Findings for which the significance determination process does not apply may be Green or be assigned a severity level after NRC management review. 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.
NRC-Identified Findings and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
The inspectors identified a non-cited violation of Technical Specification 5.4.1.a for the failure to follow procedure and remove items from containment.
As a result, maintenance personnel failed to remove materials that could be transported to the containment emergency core cooling sumps during an accident. The inspectors informed the licensee of the debris inside containment and the licensee corrected the condition. The licensee entered the finding into the corrective action program as Condition Report CR-2011-013343.
The failure of the maintenance personnel to follow procedure and remove materials from containment was a performance deficiency which resulted in debris remaining in containment. The finding was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of the emergency core cooling sumps.
Using NRC Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not represent an actual loss of safety function of the emergency core cooling sumps. The finding has a human performance crosscutting aspect associated with resources because the licensee failed to ensure that personnel performing the maintenance activity were adequately trained on the procedure requirement to remove the materials when leaving containment H2.b] (Section 1R20).
- Green.
The inspectors identified a non-cited violation of Technical Specification 5.4.1.a for the failure to follow procedure and correctly restore motor operated valves. As a result, the licensee inverted the Unit 1 power operated relief valve block valves limit switch covers and placed the drain on the top. The licensee entered the finding into the corrective action program as Condition Report CR-2011-011871.
The failure to follow procedure and correctly restore motor operated valves, which resulted in inverted limit switch covers with the drain on the top, was a performance deficiency. The finding was more than minor because if left uncorrected, the performance deficiency had the potential to lead to a more significant safety concern in that other valves may have been incorrectly restored. The inspectors determined that the finding was associated with the mitigating systems cornerstone. Using NRC Manual Chapter 0609,
Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not represent an actual loss of safety function of the power operated relief valve block valves. The finding has a human performance crosscutting aspect associated with work practices because the licensee failed to use appropriate self and peer checking H.4a] (Section 1R20).
- Green.
The inspectors identified a non-cited violation of 10 CFR Part 50,
Appendix B, Criterion XVI, for the failure of the licensee to promptly identify and correct improper auxiliary feedwater pump oil levels. As a result, the inspectors identified seven instances where the oil level was outside of the prescribed sight glass indication. The licensee entered the finding into the corrective action program as Condition Report CR-2011-12430.
The licensees failure to promptly identify and correct the improper auxiliary feedwater pump bearing oil level was a performance deficiency. The finding was more than minor because if was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of the auxiliary feedwater pumps. Using NRC Manual Chapter 0609, Attachment 4,
Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not result in an actual loss of safety function of an auxiliary feedwater pump. The finding has a problem identification and resolution crosscutting aspect associated with corrective action program, in that, licensee personnel failed to trend and assess the abnormal oil level condition reports in the aggregate to identify common cause problems P.1b] (Section 4OA2).
Cornerstone: Emergency Preparedness
- Green.
The inspectors identified a non-cited violation of 10 CFR 50.47(b)(10) for failure of the licensee to have guidelines developed and in place for the choice of protective actions during an emergency. Specifically, Procedure EPP-304,
Protective Action Recommendations, Revision 20, did not provide direction for the development of protective action recommendations outside the emergency planning zone. The licensee entered the finding into the corrective action program as Condition Report CR-2011-009218.
The failure to develop and implement guidelines for the choice of protective actions during an emergency is a performance deficiency. This finding is more than minor because it has the potential to affect safety, and affects the emergency preparedness cornerstone attributes of emergency response organization performance and procedure quality. The finding is of very low safety significance because it was a failure to comply with NRC requirements, was associated with a risk-significant planning standard, and was not a functional failure of the planning standard or degraded planning standard function. The finding has a problem identification and resolution crosscutting aspect associated operating experience because the licensee did not use operating experience to maintain and update the protective action procedure P2.b] (Section 1EP1).
Cornerstone: Occupational Radiation Safety
- Green.
The inspectors reviewed a self-revealing non-cited violation of 10 CFR 20.1501(a) because radiation protection staff failed to perform an adequate survey to evaluate and determine the radiological hazards in the floor drain tank room. The licensee entered the finding into the corrective action program as Condition Report CR-2011-010174 and immediately posted the room as a locked high radiation area.
The failure to perform a radiation survey to determine radiological hazards was a performance deficiency. The finding was greater than minor because it was associated with the occupational radiation safety cornerstone attribute of program and process and affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation during routine operations. Using NRC Manual Chapter 0609, Significance Determination Process, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because: (1) it was not associated with as low as is reasonably achievable (ALARA) planning (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. The finding has a human performance crosscutting aspect associated with work control because the licensee failed to ensure interdepartmental communication and coordination prior to commencing work activities and assuring accurate radiation safety information was provided to workers H.3b] (Section 2RS01).
- Green.
The inspectors reviewed a self-revealing non-cited violation of Technical Specification 5.4.1.a for the failure of a worker to follow radiological work permit requirements. Specifically, a chemistry technician received a dose rate alarm that was greater than 120 millirem per hour and failed to immediately exit the area and contact radiation protection. The licensee entered the finding into the corrective action program as Condition Report CR-2011-010774.
The failure to follow the instructions on a radiation work permit by not immediately contacting radiation protection when a dose rate alarm was received was a performance deficiency. The finding was more than minor because it was associated with the occupational radiation safety cornerstone attribute of program and process and affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation during routine operations. Using NRC Manual Chapter 0609, Significance Determination Process, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because: (1) it was not associated with as low as is reasonably achievable (ALARA) planning or work controls, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. The finding has a human performance crosscutting aspect associated with work practices because the licensee failed to effectively communicate expectations regarding procedural compliance to the worker H.4b] (Section 2RS01).
Licensee-Identified Violations
Two violations of very low safety significance were identified by the licensee and were reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. These violations and corrective action condition report numbers are listed in Section 4OA7.

1R20 Refueling and Other Outage Activities
a. Inspection Scope
The inspectors reviewed the outage safety plan and contingency plans for the Unit 1 refueling outage, conducted October 1, 2011 through October 22, 2011, to confirm that licensee personnel had appropriately considered risk, industry experience, and previous
site-specific problems in developing and implementing a plan that assured maintenance of defense-in-depth. During the refueling outage, the inspectors observed portions of the shutdown and cooldown of the reactor and monitored licensee controls over the outage activities listed below:
- Configuration management, including maintenance of defense-in-depth, is commensurate with the outage safety plan for key safety functions and compliance with the applicable technical specifications when taking equipment out of service
- Clearance activities, including confirmation that tags were properly hung and equipment appropriately configured to safely support the work or testing
- Installation and configuration of reactor coolant pressure, level, and temperature instruments to provide accurate indication, accounting for instrument error
- Status and configuration of electrical systems to ensure that technical specifications and outage safety plan requirements were met, and controls over switchyard activities
- Monitoring of decay heat removal processes, systems, and components
- Verification that outage work was not impacting the ability of the operators to operate the spent fuel pool cooling system
- Reactor water inventory controls, including flow paths, configurations, and alternative means for inventory addition, and controls to prevent inventory loss
- Controls over activities that could affect reactivity
- Refueling activities including fuel handling
- Startup and ascension to full power operation, tracking of startup prerequisites, walkdown of the containment to verify that debris had not been left which could block emergency core cooling system suction strainers, and reactor physics testing
- Licensee identification and resolution of problems related to refueling outage activities
- Licensees management of fatigue Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one refueling outage sample as defined in Inspection Procedure 71111.20-05.
b. Findings
1. Failure to Remove Materials and Debris from Containment
Introduction.
The inspectors identified a Green non-cited violation of Technical Specification 5.4.1.a for the failure to follow procedure and remove items from containment. As a result, maintenance personnel failed to remove materials that could be transported to the containment emergency core cooling sumps during an accident.
Description.
On October 18, 2011, the inspectors performed a walkdown of the Unit 1 containment to look for debris and other materials that could be transported to the emergency sumps during an accident prior to the unit entering Mode 4. The inspectors observed a large amount of plastic, paper, and other debris remaining inside containment near the sumps. Maintenance personnel had initiated an emergent work activity on a component cooling water drain tank pump and had left the job area for the day. The maintenance personnel planned on completing the activity the following day.
The shift manager had implemented the requirement for Mode 4 cleanliness which required that materials taken into containment be removed from containment when a person exits containment. The licensee had completed the containment closeout inspection prior to the initiation of the emergent activity. The inspectors informed the licensee of the debris inside containment and the licensee corrected the condition.
The inspectors reviewed Condition Report CR-2011-013343 and discussed the observation with the maintenance personnel. The inspectors determined that the licensee failed to ensure that the personnel performing the maintenance activity were properly trained on the containment entry administrative procedure requirement to remove debris when exiting containment.
Analysis.
The failure of the maintenance personnel to follow procedure and remove materials from containment was a performance deficiency which resulted in debris remaining in containment. The finding was more than minor because if was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of the emergency sumps. Using NRC Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not represent an actual loss of safety function of the emergency core cooling sumps. The finding has a human performance crosscutting aspect associated with resources because the licensee failed to ensure that personnel performing the maintenance activity were adequately trained on the procedure requirement to remove the materials when leaving containment
H2.b].
Enforcement.
Technical Specification 5.4.1.a requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A. Regulatory Guide 1.33, Revision 2, Appendix A, Item 1.i, requires, in part, procedures for access to containment. Procedure STA-620, Containment Entry, Revision 12, in part, delineates responsibilities and provides instructions to safely enter containment. Step 6.1.9 of the procedure requires, in part, that individuals are responsible for ensuring that any equipment, personal items, test equipment, clip boards, note paper, or similar items, inherently required for the activity are still in their possession upon exit of containment.
Contrary to the above, on October 18, 2011, maintenance personnel failed to ensure all materials required for the activity were in their possession upon exit of containment.
After being informed of the debris, the licensee directed personnel to reenter containment and remove the materials. Since the violation was of very low safety
significance and was documented in the licensees corrective action program as Condition Report CR-2011-013343, it is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000445/2011005-01, Failure to Remove Materials and Debris from Containment.
2. Failure to Correctly Reassemble a Motor Operated Valve
Introduction.
The inspectors identified a Green non-cited violation of Technical Specification 5.4.1.a for the failure to follow procedure and correctly restore motor operated valves. As a result, the licensee inverted the Unit 1 power operated relief valve block valves limit switch covers and placed the drain on the top.
Description.
On October 18, 2011, the inspectors performed a walkdown of the Unit 1 containment while the unit was in Mode 5. The inspectors identified that the power operated relief valve block valves 1-8000A and 1-8000B had inverted limit switch covers and placed the drain on the top. The inspectors determined that the valves were not in the environmentally qualified configuration. In the required configuration, the drain would be located on the bottom of the limit switch cover in order to drain moisture.
However, the valves were not required to be operable in Mode 5. The licensee corrected the condition the same day before entering Mode 4. The inspectors noted that the same procedure is used to perform testing on other environmentally qualified motor operated valves in the plant. The inspectors performed a walkdown of other valves and found no problems.
The inspectors reviewed the licensees causal analysis for the inverted drains. The licensee determined that maintenance personnel failed to follow procedure when restoring the valve from testing during the refueling outage. The licensee had performed a pre-job briefing that covered correct drain orientation. However, the maintenance personnel did not adequately self and peer check.
Analysis.
The failure to follow procedure and correctly restore motor operated valves, which resulted in inverted limit switch covers with the drain on the top, was a performance deficiency. The finding was more than minor because if left uncorrected, the performance deficiency had the potential to lead to a more significant safety concern in that other valves may have been incorrectly restored. The inspectors determined that the finding was associated with the mitigating systems cornerstone. Using NRC Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not represent an actual loss of safety function of the power operated relief valve block valves. The finding has a human performance crosscutting aspect associated with work practices because the licensee failed to use appropriate self and peer checking H.4a].
Enforcement.
Technical Specification 5.4.1.a requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A. Regulatory Guide 1.33, Revision 2, Appendix A, Item 9.a, requires, in part, that maintenance that can affect the performance of safety-related equipment should be performed in accordance with written procedures. Procedure PPT-S0-6004, Motor Operated Rising Stem Valve Risk-Informed IST Testing, Revision 5, step 9.3 requires, in part, to restore the motor operated valve. Contrary to the above, from October 7, 2011 to October 18, 2011 the
licensee failed to restore the motor operated valve. Specifically, the limit switch covers were inverted, which caused the drain to be on top of the cover. The licensee corrected the cover orientation on October 18, 2011. Since the violation was of very low safety significance and was documented in the licensees corrective action program as Condition Report CR-2011-011871, it is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000445/2011005-02, Failure to Correctly Reassemble a Motor Operated Valve.
1R22 Surveillance Testing

These activities constitute completion of five surveillance testing inspection samples (one pump or valve inservice test sample, one containment isolation valve test sample, and three routine surveillance testing samples) as defined in Inspection Procedure 71111.22-05.
b. Findings
No findings were identified.
1EP1 Exercise Evaluation
a. Inspection Scope
The inspectors reviewed the objectives and scenario for the 2011 biennial emergency plan exercise to determine if the exercise acceptably tested major elements of the emergency plan. The scenario simulated a reactor coolant system leak inside containment escalating into a large-break loss of coolant accident, a failure to completely insert control rods, a loss of containment spray systems, and a radiological release to the environment via the containment emergency escape hatch, to demonstrate the licensee personnels capability to implement their emergency plan.
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:
- 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 current revision of the facility emergency plan, emergency plan implementing procedures associated with operation of the licensees emergency response facilities, 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 exercise evaluation sample as defined in Inspection Procedure 71114.01-05.
b. Findings
Introduction.
The inspectors identified a Green non-cited violation of 10 CFR 50.47(b)(10) for failure of the licensee to have guidelines developed and in place for the choice of protective actions during an emergency. Specifically, Procedure EPP-304, Protective Action Recommendations, Revision 20, did not provide direction for the development of protective action recommendations outside the emergency planning zone.
Description.
The inspectors reviewed emergency plan implementing Procedure EPP-304, Protective Action Recommendations, Revision 20, and identified that step 4.1.5 stated that, If dose projections exceed EPA Protective Action Guidelines at the outer boundary of the 10-mile EPZ, then TDSHS-RCP will be contacted as soon as possible to formulate PARs for the affected areas.
The inspectors subsequently observed the biennial emergency preparedness exercise conducted August 3, 2011. During the exercise, the offsite radiological assessment coordinator in the emergency operations facility identified the 5 rem thyroid committed dose equivalent protective action guideline was met at 10 miles. The offsite radiological assessment coordinator informed the emergency coordinator of the need to evaluate protective actions outside the emergency planning zone. The inspectors determined that the emergency coordinator and offsite radiological assessment coordinator did not develop independent protective action recommendations for outside the emergency planning zone and the licensee emergency response organization did not transmit protective action recommendations for outside the emergency planning zone to offsite authorities.
The inspectors observed the licensees management briefing regarding exercise performance conducted August 5, 2011, and determined the exercise evaluation team evaluated the failure to develop protective action recommendations for areas outside the emergency planning zone as satisfactory performance. The inspectors subsequently interviewed the licensee emergency preparedness manager to verify the emergency coordinator and offsite radiological assessment coordinator had performed according to their procedure and training.
The inspectors determined that during the August 3, 2011, biennial exercise, the emergency coordinator and offsite radiological assessment coordinator performed in accordance with their procedures and training. The inspectors concluded that Procedure EPP-304 did not provide guidelines for the choice of protective actions during an emergency for those areas outside the emergency planning zone and did not ensure the licensee would develop protective action recommendations for these areas.
Analysis.
The failure to develop and implement guidelines for the choice of protective actions during an emergency is a performance deficiency. This finding is more than minor because it affected the emergency preparedness attributes of emergency response organization performance and procedure quality. The finding had a credible impact on the emergency preparedness cornerstone objective because the lack of guidelines for the choice of protective actions during an emergency may preclude the licensee from implementing measures to protect the health and safety of the public.
Using NRC Manual Chapter 0609, Significance Determination Process, Appendix B, Emergency Preparedness Significance Determination Process, the finding was determined to be of very low safety significance because it was a failure to comply with NRC requirements, was associated with a risk-significant planning standard, and was not a functional failure of the planning standard or degraded planning standard function.
The finding did not represent a degraded planning standard function because appropriate guidelines were developed and in place for choosing protective actions for members of the public within the emergency planning zone. The finding has a problem identification and resolution crosscutting aspect associated operating experience because the licensee did not use operating experience to maintain and update the protective action procedure P2.b].
Enforcement.
Title 10 of the CFR 50.47(b)(10) states, in part, that guidelines for the choice of protective actions during an emergency, consistent with Federal guidance, are developed and in place. Contrary to above, the licensee failed to have complete guidelines for the choice of protective actions during an emergency developed and in place. Specifically, licensee Procedure EPP-304, Protective Action Recommendations, Revision 20, did not provide direction for the development of protective action recommendations outside the emergency planning zone. Since the violation was of very low safety significance and has been entered into the licensees corrective action program as Condition Report CR-2011-009218, this violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy:
NCV 05000445/2011005-03; 05000446/2011005-03, "Failure to Provide Guidelines for Protective Action Recommendations outside the Emergency Planning Zone."
1EP4 Emergency Action Level and Emergency Plan Changes
a. Inspection Scope
The inspectors performed an in-office review and contacted the licensee to verify the licensee had not submitted changes to the emergency plan or emergency action level scheme to the NRC during 2011.
These activities constitute completion of one emergency action level and emergency plan changes inspection sample as defined in Inspection Procedure 71114.04-05.
b. Findings
No findings were identified.
RADIATION SAFETY
Cornerstone: Occupational and Public Radiation Safety
2RS0 1 Radiological Hazard Assessment and Exposure Controls
a. Inspection Scope
This area was inspected to:
- (1) review and assess licensees performance in assessing the radiological hazards in the workplace associated with licensed activities and the implementation of appropriate radiation monitoring and exposure control measures for both individual and collective exposures,
- (2) verify the licensee is properly identifying and reporting occupational radiation safety cornerstone performance indicators, and
- (3) identify those performance deficiencies that were reportable as a performance indicator and which may have represented a substantial potential for overexposure of the worker.
The inspectors used the requirements in 10 CFR Part 20, technical specifications, and the licensees procedures required by technical specifications as criteria for determining compliance. The inspectors interviewed the radiation protection manager, radiation protection supervisors, and radiation workers. The inspectors performed walkdowns of various portions of the plant, performed independent radiation dose rate measurements, and reviewed the following items:
- Performance indicator events and associated documentation reported by the licensee in the occupational radiation safety cornerstone
- The hazard assessment program, including a review of the licenses evaluations of changes in plant operations and radiological surveys to detect dose rates, airborne radioactivity, and surface contamination levels
- Instructions and notices to workers, including labeling or marking containers of radioactive material, radiation work permits, actions for electronic dosimeter alarms, and changes to radiological conditions
- Programs and processes for control of sealed sources and release of potentially contaminated material from the radiological controlled area, including survey performance, instrument sensitivity, release criteria, procedural guidance, and sealed source accountability
- Radiological hazards control and work coverage, including the adequacy of surveys, radiation protection job coverage, and contamination controls; the use of electronic dosimeters in high noise areas; dosimetry placement; airborne radioactivity monitoring; controls for highly activated or contaminated materials (non-fuel) stored within spent fuel and other storage pools; and posting and physical controls for high radiation areas and very high radiation areas
- Radiation worker and radiation protection technician performance with respect to radiation protection work requirements
- Audits, self-assessments, and corrective action documents related to radiological hazard assessment and exposure controls since the last inspection
Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of one radiological hazard assessment and exposure controls sample as defined in Inspection Procedure 71124.01-05.
b. Findings
1. Failure to Perform Adequate Radiation Surveys
Introduction.
The inspectors reviewed a self-revealing Green non-cited violation of 10 CFR 20.1501(a) because radiation protection staff failed to perform an adequate survey to evaluate and determine the radiological hazards in floor drain tank room 1-061.
Description.
On September 15, 2011, operations personnel entered floor drain tank room 1-061 to remove a clearance just inside the entrance. Room 1-061 was posted as a high radiation area, and the worker was on General Access Permit 20110011, which allowed entry to a high radiation area. However, the survey measurements used to brief operations prior to entry showed a maximum dose rate of 260 millirem per hour at 30 centimeters and 25 millirem per hour just inside the entrance. This survey was performed earlier that day, prior to the floor drain tank being drained, and before personnel entered room 1-061. Once drained, the general area dose rates increased significantly in room 1-061. Survey 11-09-0362, performed on September 16, 2011, showed a maximum dose rate of 450 millirem per hour at 30 centimeters. When operations entered room 1-061, a dose rate alarm of 218 millirem per hour was received.
General Access Permit 2011-0011 had a dose rate alarm setpoint of 80 millirem per hour. Thus, operations entered room 1-061 under unknown radiological conditions that potentially could have resulted in a significant amount of unintended dose. The licensee failed to properly survey the room post drain down of the floor drain tank and communicate accurate radiological hazards to individuals entering the room as necessary. When questioned, it was determined that personnel assumed that the survey used to communicate radiological conditions for room 1-061 was post drain down of the floor drain tank.
Analysis.
The failure to perform a radiation survey to determine radiological hazards was a performance deficiency. The finding was more than minor because it was associated with the occupational radiation safety cornerstone attribute of program and process and affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation during routine operations. Using NRC Manual Chapter 0609, Significance Determination Process, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because:
- (1) it was not associated with as low as is reasonably achievable (ALARA) planning
- (2) there was no overexposure,
- (3) there was no substantial potential for an overexposure, and
- (4) the ability to assess dose was not compromised. The finding has a human performance crosscutting aspect associated with work control because the licensee failed to ensure interdepartmental communication and coordination prior to commencing work activities and assuring accurate radiation safety information was provided to workers H.3b].
Enforcement.
Title 10 CFR 20.1501(a) requires, in part, that each licensee make or cause to be made surveys that may be necessary for the licensee to comply with the regulations in 10 CFR Part 20 and that are reasonable under the circumstances to evaluate the magnitude and extent of radiation levels, concentrations or quantities of
radioactive materials, and the potential radiological hazards that could be present.
Contrary to the above, on September 15, 2011, the licensee failed to take reasonable surveys of floor drain tank room 1-061 to evaluate the radiation levels and potential radiological hazards. Consequently, an individual received unintended and unexpected radiation exposure because the magnitude and extent of radiation levels and potential radiological hazards were not evaluated post drain down of the floor drain tank. Since the violation was of very low safety significance and has been documented in the licensees corrective action program as Condition Report CR-2011-010174, it is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000445/2011005-04, Failure to Perform Adequate Radiation Surveys.
2. Failure to Follow Radiological Work Permit Requirements
Introduction.
The inspectors reviewed a self-revealing Green non-cited violation of Technical Specification 5.4.1.a for the failure of a worker to follow radiological work permit requirements. Specifically, a chemistry technician received a dose rate alarm greater than 120 millirem per hour and failed to immediately exit the area and contact radiation protection.
Description.
On October 2, 2011, during Unit 1 Refueling Outage 15, a chemistry technician had been collecting a reactor coolant sample during the crud burst in room 1-078 when he received a dose rate alarm. The maximum dose rate received could not be determined because the electronic alarming dosimeter information was not retrieved before the dosimeter was returned and used for another entry. However, the dosimeter alarmed due to high dose rate, and therefore, exceeded the setpoint of 120 millirem per hour.
The reactor coolant sample was placed into a bucket that contained an electronic alarming dosimeter with a dose rate alarm setpoint of 80 millirem per hour. As part of the review of this event, it was determined that both dosimeters alarmed almost simultaneously. The technician incorrectly assumed that the alarm he heard was only due to the buckets electronic alarming dosimeter and he did not look at his dosimeter.
This event, as discussed by the plant event review committee meeting minutes, dated April 14, 2011, revealed that there were two opportunities missed by the technician to identify the dose rate alarms. The first occurred when the electronic alarming dosimeter on the sample bucket alarmed at the same time as the personal electronic alarming dosimeter. The second occurred when the technician exited the radiologically controlled area and the dose rate alarm was indicated on the access computer screen. The technician assumed the computer was incorrect because the alarm was not identified when the technician was working. The plant event review committee discussed that the technician may not have understood instructions for when a dose or dose rate alarm because chemistry procedures did not include detailed guidance for using an electronic alarming dosimeter to monitor radioactive samples and to respond to dosimeter alarms.
The committee acknowledged that supervisory oversight could be enhanced by clarifying guidance provided by chemistry procedures. The licensee placed the finding into the corrective action program as Condition Report CR-2011-010774.
Analysis.
The failure to follow the instructions on a radiation work permit by not immediately contacting radiation protection when a dose rate alarm was received was a performance deficiency. The finding was more than minor because it was associated with the occupational radiation safety cornerstone attribute of program and process and
affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation during routine operations. Using NRC Manual Chapter 0609, Significance Determination Process, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because:
- (1) it was not associated with as low as is reasonably achievable (ALARA) planning or work controls,
- (2) there was no overexposure,
- (3) there was no substantial potential for an overexposure, and
- (4) the ability to assess dose was not compromised. The finding has a human performance crosscutting aspect associated with work practices because the licensee failed to effectively communicate expectations regarding procedural compliance to the worker
H.4b].
Enforcement.
Technical Specification Section 5.4.1.a requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A to Regulatory Guide 1.33, February 1978.
Regulatory Guide 1.33, Appendix A, Section 7(e) requires, in part, that radiation protection procedures for access control to radiation areas be established, including a radiation work permit system. Radiological Work Permit 2011-1103 stated that, If an unanticipated electronic dosimeter dose rate alarm is received then immediately exit the area and contact RP (radiation protection). Contrary to the above, on October 2, 2011, a chemistry technician failed to immediately exit the area and contact radiation protection when receiving an unanticipated dose rate alarm. Since this violation was of very low safety significance and was documented in the licensees corrective action program as Condition Report CR-2011-010774, it is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy:
NCV 05000445/2011005-05, Failure to Follow Radiological Work Permit Requirements.
2RS0 2 Occupational ALARA Planning and Controls
a. Inspection Scope
This area was inspected to assess performance with respect to maintaining occupational individual and collective radiation exposures as low as is reasonably achievable (ALARA). The inspectors used the requirements in 10 CFR Part 20, the technical specifications, and the licensees procedures required by technical specifications as criteria for determining compliance. During the inspection, the inspectors interviewed licensee personnel and reviewed the following items:
- Site-specific ALARA procedures and collective exposure history, including the current 3 year rolling average, site-specific trends in collective exposures, and source-term measurements
- ALARA work activity evaluations and postjob reviews, exposure estimates, and exposure mitigation requirements
- The methodology for estimating work activity exposures, the intended dose outcome, the accuracy of dose rate and man-hour estimates, and intended versus actual work activity doses and the reasons for any inconsistencies
- Records detailing the historical trends and current status of tracked plant source terms and contingency plans for expected changes in the source term due to changes in plant fuel performance issues or changes in plant primary chemistry
- Radiation worker and radiation protection technician performance during work activities in radiation areas, airborne radioactivity areas, or high radiation areas
- Audits, self-assessments, and corrective action documents related to ALARA planning and controls since the last inspection Specific documents reviewed during this inspection are listed in the attachment.

4OA2 Identification and Resolution of Problems
.1 Routine Review of Identification and Resolution of Problems
a. Inspection Scope
As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensees corrective action program at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. The inspectors reviewed attributes that included: the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensees corrective action program because of the inspectors observations are included in the attached list of documents reviewed.
These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure, they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.
b. Findings
No findings were identified.
.2 Daily Corrective Action Program Reviews
a. Inspection Scope
In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees corrective action program. The inspectors accomplished this through review of the stations daily corrective action documents.
The inspectors performed these daily reviews as part of their daily plant status monitoring activities, so these reviews and did not constitute any separate inspection samples.
b. Findings
No findings were identified.
.3 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensees corrective action program and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors focused the review on the condition reports actions associated with the refueling outage defense-in-depth program and equipment hatch closure. The licensee initiated Condition Report CR-2011-010973 to address the cause of negative trend in the defense-in-depth program. The inspectors reviewed documents and interviewed personnel to determine if the licensee completely and accurately identified problems in a timely manner commensurate with its significance, evaluated and dispositioned operability issues, considered the extent of condition, prioritized the problem commensurate with its safety significance, identified appropriate corrective actions, and completed corrective actions in a timely manner commensurate with the safety significance of the issue.
These activities constitute completion of one semi-annual trend inspection sample as defined in Inspection Procedure 71152-05.
b. Findings
No findings were identified.
.4 Selected Issue Follow-up Inspection
a. Inspection Scope
During a review of items entered in the licensees corrective action program, the inspectors recognized corrective action items associated with the auxiliary feedwater pump oil levels. The inspectors reviewed documents and interviewed personnel to determine if the licensee completely and accurately identified problems in a timely manner commensurate with its significance, evaluated and dispositioned operability issues, considered the extent of condition, prioritized the problem commensurate with its safety significance, and completed corrective actions in a timely manner commensurate with the safety significance of the issue.
These activities constitute completion of one in-depth problem identification and resolution sample as defined in Inspection Procedure 71152-05.
b. Findings
Introduction.
The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, for the failure of the licensee to promptly identify and correct
improper auxiliary feedwater pump oil levels. As a result, the inspectors identified seven instances where the oil level was outside of the prescribed sight glass indication.
Description.
Between July 12, 2011, and November 2, 2011, the inspectors identified seven instances where the auxiliary feedwater pumps oil level was outside of the prescribed sight glass indication. In five instances the oil level was high and in two instances the oil level was low. The licensee initiated condition reports to document the inspectors observation. In addition, the licensee identified several instances where the oil level was outside the prescribed band and documented these occurrences as condition reports in the corrective action program. The licensee initiated work instructions and had the oil levels returned to the correct level.
The inspectors reviewed the condition reports that documented the level discrepancies and discussed the issue with engineering. The higher oil level would result in a slight increase in bearing oil temperature. The lower oil level remained above the previous operating band for the pumps prior to a design change that raised the operating band level. The inspectors determined that the pumps were always operable.
The inspectors determined that, although the licensee identified some instances where the oil level was outside the prescribed range and corrected the level, there were several instances that the licensee failed to identify the abnormal level. In addition, the licensee failed to adequately trend and assess the condition reports to identify an overall auxiliary feedwater pump oil level issue.
Analysis.
The licensees failure to promptly identify and correct the improper auxiliary feedwater pump bearing oil level was a performance deficiency. The finding was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of the auxiliary feedwater pumps. Using NRC Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not result in an actual loss of safety function of an auxiliary feedwater pump. The finding has a problem identification and resolution crosscutting aspect associated with corrective action program, in that, licensee personnel failed to trend and assess the abnormal oil level condition reports in the aggregate to identify common cause problems P.1b].
Enforcement.
Title 10 CFR Part 50, Appendix B, Criterion XVI, requires, in part, that measures shall be established to assure that conditions adverse to quality, such as deficiencies, are promptly identified and corrected. Contrary to the above, between July 12, 2011, and November 2, 2011, in seven instances, the licensee failed to promptly identify and correct a condition adverse to quality where the auxiliary feedwater pump bearing oil levels were outside the normal operating range. The licensee returned the pump oil levels to the proper level when notified by the inspectors. Since the violation was of very low safety significance and was documented in the licensees corrective action program as Condition Report CR-2011-012430, it is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000445/2011005-06; 05000446/2011005-06, Failure to Identify Inadequate Auxiliary Feedwater Pump Bearing Oil Levels.
.5 Operator Workarounds
a. Inspection Scope
The inspectors reviewed the cumulative effects of the operator workarounds and burdens to determine the reliability, availability, and potential for incorrect operation of systems or components. The inspectors verified the ability of operators to respond in a correct and timely manner to plant transients and accidents, and if the licensee has identified and implemented appropriate corrective actions associated with operator workarounds.
These activities constitute completion of one operator workarounds sample as defined in Inspection Procedure 71152-05.
b. Findings
No findings were identified.
4OA5 Other
By letter dated June 16, 2011, Comanche Peak Nuclear Power Plant requested that the NRC review the cross-cutting aspect documented with non-cited violation NCV 05000445/2011007-02; 00500446/2011007-02. The violation was issued for a failure to implement and maintain in effect all provisions of the approved fire protection program and was assigned a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action component P1.a]. The NRC responded by letter dated July 8, 2011 (ADAMS Accession No. ML11192A046). After review of the additional information provided by licensee, the NRC determined that no cross-cutting aspect applied for NCV 05000445/2011007-02; 00500446/2011007-02.

4OA7 Licensee-Identified Violations
The following violations of very low safety significance (Green) were identified by the licensee and are a violation of NRC requirements which meets the criteria of Section 2.3.2 of the NRC Enforcement Policy for being dispositioned as non-cited violations.
.1 Title 10 CFR 50.54(q) requires, in part, that a licensee follow emergency plans which
meet the standards of 50.47(b). Comanche Peak Nuclear Power Plant, Revision 38, Section 13, Radiological Emergency Response Training, requires emergency response organization training as described in Procedure TRA-105, Emergency Preparedness Training. Contrary to the above, from August 24, 2009 to July 13, 2011, the licensee did not follow Section 13 of the station Emergency Plan, Revision 38. Specifically, four on-shift chemistry technicians filled on-shift emergency response organization watch positions without having received initial emergency response organization training required by TRA-105, Emergency Preparedness Training, Revisions 21 to 23. The technicians received emergency response organization continuing training during continuing chemistry department training that allowed them to respond to emergencies.
This finding is of very low safety significance because it is not a risk significant planning standard functional failure or degraded function. The affected chemistry technicians were able to adequately perform emergency response organization duties despite not having completed required initial response training. This issue is documented in the licensees corrective action program as Condition Report CR-2011-007964.
.2 Technical Specification Section 5.4.1.a requires, in part, that written procedures shall be
established, implemented, and maintained covering the applicable procedures
recommended in Appendix A to Regulatory Guide 1.33, February 1978. Regulatory Guide 1.33, Appendix A, Section 7(e) requires, in part, that radiation protection procedures for access control to radiation areas be established, including a radiation work permit system. Radiological Work Permit 2011-0404 implemented this requirement and Task 1 of this permit allowed access to high radiation areas, but required that workers receive authorization to access beneath the grating. Contrary to the above, on September 28, 2011 a radiation worker failed to implement Radiological Work Permit 2011-0404 by failing to receive authorization from radiation protection prior to entry below the grating. The violation is considered to be of very low safety significance because:
- (1) it is not an ALARA planning issue,
- (2) there was no overexposure,
- (3) there was no substantial potential for overexposure, and
- (4) the licensees ability to assess dose was not compromised. The licensee placed the finding into the corrective action program as Condition Report CR-2011-010601.
