Safety Conscious Work Environment

NRC inspectors conducted an assessment of the Safety Conscious Work Environment (SCWE) for the electrical maintenance department at North Anna Power Station. During the inspection, inspectors assessed whether issues exist that may represent challenges to the free flow of information, and whether underlying factors exist that would produce a reluctance to raise nuclear safety concerns. Interviews were conducted with a sampling of about eighty-five percent of the electrical maintenance group.

Based on inspection interviews and insights obtained from safety culture questionnaires the inspectors concluded that the conditions at the site, specifically in the electrical maintenance group, were conducive to a Safety Conscious Working Environment. Most personnel were comfortable using the corrective action program, and all were willing to report nuclear safety and other concerns using any and all processes available.

(1) The inspectors evaluated the Unit 2 1-E-A feedwater level transient and licensees response on February 7,

INSPECTION RESULTS

Failure to Assure Service Water Pump Sheds from Emergency Bus upon LOOP or SBO Cornerstone Significance Cross-cutting Aspect Report Section Mitigating Systems

Green NCV 05000338/2018001-01 Closed H.12 - Avoiding Complacency 71111.22 A self-revealing Green NCV of TS 5.4.1.a, was identified for the licensees failure to have adequate written procedures for assuring proper configuration control in areas affected by maintenance or plant modifications. Specifically, the licensee failed to detect and correct a disconnected lead from contact C1 on 1-SW-62-1SWEB03. This directly led to the failure of the 1B service water pump to shed from the 1J Emergency bus during performance of 1-PT-83.2 on March 11, 2018.

Description:

On March 11, 2018, while North Anna Unit 1 was in Mode 5 for a refueling outage, procedure 1-PT-83.2 Simulated Loss of Offsite Power (LOOP) and ESF Actuation, was performed as part of Surveillance Requirement 3.8.1.17b, Load Shedding from Emergency Buses. During the surveillance, the relevant acceptance criteria of 1-PT-83.2 contained in Steps 7.1.1.a, b were not met. Specifically, the acceptance criteria states that upon de-energization of the 1J emergency bus, under a simulated LOOP or SBO, nonsafety-related loads will automatically shed from the bus. This did not occur when the 1B service water (SW) pump failed to shed and remained on the emergency bus during auto start of the 1J EDG. The operators stopped the surveillance, declared the 1J EDG inoperable, and entered TS 3.8.1 Condition E, for the 1J EDG being inoperable for the performance of 1-PT-83.2.

Troubleshooting identified that a wire was disconnected from contact C1 on 1-SW-62-1SWEB03.

This condition would prevent the 62X relay from energizing and thereby, the trip relay coil on the 1B SW pump would not energize to shed the pump on a J emergency bus under voltage. The XS5 lead was re-landed, and 1-PT-83.2 was re-performed on March 12, 2018, with all acceptance criteria being met. The licensee determined the 1J EDG to have been inoperable but functional for this surveillance. It was determined that the SW pump was not a significant load on the bus that would cause the EDG to be non-functional. The operators exited TS 3.8.1, Condition E, prior to the Action Statement expiration.

Maintenance activities last occurred around the affected relay during design change DC-NA-13-00065, Replace U1 J Bus NGV relays, the week of September 9, 2016. Procedure 0-GEP-52, Conduct Post Modification Testing was in effect and was followed by personnel. This procedure is a guide for testing and monitoring equipment after a modification. The procedure lacked any provisions calling for the review of the work area to assure proper component configuration was restored.

Corrective Actions: Corrective actions planned and completed included performing troubleshooting of the equipment, an extended condition inspection of similar relays on both units, a revision to procedure 0-GEP-52 to include post maintenance review of the immediate job area, and an apparent cause evaluation. The licensee returned the affected system to normal configuration after troubleshooting identified the problem the day after the failed surveillance. The licensee also plans to submit a licensee event report to the NRC.

Corrective Action References: CRs 1001753 and 1091778

Performance Assessment:

Performance Deficiency: The inspectors concluded that the failure to provide adequate instructions in procedure 0-GEP-52 to include post maintenance review of the immediate job area to identify and correct incorrect equipment configurations was a performance deficiency. This issue was reasonably within the licensees ability to foresee and correct and should have been prevented.

Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the configuration control attribute of the Mitigating Systems cornerstones objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the procedure guidance failed to ensure the required configuration for proper load shedding of the 1B SW pump in the event of a LOOP or SBO.

Significance: The inspectors assessed the significance of the finding using IMC 0609, Appendix G, 1, Shutdown Operation Significance Determination Process (SDP), issued on May 5,2014, and determined it screened as Green because the deficiency did not cause the loss of operability or functionality of any structures, systems and components.

Cross-cutting Aspect: This finding had a cross-cutting aspect in the component of Avoid Complacency, H.12, because the organization did not recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Specifically, maintenance personnel did not inspect the immediate work area for challenges to configuration management, uninsulated loose hanging conductors and foreign material, nor submit a condition report for noted discrepancies.

Enforcement:

Violation: North Anna TS 5.4.1.a, requires, in part that, applicable procedures recommended in Regulatory Guide (RG) 1.33, Revision 2, Appendix A, February 1978, shall be established, implemented, and maintained. Section 9(e) of RG 1.33 calls for, procedures for control of modification work. Licensee procedure 0-GEP-52, governs post modification testing.

Contrary to the above, on March 11, 2018, it was identified that procedure 0-GEP-52 provided inadequate guidance to maintenance crews, following post modification testing on September 9, 2016. This resulted in leaving an electrical lead disconnected from maintenance performed on the 1J EDG rendering the EDG inoperable but functional.

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

EXIT MEETINGS AND DEBRIEFS

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring licensees performance

by conducting a quarterly integrated inspection at North Anna Power Station, Units 1 and 2 in

accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs

program for overseeing the safe operation of commercial nuclear power reactors. Refer to

https://www.nrc.gov/reactors/operating/oversight.html for more information. NRC and self-

revealed findings, violations, and additional items are summarized in the table below.

71111.22

A self-revealing Green non-cited violation (NCV) of Technical Specification (TS) 5.4.1.a, was

identified for the licensees failure to have adequate written procedures for assuring proper

configuration control in areas affected by maintenance or plant modifications. Specifically, the

licensee failed to detect and correct a disconnected lead from contact C1 on 1-SW-62-

1SWEB03. This directly led to the failure of the 1B service water (SW) pump to shed from the

1J emergency bus during performance of maintenance procedure 1-PT-83.2 on March 11, 2018.

PLANT STATUS

Unit 1 began the inspection period at 100 percent rated thermal power. On March 10, 2018, the

unit was shut down for a routine refuel outage and remained there for the remainder of the

inspection period.

Unit 2 operated at or near 100 percent rated thermal power for the entire inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in

effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with

their attached revision histories are located on the public website at http://www.nrc.gov/reading-

rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared

complete when the IP requirements most appropriate to the inspection activity were met

consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection

Program - Operations Phase. The inspectors reviewed selected procedures and records,

observed activities, and interviewed personnel to assess licensee performance and compliance

with Commission rules and regulations, license conditions, site procedures, and standards.

Safety Conscious Work Environment

NRC inspectors conducted an assessment of the Safety Conscious Work Environment

(SCWE) for the electrical maintenance department at North Anna Power Station. During the

inspection, inspectors assessed whether issues exist that may represent challenges to the

free flow of information, and whether underlying factors exist that would produce a

reluctance to raise nuclear safety concerns. Interviews were conducted with a sampling of

about eighty-five percent of the electrical maintenance group.

Based on inspection interviews and insights obtained from safety culture questionnaires the

inspectors concluded that the conditions at the site, specifically in the electrical maintenance

group, were conducive to a Safety Conscious Working Environment. Most personnel were

comfortable using the corrective action program, and all were willing to report nuclear safety

and other concerns using any and all processes available.

71111.22

A self-revealing Green NCV of TS 5.4.1.a, was identified for the licensees failure to have adequate

written procedures for assuring proper configuration control in areas affected by maintenance or

plant modifications. Specifically, the licensee failed to detect and correct a disconnected lead from

contact C1 on 1-SW-62-1SWEB03. This directly led to the failure of the 1B service water pump to

shed from the 1J Emergency bus during performance of 1-PT-83.2 on March 11, 2018.

Description: On March 11, 2018, while North Anna Unit 1 was in Mode 5 for a refueling outage,

procedure 1-PT-83.2 Simulated Loss of Offsite Power (LOOP) and ESF Actuation, was performed

as part of Surveillance Requirement 3.8.1.17b, Load Shedding from Emergency Buses. During

the surveillance, the relevant acceptance criteria of 1-PT-83.2 contained in Steps 7.1.1.a, b were

not met. Specifically, the acceptance criteria states that upon de-energization of the 1J emergency

bus, under a simulated LOOP or SBO, nonsafety-related loads will automatically shed from the

bus. This did not occur when the 1B service water (SW) pump failed to shed and remained on the

emergency bus during auto start of the 1J ED

G. The operators stopped the surveillance, declared

the 1J EDG inoperable, and entered TS 3.8.1 Condition E, for the 1J EDG being inoperable for the

performance of 1-PT-83.2.

Troubleshooting identified that a wire was disconnected from contact C1 on 1-SW-62-1SWEB03.

This condition would prevent the 62X relay from energizing and thereby, the trip relay coil on the 1B

SW pump would not energize to shed the pump on a J emergency bus under voltage. The XS5

lead was re-landed, and 1-PT-83.2 was re-performed on March 12, 2018, with all acceptance

criteria being met. The licensee determined the 1J EDG to have been inoperable but functional for

this surveillance. It was determined that the SW pump was not a significant load on the bus that

would cause the EDG to be non-functional. The operators exited TS 3.8.1, Condition E, prior to the

Action Statement expiration.

Maintenance activities last occurred around the affected relay during design change

DC-NA-13-00065, Replace U1 J Bus NGV relays, the week of September 9, 2016. Procedure

0-GEP-52, Conduct Post Modification Testing was in effect and was followed by personnel. This

procedure is a guide for testing and monitoring equipment after a modification. The procedure

lacked any provisions calling for the review of the work area to assure proper component

configuration was restored.

Corrective Actions: Corrective actions planned and completed included performing troubleshooting

of the equipment, an extended condition inspection of similar relays on both units, a revision to

procedure 0-GEP-52 to include post maintenance review of the immediate job area, and an

apparent cause evaluation. The licensee returned the affected system to normal configuration after

troubleshooting identified the problem the day after the failed surveillance. The licensee also plans

to submit a licensee event report to the NRC.

Corrective Action References: CRs 1001753 and 1091778

Performance Assessment:

Performance Deficiency: The inspectors concluded that the failure to provide adequate instructions

in procedure 0-GEP-52 to include post maintenance review of the immediate job area to identify

and correct incorrect equipment configurations was a performance deficiency. This issue was

reasonably within the licensees ability to foresee and correct and should have been prevented.

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

adversely affected the configuration control attribute of the Mitigating Systems cornerstones

objective to ensure the availability, reliability, and capability of systems that respond to initiating

events to prevent undesirable consequences (i.e., core damage). Specifically, the procedure

guidance failed to ensure the required configuration for proper load shedding of the 1B SW pump in

the event of a LOOP or SBO.

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

1, Shutdown Operation Significance Determination Process (SDP), issued on

May 5,2014, and determined it screened as Green because the deficiency did not cause the loss

of operability or functionality of any structures, systems and components.

Cross-cutting Aspect: This finding had a cross-cutting aspect in the component of Avoid

Complacency, H.12, because the organization did not recognize and plan for the possibility of

mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Specifically,

maintenance personnel did not inspect the immediate work area for challenges to configuration

management, uninsulated loose hanging conductors and foreign material, nor submit a condition

report for noted discrepancies.

Enforcement:

Violation: North Anna TS 5.4.1.a, requires, in part that, applicable procedures recommended in

Regulatory Guide (RG) 1.33, Revision 2, Appendix A, February 1978, shall be established,

implemented, and maintained. Section 9(e) of RG 1.33 calls for, procedures for control of

modification work. Licensee procedure 0-GEP-52, governs post modification testing.

Contrary to the above, on March 11, 2018, it was identified that procedure 0-GEP-52 provided

inadequate guidance to maintenance crews, following post modification testing on

September 9, 2016. This resulted in leaving an electrical lead disconnected from maintenance

performed on the 1J EDG rendering the EDG inoperable but functional.

Disposition: This violation is being treated as a non-cited violation, consistent with Section 2.3.2.a

of the Enforcement Policy.

EXIT MEETINGS AND DEBRIEFS

The inspectors confirmed that proprietary information was controlled to protect from public

disclosure.

On April 18, 2018 the inspector presented quarterly resident inspector inspection results to
