SUMMARY

IR 05000 482/20 17 0 01; 01/0 1/20 17 - 03/31/20 17; Wolf Creek Generating Station

Maintenance Effectiveness The inspection activities described in this report were performed between January 1 and March 31, 2017 , by the resident inspectors at Wolf Creek Generating Station and inspectors from the NRC's Region IV office. One finding of very low safety significance (Green)is documented in this report. This finding involved a violation of NRC requirements

. The significance of inspection findings is indicated by their color (i.e., Green , greater than Green, White, Yellow, or Red), determined using Inspection Manual Chapter 0609, "Significance Determination Process," dated April 29, 2015. Their cross-cutting aspects are determined using Inspection Manual Chapter 0310, "Aspects within the Cross-Cutting Areas," dated December 4, 2014. Violations of NRC requirements are dispositioned in accordance with the NRC Enforcement Policy.

The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG

-1649, "Reactor Oversight Proce ss ," dated July 2016.

Cornerstone: Mitigating Systems

Green.

The inspectors reviewed a Green, self-revealed non-cited violation of Technical Specification 5.4.1.a and Regulatory Guide 1.33 for the licensee's failure to provide adequate work instructions for preventive maintenance on safety-related equipment. Specifically, work instructions to inspect and clean the condensate drain lines on the class 1E air conditioner air handling units lacked guidance for adequately cleaning the drain line. This caused the unit to become non-functional. The licensee took the immediate corrective action to clear the clogged condensate drain line on SGK05B, and entered the issue in the corrective action program as Condition Report 106416. The failure to provide adequate work instructions for preventive maintenance on safety-related equipment is a performance deficiency.

This performance deficiency is more than minor, and therefore a finding, because it is associated with the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). In accordance with NRC Inspection Manual Chapter 0609, Appendix A, Exhibit 2, "Mitigating Systems Screening Questions," the inspectors determined this finding screened to Green

. The inspectors determined that the finding has a problem identification and resolution cross-cutting aspect of resolution because the organization did not take effective corrective actions to address issues in a timely manner commensurate with their safety significance. This issue is indicative of current performance because neither the preventive maintenance change process was substantively changed nor were human performance errors associated with the preventive maintenance change corrected, and the same resolution inadequacies that resulted in the inadequate preventive maintenance instructions would be expected to occur

[P.3]. (Section 1R1 2)3

PLANT STATUS

Wolf Creek Generating Station began the inspection period operating at full power. On February 9, 2017, operators reduced power to approximately 82 percent to complete planned main turbine valve cycle testing. Plant power was restored to approximately full power on February 10, 2017, and the plant operated at

, or near , full power for the rest of the period.

The inspectors reviewed the licensee's work practices to evaluate whether these may have played a role in the degradation of the SSCs. The inspectors assessed the licensee's characterization of the degradation in accordance with 10 CFR 50.65 (the Maintenance Rule), and verified that the licensee was appropriately tracking degraded performance and conditions in accordance with the Maintenance Rule.

These activities constituted completion of two maintenance effectiveness sample s, as defined in Inspection Procedure 71111.12.

b. Findings

Introduction.

The inspectors reviewed a Green, self-revealed non-cited violation of Technical Specification 5.4.1.a and Regulatory Guide 1.33 for the licensee's failure to provide adequate work instructions for preventive maintenance on safety

-related equipment. Specifically, work instructions to inspect and clean the condensate drain line on the train B class 1E air conditioner air handling unit lacked adequate guidance to clean the drain line. This resulted in the train B class 1E air conditioning unit becoming non-functional

.

Description.

On August 15, 2016, at 4:33 a.m., the train B class 1E air conditioning unit (SGK05B) was declared non

-functional when an operator discovered water on the floor near the air handling unit where one would not normally expect such a condition. This water was determined to be from condensate that had accumulated within the air handling unit and was leaking out of an access door seal. The condensate within the air handling unit had accumulated enough to wet the bottom of the fan motor within the unit. The direct cause of the accumulation of condensation in this air handling unit was determined to be a clogged condensate drain line. This line was cleared using pressurized water, the station started the unit for post maintenance testing on August 15, 2016, at 10:59 p.m., and the unit was declared functional at 11:35 a.m., on August 16, 2016. Prior to this occurrence, on August 7, 2016, at 3:52 a.m., the train A control room air conditioning unit (SGK04A) was declared inoperable due to the discovery of condensation accumulating inside the air handling unit for this air conditioner. This issue was initially found by the operator on rounds when the operator noted the absence of water dripping from the condensate drain line as it normally does during operation. The condensation within the air handling unit had accumulated enough to wet the bottom of the fan motor. The direct cause of the accumulation of condensate within the air handling unit was determined to be a partially clogged condensate drain line. During

operation, a small vacuum is created within the air handling unit and this vacuum, coincident with a partially clogged drain line, prevented condensate from draining from the unit. This line was partially cleared using pressurized water and the unit was de clared operable at 5:50 p.m. on August 7, 2016. Inspectors challenged the licensee on their assessment that the unit was operable and not degraded due to only partially clearing the drain line. The licensee agreed, and revised their operability determination to operable but degraded.

As part of a basic cause evaluation completed in September 2016, the licensee determined that the condensate drain lines had clogged on these units several times in the past and had also occurred on the train B control room air conditioning unit (SGK04B). A total of twelve incidents since 1998 were reported.

Initial corrective actions in 1998, implemented a preventive maintenance strategy for the control room air conditioning units and the class 1E air conditioning units for their condensate drain lines. This preventive maintenance activity did not initially provide guidance to check the drain lines for obstructions. In July 2000, after the train A control room air conditioning unit experienced a clogged condensate drain line, the preventive maintenance instructions were updated to request maintenance personnel to pour one gallon of water down the drain line to verify adequate drainage flow. However, these instructions did not include guidance on what was an acceptable flow rate.

In 2008, after continuing to have issues with clogging condensate drain lines, the preventive maintenance instructions were updated to require disassembly of the drain lines by maintenance personnel to inspect and thoroughly clean the drain lines.

The ability to disassemble the condensate drain line was only possible on SGK05A due to a threaded union being present in the drain line. The other three units; SGK05B, SGK04A, and SGK04B, did not have a threaded union in the drain line. Because of this, a recommendation was made in 2012 to change the preventive maintenance instructions. The preventive maintenance instructions for the other three units were subsequently essentially reverted to the previous instructions that utilized the flushing water technique and did not require the lines to always be cleaned, even though the preventive maintenance tasks had previously been changed in 2008 to resolve ongoing issues. The licensee's basic cause evaluation determined that the most probable cause of the collection of debris in the condensate drain lines was lack of guidance in the preventive maintenance work instructions to adequately clean the drain lines to determine if blockage s exist and to remove them. The inspectors questioned whether any substantive changes to the preventive maintenance change process had occurred subsequent to 2012 or if any new actions were planned, and the inspectors questioned whether any corrective actions had been taken or were planned related to any human performance issues associated with the inadequate preventive maintenance change in 2012. The licensee confirmed that neither previous nor planned actions addressed the programmatic or human performance issues that resulted in inadequate resolution of the inadequate preventiv e maintenance task issue. As a result, the issue is indicative of current performance, and the licensee documented Condition Report 112754 to address the inspectors' concerns.

The licensee entered this issue into its corrective action program as Condition Reports 106262 , 106416, and 112754. Condition Report 106416 documented completion of actions to improve the preventive maintenance work instructions to require the use of pressure (air and/or water) to clean/purge the condensate drain lines.

Analysis.

The failure to provide adequate work instructions for preventive maintenance on safety-related equipment is a performance deficiency. Th is performance deficiency is more than minor, and therefore a finding, because it is associated with the procedure quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage).

Specifically, work instructions for preventive maintenance on the condensate drain line for SGK05B were inadequate

, and as a result, SGK05B condensate drain lines became clogged and SGK05B was declared non

-functional

. The inspectors evaluated 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 that maintained its operability or functionality; 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; 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 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Therefore, the inspectors determined the finding was of very low safety significance (Green).

The inspectors determined that the finding has a problem identification and resolution cross-cutting aspect in the area of resolution because the organization did not take effective corrective actions to address issues in a timely manner commensurate with their safety significance. Specifically, in 2012 the preventive maintenance instructions for the SGK05B, SGK04A, and SGK04B units, which were created in 2008 to address continuing condensate drain line clogging issues, were essentially reverted back to the previous inadequate instructions. This issue is indicative of current performance because neither the preventive maintenance change process was substantively changed

nor were human performance errors associated with the preventive maintenance change corrected, and the same resolution inadequacies that resulted in the inadequate preventive maintenance instructions would be expected to occur

[P.3].

Enforcement.

Technical Specification 5.4.1.a requires, in part, that procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2.

Section 9.a of Appendix A to Regulatory Guide 1

.33 , Revision 2, requires, 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 ci rcumstances."

The licensee established Procedure AP 1 6B-003, "Planning and Scheduling Preventive Maintenance," which provides direction for implementing the preventive maintenance program to meet the Regulatory Guide 1.33 requirement. Section 6.2 of Procedure AP 16B

-003 requires, in part, that preventive maintenance activities be developed by considering, in part, equipment history, operating experience, and component functional importance. Contrary to the above, until December 15, 2016, preventive maintenance activities were not developed by adequately considering equipment history, operating experience, and component functional importance. Specifically, preventive maintenance activity 28380 for cleaning and inspecting the drain line on SGK05B, an activit y affecting quality, was not appropriate to the circumstance s. As a result, the train B class 1E air conditioning unit (SGK05B) was declared non

-functional on August 15, 2016. The licensee took the immediate corrective action to clear the clogged condensate drain line on SGK05B and has completed corrective action s to improve the preventive maintenance instructions. The licensee entered this issue into the corrective action program as Condition Reports 106262 , 106416 , and 112754. This violation is being treated as an NCV, consistent with Section 2.3.2.a of the Enforcement Policy

NCV 05000482/201 7 00 1-01, "Failure to Provide Adequate Work Instructions for Preventive Maintenance

."

1 R 13 Maintenance Risk Assessments and Emergent Work Control (71111.13)

a. Inspection Scope

The inspectors reviewed three risk assessments performed by the licensee prior to changes in plant configuration and the risk management actions taken by the licensee in response to elevated risk:

January 23, 2017 , planned maintenance for train A control room air

-conditioning unit and train A safety injection pump January 31

, 2017, planned maintenance for train B essential service water pump and train B emergency diesel generator February 21 and 22, 2017, planned 7-day maintenance window f or train A emergency diesel generator The inspectors verified that these risk assessment s were performed timely and in accordance with the requirements of 10 CFR 50.65 (the Maintenance Rule) and plant procedures. The inspectors reviewed the accuracy and completeness of the licensee's risk assessment s and verified that the licensee implemented appropriate risk management actions based on the result of the assessment s. Additionally, on January 17, 2017, the inspectors also observed portions of steam generator atmospheric relief valve A controller replacement emergent work activities that had the potential to affect the functional capability of mitigating systems

. The inspectors verified that the licensee appropriately developed and followed a work plan for these activities. The inspectors verified that the licensee took precautions to minimize the impact of the work activities on unaffected SSCs.

These activities constitute d completion of four maintenance risk assessments and emergent work control inspection sample s , as defined in Inspection Procedure 71111.13.

b. Findings

No findings were identified.

1 R 15 Operability Determinations and Functionality Assessments (71111.15)

a. Inspection Scope

The inspectors reviewed five operability determinations and evaluations that the licensee performed for degraded or nonconforming SSCs:

4OA 5 Other Activities Temporary Instruction 2515/192, "Inspection of the Licensee's Interim Compensatory Measures Associated with the Open Phase Condition Design Vulnerabilities in Electric Power Systems

."

a. Inspection Scope

The objective of this performance based Temporary Instruction was to verify implementation of interim compensatory measures associated with an open phase condition design vulnerability in electric power systems for operating reactors. The inspectors conducted an inspection to determine if the licensee implemented the following interim compensatory measures. These compensatory measures are to remain in place until permanent automatic detection and protection schemes are installed and declared operable for the open phase condition design vulnerability. The inspectors verified the following:

The licensee identified and discussed with plant staff the lessons

-learned from the open phase condition events at the U.S. operating plants including the Byron Station open phase condition and its consequences. This included conducting operator training for promptly diagnosing, recognizing consequences, and responding to an open phase condition.

The licensee updated plant operating procedures to help operators promptly diagnose and respond to open phase conditions on off

-site power sources credited for safe shutdown of the plant.

The licensee established and implemented periodic walkdown activities to inspect switchyard equipment such as insulators, disconnect switches, and transmission line and transformer connections associated with the off

-site power circuits to detect a visible open phase condition.

The licensee ensured that routine maintenance and testing activities on switchyard components have been implemented and maintained.

As part of the maintenance and testing activities, the licensee assessed and managed plant risk in accordance with 10 CFR 50.65(a)(4) requirements.

b. Findings

No findings were identified.

4OA 6 Meetings, Including Exit

Exit Meeting Summary
