associated with low resistance readings for

CET identified during testing, was a performance deficiency and a violation of 10 CFR Part 50,

Appendix B, Criterion XVI.

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

the equipment performance attribute of the mitigating systems cornerstone, and adversely

14

affected the cornerstone objective to ensure availability, reliability, and capability of systems

that respond to initiating events. Specifically, the licensee failed to declare two CETs

inoperable when resistance readings were outside of the acceptance criteria, until April 9,

2018.

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

Attachment 4, Initial Characterization of Findings, dated October 7, 2016, and IMC 0609,

Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated

June 19, 2012, The inspectors determined that the finding was of very low safety significance

(Green) because it was not a design deficiency; 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 than its

technical specification allowed outage time; and did not result in the loss of a high safety-

significant, non-technical specification train.

Cross-cutting Aspect: The finding had a cross-cutting aspect of evaluation in the area of

problem identification and resolution because the licensee failed to thoroughly evaluate

unacceptable resistance measurements for the CETs identified on January 30, 2018.

Specifically, the licensee did not use the corrective action program and acceptance criteria in

the maintenance procedure to evaluate the low resistance readings and the impact to CET

operability.

Enforcement:

Violation: 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requires that

measures shall be established to assure that conditions adverse to quality, such as failures,

malfunctions, deficiencies, deviations, defective material and equipment, and non-

conformances are promptly identified and corrected.

Contrary to the above, between January 30, 2018, and April 9, 2018, the licensee failed to

promptly identify and correct a condition adverse to quality associated with low resistance

readings for CETs identified during maintenance testing.

Enforcement Action: This violation is being treated as a NCV, consistent with Section 2.3.2 of

the Enforcement Policy.

Observation 71152 -

Problem Identification

and Resolution

The inspectors identified an adverse trend associated with emergent equipment issues with

emergency diesel generators. During the last assessment from January 2018 to June 2018,

all four of the Catawbas EDGs have had emergent equipment issues that have resulted in

extended periods of unavailability. The following items are examples of this trend:

On May 29, 2018, an auxiliary operator identified a jacket water leak on the 1B EDG while in

standby. Engineering calculated that the leak would increase to approximately 1.38 gph with

the diesel operating and would not meet the 7 day mission time if no action was taken. The

diesel was declared inoperable and returned to service on May 30, 2018, following repairs.

15

On June 11, 2018, during a post maintenance test of the 2A EDG, the output breaker 2ETA18

tripped open due to actuation of lockout relay 86D when trying to parallel and load. The

licensee determined that the issue was likely caused by recent maintenance. The 2A EDG was

declared operable on June 14, 2018, following repairs.

On June 19, 2018 during the performance of maintenance on the 1A EDG, the licensee

identified that power driven potentiometer (PDP) was not working. The diesel was declared

operable on June 20, 2018, following replacement of the PDP.

On June 26, 2018, during a scheduled surveillance test, the 2B EDG tripped due to a low lube

oil pressure non-emergency trip. The licensee implemented a compensatory action to remove

the non-emergency trip until repairs could be made and declared the diesel operable on June

27, 2018.

Unresolved Item Notice of Enforcement Discretion Granted from 71153 - Follow-

(Open) Technical Specifications Related to the Failure of the up of Events

2A EDG during Post-maintenance Test and Notices of

URI 05000414/2018-002-03 Enforcement

Discretion

Description:

As required by Inspection Manual Chapter 0410 Section 06.03.c, an unresolved item is being

opened associated with a Notice of Enforcement Discretion 18-2-001 related to approval to not

comply with TS requirements associated with the failure of the 2A emergency diesel generator

during post-maintenance testing on June 11, 2018.

On the basis of the staffs evaluation of the licensees request, the NRC concluded that

granting the NOED was consistent with the NRCs Enforcement Policy and had no adverse

impact on public health and safety or the environment. Therefore, as communicated orally to

the Duke staff on June 14, 2018, the NRC exercised enforcement discretion to not enforce

compliance with TS LCO 3.8.1 Condition G requirements that Catawba Nuclear Station, Units

2, be in Mode 2 by 10:08 a.m. EDT on June 14, 2018. Unit 2, Mode 3 entry was extended by

48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, to allow completion of repair on the 2A emergency diesel generator.

Planned Closure Action: Inspectors will review the licensees cause evaluation for this issue.

Licensee Actions: Duke completed repairs to the 2A emergency diesel generator such that the

condition causing the need for the NOED was corrected at 9:06 p.m. EDT on June 14, 2018.

Corrective Action Reference: CR 2212222
