SUMMARY OF FINDINGS

Inspection Report 05000341/2015002; 04/01/2015-06/30/2015; Fermi Power Plant, Unit 2; In-Plant Airborne Radioactivity Control and Mitigation. This report covers a 3-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. One Green finding, which had an associated

Non-Cited Violation (NCV) of the U.S. Nuclear Regulatory Commission (NRC) regulations, was identified. The significance of inspection findings is 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," dated April 29, 2015. 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 NRC's Enforcement Policy, dated February 4, 2015. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," dated February 2014.

Cornerstone: Occupational Radiation Safety

Green.

The inspectors identified a finding of very low safety significance and associated Non-Cited Violation of 10 CFR 20.1703(c)(4)(vii) for the licensee's failure to implement and maintain procedures for its Mine Safety Appliance (MSA) Ultralite Self-Contained Breathing Apparatus (SCBA) respirators. The SCBA respirators, in question, were among the population of SCBA units available for use but were not within the overhaul frequency specified by the manufacturer; nor was the overhaul frequency addressed by the licensee's procedure. Immediate corrective actions included the removal from service of those respirators for which the required maintenance was not complete. This has been entered into the licensee's corrective action program as CARD 15-23510,

"CLO - Overdue Rebuild Requirement on Spare Regulators," dated May 19, 2015. In accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, "Issue Screening," the inspectors determined the performance deficiency was of more than minor significance because it was associated with the Program and Process attribute of the Occupational Radiation Safety Cornerstone, and adversely affected the cornerstone objective of ensuring the adequate protection of the workers' health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Specifically, the failure to maintain a program or process that drives the performance of required periodic maintenance could have resulted in the SCBA not performing its intended function. Using IMC 0609, Appendix C, "Occupational Radiation Safety Significance Determination Process," the inspectors determined the finding had a very low safety significance (Green) because the finding: (1) did not involve as-low-as-is-reasonably-achievable planning and controls; (2) did not involve a radiological overexposure; (3) there was not a substantial potential for an overexposure; and (4) there was no compromised ability to assess dose. These SCBAs are scheduled for near term replacement with a newer model. The inspectors reviewed the implementation for the new model and determined that an adequate maintenance program has been established. No cross-cutting aspect was assigned because the performance deficiency was not reflective of current performance. (Section 2RS3)3

REPORT DETAILS

Summary of Plant Status Fermi Power Plant, Unit 2, was shut down at the start of the inspection period to complete maintenance following an automatic reactor scram on March 19. On April 3, the licensee performed a reactor startup and synchronized the unit to the electrical grid on April 4, completing a 15-day forced outage. The unit reached 100 percent power on April 6 and was operated at or near full power during the inspection period with the following exceptions:

• On June 27, the licensee reduced power to about 70 percent to perform a control rod pattern adjustment and main turbine control, stop, and bypass valve testing. The unit was returned to 100 percent power on June 28.

• On June 29, the licensee reduced power to about 80 percent to perform an additional control rod pattern adjustment. The unit was returned to 100 percent power on June

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and Emergency Preparedness

1R01 Adverse Weather Protection

.1 Readiness of Offsite and Alternate AC [Alternating Current] Power Systems

a. Inspection Scope

The inspectors evaluated the licensee's plant features and procedures for operation and continued availability of offsite and alternate AC power systems. The inspectors interviewed plant personnel and reviewed the licensee's communications protocols between the Transmission System Operator (TSO) and the plant to verify the appropriate information was being exchanged when issues arose that could impact the offsite power system. Aspects considered in the inspectors' review included:

• The actions to be taken when notified by the TSO that the post-trip voltage of the offsite power system at the plant will not be acceptable to assure the continued operation of the safety-related loads without transferring to the onsite power supply;

• The compensatory actions identified to be performed if it is not possible to predict the post-trip voltage at the plant for the current grid conditions;

• The required re-assessment of plant risk based on maintenance activities that could affect grid reliability, or the ability of the transmission system to provide offsite power; and

• The required communications between the plant and the TSO when changes at the plant could impact the transmission system, or when the capability of the transmission system to provide adequate offsite power is challenged. During the week of May 18 through 22, the inspectors performed a walkdown of the switchyards to observe the material condition of the offsite power sources and also reviewed the status of outstanding work orders (WOs) to assess whether corrective actions for any degraded conditions were scheduled with the TSO with the appropriate priority. In addition, the inspectors verified problems associated with the availability and reliability of the offsite and alternate AC power systems were entered into the licensee's corrective action program with the appropriate characterization and significance. Selected condition assessment resolution documents (CARDs) were reviewed to verify corrective actions were appropriate and implemented as scheduled. Documents reviewed are listed in the Attachment to this report. This inspection constituted one offsite and alternate AC power systems readiness inspection sample as defined in Inspection Procedure (IP) 71111.01.

• Onsite Storage Facility;

• Auxiliary Building Fifth Floor, Division 1 Control Center Heating, Ventilation, and Air Conditioning (CCHVAC) Room;

• Reactor Building Third Floor, East Side and Standby Liquid Control; and

• Auxiliary Building Third Floor, Division 2 Switchgear Room. The inspectors reviewed these fire areas to assess if the licensee had implemented a Fire Protection Program that adequately controlled combustibles and ignition sources within the plant; effectively maintained fire detection and suppression capability; maintained passive fire protection features in good material condition; and implemented adequate compensatory measures for out-of-service, degraded, or inoperable fire protection equipment, systems, or features in accordance with the licensee's Fire Protection Plan. The inspectors selected fire areas based on their overall contribution to internal fire risk as documented in the plant's Individual Plant Examination of External Events Report with later additional insights, their potential to impact equipment that could initiate or mitigate a plant transient, or their impact on the plant's ability to respond to a security event. The inspectors verified fire hoses and extinguishers were in their designated locations and available for immediate use; fire detectors and sprinklers were unobstructed; transient material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition. In addition, the inspectors verified fire protection related problems were entered into the licensee's corrective action program with the appropriate characterization and significance. Selected CARDs were reviewed to verify corrective actions were appropriate and implemented as scheduled. Documents reviewed are listed in the Attachment to this report. This inspection constituted four quarterly fire protection inspection samples as defined in IP 71111.05AQ.

b. Findings

The inspectors evaluated the conduct of a scheduled licensee emergency drill on May 12 to identify any weaknesses and deficiencies in classification, notification, and protective action recommendation development activities. The drill was planned to be evaluated and was included in the performance indicator data regarding drill and exercise performance. The inspectors observed emergency response operations in the Control Room Simulator, Technical Support Center, and Emergency Operations Facility to determine whether the event classifications, notifications, and protective action recommendations were performed in accordance with procedures. The inspectors also attended the licensee's drill critique to compare any inspector-observed weaknesses with those identified by the licensee's staff in order to evaluate the critique and to verify whether the licensee's staff was properly identifying weaknesses and entering them into the corrective action program. As part of the inspection, the inspectors reviewed the drill package and other documents. Documents reviewed are listed in the Attachment to this report. This inspection constituted one emergency preparedness drill inspection sample as defined in IP 71114.06.

b. Findings

No findings were identified.

2RS3 In-Plant Airborne Radioactivity Control and Mitigation

This inspection constituted one complete sample as defined in IP 71124.03.

.1 Inspection Planning (02.01)

a. Inspection Scope

The inspectors reviewed the plant's UFSAR, to identify areas of the plant designed as potential airborne radiation areas, and any associated ventilation systems or airborne monitoring instrumentation. The instrumentation review included continuous air monitors and particulate-iodine-noble-gas-type instruments used to identify changing airborne radiological conditions such that actions to prevent an overexposure may be taken. The review included an overview of the respiratory protection program and a description of the types of devices used. The inspectors reviewed the UFSAR, TS, and emergency planning documents to identify location and quantity of respiratory protection devices stored for emergency use. The inspectors reviewed the licensee procedures for maintenance, inspection, and use of respiratory protection equipment, including SCBA, as well as procedures for air quality maintenance. The inspectors reviewed any reported performance indicators related to unintended dose resulting from intakes of radioactive material.

b. Findings

No findings were identified.

.2 Engineering Controls (02.02)

a. Inspection Scope

The inspectors reviewed the licensee's use of permanent and temporary ventilation to determine whether the licensee used ventilation systems as part of its engineering controls (in lieu of respiratory protection devices) to control airborne radioactivity. The inspectors reviewed procedural guidance for use of installed plant systems, such as Containment Purge, Spent Fuel Pool Ventilation, and Auxiliary Building Ventilation, and assessed whether the systems were used-to the extent practicable-during high-risk activities (e.g., using containment purge during cavity flood-up). The inspectors selected installed ventilation systems used to mitigate the potential for airborne radioactivity, and evaluated whether the ventilation airflow capacity, flow path (including the alignment of the suction and discharges), and filter/charcoal unit efficiencies, as appropriate, were consistent with maintaining concentrations of airborne radioactivity in work areas below the concentrations of an airborne area to the extent practicable. The inspectors selected temporary ventilation system setups (high-efficiency particulate air (HEPA) / charcoal negative pressure units, down-draft tables, tents, metal "Kelly" buildings, and other enclosures) used to support work in contaminated areas. The inspectors assessed whether the use of these systems is consistent with licensee procedural guidance and the as-low-as-is-reasonably-achievable (ALARA) concept. The inspectors reviewed airborne monitoring protocols by selecting installed systems used to monitor and warn personnel of changing airborne concentrations in the plant and evaluated whether the alarms and setpoints were sufficient to prompt licensee/worker action to ensure doses were maintained within the limits of 10 CFR Part 20 and the ALARA concept. The inspectors assessed whether the licensee had established trigger points (e.g., the Electric Power Research Institute's "Alpha Monitoring Guidelines for Operating Nuclear Power Stations") for evaluating levels of airborne beta-emitting (e.g., plutonium-241) and alpha-emitting radionuclides.

b. Findings

No findings were identified.

.3 Use of Respiratory Protection Devices (02.03)

a. Inspection Scope

For those situations where it is impractical to employ engineering controls to minimize airborne radioactivity, the inspectors assessed whether the licensee provided respiratory protective devices such that occupational doses were ALARA. The inspectors selected work activities where respiratory protection devices were used to limit the intake of radioactive materials, and assessed whether the licensee performed an evaluation concluding that further engineering controls were not practical and that the use of respirators was ALARA. The inspectors also evaluated whether the licensee had established means (such as routine bioassay) to determine if the level of protection (protection factor) provided by the respiratory protection devices during use was at least as good as that assumed in the licensee's work controls and dose assessment. The inspectors assessed whether respiratory protection devices used to limit the intake of radioactive materials were certified by the National Institute for Occupational Safety and Health/Mine Safety and Health Administration or have been approved by the NRC per 10 CFR 20.1703(b). The inspectors selected work activities where respiratory protection devices were used. The inspectors evaluated whether the devices were used consistent with their National Institute for Occupational Safety and Health/Mine Safety and Health Administration certification or any conditions of their NRC approval. The inspectors reviewed records of air testing for supplied-air devices and SCBA bottles to assess whether the air used in these devices met or exceeded Grade D quality. The inspectors reviewed plant breathing air supply systems to determine whether they met the minimum pressure and airflow requirements for the devices in use. The inspectors selected several individuals, qualified to use respiratory protection devices, and assessed whether they had been deemed fit to use the devices by a physician.

The inspectors selected several individuals assigned to wear a respiratory protection device and observed them donning, doffing, and functionally checking the device as appropriate. Through interviews with these individuals, the inspectors evaluated whether they knew how to safely use the device and how to properly respond to any device malfunction or unusual occurrence (loss of power, loss of air, etc.). The inspectors chose multiple respiratory protection devices staged and ready for use in the plant or stocked for issuance for use. The inspectors assessed the physical condition of the device components (mask or hood, harnesses, air lines, regulators, air bottles, etc.) and reviewed records of routine inspection for each. The inspectors selected several of the devices and reviewed records of maintenance on the vital components (e.g., pressure regulators, inhalation/exhalation valves, hose couplings). The inspectors reviewed the respirator vital components maintenance program to ensure on-site personnel assigned to repair the vital components have received the appropriate manufacturer-approved training.

b. Findings

No findings were identified.

.4 SCBA for Emergency Use (02.04)

a. Inspection Scope

Based on the UFSAR, TSs, and emergency operating procedure requirements, the inspectors reviewed the status and surveillance records of SCBAs staged in-plant for use during emergencies. The inspectors reviewed the licensee's capability for refilling and transporting SCBA air bottles to and from the Control Room and Operations Support Center during emergency conditions. The inspectors selected several individuals on the Control Room shift crews and from designated departments currently assigned emergency duties (e.g., on-site search and rescue duties) to assess whether they were trained and qualified in the use of SCBAs (including personal bottle change-out). The inspectors evaluated whether personnel assigned to refill bottles were trained and qualified for that task. The inspectors determined whether appropriate mask sizes and types were available for use (i.e., in-field mask size and type match what were used in fit-testing). The inspectors determined whether on-shift operators had facial hair that would interfere with the sealing of the mask to the face and whether vision correction (e.g., glasses inserts or corrected lenses) was available as appropriate. The inspectors reviewed the past two years of maintenance records for select SCBA units used to support operator activities during accident conditions and designated as "ready for service" to assess whether any maintenance or repairs on any SCBA unit's vital components were performed by an individual, or individuals, certified by the manufacturer of the device to perform the work. The vital components typically are the pressure-demand air regulator and the low-pressure alarm. The inspectors reviewed the on-site maintenance procedures governing vital component work to determine any inconsistencies with the SCBA manufacturer's recommended practices. For those SCBAs designated as "ready for service," the inspectors determined whether the required, periodic air cylinder hydrostatic testing was documented and up-to-date, and the retest air cylinder markings required by the U.S. Department of Transportation were in place.

b. Findings

(1) Failure to Maintain SCBA Components

Introduction:

The inspectors identified a finding of very low safety significance (Green) and Non-Cited Violation of 10 CFR 20.1703, for the licensee's failure to implement and maintain written procedures regarding maintenance for its SCBA respirators.

Description:

The licensee used Mine Safety Appliance (MSA) Ultralite SCBA respirators for the purpose of minimizing the workers' exposure to radioactive materials.

The manufacturer of these devices specified a graded approach to maintenance based on the frequency of usage of the device. The manufacturer specified the respirator regulator be overhauled with a frequency not-to-exceed 15 years when the SCBA was infrequently used. The inspectors reviewed licensee Procedure 65.000.718, "Maintenance and Repair of MSA Respiratory Protection Equipment," Revision 8. This procedure did not contain SCBA regulator overhaul frequency requirements. The inspectors requested information from the licensee regarding the age of the SCBAs in service. This review determined that two regulators, which were among the population of SCBA units available for use, exceeded the 15-year requirement. These two regulators were last overhauled approximately 19 and 21 years ago, respectively. The licensee previously tracked the overhaul schedule by the usage of an informal tracking method. This informal method of tracking ceased during transition from the previous respiratory protection program owner to the current one.

Analysis:

The inspectors determined the failure to implement and maintain procedures for the maintenance of its Mine Safety Appliance (MSA)BA Ultralite SCBA respirators was a performance deficiency, the cause of which was reasonably within the licensee's ability to foresee and correct, and should have been prevented. The issue was not subject to traditional enforcement since the concern did not have a significant safety consequence, did not impact the NRC's ability to perform its regulatory function, and was not willful. The performance deficiency was determined to be of more than minor safety significance in accordance with IMC 0612, Appendix B, "Issue Screening," issued September 7, 2012, because it was associated with the Program and Process attribute of the Occupational Radiation Safety Cornerstone, and adversely affected the cornerstone objective of ensuring the adequate protection of the workers' health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Specifically, the failure to properly maintain the SCBA respirators could lead to degraded components remaining in service, and the use of degraded SCBAs could impair the users such that they could be unable to perform their intended functions. The inspectors also reviewed the guidance in IMC 0612, Appendix E, "Examples of Minor Issues," issued August 11, 2009, and did not find any similar examples. In accordance with IMC 0609, Appendix C, "Occupational Radiation Safety Significance Determination Process," issued August 19, 2008, the inspectors determined the finding had a very low safety significance (Green) because the finding: (1) did not involve ALARA planning and controls; (2) did not involve a radiological overexposure; (3) there was not a substantial potential for an overexposure; and (4) there was no compromised ability to assess dose.

The licensee is replacing its MSA Ultralite SCBAs in the immediate future. The inspectors evaluated the maintenance schedule for the replacement SCBAs and determined it was in accordance with the manufacturer's specifications. This schedule was within the station's formal ongoing maintenance work process. Additionally, the performance deficiency occurred approximately six years ago and was not determined to be reflective of current performance. Thus, a cross-cutting aspect was not assigned.

Enforcement:

10 CFR 20.1073(c)(4)(vii) requires, in part, that the licensee implement and maintain a Respiratory Protection Program that includes written procedures regarding the maintenance for respiratory protection equipment. Procedure 65.000.718, "Maintenance and Repair of MSA Respiratory Protection Equipment," Revision 8, in part, implements the requirements of 10 CFR 20.1703(c)(4)(vii). Contrary to the above, on May 19, 2015, this procedure did not contain SCBA regulator overhaul frequency requirements and the licensee had SCBA respirators available for use that did not have regulators overhauled at the frequency established by the manufacturer and implemented by licensee Procedure 65.000.718, "Maintenance and Repair of MSA Respiratory Protection Equipment." Corrective actions included the immediate removal from service of the applicable SCBA respirators and the establishment of a formal tracking mechanism to ensure all maintenance was performed within the specifications specified by the manufacturer. Since this finding and violation was of very low safety significance and has been entered in the licensee's corrective action program (as CARD 15-23510, "CLO [Crew Learning Opportunity] - Overdue Rebuild Requirements on Spare Regulators," dated May 19, 2015), this violation is being treated as a Non-Cited Violation consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05000341/2015-002-01, Failure to Maintain Self-Contained Breathing Apparatus Components).

.5 Problem Identification and Resolution (02.05)

a. Inspection Scope

The inspectors evaluated whether problems associated with the control and mitigation of in-plant airborne radioactivity were being identified by the licensee at an appropriate threshold and were properly addressed for resolution in the licensee's corrective action program. The inspectors assessed whether the corrective actions were appropriate for a selected sample of problems involving airborne radioactivity and were appropriately documented by the licensee.

b. Findings

No findings were identified.

2RS4 Occupational Dose Assessment

This inspection constituted one complete sample as defined in IP 71124.04.

.1 Inspection Planning (02.01)

a. Inspection Scope

The inspectors reviewed the results of Radiation Protection Program audits related to internal and external dosimetry (e.g., licensee's quality assurance audits, self-assessments, or other independent audits) to gain insights into overall licensee performance in the area of dose assessment and focus the inspection activities consistent with the principle of "smart sampling." The inspectors reviewed the most recent National Voluntary Laboratory Accreditation Program accreditation report on the vendor's most recent results to determine the status of the contractor's accreditation. A review was conducted of the licensee procedures associated with dosimetry operations, including issuance/use of external dosimetry (routine, multi-badging, extremity, neutron, etc.), assessment of internal dose (operation of whole body counter, assignment of dose based on derived air concentration-hours, urinalysis, etc.), and evaluation of and dose assessment for radiological incidents (distributed contamination, hot particles, loss of dosimetry, etc.). The inspectors evaluated whether the licensee had established procedural requirements for determining when external and internal dosimetry was required.

b. Findings

No findings were identified.

.2 External Dosimetry (02.02)

a. Inspection Scope

The inspectors evaluated whether the licensee's dosimetry vendor was National Voluntary Laboratory Accreditation Program accredited and if the approved irradiation test categories for each type of personnel dosimeter used were consistent with the types and energies of the radiation present and the way the dosimeter was being used (e.g., to measure deep dose equivalent, shallow dose equivalent, or lens dose equivalent). The inspectors evaluated the onsite storage of dosimeters before their issuance, during use, and before processing/reading. The inspectors also reviewed the guidance provided to radiation workers with respect to care and storage of dosimeters. The licensee does not use non-National Voluntary Laboratory Accreditation Program accredited passive dosimeters. The inspectors assessed the use of active dosimeters (electronic personal dosimeters) to determine if the licensee used a "correction factor" to address the response of the electronic personal dosimeter as compared to the passive dosimeter for situations when the electronic personal dosimeter had to be used to assign dose. The inspectors also assessed whether the correction factor was based on sound technical principles. The inspectors reviewed dosimetry occurrence reports or corrective action program documents for adverse trends related to electronic personal dosimeters, such as interference from electromagnetic frequency, dropping or bumping, failure to hear alarms, etc. The inspectors assessed whether the licensee had identified any trends and implemented appropriate corrective actions.

b. Findings

No findings were identified.

.3 Internal Dosimetry (02.03) Routine Bioassay (In-Vivo)

a. Inspection Scope

The inspectors reviewed procedures used to assess the dose from internally deposited nuclides using whole body counting equipment. The inspectors evaluated whether the procedures addressed methods for differentiating between internal and external contamination, the release of contaminated individuals, and the route of intake and the assignment of dose. The inspectors reviewed the whole body count process to determine if the frequency of measurements was consistent with the biological half-life of the nuclides available for intake. The inspectors reviewed the licensee's evaluation for use of its portal radiation monitors as a passive monitoring system to determine if instrument minimum detectable activities were adequate to determine the potential for internally deposited radionuclides sufficient to prompt additional investigation. The inspectors selected several whole body counts and evaluated whether the counting system used had sufficient counting time/low background to ensure appropriate sensitivity for the potential radionuclides of interest. The inspectors reviewed the radionuclide library used for the count system to determine its appropriateness. The inspectors evaluated whether any anomalous count peaks/nuclides indicated in each output spectra received appropriate disposition. The inspector's reviewed the licensee's 10 CFR Part 61 data analyses to determine whether the nuclide libraries included appropriate gamma-emitting nuclides. The inspectors evaluated how the licensee accounted for hard-to-detect nuclides in the dose assessment.

b. Findings

No findings were identified.

Special Bioassay (In-Vitro)

a. Inspection Scope

There were no internal dose assessments obtained using in-vitro monitoring for the inspectors to review. The inspectors reviewed and assessed the adequacy of the licensee's program for in-vitro monitoring (i.e., urinalysis and fecal analysis) of radionuclides (tritium, fission products, and activation products), including collection and storage of samples.

The inspectors reviewed the vendor laboratory quality assurance program and assessed whether the laboratory participated in an industry-recognized cross-check program, including whether out-of-tolerance results were resolved appropriately.

b. Findings

No findings were identified.

Internal Dose Assessment - Airborne Monitoring

a. Inspection Scope

The inspectors reviewed the licensee's program for airborne radioactivity assessment and dose assessment, as applicable, based on airborne monitoring and calculations of derived air concentration. The inspectors determined whether flow rates and collection times for air sampling equipment were adequate to allow lower limits of detection to be obtained. The inspectors also reviewed the adequacy of procedural guidance to assess internal dose if respiratory protection was used. The licensee had not performed dose assessments using airborne/derived air concentration monitoring since the last inspection.

b. Findings

No findings were identified. Internal Dose Assessment - Whole Body Count Analyses

a. Inspection Scope

The inspectors reviewed several dose assessments performed by the licensee using the results of whole body count analyses. The inspectors determined whether affected personnel were properly monitored with calibrated equipment and that internal exposures were assessed consistent with the licensee procedures.

b. Findings

No findings were identified.

.4 Special Dosimetric Situations (02.04) Declared Pregnant Workers

a. Inspection Scope

The inspectors assessed whether the licensee informed workers, as appropriate, of the risks of radiation exposure to the embryo/fetus, the regulatory aspects of declaring a pregnancy, and the specific process to be used for (voluntarily) declaring a pregnancy. The inspectors selected individuals who had declared pregnancy during the current assessment period and evaluated whether the licensee's radiological monitoring program (internal and external) for declared pregnant workers was technically adequate to assess the dose to the embryo/fetus. The inspectors reviewed exposure results and monitoring controls employed by the licensee and with respect to the requirements of 10 CFR Part 20.

b. Findings

No findings were identified. Dosimeter Placement and Assessment of Effective Dose Equivalent for External Exposures

a. Inspection Scope

The inspectors reviewed the licensee's methodology for monitoring external dose in non-uniform radiation fields or where large dose gradients existed. The inspectors evaluated the licensee's criteria for determining when alternate monitoring, such as use of multi-badging, was to be implemented. The inspectors reviewed dose assessments performed using multi-badging to evaluate whether the assessment was performed consistently with licensee procedures and dosimetric standards.

b. Findings

No findings were identified.

Shallow Dose Equivalent

a. Inspection Scope

The inspectors reviewed shallow dose equivalent dose assessments for adequacy. The inspectors evaluated the licensee's method (e.g., VARSKIN or similar code) for calculating shallow dose equivalent from distributed skin contamination or discrete radioactive particles.

b. Findings

No findings were identified.

Neutron Dose Assessment

a. Inspection Scope

The inspectors evaluated the licensee's neutron dosimetry program, including dosimeter types and/or survey instrumentation. The inspectors reviewed neutron exposure situations (e.g., independent spent fuel storage installation operations or at-power containment entries) and assessed whether:

(a) dosimetry and/or instrumentation was appropriate for the expected neutron spectra; (b) there was sufficient sensitivity for low dose and/or dose rate measurement; and (c) neutron dosimetry was properly calibrated. The inspectors also assessed whether interference by gamma radiation had been accounted for in the calibration and whether time and motion evaluations were representative of actual neutron exposure events, as applicable.

b. Findings

No findings were identified.

Assigning Dose of Record

a. Inspection Scope

For the special dosimetric situations reviewed in this section, the inspectors assessed how the licensee assigned dose of record for total effective dose equivalent, shallow dose equivalent, and lens dose equivalent. This included an assessment of external and internal monitoring results, supplementary information on individual exposures (e.g., radiation incident investigation reports and skin contamination reports), and radiation surveys and/or air monitoring results when dosimetry was based on these techniques.

b. Findings

No findings were identified.

.5 Problem Identification and Resolution (02.05)

a. Inspection Scope

The inspectors assessed whether problems associated with occupational dose assessment were being identified by the licensee at an appropriate threshold and were properly addressed for resolution in the licensee's corrective action program. The inspectors assessed the appropriateness of the corrective actions for a selected sample of problems documented by the licensee involving occupational dose assessment.

b. Findings

No findings were identified.

4OA1 Performance Indicator Verification

.1 Mitigating Systems Performance Index (MSPI) - High Pressure Injection Systems

a. Inspection Scope

The inspectors reviewed a sample of plant records and data against the reported MSPI - High Pressure Injection Systems Performance Indicator. To determine the accuracy of the performance indicator data reported, performance indicator definitions and guidance contained in Nuclear Energy Institute (NEI) 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7, was used. The inspectors reviewed the MSPI derivation reports, Control Room logs, Maintenance Rule database, Licensee Event Reports (LERs), and maintenance and test data from April 2014 through March 2015 to validate the accuracy of the performance indicator data reported. The inspectors reviewed the MSPI component risk coefficient to determine if it had changed by more than 25 percent since the previous inspection, and if so, that the change was in accordance with applicable NEI guidance. The inspectors also reviewed the licensee's corrective action program database to determine if any problems had been identified with the performance indicator data collected or transmitted for this performance indicator. Documents reviewed are listed in the Attachment to this report. This inspection constituted one MSPI - High Pressure Injection Systems Performance Indicator verification inspection sample as defined in IP 71151.

b. Findings

No findings were identified.

.2 MSPI - AC Power System

a. Inspection Scope

The inspectors reviewed a sample of plant records and data against the reported MSPI - Emergency AC Power System Performance Indicator. To determine the accuracy of the performance indicator data reported, performance indicator definitions and guidance contained in NEI 99-02, "Regulatory Assessment Performance Indicator Guideline,"

Revision 7, was used. The inspectors reviewed the MSPI derivation reports, Control Room logs, Maintenance Rule database, LERs, and maintenance and test data from July 2014 through March 2015 to validate the accuracy of the performance indicator data reported. The inspectors reviewed the MSPI component risk coefficient to determine if it had changed by more than 25 percent since the previous inspection, and if so, that the change was in accordance with applicable NEI guidance. The inspectors also reviewed the licensee's corrective action program database to determine if any problems had been identified with the performance indicator data collected or transmitted for this performance indicator. Documents reviewed are listed in the Attachment to this report. This inspection constituted one MSPI - Emergency AC Power System Performance Indicator verification inspection sample as defined in IP 71151.

b. Findings

No findings were identified.

.3 RCS Leakage

a. Inspection Scope

The inspectors verified the RCS Leakage Performance Indicator. The inspectors reviewed the licensee's RCS leakage tracking surveillance test data from April 2014 through March 2015 to validate the accuracy of the licensee's submittals. To determine the accuracy of the performance indicator data reported during this period, performance indicator definitions and guidance contained in NEI 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 7, was used. The inspectors also reviewed the licensee's corrective action program database to determine if any problems had been identified with the performance indicator data collected or transmitted for this performance indicator. Documents reviewed are listed in the Attachment to this report. This inspection constituted one RCS Leakage Performance Indicator verification inspection sample as defined in IP 71151.

b. Findings

No findings were identified.

4OA2 Identification and Resolution of Problems

.1 Routine Review of Identification and Resolution of Problems

a. Inspection Scope

As discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify they were being entered into the licensee's corrective action program at an appropriate threshold, adequate attention was being given to timely corrective actions, and adverse trends were identified and addressed. Some minor issues were entered into the licensee's corrective action program as a result of the inspectors' observations; however, they are not discussed in this report.

This inspection was not considered to be an inspection sample as defined in IP 71152.

b. Findings

No findings were identified.

.2 Annual In-depth Review Samples

a. Inspection Scope

The inspectors selected the following issues for in-depth review:

• CARD 14-21815, Human Performance Issues Involving Cycle 16 Refueling Outage (RF16) Refueling Activities; and

• CARD 14-22848, Refueling Bridge Equipment Reliability Issues. As appropriate, the inspectors verified the following attributes during their review of the licensee's corrective actions for the above CARDs and other related CARDs:

• complete and accurate identification of the problem in a timely manner commensurate with its safety significance and ease of discovery;

• consideration of the extent of condition, generic implications, common cause, and previous occurrences;

• evaluation and disposition of operability/functionality/reportability issues;

• classification and prioritization of the resolution of the problem commensurate with safety significance;

• identification of the root and contributing causes of the problem; and

• identification of corrective actions, which were appropriately focused to correct the problem. The inspectors discussed the corrective actions and associated evaluations with licensee personnel. Documents reviewed are listed in the Attachment to this report.

This inspection constituted two annual in-depth review inspection samples as defined in IP 71152.

b. Findings and Observations

No findings were identified.

4OA3 Follow-up of Events and Notices of Enforcement Discretion

.1 (Closed) LER 05000341/2015-001-00, Secondary Containment Declared Inoperable after Loss of Reactor Building Ventilation from Freeze Protection Actuation (Closed) LER 05000341/2015-001-01, Secondary Containment Declared Inoperable after Loss of Reactor Building Ventilation from Freeze Protection Actuation, Supplement 1 On February 19, the nonsafety-related RBHVAC system tripped during operation, causing secondary containment pressure to momentarily exceed the required limit

specified in TS 3.6.4.1, "Secondary Containment," of greater than or equal to

-0.125 inches water gauge. Secondary containment pressure was restored by Control Room operators manually starting the Standby Gas Treatment system. At the time of the trip, outside air temperature was -1 degree Fahrenheit and the nonsafety-related RBHVAC system tripped due to a freeze-stat actuation. The freeze-stat is a low temperature switch installed to protect heating coils in the ventilation duct from freezing.

There is no automatic start of the safety-related Standby Gas Treatment system unless there is a secondary containment isolation actuation. Secondary containment pressure briefly degraded to less than -0.125 inches water gauge for a second time while operators were attempting to restore the RBHVAC system to operation. The licensee completed an 8-hour notification call (Event Notification 50831) on February 19 to report the inoperable secondary containment as required by 10 CFR 50.72(b)(3)(v)(C) as an event or condition, that at the time of discovery, could have prevented the fulfillment of a safety function needed to control the release of radioactive material. The licensee submitted LER 05000341/2015-001-00 to report this event in accordance with 10 CFR 50.73(a)(2)(v)(C) as an event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to control the release of radioactive material. The licensee subsequently supplemented the original LER to correct a minor technical error in the original report. The inspectors reviewed the licensee's cause evaluation for the RBHVAC system trip. The cause was determined to be a freeze-stat actuation on low temperature for the "H" heating coil. The licensee had had multiple freeze-stat trips for the "H" heating coil during the winter months. Engineers examined the "H" heating coil and identified the material deviated from the original design, which resulted in a lower rate of heat transfer. The "H" heating coil was replaced in November 2011 with one made from aluminum.

The original design was copper. The licensee initiated a corrective action to replace the heating coil with original design specification material prior to the next winter season.

The inspectors did not identify any significant safety issue not addressed in the licensee's cause evaluation.

The inspectors concluded there was no finding associated with this event since the performance issue was determined to be of minor safety significance. Although the secondary containment was declared inoperable due to briefly exceeding the TS value for secondary containment vacuum, the structural integrity of the secondary containment was not degraded at the time. Upon receipt of an accident signal, the Standby Gas Treatment system would have automatically started and restored secondary containment vacuum to within the bounding UFSAR Chapter 15 analyses. The accident analysis for a loss-of-coolant-accident does not assume secondary containment is under vacuum throughout the duration of an accident and contains conservative leakage assumptions to bound the effects of a postulated ground level release. No violation of regulatory requirements was identified because the RBHVAC system is not safety related. LERs 05000341/2015-001-00 and 05000341/2015-001-01 are closed. This inspection constituted one event follow-up inspection sample as defined in IP 71153.

.2 (Closed) LER 05000341/2015-002-00, Loss of Both Divisions of the Residual Heat Removal Low Pressure Coolant Injection Functions Due to 480-Volt Swing Bus Inoperable On March 9, while performing a scheduled surveillance test of the automatic transfer (or throw over) of 480-volt bus 72CF, the automatic transfer feature failed.

This resulted in inoperability of both Low Pressure Coolant Injection (LPCI) subsystems. As required by TS 3.5.1 Condition K, the licensee entered TS 3.0.3, requiring entry into Mode 2 within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. Accordingly, the licensee commenced a reactor shutdown at 4:15 p.m. and initiated maintenance to correct the problem. Reactor operators stabilized reactor power at about 81.5 percent when it appeared a resolution of the problem would allow exiting TS 3.5.1 Condition K and TS 3.0.3. After completing corrective maintenance and returning both LPCI subsystems to an operable status to satisfy the TS requirements at 10:11 p.m., the licensee returned the reactor to 100 percent power at 11:59 p.m. The licensee completed a 4-hour notification call (Event Notification 50874) on March 9 to report the initiation of a TS-required plant shutdown under 10 CFR 50.72(b)(2)(i).

The licensee also reported the unplanned inoperability of both LPCI subsystems (8-hour notification requirement) under 10 CFR 50.72(b)(3)(v)(D) as an event or condition that, at the time of discovery, could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident. The licensee submitted LER 05000341/2015-002-00 to report this event in accordance with 10 CFR 50.73(a)(2)(v)(D) as an event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident and 10 CFR 50.73(a)(2)(vii) as any event where a single cause or condition caused two independent trains to become inoperable in a single system designed to mitigate the consequences of an accident. The inspectors reviewed the licensee's apparent cause and equipment apparent cause evaluations for the failure of the 72CF automatic transfer circuit. The apparent cause was determined to be a buildup of tarnish on an auxiliary relay contact, which caused the contact to remain electrically opened when it should have been closed. The inspectors did not identify any significant safety issue neglected from the licensee's apparent cause evaluations. The licensee replaced the auxiliary contact and initiated a preventive maintenance task to cycle the 72CF auxiliary contacts under load or to replace them periodically. The inspectors concluded there was no performance deficiency associated with this event since the failure was not reasonably within the licensee's ability to foresee and correct. Although generic industry guidance existed with recommended frequencies for electro-mechanical relay cleaning and inspection, the component was about 30 years old, had no history of failures, and no specific preventive maintenance activity existed for cleaning or replacing it. LER 05000341/2015-002-00 is closed. This inspection constituted one event follow-up inspection sample as defined in IP 71153.
