PLANT STATUS

Wolf Creek Generating Station began the inspection period operating at full power. On May 24, 2019, licensee conducted an unplanned power reduction to approximately 96 percent power following the loss of the start-up transformer, due to an external fault between cable terminations. After that event, the plant operated at or near full power for the rest of the 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 performed plant status activities described in IMC 2515 Appendix D, Plant Status and conducted routine reviews using IP 71152, Problem Identification and Resolution. 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.

71152 - Problem Identification and

Resolution of Inspection Report 05000482/2018003.

INSPECTION RESULTS

Observation: Semiannual Trend Review 71152 The inspectors reviewed the licensees corrective action program for trends in the area of SCWE.

SCWE

The NRC conducted several inspections during the assessment period to assess the corrective actions taken to address the existing SCWE cross-cutting theme, including observations made in a Problem Identification and Resolution Inspection (Inspection Report 05000482/2018007 (ADAMS ML18218A265)) and a quarterly Integrated Inspection (Report 05000482/2018004 (ADAMS ML19042A089)). Based on these inspections and review of the licensees actions taken and planned, as well as the issuance of the violation of 10 CFR 50.7, the NRC determined that a theme in the SCWE area continued to exist.

Consistent with NRC guidance, the licensees progress on addressing the SCWE theme will be reviewed on a semiannual basis. During the current inspection, the inspectors review included consideration of previous NRC reviews of the licensees progress in addressing the SCWE theme, recent actions that Wolf Creek has completed or planned to address the cross-cutting theme in the SCWE area, and consideration of recent enforcement actions taken by the NRC.

The inspectors reviewed approximately 60 condition reports during this effort that were directly or potentially related to SCWE. The number of condition reports from June 2018 to December 2018 were compared against the number of SCWE condition reports that were written between January 2019 to June 2019, the specific content of the SCWE condition reports was evaluated, and the number of anonymous SCWE condition reports was assessed.

Assessment

With regard to actions taken to address the cross-cutting theme in the SCWE area, it appears that the licensee is applying the corrective actions as described in their identified plan. Many of the corrective actions taken include senior management presentations to the staff (referred to as Blitzes), group training for managers, group training for employees, and procedural changes. These activities (Blitzes, training and procedural changes) are not yet complete, and the licensee has not yet evaluated the effectiveness of these actions. The inspectors reviewed the licensees actions and did not identify any significant concerns.

Regarding the trend of SCWE-related condition reports, there did appear to be an increase in number compared to previous time periods. Upon review, the inspectors determined that the increase in number of SCWE-related condition reports coincided with the scheduled management presentations on SCWE (Blitzes), indicating that the topic was gaining more attention across the site. A closer review of these condition reports identified a number that would fall into the Non-Condition Adverse to Quality (NCAQ) category. The inspectors concluded that the increase in SCWE-related condition reports was not unusual and did not represent a degradation in the licensees SCWE. However, the inspectors noted that the number of anonymous condition reports did not appear to decrease, indicating that there are still employees who do not feel comfortable bringing their concerns directly to their management.

Observation: Semiannual Trend Review 71152 The inspectors reviewed the licensees corrective action program for trends in human performance and equipment reliability that might be indicative of more significant safety issues.

Human Performance

During this past quarter, the licensee experienced multiple human performance issues associated with procedure implementation. The following condition reports were written for events that have occurred in the quarter:

  • CR 132789 and CR 132791 - On May 29, 2019, during maintenance work to replace batteries associated with an uninterruptable power supply for security related facilities, the site experienced a loss of power to the main security building. Human error was determined to be the cause. Specifically, while implementing maintenance procedures to align equipment for battery replacement, technicians accidentally disconnected power to the main security building.
  • CR 132303: On May 9, 2019, while performing chemical and volume control system diaphragm valve torqueing and post maintenance tests for the boron thermal regeneration system (BTRS) in preparation for the outage, operators identified that letdown flow unexpectedly went to 0 gallons per minute during a valve stroke. Logs indicate that operators returned the subject valve to the closed position, which restored letdown flow to the initial value. Further investigation revealed that the procedure did not direct operators to place the subject valve in manual. The cause was determined to be lack of adequate rigor during the procedure change process.
  • CR 132451: On May 8, 2019, maintenance technicians completed a clean and inspect work order in the wrong cabinet on the BTRS. The technicians were signed on to the appropriate clearance order for the work order they were using. However, the labeling for the two cabinets was unclear, and the technicians did not stop to resolve which was the correct cabinet, which led to the technicians performing work in the wrong cabinet.
  • CR 131452: On April 10, 2019, while performing a post-maintenance test on the B instrument air compressor, a control room operator failed to verify that the train B essential service water supply valve to the B instrument air compressor was open. The compressor had been filled and vented, but there was no cooling water flow through the compressor. Thus, when the compressor was started and loaded, it tripped on high temperature.

On May 16, 2019, CR132471 was initiated by the licensee to document an adverse trend in maintenance performance. Condition Reports 132451 and 132791 were added to CR 132471 as examples for the trend analysis. This condition report concluded that the maintenance organization demonstrated less than adequate performance due to inattention to detail and mis-judgement. It also concluded that individuals rationalized proceeding in the face of uncertainty instead of stopping when unsure. Furthermore, on April 11, 2019, CR 131489 was initiated to document a site trend for failure to use effective human performance error reduction tools. All of the above mentioned human performance issues have a commonality of a lack of attention to detail in implementing procedures.

Overall, inspectors determined that the licensee has adequately captured the above issues in their corrective action program. Also, the licensee has taken timely action to identify a low-level trend in human performance and implement corrective actions.

Equipment Reliability - Communications Issues with Radiation Monitors

In May and June 2019 the licensee experienced several instances of system communications failures that led to the inoperability of safety-related radiation monitors. These issues were documented in the following condition reports, that were written within one month:

  • CR 132680: On May 23, 2019, the train A fuel building exhaust radiation monitor (GGRE0027) was declared inoperable due to having lost communications from field computer point (RM-80) to the control and display panel in the control room (RM-23).
  • CR 133199: On June 13, 2019, operators declared the train B fuel building exhaust radiation monitor (GGRE0028) inoperable due to communications failure experienced while performing channel operational testing on GGRE0028.
  • CR 133314: On June 19, 2019, the licensee identified that five radiation monitors had exceeded their established Maintenance Rule performance criteria for cumulative unavailability. The three-aforementioned safety-related radiation monitors were included in the five radiation monitors reviewed in this condition report.

The above-mentioned issues with the GGRE0027, GGRE0028, and GKRE0005 radiation monitors, have a commonality of communications failure. These failures indicate a low-level trend for decreasing radiation monitor reliability combined with a trend of increased unavailability time for radiation monitors. The inspectors noted that these trends appeared to indicate a lack of priority for radiation monitor repair.

Failure to Submit a Revision to Section 9.1.4.3 of the Wolf Creek Updated Final Safety Analysis Report Cornerstone Severity Cross-Cutting Aspect Report Section Not Applicable Severity Level IV NCV 05000482/2019002-01 Open/Closed Not Applicable 71111.17T The inspectors identified a Severity Level IV, non-cited violation of 10 CFR 50.71(e)(4) for the licensees failure to file a revision of Section 9.1.4.3, Safety Evaluation, of the Wolf Creek Final Safety Analysis Report, which reflected changes to the reactor head load drop analysis.

Description:

Section 9.1.4.3 of the Wolf Creek Updated Final Safety Analysis Report contains the safety evaluation for various fuel handling system accidents. One of the fuel handling accidents postulated is a fuel handling accident caused by a drop of the reactor vessel head caused by failure of the polar crane. Updated Final Safety Analysis Report (UFSAR),page 9.1-53 to page 9.1-70, contain the analysis methodology, accident cases, input assumptions such as weight and dissipation factors, and results for the postulated drop of the reactor vessel head assembly.

In November 2017 the licensee approved Calculation 0720517.01-C-001, Wolf Creek Generating Station (WCGS) Simplified Head Assembly (SHA) Drop Analysis, Revision 1. This calculation updated the previous reactor vessel head drop analysis to include an increased reactor vessel head assembly weight due to insulation changes and addition of canopy seal clamp assemblies. Additionally, inputs for the reactor vessel weight, reactor vessel nozzle stiffness, support stiffness, and energy dissipation factors were changed to produce more conservative results. These analyses were performed with two new accident cases at drop heights of 28.5 feet and 32 feet above the vessel flange, respectively. The change to design inputs resulted in the calculation results being more conservative than the results reflected in the UFSAR Section 9.1.4.3 for bending stress, vessel nozzle displacement, and support displacement. To support the calculation changes, the licensee completed a 10 CFR 50.59 safety evaluation (approved in December 2017) to determine that the change in design inputs and results would not require a license amendment from the NRC.

Step 6.2.1 of Procedure AP 26A-003, 10 CFR 50.59 Reviews, directs the licensee to initiate a change to the UFSAR if the proposed change causes the existing information in the UFSAR is no longer correct. However, during the May 2019 NRC inspection, the inspectors identified that the action to update the UFSAR was still open and no revision to UFSAR, Section 9.1.4.3, was being actively pursued.

Since the change to the reactor vessel head drop analysis in the UFSAR was approved, the licensee has submitted two annual revisions of the UFSAR to the NRC, in March 2018 and on March 11, 2019. Title 10 CFR 50.71(e) requires annual updates to the UFSAR which reflect all changes up to a maximum 6 months prior to the date of filing. In this case, the licensee failed to submit a revision of UFSAR, Section 9.1.4.3, in their March 11, 2019, submittal (ADAMS Accession No. ML19092A099).

Corrective Actions: The licensee entered the issue into the corrective action program to generate a Final Safety Analysis Report change request.

Corrective Action References: Condition Report 132010

Performance Assessment:

The inspectors determined this violation was associated with a minor performance deficiency. The licensees failure to meet Procedure AP 26A-003, 10 CFR 50.59 Reviews, Revision 14, Step 6.2.1 to initiate a change to the UFSAR when a change makes the existing UFSAR information no longer correct was a performance deficiency.

Enforcement:

The ROPs significance determination process does not specifically consider the regulatory process impact in its assessment of licensee performance. Therefore, it is necessary to address this violation which impedes the NRCs ability to regulate using traditional enforcement to adequately deter non-compliance.

Severity: Because this performance deficiency had the potential to impact the NRCs ability to perform its regulatory function, it is necessary to address this violation using traditional enforcement to adequately deter non-compliance. Using the NRC Enforcement Policy, dated May 15, 2018, the violation was determined to be a Severity Level IV violation in accordance with Section 6.1.d.3, because the lack of up-to-date information in the UFSAR had not resulted in any unacceptable changes to the facility or procedures.

Violation: Title 10 CFR Part 50.71(e) requires, in part, each person licensed to operate a nuclear power reactor under the provisions of § 50.21 or § 50.22, and each applicant for a combined license under Part 52 of this chapter, shall update periodically, as provided in paragraphs (e)(3) and

(4) of this section, the Final Safety Analysis Report (FSAR) originally submitted as part of the application for the license, to assure that the information included in the report contains the latest information developed. This submittal shall contain all the changes necessary to reflect information and analyses submitted to the Commission by the applicant or licensee or prepared by the applicant or licensee pursuant to Commission requirement since the submittal of the original FSAR, or as appropriate, the last update to the FSAR under this section. The submittal shall include the effects of all changes made in the facility or procedures as described in the FSAR; all safety analyses and evaluations performed by the applicant or licensee either in support of approved license amendments or in support of conclusions that changes did not require a license amendment in accordance with § 50.59(c)(2) or, in the case of a license that references a certified design, in accordance with § 52.98(c) of this chapter; and all analyses of new safety issues performed by or on behalf of the applicant or licensee at Commission request.

Title 10 CFR Part 50.71(e)(4) requires, in part, subsequent revisions must be filed annually or 6 months after each refueling outage provided the interval between successive updates does not exceed 24 months. The revisions must reflect all changes up to a maximum of 6 months prior to the date of filing.

Contrary to the above, on March 11, 2019, the licensee made a subsequent revision to the UFSAR and failed to include all changes up to a maximum of 6 months prior to the date of filing. Specifically, on March 11, 2019, the licensee failed to update FSAR Section 9.1.4.3 to reflect the effects of a December 2017, § 50.59 safety evaluation which concluded that changes to the safety analysis for the postulated drop of the reactor vessel head during refueling activities would not require a license amendment.

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

Licensee Identified Non-Cited Violation 71152 Problem Identification and Resolution This violation of very low safety-significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: Title 10 CFR Part 50.71

(e) requires, in part, that each person licensed to operate a nuclear power reactor under the provisions of § 50.21 or § 50.22, and each applicant for a combined license under part 52 of this chapter, shall update periodically, as provided in paragraphs (e)
(3) and
(4) of this section, the Final Safety Analysis Report (FSAR) originally submitted as part of the application for the license, to assure that the information included in the report contains the latest information developed. This submittal shall contain all the changes necessary to reflect information and analyses submitted to the Commission by the applicant or licensee or prepared by the applicant or licensee pursuant to Commission requirement since the submittal of the original FSAR, or as appropriate, the last update to the FSAR under this section. The submittal shall include the effects of all changes made in the facility or procedures as described in the FSAR; all safety analyses and evaluations performed by the applicant or licensee either in support of approved license amendments or in support of conclusions that changes did not require a license amendment in accordance with § 50.59(c)(2) or, in the case of a license that references a certified design, in accordance with § 52.98(c) of this chapter; and all analyses of new safety issues performed by or on behalf of the applicant or licensee at Commission request.

Title 10 CFR Part 50.71(e)(4) requires that subsequent revisions must be filed annually or 6 months after each refueling outage provided the interval between successive updates does not exceed 24 months. The revisions must reflect all changes up to a maximum of 6 months prior to the date of filling.

Contrary to the above, between March 11, 2017 and March 11, 2019, the licensee made two subsequent revisions to the UFSAR and the changes did not reflect all changes up to a maximum of 6 months prior to the date of filing. Specifically, the licensee failed to update FSAR Section 13.2.2 to reflect the removal of requirements for six preplanned lecture series during a two-year training cycle for Nuclear Station Operators (NSOs) and two preplanned lecture series during a two-year training cycle for Treatment Systems Operators (TSOs).

Significance/Severity Level: Using the NRC Enforcement Policy, dated May 15, 2018, the violation was determined to be a Severity Level IV violation in accordance with Section 6.1.d.3, because the lack of up-to-date information in the UFSAR had not resulted in any unacceptable changes to the facility or procedures.
