On October 4, with Fermi 2 in Mode 5 during the refueling outage, the licensee inadvertently entered an OPDRV condition without an operable secondary containment. An OPDRV is an activity that could result in the draining or siphoning of the reactor vessel water level below the top of the fuel, without crediting the use of mitigating measures to terminate the uncovering of fuel. Secondary containment is required by TS 3.6.4.1 to be operable during an OPDRV to protect against untreated fission product release if the reactor pressure vessel water level drops and uncovers irradiated fuel since the RCS and primary containment boundaries are open during Mode 5 activities. If secondary containment is inoperable during an OPDRV, the TS requires the licensee to initiate actions to suspend the OPDRV immediately. Inasmuch as TS 3.0.4 requires the Limiting Condition for Operation of TS 3.6.4.1 to be satisfied prior to entering an OPDRV condition, entering the OPDRV without establishing secondary containment integrity was considered a condition prohibited by the plant's TS. During the refueling outage, plant operators were isolating a reactor recirculation pump seal flow switch and rotameter for replacement. Shortly after the reactor recirculation pump seal cavity drain valves were opened to depressurize and drain the seal cavity, control room operators identified a lowering SFP skimmer surge tank level and an increase in Drywell floor drain sump level, which indicated a LOI from the RCS. | On October 4, with Fermi 2 in Mode 5 during the refueling outage, the licensee inadvertently entered an OPDRV condition without an operable secondary containment.

Operators subsequently isolated the reactor recirculation pump seal cavity by closing the drain valves and successfully terminated t he OPDRV. The reactor recirculation pump seal drain flow was approximately 12 gallons-per-minute and lasted about 84 minutes. The event occurred with the reactor cavity filled and SFP gates removed. Reactor cavity water level and SFP water level remained constant during the event. The inspectors reviewed the licensee's apparent cause evaluation for the event and concurred with its conclusions. The direct cause was attributed to inadequate self-checking by the operators who prepared and reviewed the system tagout configuration for the maintenance because they did not include closing the reactor recirculation pump suction and discharge isolation valves, which resulted in the reactor recirculation pump and loop piping being in direct communication with the reactor vessel during draining. The apparent cause was determined to be inadequate identification of OPDRV conditions during refueling outage preparations. Those conditions that drain systems that interface with the reactor vessel were not identified and reviewed as part of the Operations Outage Challenge Meetings or the Outage Nuclear Safety Review Meetings conducted by the Outage Review Team in accordance with licensee administrative requirements to ensure OPDRV conditions did not exist, including boundary identification and positive controls. The NRC issued Enforcement Guidance Memorandum (EGM) 11-003, Revision 2, on December 13, 2013, to provide guidance on dispositioning boiling water reactor (BWR)licensee non-compliance with TS containment requirements during OPDRV operations. The NRC considered enforcement discretion related to secondary containment inoperability during Mode 5, OPDRV activities to be appropriate as long as the licensee had taken the following interim actions: | Operators subsequently isolated the reactor recirculation pump seal cavity by closing the drain valves and successfully terminated t he OPDRV.

SUMMARY
Inspection Report 05000341/2015004; 10/01/2015-12/31/2015; Fermi Power Plant, Unit 2; Refueling and Other Outage Activities. This report covers a 3-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors. One Green finding, with 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.
NRC-Identified
and Self-Revealed Findings
Cornerstone: Initiating Events
- Green.
A finding of very low safety significance with an associated non-cited violation of Technical Specification (TS) 3.0.4 was self-revealed on October 4, 2015, when the licensee inadvertently entered an operation with the potential to drain the reactor vessel (OPDRV) condition while in Mode 5 (refueling) without an operable secondary containment. The licensee failed to provide adequate configuration control of reactor recirculation system boundary isolation valves while establishing conditions to support maintenance during the Cycle 17 refueling outage. As an immediate corrective action, the licensee terminated the OPDRV and restored compliance with the TS by closing recirculation pump seal cavity drain valves to isolate the drain path. In addition, the licensee reviewed all remaining refueling outage system tagouts that interfaced with the reactor vessel to ensure appropriate configuration controls were established to prevent impacting reactor vessel water level, initiated actions to make procedure changes to improve its processes for review of system tagouts for conditions that drain systems that interface with the reactor vessel, and communicated lessons learned from this event with plant operators. The finding was of more than minor safety significance because it was associated with the Configuration Control and Human Performance attributes of the Initiating Events
Cornerstone and adversely affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown, as well as power operations. Specifically, the system tagout error resulted in an inadvertent and uncontrolled loss of reactor coolant system inventory. The finding was determined to be a licensee performance deficiency of very low safety significance during a detailed Significance Determination Process review since the delta core damage frequency was determined to be less than 1.0E-7/year. The inspectors concluded this finding affected the cross-cutting area of human performance and the cross-cutting aspect of avoiding complacency. The cause of the event was primarily attributed to a failure to properly use human error reduction techniques, specifically inadequate self-checking by the operator s who prepared and reviewed the system tagout configuration for the maintenance, as well as inadequate identification of OPDRV conditions during refueling outage preparations. [H.12] (Section 1R20.1)3
Licensee-Identified Violations
Cornerstone: Occupational Radiation Safety A violation of very low safety significance that was identified by the licensee has been reviewed by the inspectors.
Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. The violation and corrective action tracking number are listed in Section 4OA7 of this report.

REPORT DETAILS
Summary of Plant Status Fermi Power Plant, Unit 2, was shut down for the Cycle 17 refueling outage (F2RF17) at the beginning of the inspection period. On November 25, 2015, the licensee performed a reactor startup and synchronized the unit to the electrical grid on November 29, 2015, completing a 64-day refueling outage. The unit reached 100 percent power on December 1, 2015. The unit was operated at or near 100 percent power during the remainder of the inspection period with the following exceptions:
- On December 2, 2015, the licensee reduced power to about 80 percent to perform a control rod pattern adjustment. The unit was returned to 100 percent later that day.
- On December 9, 2015, the licensee reduced power to about 85 percent to perform data collection for reactor recirculation pump flow adjustments and to perform a control rod pattern adjustment. The unit was returned to 100 percent later that day.
- On December 12, 2015, the licensee reduced power to about 60 percent to set mechanical limits for the reactor recirculation pump motor generator sets and perform a control rod pattern adjustment. The unit was returned to 100 percent later that day.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and Emergency Preparedness
1R01 Adverse Weather Protection
.1 Winter Seasonal Readiness Preparations
a. Inspection Scope
The inspectors conducted a review of the licensee's preparations for winter conditions to verify the plant's design features and implementation of procedures were sufficient to protect mitigating systems from the effects of adverse weather. Documentation for
selected risk-significant systems was revi ewed to ensure these systems would remain functional when challenged by inclement weather. During the inspection, the inspectors focused on plant specific design features and the licensee's procedures used to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the Updated Final Safety Analysis Report (UFSAR) and performance requirements for systems selected for inspection, and verified operator actions were appropriate as specified by plant specific procedures. Cold weather protection, such as heat tracing and area heaters, was verified to be in operation where applicable. The inspectors'
reviews focused specifically on the following plant systems due to their risk significance or susceptibility to cold weather problems:
- Emergency equipment service water (EESW). The inspectors also verified adverse weather protection problems 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 winter seasonal readiness preparation inspection sample as defined in Inspection Procedure (IP) 71111.01.
b. Findings
No findings were identified.
1R04 Equipment Alignment
.1 Quarterly Partial System Walkdowns
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems:
- Division 2 residual heat removal (RHR) (standby alignment for shutdown cooling operation during operation of Division 1 RHR for shutdown cooling);
- Reactor core isolation cooling (single train risk-significant system); and
- Standby liquid control (SLC). The inspectors selected these systems based on their risk significance relative to the Reactor Safety cornerstones. The inspectors reviewed operating procedures, system diagrams, TS requirements, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and were available. The inspectors observed operating parameters and examined the material condition of the equipment to verify there were no obvious deficiencies. In addition, the inspectors verified problems associated with plant equipment alignment 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 three partial system walkdown inspection samples as defined in IP 71111.04.
b. Findings
No findings were identified.
1R05 Fire Protection
.1 Routine Resident Inspector Tours
a. Inspection Scope
The inspectors conducted fire protection walkdowns focusing on the availability, accessibility, and condition of firefighting equipment in the following risk-significant plant areas:
- Reactor building second floor, south side;
- Turbine building second floor, steam tunnel;
- Drywell;
- Turbine building second floor, 3/4/5 north feedwater heater room;
- Turbine building second floor, 3/4/5 south feedwater heater room; and
- Reactor water clean-up heat exchanger and pump rooms. 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 problems associated with plant fire protection 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 six quarterly fire protection inspection samples as defined in IP 71111.05AQ.
b. Findings
No findings were identified.
1R06 Flooding
.1 Underground Cable Vaults
a. Inspection Scope
The inspectors selected for examination underground bunkers/manholes subject to flooding that contained cables whose failure could disable safety-related and/or risk-significant equipment. The inspectors determined the cables were not submerged, splices were intact, and appropriate cable support structures were in place. In those
areas where dewatering devices were used, such as a sump pump, the device was functional and level alarm circuits were set appropriately to ensure the cables would not be submerged. In those areas without dewatering devices, the inspectors verified adequate drainage of the area was available or the cables were qualified for submergence conditions. The inspectors performed a walkdown of the following underground bunkers/manholes subject to flooding:
- Manholes 16554 and 16946B. In addition, the inspectors verified problems associated with potential degradation of safety-related and/or risk-significant cables due to submergence or wetting 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 one underground cable vaults inspection sample as defined in IP 71111.06.
b. Findings
No findings were identified.
1R07 Heat Sink Performance
Annual Heat Sink Performance (71111.07A)
a. Inspection Scope
The inspectors observed the licensee's performance of Procedure 47.205.01, "RHR Division 1 Heat Exchanger Performance Test." The inspectors assessed the condition of the heat exchanger by direct observation of the performance test, review of the test results, and discussion with licensee engineering staff. The inspectors verified the acceptance criteria were satisfactorily met and verified no deficiencies existed that would adversely impact the heat exchanger's ability to transfer heat to the RHRSW system to ensure the licensee was adequately identifying and addressing problems that could affect the performance of the heat exchanger. In addition, the inspectors verified heat sink performance-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 one annual heat sink performance inspection sample as defined in IP 71111.07.
b. Findings
No findings were identified.
1R08 Inservice Inspection Activities
From September 28 through November 9, 2015, the inspectors conducted a review of the implementation of the licensee's Inservice Inspection (ISI) Program for monitoring degradation of the reactor coolant system (RCS), risk-significant piping and components, and containment systems. The inspections described in Sections 1R08.1 and 1R08.5 below constituted one ISI inspection sample as defined in IP 71111.08. Piping Systems In-Service Inspection
a. Inspection Scope
The inspectors either observed or reviewed the following non-destructive examinations mandated by the American Society of Mechanical Engineers (ASME) Code,Section XI to evaluate compliance with ASME Code,Section XI and Section V requirements; and, if any indications and defects were detected, to determine if these were dispositioned in accordance with the ASME Code or an NRC-approved alternative requirement.
- Ultrasonic examination (UT) of a risk-informed (R-A/R1.16), 4" Loop B circumferential weld, SW-RS-2-B3-W4;
- UT of a reactor pressure vessel long shell weld, 1-308B;

- VT-3 of rigid support, P44-3337-G16; and
- VT-3 of component spring, N21-3537-G04. The inspectors reviewed the following examinations completed during the previous outage with relevant/recordable conditions/indications accepted for continued service to determine whether acceptance was in accordance with the ASME Code,Section XI or an NRC-approved alternative.
- Division 2, RHR heat exchanger "B" service water elbow weld, FW-E11-3184-C, -D; and
- N21-3537-G06; feedwater piping integral attachment, lug weld SW-N21-2336-20WE. The inspectors reviewed records for the following pressure boundary weld repairs completed for risk-significant systems during the last outage to determine if the licensee applied the pre-service non-destructive examinations and acceptance criteria required by the Construction Code, and/or the NRC-approved Code relief request. Additionally, the inspectors reviewed the welding procedure specifications and supporting weld procedure qualification records to determine whether the weld procedures were qualified in accordance with the requirements of the Construction Code and the ASME Code,Section IX.
b. Findings
No findings were identified.
.2 Reactor Pressure Vessel Upper Head Penetration Inspection Activities (Not Applicable) .3 Boric Acid Corrosion Control (Not Applicable) .4 Steam Generator Tube Inspection Activities (Not Applicable) .5 Identification and Resolution of Problems
a. Inspection Scope
The inspectors performed a review of ISI-related problems entered into the licensee's corrective action program, and conducted interviews with licensee staff to determine if:
- The licensee had established an appropriate threshold for identifying ISI-related problems;
- The licensee had performed a root cause evaluation (if applicable) and taken appropriate corrective actions; and
- The licensee had evaluated operating experience and industry generic issues related to ISI and pressure boundary integrity. The inspectors performed these reviews to evaluate compliance with Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion XVI, "Corrective Action," requirements. Selected CARDs were reviewed to verify corrective actions were appropriate and implemented as scheduled. Documents reviewed are listed in the Attachment to this report.
b. Findings
No findings were identified.
1R11 Licensed Operator Requalification Program
.1 Resident Inspector Quarterly Review of Licensed Operator Requalification
a. Inspection Scope
The inspectors observed licensed operators during two annual licensed operator evaluated examination scenarios in the simulator on December 16, 2015. The inspectors assessed the operators' response to the simulated events focusing on alarm response, command and control of crew activities, communication practices, procedural adherence, and implementation of Emergency Plan requirements. The inspectors also observed the post-evaluation critique to assess the ability of the licensee's evaluators to identify performance deficiencies. The crew's performance in these areas was
compared to pre-established operator action expectations and successful critical task completion requirements. Documents reviewed are listed in the Attachment to this
report. This inspection constituted one quarterly licensed operator requalification program simulator inspection sample as defined in IP 71111.11.
b. Findings
No findings were identified.
.2 Resident Inspector Quarterly Observations During Periods of Heightened Activity or Risk
(71111.11Q)
a. Inspection Scope
On November 25, 2015, the inspectors observed licensed operators in the control room perform portions of a reactor start up at the conclusion of the F2RF17 refueling outage.
This activity required heightened awareness, additional detailed planning, and involved increased operational risk. The inspec tors evaluated the following areas:
- licensed operator performance;
- crew's clarity and formality of communications;
- ability to take timely actions in the conservative direction;
- prioritization, interpretation, and verification of annunciator alarms;
- correct use and implementation of procedures;
- control board (or equipment) manipulations;
- oversight and direction from supervisors; and
- ability to identify and implement appropriate TS actions. The performance in these areas was compared to pre-established operator action expectations, procedural compliance, and task completion requirements. In addition, the inspectors verified problems related to licensed operator performance 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 one quarterly licensed operator heightened activity/risk inspection sample as defined in IP 71111.11.
b. Findings
No findings were identified.

.4 Biennial Review
a. Inspection Scope
The following inspection activities were conducted during the week of December 7, 2015 to assess:
- (1) the effectiveness and adequacy of the licensee's implementation and maintenance of its systems approach to training (SAT) based LORT program implemented to satisfy the requirements of 10 CFR 55.59;
- (2) conformance with the requirements of 10 CFR 55.46 for use of a plant reference simulator to conduct operator licensing examinations and for satisfying experience requirements; and
- (3) conformance with the operator license conditions specified in 10 CFR 55.53. Documents reviewed are listed in the Attachment to this report.
- Problem Identification and Resolution (10 CFR 55.59(c); SAT Element 5 as Defined in 10 CFR 55.4): The inspectors evaluated the licensee's ability to assess the effectiveness of its LORT program and its ability to implement appropriate corrective actions to maintain its LORT program up-to-date. The inspectors reviewed about a dozen corrective action documents related to the plant's operation and associated responses (e.g., recent examination, inspection reports and CARDs). The inspectors reviewed the licensee's quality assurance oversight activities, including licensee training department self-assessment
reports.
- Licensee Requalification Examinations (10 CFR 55.59(c); SAT Element 4 as Defined in 10 CFR 55.4): The inspectors reviewed the licensee's program for development and administration of the LORT biennial written examination and annual operating tests to assess the licensee's ability to develop and administer examinations that were acceptable for meeting the requirements of 10 CFR 55.59(a).
- The inspectors reviewed the methodology used to construct the examination including content, level of difficulty, and general quality of the examination/ test materials. The inspectors also assessed the level of examination material duplication from week-to-week of the operating tests conducted during 2015. The inspectors reviewed the written examination given during the inspection week and associated answer keys to check for consistency and accuracy.
- The inspectors observed the administration of the annual operating test to assess the licensee's effectiveness in conducting the examinations, including the conduct of pre-examination briefings, evaluations of individual operator and crew performance, and post-examination analysis. The inspectors evaluated the performance of one crew, in parallel with the facility evaluators during three dynamic simulator scenarios, and evaluated various licensed crew members concurrently with facility evaluators during the administration of several job performance measures.
- The inspectors assessed the adequacy and effectiveness of the remedial training conducted since the last requalification examination and the training planned for the current examination cycle to ensure the licensee addressed weaknesses in licensed operator or crew performance identified during training and plant operations. The inspectors reviewed two individual remedial training plans.
- Conformance with Examination Security Requirements (10 CFR 55.49): The inspectors conducted an assessment of the licensee's processes related to examination physical security and integrity (e.g., predictability and bias) to verify compliance with 10 CFR 55.49, "Integrity of Examinations and Tests." The inspectors reviewed the licensee's examination security procedure, and observed the implementation of physical security controls (e.g., access restrictions and simulator input/output controls) and integrity measures (e.g., security agreements, sampling criteria, bank use, and test item repetition) throughout the inspection period.
- Conformance with Simulator Requirements (10 CFR 55.46): The inspectors assessed the adequacy of the licensee's simulation facility (simulator) for use in operator licensing examinations and for satisfying experience requirements.
The inspectors reviewed a sample of simulator performance test records (e.g., transient tests, malfunction tests, post-event tests, steady state tests, and core performance tests), simulator discrepancies, and the process for ensuring continued assurance of simulator fidelity in accordance with 10 CFR 55.46.
The inspectors reviewed and evaluated the discrepancy corrective action process to ensure that simulator fidelity was being maintained. Open simulator
discrepancies were reviewed for importance relative to the impact on 10 CFR 55.45 and 55.59 operator actions, as well as on nuclear and thermal hydraulic operating characteristics.
- Conformance with Operator License Conditions (10 CFR 55.53): The inspectors reviewed the licensee's program for maintaining active operator licenses to assess compliance with 10 CFR 55.53(e) and (f). The inspectors reviewed the procedural guidance and the process for tracking on-shift hours for licensed operators and which Control Room positions were granted watch-standing credit for maintaining active operator licenses.

- inspection of the drywell to assess material condition and search for loose debris, which, if present, could block floor drains or be transported to the containment suppression pool. The inspectors interviewed operations, engineering, work control, radiological protection, and maintenance department personnel and reviewed selected procedures and documents. In addition, the inspectors verified problems associated with refueling outage activities 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 one refueling outage inspection sample as defined in IP 71111.20.
b. Findings
- (1) Failure to Satisfy Technical Specification Requirements During an Unplanned Operation with the Potential to Drain the Reactor Vessel
Introduction:
A finding of very low safety significance with an associated non-cited violation of TS 3.0.4 was self-revealed on October 4, 2015, when the licensee inadvertently entered an OPDRV condition while in Mode 5 without an operable secondary containment. The licensee failed to provide adequate configuration control of reactor recirculation system boundary isolation valves while establishing conditions to support maintenance during the refueling outage.
Description:
On October 4, with Fermi 2 in Mode 5 during the refueling outage, the licensee inadvertently entered an OPDRV condition without an operable secondary containment. An OPDRV is an activity that could result in the draining or siphoning of the reactor vessel water level below the top of the fuel, without crediting the use of mitigating measures to terminate the uncovering of fuel. Secondary containment is required by TS 3.6.4.1 to be operable during an OPDRV to protect against untreated fission product release if the reactor pressure vessel water level drops and uncovers irradiated fuel since the RCS and primary containment boundaries are open during Mode 5 activities. If secondary containment is inoperable during an OPDRV, the TS requires the licensee to initiate actions to suspend the OPDRV immediately. Inasmuch as TS 3.0.4 requires the Limiting Condition for Operation of TS 3.6.4.1 to be satisfied prior to entering an OPDRV condition, entering the OPDRV without establishing secondary containment integrity was considered a condition prohibited by the plant's TS. During the refueling outage, plant operators were isolating a reactor recirculation pump seal flow switch and rotameter for replacement. Shortly after the reactor recirculation pump seal cavity drain valves were opened to depressurize and drain the seal cavity, control room operators identified a lowering SFP skimmer surge tank level and an increase in Drywell floor drain sump level, which indicated a LOI from the RCS.
Operators subsequently isolated the reactor recirculation pump seal cavity by closing the drain valves and successfully terminated t he OPDRV. The reactor recirculation pump seal drain flow was approximately 12 gallons-per-minute and lasted about 84 minutes. The event occurred with the reactor cavity filled and SFP gates removed. Reactor cavity water level and SFP water level remained constant during the event. The inspectors reviewed the licensee's apparent cause evaluation for the event and concurred with its conclusions. The direct cause was attributed to inadequate self-checking by the operators who prepared and reviewed the system tagout configuration for the maintenance because they did not include closing the reactor recirculation pump suction and discharge isolation valves, which resulted in the reactor recirculation pump and loop piping being in direct communication with the reactor vessel during draining. The apparent cause was determined to be inadequate identification of OPDRV conditions during refueling outage preparations. Those conditions that drain systems that interface with the reactor vessel were not identified and reviewed as part of the Operations Outage Challenge Meetings or the Outage Nuclear Safety Review Meetings conducted by the Outage Review Team in accordance with licensee administrative requirements to ensure OPDRV conditions did not exist, including boundary identification and positive controls. The NRC issued Enforcement Guidance Memorandum (EGM) 11-003, Revision 2, on December 13, 2013, to provide guidance on dispositioning boiling water reactor (BWR)licensee non-compliance with TS containment requirements during OPDRV operations. The NRC considered enforcement discretion related to secondary containment inoperability during Mode 5, OPDRV activities to be appropriate as long as the licensee had taken the following interim actions:
- (1) adhere to the NRC plain language meaning of OPDRV activities,
- (2) meet the requirements which specify the minimum makeup flow rate and water inventory based on OPDRV activities with long drain down times,
- (3) ensure that adequate defense-in-depth is maintained to minimize the potential for the release of fission products with secondary containment not operable by
- (a) monitoring reactor vessel water level to identify the onset of a LOI event,
- (b) maintaining the capability to isolate potential leakage paths,
- (c) prohibiting Mode 4 (cold shutdown) OPDRV activities, and
- (d) prohibiting movement of irradiated fuel with the SFP gates removed in Mode 5, and
- (4) ensure that licensees follow all other Mode 5 TS requirements for OPDRV activities. Although the violation occurred during the discretion period described in EGM 11-003, Revision 2, the NRC will not exercise enforcement discretion for this event in accordance with Section 3.5, "Violations Involving Special Circumstances," of the NRC Enforcement Policy because the licensee did not invoke the EGM and satisfy all of its criteria prior to the OPDRV, and the condition was not recognized until control room operators identified the lowering SFP skimmer surge tank level and increase in drywell floor drain sump level.
The inspectors noted, however, at the time of the event the interim mitigating actions of the EGM were met by the licensee utilizing its processes in place for refueling outage defense-in-depth measures. The licensee submitted Licensee Event Report (LER) 05000341/2015-007-00, "Operation with the Potential to Drain the Reactor Vessel with Secondary Containment Inoperable," 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 and also in accordance with 10 CFR 50.73(a)(2)(i)(B) as an operation or condition which was prohibited by the plant's TS. Refer to Section 4OA3.1 of this inspection report for the inspectors' review of the LER.
Analysis:
The inspectors determined the licensee's failure to satisfy the Limiting Condition for Operation of TS 3.6.3.1 prior to entry into an OPDRV condition was contrary to the requirements of TS 3.0.4, and was therefore, a performance deficiency warranting a significance evaluation. Consistent with the guidance in IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 7, 2012, the inspectors determined this performance deficiency was of more than minor safety significance, and thus a finding, because it was associated with the Configuration Control and Human Performance attributes of the Initiating Events Cornerstone and adversely affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the system tagout error resulted in an inadvertent and uncontrolled loss of RCS inventory. The inspectors also reviewed the examples of minor issues in IMC 0612, "Power Reactor Inspection Reports," Appendix E, "Examples of Minor Issues," dated August 11, 2009, and found no similar examples. In accordance with IMC 0609, "Significance Determination Process," Attachment 0609.04, "Initial Characterization of Findings," Table 3, "SDP [Significance Determination Process] Appendix Router," dated June 19, 2012, the inspectors determined this finding affected the Initiating Events Cornerstone, specifically the Loss of Coolant Accident-LOI Initiators contributor, and would require review using IMC 0609, Appendix G, "Shutdown Operations Significance Determination Process," dated May 9, 2014, since the reactor was in Mode 5. The inspectors performed a Phase 1 SDP review of this finding using the guidance provided in IMC 0609, Appendix G, Exhibit 2, "Initiating Events Screening Questions," and determined this finding would require a detailed risk evaluation. For LOI initiating events, Question B.3 of Exhibit 2 asked: "Is the LOI event self-limiting such that leakage will stop before impacting the operating method of decay heat removal." The inspectors answered "NO" to this question since RCS leakage through the reactor recirculation pump seals would have impacted decay heat removal if no action had been taken to isolate or mitigate the LOI. Therefore, a detailed risk evaluation was required. The Region III Senior Risk Analyst (SRA) conducted an assessment of the risk significance of the finding in accordance with IMC 0609, Appendix G, Attachment 3, "Phase 2 Significance Determination Process Template for BWR During Shutdown,"
February 28, 2015. The finding was considered to be a precursor to an initiating event for LOI. The plant operating state (POS) was determined to be "POS 3," since the reactor vessel water level was equal to or greater than the minimum TS required level for movement of irradiated fuel assemblies within the reactor vessel. The initiating event likelihood for LOI using Table 2, "Initiating Event Likelihoods (IELs) for LOI Precursors,"
was determined to be "4" because the RHR system remained operating for decay heat removal during this event, reactor cavity level indication remained available, and operators readily identified the leakage path and isolated it. With the RCS leakage that was present and the amount of water present in the reactor cavity, it would have taken greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to drain the reactor cavity to the reactor vessel flange. Using Worksheet 3, "SDP Worksheet for a BWR Plant-Loss of Inventory in POS 3 (Cavity Flooded)," the SRA evaluated the equipment mitigation capability and operator recovery credit. The combined sequences from Worksheet 3 resulted in a delta core damage frequency of less than or equal to 1E-7/year. The assessment was continued using IMC 0609, Appendix H, "Containment Integrity Significance Determination Process," dated May 6, 2004. The SRA used Section 5.2 of Appendix H, "Approach for Assessing Type 'A' Findings During Shutdown," to evaluate the delta large early release frequency for this event. Since the plant was in "POS 3" during the OPDRV time window and the event occurred greater than eight days since the plant was shut down, the finding screened as having very low safety significance for delta large early release frequency per Step 2 of Section 5.2 of Appendix H. Based on the results of the detailed risk evaluation, the inspectors determined the finding was of very low safety significance (Green). The inspectors concluded this finding affected the cross-cutting area of human performance and the cross-cutting aspect of avoiding complacency. The cause of the event was primarily attributed to a failure to properly use human error reduction techniques, specifically inadequate self-checking by the operators who prepared and reviewed the system tagout configuration for the maintenance, as well as inadequate identification of OPDRV conditions during refueling outage preparations. [H.12]
Enforcement:
Technical Specifications 3.6.4.1 states, in part, the secondary containment shall be operable during operations with the potential to drain the reactor vessel. With the above requirement not satisfied, immediately initiating action is required to suspend operations with the potential to drain the reactor vessel. Technical Specificaitons 3.0.4.a states, in part, when a Limiting Condition for Operation is not met, entry into an operational mode or other specified condition in the applicability shall only be made when the associated actions to be entered permit continued operation in the operational mode or other specified condition in the applicability for an unlimited period of time. Contrary to the above, at about 9:56 a.m., on October 4, the licensee entered an OPDRV condition without satisfying the Limiting Condition for Operation of TS 3.6.4.1.
This is a violation of TS 3.0.4. Because this violation was not repetitive or willful, was of very low safety significance, and was entered into the licensee's corrective action program, it is being treated as a Non-Cited Violation consistent with Section 2.3.2.a of the NRC Enforcement Policy (NCV 05000341/2015004-01, Failure to Satisfy Technical Specification Requirements during an Unplanned Operation with the Potential to Drain the Reactor Vessel). The licensee entered this violation into its corrective action program as CARD 15-27270. As an immediate corrective action, the licensee terminated the OPDRV and restored compliance with the TS by closing the recirculation pump seal cavity drain valves to isolate the drain path. In addition, the licensee reviewed all remaining refueling outage system tagouts that interfaced with the reactor vessel to ensure appropriate configuration controls were established to prevent impacting reactor vessel water level, initiated actions to make procedure changes to improve its processes for review of system tagouts for conditions that drain system s that interface with the reactor vessel, and communicated lessons learned from this event with plant operators.

.1 Maintenance of Emergency Preparedness
a. Inspection Scope
The inspectors reviewed the Nuclear Quality Assurance staff's 2015 audit of the Fermi-2 power plant's emergency preparedness program to determine that the independent assessments met the requirements of 10 CFR 50.54(t). The inspectors reviewed samples of corrective action program records associated with the 2014 biennial exercise, as well as various RERP drills conducted in 2014 and 2015, in order to determine whether the licensee fulfilled drill commitments and to evaluate the licensee's efforts to identify and resolve identified issues. The inspectors reviewed a sample of RERP items and corrective actions related to the plant's RERP Program, and activities to determine whether corrective actions were completed in accordance with the licensee's corrective action program. Documents reviewed are listed in the Attachment to this report. This maintenance of emergency preparedness inspection constituted one inspection sample as defined in IP 71114.05.

RADIATION SAFETY
2RS1 Radiological Hazard Assessment and Exposure Controls
This inspection constituted one complete inspection sample as defined in IP 71124.01.
.1 Inspection Planning (02.01)
a. Inspection Scope
The inspectors reviewed all licensee performance indicators for the Occupational Exposure Cornerstone for follow-up. The inspectors reviewed the results of the radiation protection program audits (e.g., licensee's quality assurance audits or other independent audits). The inspectors reviewed any reports of operational occurrences related to occupational radiation safety since the last inspection. The inspectors reviewed the results of the audit and operational report reviews to gain insights into overall licensee performance.
b. Findings
No findings were identified.
.2 Radiological Hazard Assessment (02.02)
a. Inspection Scope
The inspectors determined if there have been changes to plant operations since the last inspection that may result in a significant new radiological hazard for onsite workers or members of the public. The inspectors evaluated whether the licensee assessed the potential impact of these changes and has implemented periodic monitoring, as appropriate, to detect and quantify the radiological hazard. The inspectors reviewed the last two radiological surveys from selected plant areas and evaluated whether the thoroughness and frequency of the surveys were appropriate for the given radiological hazard. The inspectors conducted walkdowns of the facility, including radioactive waste processing, storage, and handling areas to evaluate material conditions and performed independent radiation measurements to verify conditions. The inspectors selected the following radiologically risk-significant work activities that involved exposure to radiation:
- Radiation Work Permit (RWP) 153015; CRDM exchange/support tasks-drywell, reactor building bullpen; Revision 2;
- RWP 153011; disassemble, inspect, replace valve disc soft seat on B2100F076A (B) and repair B2100F010 A (B); Revision 1; and
- RWP 153016; MSIVs-inspect, transfer and rework in the drywell and reactor building steam tunnel; Revision 4. For these work activities, the inspectors assessed whether the pre-work surveys performed were appropriate to identify and quantify the radiological hazard and to establish adequate protective measures. The inspectors evaluated the Radiological Survey Program to determine if hazards were properly identified, including the following:
- identification of hot particles;
- the presence of alpha emitters;
- the potential for airborne radioactive materials, including the potential presence of transuranics and/or other hard-to-detect radioactive materials (This evaluation may include licensee planned entry into non-routinely entered areas subject to previous contamination from failed fuel.);
- the hazards associated with work activities that could suddenly and severely increase radiological conditions and that the licensee has established a means to inform workers of changes that could significantly impact their occupational
dose; and
- severe radiation field dose gradients that can result in non-uniform exposures of the body. The inspectors observed work in potential airborne areas and evaluated whether the air samples were representative of the breathing air zone. The inspectors evaluated whether continuous air monitors were located in areas with low background to minimize false alarms and were representative of actual work areas. The inspectors evaluated the licensee's program for monitoring levels of loose surface contamination in areas of the plant with the potential for the contamination to become airborne.
b. Findings
No findings were identified.
.3 Instructions to Workers (02.03)
a. Inspection Scope
The inspectors selected various containers holding non-exempt licensed radioactive materials that may cause unplanned or inadvertent exposure of workers, and assessed whether the containers were labeled and controlled in accordance with 10 CFR 20.1904, "Labeling Containers," or met the requirements of 10 CFR 20.1905(g), "Exemptions To Labeling Requirements." The inspectors reviewed the following RWPs used to access high-radiation areas and evaluated the specified work control instructions or control barriers:
- RWP 153011; disassemble, inspect, replace valve disc soft seat on B2100F076A (B) and Repair B2100F010 A (B); Revision 1; and
- RWP 153016; MSIVs-inspect, transfer and rework in the drywell and reactor building steam runnel; Revision 4. For these RWPs, the inspectors assessed whether allowable stay times or permissible dose (including from the intake of radioactive material) for radiologically significant work under each RWP were clearly identified.
The inspectors evaluated whether electronic personal dosimeter alarm set-points were in conformance with survey indications and plant policy. The inspectors reviewed selected occurrences where a worker's electronic personal dosimeter noticeably malfunctioned or alarmed. The inspectors evaluated whether workers responded appropriately to the off-normal condition. The inspectors assessed whether the issue was included in the corrective action program and dose evaluations were conducted as appropriate. For work activities that could suddenly and severely increase radiological conditions, the inspectors assessed the licensee's means to inform workers of changes that could significantly impact their occupational dose.
b. Findings
No findings were identified.
.4 Contamination and Radioactive Material Control (02.04)
a. Inspection Scope
The inspectors observed locations where the licensee monitors potentially contaminated material leaving the radiological control area and inspected the methods used for control, survey, and release from these areas. The inspectors observed the performance of personnel surveying and releasing material for unrestricted use and evaluated whether the work was performed in accordance with plant procedures and whether the procedures were sufficient to control the spread of contamination and prevent unintended release of radioactive materials from the site. The inspectors assessed whether the radiation monitoring instrumentation had appropriate sensitivity for the type(s) of radiation present. The inspectors reviewed the licensee's criteria for the survey and release of potentially contaminated material. The inspectors evaluated whether there was guidance on how to respond to an alarm that indicates the presence of licensed radioactive material. The inspectors reviewed the licensee's procedures and records to verify the radiation detection instrumentation was used at its typical sensitivity level based on appropriate counting parameters. The inspectors assessed whether or not the licensee has established a de facto "release limit" by altering the instrument's typical sensitivity through such methods as raising the energy discriminator level or locating the instrument in a high-radiation background area. The inspectors selected several sealed sources from the licensee's inventory records and assessed whether the sources were accounted for and verified to be intact. The inspectors evaluated whether any transactions, since the last inspection, involving nationally tracked sources were reported in accordance with 10 CFR 20.2207.
b. Findings
No findings were identified.
.5 Radiological Hazards Control and Work Coverage (02.05)
a. Inspection Scope
The inspectors evaluated ambient radiological conditions (e.g., radiation levels or potential radiation levels) during tours of the facility. The inspectors assessed whether the conditions were consistent with applicable posted surveys, RWPs, and worker briefings. The inspectors evaluated the adequacy of radiological controls, such as required surveys, radiation protection job coverage (including audio and visual surveillance for remote job coverage), and contamination controls. The inspectors evaluated the licensee's use of electronic personal dosimeters in high-noise areas as high-radiation
area monitoring devices. The inspectors assessed whether radiation monitoring devices were placed on the individual's body consistent with licensee procedures. The inspectors assessed whether the dosimeter was placed in the location of highest expected dose or that the licensee properly employed an NRC-approved method of determining effective dose equivalent. The inspectors reviewed the application of dosimetry to effectively monitor exposure to personnel in high-radiation work areas with significant dose rate gradients. The inspectors reviewed the following RWPs for work within airborne radioactivity areas with the potential for individual worker internal exposures:
- RWP 153011; disassemble, inspect, replace valve disc soft seat on B2100F076A (B) and repair B2100F010 A (B); Revision 1; and
- RWP 153016; MSIVs-inspect, transfer and rework in the drywell and reactor building steam tunnel; Revision 4. For these RWPs, the inspectors evaluated airborne radioactive controls and monitoring, including potential for significant airborne levels (e.g., grinding, grit blasting, system breaches, entry into tanks, cubicles, and reactor cavities). The inspectors assessed barrier (e.g., tent or glove box) integrity and temporary high-efficiency particulate air ventilation system operation. The inspectors examined the licensee's physical and programmatic controls for highly activated or contaminated materials (i.e., nonfuel) stored within spent fuel and other storage pools. The inspectors assessed whether appropriate controls (i.e., administrative and physical controls) were in place to preclude inadvertent removal of these materials from the pool. The inspectors examined the posting and physical controls for selected high-radiation areas and very-high radiation areas to verify conformance with the occupational performance indicator.
b. Findings
No findings were identified.
.6 Risk-Significant High-Radiation Area and Very-High Radiation Area Controls (02.06)
a. Inspection Scope
The inspectors discussed with the radiation protection manager the controls and procedures for high-risk, high-radiation areas and very-high radiation areas. The inspectors discussed methods employed by the licensee to provide stricter control of very-high radiation area access as specified in 10 CFR 20.1602, "Control of Access to Very-High Radiation Areas," and Regulatory Guide 8.38, "Control of Access to High and Very-High Radiation Areas of Nuclear Plants." The inspectors assessed whether any changes to licensee procedures substantially reduce the effectiveness and level of worker protection. The inspectors discussed the controls in place for special areas that have the potential to become very-high radiation areas during certain plant operations with first-line health physics supervisors (or equivalent positions having backshift health physics oversight authority). The inspectors assessed whether these plant operations require communication beforehand with the health physics group, so as to allow corresponding timely actions to properly post, control, and monitor the radiation hazards including re-access authorization. The inspectors evaluated licensee controls for very-high radiation areas and areas with the potential to become very-high radiation areas to ensure that an individual was not able to gain unauthorized access to the very-high radiation areas.
b. Findings
No findings were identified.
.7 Radiation Worker Performance (02.07)
a. Inspection Scope
The inspectors observed radiation worker performance with respect to stated radiation protection work requirements. The inspectors assessed whether workers were aware of the radiological conditions in their workplace and the RWP controls/limits in place, and whether their performance reflected the level of radiological hazards present. The inspectors reviewed radiological problem reports since the last inspection that found the cause of the event to be human performance errors. The inspectors evaluated whether there was an observable pattern traceable to a similar cause. The inspectors assessed whether this perspective matched the corrective action approach taken by the licensee to resolve the reported problems. The inspectors discussed with the radiation protection manager any problems with the corrective actions planned or taken.
b. Findings
No findings were identified.
.8 Radiation Protection Technician Proficiency (02.08)
a. Inspection Scope
The inspectors observed the performance of the radiation protection technicians with respect to all radiation protection work r equirements. The inspectors evaluated whether technicians were aware of the radiological conditions in their workplace and the RWP controls/limits, and whether their performance was consistent with their training and qualifications with respect to the radiological hazards and work activities. The inspectors reviewed the radiological problem reports since the last inspection that found the cause of the event to be radiation protection technician error. The inspectors evaluated whether there was an observable pattern traceable to a similar cause. The inspectors assessed whether this perspective matched the corrective action approach taken by the licensee to resolve the reported problems.
b. Findings
No findings were identified.
.9 Problem Identification and Resolution (02.09)
a. Inspection Scope
The inspectors evaluated whether problems associated with radiation monitoring and exposure control 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 that involve radiation monitoring and exposure controls. The inspectors assessed the licensee's process for applying operating experience to its plant.
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 Daily Corrective Action Program Reviews
a. Inspection Scope
In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's CAP. This review was accomplished through inspection of the station's daily CR packages. These daily reviews were performed by procedure as part of the inspectors' daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.
b. Findings
No findings were identified.
4OA3 Follow-Up of Events and Notices of Enforcement Discretion
.1 (Closed) LER 05000341/2015-007-00, "Operation with the Potential to Drain the Reactor Vessel with Secondary Containment Inoperable" On October 4, 2015, the licensee inadvertently entered an OPDRV condition while in Mode 5 (refueling) without an operable secondary containment.
The cause of the event was inadequate configuration control of reactor recirculation system boundary isolation valves while establishing conditions to support maintenance during the F2RF17 refueling
outage. The licensee completed an 8-hour notification call (Event Notification 51449) on October 4, 2015 to report the inadvertent OPDRV with an 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 05000341/2015-007-00 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 were needed to control the release of radioactive material and also in accordance with 10 CFR 50.73(a)(2)(i)(B) as an operation or condition which was prohibited by the plant's TS. The inspectors reviewed this issue and documented a NCV of TS 3.0.4 for the licensee's failure to satisfy the Limiting Condition for Operation of TS 3.6.3.1 prior to entry into an OPDRV condition. The performance issue related to this event, the safety significance, the cause, and the corrective actions are discussed in more detail in Section 1R20.1 of this inspection report. The inspectors determined the information provided in LER 05000341/2015-007-00 did not raise any new issues or change the conclusion of the initial review. This inspection constituted one event follow-up inspection sample as defined in IP 71153.
LER 05000341/2015-007-00 is closed.
4OA5 Other Activities
.1 (Closed) Unresolved Item 05000341/2014005-03, "Spent Fuel Pool Securement of Irradiated Local Power Range Monitors" In November 2014, during inspection activities associated with the storage and securement of irradiated materials within the SFP, the inspectors identified an Unresolved Item (URI) associated with the securement of irradiated local power range
monitors (LPRM) within the SFP. Specifically, the inspectors observed a series of locked metal sleeves attached to a handrail surrounding the SFP. These locked metal sleeves extend into the SFP. From each of these sleeves were suspended two or three irradiated LPRM. These metal sleeves had the potential to rotate at the point of securement to the handrail. This rotation would increase the possibility of an individual obtaining access to the irradiated LPRM. The inspectors discussed this concern, along with the potential radiation exposure rates on the irradiated LPRM, with the licensee.
Specifically, the NRC provides guidance on this subject in Regulatory Guide 8.38, "Controls of Access to High and Very-High Radiation Areas in Nuclear Power Plants," Revision 1. Section 4.2, "Spent Fuel Pools, Reactor Vessels, and Refueling Cavities,"
provides the following in part, "Therefore, these pool areas do not have to be controlled as high or very-high radiation areas solely because of the materials in them, provided that the following criteria are fulfilled: Control measures are implemented to ensure that activated materials are not raised above or brought near the surface of the pool water."
The inspectors could not evaluate whether the controls as originally implemented were adequate to prevent activated materials from being raised above or brought near the
surface of the pool water. Consequently, the inspectors opened an URI in NRC Inspection Report 05000341/2014005.
Subsequently, the licensee provided the physical characteristics of the items hanging below the water surface and attached to the handrails. Specifically, the licensee indicated the long arms locked to the handrails act as a lever and would require about 350 pounds of force to move. Although recent radiation surveys were not available
due to the close proximity to irradiated fuel, irradiated LPRM are commonly greater than 500 R/hour if raised above the water surface. Additionally the inspectors reviewed documents developed by the NRC. The inspectors determined that Question 448 from the "Frequently Asked Questions about Health Physics Based on 10 CFR Part 20," could be applied to the issue identified during the inspection. "Question 448: If irradiated hardware, suspended (e.g., on a lanyard) in the SFP, is potentially reading greater than 500 rads/hour at one meter (i.e., if it were removed from the pool), does access to this hardware require posting and control as a very-high radiation area? Answer: No. See Section 4.2, "Materials," in Regulatory Guide 8.38, "Control of Access to High and Very-High Radiation Areas in Nuclear Power Plants." Also see Health Physics Position document HPPOS-245 (NUREG/CR-5569). Although this position document was written to address access controls for SFPs under the unrevised 10 CFR Part 20 requirements for high-radiation areas, it also applies to these access controls under the revised 10 CFR Part 20 requirements for both high and very-high radiation areas. The essential point is that although movement of radioactive material stored in the pool has the potential to create a high, or very-high, radiation area around the pool, those areas are not created until movement of the material actually results in a radiation level, in an area that is accessible to individuals, that meets the dose criterion in the definitions of a high, or a very-high, radiation area. Information Notice No. 90-33, dated May 9, 1990, is also relevant. After providing reviews of a number of events in which sources of unexpected occupational radiation exposures were encountered in activities associated with SFPs, this notice provides suggestions (which are not regulatory requirements) for radiological control considerations that can help minimize the possibility of unexpected exposures from radiation sources in these pools. (References: 10 CFR 20.1602, 10 CFR 20.1601, 10 CFR 20.1003)." The inspectors determined that items in the SFP that have the potential to create very-high radiation areas do not require controls to ensure that an individual is not able to gain unauthorized or inadvertent access to the items. However, it is important to be aware that a very-high radiation area could result from inadvertent surfacing of the item(s) and if a very-high radiation area were to result, the proper posting and controls would be required at that time. URI 05000341/2014005-03 is closed.
.2 (Closed) URI 05000341/2015003-01, "Inadequate Simulator Fidelity Regarding the Ability to Model Thermal-Hydraulic Instabilities" On March 19, 2015, with Fermi-2 at full power, control room operators stopped reactor recirculation pump 'A' after it had lost both normal and emergency cooling water supply.
With one loop of reactor recirculation in operation, reactor power initially lowered to about 62 percent. Power then slowly rose to about 74 percent due to loss of feedwater heating. With the reactor operating in the Exit Region of the Power-to-Flow Map, control room operators implemented Abnormal Operating Procedure 20.138.01, "Recirculation Pump Trip," and identified thermal-hydraulic instabilities by receiving "OPRM [Oscillating Power Range Monitor] Upscale" alarms. The operators reviewed the procedure and briefed subsequent actions of the procedure to insert control rods when the reactor scrammed on OPRM upscale logic. From the time operators tripped the 'A' reactor recirculation pump until the OPRM logic tripped the reactor, 10 minutes had elapsed and several upscale alarms had been received. Previously, in May 2000, the licensee enabled the OPRM trip features in response to NRC Bulletin 88-07 and Generic Letter 94-02, which addressed long-term solutions to address thermal-hydraulic instabilities during operation with high reactor power and low recirculation flow. With a sense that the core was protected from thermal-hydraulic instabilities by the OPRMs, operator actions to exit or scram out of the region of instability was lessened. Hence, the abnormal operating procedures reflected this fundamentals by the licensee removing these actions from the immediate action section of the procedures and including them in the subsequent actions section. The licensed operator training staff reviewed the OPRM upscale trip from March 2015 and subsequent operator actions in CARD 15-22090. The root-cause evaluation cited an operator delay to take actions to leave the Exit Region of the Power-to-Flow Map due to less than adequate procedures and training resulting from an over reliance on the OPRM function to protect the core from thermal-hydraulic instabilities. Additionally, licensed operator training was not effective in providing operators proficiency to maneuver the reactor when in the region of instability. The inspectors previously reviewed this event and documented a finding with an associated NCV of 10 CFR 50, Appendix B, Criterion V, "Instructions, Pr ocedures and Drawings," in NRC Inspection Report 05000341/2015003 for the licensee's failure to maintain response procedures appropriate to the circumstances to direct licensed reactor operators to take timely mitigating actions when the reactor was operating in a condition more susceptible to core thermal-hydraulic instability. Licensed operators received training on the system including classroom sessions and simulator scenario operations and demonstrated proficiency during a 2014 licensed operator requalification training cycle. Four of five crews demonstrated control rod insertion within 5 minutes of a reactor recirculation pump trip during this training. The training scenario consisted of manual insertion of two malfunctions, a reactor recirculation pump trip and average power range monitor oscillations. Since the simulator was not capable of emulating the neutron oscillation condition that occurred during the event, licensed operator trainers typically inputted a malfunction that mimicked thermal-hydraulic instabilities. However, the OPRM upscale alarms seen in the simulator were less frequent than the OPRM upscale alarms seen in the plant during the event in March 2015. Although malfunctions inserted by the trainers during simulator scenarios mimicked core instabilities, these instabilities were similar to, but not in the expected range of the instabilities observed by the operating crew on March 19, 2015.
The inspectors noted that thermal-hydraulic instabilities are difficult to predict and characterize due to their unstable nature. The licensee noted this training weakness and other training weaknesses in the Performance Improvement and Learning Action Request for CARD 15-22090. The inspectors determined the simulator fidelity concern was not a violation of 10 CFR 55 regulations, nor was this a performance deficiency since the licensee had a self-imposed standard to train its licensed operators on operations with thermal-hydraulic instabilities and licensed operators demonstrated this during requalification. Similarly, American National Standard Institute 3.5-1985, "Nuclear Power Plant Simulators for Use in Operator Training," did not require testing the simulator for thermal-hydraulic instabilities. Corrective actions to improve the thermal-hydraulic instabilities algorithm were still ongoing and not complete during the inspection in December 2015.

4OA6 Management Meetings
.1 Resident Inspectors' Exit Meeting The inspectors presented the inspection results to Mr. K. Polson and other members of the licensee's staff on January 12, 2016.
The licensee acknowledged the findings presented. Proprietary information was examined during this inspection, but is not specifically discussed in this report.
.2 Interim Exit Meetings Interim exit meetings were conducted for:
- The inspection results for the ISI Activities inspection with Mr. V. Kaminskas on November 30, 2015;
- The inspection results for the Radiological Hazard Assessment and Exposure Controls inspection with Mr. R. LaBurn via teleconference on December 15, 2015;
- The inspection results for the Emergency Preparedness Program inspection with Mr. M. Philippon on December 3, 2015;
- The inspection results for the Biennial Licensed Operator Requalification Program area assessment with Mr. M. Philippon on December 11, 2015; and
- The 2015 licensed operator annual operator test results with Mr. M. Donigian via e-mail on January 4, 2016. The inspectors confirmed none of the potential report input discussed was considered proprietary.
4OA7 Licensee-Identified Violations The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as a NCV.
- Technical Specification 5.7.1, states in part, that each high-radiation area, as defined in 10 CFR 20, in which the intensity of radiation is greater than 100 millirem/hour but less than 1000 millirem/hour, shall be barricaded and conspicuously posted as a high-radiation area. Contrary to the above, on September 23, 2015, the licensee discovered that high-radiation area conditions existed outside a barricaded and posted high-radiation area in the reactor building steam tunnel. Specifically, a worker performing testing activities questioned the placement of the high-radiation boundary in the reactor building steam tunnel. The radiation protection department performed confirmatory surveys which indicated a high-radiation area existing outside the established high-radiation area boundary near a reactor water clean-up line. The licensee then expanded the existing high-radiation area barricades and postings to include this area. The licensee documented this issue in CARD 15-26864. The finding was determined to be of very low safety significance (Green) because it was not an as-low-as-reasonably-achievable planning issue, there was no overexposure nor potential for overexposure, and the licensee's ability to assess dose was not compromised.
