==Dear Mr. Heflin:==
SUBJECT: WOLF CREEK GENERATING STATION - NRC BASELINE INSPECTION REPORT 05000482/2013502, PRELIMINARY WHITE FINDING Dear Mr. Heflin:
This letter refers to the in-office and onsite inspections conducted September 3, 2013, through March 4, 2014, for the Wolf Creek Generating Station. The inspection was a baseline evaluation of your emergency preparedness program through observation of emergency response organization performance during the November 5, 2013, biennial exercise. The enclosed report presents the results of this inspection. The inspectors discussed the preliminary inspection findings with you and your staff at the conclusion of the on-site portion of the inspection. Additional telephone discussions occurred on September 30, 2013, and January 27, February 10, and February 20, 2014. A final exit briefing was conducted with you and your staff on March 4, 2014. This inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions in your license.

The report covered an announced baseline inspection by region-based and resident inspectors. 
One apparent violation was identified whose significance has not been determined.  The
significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process."  The cross-cutting aspect is determined using Inspection Manual Chapter 0310, "Components Within the Cross
Cutting Areas."  The NRC's program for overseeing the safe operation of commercial nuclear
power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
A. NRC-Identified Findings and Self-Revealing Findings    Cornerstone:  Emergency Preparedness
* TBD.  An apparent violation of 10 CFR 50.54(q)(2) was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency between September 2012 and November 2013, in accordance with the requirements of 10 CFR 50.47(b)(9). 
During an exercise conducted on November 13, 2012, the licensee identified that
the Electronic Dose Calculation Program did not accurately calculate the
consequences of a radiological release through the main vent stack with the
effluent monitor in accident mode.  The inaccurate calculation was corrected on February 25, 2014.  The inspectors determined the failure to maintain a dose assessment process
capable of providing a technically adequate estimate of offsite dose was a
performance deficiency within the licensee's control.  This finding is more than minor because it was associated with the emergency response organization performance and the Facilities and Equipment cornerstone attributes.  This
finding was evaluated using the Emergency Preparedness Significance
Determination Process and was preliminarily determined to be of low to
moderate safety significance (White) because it was a degraded risk significant
planning standard function.  The planning standard function was degraded because between September 13, 2012, and November 8, 2013, some calculations used to assess the offsite consequences of a radiological release
were inaccurate.  This issue has been entered into the licensee's corrective
action system as Condition Report 2013-0076247 (Section 1EP5).   
  - 3 -  REPORT DETAILS  1. REACTOR SAFETY Cornerstone:  Emergency Preparedness 1EP1 Exercise Evaluation (71114.01) a. Inspection Scope The inspectors observed the biennial emergency preparedness exercise conducted, November 5, 2013, to determine if the exercise acceptably tested major elements of the
emergency plan and provided opportunities to demonstrate key emergency response organization skills.  The scenario simulated the following to demonstrate the licensee personnel's capability to implement their emergency plan:
* An earthquake with a strong aftershock * An automatic plant trip with control rods that fail to insert * A reactor coolant system leak inside containment that increases over time * Failures of primary and auxiliary feed pumps to the steam generators * A fire in a charcoal filter that causes the radiological release to be unfiltered * A failure of the containment purge system that creates a monitored release to the environment 
The inspectors evaluated exercise performance by focusing on the risk significant activities of event classification, offsite notification, recognition of offsite dose consequences, and development of protective action recommendations, in the Control
Room Simulator and the following dedicated emergency response facilities:
* Technical Support Center * Operations Support Center * Emergency Operations Facility  The inspectors also assessed recognition of, and response to, abnormal and emergency plant conditions, the transfer of decision making authority and emergency function
responsibilities between facilities, onsite and offsite communications, protection of emergency workers, emergency repair evaluation and capability, and the overall implementation of the emergency plan to protect public health and safety and the
environment.  The inspectors reviewed the facility emergency plan, the emergency plan
implementing procedures associated with operation of the emergency response
facilities, the procedures for the performance of associated emergency functions, and
other documents as listed in the attachment to this report.  The inspectors compared the observed exercise performance with the requirements in the facility emergency plan; 10 CFR 50.47(b); 10 CFR Part 50, Appendix E; and with the
guidance in the emergency plan implementing procedures and other federal guidance.
The inspectors attended the post-exercise critiques in each emergency response facility to evaluate the initial licensee self-assessment of exercise performance.  The inspectors
also attended a subsequent formal presentation of critique items to plant management.
The specific documents reviewed during this inspection are listed in the attachment. 
 
  - 4 -  These activities constitute completion of one sample as defined in Inspection Procedure 71114.01-05.  b. Findings No findings were identified. 
1EP5 Maintenance of Emergency Preparedness (71114.05) a. Inspection Scope The inspectors performed an in-office and on-site review of the licensee's response to Condition Report 59832, dated November 13, 2013, which documented a potential
inaccuracy in the Emergency Dose Assessment Program identified during an exercise conducted November 13, 2012.  b. Findings Introduction.  An apparent violation was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency as required by 10 CFR 50.54(q)(2) and 10 CFR 50.47(b)(9).  Specifically, the
licensee's dose assessment model incorrectly calculated the concentration of iodine and
particulate radioactive material released through the main vent stack when the effluent
monitor was in accident mode.  This resulted in inaccurate dose assessments between September 13, 2012, and November 8, 2013. 
Description.  A deficiency was identified that degraded the licensee's ability to accurately assess the offsite dose consequences of a radiological release.  The NRC determined
that, on November 13, 2012, the licensee had identified that its Electronic Dose
Calculation Program (EDCP, radiological assessment software) was potentially inaccurate, and as of November 5, 2013, had not evaluated or corrected the inaccuracy. 
The NRC observed that the licensee dose assessor participating in the November 5, 2013, emergency preparedness exercise was knowledgeable about an inaccuracy in the Electronic Dose Calculation Program (licensee's radiological assessment software).  The inspectors subsequently reviewed Condition Report 00059832, "E-Plan Drill, Potential Incorrect EDCP Dose Assessments," dated November 13, 2012, which documented a
potential inaccuracy in EDCP calculations using the main vent stack radiation monitor
that was identified during an exercise conducted November 13, 2012.
In its normal operating mode, the main vent stack effluent radiation monitor reports separate release rates for total noble gasses, radioactive Iodine, and radioactive particulates.  In 'accident mode' the iodine and particulate release rates are not
measured because the detectors are manually isolated.  The inspectors determined that
Control Room personnel place this monitor in accident mode when the noble gas
channel reaches a value of 3530 microCuries per second (µCi/s) and goes into Alert Alarm.  When the main vent stack radiation monitor is in accident mode, EDCP compensates by calculating assumed iodine and particulate release rates, using a noble
gas to iodine ratio.  A default ratio of 10 is assumed (e.g., the iodine release rate is set to
10 percent of the measured noble gas release rate).  Users identified that during the
November 13, 2012, exercise; EDCP did not appear to be applying the expected noble gas to iodine ratio when the vent stack radiation monitor was in accident mode.  On 
  - 5 -  November 7, 2013, the licensee confirmed that EDCP was not correctly applying the default noble gas to iodine ratio when the monitor was in accident mode, resulting in an overestimate of the concentration of iodine and particulates by a factor of 10, and an overestimate of the Thyroid Committed Dose Equivalent.  The licensee put interim
compensatory measures in place on November 8, 2013, to ensure that inaccurate
information was not used in the determining protective action recommendations; the
licensee directed that dose assessment be considered as 'not available' when a radiological release was through the main stack with the effluent radiation monitor in accident mode. The licensee determined this problem existed in EDCP, Version 4.7, implemented on September 13, 2012, and in EDCP, Version 4.8, implemented on
October 28, 2013.
EDCP is a licensee-written program, maintained by the licensee's Information Systems Department.  The licensee initiated Service Request 126710 to the Information Systems Department on January 10, 2013, to investigate the apparent inaccuracies in EDCP
calculations and, if confirmed, to correct the problem.  The licensee reported on
November 7, 2013, that the Information Systems Department had not performed any work on Service Request 126710, and that an analyst and due date were not currently assigned.  The licensee corrected the inaccurate calculation in EDCP, Version 4.9, implemented on February 25, 2014.
The inspectors determined that Chemistry Technicians were trained as Dose Assessors
and Chemists were trained as Radiological Assessment Coordinators.  Training for these individuals was conducted during routinely scheduled chemistry department training sessions.  The licensee informed the chemistry technicians and chemists about the apparent inaccuracy in EDCP calculations during training cycles 13-Q2, April 15 through
May 21, 2013, and 13-Q3, July 8 through August 15, 2013.  Analysis.  The inspectors determined that the failure to maintain a dose assessment process capable of providing a technically adequate estimate of offsite dose is a performance deficiency within the licensee's control.  This finding is more than minor
because it affected the licensee's ability to implement adequate measures to protect the health and safety of the public.  The finding also affected the facilities and equipment
and emergency response organizations performance cornerstone attributes.  The finding was associated with a violation of NRC requirements.  This finding was evaluated using IMC 0609, Appendix B, "Emergency Preparedness Significance Determination Process," and was evaluated in accordance with Attachment 2.  The finding was preliminarily
determined to be of low to moderate safety significance (White) because it was a failure
to comply with NRC requirements and was a degraded risk significant planning standard function.  The planning standard function was degraded because methods to assess the offsite consequences of a radiological release via the main vent stack pathway were inaccurate between September 13, 2012, and November 8, 2013.  However, these
errors did not affect other calculations performed by the EDCP.  This issue has been
entered into the licensee's corrective action system as Condition Report 2013-0076247. 
A cross-cutting aspect of evaluation in the problem identification and resolution area was
assigned to this finding because the finding is representative of current performance and the licensee failed to promptly evaluate whether a problem existed with the Electronic Dose Calculation Program after an issue was raised following the November 13, 2012,
EP exercise.  The licensee failed to verify the existence of a safety-significant problem and subsequently, failed to resolve the problem within a timeframe appropriate to its
safety significance [P.2].   
  - 6 -  Enforcement.  Title 10 of the Code of Federal Regulations (CFR), Part 50.54(q)(2), requires, in part, that the holder of a nuclear power reactor operating license shall follow and maintain the effectiveness of an  emergency plan that meets the planning standards of 10 CFR 50.47(b).  Title 10 CFR Part 50.47(b)(9) requires, in part, that the onsite and
offsite emergency response plans must use adequate methods for assessing and
monitoring actual or potential offsite consequences of a radiological emergency condition. 
Contrary to the above, between September 13, 2012, and November 8, 2013, the licensee failed to maintain an emergency plan that used adequate methods for
assessing and monitoring the actual or potential offsite consequences of a radiological
emergency condition.  Specifically, a calculational error in the licensee's Electronic Dose
Calculation Program resulted in inaccurate offsite doses for the main vent stack pathway when the effluent radiation monitor was in the accident mode: AV 05000482/2013502-01 (Failure to Maintain Accurate Methods for Dose Assessment). 
1EP8 Exercise Evaluation (71114.08) a. Inspection Scope The licensee submitted the preliminary scenario for the 2013 biennial emergency preparedness exercise on September 3, 2013, in accordance with the requirements of
Appendix E to 10 CFR 50, Part IV.F(2)(b).  The inspectors performed an in-office review
of the preliminary exercise scenario to determine whether the scenario would acceptably test the major elements of the licensee's emergency plan and provided opportunities to demonstrate the key emergency response organization skills.  b. Findings No findings were identified. 
4. OTHER ACTIVITIES 4OA1 Performance Indicator Verification (71151) .13 Drill/Exercise Performance (EP01) a. Inspection Scope The inspectors sampled licensee submittals for the Drill and Exercise Performance, performance indicator for the period July 2012 through September 2013.  The definitions
and guidance of Nuclear Energy Institute Document 99-02, "Regulatory Assessment
Performance Indicator Guideline," Revision 6, were used to determine the accuracy of
the performance indicator data reported to the NRC.  The inspectors reviewed the licensee's records associated with the performance indicator to verify that the licensee accurately reported the indicator in accordance with relevant procedures and the
Nuclear Energy Institute guidance.  Specifically, the inspectors reviewed licensee
records and processes including procedural guidance on assessing opportunities for the
performance indicator; assessments of performance indicator opportunities during predesignated control room simulator training sessions, performance during the 2013 biennial exercise, and performance during other drills.  The specific documents reviewed

The report covered an announced baseline inspection by region-based and resident inspectors.
One apparent violation was identified whose significance has not been determined. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process."  The cross-cutting aspect is determined using Inspection Manual Chapter 0310, "Components Within the Cross Cutting Areas."  The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
===A. NRC-Identified Findings and Self-Revealing Findings===
===Cornerstone: Emergency Preparedness===
* TBD. An apparent violation of 10 CFR 50.54(q)(2) was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency between September 2012 and November 2013, in accordance with the requirements of 10 CFR 50.47(b)(9).
During an exercise conducted on November 13, 2012, the licensee identified that the Electronic Dose Calculation Program did not accurately calculate the consequences of a radiological release through the main vent stack with the effluent monitor in accident mode. The inaccurate calculation was corrected on February 25, 2014. The inspectors determined the failure to maintain a dose assessment process capable of providing a technically adequate estimate of offsite dose was a performance deficiency within the licensee's control. This finding is more than minor because it was associated with the emergency response organization performance and the Facilities and Equipment cornerstone attributes. This finding was evaluated using the Emergency Preparedness Significance Determination Process and was preliminarily determined to be of low to moderate safety significance (White) because it was a degraded risk significant planning standard function. The planning standard function was degraded because between September 13, 2012, and November 8, 2013, some calculations used to assess the offsite consequences of a radiological release were inaccurate. This issue has been entered into the licensee's corrective action system as Condition Report 2013-0076247 (Section 1EP5).

====a. Inspection Scope====
The inspectors observed the biennial emergency preparedness exercise conducted, November 5, 2013, to determine if the exercise acceptably tested major elements of the emergency plan and provided opportunities to demonstrate key emergency response organization skills. The scenario simulated the following to demonstrate the licensee personnel's capability to implement their emergency plan:
* An earthquake with a strong aftershock
* An automatic plant trip with control rods that fail to insert
* A reactor coolant system leak inside containment that increases over time
* Failures of primary and auxiliary feed pumps to the steam generators
* A fire in a charcoal filter that causes the radiological release to be unfiltered
* A failure of the containment purge system that creates a monitored release to the environment The inspectors evaluated exercise performance by focusing on the risk significant activities of event classification, offsite notification, recognition of offsite dose consequences, and development of protective action recommendations, in the Control Room Simulator and the following dedicated emergency response facilities:
* Technical Support Center
* Operations Support Center
* Emergency Operations Facility  The inspectors also assessed recognition of, and response to, abnormal and emergency plant conditions, the transfer of decision making authority and emergency function responsibilities between facilities, onsite and offsite communications, protection of emergency workers, emergency repair evaluation and capability, and the overall implementation of the emergency plan to protect public health and safety and the environment. The inspectors reviewed the facility emergency plan, the emergency plan implementing procedures associated with operation of the emergency response facilities, the procedures for the performance of associated emergency functions, and other documents as listed in the attachment to this report. The inspectors compared the observed exercise performance with the requirements in the facility emergency plan; 10 CFR 50.47(b); 10 CFR Part 50, Appendix E; and with the guidance in the emergency plan implementing procedures and other federal guidance.
The inspectors attended the post-exercise critiques in each emergency response facility to evaluate the initial licensee self-assessment of exercise performance. The inspectors also attended a subsequent formal presentation of critique items to plant management.
The specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one sample as defined in Inspection Procedure 71114.01-05.

==1EP5 Maintenance of Emergency Preparedness==
{{IP sample|IP=IP 71114.05}}
====a. Inspection Scope====
The inspectors performed an in-office and on-site review of the licensee's response to Condition Report 59832, dated November 13, 2013, which documented a potential inaccuracy in the Emergency Dose Assessment Program identified during an exercise conducted November 13, 2012.
====b. Findings====
=====Introduction.=====
An apparent violation was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency as required by 10 CFR 50.54(q)(2) and 10 CFR 50.47(b)(9). Specifically, the licensee's dose assessment model incorrectly calculated the concentration of iodine and particulate radioactive material released through the main vent stack when the effluent monitor was in accident mode. This resulted in inaccurate dose assessments between September 13, 2012, and November 8, 2013.
=====Description.=====
A deficiency was identified that degraded the licensee's ability to accurately assess the offsite dose consequences of a radiological release. The NRC determined that, on November 13, 2012, the licensee had identified that its Electronic Dose Calculation Program (EDCP, radiological assessment software) was potentially inaccurate, and as of November 5, 2013, had not evaluated or corrected the inaccuracy.
The NRC observed that the licensee dose assessor participating in the November 5, 2013, emergency preparedness exercise was knowledgeable about an inaccuracy in the Electronic Dose Calculation Program (licensee's radiological assessment software). The inspectors subsequently reviewed Condition Report 00059832, "E-Plan Drill, Potential Incorrect EDCP Dose Assessments," dated November 13, 2012, which documented a potential inaccuracy in EDCP calculations using the main vent stack radiation monitor that was identified during an exercise conducted November 13, 2012.
In its normal operating mode, the main vent stack effluent radiation monitor reports separate release rates for total noble gasses, radioactive Iodine, and radioactive particulates. In 'accident mode' the iodine and particulate release rates are not measured because the detectors are manually isolated. The inspectors determined that Control Room personnel place this monitor in accident mode when the noble gas channel reaches a value of 3530 microCuries per second (µCi/s) and goes into Alert Alarm. When the main vent stack radiation monitor is in accident mode, EDCP compensates by calculating assumed iodine and particulate release rates, using a noble gas to iodine ratio. A default ratio of 10 is assumed (e.g., the iodine release rate is set to 10 percent of the measured noble gas release rate). Users identified that during the November 13, 2012, exercise; EDCP did not appear to be applying the expected noble gas to iodine ratio when the vent stack radiation monitor was in accident mode. On November 7, 2013, the licensee confirmed that EDCP was not correctly applying the default noble gas to iodine ratio when the monitor was in accident mode, resulting in an overestimate of the concentration of iodine and particulates by a factor of 10, and an overestimate of the Thyroid Committed Dose Equivalent. The licensee put interim compensatory measures in place on November 8, 2013, to ensure that inaccurate information was not used in the determining protective action recommendations; the licensee directed that dose assessment be considered as 'not available' when a radiological release was through the main stack with the effluent radiation monitor in accident mode. The licensee determined this problem existed in EDCP, Version 4.7, implemented on September 13, 2012, and in EDCP, Version 4.8, implemented on October 28, 2013.
EDCP is a licensee-written program, maintained by the licensee's Information Systems Department. The licensee initiated Service Request 126710 to the Information Systems Department on January 10, 2013, to investigate the apparent inaccuracies in EDCP calculations and, if confirmed, to correct the problem. The licensee reported on November 7, 2013, that the Information Systems Department had not performed any work on Service Request 126710, and that an analyst and due date were not currently assigned. The licensee corrected the inaccurate calculation in EDCP, Version 4.9, implemented on February 25, 2014.
The inspectors determined that Chemistry Technicians were trained as Dose Assessors and Chemists were trained as Radiological Assessment Coordinators. Training for these individuals was conducted during routinely scheduled chemistry department training sessions. The licensee informed the chemistry technicians and chemists about the apparent inaccuracy in EDCP calculations during training cycles 13-Q2, April 15 through May 21, 2013, and 13-Q3, July 8 through August 15, 2013.
=====Analysis.=====
The inspectors determined that the failure to maintain a dose assessment process capable of providing a technically adequate estimate of offsite dose is a performance deficiency within the licensee's control. This finding is more than minor because it affected the licensee's ability to implement adequate measures to protect the health and safety of the public. The finding also affected the facilities and equipment and emergency response organizations performance cornerstone attributes. The finding was associated with a violation of NRC requirements. This finding was evaluated using IMC 0609, Appendix B, "Emergency Preparedness Significance Determination Process," and was evaluated in accordance with Attachment 2. The finding was preliminarily determined to be of low to moderate safety significance (White) because it was a failure to comply with NRC requirements and was a degraded risk significant planning standard function. The planning standard function was degraded because methods to assess the offsite consequences of a radiological release via the main vent stack pathway were inaccurate between September 13, 2012, and November 8, 2013. However, these errors did not affect other calculations performed by the EDCP. This issue has been entered into the licensee's corrective action system as Condition Report 2013-0076247.
A cross-cutting aspect of evaluation in the problem identification and resolution area was assigned to this finding because the finding is representative of current performance and the licensee failed to promptly evaluate whether a problem existed with the Electronic Dose Calculation Program after an issue was raised following the November 13, 2012, EP exercise. The licensee failed to verify the existence of a safety-significant problem and subsequently, failed to resolve the problem within a timeframe appropriate to its safety significance [P.2].
=====Enforcement.=====
Title 10 of the Code of Federal Regulations (CFR), Part 50.54(q)(2), requires, in part, that the holder of a nuclear power reactor operating license shall follow and maintain the effectiveness of an  emergency plan that meets the planning standards of 10 CFR 50.47(b). Title 10 CFR Part 50.47(b)(9) requires, in part, that the onsite and offsite emergency response plans must use adequate methods for assessing and monitoring actual or potential offsite consequences of a radiological emergency condition.
Contrary to the above, between September 13, 2012, and November 8, 2013, the licensee failed to maintain an emergency plan that used adequate methods for assessing and monitoring the actual or potential offsite consequences of a radiological emergency condition. Specifically, a calculational error in the licensee's Electronic Dose Calculation Program resulted in inaccurate offsite doses for the main vent stack pathway when the effluent radiation monitor was in the accident mode: AV 05000482/2013502-01 (Failure to Maintain Accurate Methods for Dose Assessment).

SUBJECT: WOLF CREEK GENERATING STATION - NRC BASELINE INSPECTION REPORT 05000482/2013502, PRELIMINARY WHITE FINDING Dear Mr. Heflin:

This letter refers to the in-office and onsite inspections conducted September 3, 2013, through

March 4, 2014, for the Wolf Creek Generating Station. The inspection was a baseline

evaluation of your emergency preparedness program through observation of emergency

response organization performance during the November 5, 2013, biennial exercise. The enclosed report presents the results of this inspection. The inspectors discussed the preliminary inspection findings with you and your staff at the conclusion of the on-site portion of

the inspection. Additional telephone discussions occurred on September 30, 2013, and

January 27, February 10, and February 20, 2014. A final exit briefing was conducted with you

and your staff on March 4, 2014. This inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions in your license.

Within these areas, the inspection consisted of an examination of selected procedures and

representative records, observations of emergency preparedness activities, and interviews with

personnel. This inspection identified a finding that has preliminarily been determined to be a White finding

with low to moderate safety significance that may require additional NRC inspection. The

finding is associated with a failure to maintain adequate methods for assessing the potential

consequences of a radiological emergency condition in accordance with the requirements of 10 CFR 50.47(b)(9). This deficiency was corrected on February 25, 2014. This finding is also an apparent violation of NRC requirements and is being considered for escalated

enforcement action in accordance with the Enforcement Policy, which can be found on the

NRC's Web site at http://www.nrc.gov/about-nrc/regulatory/ enforcement/enforce-pol.html.

The preliminary low to moderate safety significance (White) finding was assessed based on the best available information, using the Emergency Preparedness Significance Determination Process (SDP) and the NRC Enforcement Policy. The basis for the NRC's preliminary

significance determination is described in the enclosed report. The final resolution of this finding

will be conveyed in separate correspondence. UNITED STATES NUCLEAR REGULATORY COMMISSION REGION IV 1600 E. LAMAR BLVD. ARLINGTON, TX 76011-4511

A. Heflin - 2 -

In accordance with NRC Inspection Manual Chapter (IMC) 0609, we intend to complete our evaluation of the White finding using the best available information, and issue our final determination of safety significance within 90 days of the date of this letter. The significance

determination process encourages an open dialogue between the NRC staff and the licensee;

however, the dialogue should not impact the timeliness of the staff's final determination. Before

we make a final decision on this matter, we are providing you with an opportunity to attend a

Regulatory Conference where you can present to the NRC your perspective on the facts and assumptions the NRC used to arrive at the finding and assess its significance, or submit your position on the finding to the NRC in writing.

If you request a Regulatory Conference, it should be held within 30 days of the receipt of this

letter and we encourage you to submit supporting documentation at least one week prior to the Conference in an effort to make the Conference more efficient and effective. The focus of the Regulatory Conference is to discuss the significance of the finding and not necessarily what the

root cause is or corrective action(s) associated with the finding. If a Conference is held, it will be

open for public observation and a public meeting notice and press release will be issued to

announce the conference. If you decide to submit only a written response, such submittal should be sent to the NRC within 30 days of your receipt of this letter. If you decline to request a Conference or to submit a written response, you relinquish your right to appeal the final SDP determination, in that by not doing either, you fail to meet the appeal requirements stated in the Prerequisite and Limitation Sections of Attachment 2 of IMC 0609.

Please contact Mr. Mark Haire, Chief, Plant Support Branch 1, at 817-200-1527, within 10 days from the issue date of this letter to notify the NRC of your intentions. If we have not heard from you within 10 days, we will continue with our significance determination and enforcement

decision. Since the NRC has not made a final determination in these matters, no Notice of

Violation is being issued for these inspection findings at this time. In addition, please be

advised that the number and characterization of the apparent violation may change as a result of further NRC review.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice and Procedure," a copy of

this letter, its enclosures, and your response, if you choose to provide one, will be made

available electronically for public inspection in the NRC Public Document Room or from the NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy or proprietary information so that it can be made available to the Public without redaction.

IR 05000482/2013502; 09/03/2013 - 03/04/2014; Wolf Creek Generating Station, Regional Report; Emergency Plan Biennial Exercise, 71114.01, 71114.05

The report covered an announced baseline inspection by region-based and resident inspectors.

One apparent violation was identified whose significance has not been determined. The

significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process." The cross-cutting aspect is determined using Inspection Manual Chapter 0310, "Components Within the Cross

Cutting Areas." The NRC's program for overseeing the safe operation of commercial nuclear

power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.

A. NRC-Identified Findings and Self-Revealing Findings Cornerstone: Emergency Preparedness

  • TBD. An apparent violation of 10 CFR 50.54(q)(2) was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency between September 2012 and November 2013, in accordance with the requirements of 10 CFR 50.47(b)(9).

During an exercise conducted on November 13, 2012, the licensee identified that

the Electronic Dose Calculation Program did not accurately calculate the

consequences of a radiological release through the main vent stack with the

effluent monitor in accident mode. The inaccurate calculation was corrected on February 25, 2014. The inspectors determined the failure to maintain a dose assessment process

capable of providing a technically adequate estimate of offsite dose was a

performance deficiency within the licensee's control. This finding is more than minor because it was associated with the emergency response organization performance and the Facilities and Equipment cornerstone attributes. This

finding was evaluated using the Emergency Preparedness Significance

Determination Process and was preliminarily determined to be of low to

moderate safety significance (White) because it was a degraded risk significant

planning standard function. The planning standard function was degraded because between September 13, 2012, and November 8, 2013, some calculations used to assess the offsite consequences of a radiological release

were inaccurate. This issue has been entered into the licensee's corrective

action system as Condition Report 2013-0076247 (Section 1EP5).

- 3 - REPORT DETAILS 1. REACTOR SAFETY Cornerstone: Emergency Preparedness 1EP1 Exercise Evaluation (71114.01) a. Inspection Scope The inspectors observed the biennial emergency preparedness exercise conducted, November 5, 2013, to determine if the exercise acceptably tested major elements of the

emergency plan and provided opportunities to demonstrate key emergency response organization skills. The scenario simulated the following to demonstrate the licensee personnel's capability to implement their emergency plan:

  • An earthquake with a strong aftershock * An automatic plant trip with control rods that fail to insert * A reactor coolant system leak inside containment that increases over time * Failures of primary and auxiliary feed pumps to the steam generators * A fire in a charcoal filter that causes the radiological release to be unfiltered * A failure of the containment purge system that creates a monitored release to the environment

The inspectors evaluated exercise performance by focusing on the risk significant activities of event classification, offsite notification, recognition of offsite dose consequences, and development of protective action recommendations, in the Control

Room Simulator and the following dedicated emergency response facilities:

  • Technical Support Center * Operations Support Center * Emergency Operations Facility The inspectors also assessed recognition of, and response to, abnormal and emergency plant conditions, the transfer of decision making authority and emergency function

responsibilities between facilities, onsite and offsite communications, protection of emergency workers, emergency repair evaluation and capability, and the overall implementation of the emergency plan to protect public health and safety and the

environment. The inspectors reviewed the facility emergency plan, the emergency plan

implementing procedures associated with operation of the emergency response

facilities, the procedures for the performance of associated emergency functions, and

other documents as listed in the attachment to this report. The inspectors compared the observed exercise performance with the requirements in the facility emergency plan; 10 CFR 50.47(b); 10 CFR Part 50, Appendix E; and with the

guidance in the emergency plan implementing procedures and other federal guidance.

The inspectors attended the post-exercise critiques in each emergency response facility to evaluate the initial licensee self-assessment of exercise performance. The inspectors

also attended a subsequent formal presentation of critique items to plant management.

The specific documents reviewed during this inspection are listed in the attachment.

- 4 - These activities constitute completion of one sample as defined in Inspection Procedure 71114.01-05. b. Findings No findings were identified.

1EP5 Maintenance of Emergency Preparedness (71114.05) a. Inspection Scope The inspectors performed an in-office and on-site review of the licensee's response to Condition Report 59832, dated November 13, 2013, which documented a potential

inaccuracy in the Emergency Dose Assessment Program identified during an exercise conducted November 13, 2012. b. Findings Introduction. An apparent violation was identified involving the failure to maintain adequate methods for assessing the actual or potential consequences of a radiological emergency as required by 10 CFR 50.54(q)(2) and 10 CFR 50.47(b)(9). Specifically, the

licensee's dose assessment model incorrectly calculated the concentration of iodine and

particulate radioactive material released through the main vent stack when the effluent

monitor was in accident mode. This resulted in inaccurate dose assessments between September 13, 2012, and November 8, 2013.

Description. A deficiency was identified that degraded the licensee's ability to accurately assess the offsite dose consequences of a radiological release. The NRC determined

that, on November 13, 2012, the licensee had identified that its Electronic Dose

Calculation Program (EDCP, radiological assessment software) was potentially inaccurate, and as of November 5, 2013, had not evaluated or corrected the inaccuracy.

The NRC observed that the licensee dose assessor participating in the November 5, 2013, emergency preparedness exercise was knowledgeable about an inaccuracy in the Electronic Dose Calculation Program (licensee's radiological assessment software). The inspectors subsequently reviewed Condition Report 00059832, "E-Plan Drill, Potential Incorrect EDCP Dose Assessments," dated November 13, 2012, which documented a

potential inaccuracy in EDCP calculations using the main vent stack radiation monitor

that was identified during an exercise conducted November 13, 2012.

In its normal operating mode, the main vent stack effluent radiation monitor reports separate release rates for total noble gasses, radioactive Iodine, and radioactive particulates. In 'accident mode' the iodine and particulate release rates are not

measured because the detectors are manually isolated. The inspectors determined that

Control Room personnel place this monitor in accident mode when the noble gas

channel reaches a value of 3530 microCuries per second (µCi/s) and goes into Alert Alarm. When the main vent stack radiation monitor is in accident mode, EDCP compensates by calculating assumed iodine and particulate release rates, using a noble

gas to iodine ratio. A default ratio of 10 is assumed (e.g., the iodine release rate is set to

10 percent of the measured noble gas release rate). Users identified that during the

November 13, 2012, exercise; EDCP did not appear to be applying the expected noble gas to iodine ratio when the vent stack radiation monitor was in accident mode. On

- 5 - November 7, 2013, the licensee confirmed that EDCP was not correctly applying the default noble gas to iodine ratio when the monitor was in accident mode, resulting in an overestimate of the concentration of iodine and particulates by a factor of 10, and an overestimate of the Thyroid Committed Dose Equivalent. The licensee put interim

compensatory measures in place on November 8, 2013, to ensure that inaccurate

information was not used in the determining protective action recommendations; the

licensee directed that dose assessment be considered as 'not available' when a radiological release was through the main stack with the effluent radiation monitor in accident mode. The licensee determined this problem existed in EDCP, Version 4.7, implemented on September 13, 2012, and in EDCP, Version 4.8, implemented on

October 28, 2013.

EDCP is a licensee-written program, maintained by the licensee's Information Systems Department. The licensee initiated Service Request 126710 to the Information Systems Department on January 10, 2013, to investigate the apparent inaccuracies in EDCP

calculations and, if confirmed, to correct the problem. The licensee reported on

November 7, 2013, that the Information Systems Department had not performed any work on Service Request 126710, and that an analyst and due date were not currently assigned. The licensee corrected the inaccurate calculation in EDCP, Version 4.9, implemented on February 25, 2014.

The inspectors determined that Chemistry Technicians were trained as Dose Assessors

and Chemists were trained as Radiological Assessment Coordinators. Training for these individuals was conducted during routinely scheduled chemistry department training sessions. The licensee informed the chemistry technicians and chemists about the apparent inaccuracy in EDCP calculations during training cycles 13-Q2, April 15 through

May 21, 2013, and 13-Q3, July 8 through August 15, 2013. Analysis. The inspectors determined that the failure to maintain a dose assessment process capable of providing a technically adequate estimate of offsite dose is a performance deficiency within the licensee's control. This finding is more than minor

because it affected the licensee's ability to implement adequate measures to protect the health and safety of the public. The finding also affected the facilities and equipment

and emergency response organizations performance cornerstone attributes. The finding was associated with a violation of NRC requirements. This finding was evaluated using IMC 0609, Appendix B, "Emergency Preparedness Significance Determination Process," and was evaluated in accordance with Attachment 2. The finding was preliminarily

determined to be of low to moderate safety significance (White) because it was a failure

to comply with NRC requirements and was a degraded risk significant planning standard function. The planning standard function was degraded because methods to assess the offsite consequences of a radiological release via the main vent stack pathway were inaccurate between September 13, 2012, and November 8, 2013. However, these

errors did not affect other calculations performed by the EDCP. This issue has been

entered into the licensee's corrective action system as Condition Report 2013-0076247.

A cross-cutting aspect of evaluation in the problem identification and resolution area was

assigned to this finding because the finding is representative of current performance and the licensee failed to promptly evaluate whether a problem existed with the Electronic Dose Calculation Program after an issue was raised following the November 13, 2012,

EP exercise. The licensee failed to verify the existence of a safety-significant problem and subsequently, failed to resolve the problem within a timeframe appropriate to its

safety significance [P.2].

- 6 - Enforcement. Title 10 of the Code of Federal Regulations (CFR), Part 50.54(q)(2), requires, in part, that the holder of a nuclear power reactor operating license shall follow and maintain the effectiveness of an emergency plan that meets the planning standards of 10 CFR 50.47(b). Title 10 CFR Part 50.47(b)(9) requires, in part, that the onsite and

offsite emergency response plans must use adequate methods for assessing and

monitoring actual or potential offsite consequences of a radiological emergency condition.

Contrary to the above, between September 13, 2012, and November 8, 2013, the licensee failed to maintain an emergency plan that used adequate methods for

assessing and monitoring the actual or potential offsite consequences of a radiological

emergency condition. Specifically, a calculational error in the licensee's Electronic Dose

Calculation Program resulted in inaccurate offsite doses for the main vent stack pathway when the effluent radiation monitor was in the accident mode: AV 05000482/2013502-01 (Failure to Maintain Accurate Methods for Dose Assessment).

1EP8 Exercise Evaluation (71114.08) a. Inspection Scope The licensee submitted the preliminary scenario for the 2013 biennial emergency preparedness exercise on September 3, 2013, in accordance with the requirements of

Appendix E to 10 CFR 50, Part IV.F(2)(b). The inspectors performed an in-office review

of the preliminary exercise scenario to determine whether the scenario would acceptably test the major elements of the licensee's emergency plan and provided opportunities to demonstrate the key emergency response organization skills. b. Findings No findings were identified.

4. OTHER ACTIVITIES 4OA1 Performance Indicator Verification (71151) .13 Drill/Exercise Performance (EP01) a. Inspection Scope The inspectors sampled licensee submittals for the Drill and Exercise Performance, performance indicator for the period July 2012 through September 2013. The definitions

and guidance of Nuclear Energy Institute Document 99-02, "Regulatory Assessment

Performance Indicator Guideline," Revision 6, were used to determine the accuracy of

the performance indicator data reported to the NRC. The inspectors reviewed the licensee's records associated with the performance indicator to verify that the licensee accurately reported the indicator in accordance with relevant procedures and the

Nuclear Energy Institute guidance. Specifically, the inspectors reviewed licensee

records and processes including procedural guidance on assessing opportunities for the

performance indicator; assessments of performance indicator opportunities during predesignated control room simulator training sessions, performance during the 2013 biennial exercise, and performance during other drills. The specific documents reviewed

are described in the attachment to this report.

- 7 - These activities constitute completion of the drill/exercise performance sample as defined in Inspection Procedure 71151-05. b. Findings No findings were identified. .14 Emergency Response Organization Drill Participation (EP02) a. Inspection Scope The inspectors sampled licensee submittals for the Emergency Response Organization Drill Participation performance indicator for the period July 2012

through September 2013. The definitions and guidance of Nuclear Energy Institute

Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 6, were used to determine the accuracy of the performance indicator data reported to the NRC. The inspectors reviewed the licensee's records associated with the performance indicator to verify that the licensee accurately reported the indicator in accordance with

relevant procedures and the Nuclear Energy Institute guidance. Specifically, the

inspectors reviewed licensee records and processes including procedural guidance on assessing opportunities for the performance indicator, rosters of personnel assigned to key emergency response organization positions, and exercise participation records. The

specific documents reviewed are described in the attachment to this report.

These activities constitute completion of the emergency response organization drill

participation sample as defined in Inspection Procedure 71151-05. b. Findings No findings were identified. .15 Alert and Notification System (EP03) a. Inspection Scope The inspectors sampled licensee submittals for the Alert and Notification System performance indicator for the period July 2012 through September 2013. The definitions and guidance of Nuclear Energy Institute Document 99-02, "Regulatory Assessment

Performance Indicator Guideline," Revision 6, were used to determine the accuracy of

the performance indicator data reported to the NRC. The inspectors reviewed the licensee's records associated with the performance indicator to verify that the licensee accurately reported the indicator in accordance with relevant procedures and the

Nuclear Energy Institute guidance. Specifically, the inspectors reviewed licensee

records and processes including procedural guidance on assessing opportunities for the

performance indicator and the results of periodic alert notification system operability tests. The specific documents reviewed are described in the attachment to this report.

These activities constitute completion of the alert and notification system sample as

defined in Inspection Procedure 71151-05.
