SUBJECT:

WOLF CREEK GENERATING STATION - NRC INTEGRATED INSPECTION REPORT 05000482/2018002 AND ASSESSMENT FOLLOW-UP LETTER

Dear Mr. Heflin:

On June 30, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Wolf Creek Generating Station. On July 17, 2018, 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. Additionally, NRC inspectors documented one Severity Level IV violation with no associated finding. The NRC is treating these violations as non-cited violations (NCV) 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.

In the 2017 Annual Assessment Letter for Wolf Creek Generating Station (Report 05000482/2017006, Agencywide Documents Access and Management System (ADAMS) ML18052A345), the NRC identified a cross-cutting theme in the safety conscious work environment (SCWE) area. On August 8, 2018, the NRC documented an assessment of the licensees progress in addressing the SCWE theme in NRC Inspection Report 05000482/2018007 (ADAMS ML18218A265). The inspectors determined that while the licensee had taken some corrective actions to address the work environment challenges on site, these actions had not yet been effective to improve the SCWE in the maintenance support group.

Based on this conclusion and the previously documented finding with a cross-cutting aspect related to the inconsistent implementation of SCWE policy (S.1), as discussed in NRC Inspection Report 05000482/2017004 (ADAMS ML18043A114), the NRC determined that a theme in the SCWE area continues to exist. The NRC will continue to monitor your staffs progress in implementing corrective actions for this theme.

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.

Sincerely,

/RA/

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an Integrated Inspection at Wolf Creek Generating Station in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information. NRC-identified and self-revealed findings, violations, and additional items are summarized in the table below.

List of Findings and Violations Announcement of an NRC Inspectors Presence by Station Personnel Cornerstone Significance Cross-cutting Report Aspect Section Not Severity Level IV Not 71111.20 -

Applicable NCV Applicable Refueling 05000482/2018002-01 and Other Closed Outage Activities The inspectors identified a Severity Level IV non-cited violation (NCV) of 10 CFR 50.70(b)(4),

Inspections, associated with the licensees failure to ensure the arrival and presence of NRC Inspectors, who had been properly authorized facility access as described in 10 CFR 50.70(b)(3), were not announced or otherwise communicated by its employees or contractors to other persons at the facility without a specific request by the NRC inspector.

Specifically, a contract radiation protection technician entered the spent fuel pool building where the resident inspector was present and observing core offload activities, and the technician informed members of a work crew of the whereabouts of an NRC radiation protection inspection team without being requested to do so; this impacts the NRCs ability to regulate and perform unannounced inspections.

Failure to Maintain Adequate Pressurization of the Control Room Envelope Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green [H.3] - 71152 -

Systems NCV 05000482/2018002-02 Human Problem Closed Performance, Identification Change and Management Resolution A self-revealed Green NCV of 10 CFR Part 50, Criterion III, Design Control, was identified when the licensee failed to adequately recognize that the cable spreading room floor was a control building ventilation isolation boundary. Specifically, the licensee cut openings in the floor/ceiling between the 2,032 foot and 2,016 foot elevations of the control building and the impact on the control room envelopes ability to pressurize was not recognized. This was a primary contributor to the train B control room emergency ventilation system being unable to maintain the appropriate pressure in the control room envelope.

Failure to Adequately Implement Instrumentation and Controls Surveillance Procedures Cornerstone Significance Cross-cutting Report Aspect Section Initiating Green [H.2] - Human 71152 -

Events NCV 05000482/2018002-03 Performance, Problem Closed Field Presence Identification and Resolution A self-revealed Green NCV of 10 CFR Part 50, Criterion V, Instructions, Procedures, and Drawings, was identified when the licensee failed to adequately implement surveillance procedures that affected safety-related equipment and plant stability. Specifically, the licensee failed to adequately implement testing and calibration procedures for pressurizer level instrumentation. This resulted in two letdown isolation signals, securing of pressurizer heaters, and a pressurizer level transient on March 29, 2018.

PLANT STATUS

Wolf Creek Generating Station began the inspection period shutdown for Refueling Outage 22.

The reactor was restarted on May 17, 2018, and power ascension was commenced. The unit was returned to approximately rated thermal power on May 21, 2018, and remained at or near rated thermal power for the remainder of 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 2515, Light-Water Reactor Inspection Program

- Operations Phase. The inspectors performed plant status activities described in Inspection Manual Chapter 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.

The inspector reviewed whether the personnel performing the inspection were certified examiners to their respective nondestructive examination method.

On May 10, 2018, the licensee was granted verbal approval for performing an alternative volumetric examination and leak path assessment in lieu of the visual examination requirements of Note 1 of Table 1, American Society of Mechanical Engineers Code Case N-729-4. Although not indicative of possible nozzle leakage, the licensee was not able to perform the required visual examination of penetration number one due to a hard substance obstructing the annulus. At the time of the inspection, the licensee had satisfactorily completed the ultrasonic inspection and leak path assessment. The licensee had also cleaned the annulus of penetration number one.

(3) Boric Acid Corrosion Control Inspection Activities The Inspector evaluated the licensees boric acid control program performance.

(4) Steam Generator (SG) Tube Inspection Activities The inspector reviewed the SG tube eddy current examination scope and expansion criteria to determine whether these criteria met technical specification requirements, Electric Power Research Institute (EPRI) guidelines, and commitments made to the NRC. The inspector also reviewed whether the eddy current inspection scope included areas of degradations that were known to represent potential eddy current test challenges such as the top of tube sheet, tube support plates, and U-bends. The inspector confirmed that no repairs were required at the time of the inspection and that the licensees inspection scope was appropriate.

(5) Identification and Resolution of Problems (71111.08-02.05)

The inspector reviewed 14 condition reports, which dealt with inservice inspection activities, and found the corrective actions for inservice inspection issues were appropriate.

INSPECTION RESULTS

Announcement of an NRC Inspectors Presence by Station Personnel Cornerstone Severity Cross-cutting Aspect Report Section Not Applicable Severity Level IV Not Applicable

71111.20 - Refueling

NCV and Other Outage 05000482/2018002-01 Activities Closed The inspectors identified a Severity Level IV NCV of 10 CFR 50.70(b)(4), Inspections, associated with the licensees failure to ensure the arrival and presence of NRC Inspectors, who had been properly authorized facility access as described in 10 CFR 50.70(b)(3), were not announced or otherwise communicated by its employees or contractors to other persons at the facility without a specific request by the NRC inspector. Specifically, a contract radiation protection technician entered the spent fuel pool building where the resident inspector was present and observing core offload activities, and the technician informed members of a work crew of the whereabouts of an NRC radiation protection inspection team without being requested to do so; this impacted the NRCs ability to regulate and perform unannounced inspections.

Description:

On April 10, 2018, the resident inspector was in the spent fuel pool building observing fuel movement activities in support of core off-load for Refueling Outage 22. NRC radiation protection inspectors were also onsite conducting inspection activities. At approximately 11:00 a.m., the resident inspector observed a BHI contractor enter the spent fuel pool building and announce to members of a work crew that NRC inspectors had entered the radiologically controlled area (containment) and to be mindful and careful.

The resident inspector spoke with the visiting NRC radiation protection inspectors later that afternoon and confirmed they had entered containment at approximately 10:30 a.m. on April 10, 2018, and had not requested that their presence be announced. The resident inspector noted that his location in the spent fuel pool building, where the announcement of NRC inspectors had occurred, was in close proximity to where the other NRC inspectors were entering containment.

Corrective Actions: On April 25, 2018, the licensee entered this issue into the corrective action program. Additional corrective actions included the performance of a stand down with all BHI employees to inform them that conduct that alerts workers to the presence of the NRC, or any oversight group, is prohibited; the licensee also published an article in a site newsletter explaining the requirements of 10 CFR 50.70. The article informed site personnel that a violation had occurred and described site management expectations regarding appropriate conduct.

Corrective Action References: Condition Reports 122359 and 122375.

Performance Assessment:

The inspectors determined this violation was associated with a minor performance deficiency.

Enforcement:

The Reactor Oversight Processs 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: The finding was evaluated in accordance with the NRC's Enforcement Policy. The finding was reviewed by NRC management and because the violation was of very low safety significance, was not repetitive or willful, and was entered into the corrective action program, this violation is being treated as a Severity Level IV NCV, consistent with the NRC Enforcement Policy.

Violation: Title 10 CFR 50.70(b)(4), Inspections, requires, in part, that the licensee shall ensure that the arrival and presence of an NRC inspector, who has been properly authorized facility access as described in 10 CFR 50.70(b)(3), is not announced or otherwise communicated by its employees or contractors to other persons at the facility unless specifically requested by the NRC inspector.

Contrary to the above, on April 10, 2018, the licensee failed to ensure that the arrival and presence of NRC inspectors, who had been properly authorized facility access as described in 10 CFR 50.70(b)(3), were not announced or otherwise communicated by its employees or contractors to other persons at the facility unless specifically requested by the NRC inspectors. Specifically, a radiation protection technician entered the spent fuel pool building and informed members of a work crew of the whereabouts of NRC radiation protection inspectors without being requested to do so.

Enforcement Action: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

Observation

71152 - Problem

Identification and Resolution 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 (Report 05000482/2017006, ADAMS ML18052A345). The NRCs review of the licensees progress in addressing the SCWE theme was 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 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 inspectors also considered whether there was an emerging trend associated with impacting the regulatory process. The inspectors noted NCV 05000482/2018002-01, as documented in this report, which involved announcement of an NRC inspectors presence by station personnel. The inspectors also noted that the announcement of an inspectors presence was not an isolated event. Specifically, the presence of an NRC inspector was announced by a Wolf Creek employee to a state official during a drill on February 27, 2018.

However, the inspectors determined that no violation occurred in this case because the announcement, which was not requested by the inspector, was not made to licensee personnel and was thereby outside the NRCs regulatory authority. These issues and other reportability questions being evaluated by ongoing inspections were considered, and no emerging trend has been identified at this time.

The inspectors noted that four NCVs that occurred within an approximate 1 year time period relate to the licensees understanding of the design basis and design basis implementing documents. Specifically:

• NCV 05000482/2018002-02, Failure to Maintain Adequate Pressurization of the Control Room Envelope, involved a failure to ensure an implementing documentthe boundary matrixidentified all boundary functions; this led to a failure to control a boundary and was a primary contributor to the failure to pressurize the control room envelope.

• NCV 05000482/2018001-01, Inadequate Functionality Assessment Associated with the Emergency Excess Letdown Flowpath, involved discrepancies between the Technical Specification Bases, procedures, and the updated safety analysis report; these discrepancies contributed to an inadequate functionality assessment.

• NCV 05000482/2017003-02, Failure to Ensure the Design Basis was Adequately Represented in the Technical Specification Bases, involved discrepancies between the auxiliary feedwater Technical Specification Bases and the updated safety analysis report; as a result, inoperability of an auxiliary feedwater train was not recognized.

• NCV 05000482/2017002-02, Failure to Declare Train A Component Cooling Water Inoperable, related to the Technical Specification Bases not specifically identifying specific valves importance to the safety-related design functions as outlined in the updated safety analysis report; as a result, inoperability of safety-related equipment was not recognized.

In each of these cases the inspectors observed that the updated safety analysis report was not consistently being referenced when questions about the adequacy or completeness of the Technical Specification Bases were identified. The inspectors also observed that each of these NCVs represented some organizational knowledge gap concerning the design basis as outlined in the updated safety analysis report.

71152 - Systems

NCV 05000482/2018002-02 Performance, Problem Closed Change Identification Management and Resolution A self-revealed Green NCV of 10 CFR Part 50, Criterion III, Design Control, was identified when the licensee failed to adequately recognize that the cable spreading room floor was a control building ventilation isolation boundary. Specifically, the licensee cut openings in the floor/ceiling between the 2,032 foot and 2,016 foot elevations of the control building and the impact on the control room envelopes ability to pressurize was not recognized. This was a primary contributor to the train B control room emergency ventilation system being unable to maintain the appropriate pressure in the control room envelope.

Description:

On March 5, 2018, the licensee performed Procedure STS PE-004, Aux Building and Control Room Pressure Test, Revision 16, and the train B control room emergency ventilation systems ability to pressurize the control room envelope and maintain pressure greater than or equal to 0.25 inches water gauge failed. Readings varied from nearly no measurable differential pressurerelative to outside airto approximately 0.15 inches water gauge. During this test, control building doors were not controlled.

Later tests on March 5, 2018, which maintained control of control building doors, had results that varied between 0.18 and 0.26 inches water gauge, with an average of 0.2258 inches water gauge. Troubleshooting was performed and, on March 6, 2018, an interim configuration associated with Design Change Package 14269, SGK05 Tech Spec Addition and Compensatory Modifications, was found to be impacting readings. Specifically, between September 17, 2017, and January 17, 2018, four approximately 2 foot by 2 foot openings were cut in the floor/ceiling between the 2,032 foot and 2,016 foot elevations of the control building to support ongoing ductwork installation.

On January 17, 2018, after penetrations for the modification were completed, compensatory measures consisting of steel plates covering the four floor openings were in place until ductwork installation began on February 19, 2018. These compensatory measures were put in place for fire, flood, and other functional concerns. On February 12, 2018, while the compensatory measures were in place, the train A control room emergency ventilation system successfully pressurized the control room envelope to 0.38 inches water gauge, demonstrating that the compensatory measures were adequate for maintaining control room envelope pressurization capability when in place.

Surveillance testing was performed for trains A and B of the control room emergency ventilation system on March 15, 2018, and the control room envelope was pressurized to 0.3448 and 0.3695 inches water gauge, respectively, which met surveillance requirements.

The system was restored to operable on March 16, 2018.

The inspectors reviewed the licensees cause evaluation, which determined that the probable causes of the issue were inadequate identification of control building ventilation isolation boundaries in WCRE-35, Boundary Matrix, Revision 0, and control of conditions during STS PE-004. Specifically, the inspectors also determined that the 2,016 foot to 2,032 foot elevation breaches were a primary contributor to the failure of the control room emergency ventilation system to maintain adequate control room envelope pressure. The inspectors noted that WCRE-35, which was referenced during modification work for Design Change Package 14269, did not identify the barriers between the 2,016 and 2,032 foot elevations of the control building as control building ventilation isolation boundaries. WCRE-35 was a new document that was first approved on November 30, 2016, and was created from A, Boundary Matrix, of AP 10-104, Breach Authorization, Revision 35.

WCRE-35 notes, The information in the attachment has been copied directly from the procedure Attachment A, but when there were discrepancies identified the information has been verified and updated. The inspectors determined that the creation of the new WCRE-35 document was an opportunity for the licensee to recognize the subject boundarys importance and categorize the barrier as a control building ventilation isolation boundary.

Corrective Actions: The licensee completed Revision 3 of WCRE-35 on April 16, 2018, which reflects additional control building ventilation isolation boundaries, essential reading was issued, and other actions were performed to improve control room envelope pressurization margin.

Corrective Action Reference: Condition Report 120056.

Performance Assessment:

Performance Deficiency: The failure to recognize control building ventilation isolation boundaries and meet the requirements of 10 CFR Part 50, Criterion III, Design Control, is a performance deficiency.

Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the design 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 control room emergency ventilation systems ability to maintain adequate pressurization of the control room envelope was adversely impacted after an ongoing ventilation modification breached the floor without compensatory measures in place.

Significance: 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 represents a degradation of the radiological barrier function provided for the control room and represents a degradation of the barrier function of the control room against smoke or a toxic atmosphere. Thus, a detailed risk evaluation is required.

The senior reactor analyst evaluated the subject performance deficiency and resulting plant conditions to determine the risk impact on the plant. The analyst identified that the control room emergency ventilation system is not a significant risk contributor, because it does not directly affect the core damage frequency, provided operators have a habitable environment.

Although the control room boundary was significantly degraded in the as-found condition, either train of the control room emergency ventilation system was capable of maintaining the control room envelope with some level of pressurization, based on multiple test results.

Therefore, while some deterioration of the control room environment could be expected, the control room emergency ventilation system appeared to be capable of maintaining a habitable environment throughout the relatively limited exposure period of the performance deficiency.

As a result, the increase in risk caused by the degraded condition of the control room envelope was negligible, and 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 ensure that individuals understood the importance of, and their role in, the change management process when WCRE-35 was recently revised and implemented. As a result, WCRE-35 did not identify all control building ventilation isolation boundaries.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires, in part, that for those structures, systems, and components to which this appendix applies, measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in 50.2 and as specified in the license application, are correctly translated into specifications, drawings, procedures, and instructions.

Contrary to the above, until April 16, 2018, for quality-related components associated with the control building, to which 10 CFR Part 50, Appendix B, applies, the licensee failed to assure that applicable regulatory requirements and the design basis, as defined in 50.2 and as specified in the license application, are correctly translated into specifications, drawings, procedures, and instructions. Specifically, the licensee failed to ensure that all control building ventilation isolation boundaries were adequately identified in WCRE-35, Boundary Matrix, which the station uses to identify boundary functions, such that the control room envelope could be adequately pressurized in accordance with design basis requirements.

Disposition: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

Failure to Adequately Implement Instrumentation and Controls Surveillance Procedures Cornerstone Significance Cross-cutting Report Section Aspect Initiating Green [H.2] - Human

71152 - Events

NCV 05000482/2018002-03 Performance, Problem Closed Field Presence Identification and Resolution A self-revealed Green NCV of 10 CFR Part 50, Criterion V, Instructions, Procedures, and Drawings, was identified when the licensee failed to adequately implement surveillance procedures that affected safety-related equipment and plant stability. Specifically, the licensee failed to adequately implement testing and calibration procedures for pressurizer level instrumentation. This resulted in two letdown isolation signals, securing of pressurizer heaters, and a pressurizer level transient on March 29, 2018.

Description:

On March 29, 2018, the licensee was performing Procedure STS IC-503B, Pressurizer Level Instrumentation Channel Calibration, Revision 12. This surveillance procedure performs calibration and testing activities associated with three pressurizer level channels, one-at-a-time. To perform calibration of each channel, a control room operator selects away from the channel to be tested, which ensures the controlling pressurizer level channels are not being tested. This allows maintenance technicians to perform calibration and testing activities associated with the desired channel. Following calibration and testing of each channel, the channel is restored and actions are taken to select away from the next desired channel to be tested, which again ensures the controlling pressurizer level channels are not being tested.

During the testing on March 29, 2018, station personnel successfully completed the calibration of channel 459, which is located in the SB038 cabinet. The technicians then informed the control room operator they were moving to the next section of the procedure associated with channel 460, and the operator selected away from channel 460 in accordance with procedure. The technicians had flagged a switch to be manipulated in cabinet SB038, but had incorrectly flagged the switch for channel 459. As a result, channel 459 was again taken to the test position, but this channel was now a controlling pressurizer level channel since channel 460 was to be tested next. The instrument failed low, which resulted in an actual pressurizer level transientlevel got as high as approximately 63 percent from a normal level of approximately 56.6 percentisolation of letdown, and automatic de-energization of the pressurizer back-up heaters.

Step 8.3.3 of Procedure STS IC-503B stated, At C2-0847 (LS/460), PLACE BS-1 (LS/460A)to TEST position. This procedure step was not followed and the technicians did not adequately use human performance tools to ensure they were in the appropriate cabinet and flagging the appropriate channel, and supervision was not present when the inappropriate cabinet was flagged.

Operators responded to the transient using Off-Normal Procedure OFN SB-008, Instrument Malfunctions, Revision 45, reselected channel 460 as the controlling pressurizer level channel in accordance with the off-normal procedure, and an operator stated to the technician that they had received the 459 loop alarms. The technician then restored channel 459 from the test position without supervision and proceeded on in Procedure STS IC-503B.

Procedure OFN SB-008 had ensured that the alternate pressurizer level channel on the pressurizer level control selector switch was selected. The technician did not re-perform Step 8.3.1.b, which states, Place BB LS-459D, PZR LEV CRTL SEL switch to L459/L461 position, before proceeding with channel 460 testing. Thus, when channel 460 was taken to the test position, this caused a second actual pressurizer level transientlevel got as high as 63 percenta second letdown isolation signal (though it had not yet been restored), and a second automatic de-energization of the back-up heaters signal was received. Operators again responded to the transient and stabilized the plant. Additionally, following the second actual pressurizer level transient operators provided the order to the technician to, stop work.

The licensees evaluation determined that because of the risk associated with this task, supervisory oversight was required. Specifically, the qualitative risk screening performed for the task identified the need for leadership team member implementation oversight as a risk mitigating action. However, the oversight had not yet made it to the control room. The inspectors agreed with the licensees conclusions that the lack of oversight was the most significant contributor to both failures to follow procedures.

Corrective Actions: The transient was stabilized, work was stopped following the second event, an event review was conducted, a stand-down was initiated, technician qualifications were removed, communications were made to operations and the site, and an interim action was created to have an operations individual present during two-minute drills for any work performed in the cabinets in the back of the control room.

Corrective Action Reference: Condition Report 120807.

Performance Assessment:

Performance Deficiency: The failure to adequately implement the testing and calibration procedure for pressurizer level instrumentation on two occasions and meet the requirements of 10 CFR Part 50, Criterion V, Instructions, Procedures, and Drawings, was a performance deficiency. Specifically, procedures for pressurizer level instrumentation calibration were not followed on two occasions:

(1) when an instrumentation and control technician failed to take the appropriate channel to test in accordance with procedure; and

(2) when the individual failed to adequately verify the appropriate channels were selected in accordance with procedure on March 29, 2018. These actions failed the 459 level transmitter channel low inappropriately and then subsequently failed the 460 level transmitter channel low inappropriately, respectively.

Screening: The inspectors determined the performance deficiency was more than minor because it affected the human performance attribute of the Initiating Events Cornerstone and adversely affected the 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, the performance deficiency resulted in two separate actual pressurizer level transients, letdown isolation signals, and signals for automatic de-energization of the pressurizer back-up heaters.

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 was not a deficiency that caused a plant trip and did not cause the loss of mitigation equipment relied upon to transition the plant from the onset of a trip to stable plant shutdown (e.g. loss of condenser, loss of feedwater). Furthermore, there were no other events such as a high energy line break, internal flooding, or fire. 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 field presence in that senior managers did not ensure supervisory and management oversight of work activities. Specifically, managers and supervisors did not practice visible leadership in the field and during safety significant evolutions like performance of Procedure STS IC-503B by placing eyes on the problem, coaching, mentoring, reinforcing standards and reinforcing positive decision making practices and behaviors, which led to the multiple examples of failure to follow procedures.

Enforcement:

Violation: Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be accomplished in accordance with documented instructions, procedures, or drawings of a type appropriate to the circumstances.

(1) Procedure STS IC-503B, Pressurizer Level Instrumentation Channel Calibration, Revision 12, an Appendix B quality related procedure, provides instructions for performing pressurizer level instrument calibration testing. Procedure STS IC-503B, Step 8.3.3, requires that BS-1 (LS/460A) be placed in the test position. Contrary to the above, on March 29, 2018, BS-1 (LS/460A) was not placed in the test position.

Specifically, the 459 channel was placed in the test position inappropriately.

(2) Procedure STS IC-503B, Step 8.3.1.b, requires, in part, verification that BB LS-459D, the pressurizer level control selector switch, be placed in the L459/L461 position for channel 460 testing and calibration. Contrary to the above, on March 29, 2018, verification that BB LS-459D, the pressurizer level control selector switch, was placed in the L459/L461 position for channel 460 testing and calibration was not performed.

Specifically, testing and calibration of channel 460 occurred while channel 460 was selected as the controlling channel.

Disposition: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

On April 16, 2018, a reactor inspector from the Nuclear Regulatory Commissions (NRC)

Region IV office will perform the baseline inservice inspection at Wolf Creek Nuclear

Operating Station, using NRC Inspection Procedure 71111.08, "Inservice Inspection

Activities. Experience has shown that this inspection is a resource intensive inspection

both for the NRC inspector and your staff. The date of this inspection may change

dependent on the outage schedule you provide. In order to minimize the impact to your

onsite resources and to ensure a productive inspection, we have enclosed a request for

documents needed for this inspection. These documents have been divided into two

groups. The first group (Section A of the enclosure) identified information to be provided

prior to the inspection to ensure that the inspector is adequately prepared. The second

group (Section B of the enclosure) identifies the information the inspector will need upon

arrival at the site. It is important that all of these documents are up to date and complete in

order to minimize the number of additional documents requested during the preparation

and/or the onsite portions of the inspection.
