SUMMARY OF FINDINGS
IR 05000424/2015003, 05000425/2015003; 07/01/2015 - 09/30/2015; Vogtle Electric
Generating Plant, Units 1 and 2; Licensed Operator Requalification Program and Licensed Operator Performance, Radiological Hazard Assessment and Exposure Controls The report covered a 3-month period of inspection by resident inspectors and regional inspectors. Three findings are documented in this report. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow,
Red) and determined using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP) dated April 29, 2015. The cross-cutting aspects are determined using IMC 0310, Aspects within the Cross-Cutting Areas dated December 4, 2014. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy dated February 4, 2015. The NRCs program for overseeing the safe operations of commercial nuclear power reactors is described in NUREG-1649,
Reactor Oversight Process, Revision 5.
Mitigating Systems Cornerstone
- Green.
An NRC-identified Non-cited Violation (NCV) of 10 CFR 55.49, Integrity of examinations and tests, was identified for the licensees failure to adhere to requirements of NMP-TR-424, License Operator Continuing Training Exam Development, Version 3.1. NMP-TR-424 was the procedure that the licensee used to implement industry standard ACAD 07-001, Guidelines for the Continuing Training of Licensed Personnel. ACAD 07-001 is a methodology which can be used to fulfill 10 CFR 55.59(c), Requalification program requirements and 10 CFR 55.4,
Systems approach to training (SAT). This violation has been entered into the licensees corrective action program (CAP) as condition report (CR) 10115484.
The inspectors determined that the licensees failure to adhere to overlap standards in NMP-TR-424 was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the Human Performance attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective in that the failure to adhere to examination overlap standards adversely affected the quality of the administration of the operating exams.
The finding was determined to be of very low safety significance (Green) because there was no evidence that a licensed operator had actually gained an unfair advantage on an examination required by 10 CFR 55.59. The finding was directly related to the cross-cutting aspect of procedure adherence of the cross-cutting area of Human Performance because the training staff did not follow the guidance for all licensed operators 2014 annual operating exam [H.8]. (Section 1R11)
- Green.
An NRC-identified finding was identified when between 20 and 40 percent of the written examination questions administered to licensed operators during the biennial requalification examination did not meet the requirements of NMP-TR-424,
Licensed Operator Continuing Training Exam Development, and NUREG-1021,
Operator Licensing Examination Standards For Power Reactors, Revision 10.
The inspectors determined that the failure to ensure that biennial written examinations met the qualitative standards for written examinations was a performance deficiency (PD). The PD was more than minor because it was associated with the Human Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that the quality of biennial written examinations potentially impacted the licensees ability to appropriately evaluate licensed operators. The significance of the finding was determined to be Green because between 20 and 40 percent of the questions reviewed did not meet the standard. No cross-cutting aspect was identified that would be considered a contributor to the cause of the finding. (Section 1R11)
Occupational Radiation Safety Cornerstone
- Green.
A self-revealing NCV of Technical Specification (TS) 5.7.1, High Radiation Area, for an unauthorized entry into a high radiation area (HRA). The radiological aspects were not discussed in the pre-job brief, the health physics (HP) technician in containment did not challenge the crew as to whether or not they received their HRA briefing, and the crew did not follow adequate radiological safety practices, such as reading instructions on the HRA posting prior to entry and not leaning against piping.
The licensee entered this issue into the CAP as CR 870060 The entry into a HRA without meeting the entry requirements specified in T.S. 5.7.1 was a performance deficiency. This performance deficiency was more than minor because it was associated with the Occupational Radiation Safety cornerstone attribute of Human Performance and adversely affected the cornerstone objective in that workers who enter HRAs with inadequate knowledge of current radiological conditions could receive unintended occupational exposures. The finding was evaluated using the Occupational Radiation Safety Significance Determination Process and determined to be of very low safety significance (Green). This finding does not involve a cross-cutting aspect because it is not current license performance.
Violations of very low safety significance that were identified by the licensee have been reviewed by the NRC. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.

a. Inspection Scope
Resident Inspector Quarterly Review of Licensed Operator Requalification: The inspectors observed an evaluated simulator scenario administered to an operating crew as part of the annual requalification operating test required by 10 CFR 55.59, Requalification. The inspectors assessed the following:
- licensed operator performance
- the ability of the licensee to administer the scenario and evaluate the operators
- the quality of the post-scenario critique
- simulator performance Resident Inspector Quarterly Review of Licensed Operator Performance: The inspectors observed licensed operator performance in the main control room on September 20, 2015, while a reactor shutdown was being performed on Unit 1. The inspectors assessed the following:
- use of plant procedures
- control board manipulations
- communications between crew members
- use and interpretation of instruments, indications, and alarms
- use of human error prevention techniques
- documentation of activities
- management and supervision Biennial Licensed Operator Requalification Review: The inspectors reviewed documentation, interviewed licensee personnel, and observed the administration of operating tests associated with the licensees operator requalification program. Each of the activities performed by the inspectors was done to assess the effectiveness of the facility licensee in implementing requalification requirements identified in 10 CFR Part 55, Operators Licenses. The evaluations were also performed to determine if the licensee effectively implemented operator requalification guidelines established in NUREG-1021, Operator Licensing Examination Standards for Power Reactors, and Inspection Procedure 71111.11, Licensed Operator Requalification Program. The inspectors also evaluated the licensees simulation facility for adequacy for use in operator licensing examinations using ANSI/ANS-3.5-1985, American National Standard for Nuclear Power Plant Simulators for use in Operator Training and Examination. The inspectors observed two crews during the performance of the operating tests. Documentation reviewed included written examinations, Job Performance Measures (JPMs), simulator scenarios, licensee procedures, on-shift records, simulator modification request records, simulator performance test records, operator feedback records, licensed operator qualification records, remediation plans, watch standing records, and medical records. The records were inspected using the criteria listed in Inspection Procedure 71111.11. Documents reviewed are listed in the
.
b. Findings
.1 NRC Annual Operating Examinations Exceeded Overlap Standards
Introduction:
A Green NRC-identified NCV of 10 CFR 55.49, Integrity of examinations and tests, was identified for the licensees failure to adhere to requirements of NMP-TR-424, License Operator Continuing Training Exam Development, Version 3.1. NMP-TR-424 was the procedure that the licensee used to implement industry standard ACAD 07-001, Guidelines for the Continuing Training of Licensed Personnel. ACAD 07-001 is a methodology which can be used to fulfill 10 CFR 55.59(c), Requalification program requirements and 10 CFR 55.4, Systems approach to training (SAT).
Description:
The inspectors review of the licensees 2014 annual operating examination schedule identified the following examination overlap issues:
- One licensed SRO who failed the JPM portion of the exam was administered a retake exam; however, the retake exam included four of five JPMs that had previously been administered to different licensed operators earlier in the 2014 annual operating exam cycle. Procedure NMP-TR-424, Section 4.3.1.9, required that at least 50% of the JPM exam consist of JPMs that were not used in any other exam in the same exam cycle.
- One licensed RO did not complete the annual operating exam during the scheduled exam cycle due to absence. When the RO returned, the licensees training staff administered two simulator scenarios that had previously been administered to different licensed operators earlier in the annual operating exam cycle. Procedure NMP-TR-424, Section 4.4.1.5, required that at least 50% of each annual Simulator exam consist of exam scenarios that were not previously been used in any other exam set in the same exam cycle.
Analysis:
The inspectors determined that the licensees failure to adhere to overlap standards in NMP-TR-424 was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the Human Performance attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective in that the failure to adhere to examination overlap standards adversely affected the quality of the administration of the operating exams. The inspectors assessed the significance in accordance with Manual Chapter 0609, Significance Determination Process, Appendix I, Licensed Operator Requalification Significance Determination Process (SDP). The finding was related to requalification exam security because it involved test item repetition between requalification examinations administered during different weeks of a training cycle. This finding was determined to be of very low safety significance (Green) because there was no evidence that a licensed operator had actually gained an unfair advantage on an examination required by 10 CFR 55.59. The finding was directly related to the cross-cutting aspect of procedure adherence of the cross-cutting area of Human Performance because the training staff did not follow the guidance for all licensed operators 2014 annual operating exam. [H.8]
Enforcement:
10 CFR 55.49 stated Applicants, licensees, and facility licensees shall not engage in any activity that compromises the integrity of any application, test, or examination required by this part. The integrity of a test or examination is considered compromised if any activity, regardless of intent, affected, or, but for detection, would have affected the equitable and consistent administration of the test or examination.
This includes activities related to the preparation and certification of license applications and all activities related to the preparation, administration, and grading of the tests and examinations required by this part. 10 CFR Part 55 includes 10 CFR 55.59, Requalification, which requires administration of an annual operating exam to all licensed operators. Contrary to the above, the inspectors identified two examples which could have compromised the integrity of any required application, test, or examination during the 2014 licensed operator annual operating examination. NMP-TR-424 was the procedure that the licensee used to implement industry standard ACAD 07-001, Guidelines for the Continuing Training of Licensed Personnel. ACAD 07-001 was a methodology which can be used to fulfill 10 CFR 55.59(c), Requalification program requirements and 10 CFR 55.4, Systems approach to training (SAT). Because this finding is of very low safety significance and has been entered into the licensees corrective action program as CR 10115484, the violation is being treated as a Non-Cited Violation consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000424, 425/2015003-01, Failure to Maintain Requalification Examination Integrity.
.2 Written NRC Biennial Examinations Did Not Meet Qualitative Standards
Introduction:
An NRC-identified finding was identified based on a determination that between 20 and 40 percent of the written examination questions administered to licensed operators during the biennial requalification examination did not meet the requirements of NMP-TR-424, Licensed Operator Continuing Training Exam Development and NUREG-1021, Operator Licensing Examination Standards For Power Reactors, Revision 10.
Description:
The inspectors evaluated the content of two NRC-required biennial written examinations (SRO Written Exam 1 and RO Written Exam 5) that the licensee developed and administered to licensed operators in 2014, to assess if the questions were flawed. The inspectors reviewed a total of 70 questions (35 questions per examination). Seventeen of the 70 questions (approximately 24 percent) were determined to be flawed.
- Six of the flawed questions were two-part questions, where the stem of the question identified a plant condition by name, which matched the name of a site specific procedure, or the name of a specific abnormal/emergency procedure, and the correct answer to one part of the question could be copied from the associated procedure with little mental activity. Consequently, the discrimination validity of the test items was unacceptably compromised since the odds of obtaining the correct answer for the remaining portion of the two-part question, by chance alone, was fifty percent.
As a result, the overall level of difficulty for each of these six test items was 1 using the 1 - 5 (easy - difficult) rating scale (questions in the 2 - 4 range were acceptable).
- Three of the flawed test items were two-part questions, similar to the six flawed questions described above, but the answer to both parts of the question could be copied from the associated procedure with little mental activity (Direct Look-up).
- Eight of the flawed test items contained psychometric flaws such as two or more non-plausible distracters or partially correct answers.
NMP-TR-424, Section 4.2.4, Written Biennial Exams without a Static Exam, required that all test questions shall be free from psychometric errors, shall not be a direct lookup, and adhere to the psychometric attributes stated in NUREG-1021. The inspectors determined that, collectively, these flaws adversely affected the examinations ability to discriminate a competent operator from an operator who was not competent.
Analysis:
The inspectors determined that the failure to ensure that biennial written examinations met the qualitative industry and site standards established for written examinations, specifically defined in NMP-TR-424, was a performance deficiency. The inspectors determined that the PD was more than minor in accordance with IMC 0612, Appendix B, Issue Screening, because it was associated with the Human Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that the quality of biennial written examinations potentially impacted the licensees ability to appropriately evaluate licensed operators. The significance of the finding was evaluated using IMC 0609, Appendix l, "Operator Requalification Human Performance Significance Determination Process (SDP)." Blocks 4 and 5 of IMC-609 Appendix I resulted in a finding of very low safety significance (Green) because between 20 and 40 percent of the questions reviewed did not meet the standard. No cross-cutting aspect was identified that would be considered a contributor to the cause of the finding.
Enforcement:
Enforcement action does not apply because the performance deficiency did not involve a violation of a regulatory requirement. Because this finding does not involve a violation of regulatory requirements and has very low safety significance, it was identified as FIN 05000424, 425/2015003-02, NRC Biennial Written Examinations Did Not Meet Qualitative Standards.
1R12 Maintenance Effectiveness
a. Inspection Scope
The inspectors assessed the licensees treatment of the two issues listed below in order to verify the licensee appropriately addressed equipment problems within the scope of the maintenance rule (10 CFR 50.65, Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants).

b. Findings
No findings were identified.
1R15 Operability Evaluations
a. Inspection Scope
The inspectors selected the four operability determinations or functionality evaluations listed below for review based on the risk-significance of the associated components and systems. The inspectors reviewed the technical adequacy of the determinations to ensure that technical specification operability was properly justified and the components or systems remained capable of performing their design functions. To verify whether components or systems were operable, the inspectors compared the operability and design criteria in the appropriate sections of the technical specification and updated final safety analysis report to the licensees evaluations. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. Additionally, the inspectors reviewed a sample of corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with operability evaluations.
Documents reviewed are listed in the Attachment.
- Unit 1, Immediate determination of operability (IDO) for the train B EDG due to fuel oil lubricity being out of specification, corrective action report (CAR) 258440

1R18 Plant Modifications
a. Inspection Scope
The inspectors verified that the plant modification listed below did not affect the safety functions of important safety systems. The inspectors confirmed the modifications did not degrade the design bases, licensing bases, and performance capability of risk significant structures, systems, and components. The inspectors also verified modifications performed during plant configurations involving increased risk did not place the plant in an unsafe condition. Additionally, the inspectors evaluated whether system operability and availability, configuration control, post-installation test activities, and changes to documents, such as drawings, procedures, and operator training materials, complied with licensee standards and NRC requirements. In addition, the inspectors reviewed a sample of related corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with modifications. Documents reviewed are listed in the Attachment.
- SNC 690467, Temporary alignment configuration of Unit 2 B train CCW to support maintenance on the Unit 2 B train spent fuel pool heat exchanger

RADIATION SAFETY
Cornerstones: Public Radiation Safety, Occupational Radiation Safety
2RS1 Radiological Hazard Assessment and Exposure Controls
a. Inspection Scope
Hazard Assessment and Instructions to workers: During facility tours, the inspectors directly observed labeling of radioactive material and postings for radiation areas, HRAs and airborne radioactivity areas established within the radiologically controlled area (RCA) of the U1 containment, U1 and Unit 2 (U2) auxiliary buildings, and selected storage locations. The inspectors independently measured radiation dose rates or directly observed conduct of licensee radiation surveys for selected RCA areas. The inspectors reviewed survey records for several plant areas including surveys for alpha emitters, hot particles, airborne radioactivity, gamma surveys with a range of dose rate gradients, and pre-job surveys for upcoming tasks. The inspectors also discussed changes to plant operations that could contribute to changing radiological conditions since the last inspection. For selected outage jobs, the inspectors attended pre-job briefings and reviewed radiation work permit (RWP) details to assess communication of radiological control requirements and current radiological conditions to workers.
Hazard Control and Work Practices: The inspectors evaluated access barrier effectiveness for selected U1 and U2 Locked High Radiation Area (LHRA) and Very High Radiation Area (VHRA) locations. Changes to procedural guidance for LHRA and VHRA controls were discussed with HP supervisors. Controls and their implementation for storage of irradiated material within the spent fuel pool were reviewed and discussed in detail. Established radiological controls (including airborne controls) were evaluated for selected U1 refueling outage tasks including reactor head disassembly, reactor head lift, upper internals lift, pressurizer nozzle inspections, and locked high radiation level decontamination and trash movement in U1 containment. In addition, licensee controls for areas where dose rates could change significantly as a result of plant shutdown and refueling operations were reviewed and discussed.
Occupational workers adherence to selected RWPs and HP technician (HPT)proficiency in providing job coverage were evaluated through direct observations and interviews with licensee staff. Electronic dosimeter (ED) alarm set points and worker stay times were evaluated against area radiation survey results reactor head disassembly, reactor head lift, upper internals lift, pressurizer nozzle inspections, and locked high radiation level decontamination and trash movement in U1 containment. ED alarm logs were reviewed and worker response to dose and dose rate alarms during selected work activities was evaluated. For HRA tasks involving significant dose rate gradients, the inspectors evaluated the use and placement of whole body and extremity dosimetry to monitor worker exposure.
Control of Radioactive Material: The inspectors observed surveys of material and personnel being released from the RCA using small article monitor (SAM), personnel contamination monitor (PCM), and portal monitor (PM) instruments. The inspectors reviewed selected calibration records for selected release point survey instruments and discussed equipment sensitivity, alarm setpoints, and release program guidance with licensee staff. The inspectors compared recent 10 Code of Federal Regulations (CFR)
Part 61 results for the Dry Active Waste (DAW) radioactive waste stream with radionuclides used in calibration sources to evaluate the appropriateness and accuracy of release survey instrumentation. The inspectors also reviewed records of leak tests on selected sealed sources and discussed nationally tracked source transactions with licensee staff.
Problem Identification and Resolution: CRs associated with radiological hazard assessment and control were reviewed and assessed. The inspectors evaluated the licensees ability to identify and resolve the issues in accordance with procedures. The inspectors also evaluated the scope of the licensees internal audit program and reviewed recent assessment results.
Radiation protection activities were evaluated against the requirements of Updated Final Safety Analysis Report (UFSAR) Section 12; TS Sections 5.4 and 5.7; 10 CFR Parts 19 and 20; and approved licensee procedures. Licensee programs for monitoring materials and personnel released from the RCA were evaluated against 10 CFR Part 20 and IE Circular 81-07, Control of Radioactively Contaminated Material. Documents reviewed are listed in the Attachment.
b. Findings
Introduction:
A Green, self-revealing, NCV of TS 5.7.1, High Radiation Area, for an unauthorized entry into a HRA.
Description:
On September 23, 2014, during U2 Refueling Outage 17 (2R17), a crew was tasked to remove hangers near Unit 2 Loop 2 Safety Injection Hot Leg Isolation Valve No. 2-1204-X4 on the 171 elevation of containment. This valve was located inside the bioshield in a HRA. The crew was instructed by their craft supervisor to stop by the HP desk after their pre-job brief. The workers interpreted this instruction to check in with the HP desk inside containment by the entrance into the bioshield, instead of the ALARA trailer where a required specific HRA radiological briefing was to be provided.
The workers entered containment and accessed the work area through a HRA-posted swing-gate. Upon leaning against piping in the work area, one of the workers received a dose rate alarm on his ED. Upon receiving the alarm, the crew immediately stopped work and exited the area. The workers ED dose rate alarm setpoint was 150 mrem/hr under RWP 14-2600, a moderate risk RWP for general entry into containment. The highest dose rate seen by the ED was 258.7 mrem/hr. Documented dose rates in the area were 240 mrem/hr on contact and 95 mrem/hr at 30 cm based on a follow-up survey after the ED alarm. A follow-up investigation determined that radiological aspects of the specific job were not discussed in the pre-job brief, the HP technician in containment did not challenge the crew as to whether or not they received their HRA briefing, and the crew did not follow adequate radiological safety practices, such as reading instructions on the HRA posting prior to entry and not leaning against piping.
Analysis:
The inspectors determined that entry into a HRA without meeting the entry requirements specified in T.S. 5.7.1 was a performance deficiency. This finding is more than minor because it is associated with the Occupational Radiation Safety Cornerstone attribute of Human Performance and adversely affects the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Workers who enter HRAs with inadequate knowledge of current radiological conditions could receive unintended occupational exposures. The finding was evaluated using the Occupational Radiation Safety Significance Determination Process (SDP). The finding was not related to ALARA planning, nor did it involve an overexposure or substantial potential for overexposure, and the ability to assess dose was not compromised. Therefore, the inspectors determined the finding to be of very low safety significance (Green). In accordance with IMC 0612, definition 03.15, Present Performance, this finding does not involve a cross-cutting aspect (CCA) because immediate corrective actions were taken, changes have been made, and the performance deficiency occurred over a year ago with no additional HRA boundary violations since then. Corrective actions included a human performance review board, a station clock reset and plant-wide communication for a second HRA violation occurrence within 6 months, crew supervisors to perform at least one observation of pre-job briefs for one of their crews each day, field HP technicians to validate each workers HRA briefing status, crew supervisors to discuss specific radiological expectations during pre-shift meetings in addition to the required specific HRA briefings, and crew supervisors to have access to the radiological survey maps software (RADIS) on their computers to be used in radiological discussions during pre-shift meetings.
Enforcement:
TS 5.7.1, High Radiation Area, requires in part, individuals entering HRAs meet one or more of the following criteria: a) be provided with a radiation monitoring device that continuously indicates radiation dose rate in the area; b) be provided with a radiation monitoring device that 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 device may be made after the dose rate levels in the area have been established and personnel are aware of them or c) be accompanied by an individual qualified in radiation protection procedures with a radiation dose rate monitoring device, who is responsible for providing positive control over the activities within the area and performs periodic radiation surveillance at the frequency specified by Health Physics supervision in the RWP. Contrary to the above, on September 23, 2014, a worker entered a HRA without being made aware of the dose rate levels in the area and not being accompanied by an individual qualified in radiation protection procedures.
The licensee entered this issue into the CAP as CR 870060 and performed follow-up surveys and convening a human performance review board to examine causal factors for the purpose of determining corrective actions. Because this violation was of very low safety significance and it was entered into the licensees CAP, this violation is being treated as an NCV, consistent with the Enforcement Policy: NCV 05000425, 2015003-03, Unauthorized Entry into a High Radiation Area.
2RS6 Radioactive Gaseous and Liquid Effluent Treatment
a. Inspection Scope
Radioactive Effluent Treatment Systems: The inspectors walked-down selected components of the gaseous and liquid radioactive waste (radwaste) processing and effluent discharge systems.

Inspected equipment included radwaste operator panels, storage tanks, resin transfer piping, processing filters and skids in the Radwaste Processing Facility (RPF), and abandoned processing equipment. The inspectors discussed component function, processing system changes, and radwaste program implementation with licensee staff.
The Annual Radioactive Effluent Release Reports (ARERR) for 2012-2014 were reviewed. Current radionuclide waste characterizations for Dry Active Waste (DAW),
Reactor Coolant System (RCS) filters, Spent Fuel Pool (SFP) filters, and RPF Resins were reviewed and discussed with radwaste staff. For DAW and RPF Resins, the inspectors evaluated analyses for hard-to-detect nuclides, reviewed the use of scaling factors, and examined comparison results between licensee waste stream characterizations and outside laboratory data. Waste stream mixing, concentration averaging methodology, and monitoring of changes in isotopic mixtures were evaluated and discussed with radwaste staff.
Radioactive Material Storage: During walk-downs of indoor and outdoor radioactive material storage areas, the inspectors observed the physical condition and labeling of storage containers and the posting of Radioactive Material Areas. The inspectors also reviewed licensee procedural guidance for storage and monitoring of radioactive material. For selected waste liners, the inspectors verified that the licensee maintained an accurate inventory of package contents, and had performed adequate tests to check for buildup of explosive gases and water intrusion.
Transportation: Selected shipping records were reviewed for consistency with licensee procedures and compliance with NRC and Department of Transportation (DOT)regulations. The inspectors reviewed emergency response information, DOT shipping package classification, waste classification, and radiation survey results. In addition, training records for selected individuals who performed radiation surveys, package loading and closure, and characterization of the shipments were reviewed to ensure that they had been trained in accordance with DOT requirements. While onsite, the inspector observed shipment preparation, loading, and final survey of an Excepted Package of Limited Quantity containing Pressurizer Code Safety Valves. There was a lack of other outgoing shipments during the week of inspection.
Problem Identification and Resolution: The inspectors reviewed CRs in the area of radwaste/shipping. The inspectors evaluated the licensees ability to identify and resolve the issues in accordance with procedures.

4OA2 Identification and Resolution of Problems
.1 Routine Review
The inspectors screened items entered into the licensees corrective action program in order to identify repetitive equipment failures or specific human performance issues for follow-up. The inspectors reviewed condition reports, attended screening meetings, or accessed the licensees computerized corrective action database.
.2 Annual Follow-up of Selected Issues
a. Inspection Scope
The inspectors conducted a detailed review of the following condition reports:
- CR 10060388, Unit 1 SI motor inboard and outboard low bearing oil viscosity
- CR 10066747, Nuclear Oversight Action for Improvement (AFI) associated with the stations failure to maintain emergency operating procedures current with the Pressurized Water Reactors Owners Group (PWROG)/Westinghouse Owners Group (WOG) emergency response guidelines (ERGs).
The inspectors evaluated the following attributes of the licensees actions:
- complete and accurate identification of the problem in a timely manner
- evaluation and disposition of operability and reportability issues
- consideration of extent of condition, generic implications, common cause, and previous occurrences
- classification and prioritization of the problem
- identification of root and contributing causes of the problem
- identification of any additional condition reports
- completion of corrective actions in a timely manner Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
4OA3 Event Follow-up
Using Inspection Procedure (IP) 71153, inspectors followed up on the following licensee event report (LER) to evaluate licensee performance related to the events, the accuracy of the LER, and the appropriateness of corrective actions. Inspectors conducted walk-downs of affected equipment, in-office reviews of corrective action, modification, and design documents, and interviewed personnel from the licensees operations, design, and licensing departments. The inspectors evaluated the licensees compliance with its operating license and applicable regulations.
.1 (Closed) Licensee Event Report 05000424/425/2014-001-00, Operation Outside of
Pressure and Temperature Limit Report Curve Required by Technical Specification 3.4.3
a. Inspection Scope
On February 20, 2014, the licensee identified that both units had operated outside the Pressure/Temperature Limit Report (PTLR) curve required by Technical Specification (TS) LCO 3.4.3, Reactor Coolant System (RCS) Pressure and Temperature (P/T)
Limits. during previous refueling outages. The PTLR identifies a lower pressure limit of zero
- (0) pounds per square inch gauge (psig) that is applicable at all times. From October 2003 through May 2013, refueling outages were conducted on each unit where the RCS was placed under a vacuum (negative pressure) to perform fill and vent operations. The licensee determined that the cause for not entering the required action statements for TS 3.4.3 was failure to recognize that a vacuum was not allowed by the TS. Corrective actions to revise the PTLR for Units 1 and 2 to address establishing a negative pressure (vacuum) in the reactor vessel have been completed. The inspectors reviewed this LER and the associated corrective actions and determined this was a minor violation and not subject to formal enforcement action in accordance with the NRCs Enforcement Policy because the negative internal pressures, due to the vacuum refill operations, did not challenge stress margins of the reactor pressure vessel and related components.
b. Findings
No findings were identified.
4OA6 Meetings, Including Exit
Exit Meeting On October 27, 2015, the resident inspectors presented the inspection results to Mr.
Scott Briggs, Site Operation Director, and other members of the licensees staff. The inspectors confirmed that proprietary information was not provided or examined during the inspection.
4OA7 Licensee-Identified Violations
The following violations of very low safety significance (Green) were identified by the licensee and were violations of NRC requirements which met the criteria of the NRC Enforcement Policy, for being dispositioned as Non-Cited Violations.
- Technical Specifications 5.4.1.b, Procedures, required, in part, that written procedures shall be established, implemented, and maintained for the emergency operating procedures (EOPs) required to implement NUREG-0737, Clarification of TMI Action Plan Requirements, and Supplement 1 to NUREG-0737. Contrary to this requirement, as of August 15, 2007, the licensee failed to maintain EOPs required to implement the requirements of NUREG-0737 and NUREG-0737, Supplement 1. The licensee failed to maintain EOP 19100-C, ECA-0.0 Loss of All AC Power, version 39, consistent with revised Pressurized Water Reactor Owners Group/Westinghouse Owners Group emergency response guidelines that restricted the RCS cooldown rate to less than 100 degrees Fahrenheit per hour to prevent thermal shock to the reactor coolant pump (RCP) seals following a loss of all alternating current power (SB) event. The licensee entered this violation into the CAP as CR 10066747 and revised EOP 19100-C consistent with the updated guidance. A bounding detailed risk evaluation was performed by an NRC regional senior risk analyst (SRA) who determined the finding to be of very low risk significance (Green). The dominant result was a grid-related Loss of Offsite Power that then proceeds to an SBO event and RCP seal failure due to thermal shock.
- 10 CFR 55.21, Medical examination, states, in part, that a licensee shall have a medical examination by a physician every two years. Contrary to the above, on March 24, 2015, the licensee identified that a licensed operator did not complete the required biennial NRC medical examination by February 2015, which was the two year due date. The licensed operators requirement to have a medical examination was incorrectly removed from the licensees learning management system (LMS)database when the operator entered the initial license training program to upgrade to a senior operator. The inspectors determined that the violation was not greater than very low safety significance (Green) because the licensed operator was not actively performing licensed duties in the control room. This issue was entered in the licensees corrective action program as CR 10045159.
