SUBJECT:

WOLF CREEK GENERATING STATION - NRC INTEGRATED INSPECTION REPORT 05000482/2018004

Dear Mr. Heflin:

On December 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Wolf Creek Generating Station. On January 23, the NRC inspectors discussed the results of this inspection with Mr. C. Reasoner, Chief Nuclear Officer and Senior Vice President, and other members of your staff. The results of this inspection are documented in the enclosed report.

NRC inspectors documented two findings of very low safety significance (Green) in this report.

Both of these findings involved violations of NRC requirements. Further, inspectors documented two licensee-identified violations, which were determined to be of very low safety significance in this report. The NRC is treating these violations as non-cited violations (NCVs)

consistent with Section 2.3.2 of the Enforcement Policy.

If you contest 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 IV; the Director, Office of Enforcement; and the NRC resident inspector at the Wolf Creek Generating Station.

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 IV; and the NRC resident inspector at the Wolf Creek Generating Station. 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

Wolf Creek Generating Station began the inspection period operating at full power. On December 16, 2018, operators reduced power to approximately 98 percent following main feedwater regulating valve erratic operation. Following maintenance activities the plant was restored to approximately full power on December 21, 2018, and the plant operated at or near full power for the remainder 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.

INSPECTION RESULTS

Licensee-Identified Non-Cited Violation

71111.04 - Equipment

Alignment 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: Technical Specification 5.4.1.a, requires, in part, that procedures shall be established, implemented, and maintained covering the applicable procedures recommended by Regulatory Guide 1.33, Appendix A, Revision 2. Section 9.a of Appendix A of Regulatory Guide 1.33, Revision 2, states, in part, that maintenance that can affect the performance of safety-related equipment should be properly pre-planned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances.

The licensee established Procedure AP 30A-005, Training and Qualification, to meet the Regulatory Guide 1.33 requirement. Step 6.6.3 of Procedure AP 30A-005 requires, in part, that no person shall be considered qualified until the individuals name is reflected in the respective qualification database.

Contrary to the above, from April 8, 2018, until May 31, 2018, persons were considered qualified before the individuals names were reflected in the respective qualification database.

Specifically, during modification work in Refueling Outage 22 on the train B essential service water supply and return lines to the essential switchgear cooling units, individuals whose names were not reflected in the respective qualification database and who were not qualified via an exception, incorrectly installed pipe supports. As a result, the safety-related essential service water system was degraded from May 2018 until August 2, 2018, when bolts on the pipe support were verified to be satisfactory.

Significance/Severity Level: The inspectors determined the performance deficiency was more than minor because it adversely affected the human performance attribute of the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors assessed the significance of the finding using Exhibit 2, Mitigating Systems Screening Questions, of Inspection Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012, and determined this finding affected the design or qualification of a mitigating structure, system, and component (SSC)and that SSC maintained its operability. Therefore, the inspectors determined the finding was of very low safety significance (Green).

71111.22 - Surveillance

Testing The inspectors identified a Green, non-cited violation of 10 CFR Part 50, Criterion XI, Test Control, for the licensees failure to perform testing in accordance with written test procedures incorporating design basis requirements and acceptance limits. Specifically, design basis flow rates for the Class 1E electrical equipment air conditioning recirculation subsystem were not incorporated into testing procedures or other instructions to test the system on an ongoing basis. As a result, unacceptable degradation of recirculation system air flow rates would not have been identified.

Description:

The Class 1E electrical equipment air conditioning trains (SGK05A and SGK05B) provide a suitable environment for the Class 1E electrical equipment. These trains are operated in a continuous recirculation mode to maintain the engineered safety feature switchgear rooms at a temperature of less than or equal to 90 degrees Fahrenheit. With one Class 1E electrical equipment air conditioning train inoperable, the system design includes a recirculation subsystem that provides adequate area cooling for both trains of electrical equipment during normal and accident conditions. The recirculation subsystems installation was completed in the Spring of 2018.

Design Change Package 14269, Permanent Compensatory Modifications, Revision 6, implemented this design change that included new permanently installed fans, ductwork, dampers, and other components. The licensee also documented Calculation GK-M-016, Wolf Creek Control Building Loss of Class 1E [Air Conditioning] Gothic Room Heat Up Analysis With Installed Crosstie Fans and Louvers, Revision 2, and utilized GK-E-001, Electrical Equipment Heat Loads in [Engineered Safety Feature Switchgear, Direct Current Switchboard] and Battery Rooms, Revision 5, to confirm a single Class 1E electrical equipment air conditioning train could maintain area temperatures for both trains of electrical equipment with the implementation of mitigating actions of placing a permanently installed recirculation subsystem train in service. Additionally, the licensee created Technical Requirements Manual Surveillance Requirement 3.7.23.2 to verify each Class 1E electrical equipment air conditioning recirculation subsystem train actuates and provides recirculation air flow on an 18 month frequency.

Work Order 16-414781-000 implemented Design Change Package 14269. Work Order 16-414781-157, which was performed on April 22, 2018, performed post modification testing that verified train A air flow rates associated with subsystem fans and air conditioning units CGK05A, CGK06A, CGK07A, and SGK05A. Similarly, Work Order 16-414781-158, which was performed on May 10, 2018, performed post modification testing that verified train B air flow rates associated with subsystem fans and air conditioning units CGK05B, CGK06B, CGK07B, and SGK05B. The inspectors previously observed portions of these post-modification verification activities and noted the satisfactory but tight margins associated with some of the air flows. Post modification testing acceptance criteria and actual results are shown in the following table.

Actual Post Modification Flow (at designated locations)

CGK05A Fan 6,379 cubic feet per minute (cfm)9,208 cfm CGK06A Fan 6,379 cfm 7,052 cfm CGK07A Fan 4,706 cfm 4,752 cfm SGK05A A/C Unit

& Fan 11,168 cfm 11,179.25 cfm

On October 24, 2018, the inspectors observed the first time performance of STN GK-001A, Class 1E Recirculation System Train A Functional Test, Revision 0. The procedures purpose is to demonstrate proper operation of the train A Class 1E electrical equipment air conditioning recirculation subsystem fan and associated dampers. The acceptance criteria section of the procedure states, Perform a start of A recirculation subsystem train, verify fan running indication, verify the correct damper position indications (light indications or local) and verify air flow into the associated rooms. Step 8.1.3 performs the verification of air flow in three locationsit states, Verify air flow from the outlet of damper GK HZ-192Verify air flow from outlet of CGK06AVerify air flow from CGK05A To accomplish Step 8.1.3, test performers used their hands or tape on a stick to verify air flow. The inspectors questioned how test performers holding up their hands to feel for air flow adequately tested the system to ensure the design basis air flows were being achieved. The inspectors also noted that neither Step 8.1.3, nor any other step, procedure, nor preventive maintenance task measured air flow against specific quantitative criteria. Unless the fan failed to start or run, the test would not have been able to reasonably detect a degradation in the systems air flow characteristics, which, in some cases, have a small amount of margin. Therefore, the inspectors concluded that the procedure did not adequately test the systems air flow against the established design basis requirements and demonstrate proper operation of the system.

Corrective Actions: The licensee documented the concern in Condition Report 128121 and plans to revise the testing procedure to incorporate flow testing.

Corrective Action Reference: Condition Reports 128121 and 129579

Performance Assessment:

Performance Deficiency: The failure to perform testing in accordance with written test procedures incorporating design requirements and acceptance limits was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the procedure quality attribute of the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage).

Specifically, unacceptable degradation of recirculation system flow rates would not have been identified.

Significance: The inspectors assessed the significance of the finding using Exhibit 2, Mitigating Systems Screening Questions, of Inspection Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012, and determined this finding is not a deficiency affecting the design or qualification of a mitigating SSC, the finding does not represent a loss of system and/or function, the finding does not represent an actual loss of function of at least a single train for greater than its Technical Specification allowed outage time or two separate safety systems out-of-service, and the finding does not represent an actual loss of function of one or more non-Technical Specification trains of equipment designated as high safety-significant in accordance with the licensees maintenance rule program. Therefore, the inspectors determined the finding was of very low safety significance (Green).

Cross-Cutting Aspect: The inspectors determined that the finding has a human performance cross-cutting aspect in the area of change management in that leaders did not use a systematic process for evaluating and implementing change so that nuclear safety remains the overriding priority. Specifically, managers did not maintain a clear focus on nuclear safety when implementing the change management process during recent modification package implementation to ensure that significant unintended consequences are avoided. As a result, design required performance criteria for recirculation system testing were not incorporated into applicable testing procedures.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion XI, Test Control, requires, in part, that required testing is identified and performed in accordance with written test procedures that incorporate the requirements and acceptance limits contained in applicable design documents.

Contrary to the above, from May 2018 until January 23, 2018, all required testing was not identified and performed in accordance with written test procedures that incorporate the requirements and acceptance limits contained in applicable design documents. Specifically, the licensee failed to identify in testing procedures design basis required performance criteria for Class 1E electrical equipment air conditioning recirculation subsystem air flows in specific locations. As a result, unacceptable degradation of Class 1E electrical equipment air conditioning recirculation subsystem air flows rates would not have been identified.

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

Green NCV 05000482/2018004-02 Closed

[H.9] - Training

71152 - Problem

Identification and Resolution The inspectors identified a Green, non-cited violation of 10 CFR Part 50, Criterion V, Instructions, Procedures, and Drawings, which requires, in part, that activities affecting quality shall be accomplished in accordance with instructions, procedures, or drawings.

Specifically, the inspectors identified a programmatic failure to adequately implement control and separation of stainless steel tools in accordance with Procedure, AI 12-003, Control and Separation of Tools to be Used on Stainless Steel, Revision 1, which required, in part, that tools/equipment designated for stainless steel use only shall be identified, stored, and issued in accordance with this procedure.

Description:

As of result of the inspectors questions about control and separation of stainless steel tools and equipment, the licensee conducted an audit of the stainless steel tool control program. The following deficiencies were identified and documented in Condition Report 125600 on August 6, 2018:

• No stainless steel program owner was established in accordance with Procedure AI 12-003.

• Corrective actions implemented in 2012 and documented in Condition Report 36444 required pre-outage training for contractors/supplemental personnel, which has not occurred since 2016.

• Training to onsite maintenance personnel was discontinued after initial just-in-time training in 2012.

The inspectors also performed tours of the tool rooms and interviewed maintenance personnel. The inspectors identified that licensee personnel were justifying the use of uncontrolled tools in the tool rooms for use in stainless steel applications. Additionally, the inspectors identified multiple tool storage areas in the plant where tools were stored in unlocked and uncontrolled drawers marked as stainless steel or S.S., or where tools were stored in unlocked and uncontrolled drawers and possibly being marked for stainless steel use. The licensee initiated Condition Reports 128104, 128116, 128124, and 128330 to address the inspectors questions and observations.

Procedure AI 12-003, Section 6.1, Tool Rooms, Step 6.1.1, states that tools and equipment designated for stainless steel use only, shall be identified, stored, and issued such that a tool is clearly marked identifying the tool for stainless steel use only. Step 6.1.2 states, Store tools/equipment designated for stainless steel use only in designated storage location (drawer/s) marked clearly as Stainless Steel Use Only. Step 6.1.2.1, states, Storage locations shall be locked when not in use.

The inspectors reviewed previous condition reports written since April 2018 and determined that the licensee performed additional tool control program spot checks in which the licensees Quality Assurance department identified the following additional deficiencies:

• The licensee identified stainless steel tools in the pipe fabrication shop that were in an unlocked stainless steel storage container, improperly marked stainless steel tools, rusty stainless steel tools indicating possible contamination with carbon steel, and stainless steel tools not segregated from general use tools.

• Cadmium plated washers and bolts were stored in the stainless steel only drawer in the hot tool room.

• Procedure AI 12-003 tasks were performed 11 times by personnel who had not received the required training prior to performing these tasks.

The inspectors determined that station personnel were not adequately trained on the tool separation requirements as required by the procedure. When the licensees quality assurance department identified that personnel performing tool control inventory and separation activities were not receiving initial or recurring training on the tool separation requirements, the licensee decided to remove the training from the training system and rely on personnel following the written procedure. However, based on the answers to the inspectors questions about tool separation requirements, it was apparent that individuals performing these tasks were neither adequately aware of the requirements nor adequately trained on the requirements. The inspectors did not identify any contamination of stainless steel structures, systems, or components in the plant; however, because of the multiple deficiencies identified since April of 2018, the inspectors concluded that a programmatic failure of the licensees stainless steel tool control program to prevent or eliminate cross contamination of stainless steel tools and equipment had occurred.

Corrective Actions: The licensee has implemented new training requirements for personnel involved with the control and separation of stainless steel tools.

Corrective Action References: Condition Reports 125600, 128104, 128116, 128124, 128330, and 129578

Performance Assessment:

Performance Deficiency: The failure to follow the programmatic requirements of Procedure AI 12-003, Control and Separation of Tools to be used on Stainless Steel, was a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the human performance attribute of the Initiating Events Cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, if left uncorrected, the failure to adequately control and separate tools would have the potential to lead to a more significant safety concern such as corrosion of safety system piping or an initiating event.

Significance: The inspectors assessed the significance of the finding using Exhibit 1, Initiating Events Screening Questions, of Inspection Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012, and determined this finding did not result in exceeding the reactor coolant system leak rate for a small loss of coolant accident and could not have likely affected other systems used to mitigate a loss of coolant accident resulting in a total loss of function. Therefore, the inspectors determined the finding was of very low safety significance (Green).

Cross-Cutting Aspect: The inspectors determined that the finding has a human performance cross-cutting aspect in the area of training in that the organization did not provide training and ensure knowledge transfer to maintain a knowledgeable, technically competent workforce and instill nuclear safety values. Specifically, individuals, including supplemental workers, were not adequately trained on the stainless steel tool control program to ensure technical competency and an understanding of standards and work requirements. As a result, stainless steel tools were not properly controlled and could have contaminated stainless steel SSCs in the plant.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Licensee Procedure AI 12-003, Control and Separation of Tools to be used on Stainless Steel, an Appendix B quality related procedure, provides instructions for controlling and maintaining separation of tools to be used on stainless steel. Procedure AI 12-003, Steps 6.1.1, 6.1.2, and 6.1.2.1, required, in part, that tools and equipment designated for stainless steel use only shall be identified, appropriately marked for stainless steel use only, stored in designated storage locations, and that storage locations are locked when not in use.

Contrary to the above, from April 2018 through November 2018, tools and equipment designated for stainless steel use only were not identified, appropriately marked for stainless steel use only, stored in designated storage locations, and storage locations were not locked when not in use. Specifically, the licensee failed to implement the programmatic requirements of AI 12-003, Control and Separation of Tools to be used on stainless Steel, Revision 1, resulting in the collocation of stainless and non-stainless steel tools which could have led to degradation of stainless steel SSCs in the plant.

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

The inspectors reviewed the licensees progress in addressing the cross-cutting theme in the SCWE area, as discussed in the 2017 Annual Assessment Letter for Wolf Creek Generating Station (Inspection Report 05000482/2017006, Agencywide Documents Access and Management System (ADAMS) Accession No. ML18052A345). This semi-annual review effort included consideration of previous NRC reviews of the licensees progress in addressing the SCWE theme, recent actions that Wolf Creek has completed and planned to address the cross-cutting theme in the SCWE area, and consideration of recent enforcement actions taken by the NRC.

• Background

Inspection Report 05000482/2017004 (ADAMS Accession No. ML18043A114)contains a Green NCV of 10 CFR Part 50, Appendix B, Criterion V, for failure to initiate a condition report to evaluate the operability of control rod drive mechanisms that had boric acid residue on them. The inspectors determined that the finding had a SCWE cross-cutting aspect in the area of SCWE policy, in that an individual did not feel free to raise nuclear safety concerns without fear of retribution, with confidence that his/her concerns will be addressed. Specifically, an individual was reluctant to write a condition report to document boric acid residue on control rod drive mechanisms because he believed leaders were not concerned, and he did not want to diminish the relationship he had with the leaders.

Two additional problem identification and resolution inspection inputs documented a biennial team inspection (Inspection Report 0500482/2016009, ADAMS Accession No. ML6222A733) and a focused annual sample (Inspection Report 05000482/2017003, ADAMS Accession No. ML7311B223), which identified that some personnel within the security and maintenance departments would be reluctant to raise important issues (including nuclear safety issues) without fear of retaliation.

Considering all of this information, the NRC determined that a cross-cutting theme existed in the area of SCWE at Wolf Creek. This theme was documented in the 2017 Annual Assessment Letter for Wolf Creek Generating Station (Inspection Report 05000482/2017006, ADAMS Accession No. ML18052A345) on March 1, 2018.

• Previous Inspection Efforts

The NRCs review of the licensees progress in addressing the SCWE theme was previously accomplished within the scope of the biennial problem identification and resolution inspection, which was completed on June 28, 2018. NRC Inspection Report 05000482/2018007 (ADAMS Accession No. ML18218A265), dated August 8, 2018, discusses the results of this inspection, which concluded that actions taken to address the work environment challenges in the maintenance support group had not yet been effective.

The problem identification and resolution inspection team noted that Condition Report 119954 and its associated apparent cause evaluation were performed by the licensee to evaluate circumstances that led to the SCWE cross-cutting theme following receipt of the NRCs 2017 Annual Assessment letter. The problem identification and resolution inspection team also noted that Condition Report 124660 documented the inspectors observation that the licensees effectiveness measures may validate that the planned actions have been accomplished but not whether they had been successful at correcting the deficiency they were intended to correct.

• Recent Issues

In a letter dated July 12, 2018 (ADAMS Accession No. ML18136A501), the NRC notified the licensee of an apparent violation of 10 CFR 50.7, Employee protection, which the NRC was considering for escalated enforcement action in accordance with the NRC Enforcement Policy. The licensee initiated Condition Report 125270, which was downgraded from a significant condition adverse to quality and a root cause assessment to a condition adverse to quality and a find, fix, and action needed designation with a gap assignment (Action 125270-03-01).

On September 10, 2018, the NRC held a predecisional enforcement conference (PEC)at the NRC Headquarters office in Rockville, Maryland, with members of the licensee staff to discuss the apparent violation, its significance, the root cause(s), and any corrective actions. The licensee agreed to subsequently provide its corrective actions in writing. In a letter dated September 17, 2018 (ADAMS Accession No. ML18324A514), the licensee provided its corrective actions to the NRC.

In a letter dated December 17, 2018 (ADAMS Accession No. ML18333A043), the NRC issued EA-18-037, Wolf Creek Nuclear Operating Corporation - Notice of Violation and Proposed Imposition of Civil Penalty - $232,000 (Office of Investigations Report No. 4-2017-020), which determined that a contract employee engaged in protected activity when the employee initiated a condition report for an incident during the 2016 refueling outage, communicated related concerns directly to licensee management, and raised retaliation and SCWE concerns directly to licensee management.

Subsequently, the former contractor was placed on paid administrative leave. The letter, dated December 17, 2018, also concluded that the licensees investigation did not focus on the concerns raised by the contract employee. Instead, the licensees investigation focused primarily on the contract employees behavior and did not review the employees claim of retaliation. The letter also states that the NRC considers violations of 10 CFR 50.7 significant because of the potential that individuals might not raise safety issues for fear of retaliation. Based on the level of management involved in the adverse action, this violation was categorized in accordance with the NRC Enforcement Policy at Severity Level II.

The licensee initiated Condition Report 128909 associated with the Severity Level II violation. As of January 8, 2019, the issue was considered by the licensee to be a significant condition adverse to quality requiring a root cause analysis, which had not yet been completed.

• Completed Actions

As previously noted, Condition Report 119954 and its associated apparent cause evaluation were performed by the licensee to evaluate circumstances that led to the SCWE cross-cutting theme following receipt of the NRCs 2017 Annual Assessment letter. The inspectors noted that the apparent cause evaluation associated with Condition Report 119954 concluded that there were no significant SCWE issues identified, but it noted that some of the questionnaires indicated potential work environment issues. The evaluation went on to state, While these were not SCWE issues, the behaviors associated with the identified work environment issues have many of the same behaviors that could cause SCWE concerns if left unchecked.

Actions to address these conclusions included Remedial Action 119954-03-05, Develop Leadership Training, which included a 1-day continuing leadership development presentation and a 1-day dynamic learning activity that included three activities to emphasize appropriate/inappropriate behaviors related to job performance appraisals, gossip in the workplace, and employee reluctance to use internal avenues for reporting concerns. Preventive Action 119954-03-06 required oral boards for leaders following completion of the dynamic learning activity.

Additional actions to address these conclusions included Remedial Action 119954-03-01, Revise AI 36-001, which revised Procedure AI 36-001, Nuclear Safety Culture Panel, to include changes in panel membership, quorum requirements, and scoring guidance. The purpose of AI 36-001 is described as, An ongoing holistic, objective, transparent and safety-focused process, which uses the information available, to provide early indication of potential problems, linked to culture. Revision 6 of AI 36-001, issued September 19, 2018, implemented Action 119954-03-01.

Other actions to address the conclusions included training corrective action program screening review team members on applying nuclear safety culture traits and attributes to condition reports; developing a charter for the Senior Leadership Team meeting, which includes work environment and safety culture topics on a set periodicity; revising site meeting schedules to ensure time for supervisors to meet with personnel and perform observations; and implementing a requirement for new leaders to be assigned a mentor for a minimum period of six months.

As previously described, following the PEC on September 10, 2018, the licensee agreed to subsequently provide its corrective actions in writing. In a letter dated September 17, 2018 (ADAMS Accession No. ML18324A514), the licensee provided its corrective actions to the NRC. In a letter dated January 15, 2019 (ADAMS Accession No. ML19031C779), the licensee notified the NRC that the corrective actions documented in the September 17, 2018, letter to the NRC and in Condition Report 125270 have been completed. The inspectors validated a sampling of these actions were completed.

Specifically, on September 17, 2018, the licensee initiated Corrective Action 125270-03-03, Provide training for executive leaders on SCWE consistent with the training provide[d] in the Chilling Effects Letter. This action was completed on December 6, 2018. Also on September 17, 2018, the licensee initiated Corrective Actions 125270-03-04, Revise the [Personnel Action Review Board (PARB)]

procedure with the intent of improving scope, and 125270-05, Revise the PARB process to direct general council awareness. Step 4.12, Personnel Action, of Procedure AI 13C-003, Personnel Action Review Board (PARB), was revised to include the placing of an individual on administrative leave as an event that would trigger a PARB. Additionally, Step 6.5, PARB Review Process, was revised to require a PARB to be completed within two days of an individual being placed on leave. Step 5.2 of the procedure was also revised to ensure Vice President Engineering and Legal Counsel are informed prior to taking any personnel action.

Subsequently, the inspectors also observed other SCWE-related licensee actions, which included aspects of the licensees November SCWE communications and December 2018 SCWE Blitz. These activities included a site-wide stand down that communicated to employees on SCWE topics described in the new primer, SCWE:

Our Role in Nuclear Safety; all employee meetings discussing SCWE topics; and additional communications on SCWE topics.

• Planned Actions

Corrective Action 125270-03-06, Develop comprehensive SCWE strategy, was also initiated on September 17, 2018. An overarching SCWE strategy was initiated and then completed on December 14, 2018, which included discussions of policy, responsibilities and behaviors, training, a communication plan, ongoing monitoring, and oversight. The SCWE strategy also described specific planned actions, which included:

o The SCWE policy is maintained within the Corporate Policy Manual and will be reviewed and updated for sufficiency;

o The Employee Handbook, Principles of Integrity and the Wolf Creek way will be reviewed;

o Standard [supplemental employee] contract language will be reviewed and updated for sufficiency; o [SCWE] responsibility and behaviors will be emphasized through organizational learning and employee development;

o Training will be required at each level of the organization (executives, leadership, employees and supplemental personnel), on an annual basis;

o Leadership of centralized functions between Wolf Creek and its majority owner company, Evergy, will also be included in the SCWE training;

o Specific training will be embedded intonew hire orientation, supplemental personnel onboarding, andleadership development program;

o A long-term SCWE Communication Plan will be established, and will be implemented by Corporate Communications and leadership;

o Additional [SCWE] blitzes will occur in 2019 and beyond;

o Wolf Creek will use ongoing monitoring to continually assess progress towards achieving and maintaining a strong and healthy SCWE; and

o Information gathered duringongoing monitoring process will be considered for training enhancements, coaching opportunities, communication changes, organizational changes, and survey topics.

The SCWE strategy and related actions are expected to be tracked by non-condition adverse to quality Condition Report 128709. This condition report was open as of January 8, 2019, and no specific actions, as discussed in the SCWE strategy document, had yet been identified for tracking.

The SCWE strategy also concluded that implementation of the SCWE strategy and action plans associated with initiative #1 of the stations 2019-2021 business plan will lead to a healthy SCWE. The Drive to Excellence business plan actions are expected to be tracked by non-condition adverse to quality Condition Report 128711.

This condition report was open as of January 8, 2019, and no specific actions had yet been identified.

• Assessment

In response to inspector observations documented in NRC Inspection Report 05000482/2018007, the licensee created Remedial Action 124660-01-01 on July 25, 2018, to conduct surveys with target groups and compare results to baseline survey results; the success criteria was established as survey results indicating improvement in the work environment of the target groups. The inspectors noted Procedure AP 28A-100, Corrective Action Program, Revision 24, defines remedial actions as, Corrective actions necessary to restore compliance of the

[condition adverse to quality]. The inspectors noted that AI 28A-100, Condition Report Resolution, describes an effectiveness follow-up plan as, A plan that contains established criteria that defines how effectiveness of corrective actions for adverse conditions will be determined. The procedure also states, Establish quantitative and qualitative acceptance criteria for monitoring or evaluating the attributes. Specify at what depths recurrence will be tolerated and determine if non-consequential precursor events are acceptable. The inspectors identified that Remedial Action 124660-01-01 did not include specific quantitative acceptance criteria language or what level of recurrence would be tolerated. The inspectors communicated these observations to the licensee.

The inspectors noted that Procedure AP 28A-100, Corrective Action Program, Revision 24, defines non-conditions adverse to quality as issues that may warrant management resolution that have no regulatory basis for inclusion in the corrective action program. The procedure states, These conditions are not part of the

[corrective action program]. The inspectors also noted that Procedure AI 28A-100, Condition Report Resolution, Revision 15, Step 6.1.3, states, A [condition report]

can be closed to another [condition report] of equal or higher severity type and/or evaluation level (i.e., a [basic cause] evaluation can be closed to a [root cause evaluation], but a [root cause evaluation] cannot be closed to a [basic cause]

evaluation. Additionally, the procedure states, The [condition report] remaining open will specifically identify the closed [condition reports] condition and how it has been addressed prior to the closure justification of the final [condition report]. The inspectors identified that Condition Report 128709, a non-condition adverse to quality, was being utilized to track completion of an action first identified in Condition Report 125270, a condition adverse to quality. The inspectors communicated these insights to the licensee, and the licensee subsequently initiated Condition Report 129494. The inspectors also identified that Condition Report 128711, a non-condition adverse to quality, was being utilized to track completion of an action coming out of the SCWE strategy, which was first identified in Condition Report 125270, a condition adverse to quality. The inspectors communicated these insights to the licensee, and the licensee also subsequently initiated Condition Report 129494.

With respect to overall progress in addressing the cross-cutting theme in the SCWE area, the licensee had completed or planned a number of actions to address SCWE concerns as of January 8, 2019. The inspectors determined that there are important planned actions that still need to be completed, there are important outstanding actions still to be articulated, and the adequate implementation of these actions is necessary to adequately address SCWE at Wolf Creek. Specifically, specific actions described in the SCWE strategy and Condition Report 128709 need to be appropriately articulated and tracked within the corrective action program to ensure effective implementation. Completion of and effective implementation of the 2019-2021 business plan, its associated described actions, and Condition Report 128711 is also an important part of the licensees planned corrective actions.

The licensees conclusions and actions associated with the Severity Level II issue and Condition Report 128909 are required to prevent recurrence of the significant condition adverse to quality. Finally, effective actions to monitor and measure working level employees willingness to raise concerns are necessary to ensure SCWE issues are being resolved and individuals feel free to raise safety concerns. Future NRC oversight activities to determine the licensees progress in addressing the cross-cutting theme in the SCWE area should include a detailed review of all of these actions.

Mitigating System Performance Indicators

The inspectors also considered whether there was an emerging trend associated with inaccurate accounting and reporting of mitigating system performance indicator data.

Considering that each mitigating system performance indicator is only reviewed by inspectors on an annual basis the inspectors considered issues identified during 2016, 2017, and 2018 mitigating system performance indicator inspections. Some of these issues included:

• In response to a request from the inspectors, the licensee identified an error in the October 2015 unavailability data for train A safety injection pump. On September 13, 2016, Condition Report 107112 documented this issue. In response to a request from the inspectors, the licensee identified an error in the July 2015 unavailability data for train A auxiliary feedwater. On October 17, 2016, Condition Report 108475 documented this issue.

• During review of March 2017 unreliability data for the train B component cooling water pump licensee personnel identified test run hours that were inappropriately counted.

On June 27, 2017, Condition Report 114069 documented this issue.

• On October 4, 2017, Condition Report 116357 documented NRC identified issues associated with safety injection, residual heat removal, essential service water, and component cooling water system unavailability and demand data.

• On October 23, 2017, Condition Report 116832 documented three unavailability and demand data entry errors associated with the residual heat removal and auxiliary feedwater systems.

• On November 2, 2017, Condition Report 117159 documented licensee identified issues associated with component cooling water test demand data.

• On December 19, 2017, Condition Report 118203 documented that Quick Hit Self-Assessment QH-2017-1577 had noted the conditions identified by Condition Reports 107112, 108475, and 114069, as previously described.

• On January 4, 2018, Condition Report 118500 documented November and December 2016 auxiliary feedwater reliability data errors identified by the inspectors.

• On May 30, 2018, Condition Report 123890 documented a licensee identified issue associated with train B emergency diesel generator unreliability data.

• On June 28, 2018, Quick Hit Self-Assessment QH-2018-1693, Nuclear Regulatory Commission (NRC) Reactor Oversight Program (ROP) Performance Indicator Program, was completed. The licensee assessment identified three errors in mitigating system performance indicator reliability data. The errors were in the March 2015 demand data for the residual heat removal supply to safety injection pump B isolation valve, the June 2015 demand data for train A safety injection pump, and the November 2015 train B charging pump run-time data.

The inspectors also identified during 2018 inspections numerous mitigating system performance indicator errors requiring updates to consolidated data entries. Some of these issues included:

• The inspectors identified a January 2018 start of the train A centrifugal charging pump that was recorded as a non-test demand and should have been recorded as a test demand; this necessitated revisions to the demand and run-time data.

• The inspectors identified a March 2018 train A safety injection pump start that was inappropriately recorded as a non-test demand for the opposite train; this necessitated revisions to the demand and run-time data for both trains of safety injection.

• The inspectors identified that the number of non-test demands for train A essential service water pumps included an extra non-test demand in April 2018; this necessitated revisions to the demand data for the train.

• The inspectors identified train A emergency diesel run time in May 2018 that was not reported as test run time; this necessitated revisions to the reliability data.

• The inspectors questioned the unavailability associated with train A component cooling water and train A essential service water. As a result of the inspectors questions the licensee determined that the mitigating system performance indicator data for both trains required revision.

The licensee initiated Condition Reports 127496, 127526, and 127634, in response to the inspectors concerns. Updated unreliability and unavailability data entries were made by the licensee, and no cases were identified where data entry updates caused a performance indicator threshold to be exceeded.

Remedial and preventive actions to correct the data and provide training to engineers responsible for data collection and reporting, respectively, were created associated with Condition Report 127634.

The inspectors determined that this collection of errors was indicative of an adverse trend.

The inspectors shared this observation with the licensee and the licensee expressed agreement with the trend and documented it in Condition Report 129198 on January 8, 2019.

Licensee-Identified Non-Cited Violation 71153 - Follow-up of Events and Notices of Enforcement Discretion 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: Technical Specification 3.6.3, Containment Isolation Valves, requires, in part, that with one or more penetration flow paths with one or more containment purge valves that is not within leakage limits, the affected penetration flow path must be isolated by use of at least one closed and de-activated automatic valve, closed manual valve, or blind flange within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Contrary to the above, from May 15, 2018, until August 8, 2018, with one or more penetration flow paths with one or more containment purge valves not within leakage limits, the affected penetration flow path was not isolated by use of at least one closed and de-activated automatic valve, closed manual valve, or blind flange within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Specifically, containment shutdown purge isolation valve GTHZ0006 was found to have leakage that was not within leakage limits, and a non-safety related and non-seismically qualified blind flange was utilized to isolate the affected penetration flow path.

Significance/Severity Level: The inspectors determined the performance deficiency was more than minor because it adversely affected the configuration control attribute of the Barrier Integrity Cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. Specifically, the operability of a containment penetration flow path was adversely impacted. The inspectors assessed the significance of the finding using Exhibit 3, Barrier Integrity Screening Questions, of Inspection Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012, and determined this finding does not represent an actual open pathway in the physical integrity of reactor containment, containment isolation system, and heat removal components, and the finding does not involve an actual reduction in function of hydrogen igniters in the reactor containment. Therefore, the inspectors determined the finding was of very low safety significance (Green).

Corrective Action References: Condition Reports 123255, 123360, 125673, and 129580

Observation 71153 - Follow-up of Events and Notices of Enforcement Discretion On September 7, 2017, the licensee identified that there was no retrievable analysis proving that a single tornado driven design basis missile is not capable of affecting more than two atmospheric relief valves. This vulnerability was identified as part of the licensees review of operating experience from the Callaway Plant regarding potential nonconforming conditions related to tornado generated missile effects on main steam safety valves and atmospheric relief valves. These tornado missile vulnerabilities have existed since original plant construction. The licensee invoked Enforcement Guidance Memorandum 15-002, Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance, Revision 1, implemented initial compensatory measures, and returned the SSCs to an operable-degraded/non-conforming status. NRC Inspection Report 05000482/2017003 (ADAMS Accession No. ML17311B223) dated November 7, 2017, documented that the NRC exercised enforcement discretion by not issuing an enforcement action and allowing continued reactor operation.

The licensee initiated Correction Action 115590-06-06, Exit Enforcement [Discretion] and Retract LER. Specifically, this corrective action would retract Licensee Event Report (LER) 2017-003-00, [Atmospheric Relief Valve] and [Main Steam Safety Valve]

Tornado Missile Vulnerabilities Result in Unanalyzed Condition.

At the end of the inspection period, the inspectors had reviewed LER 2017-003-00 and noted the remedial corrective action to retract the aforementioned licensee event report. The inspectors were unable to close LER 2017-003-00 with this corrective action pending. The inspectors will revisit possible closure of LER 2017-003-00 when the licensees corrective actions are completed.

EXIT MEETINGS AND DEBRIEFS

On January 23, 2019, the inspector presented the quarterly resident inspector inspection results to Mr. C. Reasoner, Chief Nuclear Officer and Senior Vice President, and other members of the licensee staff. The inspectors verified no proprietary information was retained or documented in this report.
