  - 2 -  SUMMARY  IR 05000482/2014003; 03/29/2014 - 06/27/2014; Wolf Creek Generating Station, Integrated Resident and Regional Report; Maintenance Risk Assessments and Emergent Work Control.   
The inspection activities described in this report were performed between March 29 and June 27, 2014, by the resident inspectors at Wolf Creek Generating Station and inspectors from
the Nuclear Regulatory Commission Region IV office.  One finding of very low safety significance (Green) is documented in this report.  This finding involved a violation of Nuclear Regulatory Commission requirements.  The significance of inspection findings is indicated by their color (Green, White, Yellow, or Red), which is determined using Inspection Manual
Chapter 0609, "Significance Determination Process."  Their cross-cutting aspects are
determined using Inspection Manual Chapter 0310, "Components Within the Cross-Cutting
Areas."  Violations of NRC requirements are dispositioned in accordance with the Nuclear Regulatory Commission Enforcement Policy.  The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG 1649, "Reactor Oversight Process."
Findings  No findings were identified.
Licensee Identified Findings 
No findings were identified. 
  - 3 -  PLANT STATUS  Wolf Creek began the inspection period with the unit in Mode 5 (cold shutdown) for a planned
mid-cycle outage.  On May 8, 2014, the reactor was restarted then promptly shut down due to a leaking steam generator bowl drain valve inside containment.  On May 10, 2014, the reactor
was again restarted and promptly shut down due to a reactor coolant pump oil leak inside
containment.  On May 13, 2014, the reactor was restarted successfully, reached 100 percent
power on May 15, 2014, and remained at that power level for the remainder of the inspection
period.
REPORT DETAILS  1. REACTOR SAFETY  Cornerstones:  Initiating Events, Mitigating Systems, and Barrier Integrity 
1R01 Adverse Weather Protection (71111.01)
  Summer Readiness for Offsite and Alternate AC Power Systems  a. Inspection Scope 
On May 2, 2014, the inspectors completed an inspection of the station's off-site and
alternate-ac power systems.  The inspectors inspected the material condition of these systems, including transformers and other switchyard equipment to verify that plant features and procedures were appropriate for operation and continued availability of off-
site and alternate-ac power systems.  The inspectors reviewed outstanding work orders
and open condition reports for these systems.  The inspectors walked down the switchyard to observe the material condition of equipment providing off-site power sources.  The inspectors verified that the licensee's procedures included appropriate measures to monitor and maintain availability and reliability of the off-site and alternate-ac power systems.
These activities constituted one sample of summer readiness of off-site and alternate-ac
power systems, as defined in Inspection Procedure 71111.01.  b. Findings

evaluated control of transient combustibles and ignition sources, fire detection and
suppression systems, manual firefighting equipment and capability, passive fire
protection features, and compensatory measures for degraded conditions.  These activities constituted four quarterly inspection samples, as defined in Inspection Procedure 71111.05.  b. Findings  No findings were identified.   
  - 5 -  .2 Annual Inspection  a. Inspection Scope  On June 27, 2014, the inspectors completed their annual evaluation of the licensee's fire
brigade performance.  This evaluation included observation of an unannounced fire drill
for 2016, control building non-vital switchgear room B on June 27, 2014.
During this drill, the inspectors evaluated the capability of the fire brigade members, the leadership ability of the brigade leader, the brigade's use of turnout gear and fire-fighting equipment, and the effectiveness of the fire brigade's team operation.  The inspectors
also reviewed whether the licensee's fire brigade met NRC requirements for training,
dedicated size and membership, and equipment.
These activities constituted one annual inspection sample, as defined in Inspection Procedure 71111.05.  b. Findings  No findings were identified.  1R11 Licensed Operator Requalification Program and Licensed Operator Performance (71111.11)  Review of Licensed Operator Requalification  a. Inspection Scope 
On June 18, 2014, the inspectors evaluated a simulator scenario performed by an
operating crew.  The inspectors assessed the performance of the operators and the evaluators' critique of their performance.   
These activities constitute completion of one quarterly licensed operator requalification
program sample, as defined in Inspection Procedure 71111.11.  b. Findings  No findings were identified.  1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13)  a. Inspection Scope 
The inspectors reviewed two 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:
* May 19-25, 2014, train A essential service water and emergency diesel generator planned maintenance outage 
  - 6 -  * June 16-22, 2014, train B safety injection planned maintenance outage and train B containment spray planned maintenance outage  The inspectors verified that these risk assessments 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 assessments and verified that the licensee implemented appropriate risk management actions based on the result of the assessments.
The inspectors also observed portions of one emergent work activities that had the
potential to affect the functional capability of mitigating systems:  * June 9-11, 2014, emergency diesel generator B governor testing failure and replacement 
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 structures, systems, and components (SSCs). 
Additionally, the inspectors reviewed the risk assessments associated with two planned
maintenance activities performed during a time in the outage when the primary plant was
in a water-solid condition that resulted in unplanned pressure transients.    * March 14, 2014, reactor coolant system pressure transient during bus switching  * April 1, 2014, reactor coolant system pressure transient during motor-operated valve testing  These activities constitute completion of four maintenance risk assessments and
emergent work control inspection samples, as defined in Inspection Procedure 71111.13.  (Note: The March 14, 2014, sample was counted in Inspection Report 2014002).
b. Findings  No findings were identified.
1R15 Operability Determinations and Functionality Assessments (71111.15)  a. Inspection Scope 
The inspectors reviewed four operability determinations that the licensee performed for
degraded or nonconforming SSCs:
* April 5, 2014, operability determination of train B emergency diesel generator heating, ventilation, and air conditioning inlet damper hydramotor oil analysis  * April 23, 2014, operability determination of containment cooler corrosion extent of condition 
  - 7 -  * May 19, 2014, operability determination of NB01 under voltage surveillance failure  * June 11, 2014, operability determination of train B emergency diesel generator governor hydraulic actuator SKJ09B  The inspectors reviewed the timeliness and technical adequacy of the licensee's evaluations.  Where the licensee determined the degraded SSC to be operable, the inspectors verified that the licensee's compensatory measures were appropriate to provide reasonable assurance of operability.  The inspectors verified that the licensee
had considered the effect of other degraded conditions on the operability of the
degraded SSC.  In the case of the containment cooler issues, the inspectors obtained the assistance of
specialist inspectors from the Region IV office and experts from the Office of Nuclear
Reactor Regulation.  The NRC conducted several calls with licensee technical and
management personnel.  Based on NRC concerns, the licensee decided to perform
hydrostatic testing of the remaining coolers to provide provide test data to support continued operabililty with continuing pitting corrosion.  The inspectors observed one of the pressure tests and reviewed the revised operability determination. 
These activities constitute completion of four operability review samples, as defined in
Inspection Procedure 71111.15.  b. Findings 
No findings were identified.  1R19 Post-Maintenance Testing (71111.19)  a. Inspection Scope

No findings were identified. 
1R20 Refueling and Other Outage Activities (71111.20)  a. Inspection Scope 
During the station's mid-cycle outage that concluded on May 13, 2014, the inspectors evaluated the licensee's outage activities.  The inspectors verified that the licensee considered risk in developing and implementing the outage plan, appropriately managed personnel fatigue, and developed mitigation strategies for losses of key safety functions. 
This verification included the following:
* Review of the licensee's outage plan prior to the outage * Monitoring of shut-down and cool-down activities * Verification that the licensee maintained defense-in-depth during outage activities * Monitoring of heat-up and startup activities  These activities constitute completion of one planned outage sample outage activities
sample, as defined in Inspection Procedure 71111.20.  b. Findings 
No findings were identified.  1R22 Surveillance Testing (71111.22)  a. Inspection Scope 
The inspectors observed six risk-significant surveillance tests and reviewed test results
to verify that these tests adequately demonstrated that the SSCs were capable of
performing their safety functions:  In-service tests:
* April 25, 2014, accumulator vent valve EPV0109  Reactor Coolant System Leak Detection:
* May 31, 2014, reactor coolant system water inventory balance  Other surveillance tests:  * March 28-29, 2014, train A engineered safety features actuating safety testing  * April 25-28, 2014, station blackout diesel functional testing * May 6, 2014, containment closeout walkdown * May 19, 2014, reactor coolant system xenon-133 specific activity determination 
  - 9 -  The inspectors verified that these tests met technical specification requirements, that the licensee performed the tests in accordance with their procedures, and that the results of
the test satisfied appropriate acceptance criteria.    These activities constitute completion of six surveillance testing inspection samples, as
defined in Inspection Procedure 71111.22.  b. Findings  No findings were identified.  Cornerstone:  Emergency Preparedness
1EP6 Drill Evaluation (71114.06) 
Emergency Preparedness Drill Observation  a. Inspection Scope  The inspectors observed an emergency preparedness drill on June 18, 2014, to verify the adequacy and capability of the licensee's assessment of drill performance.  The
inspectors reviewed the drill scenario, observed the drill from the simulator and
emergency operations facility, and attended the post-drill critique.  The inspectors
verified that the licensee's emergency classifications, off-site notifications, and protective action recommendations were appropriate and timely.  The inspectors verified that any emergency preparedness weaknesses were appropriately identified by the licensee in the post-drill critique and entered into the corrective action program for resolution.
These activities constitute completion of one emergency preparedness drill observation
sample, as defined in Inspection Procedure 71114.06.

  - 14 -  4OA1 Performance Indicator Verification (71151)  .1 Reactor Coolant System Specific Activity (BI01)  a. Inspection Scope  The inspectors reviewed the licensee's reactor coolant system chemistry sample analyses for the period of April 1, 2013, through March 31, 2014, to verify the accuracy
and completeness of the reported data.  The inspectors reviewed the surveillance paperwork for the reactor coolant system sample taken on May 19, 2014.  The inspectors used definitions and guidance contained in Nuclear Energy Institute
Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7,
to determine the accuracy of the reported data.
These activities constituted verification of the reactor coolant system specific activity performance indicator, as defined in Inspection Procedure 71151.    b. Findings  No findings were identified.  .2 Reactor Coolant System Identified Leakage (BI02)  a. Inspection Scope  The inspectors reviewed the licensee's records of reactor coolant system identified leakage for the period of April 1, 2013 through March 31, 2014 to verify the accuracy and
completeness of the reported data.  The inspectors reviewed the performance
of STS BB-006 "RCS Water Inventory Balance" on May 31, 2014.  The inspectors used
definitions and guidance contained in Nuclear Energy Institute Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7, to determine the accuracy of the reported data.
These activities constituted verification of the reactor coolant system leakage
performance indicator, as defined in Inspection Procedure 71151.    b. Findings 
No findings were identified.  4OA2 Problem Identification and Resolution (71152) 
.1 Routine Review  a. Inspection Scope 
Throughout the inspection period, the inspectors performed daily reviews of items entered into the licensee's corrective action program and periodically attended the licensee's condition report screening meetings.  The inspectors verified that licensee
personnel were identifying problems at an appropriate threshold and entering these
problems into the corrective action program for resolution.  The inspectors verified that 
  - 15 -  the licensee developed and implemented corrective actions commensurate with the significance of the problems identified.  The inspectors also reviewed the licensee's
problem identification and resolution activities during the performance of the other inspection activities documented in this report.  b. Findings 
No findings were identified.
.2 Semiannual Trend Review  a. Inspection Scope  To verify that the licensee was taking corrective actions to address identified adverse trends that might indicate the existence of a more significant safety issue, the inspectors reviewed corrective action program documentation associated with the following
licensee-identified trends: 
* High backlogs in the design implementation and configuration control process area  Also, the inspectors identified the following trends that might indicate the existence of a more significant safety issue, and reviewed the licensee's response to them: 
* Inadequate technical verification and validation of temporary and permanent plant modifications  * The licensee's corrective action program group is not trending data at a station-wide level (i.e., above the department level), nor are they prioritizing departmental issues and trends which are significantly affecting overall station
performance  The NRC identified a theme in NRC inspection findings with cross-cutting aspects in maintaining design margins [H.6] during the 2013 End Of Cycle Assessment.  The
inspectors reviewed the licensee's response to that trend to verify that the licensee was
taking appropriate actions to address it.  These activities constitute completion of one semiannual trend review sample, as
defined in Inspection Procedure 71152.
b. Observations and Assessments  The inspectors' review of the trends identified above produced the following observations
and assessments: 
* Design Control Backlogs.  In July of 2013, an industry group assessment of station performance noted an unusually high number of open design change packages.  The backlog included approximately 1700 change packages, some
open since the early 1990s, including some SSCs with multiple open design changes.  Some change packages had targeted completion dates that were 
  - 16 -  beyond the expiration date of the plant operating license.  Historically, the station has had challenges with design control, as noted in NRC inspection reports.
The licensee performed an apparent cause evaluation under Condition Reports 72164, 72166, and 72167 to identify the organizational causes.  Among
the licensee's conclusions, management oversight of configuration control was
lacking, there was not an awareness of the vulnerability created by incomplete
configuration changes, and there was no single owner of design change products
to ensure configuration management documents are kept up to date.  The licensee took corrective actions to develop a configuration management health plan to improve the design control program as well as developing a
comprehensive backlog reduction strategy.  The inspectors also noted that the
licensee performed an aggregate risk assessment of the backlog to ensure that
items with more significant safety impacts were addressed more quickly.  The inspectors also noted that the backlog reduction program has reduced the number of open change packages to 400 at the end of June 2014, with a goal of
less than 200 planned by January 2015.
* Findings with Design Margins Cross Cutting Aspect [H6].  A theme in findings with cross-cutting aspects in the area of maintaining design margins was identified during the NRC's 2013 End of Cycle Assessment for Wolf Creek.  The licensee performed an apparent cause evaluation under Condition Reports 74508 and 78794.  The inspectors noted that this trend was related to
the larger problem of backlog management.  Because this trend is related to
other improvement efforts, the inspectors noted that the licensee has evaluated
and taken actions related to this theme in the areas of corrective action,
preventive maintenance, and procedure revision backlog reductions under Condition Reports 62394, 68194, and 78708.  Most of the backlog improvement efforts were making a notable reduction.  The inspectors observed that most
backlog reduction efforts remained on target through the mid-cycle 20 outage in
March and April of 2014.  Overall outage management and scope control
performance improvement was observed, and as a result, the corrective action and work order backlogs did not see the growth observed during previous outages.  The licensee has taken corrective actions to establish and validate new
internal performance indicators for the engineering and maintenance
departments.  Furthermore the licensee has scheduled actions to track these
new indicators and backlogs to specific goals based on industry standards in the
future.  Also, while completing this trend review, the inspectors identified the following trends
that the licensee had not previously identified.  The inspectors also reviewed the
licensee's response to these trends: 
* Quality of Plant Modifications.  Over the past 2 years, Wolf Creek has been implementing a large number of modifications.  Additional non-safety related diesel generators and an auxiliary feed water pump were added to improve plant safety.  The plant has also been addressing long standing corrosion and water
hammer issues in the essential service water system by replacing piping above
and below ground.  Obsolete analog controllers have been replaced with digital
control systems.  However, the inspectors have observed a number of plant events and equipment failures associated with inadequate technical validation 
  - 17 -  and verification associated with these modifications.  On May 2, 2013, an unplanned and uncontrolled 11 percent power increase occurred as a result of operator training deficiencies while swapping from the full arc to partial arc steam admission shortly after
installing the new Westinghouse Ovation digital turbine controls.  It was
subsequently determined that additional functions and flexibilities of the
new digital control system allowed operators to manipulate the plant in
configurations prohibited by the old analog system, and that system response varied with power level, but this was not recognized and incorporated into procedures and training.  Condition Report 68711, 
Non-Cited Violation NCV 05000482/2013003-05.
  On May 28, 2013, and again on September 5, 2013, the turbine driven auxiliary feed water pump control system failed unexpectedly, rendering the pump incapable of operation.  The digital control system positioner
locked up and required replacement.  It was later determined that an
additional unused input to the positioner was experiencing noise, and if
the noise came in at a certain point in the digital computer program's subroutine, the control software would crash.  The problem was fixed by jumpering out the unused input connection and a vendor technical bulletin
was issued to correct vulnerabilities at other nuclear power plants utilizing
the same control system.  Condition Reports 69721, 69754, and 73624.
  On April 25, 2014, during station blackout diesel generator testing, the licensee was unable to connect the train A Class 1E 4kV distribution bus to the station blackout diesel generators due to a protective relay
actuating to lock out the bus.  The diesels had been declared functional
and were credited in performance indicators and probabilistic risk
assessment models since October 2013, when construction was completed but testing had not been fully completed.  Troubleshooting as a result of the failed test found incorrect wiring of a protective relay to be
the cause.  Extent of condition inspections found that the train B bus
connection was also wired incorrectly, and neither safety related bus
would have been able to have been powered from the station blackout
diesel generators.  The licensee had intended to perform testing during the previous refueling outage, but construction delays caused work to extend beyond the outage.  Plant conditions for this test necessitated the
plant be shut down.  The inspectors had engaged the licensee concerning
their testing plan when construction was complete, but the licensee
concluded that their quality checks were adequate to have a high confidence that testing to connect the generators to the safety buses would be adequate until plant conditions for the testing were available. 
The inspectors concluded that those quality checks were inadequate,
although this did not constitute a violation because the diesel generators
and protective relaying were non-safety equipment and were not credited
to meet any regulatory requirements.  Condition Report 83379.   
  - 18 -  Not all of the validation and verification oversights resulted in plant events or failures.  Some of the items were caught very late in the planning process,
but still impacted regulatory commitments.  In February of 2014 the licensee commitment to correct long standing water hammer conditions in the essential service water system was
delayed.  The 2010 and 2012 Problem Identification and Resolution
inspections have assessed cited violations regarding long-standing
essential service water corrosion and water hammer issues not being addressed in a timely manner.  Wolf Creek responded on the docket and committed to fixing the essential service water corrosion and water
hammer issues by the spring 2014 mid-cycle outage.  However, after
over 3 years of planning, shortly before a modification was to be installed
to correct the water hammer, it was discovered that the mitigating strategy would invalidate the essential service water design basis safety function to provide a source of auxiliary feed water during a design basis external
event that compromises the condensate storage tank.  This was
documented in Condition Reports 53443 and 79619.  The licensee
concluded that there was inadequate contractor oversight during the modification development process.  A revised modification was tentatively rescheduled for the next refueling outage.
  On March 30, 2014, a containment cooler tube bundle failed (small tube leaks) as a result of water hammer during the engineered safety features
actuation system testing.  A similar failure occurred when the opposite train was tested a few weeks later.  While reviewing the cause evaluation, the inspectors noted the failure mechanism was due to a combination of
pitting corrosion and sudden pressure spike during the essential service
water system water hammer.  The ispectors determined that corrective
actions to address corrosion in carbon steel essential service water piping had not addressed the copper-nickel containment cooler tubes.  The inspectors reviewed the history of containment cooler degradation and
noted that all 48 of the tube bundles had already been replaced due to
widespread degradation in the late 1990s, and now the 2nd generation like-for-like replacements were beginning to fail.  The problem was further
complicated because non-destructive testing to monitor corrosion was not possible because the cooler design and complex cooler geometry prevented this.  The licensee plans to correct the condition by replacing
all coolers dueing the next outage, then replacing the original design with
stainless steel cooler tubes that will allow for eddy current testing. 
Condition Reports 81809 and 82904.  On November 18, 2011, an NRC Component Design Basis Inspection assessed NCV 05000482/2010007-01 for the failure to properly analyze
the isolation between the safety-related and non-safety related portions of
the component cooling water system.  Portions of the non-safety piping
leading to the rad waste building are non-seismically qualified, and should they fail, could result in a loss of inventory greater than can be accommodated by the component cooling water surge tanks.  The
inspector noted that the licensee promptly manually isolated this piping
and has been working on installing a combination of check valves and 
  - 19 -  orifices, for the past four years.  The planned modification to correct this violation has been delayed a number of times since 2012 because the
licensee has found problems with the design.  Condition Reports 28237 and 85328. 
The inspectors determined that the licensee was aware of these issues
individually, but had not identified the collective trend.  The licensee wrote
Condition Report 85907 to evaluate and address this trend.
* Lack Trending and Prioritization above the Department Level.  In reviewing the station roll-up reports that record corrective action program activities at the station and departmental levels, the inspectors noted that the analytical trending ends at the departmental summaries.  The station corrective action staff was not
summarizing analytical trends across divisions, nor were they giving additional priority to departmental trends which were having a significant impact on station
performance.  (e.g. design control, procedure quality, etc.)      The inspectors reviewed additional documentation associated with station
improvement initiatives and determined that at a station level, senior leadership
was performing some station level trend analysis and setting station priorities
based on the available data, but this was being done outside the corrective action program, and was not proceduralized and therefore would not continue when the improvement initiatives were completed.  The licensee has written
Condition Report 85905 to evaluate and address this issue. 
The inspectors' assessment noted improved corrective action trending at the
department level.  The operations department continues to be a station leader in this area.  The maintenance and engineering departments have made notable advancements in the past year to improve the quality of their corrective action program work products.  The inspectors have also witnessed a significant
improving trend in the quality, detail, and technical rigor, of apparent cause
evaluations and root cause analyses performed by station personnel.  c. Findings  No findings were identified.
.3 Annual Follow-up of Selected Issues  a. Inspection Scope 
The inspectors selected one issues for an in-depth follow-up:
* On May 1, 2014, below ground essential service water piping replacement to correct long standing corrosion issues.  The inspectors assessed the licensee's problem identification threshold, cause
analyses, extent of condition reviews and compensatory actions.  The inspectors
reviewed modifications paperwork and observed pipe fitting and welding activities
in the field.  The inspectors verified that the licensee appropriately prioritized the 
  - 20 -  planned corrective actions and that these actions were adequate to correct the condition.  These activities constitute completion of one annual follow-up sample as defined in Inspection Procedure 71152. 
b. Findings 
No findings were identified.  4OA6 Meetings, Including Exit  Exit Meeting Summary  On June 5, 2014, the inspectors presented the results of the radiation safety inspection to  Mr. C. Reasoner, Engineering, Vice President, and other members of the licensee staff.  The
licensee acknowledged the issues presented.  The licensee confirmed that any proprietary information reviewed by the inspectors had been returned or destroyed.
On July 8, 2014, the inspectors presented the inspection results to Mr. A. Heflin, Chief Executive Officer, and other members of the licensee staff.  The licensee acknowledged the issues
presented.  The licensee confirmed that any proprietary information reviewed by the inspectors had been returned or destroyed.

                                          PLANT STATUS
Wolf Creek began the inspection period with the unit in Mode 5 (cold shutdown) for a planned
mid-cycle outage. On May 8, 2014, the reactor was restarted then promptly shut down due to a
leaking steam generator bowl drain valve inside containment. On May 10, 2014, the reactor
was again restarted and promptly shut down due to a reactor coolant pump oil leak inside
containment. On May 13, 2014, the reactor was restarted successfully, reached 100 percent
power on May 15, 2014, and remained at that power level for the remainder of the inspection
period.
                                        REPORT DETAILS
1.     REACTOR SAFETY
        Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
1R01 Adverse Weather Protection (71111.01)
        Summer Readiness for Offsite and Alternate AC Power Systems
  a.   Inspection Scope
        On May 2, 2014, the inspectors completed an inspection of the stations off-site and
        alternate-ac power systems. The inspectors inspected the material condition of these
        systems, including transformers and other switchyard equipment to verify that plant
        features and procedures were appropriate for operation and continued availability of off-
        site and alternate-ac power systems. The inspectors reviewed outstanding work orders
        and open condition reports for these systems. The inspectors walked down the
        switchyard to observe the material condition of equipment providing off-site power
        sources. The inspectors verified that the licensees procedures included appropriate
        measures to monitor and maintain availability and reliability of the off-site and alternate-
        ac power systems.
        These activities constituted one sample of summer readiness of off-site and alternate-ac
        power systems, as defined in Inspection Procedure 71111.01.
  b.   Findings
        No findings were identified.
1R04 Equipment Alignment (71111.04)
        Partial Walkdown
  a.  Inspection Scope
        The inspectors performed partial system walk-downs of the following risk-significant
        systems:
            *  April 7, 2014, residual heat removal shutdown cooling train B
                                                -3-
 
          *  April 7, 2014, control room air conditioning system and control room emergency
              ventilation system train B
          *  June 17, 2014, safety injection system train A
      The inspectors reviewed the licensees procedures and system design information to
      determine the correct lineup for the systems. They visually verified that critical portions
      of the systems or trains were correctly aligned for the existing plant configuration.
      These activities constituted three partial system walk-down samples as defined in
      Inspection Procedure 71111.04.
  b. Findings
      No findings were identified.
1R05 Fire Protection (71111.05)
.1    Quarterly Inspection
  a. Inspection Scope
      The inspectors evaluated the licensees fire protection program for operational status
      and material condition. The inspectors focused their inspection on four plant areas
      important to safety:
          *  May 1, 2014, radiological controlled area and health physics office space
          *  May 1, 2014, lower cable spreading room
          *  May 7, 2014, upper cable spreading room
          *  May 8, 2014, auxiliary feedwater pump room train A
      For each area, the inspectors evaluated the fire plan against defined hazards and
      defense-in-depth features in the licensees fire protection program. The inspectors
      evaluated control of transient combustibles and ignition sources, fire detection and
      suppression systems, manual firefighting equipment and capability, passive fire
      protection features, and compensatory measures for degraded conditions.
      These activities constituted four quarterly inspection samples, as defined in Inspection
      Procedure 71111.05.
  b. Findings
      No findings were identified.
                                              -4-
 
.2    Annual Inspection
  a. Inspection Scope
      On June 27, 2014, the inspectors completed their annual evaluation of the licensees fire
      brigade performance. This evaluation included observation of an unannounced fire drill
      for 2016, control building non-vital switchgear room B on June 27, 2014.
      During this drill, the inspectors evaluated the capability of the fire brigade members, the
      leadership ability of the brigade leader, the brigades use of turnout gear and fire-fighting
      equipment, and the effectiveness of the fire brigades team operation. The inspectors
      also reviewed whether the licensees fire brigade met NRC requirements for training,
      dedicated size and membership, and equipment.
      These activities constituted one annual inspection sample, as defined in Inspection
      Procedure 71111.05.
  b. Findings
      No findings were identified.
1R11 Licensed Operator Requalification Program and Licensed Operator Performance
      (71111.11)
      Review of Licensed Operator Requalification
  a. Inspection Scope
      On June 18, 2014, the inspectors evaluated a simulator scenario performed by an
      operating crew. The inspectors assessed the performance of the operators and the
      evaluators critique of their performance.
      These activities constitute completion of one quarterly licensed operator requalification
      program sample, as defined in Inspection Procedure 71111.11.
  b. Findings
      No findings were identified.
1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13)
  a. Inspection Scope
      The inspectors reviewed two 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:
          *  May 19-25, 2014, train A essential service water and emergency diesel generator
              planned maintenance outage
                                              -5-
 
        *  June 16-22, 2014, train B safety injection planned maintenance outage and train
            B containment spray planned maintenance outage
    The inspectors verified that these risk assessments 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 licensees
    risk assessments and verified that the licensee implemented appropriate risk
    management actions based on the result of the assessments.
    The inspectors also observed portions of one emergent work activities that had the
    potential to affect the functional capability of mitigating systems:
        *  June 9-11, 2014, emergency diesel generator B governor testing failure and
            replacement
    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 structures, systems, and
    components (SSCs).
    Additionally, the inspectors reviewed the risk assessments associated with two planned
    maintenance activities performed during a time in the outage when the primary plant was
    in a water-solid condition that resulted in unplanned pressure transients.
        *  March 14, 2014, reactor coolant system pressure transient during bus switching
        *  April 1, 2014, reactor coolant system pressure transient during motor-operated
            valve testing
    These activities constitute completion of four maintenance risk assessments and
    emergent work control inspection samples, as defined in Inspection Procedure 71111.13.

1R15 Operability Determinations and Functionality Assessments (71111.15)
  a. Inspection Scope
    The inspectors reviewed four operability determinations that the licensee performed for
    degraded or nonconforming SSCs:
        *  April 5, 2014, operability determination of train B emergency diesel generator
            heating, ventilation, and air conditioning inlet damper hydramotor oil analysis
        *  April 23, 2014, operability determination of containment cooler corrosion extent of
            condition
                                              -6-
 
        *  May 19, 2014, operability determination of NB01 under voltage surveillance
            failure
        *  June 11, 2014, operability determination of train B emergency diesel generator
            governor hydraulic actuator SKJ09B
    The inspectors reviewed the timeliness and technical adequacy of the licensees
    evaluations. Where the licensee determined the degraded SSC to be operable, the
    inspectors verified that the licensees compensatory measures were appropriate to
    provide reasonable assurance of operability. The inspectors verified that the licensee
    had considered the effect of other degraded conditions on the operability of the
    degraded SSC.
    In the case of the containment cooler issues, the inspectors obtained the assistance of
    specialist inspectors from the Region IV office and experts from the Office of Nuclear
    Reactor Regulation. The NRC conducted several calls with licensee technical and
    management personnel. Based on NRC concerns, the licensee decided to perform
    hydrostatic testing of the remaining coolers to provide provide test data to support
    continued operabililty with continuing pitting corrosion. The inspectors observed one of
    the pressure tests and reviewed the revised operability determination.
    These activities constitute completion of four operability review samples, as defined in
    Inspection Procedure 71111.15.
  b. Findings
    No findings were identified.
1R19 Post-Maintenance Testing (71111.19)

        *  April 23, 2014, reactor coolant pump C bump test and break away torque
        *  May 8, 2014, steam generator B bowl valve testing
    The inspectors reviewed licensing and design basis documents for the SSCs and the
    maintenance and post-maintenance test procedures. The inspectors observed the
    performance of the post-maintenance tests to verify that the licensee performed the tests
    in accordance with approved procedures, satisfied the established acceptance criteria,
    and restored the operability of the affected SSCs.
    These activities constitute completion of four post-maintenance testing inspection
    samples, as defined in Inspection Procedure 71111.19.
                                              -7-

  a. Inspection Scope
    During the stations mid-cycle outage that concluded on May 13, 2014, the inspectors
    evaluated the licensees outage activities. The inspectors verified that the licensee
    considered risk in developing and implementing the outage plan, appropriately managed
    personnel fatigue, and developed mitigation strategies for losses of key safety functions.
    This verification included the following:
        *    Review of the licensees outage plan prior to the outage
        *    Monitoring of shut-down and cool-down activities
        *    Verification that the licensee maintained defense-in-depth during outage activities
        *    Monitoring of heat-up and startup activities
    These activities constitute completion of one planned outage sample outage activities
    sample, as defined in Inspection Procedure 71111.20.
  b. Findings
    No findings were identified.
1R22 Surveillance Testing (71111.22)
  a. Inspection Scope
    The inspectors observed six risk-significant surveillance tests and reviewed test results
    to verify that these tests adequately demonstrated that the SSCs were capable of
    performing their safety functions:
    In-service tests:
        *    April 25, 2014, accumulator vent valve EPV0109
    Reactor Coolant System Leak Detection:
        *    May 31, 2014, reactor coolant system water inventory balance
    Other surveillance tests:
        *    March 28-29, 2014, train A engineered safety features actuating safety testing
        *    April 25-28, 2014, station blackout diesel functional testing
        *    May 6, 2014, containment closeout walkdown
        *    May 19, 2014, reactor coolant system xenon-133 specific activity determination
                                              -8-
 
    The inspectors verified that these tests met technical specification requirements, that the
    licensee performed the tests in accordance with their procedures, and that the results of
    the test satisfied appropriate acceptance criteria.
    These activities constitute completion of six surveillance testing inspection samples, as
    defined in Inspection Procedure 71111.22.
  b. Findings
    No findings were identified.
    Cornerstone: Emergency Preparedness
1EP6 Drill Evaluation (71114.06)
    Emergency Preparedness Drill Observation
  a. Inspection Scope
    The inspectors observed an emergency preparedness drill on June 18, 2014, to verify
    the adequacy and capability of the licensees assessment of drill performance. The
    inspectors reviewed the drill scenario, observed the drill from the simulator and
    emergency operations facility, and attended the post-drill critique. The inspectors
    verified that the licensees emergency classifications, off-site notifications, and protective
    action recommendations were appropriate and timely. The inspectors verified that any
    emergency preparedness weaknesses were appropriately identified by the licensee in
    the post-drill critique and entered into the corrective action program for resolution.
    These activities constitute completion of one emergency preparedness drill observation
    sample, as defined in Inspection Procedure 71114.06.
  b. Findings
    No findings were identified.

    No findings were identified.
2RS6 Radioactive Gaseous and Liquid Effluent Treatment (71124.06)
  a. Inspection Scope
    The inspectors evaluated whether the licensee maintained gaseous and liquid effluent
    processing systems and properly mitigated, monitored, and evaluated radiological
    discharges with respect to public exposure. The inspectors verified that abnormal
    radioactive gaseous or liquid discharges and conditions, when effluent radiation monitors
    are out-of-service, were controlled in accordance with the applicable regulatory
    requirements and licensee procedures. The inspectors verified that the licensees
    quality control program ensured radioactive effluent sampling and analysis adequately
    quantified and evaluated discharges of radioactive materials. The inspectors verified the
    adequacy of public dose projections resulting from radioactive effluent discharges. The
    inspectors interviewed licensee personnel and reviewed or observed the following items:
        *  Radiological effluent release reports since the previous inspection and reports
            related to the effluent program issued since the previous inspection
        *  Effluent program implementing procedures, including sampling, monitor setpoint
            determinations, and dose calculations

2RS7 Radiological Environmental Monitoring Program (71124.07)
  a. Inspection Scope
    The inspectors evaluated whether the licensees radiological environmental monitoring
    program quantified the impact of radioactive effluent releases to the environment and
    sufficiently validated the integrity of the radioactive gaseous and liquid effluent release
    program. The inspectors verified that the radiological environmental monitoring program
    was implemented consistent with the licensees technical specifications and offsite dose
    calculation manual, and that the radioactive effluent release program met the design
    objective in Appendix I to 10 CFR Part 50. The inspectors verified that the licensees
    radiological environmental monitoring program monitored non-effluent exposure
    pathways, was based on sound principles and assumptions, and validated that doses to
    members of the public were within regulatory dose limits. The inspectors reviewed or
    observed the following items:
        *  Annual environmental monitoring reports and offsite dose calculation manual
        *  Selected air sampling and dosimeter monitoring stations
        *  Collection and preparation of environmental samples
        *  Operability, calibration, and maintenance of meteorological instruments

2RS8 Radioactive Solid Waste Processing and Radioactive Material Handling, Storage,
      and Transportation (71124.08)
  a. Inspection Scope
      The inspectors evaluated the effectiveness of the licensees programs for processing,
      handling, storage, and transportation of radioactive material. The inspectors interviewed
      licensee personnel and reviewed the following items:
          *  The solid radioactive waste system description, process control program, and the
            scope of the licensees audit program
          *  Control of radioactive waste storage areas including container labeling/marking
            and monitoring containers for deformation or signs of waste decomposition

4OA1 Performance Indicator Verification (71151)
.1    Reactor Coolant System Specific Activity (BI01)
  a.  Inspection Scope
      The inspectors reviewed the licensees reactor coolant system chemistry sample
      analyses for the period of April 1, 2013, through March 31, 2014, to verify the accuracy
      and completeness of the reported data. The inspectors reviewed the surveillance
      paperwork for the reactor coolant system sample taken on May 19, 2014. The
      inspectors used definitions and guidance contained in Nuclear Energy Institute
      Document 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 7,
      to determine the accuracy of the reported data.
      These activities constituted verification of the reactor coolant system specific activity
      performance indicator, as defined in Inspection Procedure 71151.
  b.  Findings
      No findings were identified.
.2    Reactor Coolant System Identified Leakage (BI02)
  a. Inspection Scope
      The inspectors reviewed the licensees records of reactor coolant system identified
      leakage for the period of April 1, 2013 through March 31, 2014 to verify the accuracy and
      completeness of the reported data. The inspectors reviewed the performance
      of STS BB-006 RCS Water Inventory Balance on May 31, 2014. The inspectors used
      definitions and guidance contained in Nuclear Energy Institute Document 99-02,
      Regulatory Assessment Performance Indicator Guideline, Revision 7, to determine the
      accuracy of the reported data.
      These activities constituted verification of the reactor coolant system leakage
      performance indicator, as defined in Inspection Procedure 71151.
  b. Findings
      No findings were identified.
4OA2 Problem Identification and Resolution (71152)
.1    Routine Review
  a. Inspection Scope
      Throughout the inspection period, the inspectors performed daily reviews of items
      entered into the licensees corrective action program and periodically attended the
      licensees condition report screening meetings. The inspectors verified that licensee
      personnel were identifying problems at an appropriate threshold and entering these
      problems into the corrective action program for resolution. The inspectors verified that
                                              - 14 -
 
      the licensee developed and implemented corrective actions commensurate with the
      significance of the problems identified. The inspectors also reviewed the licensees
      problem identification and resolution activities during the performance of the other
      inspection activities documented in this report.
  b. Findings
      No findings were identified.
.2    Semiannual Trend Review
  a. Inspection Scope
      To verify that the licensee was taking corrective actions to address identified adverse
      trends that might indicate the existence of a more significant safety issue, the inspectors
      reviewed corrective action program documentation associated with the following
      licensee-identified trends:
          *  High backlogs in the design implementation and configuration control process
              area
      Also, the inspectors identified the following trends that might indicate the existence of a
      more significant safety issue, and reviewed the licensees response to them:
          *  Inadequate technical verification and validation of temporary and permanent
              plant modifications
          *  The licensees corrective action program group is not trending data at a station-
              wide level (i.e., above the department level), nor are they prioritizing
              departmental issues and trends which are significantly affecting overall station
              performance
      The NRC identified a theme in NRC inspection findings with cross-cutting aspects in
      maintaining design margins [H.6] during the 2013 End Of Cycle Assessment. The
      inspectors reviewed the licensees response to that trend to verify that the licensee was
      taking appropriate actions to address it.
      These activities constitute completion of one semiannual trend review sample, as
      defined in Inspection Procedure 71152.
  b. Observations and Assessments
      The inspectors review of the trends identified above produced the following observations
      and assessments:
          *  Design Control Backlogs. In July of 2013, an industry group assessment of
              station performance noted an unusually high number of open design change
              packages. The backlog included approximately 1700 change packages, some
              open since the early 1990s, including some SSCs with multiple open design
              changes. Some change packages had targeted completion dates that were
                                              - 15 -
 
    beyond the expiration date of the plant operating license. Historically, the station
    has had challenges with design control, as noted in NRC inspection reports.
    The licensee performed an apparent cause evaluation under Condition
    Reports 72164, 72166, and 72167 to identify the organizational causes. Among
    the licensees conclusions, management oversight of configuration control was
    lacking, there was not an awareness of the vulnerability created by incomplete
    configuration changes, and there was no single owner of design change products
    to ensure configuration management documents are kept up to date. The
    licensee took corrective actions to develop a configuration management health
    plan to improve the design control program as well as developing a
    comprehensive backlog reduction strategy. The inspectors also noted that the
    licensee performed an aggregate risk assessment of the backlog to ensure that
    items with more significant safety impacts were addressed more quickly. The
    inspectors also noted that the backlog reduction program has reduced the
    number of open change packages to 400 at the end of June 2014, with a goal of
    less than 200 planned by January 2015.
  *  Findings with Design Margins Cross Cutting Aspect [H6]. A theme in findings
    with cross-cutting aspects in the area of maintaining design margins was
    identified during the NRCs 2013 End of Cycle Assessment for Wolf Creek. The
    licensee performed an apparent cause evaluation under Condition
    Reports 74508 and 78794. The inspectors noted that this trend was related to
    the larger problem of backlog management. Because this trend is related to
    other improvement efforts, the inspectors noted that the licensee has evaluated
    and taken actions related to this theme in the areas of corrective action,
    preventive maintenance, and procedure revision backlog reductions under
    Condition Reports 62394, 68194, and 78708. Most of the backlog improvement
    efforts were making a notable reduction. The inspectors observed that most
    backlog reduction efforts remained on target through the mid-cycle 20 outage in
    March and April of 2014. Overall outage management and scope control
    performance improvement was observed, and as a result, the corrective action
    and work order backlogs did not see the growth observed during previous
    outages. The licensee has taken corrective actions to establish and validate new
    internal performance indicators for the engineering and maintenance
    departments. Furthermore the licensee has scheduled actions to track these
    new indicators and backlogs to specific goals based on industry standards in the
    future.
Also, while completing this trend review, the inspectors identified the following trends
that the licensee had not previously identified. The inspectors also reviewed the
licensees response to these trends:
  *  Quality of Plant Modifications. Over the past 2 years, Wolf Creek has been
    implementing a large number of modifications. Additional non-safety related
    diesel generators and an auxiliary feed water pump were added to improve plant
    safety. The plant has also been addressing long standing corrosion and water
    hammer issues in the essential service water system by replacing piping above
    and below ground. Obsolete analog controllers have been replaced with digital
    control systems. However, the inspectors have observed a number of plant
    events and equipment failures associated with inadequate technical validation
                                    - 16 -
 
and verification associated with these modifications.
      On May 2, 2013, an unplanned and uncontrolled 11 percent power
      increase occurred as a result of operator training deficiencies while
      swapping from the full arc to partial arc steam admission shortly after
      installing the new Westinghouse Ovation digital turbine controls. It was
      subsequently determined that additional functions and flexibilities of the
      new digital control system allowed operators to manipulate the plant in
      configurations prohibited by the old analog system, and that system
      response varied with power level, but this was not recognized and
      incorporated into procedures and training. Condition Report 68711,
      Non-Cited Violation NCV 05000482/2013003-05.
      On May 28, 2013, and again on September 5, 2013, the turbine driven
      auxiliary feed water pump control system failed unexpectedly, rendering
      the pump incapable of operation. The digital control system positioner
      locked up and required replacement. It was later determined that an
      additional unused input to the positioner was experiencing noise, and if
      the noise came in at a certain point in the digital computer programs
      subroutine, the control software would crash. The problem was fixed by
      jumpering out the unused input connection and a vendor technical bulletin
      was issued to correct vulnerabilities at other nuclear power plants utilizing
      the same control system. Condition Reports 69721, 69754, and 73624.
      On April 25, 2014, during station blackout diesel generator testing, the
      licensee was unable to connect the train A Class 1E 4kV distribution bus
      to the station blackout diesel generators due to a protective relay
      actuating to lock out the bus. The diesels had been declared functional
      and were credited in performance indicators and probabilistic risk
      assessment models since October 2013, when construction was
      completed but testing had not been fully completed. Troubleshooting as a
      result of the failed test found incorrect wiring of a protective relay to be
      the cause. Extent of condition inspections found that the train B bus
      connection was also wired incorrectly, and neither safety related bus
      would have been able to have been powered from the station blackout
      diesel generators. The licensee had intended to perform testing during
      the previous refueling outage, but construction delays caused work to
      extend beyond the outage. Plant conditions for this test necessitated the
      plant be shut down. The inspectors had engaged the licensee concerning
      their testing plan when construction was complete, but the licensee
      concluded that their quality checks were adequate to have a high
      confidence that testing to connect the generators to the safety buses
      would be adequate until plant conditions for the testing were available.
      The inspectors concluded that those quality checks were inadequate,
      although this did not constitute a violation because the diesel generators
      and protective relaying were non-safety equipment and were not credited
      to meet any regulatory requirements. Condition Report 83379.
                                  - 17 -
 
Not all of the validation and verification oversights resulted in plant events or
failures. Some of the items were caught very late in the planning process,
but still impacted regulatory commitments.
    In February of 2014 the licensee commitment to correct long standing
    water hammer conditions in the essential service water system was
    delayed. The 2010 and 2012 Problem Identification and Resolution
    inspections have assessed cited violations regarding long-standing
    essential service water corrosion and water hammer issues not being
    addressed in a timely manner. Wolf Creek responded on the docket and
    committed to fixing the essential service water corrosion and water
    hammer issues by the spring 2014 mid-cycle outage. However, after
    over 3 years of planning, shortly before a modification was to be installed
    to correct the water hammer, it was discovered that the mitigating strategy
    would invalidate the essential service water design basis safety function
    to provide a source of auxiliary feed water during a design basis external
    event that compromises the condensate storage tank. This was
    documented in Condition Reports 53443 and 79619. The licensee
    concluded that there was inadequate contractor oversight during the
    modification development process. A revised modification was tentatively
    rescheduled for the next refueling outage.
    On March 30, 2014, a containment cooler tube bundle failed (small tube
    leaks) as a result of water hammer during the engineered safety features
    actuation system testing. A similar failure occurred when the opposite
    train was tested a few weeks later. While reviewing the cause evaluation,
    the inspectors noted the failure mechanism was due to a combination of
    pitting corrosion and sudden pressure spike during the essential service
    water system water hammer. The ispectors determined that corrective
    actions to address corrosion in carbon steel essential service water piping
    had not addressed the copper-nickel containment cooler tubes. The
    inspectors reviewed the history of containment cooler degradation and
    noted that all 48 of the tube bundles had already been replaced due to
    widespread degradation in the late 1990s, and now the 2nd generation
    like-for-like replacements were beginning to fail. The problem was further
    complicated because non-destructive testing to monitor corrosion was not
    possible because the cooler design and complex cooler geometry
    prevented this. The licensee plans to correct the condition by replacing
    all coolers dueing the next outage, then replacing the original design with
    stainless steel cooler tubes that will allow for eddy current testing.
    Condition Reports 81809 and 82904.
    On November 18, 2011, an NRC Component Design Basis Inspection
    assessed NCV 05000482/2010007-01 for the failure to properly analyze
    the isolation between the safety-related and non-safety related portions of
    the component cooling water system. Portions of the non-safety piping
    leading to the rad waste building are non-seismically qualified, and should
    they fail, could result in a loss of inventory greater than can be
    accommodated by the component cooling water surge tanks. The
    inspector noted that the licensee promptly manually isolated this piping
    and has been working on installing a combination of check valves and
                              - 18 -
 
                      orifices, for the past four years. The planned modification to correct this
                      violation has been delayed a number of times since 2012 because the
                      licensee has found problems with the design. Condition Reports 28237
                      and 85328.
                      The inspectors determined that the licensee was aware of these issues
                      individually, but had not identified the collective trend. The licensee wrote
                      Condition Report 85907 to evaluate and address this trend.
          *  Lack Trending and Prioritization above the Department Level. In reviewing the
            station roll-up reports that record corrective action program activities at the
            station and departmental levels, the inspectors noted that the analytical trending
            ends at the departmental summaries. The station corrective action staff was not
            summarizing analytical trends across divisions, nor were they giving additional
            priority to departmental trends which were having a significant impact on station
            performance. (e.g. design control, procedure quality, etc.)
            The inspectors reviewed additional documentation associated with station
            improvement initiatives and determined that at a station level, senior leadership
            was performing some station level trend analysis and setting station priorities
            based on the available data, but this was being done outside the corrective
            action program, and was not proceduralized and therefore would not continue
            when the improvement initiatives were completed. The licensee has written
            Condition Report 85905 to evaluate and address this issue.
            The inspectors assessment noted improved corrective action trending at the
            department level. The operations department continues to be a station leader in
            this area. The maintenance and engineering departments have made notable
            advancements in the past year to improve the quality of their corrective action
            program work products. The inspectors have also witnessed a significant
            improving trend in the quality, detail, and technical rigor, of apparent cause
            evaluations and root cause analyses performed by station personnel.
  c.  Findings
      No findings were identified.
.3    Annual Follow-up of Selected Issues
  a. Inspection Scope
      The inspectors selected one issues for an in-depth follow-up:
          *  On May 1, 2014, below ground essential service water piping replacement to
            correct long standing corrosion issues.
            The inspectors assessed the licensees problem identification threshold, cause
            analyses, extent of condition reviews and compensatory actions. The inspectors
            reviewed modifications paperwork and observed pipe fitting and welding activities
            in the field. The inspectors verified that the licensee appropriately prioritized the
                                                - 19 -
 
                planned corrective actions and that these actions were adequate to correct the
                condition.
        These activities constitute completion of one annual follow-up sample as defined in
        Inspection Procedure 71152.
  b.  Findings
        No findings were identified.

PLANT STATUS

Wolf Creek began the inspection period with the unit in Mode 5 (cold shutdown) for a planned

mid-cycle outage. On May 8, 2014, the reactor was restarted then promptly shut down due to a

leaking steam generator bowl drain valve inside containment. On May 10, 2014, the reactor

was again restarted and promptly shut down due to a reactor coolant pump oil leak inside

containment. On May 13, 2014, the reactor was restarted successfully, reached 100 percent

power on May 15, 2014, and remained at that power level for the remainder of the inspection

period.

2RS7 Radiological Environmental Monitoring Program (71124.07)

a. Inspection Scope

The inspectors evaluated whether the licensees radiological environmental monitoring

program quantified the impact of radioactive effluent releases to the environment and

sufficiently validated the integrity of the radioactive gaseous and liquid effluent release

program. The inspectors verified that the radiological environmental monitoring program

was implemented consistent with the licensees technical specifications and offsite dose

calculation manual, and that the radioactive effluent release program met the design

objective in Appendix I to 10 CFR Part 50. The inspectors verified that the licensees

radiological environmental monitoring program monitored non-effluent exposure

pathways, was based on sound principles and assumptions, and validated that doses to

members of the public were within regulatory dose limits. The inspectors reviewed or

observed the following items:

  • Selected air sampling and dosimeter monitoring stations
  • Collection and preparation of environmental samples
  • Operability, calibration, and maintenance of meteorological instruments
  • Selected events documented in the annual environmental monitoring report

which involved a missed sample, inoperable sampler, lost dosimeter, or

anomalous measurement

  • Selected structures, systems, or components that may contain licensed material

and has a credible mechanism for licensed material to reach ground water

as the result of changes to the land census or sampler station modifications since

the last inspection

  • Calibration and maintenance records for selected air samplers, composite water

samplers, and environmental sample radiation measurement instrumentation

  • Inter-laboratory comparison program results
  • Audits, self-assessments, reports, and corrective action documents related to the

radiological environmental monitoring program since the last inspection

These activities constitute completion of one sample of the radiological environmental

monitoring program as defined in Inspection Procedure 71124.07.

4OA1 Performance Indicator Verification (71151)

.1 Reactor Coolant System Specific Activity (BI01)

a. Inspection Scope

The inspectors reviewed the licensees reactor coolant system chemistry sample

analyses for the period of April 1, 2013, through March 31, 2014, to verify the accuracy

and completeness of the reported data. The inspectors reviewed the surveillance

paperwork for the reactor coolant system sample taken on May 19, 2014. The

inspectors used definitions and guidance contained in Nuclear Energy Institute

Document 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 7,

to determine the accuracy of the reported data.

These activities constituted verification of the reactor coolant system specific activity

performance indicator, as defined in Inspection Procedure 71151.

b. Findings

No findings were identified.

.2 Reactor Coolant System Identified Leakage (BI02)

a. Inspection Scope

The inspectors reviewed the licensees records of reactor coolant system identified

leakage for the period of April 1, 2013 through March 31, 2014 to verify the accuracy and

completeness of the reported data. The inspectors reviewed the performance

of STS BB-006 RCS Water Inventory Balance on May 31, 2014. The inspectors used

definitions and guidance contained in Nuclear Energy Institute Document 99-02,

Regulatory Assessment Performance Indicator Guideline, Revision 7, to determine the

accuracy of the reported data.

These activities constituted verification of the reactor coolant system leakage

performance indicator, as defined in Inspection Procedure 71151.

b. Findings

No findings were identified.

4OA2 Problem Identification and Resolution (71152)

.1 Routine Review

a. Inspection Scope

Throughout the inspection period, the inspectors performed daily reviews of items

entered into the licensees corrective action program and periodically attended the

licensees condition report screening meetings. The inspectors verified that licensee

personnel were identifying problems at an appropriate threshold and entering these

problems into the corrective action program for resolution. The inspectors verified that

- 14 -

the licensee developed and implemented corrective actions commensurate with the

significance of the problems identified. The inspectors also reviewed the licensees

problem identification and resolution activities during the performance of the other

inspection activities documented in this report.

b. Findings

No findings were identified.

.2 Semiannual Trend Review

a. Inspection Scope

To verify that the licensee was taking corrective actions to address identified adverse

trends that might indicate the existence of a more significant safety issue, the inspectors

reviewed corrective action program documentation associated with the following

licensee-identified trends:

  • High backlogs in the design implementation and configuration control process

area

Also, the inspectors identified the following trends that might indicate the existence of a

more significant safety issue, and reviewed the licensees response to them:

  • Inadequate technical verification and validation of temporary and permanent

plant modifications

  • The licensees corrective action program group is not trending data at a station-

wide level (i.e., above the department level), nor are they prioritizing

departmental issues and trends which are significantly affecting overall station

performance

The NRC identified a theme in NRC inspection findings with cross-cutting aspects in

maintaining design margins [H.6] during the 2013 End Of Cycle Assessment. The

inspectors reviewed the licensees response to that trend to verify that the licensee was

taking appropriate actions to address it.

These activities constitute completion of one semiannual trend review sample, as

defined in Inspection Procedure 71152.

b. Observations and Assessments

The inspectors review of the trends identified above produced the following observations

and assessments:

  • Design Control Backlogs. In July of 2013, an industry group assessment of

station performance noted an unusually high number of open design change

packages. The backlog included approximately 1700 change packages, some

open since the early 1990s, including some SSCs with multiple open design

changes. Some change packages had targeted completion dates that were

- 15 -

beyond the expiration date of the plant operating license. Historically, the station

has had challenges with design control, as noted in NRC inspection reports.

The licensee performed an apparent cause evaluation under Condition

Reports 72164, 72166, and 72167 to identify the organizational causes. Among

the licensees conclusions, management oversight of configuration control was

lacking, there was not an awareness of the vulnerability created by incomplete

configuration changes, and there was no single owner of design change products

to ensure configuration management documents are kept up to date. The

licensee took corrective actions to develop a configuration management health

plan to improve the design control program as well as developing a

comprehensive backlog reduction strategy. The inspectors also noted that the

licensee performed an aggregate risk assessment of the backlog to ensure that

items with more significant safety impacts were addressed more quickly. The

inspectors also noted that the backlog reduction program has reduced the

number of open change packages to 400 at the end of June 2014, with a goal of

less than 200 planned by January 2015.

  • Findings with Design Margins Cross Cutting Aspect [H6]. A theme in findings

with cross-cutting aspects in the area of maintaining design margins was

identified during the NRCs 2013 End of Cycle Assessment for Wolf Creek. The

licensee performed an apparent cause evaluation under Condition

Reports 74508 and 78794. The inspectors noted that this trend was related to

the larger problem of backlog management. Because this trend is related to

other improvement efforts, the inspectors noted that the licensee has evaluated

and taken actions related to this theme in the areas of corrective action,

preventive maintenance, and procedure revision backlog reductions under

Condition Reports 62394, 68194, and 78708. Most of the backlog improvement

efforts were making a notable reduction. The inspectors observed that most

backlog reduction efforts remained on target through the mid-cycle 20 outage in

March and April of 2014. Overall outage management and scope control

performance improvement was observed, and as a result, the corrective action

and work order backlogs did not see the growth observed during previous

outages. The licensee has taken corrective actions to establish and validate new

internal performance indicators for the engineering and maintenance

departments. Furthermore the licensee has scheduled actions to track these

new indicators and backlogs to specific goals based on industry standards in the

future.

Also, while completing this trend review, the inspectors identified the following trends

that the licensee had not previously identified. The inspectors also reviewed the

licensees response to these trends:

  • Quality of Plant Modifications. Over the past 2 years, Wolf Creek has been

implementing a large number of modifications. Additional non-safety related

diesel generators and an auxiliary feed water pump were added to improve plant

safety. The plant has also been addressing long standing corrosion and water

hammer issues in the essential service water system by replacing piping above

and below ground. Obsolete analog controllers have been replaced with digital

control systems. However, the inspectors have observed a number of plant

events and equipment failures associated with inadequate technical validation

- 16 -

and verification associated with these modifications.

On May 2, 2013, an unplanned and uncontrolled 11 percent power

increase occurred as a result of operator training deficiencies while

swapping from the full arc to partial arc steam admission shortly after

installing the new Westinghouse Ovation digital turbine controls. It was

subsequently determined that additional functions and flexibilities of the

new digital control system allowed operators to manipulate the plant in

configurations prohibited by the old analog system, and that system

response varied with power level, but this was not recognized and

incorporated into procedures and training. Condition Report 68711,

Non-Cited Violation NCV 05000482/2013003-05.

On May 28, 2013, and again on September 5, 2013, the turbine driven

auxiliary feed water pump control system failed unexpectedly, rendering

the pump incapable of operation. The digital control system positioner

locked up and required replacement. It was later determined that an

additional unused input to the positioner was experiencing noise, and if

the noise came in at a certain point in the digital computer programs

subroutine, the control software would crash. The problem was fixed by

jumpering out the unused input connection and a vendor technical bulletin

was issued to correct vulnerabilities at other nuclear power plants utilizing

the same control system. Condition Reports 69721, 69754, and 73624.

On April 25, 2014, during station blackout diesel generator testing, the

licensee was unable to connect the train A Class 1E 4kV distribution bus

to the station blackout diesel generators due to a protective relay

actuating to lock out the bus. The diesels had been declared functional

and were credited in performance indicators and probabilistic risk

assessment models since October 2013, when construction was

completed but testing had not been fully completed. Troubleshooting as a

result of the failed test found incorrect wiring of a protective relay to be

the cause. Extent of condition inspections found that the train B bus

connection was also wired incorrectly, and neither safety related bus

would have been able to have been powered from the station blackout

diesel generators. The licensee had intended to perform testing during

the previous refueling outage, but construction delays caused work to

extend beyond the outage. Plant conditions for this test necessitated the

plant be shut down. The inspectors had engaged the licensee concerning

their testing plan when construction was complete, but the licensee

concluded that their quality checks were adequate to have a high

confidence that testing to connect the generators to the safety buses

would be adequate until plant conditions for the testing were available.

The inspectors concluded that those quality checks were inadequate,

although this did not constitute a violation because the diesel generators

and protective relaying were non-safety equipment and were not credited

to meet any regulatory requirements. Condition Report 83379.

- 17 -

Not all of the validation and verification oversights resulted in plant events or

failures. Some of the items were caught very late in the planning process,

but still impacted regulatory commitments.

In February of 2014 the licensee commitment to correct long standing

water hammer conditions in the essential service water system was

delayed. The 2010 and 2012 Problem Identification and Resolution

inspections have assessed cited violations regarding long-standing

essential service water corrosion and water hammer issues not being

addressed in a timely manner. Wolf Creek responded on the docket and

committed to fixing the essential service water corrosion and water

hammer issues by the spring 2014 mid-cycle outage. However, after

over 3 years of planning, shortly before a modification was to be installed

to correct the water hammer, it was discovered that the mitigating strategy

would invalidate the essential service water design basis safety function

to provide a source of auxiliary feed water during a design basis external

event that compromises the condensate storage tank. This was

documented in Condition Reports 53443 and 79619. The licensee

concluded that there was inadequate contractor oversight during the

modification development process. A revised modification was tentatively

rescheduled for the next refueling outage.

On March 30, 2014, a containment cooler tube bundle failed (small tube

leaks) as a result of water hammer during the engineered safety features

actuation system testing. A similar failure occurred when the opposite

train was tested a few weeks later. While reviewing the cause evaluation,

the inspectors noted the failure mechanism was due to a combination of

pitting corrosion and sudden pressure spike during the essential service

water system water hammer. The ispectors determined that corrective

actions to address corrosion in carbon steel essential service water piping

had not addressed the copper-nickel containment cooler tubes. The

inspectors reviewed the history of containment cooler degradation and

noted that all 48 of the tube bundles had already been replaced due to

widespread degradation in the late 1990s, and now the 2nd generation

like-for-like replacements were beginning to fail. The problem was further

complicated because non-destructive testing to monitor corrosion was not

possible because the cooler design and complex cooler geometry

prevented this. The licensee plans to correct the condition by replacing

all coolers dueing the next outage, then replacing the original design with

stainless steel cooler tubes that will allow for eddy current testing.

Condition Reports 81809 and 82904.

On November 18, 2011, an NRC Component Design Basis Inspection

assessed NCV 05000482/2010007-01 for the failure to properly analyze

the isolation between the safety-related and non-safety related portions of

the component cooling water system. Portions of the non-safety piping

leading to the rad waste building are non-seismically qualified, and should

they fail, could result in a loss of inventory greater than can be

accommodated by the component cooling water surge tanks. The

inspector noted that the licensee promptly manually isolated this piping

and has been working on installing a combination of check valves and

- 18 -

orifices, for the past four years. The planned modification to correct this

violation has been delayed a number of times since 2012 because the

licensee has found problems with the design. Condition Reports 28237

and 85328.

The inspectors determined that the licensee was aware of these issues

individually, but had not identified the collective trend. The licensee wrote

Condition Report 85907 to evaluate and address this trend.

  • Lack Trending and Prioritization above the Department Level. In reviewing the

station roll-up reports that record corrective action program activities at the

station and departmental levels, the inspectors noted that the analytical trending

ends at the departmental summaries. The station corrective action staff was not

summarizing analytical trends across divisions, nor were they giving additional

priority to departmental trends which were having a significant impact on station

performance. (e.g. design control, procedure quality, etc.)

The inspectors reviewed additional documentation associated with station

improvement initiatives and determined that at a station level, senior leadership

was performing some station level trend analysis and setting station priorities

based on the available data, but this was being done outside the corrective

action program, and was not proceduralized and therefore would not continue

when the improvement initiatives were completed. The licensee has written

Condition Report 85905 to evaluate and address this issue.

The inspectors assessment noted improved corrective action trending at the

department level. The operations department continues to be a station leader in

this area. The maintenance and engineering departments have made notable

advancements in the past year to improve the quality of their corrective action

program work products. The inspectors have also witnessed a significant

improving trend in the quality, detail, and technical rigor, of apparent cause

evaluations and root cause analyses performed by station personnel.

c. Findings

No findings were identified.

.3 Annual Follow-up of Selected Issues

a. Inspection Scope

The inspectors selected one issues for an in-depth follow-up:

  • On May 1, 2014, below ground essential service water piping replacement to

correct long standing corrosion issues.

The inspectors assessed the licensees problem identification threshold, cause

analyses, extent of condition reviews and compensatory actions. The inspectors

reviewed modifications paperwork and observed pipe fitting and welding activities

in the field. The inspectors verified that the licensee appropriately prioritized the

- 19 -

planned corrective actions and that these actions were adequate to correct the

condition.

These activities constitute completion of one annual follow-up sample as defined in

Inspection Procedure 71152.

b. Findings

No findings were identified.
