[P.2] -

Evaluation 71114.05 The inspectors identified a Green, non-cited violation of 10 CFR 50.47(b)(14) for the failure to correct a deficiency identified in a 2018 multi-facility drill. Specifically, radiation protection staff did not provide a range of protective actions to emergency workers during a drill conducted October 10, 2018, and this same deficiency (weakness) was repeated during the November 6, 2019 biennial exercise. The inspectors determined that the licensees corrective actions for the issue were incomplete and did not address the extent of condition.

[H.12] - Avoid Complacency 71152 On September 14, 2020 a finding and associated non-cited violation was self-revealed when an operator removed a tag on a safety chiller. Specifically, after completing maintenance and declaring the chiller operable and while removing a Test in Progress tag, the operator accidentally repositioned a control power switch which tripped the chiller and rendered it inoperable until it could be recovered.

Additional Tracking Items

None.

PLANT STATUS

Unit 1 began the inspection period at 98 percent power in coast down operations for a planned upcoming refueling outage. On October 10, 2020, the licensee shut down Unit 1 for a planned refueling outage. On November 4, the licensee finished the refueling outage and restarted Unit 1. On November 6, 2020 while at 41 percent power the licensee shutdown the unit to repair a steam leak. After completing repairs on November 8, the licensee restarted Unit 1, and reached full power on November 11, 2020.

Unit 2 operated at or near full power for the 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.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the Coronavirus Disease 2019 (COVID-19), resident inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status, observed risk-significant activities; and completed on-site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on-site. The inspections documented below met the objectives and requirements for completion of the IP.

INSPECTION RESULTS

Failure to Critique Weaknesses During a Drill Cornerstone Significance Cross-Cutting Aspect Report Section Emergency Preparedness

Green NCV 05000445,05000446/2020004-01 Open/Closed

[H.1] -

Resources 71114.05 The inspectors identified a Green, non-cited violation of 10 CFR 50.47(b)(14) for the licensees failure to identify and correct weaknesses in emergency response organization performance during a full-scale drill conducted on October 10, 2018. Specifically, the licensee did not identify performance that would have precluded effective implementation of the emergency plan if it occurred during an actual radiological emergency.

Description:

The inspectors reviewed drill reports for a multi-facility drill that took place on October 10, 2018. One of the licensees semi-annual health physics drills required by the Emergency Plan was conducted in conjunction with the multi-facility drill. The following observations were made:

• Review of the report Health Physics, Semi Annual (EP37PA1XY1), October 10, 2018 (dated January 16, 2019) revealed that the evaluator/controller provided the health physics technicians with information on what samples they would take, and what would be the results of those samples. In addition, the evaluator/controller provided the technicians with information about what new radiological postings would need to be posted as a result of the sample results. This occurred because the health physics technicians were not taking any action on their own volition to demonstrate their knowledge, skills and abilities in analyzing the radiological conditions, nor to responding to the results of the analyses.

• Review of report Exercise Report, Red Team - October 10, 2018 (dated January 16, 2019) showed that all performance objectives associated with health physics and emergency worker exposure control were graded as satisfactory.

• In the listing of corrective action documentation initiated as part of the drill, documented in the multi-facility drill report, there were no actions initiated to address the intervention with the health physics technicians. There is no evidence it was evaluated in the critique process.

The Comanche Peak Nuclear Power Plant Emergency Plan (revision 43) states what the scope of evaluation was intended to include. Specifically, Section 12.2.5 states, in part, that health physics drills shallinvolve response to and analysis of simulated elevated airborne and liquid samples and direct radiation measurements in the environment. Actions to address the scope are to be addressed in the drills demonstration objectives. In the health physics drill report, the stated objectives involved evaluating the health physics technicians ability to perform analysis of various samples. Objectives to address their ability to respond to the results of these analyses correctly were not included in the licensees drill documentation.

In other related cases, not demonstrating the objectives of a drill based on ones knowledge and abilities is basis for unsatisfactory performance. For example, an emergency director that is prompted to provide a correct emergency classification is considered a failure to provide a prompt and accurate emergency action level (NEI 99-02, Revision 7, page 50). The licensees evaluation criteria was reviewed to see how it addresses such situations.

Record 9.1.2, Emergency Response Organization Drill/Exercise Evaluation Sheet, associated with document TRA-105, Emergency Preparedness Training, Revision 26, provides such criteria. In its Overall Evaluation Criteria, Item 3, it states that any performance which prevents an exercise objective from being met constitutes an overall evaluation of [sic] unsatisfactory. Not taking actions on ones volition towards meeting an objective prevents it from being demonstrated. Document TRA-105, Section 6.4.1, indicates that this evaluation criteria is used for drill/exercise performance evaluation for key ERO personnel. However, when asked by the inspector, licensee EP staff indicated that they had not developed similar evaluation criteria for non-key ERO personnel. Therefore, the licensee evaluator did not have a disposition path via evaluation criteria to document unsatisfactory performance in a consistent manner.

The inspectors concluded that health physics personnels failure to demonstrate the ability to analyze and respond to changing radiological conditions is performance that would have precluded effective implementation of the emergency plan during a radiological emergency.

The inspectors concluded that this constituted a weakness in emergency response organization performance. However, the licensee graded the performance as satisfactory. The licensees failure to identify the weakness and correct it is a performance deficiency.

Corrective Actions: The licensee entered these issues into the corrective action program.

Corrective Action References: CR-2020-008037

Performance Assessment:

Performance Deficiency: The licensees failure to correct weaknesses that occurred during an exercise was a performance deficiency which was within the licensees ability to foresee and correct. A weakness is defined in Section 2.0(o) of Inspection Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process, (dated September 22, 2015) as emergency response organization performance that would have prevented the effective implementation of the licensees emergency plan had the circumstances occurred. The EROs failure to assess changing radiological conditions and to provide a range of protection to emergency workers during the October 10, 2018 drill were weaknesses requiring correction.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the ERO Performance attribute of the Emergency Preparedness cornerstone and adversely affected the cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. The licensees ability to ensure that adequate measures will be taken to protect the health and safety of the public is degraded when weak emergency response organization performance is not corrected.

Significance: The inspectors assessed the significance of the finding using Appendix B, Emergency Preparedness SDP. Using Manual Chapter 0609, Significance Determination Process, Attachment 4, Tables 1, 2, and 3 worksheets (effective date October 7, 2016); and the corresponding Appendix B, Emergency Preparedness Significance Determination Process, Attachment 2 (issue date September 22, 2015); the performance deficiency was determined have very low safety significance (Green) because it was a failure to comply with NRC requirements, was not a loss of planning standard function, and was not a degraded risk significant planning standard function. The finding was not a loss of planning standard function because the licensee appropriately critiqued some weaknesses associated with risk-significant activities and the 10 CFR 50.47(b) planning standards.

Cross-Cutting Aspect: H.1 - Resources: Leaders ensure that personnel, equipment, procedures, and other resources are available and adequate to support nuclear safety. The finding had a cross-cutting aspect in the area of resources associated with human performance because the licensee failed to ensure procedures and processes for evaluating ERO performance were adequate. Specifically, no evaluation tool was provided to enable the evaluator to document prompted performance during drills and exercises as unsatisfactory. In addition, the demonstration objectives provided for the health physics drill documentation did not encompass the full required scope of performance described in the sites emergency plan. This de-emphasized the need of health physics technicians to demonstrate the ability to respond to results from various samples and did not emphasize to the evaluator that it was an ability that needed to be considered to assign satisfactory or unsatisfactory performance.

Enforcement:

Violation: Title 10 CFR 50.54(q)(2), requires, in part, that a power reactor licensee follow and maintain the effectiveness of an emergency plan which meets the requirements of Appendix E to 10 CFR Part 50 and the standards of 10 CFR 50.47(b). Title 10 CFR 50.47(b)(14)requires, in part, that deficiencies identified as a result of exercises or drills are (will be)corrected.

Contrary to the above, on January 16, 2019, the licensee failed to correct deficiencies identified as a result of exercises or drills. Specifically, the licensee failed to identify emergency response organization performance deficiencies (weaknesses) occurring during the October 10, 2018 full-scale drill and did not ensure correction of the weaknesses. There was no actual or potential safety significance because the weak performance occurred during a drill.

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

Failure to Correct Weaknesses During Drills and Exercises Cornerstone Significance Cross-Cutting Aspect Report Section Emergency Preparedness

Green NCV 05000445,05000446/2020004-02 Open/Closed

[P.2] -

Evaluation 71114.05 The inspectors identified a Green, non-cited violation of 10 CFR 50.47(b)(14) for the failure to correct a deficiency identified in a 2018 multi-facility drill. Specifically, radiation protection staff did not provide a range of protective actions to emergency workers during a drill conducted October 10, 2018, and this same deficiency (weakness) was repeated during the November 6, 2019 biennial exercise. The inspectors determined that the licensees corrective actions for the issue were incomplete and did not address the extent of condition.

Description:

During the November 6, 2019, exercise, the Operations Support Center (OSC)radiation protection (RP) staff failed to provide radiological briefings, including documenting radiological conditions on an Emergency Work Permit (EWP), for a Technical Support Center (TSC) engineer and several nuclear equipment operators (NEOs) dispatched to perform emergency work in the field.

The inspectors noted that a similar failure occurred during a multi-facility drill conducted on October 10, 2018, in which RP staff failed to provide radiological briefings for NEOs dispatched to perform emergency work as well. The 2018 issue was identified by the licensee in their critique process and documented in CR-2018-006928. The inspectors reviewed corrective actions following the October 10, 2018 drill. Licensee staff determined that the NEOs were directed to obtain a RP briefing at the radiological controlled area (RCA) access control desk prior to entering the plant, vice from the OSC RP coordinator. The inspectors asked if it was verified that the NEOs did indeed receive an RP briefing on the simulated radiological conditions where they were going. Also, if they did receive a briefing, how did its content compare to what the OSC RP coordinator would have provided in his/her briefing. Based on emergency preparedness staff review, there was no evidence that confirmed that the NEOs had received an RP briefing. As a result of this level of analysis, the only corrective action taken was to coach the drill teams shift manager to coordinate dispatch of NEOs to the field through the OSC in the future. Corrective action for this weakness was completed on January 30, 2019.

The licensee issued their report for the November 6, 2019 biennial exercise on December 15, 2019. As in the 2018 drill, the failure to provide radiological protection briefings was again identified by the licensee in their critique process as a weakness and documented in CR-2019-008800. However, the licensee failed to recognize that their corrective actions from the 2018 drill deficiency had been ineffective. During the licensees review of the 2019 exercise weakness, there were two opportunities to identify that ineffective corrective action had been implemented in response to the October 10, 2018 drill weakness:

• In the condition report CR-2019-008800 extent of condition review, the window of review for common identified weaknesses was confined to calendar year 2019.

• In another extent of condition review with condition report CR-2019-009542, based on an NRC-identified weakness in the November 6, 2019 exercise, the licensee reviewed another exercise weaknesses during the 2015 biennial exercise (CR-2019-009542; NRC Inspection Report 05000445, 05000446/2015002). This same weakness (failure to provide radiological protection briefings) was exhibited during that 2015 exercise, but licensee staff did not recognize this, missing an opportunity to expand the scope of their review for corrective action adequacy.

Therefore, the inspectors concluded that even though the failure to conduct radiological condition briefings for emergency teams was identified in exercises conducted in 2015, 2018 and 2019 exercises and entered into the corrective action program, the licensee failed to recognize that the 2019 weakness was recurring as a result of ineffective corrective actions after the 2018 weakness.

The inspectors concluded that a lack of appropriate and consistent radiological briefings for plant staff assisting mitigation and repair tasks could preclude the effective implementation of the emergency plan were that performance to occur in an actual radiological emergency, because emergency workers would not be informed about current conditions and consequently could receive excessive radiation exposure. Therefore, the inspectors concluded that the lack of radiological briefings for plant repair staff was a deficiency (weakness) which the licensee had failed to correct as required.

Corrective Actions: The licensee entered this issue into the corrective action program.

Corrective Action References: CR-2020-008038

Performance Assessment:

Performance Deficiency: The licensees failure to correct weaknesses that had been previously identified in prior drills or exercises was a performance deficiency which was within the licensees ability to foresee and correct. A weakness is defined in Section 2.0(o) of Inspection Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process, (dated September 22, 2015) as emergency response organization performance that would have prevented the effective implementation of the licensees emergency plan had the circumstances occurred.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the ERO Performance attribute of the Emergency Preparedness cornerstone and adversely affected the cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. The licensees ability to ensure that adequate measures will be taken to protect the health and safety of the public is degraded when weak emergency response organization performance is not corrected.

Significance: The inspectors assessed the significance of the finding using Appendix B, Emergency Preparedness SDP. Using Manual Chapter 0609, Significance Determination Process, Attachment 4, Tables 1, 2, and 3 worksheets (effective date October 7, 2016); and the corresponding Appendix B, Emergency Preparedness Significance Determination Process," Attachment 2 (issue date September 22, 2015); the performance deficiency was determined have very low safety significance (Green) because it was a failure to comply with NRC requirements, was not a loss of planning standard function, and was not a degraded risk significant planning standard function. The finding was not a loss of planning standard function because the licensee appropriately critiqued some weaknesses associated with risk-significant activities and the 10 CFR 50.47(b) planning standards.

Cross-Cutting Aspect: P.2 - Evaluation: The organization thoroughly evaluates issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. The finding had a cross-cutting aspect in the area of evaluation associated with problem identification and resolution because the licensee failed to evaluate the issue to ensure resolutions addressed causes and extent of condition. Specifically, after the October 2018 drill performance, the licensee did not confirm what actions were taken, thus ensuring that causes of the issue were not correctly identified. This resulted in ineffective corrective action delivered to a limited population of the emergency response organization.

Enforcement:

Violation: Title 10 CFR 50.54(q)(2), requires, in part, that a power reactor licensee follow and maintain the effectiveness of an emergency plan which meets the requirements of Appendix E to 10 CFR Part 50 and the standards of 10 CFR 50.47(b). Title 10 CFR 50.47(b)(14) requires, in part, that deficiencies identified as a result of exercises or drills are (will be) corrected.

Contrary to the above, between October 2018 and November 6, 2019, the licensee failed to correct deficiencies in their ERO performance identified as a result of exercises or drills. Specifically, the licensee did not correct failures to provide a range of protective measures to emergency workers by not providing radiological briefings to ERO staff assigned to assist in event mitigation and plant repair activities.

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

Error Caused Trip of Safety Chiller Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems

Green NCV 05000446/2020004-03 Open/Closed

[H.12] - Avoid Complacency 71152 On September 14, 2020 a finding and associated non-cited violation was self-revealed when an operator removed a tag on a safety chiller. Specifically, after completing maintenance and declaring the chiller operable and while removing a Test in Progress tag, the operator accidentally repositioned a control power switch which tripped the chiller and rendered it inoperable until it could be recovered.

Description:

On September 6, 2020, the licensee entered a planned maintenance outage to replace the compressor on the Unit 2 B safety chiller. During the maintenance outage, the licensee affixed a Test in Progress tag on a control switch for the safety chiller using a wax string directly on the toggle switch. A Test in Progress tag allows for non-operations personnel to reposition the switch when needed for maintenance or testing procedures. The site uses procedure STI-605.01, Work Control and Clearance Safety Tagging," Revision 6 to establish requirements and guidelines for hanging tags on components. While the procedure requires that tags be hung in a manner that the component on which the tag is hung is clear, the procedure does not provide details on the manner in which the tag is hung. In this instance, the tag was hung directly on a toggle switch by looping a string around the switch and pulling the string taut. This method of hanging the tag is consistent with past site practices and had resulted in unplanned switch repositioning in the past. After the safety chiller had been declared operable, the licensee sent a nuclear equipment operator (NEO) to remove the tag. The NEO reached up to remove the tag and this action led to the switch changing positions, removing control power to the safety chiller and causing an unplanned trip of the chiller.

Subsequent to the trip, the inspectors learned that the site had experienced chiller trips in the past and had covered the potential during the pre-job brief for clearing tags. Despite the history of tripping the chiller, the licensee did not develop an alternative strategy to hanging and removing tags. The inspectors walked down the safety chiller with the system operating procedure to understand steps needed to recover and restore the chiller. The estimated recovery of the chiller would take about ten minutes during which time the chiller would be inoperable and unavailable. The switch is located on the safety chiller control panel and is located just above head height. The location is accessible for switch operation but in an awkward location for tag hanging and removal. Although the switch was repositioned during tag removal, the inspectors noted that the switch could also be repositioned while attempting to read the tag.

The inspectors also noted that the licensee did not remove the tag until after the operations had restored the safety chiller to an operable status. Although not prohibited by procedure, if the same error occurred while removing tags from the toggle switch before the chiller was declared operable, it would have avoided rendering the chiller inoperable and having to enter into an unplanned technical specification action statement. The inspectors reviewed the licensee's program for human performance codified in STA-429, Human Performance Program, Revision 6, which establishes responsibilities for managers to mitigate conditions that lead to human error and individuals to take precautions before and during activities. Although, licensee staff was aware of the potential to reposition the switch, precautions were not sufficient to prevent switch repositioning.

Corrective Actions: The licensee took immediate action to restore the chiller after the Nuclear Equipment Operator informed the control room. Operations personnel are developing longer term actions to address the potential to reposition components during the tagging process.

Corrective Action References: The licensee entered the condition into the corrective action program as CR-2020-6686.

Performance Assessment:

Performance Deficiency: The licensee failed to take precautions sufficient to prevent unwanted operation of components while placing or removing tags. Specifically, the NEO repositioned a toggle switch while removing a tag on a safety chiller control power switch, rendering the chiller inoperable. The licensee human performance program, STA-429, establishes a standard to anticipate problems and take precautions prior to performance. However, precautions were not sufficient to preclude rendering the safety chiller inoperable.

Screening: The inspectors determined 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 to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors screened the finding in accordance with IMC 0612 appendix B dated December 12, 2019. Specifically, the maintenance planning coupled with procedures were not appropriate to the circumstances in that the use of the tagging procedure led to rendering the safety chiller inoperable.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors answered no to all the questions in IMC 0609, The Significance Determination Process (SDP) for Findings At-Power Findings Appendix A, Exhibit 2, dated December 13, 2019. Therefore, the finding is of very low safety significance, Green.

Cross-Cutting Aspect: H.12 - Avoid Complacency: Individuals recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Individuals implement appropriate error reduction tools. For this activity, licensee personnel recognized the potential for inadvertent component re-positioning during pre-job briefs but did not follow up in planning tag removal to preclude unplanned inoperability and unavailability.

Enforcement:

Violation: Technical Specification Section 5.4.1 requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. NRC Regulatory Guide 1.33, Revision 2, Appendix A, Section 9 addresses Procedures for Performing Maintenance," Section 9.a states that "Maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances."

Contrary to the above, on September 14, 2020, the licensee failed to properly preplan and perform maintenance that could affect safety-related equipment in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances.

Specifically, the planning and work instructions for the maintenance were not appropriate to the circumstances in that it failed to contain provisions to either preclude unwanted operation of a component while hanging or removing tags, or else to perform the tag removal at a time where it would not have the potential to affect safety-related chiller operability.

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

Observation: Human Performance Error Trend 71152 The inspectors reviewed the licensees corrective action program for potential adverse trends in human performance. The inspectors noted that the licensee had recognized and documented an adverse trend in human performance. Licensee analysis revealed a trend in a lack of proficiency in assigned tasks as well as self-imposed schedule pressure. The inspectors evaluated several of the issues and noted that many of the issues involved turnover of activities between shifts or interactions between onsite organizations. The inspectors concluded that these interfaces represent a source of errors that adversely impact human performance. Examples include:

During replacement of the compressor for the 2-06 safety chiller, night shift personnel closed lube oil filter block valves to inspect the jet oil pump. Day shift personnel did not recognize the valves were closed before starting the system and this resulted in high pressure and additional time to complete the planned work. This was determined to be a minor issue because it involved maintenance in progress.

During the unit 1 refueling outage, OPT-512A Residual Heat Removal and Safety Injection Subsystem Valve Test was turned over multiple times. During this procedure, night shift closed the A RHR pump discharge valve per procedure. This section of the procedure was not completed. Dayshift performed other sections of the procedure prior to completion of the partial section. This resulted in running the RHR pump for 20 minutes without establishing a flow path. Subsequent testing of the pump demonstrated the pump had not been damaged.

This was determined to be minor because the pump was not damaged and the plant conditions did not require the pump to be operable.

During filter testing of ventilation unit X-13, engineers in the field and operators in the control room failed to communicate effectively. As a result, operators secured the incorrect fan. Since the ventilation systems do not have a safety related function, there was no consequence to the error and it was determined to be a minor issue.

Following replacement of the 1-02 service water pump, engineering failed to establish new reference values in the surveillance procedure. Although engineering was aware that the pump would probably not test in the acceptable range, operations was not informed. This resulted in running the surveillance test and identifying the pump parameters were in the alert range despite having a new pump installed. Operators quickly recognized the procedure had not been updated with the new reference values and determined the pump remained capable of performing its intended safety function, so this was determined to be a minor issue.

The inspectors evaluated each of the issues and concluded each issue was of minor significance.
