SUBJECT: COOPER NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT 05000298/2014005 AND EXERCISE OF ENFORCEMENT DISCRETION
Dear Mr. Limpias:
On December 31, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Cooper Nuclear Station. On January 15, 2015, the NRC inspectors discusse d the results of this inspection with you and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report.
NRC inspectors documented one finding of very low safety significance (Green) in this report. This finding involved a violation of NRC requirements. A violation involving the failure to maintain the operability of secondary containment during Operations with the Potential to Drain the Reactor Vessel (OPDRV) was identified. Specifically, from October 3, 2014, through October 22, 2014, Cooper Nuclear Station performed a total of 7 OPDRV activities with secondary containment inoperable in violation of Technical Specification 3.6.4.1, "Secondary Containment." The NRC issued EGM 11
-003, "Enforcement Guidance Memorandum on Dispositioning Boiling Water Reactor Licensee Noncompliance with Technical Specification Containment Requirements During Operations with a Potential for Draining the Reactor Vessel," Revision 2, on December 13, 2013, allowing for the exercise of enforcement discretion for such OPDRV
-related TS violations, when certain criteria are met. The NRC concluded that Cooper Nuclear Station met these criteria. Therefore, I have been authorized, after consultation with the Director, Office of Enforcement to exercise enforcement discretion in accordance with Section 3.5, "Violations Involving Special Circumstances," of the NRC Enforcement Policy and, therefore, will not issue enforcement action for this violation, subject to a timely license amendment request being submitted.

- 12/31/2014
- Cooper Nuclear Station
- Follow-up of Events and Notices of Enforcement Discretion.
The inspection activities described in this report were performed between October 1 and December 31, 2014, by the resident inspectors at the Cooper Nuclear Station and inspectors from the NRC's Regi on IV office. One finding of very low safety significance (Green) was documented in this report. T h is finding involved a violation of NRC 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, "Aspects within the Cross-Cutting Areas." Violations of NRC requirements are dispositioned in accordance with the NRC Enforcement Policy.
The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG
-1649, "Reactor Oversight Process."
Cornerstone: Barrier Integrity
- Green.
The inspectors reviewed a self-revealing, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," associated with the licensee's failure to follow Special Procedure GEH-TP-116, "Procedure for the Operation and Maintenance of the REM*TAKE
-2/D-100 Modified REM*TAKE 2," Revision 3, for post-maintenance testing following corrective maintenance. Specifically, the licensee did not follow post-maintenance testing requirements associated with the calibration of the bleeder valve for the REM*TAKE
-2/D-100 tool following corrective maintenance to address water intrusion. This resulted in the bleeder valve being misadjusted and nullifying the fail-safe feature of the REM*TAKE
-2/D-100 tool. With the fail-safe nullified
, Control Rod Blade 30-47 became disengaged from the REM*TAKE
-2/D-100 tool and dropped onto the reactor core top guide when the supplemental employee inadvertently pressed the disengage button. No reactor fuel was damaged as indicated by normal radiation levels and air samples on the refuel floor and reactor water coolant samples. The licensee's immediate corrective actions for the event was to suspended all in-vessel maintenance activities and remove REM*Take-2/D-100 grapple from service and determined functionality of the tool. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR-CNS-2014-06809. The licensee's failure to follow the post-maintenance testing requirements in Special Procedure GEH-TP-116 was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the human performance attribute of the Barrier Integrity Cornerstone and affected the associated objective of maintaining functionality of fuel cladding. Specifically, with the fail-safe nullified, Control Rod Blade 30-47 became disengaged from the REM*TAKE
-2/D-100 tool and dropped onto the reactor core top guide when a supplemental employee inadvertently pressed the disengage button. Using Inspection Manual Chapter 0609, Appendix G, Attachment 1, "Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings," dated May 09, 2014, inspectors determined that the finding was of very low safety significance (Green) because the finding did not impact the fuel barrier because it
- (1) does not increase the potential for failure of the freeze seal or if unmitigated have the potential to cause a disruption of residual heat removal/decay heat removal or a loss of inventory event; (2)does not involve two or more adjacent control rods with the potential to, or actually, add postive reactivity; and (3)does not degrade the ability to isolate a drain down or leakage path.
The finding has a cross-cutting aspect in the area of human performance associated with the field presence component because the licensee failed to ensure supervisory and management oversight of work activities including contractors and supplemental personnel
[H.2]. (Section 4OA3)

4OA 2 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 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

.2 Semi annual Trend Review
a. Inspection Scope
The inspectors reviewed the licensee's corrective action program, performance indicators, system health reports, and other documentation to identify trends that might indicate the existence of a more significant safety issue. The inspectors verified that the licensee was taking corrective actions to address identified adverse trends.
These activities constitute completion of one semiannual trend review sample , a s defined in Inspection Procedure 71152. This sample review ed the following condition reports (CR) and learning opportunities (LO):
CR-CNS-2014-05233 CR-CNS-2014-05366 CR-CNS-2014-02290 CR-CNS-2014-09663 LO-2014-0051-20 b. Observations and Assessments The station performed a focused self
-assessment on operability reviews from July 29 through July 31, 2014. The station has received NRC
-identified findings associated with the failure to recognize the need for an evaluation and to properly document the bases for operability when a degraded nonconforming condition was identified and failure to follow the requirements of Station Procedure 0.5OPS, "Operations Review of Condition Reports/Operability Determination." This assessment was performed to measure the effectiveness of changes to Station Procedure 0.5OPS. The period assessed was 1 year prior to the performance of the assessment. Additionally, the station's operability process was compared to industry best practices.
The station identified the following observation during the assessment period:
The station identified two examples where Station Procedure 0.5OPS is not completely aligned with NRC Inspection Manual Chapter 0326, "Operability Determinations and Functionality Assessments for Conditions Adverse to Quality and Safety," dated January 31, 2014, nor industry standards.
1. Station Procedure 0.5OPS allowed up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to complete an immediate determination prior to entering the prompt determination process. 2. The definitions of prompt determination and operability evaluation are combined. Industry best practices contain a separate definition for operability evaluation thus removing any confusion that the senior reactor operator makes the determination.
The station initiated Condition Report CR
-CNS-2014-05233 to capture this issue in the station's corrective action program. The station identified the following cause contributors:
1. Station Procedure 0.5OPS, Attachment 1, flowchart contains a decision block that if additional information is expected within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> then to request engineering input to support an immediate determination. If the additional information is not expected with 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, then the flowchart directs performance of an operability evaluation to support a prompt determination.
2. The definitions of prompt determination and operability evaluation are combined definitions in Station Procedure 0.5OPS. The discussion regarding timeliness of prompt determinations from Inspection Manual Chapter 0326 and industry best practices was not included in the station's definition.
The station implemented corrective actions to revise Station Procedure 0.5OPS to remove the allowance of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to perform an immediate determination. Also
, the station separated the definitions of prompt determination and operability evaluation and included a discussion regarding timeliness of prompt determinations.
The inspectors reviewed the focus self
-assessment and Condition Report CR-CNS-2014-05233. The inspectors noted the following observation. Station Procedure 0.5OPS, Revision 52, contained the following definition for mission time, "For operability determination purposes, the duration of structures, systems, and components operation that is credited in the design basis for the structures, systems, and components to perform its specified safety function (RIS 2005-20, Revision 1). Emergency diesel generators mission time is not specified in the current licensing basis and has been determined to be as long as the emergency diesel generators are required."
The inspectors reviewed the current licensing basis and noted the following contained in USAR Section VII-5.2 Safety Design, "The diesel generator set shall be capable of automatic start at any time and capable of continued operation at rated load, voltage, and frequency until manually stopped. USAR Section XIV requires each diesel generator set to be operable for a 30 day mission time to support its safety objective for postulated design basis accidents." The station initiated Intranet Documents Control System 66781 to revise/clarify Station Procedure 0.5OPS to reflect the current licensing basis mission time for the emergency diesel generators. Additionally, the inspectors reviewed operability evaluations associated with the emergency diesel generators for the past year and did not identify any evaluations that used the inappropriate emergency diesel generator mission time.

-up samples, as defined in Inspection Procedure 71153.
.1 Dropped Control Rod
a. Inspection Scope
On October 1 1 , 2014 , the inspectors were informed by the control room that while removing Control R od Blade 30-47 from the core, the control rod blade disengaged from the removal tool and dropped onto the reactor top guide. The inspectors monitored the licensee's actions for control rod blade recovery, reviewed station logs, and reviewed NUREG-1022, "Event Reporting Guidelines," Revision 3, to ensure licensee compliance.
b. Findings
Introduction.
The inspectors reviewed a self-revealing, Green, non
-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," associated with the licensee's failure to follow Special Procedure GEH-TP-116, "Procedure for the Operation and Maintenance of the REM*TAKE
-2/D-100 Modified REM*TAKE 2," Revision 3, for post
-maintenance testing following corrective maintenance.
Description.
On October 11, 2014, the licensee conducted control rod blade shuffles in support of Refueling Outage 28 operations. While removing Control R od Blade 30-47 from the core, the control rod blade disengaged from the REM*TAKE
-2/D-100 removal tool and dropped onto the reactor core top guide. Follow-up reactor coolant water samples revealed that no reactor fuel was damaged during this event. The licensee subsequently initiated Condition Report CR
-CNS-2014-06809. The licensee's root cause evaluation
, performed under CR
-CNS-2014-06809 , determined that the dropping of Control Rod B l a de 30-47 was caused by , "the calibration of the bleeder valve [that] was not validated in accordance with Special Procedure GEH-TP-116, "Procedure for the Operation and Maintenance of the REM*TAKE-2/D-100 Modified REM*TAKE 2," Revision 3, following corrective maintenance prior to operation of the REM*TAKE
-2/D-100 tool." Specifically, Special Procedure GEH-TP-116 , Step 7.2.4.7 was not completed , which defines the acceptable calibration of the bleeder valve. Specifcally , Step 7.2.4.7 states
, that , "Acceptable movement: The grippers should retract first and then 3 to 5 seconds later the control rod blade hook should actuate. This should be in sequence. If not, adjust the bleeder valve (turning clockwise to decrease flow or counter clockwise to increase flow) as need ed and repeat Sections 7.2.4.4 through 7.2.4.6 until there is acceptable movement."
The inspectors determined that the failure to accomplish Step 7.2.4.7 resulted in the bleeder valve being out of calibration
, which nullified the fail
-safe feature of the tool.
With the fail-safe feature nullified , Control R od Blade 30-47 became disengaged from the tool and dropped onto the reactor core when the supplemental employee inadvertently pressed the disengage button.
The licensee subsequently identified that the station did not exercise sufficient oversight of the fuel handler contractor to verify that the fail
-safe feature was fully functional after water clearing activities because the contractor was considered an expert in this type of work and in the use of the new type REM*TAKE
-2/D-100 tool. The inspectors reviewed the licensee's root cause analysis and determined that the identified root cause was reasonable.
Analysis.
The licensee's failure to follow the post-maintenance testing requirements in Special Procedure GEH-TP-116 was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the human performance attribute of the Barrier Integrity Cornerstone and affected the associated objective of maintaining functionality of fuel cladding. Specifically, with the fail-safe nullified Control Rod Blade 30-47 became disengaged from the REM*TAKE-2/D-100 tool and dropped onto the reactor core top guide. Using Inspection Manual Chapter 0609, Appendix G, Attachment 1, "Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings," dated May 09, 2014, inspectors determined that the finding was of very low safety significance (Green) because the finding did not impact the fuel barrier because it
- (1) does not increase the potential for failure of the freeze seal or if unmitigated have the potential to cause a disruption of residual heat removal/decay heat removal or a loss of inventory event; (2)does not involve two or more adjacent control rods with the potential to, or actually, add postive reactivity; and (3)does not degrade the ability to isolate a drain down or leakage path.
The finding has a cross
-cutting aspect in the area of human performance associated with the field presence component because the licensee failed to ensure supervisory and management oversight of work activities, including contractors and supplemental personnel
[H.2].
Enforcement.
Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality shall be prescribed b y documented instructions, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, and drawings. Safety-related Special Procedure GEH TP 116, "Procedure for the Operation and Maintenance of the REM*TAKE 2/D 100 Modified REM*TAKE 2," Revision 3, Step 7.2.4.7, specified that, "Acceptable movement: The grippers should retract first and then 3 to 5 seconds later the control rod blade hook should actuate. This should be in sequence. If not, adjust the bleeder valve (turning clockwise to decrease flow or counter clockwise to increase flow) as needed and repeat Sections 7.2.4.4 through 7.2.4.6 until there is acceptable movement."
Contrary to the above, on October 10, 2014, the licensee failed to accomplish activities affecting quality in accordance with documented instructions appropriate to the circumstances. Specifically, the licensee failed to accomplish Step 7.2.4.7 of Special Procedure GEH-TP-116 which resulted in the bleeder valve being misadjusted and nullified the fail-safe feature of the REM*TAKE-2/D-100 tool. The licensee's immediate corrective actions for the event was to suspended all in
-vessel maintenance activities and remove REM*Take
-2/D-100 grapple from service and determined functionality of the tool.
Because this violation was of very low safety significance and was entered into the licensee's corrective action program as Condition Report CR-CNS-2014-06809 , this violation is being treated as a non-cited violation, consistent with Section 2.3.2.a of the NRC's Enforcement Policy.

.2 (Close d) Licensee Event Report (LER) 05000298/2014004
-00, "Implementation of Enforcement Guidance Memorandum 11-003, Revision 2, Causes Conditions Prohibited by Technical Specifications"
a. Inspection Scope
During Refueling Outage 28, Cooper Nuclear Station performed Operations with a Potential for Draining the Reactor Vessel (OPDRV) activities while in Mode 5 without an operable secondary containment. An OPDRV is an activity that could result in the draining or siphoning of the reactor pressure vessel water level below the top of fuel, without crediting the use of mitigating measure to terminate the uncovering of fuel. Secondary containment is required by TS 3.6.4.1 to be operable during OPDRV. The required action for this specification is to suspend OPDRV operations. Therefore, entering the OPDRV without establishing secondary containment integrity was considered a condition prohibited by TS as defined by 10 CFR 50.73(a)(2)(i)(B).
The NRC issued Enforcement Guidance Memorandum (EGM) 11-003, Revision 2, on December 13, 2013, to provide guidance on how to disposition boiling water reactor licensee noncompliances with TS containment requirements during OPDRV operations. The NRC considers enforcement discretion related to secondary containment operability during Mode 5 OPDRV activities appropriate because the associated interim actions necessary to receive the discretion ensure an adequate level of safety by requiring licensees' immediate actions to:
- (1) adhere to the NRC plain language meaning of OPDRV activities,
- (2) meet the requirements which specify the minimum makeup flow rate and water inventory based on OPDRV activities with long drain down times,
- (3) ensure that adequate defense in depth is maintained to minimize the potential for the release of fission products with secondary containment not operable by
- (a) monitoring RPV level to identify the onset of a loss of inventory event,
- (b) maintaining the capability to isolate the potential leakage paths,
- (c) prohibiting Mode 4 (cold shutdown) OPDRV activities, and
- (d) prohibiting movement of irradiated fuel with the spent fuel storage pool gates removed in Mode 5, and
- (4) ensure that licensees follow all other Mode 5 TS requirements for OPDRV activities.
The inspectors reviewed this Licensee Event Report for potential performance deficiencies and/or violations of regulatory requirements. The inspectors reviewed the station's implementation of the Enforcement Guidance Memorandum 11-003, Revision 2, during operations with a potential for draining the reactor vessel. Specific observations included:
1. The inspectors observed that the operations with a potential for draining the reactor vessel activities were logged in the control room narrative logs, and that the log entry appropriately recorded the standby source of makeup designated for the evolutions.
2. The inspectors noted that the reactor vessel water level was maintained at least greater than 21 feet above the top of the reactor pressure vessel flange as required by Technical Specification 3.9.6. The inspectors also verified that at least one safety
-related pump was the standby source of makeup designed in the control room narrative logs for the evolutions. The inspectors confirmed that the worst case estimated time to drain the reactor cavity to the reactor pressure vessel flange was greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. 3. The inspectors verified that the operations with a potential for draining the reactor vessels were not conducted in Mode 4 and that the licensee did not move irradiated fuel during the operations with a potential for draining the reactor vessels. The inspectors verified that two independent means of measuring reactor pressure vessel water level were available for identifying the onset of loss of inventory events.
Technical Specification 3.6.4.1 requires, in part, that secondary containment shall be operable during operations with a potential for draining the reactor vessel. Technical Specification 3.6.4.1, Condition C, requires the licensee to initiate actions to suspend operations with a potential for draining the reactor vessel immediately when secondary containment is inoperable. Contrary to the above, from October 3, 2014 to October 22, 2014, Cooper Nuclear Station performed operations with a potential for draining the reactor vessel activities while in Mode 5 without an operable secondary containment. Specifically, the station conducted the following seven operations with a potential for draining the reactor vessel activities without an operable secondary containment:
Draining reactor recirculation pump without the jet pump plugs fully installed Control rod drive maintenance Removal of jet pump plugs associated with reactor recirculation pump B maintenance Venting the control rod drives Defeating the scram function for two control rod drives and support IVVI inspections Reactor recirculation pump A seal maintenance Control rod drive freeze seal These conditions were reported as conditions prohibited by Technical Specifications. The licensee entered this issue into its corrective action program as Condition Reports CR-CNS-2014-06293.
Since this violation occurred during the discretion period described in EGM 11
-003, Revision 2, the NRC is exercising enforcement discretion in accordance with Section 3.5, "Violations Involving Special Circumstances," of the NRC Enforcement Policy, and, therefore, will not issue enforcement action for this violation.
In accordance with EGM 11
-003, Revision 2, each licensee that receives discretion must submit a license amendment request within 4 months of the NRC staff's publication in the Federal Register of the notice of availability for a generic change to the standard TS to provide more clarity to the term OPDRV.
The Licensee Event Report is closed.

4OA 5 Other Activities (Discussed) Temporary Instruction 2515/190 - Inspection of the Licensee's Proposed Interim Actions as a Result of the Near
-Term Task Force Recommendation 2.1 Flooding Reevaluation
a. Inspection Scope
The inspector(s) completed a partial verification that the licensee's interim actions would perform their intended function for some beyond design basis flooding events. However, the licensee has determined that additional flooding mitigation strategies and equipment will be necessary to address the full spectrum of potential beyond design basis flooding events at the Cooper Nuclear Station. This additional review is scheduled to be completed during the Spring of 2015 after the licensee submits their Flood Hazard Reevaluation Report (FHRR). As a result, an additional inspection activity using Temporary Instruction 2515/190 will be performed following the completion of the licensee's review to verify that the additional strategies and equipment will perform their intended function for flooding mitigation.
During the partial verification of the licensee's interim actions, the inspectors reviewed
