SUMMARY
IR 05000382/2014003; 04/01/2014 - 06/30/2014; Waterford Steam Electric Station,
Unit 3; Integrated Inspection Report; Radiological Hazard Assessment and Exposure Controls and Problem Identification and Resolution The inspection activities described in this report were performed between April 1 and June 30, 2014, by the resident inspectors at the site and inspectors from the NRCs Region IV office. Two findings of very low safety significance (Green) are documented in this report.
Both of these findings involved violations 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, Components 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: Occupational Radiation Safety
- Green.
The inspectors reviewed a self-revealing, non-cited violation of Technical Specification 6.12.1 because a worker entered a high radiation area, but was not on a radiation work permit that authorized entry and was not knowledgeable of the dose rates in the area. Specifically, on April 14, 2014, a worker entered shutdown heat exchanger room B, a posted high radiation area during crud burst operations, and received an unanticipated electronic dose rate alarm of 107 millirem per hour. Radiation protection personnel counseled the worker, revoked his access to radiological controlled areas, and documented the occurrence in the corrective action program as Condition Report CR-WF3-2014-01638.
The entry into a high radiation area while not on a radiation work permit that allows entry into high radiation areas and without knowledge of the dose rates in the area is a performance deficiency. The performance deficiency is more than minor and a violation of Technical Specification 6.12.1 because it impacted the program and process attribute (exposure control) of the occupational radiation safety cornerstone and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, the inspectors determined the violation has very low safety significance because: (1) it was not as low as is reasonably achievable (ALARA) finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. This violation has a cross-cutting aspect in the human performance area, associated with an individuals failure to implement appropriate error reduction tools necessary for avoiding complacency by recognizing and planning for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes [H.12].
(Section 2RS1)
Cornerstone: Emergency Preparedness
- Green.
The inspectors identified a non-cited violation of 10 CFR Part 50.54(q)(2) for a failure to maintain the effectiveness of an emergency plan that meets the planning standards of 10 CFR Part 50.47(b). Specifically, the licensee failed to maintain the public address system in a manner that could provide prompt protective action notifications via voice or emergency alarms to all areas and buildings on the plant site. The capability to implement onsite protective actions for its workers is required by 10 CFR Part 50.47(b)(10).
The licensee implemented compensatory measures while the system was being restored.
Based on communications from the licensee on January 14, 2014, signs have been placed on entrances to areas affected by the non-functional public address speakers detailing alternate radio communications protocols that must be used while in the areas. In addition, public address speaker communications were sent out via group pagers and plant radio systems as well to enhance the ability to reach all workers. These compensatory measures have been communicated to their operations staff via written instructions in their daily turnover documentation. The licensee entered the issue into the corrective action program as Condition Report CR-WF3-2013-05860.
The failure to maintain the effectiveness of the means to warn or advise onsite individuals of the range of protective measures consistent with the licensees emergency plan was a performance deficiency. The performance deficiency is more than minor because it is associated with the facilities and equipment attribute of the emergency preparedness cornerstone and it adversely impacted the objective of ensuring that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. In addition, if left uncorrected, continued degradation of the public address system could lead to workers not receiving emergency instructions in a manner timely enough to ensure their safety. Using NRC Inspection Manual Chapter 0609,
Attachment 4, Initial Characterization of Findings; and the corresponding Appendix B,
Emergency Preparedness Significance Determination Process (SDP), the finding was determined to have very low safety significance (Green) because it did not result in a loss of risk-significant planning standard function, a risk-significant planning standard degraded function, or a loss of planning standard function. The finding had a cross-cutting aspect in the evaluation area of problem identification and resolution, associated with thoroughly evaluating issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. From August 2011 to December 4, 2013, as documented by multiple condition reports, there have been many instances of speaker and system component failures that have resulted in fixing failed components only without addressing the underlying conditions causing those failures. None of the failures caused the licensee to question whether they fully understood the reasons for the repetitive failures and whether alternative actions were necessary to correct the causes [P.2]. (Section 4OA2.2)
Licensee-Identified Violations
None.

RADIATION SAFETY
Cornerstones: Public Radiation Safety and Occupational Radiation Safety
2RS1 Radiological Hazard Assessment and Exposure Controls
a. Inspection Scope
The inspectors assessed the licensees performance in assessing the radiological hazards in the workplace associated with licensed activities. The inspectors assessed the licensees implementation of appropriate radiation monitoring and exposure control measures for both individual and collective exposures. The inspectors walked down various portions of the plant and performed independent radiation dose rate measurements. The inspectors interviewed the radiation protection manager, radiation protection supervisors, and radiation workers. The inspectors reviewed licensee performance in the following areas:
- The hazard assessment program, including a review of the licensees 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 radiologically 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 These activities constitute completion of one sample of radiological hazard assessment and exposure controls as defined in Inspection Procedure 71124.01.
b. Findings
Introduction.
The inspectors reviewed a self-revealing, Green, non-cited violation of Technical Specification 6.12.1 that resulted when an individual entered a posted high radiation area without being on a high radiation area radiation work permit and was not knowledgeable of the dose rates.
Description.
On April 14, 2014, a security officer entered shutdown heat exchanger room B, a posted high radiation area during crud burst operations, without having knowledge of the actual radiological conditions. The individual was not on a radiation work permit that authorized entry into high radiation areas. According to licensee records, the individual entered the posted high radiation area twice and received an electronic dosimeter rate alarm of 107 millirem per hour. The individual observed the posted high radiation area and assumed that he was allowed to patrol the area. After hearing the electronic dosimeter alarm, the individual exited the room and when the electronic dosimeter stopped alarming, the guard re-entered the room to proceed with his patrol. When the individual heard the electronic dosimeter alarm, he did not stop and notify radiation protection of the electronic dosimeter alarm. When the individual exited the radiologically controlled area, he did not inform radiation protection of his electronic dosimeter alarm or that the radiologically controlled area access system had given him a red screen, whereby he was given another opportunity to inform radiation protection.
When the individual tried to enter the radiologically controlled area later in the shift, the radiologically controlled area access system would not allow his entry and directed him to the attention of radiation protection.
Analysis.
The entry into a high radiation area while not on a radiation work permit that allows entry into high radiation areas and without knowledge of the dose rates in the area is a performance deficiency. This performance deficiency is more than minor and a violation of Technical Specification 6.12.1 because it impacted the program and process attribute (exposure control) of the occupational radiation safety cornerstone and adversely affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation. Specifically, an individuals entry into a high radiation area without proper knowledge of dose rates and radiological conditions placed the worker at risk for unnecessary radiation exposure. Using Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, and Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, the inspectors determined the violation has very low safety significance (Green)because:
- (1) it was not an as low as is reasonably achievable (ALARA) finding,
- (2) there was no overexposure,
- (3) there was no substantial potential for an overexposure, and
- (4) the ability to assess dose was not compromised. This violation has a cross-cutting aspect in the human performance area associated with an individuals failure to implement appropriate error reduction tools necessary for avoiding complacency by recognizing and planning for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes [H12].
Enforcement.
Technical Specification 6.12.1 states, in part, that each high radiation area in which the intensity of radiation is greater than 100 millirem per hour, but less than 1,000 millirem per hour shall be barricaded and conspicuously posted as a high radiation area and entrance thereto shall be controlled by issuance of a radiation work permit. Technical Specification 6.12.1(b) states, in part, that any individual or group of individuals permitted to enter such areas shall be provided with a radiation monitoring device which continuously integrates the radiation dose rate in the area and alarms when a preset integrated dose is received. Entry into such areas with this monitoring may be made after the dose rate level in the area has been established and personnel have been made knowledgeable of them.
Contrary to the above, on April 14, 2014, an individual entered a high radiation area, but was not on a radiation work permit that authorized entry into high radiation areas and was not knowledgeable of the dose rates in the area. Specifically, a security officer entered the shutdown heat exchanger room B, an established posted high radiation area, and his electronic dosimeter alarmed, measuring a peak dose rate of 107 millirem per hour. The Radiation Protection staff counseled the individual, revoked his access to radiological controlled areas, and documented the occurrence in the corrective action program as Condition Report CR-WF-2014-01638. This violation was of very low safety significance and was entered into the licensees corrective action program as Condition Report CR-WF-2014-01638, this violation is being treated as a non-cited violation, consistent with Section 2.3.2.a of the Enforcement Policy:
NCV 05000382/2014003-01; Failure to Control Entry into a High Radiation Area.

b. Findings
Failure to Maintain Adequate Public Address System to Implement Onsite Protective Actions
Introduction.
The inspectors identified a Green non-cited violation of 10 CFR Part 50.54(q)(2) because the licensee did not maintain the effectiveness of an emergency plan that meets the planning standards of 10 CFR Part 50.47(b).
Specifically, the licensee did not maintain the public address system in a manner that could provide protective action notifications via voice or emergency alarms to all areas and buildings on the plant site. The capability to implement onsite protective actions for its workers is required by 10 CFR Part 50.47(b)(10).
Description.
During the December 4, 2013, biennial exercise, NRC inspectors observed a failure of the public address system to provide audible announcements in the emergency facilities. This failure lasted for about one and one-half hours. Following the exercise, the licensee initiated an investigation into the cause and extent of condition of the failure. During discussion of investigation status between the licensee and the NRC inspectors on December 5, 2013, licensee staff mentioned that there were some public address system speakers that were non-functional prior to the exercise. The inspectors asked if the licensee had evaluated the cumulative effects of the non-functioning speakers (how many, how long they had been non-functioning, and if compensatory measures were put into place) on their ability to provide a range of protective actions for emergency workers and the public in accordance with 10 CFR Part 50.47(b)(10).
The licensee had not evaluated this in the past, so it was included in the scope of their ongoing investigation.
The investigation revealed the following:
- During the December 4, 2013, system failure, the public address system was inaudible in the service building, administration building, central alarm station, west side access, main support building, Emergency Operations Facility, and parts of the reactor auxiliary building and the turbine generator building.
- During the December 4, 2013, system failure, the public address system volume was lowered significantly in areas in the reactor auxiliary building, near the control room envelope; the Technical Support Center; and the Operations Support Center.
- Prior to the exercise, there were areas where the public address system speakers have been non-functional for a minimum of one year and six months. The total speakers affected are 30 out of 477 onsite (approximately 6 percent).
- Since the public address systems installation prior to 1984, the additional loads added to the system have resulted in system power demand during use that has exceeded the installed power amplifiers design capacity. During current public address system use, the demand is 1000 Watts per power amplifier.
The power amplifiers were only designed to supply 800 Watts (Condition Report CR-WF3-2013-05860).
- Changes in the public address system have been made that were not documented in the system engineering drawings. Additional speakers in newer buildings have been added that have not been documented (Condition Reports CR-WF3-2013-05879 and CR-WF3-2013-01823).
Condition reports associated with the public address system were reviewed over the current two-year period (from August 2011 through December 4, 2013). During that time, there were numerous component failures providing evidence that the systems adequacy was not being maintained. Examples include:
- Eight instances involving the receipt of the systems supervisory alarm in the control room, indicating electrical component failures in the system (Condition Reports CR-WF3-2012-02055, CR-WF3-2012-03319, CR-WF3-2012-05959, CR-WF3-2012-07316, CR-WF3-2013-00752, CR-WF3-2013-05506, CR-WF3-2013-05594, and CR-WF3-2013-05751)
- Three failures to function during Emergency Preparedness drills (Condition Reports CR-WF3-2012-03566, CR-WF3-2013-01824, and CR-WF3-2013-05594)
- Two examples of failures during actual site medical events that delayed emergency response (Condition Reports CR-WF3-2012-05959 and CR-WF3-2013-03840)
The licensee developed an engineering proposal in August 2002 to address noted deficiencies in the public address system. In Engineering Request ER-W3-1998-0208-000, dated August 21, 2002, the licensee indicated that the state of the system involved paging trains and the amplifiers operating in overloaded conditions, including the portion of the public address system in the turbine generator building being extremely overloaded. The proposal denotes that the systems amplifier manufacturer did not make the components anymore, there was need to add additional system loads to provide paging to other areas, and the power supply for the system (PDP 3014AB) was fully loaded. In the Design Input Record attachment, it states, The paging amplifiers have been experiencing failure due to load exceeding the capacity of the installed. In addition, the equipment is most probably approaching end of operating life with no replacement models as the original manufacturer is no longer in business.
The licensees plan was to upgrade the public address system, its power supply, and add additional needed loads. Engineering Request ER-W3-2000-0086-000-00 documented the plan to install permanent public address system loads in the construction support building during the same timeframe. Based on the licensees review of these engineering requests documented in Condition Report CR-W3-2013-05860, and confirmed via discussion with licensee staff on February 26, 2013, the plans to modify the system to address its reliability issues was never completed. The licensee added additional permanent loads to the system in the construction support building without addressing the overload and reliability concerns previously identified.
Condition reports reviewed did not include an evaluation of the public address systems functional capability versus all applicable emergency planning requirements.
For example, Condition Reports CR-WF3-2012-02055, CR-WF3-2012-05959, and CR-WF3-2013-00752 stated common language in the Operability section, saying that the system component failures did not require an operability determination or a functional assessment. This was decided because the system was categorized as non-safety-related, so the evaluation was not applicable. While the public address system is nonsafety-related, it does provide the means to make a range of protective actions available to the workers and the public in accordance with 10 CFR Part 50.47(b)(10).
The specific details on how the licensees public address system meets this function are documented in the licensees emergency plan. With no evidence that this functional assessment had been completed at any time, on February 3, 2014, the inspectors asked the licensee how the public address system, with its repeated component failures, was in compliance with the site emergency plan.
The current state of the licensees public address system is not in compliance with their emergency plan. In the Waterford 3 SES Emergency Plan, Revision 044, Section 7.5.1.2, it states, in part, that a malfunction of a power amplifier will only affect 25 percent of the speakers, but in no case will an area or building lose total coverage.
Also, in Section 7.5.3.1, it discusses the function of the fire and station alarms, which transmit their signal via the public address system to the site. These alarms, credited as making up the onsite emergency notification system, are conveyed through paging amplifiers and broadcast through the loudspeaker system covering the entire site.
During the December 4, 2013, exercise, the public address system did not function in multiple entire buildings. In addition, with the record of public address system failures documented in condition reports and the August 2002 engineering request document, this resulted in multiple instances when the credited fire and station alarms would not have been heard throughout the entire plant site had an actual emergency occurred.
Resulting from the functionality issues with the public address system, the licensee is implementing compensatory measures until the system is restored. Based on communications from the licensee on January 14, 2014, signs have been placed on entrances to areas affected by the non-functional public address speakers detailing alternate radio communications protocols that must be used while in the areas. In addition, public address speaker communications will be sent out via group pagers and plant radio systems as well to enhance the ability to reach all workers. These compensatory measures have been communicated to their operations staff via written instructions in their daily turnover documentation.
In summary, during the period from August 2002 to present, the licensee made changes to the public address system that have degraded their ability to use the system to implement a range of protective actions to protect emergency workers onsite, as required by 10 CFR Part 50.47(b)(10). This resulted in failure to maintain emergency plan compliance, which culminated in the failure of the public address system for approximately one and a half hours during the December 4, 2013, biennial emergency preparedness evaluated exercise.
Analysis.
The failure to maintain the effectiveness of the means to warn or advise onsite individuals of the range of protective measures consistent with the licensees emergency plan was a performance deficiency. The performance deficiency is more than minor because it is associated with the facilities and equipment attribute of the emergency preparedness cornerstone and it adversely impacted the objective of ensuring that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. In addition, if left uncorrected, continued degradation of the public address system could lead to workers not receiving emergency instructions in a manner timely enough to ensure their safety. The inspectors performed the significance determination using NRC Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings (issue date: June 19, 2012); and Appendix B, Emergency Preparedness Significance Determination Process (SDP), Attachment 2 (issue date: February 24, 2012), to evaluate the issue. Because this issue dealt with both a percentage of public address speakers not functioning for an extended time period, as well as the long-term degraded condition of public address system components, no significance example fully enveloped the finding being considered within Table 5.10-1 of Appendix B. Therefore, per Section 5.0.1(c) of Appendix B, the finding was compared against the definitions with Appendix B, Attachment 2. The inspectors determined that the finding was of very low safety significance (Green) because it did not result in a loss of risk-significant planning standard function, a risk-significant planning standard degraded function, or a loss of planning standard function.
The finding had a cross-cutting aspect in the evaluation area of problem identification and resolution, associated with thoroughly evaluating issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance.
From August 2011 to December 4, 2013, as documented by multiple condition reports, there have been many instances of speaker and system component failures that have resulted in fixing failed components only without addressing the underlying conditions causing those failures. None of the failures caused the licensee to question whether they fully understood the reasons for the repetitive failures and whether alternative actions were necessary to correct the causes [P.2].
Enforcement.
Title 10 CFR Part 50.54 (q)(2) requires, in part, a licensee to follow and maintain the effectiveness of an emergency plan that meets the requirements in Appendix E to this part and, for nuclear power reactor licensees, the planning standards of 10 CFR 50.47(b). Part 50.47(b)(10) requires licensees to develop a range of protective actions for the plume exposure pathway emergency planning zone (EPZ) for emergency workers and the public. Waterford 3 SES Emergency Plan, Revision 044, establishes the onsite loudspeaker system as the means to satisfy this requirement.
Section 7.5.3.1 of the Plan discusses the function of the fire and station alarms, which transmit their signal via the public address system to the site. These alarms, credited as making up the onsite emergency notification system, are conveyed through paging amplifiers and broadcast through the loudspeaker system covering the entire site.
In addition, Section 7.5.1.2, places a limit on how extensive loudspeaker malfunctions can be and states, in part, that a malfunction of a power amplifier will only affect 25 percent of the speakers, but in no case will an area or building lose total coverage.
Contrary to the above, from August 21, 2002, to December 4, 2013, the licensee failed to maintain the effectiveness of the emergency plan, in particular, with reference to its compliance with 10 CFR Part 50.47(b)(10). Specifically, the licensee failed to maintain the public address system in a manner to ensure no areas or buildings would lose total coverage, nor that the credited fire and station alarms would be conveyed via the public address system to the entire site. The licensee has compensatory measures in place, and entered the issue into the corrective action program in Condition Report CR-W3-2013-05860.
Because the licensee entered the issue into its corrective action program and the finding is of very low safety significance (Green), this violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRCs Enforcement Policy:
NCV 05000382/2014003-02, Failure to Maintain Adequate Public Address System to Implement Onsite Protective Actions.
4OA3 Follow-up of Events and Notices of Enforcement Discretion
(Closed) Licensee Event Report 05000382/2014-002-00, Inadequate Tightening of Starting Air Filter Housing results in Inoperable Train A Emergency Diesel Generator On March 1, 2014, the licensee identified that the filter housing cover on the emergency diesel generator train A starting air filter had unfastened from its base. The emergency diesel generator is started by means of compressed air. The air filter is in the flowpath to deliver compressed air to one bank of the emergency diesel generator. With an air leak at the filter due to the filter housing being loose or not installed, air would likely not be delivered to the corresponding air distributor, and thus one bank of the emergency diesel generator would not receive compressed air to start the emergency diesel. The last successful start of the emergency diesel generator A was on February 27, 2014. It was assumed that the cover became unfastened during that run; therefore, the emergency diesel generator was potentially inoperable for 2 days as a result of this condition. The licensee identified that the actions required by technical specifications for this condition had not been performed. Specifically, test of emergency diesel generator B was not performed within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, and the requirement to demonstrate the operability of the remaining alternating current circuits at least once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or to be in hot shutdown within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> was not performed.
Upon discovery of this condition, the licensee appropriately entered the applicable technical specifications and followed the associated actions. The filter housing was promptly replaced by the operator who discovered the condition, restoring emergency diesel generator A to an operable status. In addition, the licensee verified that the other three filters on emergency diesel generator A and B starting air systems were properly fastened. The inspectors and the licensee reviewed the associated technical manuals and determined that there were not any specified torque values for this component. In the review of this event, no findings or violations of NRC requirements were identified.
These activities constitute completion of one event follow-up sample, as defined in Inspection Procedure 71153.
4OA5 Other Activities
.1 (Closed) URI 05000382/2013005-02 Protective Action Recommendations Under
Conditions of Changing Wind Vectors Not Consistent with Federal Guidance The inspectors identified, during the December 4, 2013, evaluated exercise, an unresolved item related to the adequacy of the licensees guidelines for the choice of protective actions during an emergency in accordance with the requirements of 10 CFR 50.47(b)(10). The issue was identified as an unresolved item because the NRC had not determined whether the licensee had adequately implemented Planning Standard 10 CFR 50.47(b)(10), which states, in part, that guidelines for the choice of protective actions, consistent with Federal Guidance, are developed and in place.
Specifically, the NRC had not determined whether the restrictions on the application of radiological assessments in Procedure EP-002-052, "Protective Action Guidelines,"
Revision 23, Step 5.4.1.1, adequately implement the guidance of Environmental Protection Agency (EPA) document, EPA-400-R-92-001, "Manual of Protective Action Guides and Protective Action for Nuclear Incidents." On June 23, 2014, the licensee provided information indicating that, at the time of the exercised protective action recommendation (PAR), General Emergency conditions continued to exist. The NRC determined that the PAR was appropriate to the circumstances presented in the exercise and that no performance deficiency existed.
.2 Follow Up Inspection for Three or More Severity Level (SL) IV Traditional Enforcement
Violations in the Same Area in a 12-Month Period (IP 92723)
a. Inspection Scope
The NRC performed Inspection Procedure 92723, Follow Up Inspection for Three or More Severity Level IV Traditional Enforcement Violations in the Same Area in a 12-Month Period. The licensee received three Severity Level IV violations in the traditional enforcement area of impeding regulatory process at the end of the 2013 mid-cycle assessment period. The licensee informed the NRC on November 13, 2013, of their readiness to perform this follow-up activity. The NRC reviewed the licensees corrective action documents for each violation and the overall cause analysis for the following items:
- Problem identification
- Cause, extent of condition and extent of cause
- Evaluation of corrective actions
b. Findings and Observations
No findings were identified.
The inspectors determined that the licensee properly identified the problem and causes using a systematic approach. The evaluation adequately addressed the extent of condition and extent of cause. It appears that the corrective actions taken or planned were appropriate to address the causes, and schedules to measure the success of these actions were established.
.3 Follow-up on Traditional Enforcement Actions Including Violations, Deviations,
Confirmatory Action Letters, Confirmatory Orders, and Alternative Dispute Resolution Confirmatory Orders (IP 92702)a. Background On August 24, 2011, the NRC issued a Confirmatory Order (EA-11-096) to Entergy Operations, Inc., and Entergy Nuclear Operations, Inc. (collectively referred to as Entergy). The Confirmatory Order actions were agreed upon by Entergy and the NRC during an alternative dispute resolution session held on July 18, 2011, to resolve NRC concerns regarding an apparent violation of employee protection requirements at the River Bend Station. The actions focused on reorganizing the Quality Control reporting relationships, ensuring adequate training of 10 CFR 50.7, Employee Protection, and performing an effectiveness review of the Employee Concerns Program procedures at all Entergy facilities.
By letter dated August 23, 2012, Entergy notified the NRC of the actions that had been taken in response to the requirements imposed by the Confirmatory Order. Accordingly, during the week of April 29, 2013, NRC staff from the Office of Enforcement and Region IV performed an inspection at the River Bend Station to assess the specific actions identified in Entergys response letter. NRC staff also verified implementation of the remaining actions required to satisfy the conditions set forth in the Confirmatory Order for all Entergy sites. Subsequent to this inspection, NRC staff continued to interact with Entergy regarding the adequacy of the corrective and preventive actions related to the underlying discriminatory issue.
b. Findings and Observations
No findings were identified.
During the follow-up inspection, the NRC staff reviewed Entergys Employee Concerns Program supervisory training and general employee training documents, the relevant lessons learned from the facts of this matter, and the fleet-wide written communication reinforcing Entergys commitment to maintaining a safety-conscious work environment.
The NRC staff also reviewed the General Employee Training and Supervisory Training modules. Based on these reviews, it was determined that these training modules adequately addressed employee protection and included insights from the underlying discriminatory matter. The NRC staff determined that the supervisory training module appeared complete and included case studies as well as the specific elements from the underlying § 50.7, Employee Protection, violation. However, it was noted that although employees receive General Employee Training on an annual basis, Entergy does not require supervisors to take employee protection refresher training on a recurring basis, as a means to reinforce these standards.
Additionally, NRC staff evaluated the results of Entergys effectiveness review of Employee Concerns Program (ECP) enhancements and the associated training that arose from the corrective actions taken to address this matter. Based on the results of this evaluation, it was determined that Entergy had performed the requisite reviews at each station including examination of selected ECP Case Files, Records Retention, Concerned Individual follow-up, and ECP Coordinator training. Within the areas examined, no findings were identified and in general it was determined that Entergy had adequately performed the effectiveness review of ECP procedural enhancements and the ECP training related to this matter.
During the follow-up review of the Quality Control/Quality Assurance reporting relationship, it was determined that Entergys response did not ensure that persons performing the quality assurance function of receipt inspection reported to a management level sufficient to maintain organizational freedom and independence from cost and schedule were maintained. Subsequent to the identification of this performance issue, which affected the implementation of the quality assurance program at all nine Entergy sites, the condition was entered into the licensees corrective action program as Condition Report CR-HQN-2013-00466.
Following the identification of this issue, additional discussions were held between NRC and Entergy to clarify the intent of the settlement agreement and subsequent Confirmatory Order stemming from the earlier alternate dispute resolution mediation.
As a result of these discussions, Entergys Corporate Licensing organization developed a fleet reconciliation plan to modify Entergys Quality Assurance Program Manual to require that individuals performing inspections in accordance with Quality Assurance Program Manual, Section B.12, Inspection, functionally report to the associated manager responsible for Quality Assurance. As described in the corrective actions associated with Condition Report CR-HQN-2013-00466, the affected individuals were those requiring certification in accordance with Quality Assurance Program Manual, Table 1, Regulatory Commitments, Section G, Regulatory Guide 1.58, Revision 1, Qualification of Nuclear Power Plant Inspection, Examination, and Testing Personnel, dated September 1980. In addition to revising the applicable provisions in the Quality Assurance Program Manual, corrective actions were initiated to revise implementing procedures to reflect the change in reporting relationship during the performance of required inspections as well as providing training to the affected individuals. The NRC staff confirmed that the remaining conditions of the Confirmatory Order were adequately addressed.
Based on the above reviews, the NRC determined that Entergy properly implemented the conditions specified in the Confirmatory Order and that the associated actions were adequately implemented.
