EXECUTIVE
SUMMARY
Using the methodology of (Nuclear Energy Institute) NEI 12-01, Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communications Capabilities, this report presents the results of an assessment of the capability of the Browns Ferry Nuclear (BFN) Plant on-shift staff and augmented Emergency Response Organization (ERO) to respond to a beyond design basis external event (BDBEE). The assumptions for the NEI 12-01 Phase 2 scenario postulate that the BDBEE involves a large-scale external event that results in:
A An extended loss of all AC power (ELAP)
B. An extended loss of ultimate heat sink (UHS)
C. Impact on all units (all units are in operation at the time of the event)
D. Impeded access to the units by off-site responders as follows:
O to 6 Hours Post Event - No site access. This duration reflects the time necessary to clear roadway obstructions, use different travel routes, mobilize alternate transportation capabilities (e.g., private resource providers or public sector support), etc.
6 to 24 Hours Post Event - Limited site access. Individuals may access the site by walking, personal vehicle or via alternate transportation capabilities (e.g.,
private resource providers or public sector support).
24+ Hours Post Event - Improved site access. Site access is restored to a near-normal status and/or augmented transportation resources are available to deliver equipment, supplies and large numbers of personnel.
A team of subject matter experts from Operations, Maintenance, Radiation Protection, Chemistry, Security, Emergency Preparedness and industry consultants performed a tabletop evaluation in December 2014 for the on-shift portion of the assessment. The participants reviewed the assumptions and existing procedural guidance, including applicable draft FLEX Support Instructions (FSls) for coping with a BDBEE using minimum on-shift staffing. Particular attention was given to the sequence and timing of each procedural step, its duration, and the on-shift individual performing the step to account for both the task and time motion analyses of NEI 10-05, Assessment of On-Shift Emergency Response Organization Staffing and Capabilities.
Analysis result items are listed in Section 3.4 and have been entered into the corrective action program.
1.1 On-shift ERO Analysis The on-shift ERO analysis concluded that the current BFN on-shift staffing present for the "no site access" 6-hour time period is sufficient to perform the EOI, FSI and emergency response tasks. However, shift personnel are not yet trained to perform the FSI tasks.
1.2 Expanded ERO Analysis The expanded ERO analysis concluded that the current BFN augmented ERO is sufficient to fill positions for the expanded ERO functions. Thus, the ERO resources and capabilities necessary to implement Transition Phase coping strategies performed after the end of the "no site access" 6-hour time period exist in the current program.

INTRODUCTION In March 2012, the Nuclear Regulatory Commission (NRC) issued a §50.54(f) request for information regarding recommendations from the near-term task force review of insights from the Fukushima Dai-lchi accident. Information requests related to Emergency Preparedness were contained in Enclosure 5 of the §50.54(f) letter 1. contained two requested actions; one involving performance of a staffing assessment and the other a communications assessment. The actions for the staffing assessment are summarized as follows:
It is requested that addressees assess their current staffing levels and determine the appropriate staff to fill all necessary positions for responding to a multi-unit event during a beyond design basis natural event and determine if any enhancements are appropriate given the considerations of Near-Term Task Force (NTTF)
Recommendation 9. 32.
A two-phased approach was established by the industry to respond to the information requests contained in the §50.54(f) letter associated with staffing.
Additionally, NEI developed a technical report (NEI 12-01, Guideline for Assessing Beyond Design Basis Accident Response Staffing and Communications Capabilities) that includes the recommended criteria for use in performing the staffing assessment for a beyond design basis external event. The criteria presented in the NEI 12-01 technical report provide for documenting the organizational capabilities that will facilitate simultaneous performance of accident mitigation and repair actions following a beyond design basis external event.
Note - Use of the term ELAP throughout this report also assumes a loss of the ultimate heat sink as part of the event.
Phase 1 Staffing Assessment The objective of the Phase 1 staffing assessment was to evaluate the on-site and augmented staff needed to respond to a large-scale external event at a multi-unit site meeting the conditions described in the NEI 12-01 assumptions, NOT including staffing needed to implement actions that address NRC Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events (EA-12-049). That is, the Phase 1 staffing assessment considered the requested functions except those related to Order EA-12-049.
The BFN Phase 1 staffing assessment was performed and submitted to the NRC on 4/30/14.
1 NRC Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights from the Fukushima Daiichi Accident, dated March 12, 2012 [ADAMS ML12053A340]

BFN NEI 12-01Phase2 ELAP ERO Staffing Analysis Report Phase 2 Staffing Assessment Sites with one or more operating units are required to perform a Phase 2 staffing assessment no later than 4 months prior to beginning of the second refueling outage (as used within the context of NRC Order EA-12-049) or December 31, 2016, whichever comes first. In contrast to the Phase 1 staffing assessment, the Phase 2 staffing assessment considers the requested functions related to Order EA-12-049.
The Phase 2 staffing assessment for response functions related to Order EA-12-049 must be based on the actions delineated in the procedures and guidelines developed in response to the Order to ensure accurate results. Once the site-specific actions associated with the new response strategies are defined (i.e., down to the procedure or guideline step level), the staffing needed to perform these actions can be assessed with the necessary level of accuracy.
The results of the Phase 2 assessment have been verified and validated to ensure adequacy and accuracy. In accordance with the requirements of 10 CFR 50, Appendix B, corrective actions and enhancements identified during the assessment are entered into the corrective action program. With regard to this assessment, analysis result items related to ERO staffing that constitute an unsatisfactory result in accordance with the specifications of NEI 10-05 or NEI 12-01 are entered into the corrective action program.
Draft Emergency Operating Instruction (EOI) and FSI documents were used to conduct the staffing assessments. Prior to the BFN implementation date associated with Order EA-12-049 per the current refueling outage schedule, a review of this report will be performed based on the final validated FSls and any applicable new procedures not available when the staffing table tops were performed. This action item has been entered into the corrective action program. This report will be updated if the staffing assessment results change.

PHASE 2 STAFFING ANALYSIS
SUMMARY
The on-shift ERO analysis concluded that the current BFN on-shift staffing present for the "no site access" 6-hour time period is sufficient to perform the EOI, FSI and emergency response tasks. However, shift personnel are not yet trained to perform the FSI tasks.
The expanded ERO analysis concluded that the current BFN augmented ERO is sufficient to fill positions for the expanded ERO functions. Thus, the ERO resources and capabilities necessary to implement Transition Phase coping strategies performed after the end of the "no site access" 6-hour time period exist in the current program.
3.1 On-Shift Staffing Task Analysis Results Refer to Section 6.2, On-Shift Staffing Analysis Results Tables, for documentation of the on-shift staffing task analysis results.
3.1.1 Unassigned Tasks The task analysis did not identify any unassigned tasks.
3.1.2 Potential Overlap The task analysis identified one (1) potential task overlap that was performed by on-shift personnel in response to the ELAP event.
- 1) The Shift Manager performed the task of State notification (5/9). Per Table 3.1 of NEI 10-05, Shift Managers that perform the task of State notification are required to have the collective performance of all assigned tasks analyzed and validated by a time motion study.
The Nuclear Security Shift Supervisor (NSSS) and/or other on-shift security personnel perform security contingency plan and EP response tasks (personnel accountability) during an ELAP event. A representative of the BFN Security Department analyzed the EP task assigned to on-shift security individuals. It was concluded that performance of the EP task did not cause an overlap with their tasks related to the Security Plan. Tasks related to the Security Plan are not specifically documented in this analysis due to their security-sensitive nature. No security personnel credited in the Security Plan were assigned tasks associated with the implementation of mitigating strategies during the ELAP event.
3.1.3 Performance Validation Note - Per NEI 10-05, a validated task is one that has a controlling method (i.e., a program or process) by which the capability to perform the task has been analyzed, such as within the Operations Training Program or the EP Drill Program.
The task analysis did not identify any un-validated EOI or EPIP tasks performed by the on-shift positions.
The task analysis did identify that the performance of FSI tasks are currently not incorporated into the appropriate training program.

BFN NEI 12-01 Phase 2 ELAP ERO Staffing Analysis Report 3.2 On-Shift Staffing Time Motion Study (TMS) Results Note - Time motion analysis data was developed during the task analysis using draft FSls and the informed judgment of the FLEX subject matter experts. In accordance with the methodology provided in NEI 10-05, informed judgment can be used for tasks where directly applicable operating experience is not available and actual timed performance is not practical.
Refer to Section 6.3, ELAP On-Shift Staffing Task Timetable, for the on-shift staffing task timing and sequence analysis results.
3.2.1 Unassigned Tasks The time motion analysis did not identify any unassigned tasks.
3.2.2 Potential Overlaps Identified as Concurrent Tasks that are not an Overburden The Shift Manager performed the task of State notification (5/9) while simultaneously performing operations I emergency response oversight tasks and directing initial FLEX alignment actions. The specific activity involved the initial notifications to the State for both the SAE and GE classifications that last 2 minutes for each notification. Follow-up notifications were subsequently turned over to the CECC.
Per NEI 10-05 Section 4, for certain responsibilities it is possible for an ERO position to perform some overlapping tasks without experiencing overload, which is frequently the case for personnel performing those tasks within an operating center.
In these cases, BFN has concluded through formal evaluation that the task of performing State notifications (5/9) does not significantly interfere with performing operations I emergency response oversight tasks and directing initial FLEX alignment actions. The notification task is considered to be equivalent to other tasks categorized as simple and brief communications, and thus does not result in task overload for the Shift Manager.
3.3 Augmented and Expanded ERO Staffing Assessment Results Refer to Section 7 for details of the expanded ERO functional staffing resources.
The expanded ERO analysis did not identify a shortage of qualified augmented ERO personnel to fill the expanded ERO positions assigned to perform the ELAP functions.
3.4 List of Analysis Results The following analysis result items that potentially hinder station personnel from performing response tasks in a timely manner have been entered into the corrective action program to document the actions associated with this assessment report:
Analysis Result Items Description
- 1: FSI task training/qualification has not yet been developed and incorporated in the applicable departmental training programs.
Page 7
BFN NEI 12-01 Phase 2 ELAP ERO Staffing Analysis Report 4
SCOPE OF THE ELAP ERO STAFFING ASSESSMENT
- 1. Evaluate the ability of the on-shift staff to implement Initial Phase coping actions and, consistent with the site access assumption, evaluate Transition Phase actions that must be performed prior to the end of the "no site access" time period.
Initial Phase - Implementation of strategies that generally rely upon installed plant equipment.
Transition Phase - Implementation of strategies that involve the use of on-site portable equipment and consumables to extend the coping period, and prevent a loss of functions needed for core cooling, containment, and spent fuel pool cooling. Setup for these strategies may be performed prior to the end of the Initial Phase as determined by procedure.
- 2. Evaluate the applicable EOI actions and FSI strategies in place at the time of the assessment for the ELAP event.
Such actions include the shedding of non-essential battery loads, use of portable generators or batteries, opening room and cabinet doors, water/coolant conservation or makeup using portable equipment, etc.
These actions do not include those associated with cross-tying AC power sources or electrical distribution busses between units for multi-unit sites (since all units are assumed affected).
- 3. Evaluate the draft EOls and FSls for responding to an extended loss of AC power affecting both units.
- 4. Evaluate whether the ability of the on-shift staff to perform any required emergency response functions would be degraded or lost prior to the arrival of the augmented ERO.
- 5. Consistent with the site access assumption, evaluate the ability of the augmented staff to implement Transition Phase coping strategies performed after the end of the "no site access" time period.

ASSUMPTIONS OF THE ELAP ERO STAFFING ASSESSMENT
- 1. The ELAP event occurs during off-normal work hours at a time when augmented ERO responders are not at the site (e.g., during a backshift, weekend or holiday).
This analysis uses 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> as the time period to conduct the on-shift ERO response actions. See assumption 13.A below.
- 2. Only personnel required to be on-shift are credited in the staffing analysis. Interim minimum on-shift staffing reductions allowed by Technical Specifications and/or Technical Requirements Manual are not invoked for the study.
NRC LAR approval and SER letter dated 04/25/07 is established as the approved licensing basis for the on-shift staffing complement.
TVA-REP Revision 104 Appendix A Figure A-2, Minimum Onshift Personnel, contains the illustration and listing of BFN minimum shift staffing positions.
TVA-REP Revision 104 Section 3.2.4 contains the requirement for staffing of the corporate Operations Duty Specialist minimum staffing position.
The minimum shift total is obtained by adding shift staffing positions that do not contain a footnote reference in the far right column.

- 5. The extended loss of AC power affecting all units assumes the following:
Appendix "R" emergency lighting is available during period of power loss.
The security emergency diesel generator (EOG) is unavailable.
PA is not powered, but sound powered phones are available.
Credit for plant radios (Harris Radios) is taken as a means of reliable communications throughout the plant for the first 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
BFN can cross connect batteries to extend plant radio capability by keep the batteries charged.
Power operated door locks fail unlocked on loss of power.
Satellite phones available for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.
- 6. A hostile action directed at the affected site does not occur during the period that the site is responding to the event.
- 7. The on-shift staff possesses the necessary Radiation Worker qualifications to obtain normal dosimetry and to enter Radiologically Controlled Areas (but not high, locked high or very high radiation areas) without the aid of a RP Technician.
- 8. The on-site security organization is able to satisfactorily perform tasks related to Site and Protected Area Access Controls. Performance of this function is regularly analyzed through other station programs and will not be evaluated here, unless a role or function from another major response area is assigned as a collateral duty.
The use of Security personnel for any mitigation actions must be in accordance with NEI guidance. (Refer to Attachment 1 Reference #4)
- 9. Individuals holding the position of RP Technician or Chemistry Technician are qualified to perform the range of tasks expected of their position.
- 10. The task of making a simple and brief communication has minimal impact on the ability to perform other assigned functions/tasks, and is therefore an acceptable collateral duty for all positions. Examples include making a plant page announcement or placing a call for assistance to an offsite resource such as local law enforcement. This assumption does not apply to emergency notification to an Offsite Response Organization or the NRC.
- 11. The task of performing a peer check has minimal impact on the ability to perform other assigned functions/tasks, and is therefore an acceptable collateral duty for all positions. Examples include performing a peer check on a recommended emergency classification or notification form for transmittal to offsite authorities.
- 12. For purposes of assessing augmented staffing, it is assumed that the on-shift staff successfully performs all Initial Phase, and any required Transition Phase, coping actions. Thus, adequate core cooling is maintained throughout the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> duration.
No core damage occurs and no entry into Severe Accident Management Guidelines (SAMGs) is required.

- 13. The event impedes site access as follows:
A. Post event time: 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> - No site access. It is assumed that those Emergency Plan functions performed by the augmented ERO will be delayed for the 6-hour period (e.g., field monitoring).
B. Post event time: 6 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> - Limited site access. Individuals may access the site by walking, personal vehicle or via alternate transportation capabilities (e.g.,
private resource providers or public sector support).
C. Post event time: 24+ hours - Improved site access. Site access is restored to a near-normal status and/or augmented transportation resources are available to deliver equipment, supplies and large numbers of personnel.
- 14. All offsite facilities and staging areas are available including those located within the 25 mile telecommunications blackout range.

ON-SHIFT ERO RESPONSE CAPABILITY This section of the assessment documents the ability of the on-shift ERO to implement emergency procedures and coping strategies performed prior to the end of the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> "no site access" time period.
6.1 ELAP Event Description and Initial Conditions A large-scale external event occurs that results in a loss of off-site power combined with a failure of the emergency and security diesel generators to load. The scope of the event includes the following conditions:
an extended loss of AC power (ELAP) event occurs an extended loss of UHS occurs all units are impacted (all units are in operation at the time of the event) station access is impeded Initially, all reactors are operating at full power. Upon the loss of AC power, all three reactors are successfully shut down.
This event results in a Site Area Emergency classification level based on EAL 5.1-S which escalates to a General Emergency classification level based on EAL 5.1-G once it has been determined that power cannot be restored before the coping time will be exceeded (i.e., an ELAP). The scenario is designed such that restoration of any installed (non-FLEX) AC power source is not possible before the arrival of ERO personnel (360 minutes).
Initial Conditions All units 100% power at equilibrium, end of core life.
Scenario Events An extreme external event causes an electrical transient resulting in a loss of all offsite power.
None of the non-FLEX EDGs can be synchronized to any Unit 1, Unit 2 or Unit 3 AC bus, resulting in a tri-unit loss of all AC power.
Adequate core cooling is maintained throughout the 6-hour duration. No core damage occurs and no entry into SAMG is required.
No abnormal radiological conditions exist during this event.
Note - refer to Attachment 1 for a list of procedures used to assess the tasks performed during the ELAP scenario.

Table 7-1 below documents the required site augmented (non on-shift) ERO staffing positions from Table A-1 of NP-REP Appendix A. The recommended depth for each augmented ERO minimum and full staffing positions is 4 per NPG-SPP-18.3, Emergency Preparedness. The number qualified is based on the BFN ERO Qualification Rosters dated 01/09/15.

- 1. Implementing Strategy for the Expanded ERO The ERO augmentation process consists of an "all call/all come" expectation. When the ERO notification systems are operable, the qualified ERO members are contacted and expected to report if fit for duty.
When the normal ERO notifications systems are not operable NPG-SPP-18.3, Emergency Preparedness, includes the following statement under ERO Expectations:
During events that would impact the safe operation of a NPG site (BFN, SQN, or WBN) or large scale disasters (earthquakes, tornados, or regional blackout),
when the ERO has not been activated and area communications (pagers, cell towers, internet, land line phone systems) are being challenged or are not working, NPG ERO personnel are expected to report to their Emergency Response Facility if they cannot contact the plant for additional guidance.
This requirement and expectation was communicated to augmented ERO personnel as well as on-shift ERO personnel (off-duty Operations and Security personnel, and craft personnel) via EP News Letter, e-mail and Electronic Read training for the TVA fleet.
Review of the BFN ERO roster confirmed that sufficient numbers of qualified individuals are available to fill the positions in Table 7.2 with adequate depth to staff at least two 12-hour shifts.
- 2. Response Timeliness for the Expanded ERO The BFN ERO augmentation process consists of an "all call/all come" expectation.
Callout of an expanded ERO is subsumed within the callout of the augmented ERO per NPG-SPP-18.3, Emergency Preparedness.
In the absence of the call out system, ERO members are trained to respond automatically per NPG-SPP-18.3 as described in the implementing strategy above.
- 3. Work Location for the Expanded ERO If access to the primary emergency response facilities is not possible, ERO members are trained to report to their alternate location at the Muscle Shoals Facility.

- 4. Transportation for the Expanded ERO In Tennessee Valley Authority letter to the NRC dated June 11, 2012, Ninety-Day Response to Recommendation 9.3 of 1 O CFR 50.54(f) Request for Information, BFN stated that the following methods of access to the site are available:
Roadway - There are three (3) directions into the BFN:
From Athens/Huntsville/Decatur - Highway 31 onto Nuclear Plant Road into BFN From Athens - State Route 72 to Browns Ferry Road turn right onto Nuclear Plant Road into BFN From Florence - State Route 72 to Shaw Road into BFN Air - Access to BFN can be provided from staging areas and landing zones via helicopters owned by TVA.
Water - BFN can be accessed from the Tennessee River. The Tennessee River can be accessed from multiple access points.
- 5. ERO Drill & Exercise Program NEI 12-01 states that a licensee should determine if any changes are necessary to documents describing the emergency response drill and exercise program. In particular, standard objectives and extent-of-play may need to be revised to clarify the expected demonstration of functions that are dependent upon the type of scenario event or accident (i.e., within or beyond design basis, and number of affected units). For example, functions associated with an expanded response capability would not be demonstrated during a drill or exercise that involved a design basis accident affecting only one unit.
Current BFN drill and exercise procedures include evaluation objectives and demonstration criteria for dual unit events and expanded ERO activities. As future guidance is expected from the NRC in this area, no further changes are necessary to the drill and exercise procedures at this time.

BFN NEI 12-01 Phase 2 ELAP ERO Staffing Analysis Report 7.1.2 Position Specific ERO Response
- 1. Radiation Protection Technicians (RPTs)
The equation below was used to determine the required number of on-site RP Technicians (on-shift plus augmented ERO RP Technicians that perform on-site response functions) for BFN:
RPT TOTAL = RPT COP + RPT SHIFT + RPT RCA + RPT NC Where:
RPT r =Total required number of on-site RP Technicians.
RPT coP = Number needed to support implementation of the 2 most limiting ELAP FLEX strategies.
RPT sH1FT = Number needed to fill on shift complement.
RPT RCA= Number needed for repair and corrective action (x the number of units).
RPT Nc = Number of on-site RP Technicians performing other emergency plan functions that would preclude them from performing job coverage for extended loss of all AC power coping, repair or corrective action teams.
For BFN, the resulting number of RPTs is:
RPT Catego!l'.
RPTcoP RPTsH1FT RPT RCA RPTNc RPT1 Number Reguired 0
2 6
6 14 Comments Staffing assessment results indicate that 0 RPTs are needed to support implementation of the 2 most radiologically limiting ELAP FLEX strategies (see Section 7.1.2.3).
Minimum# of BFN on-shift RPTs.
Minimum #of BFN RPTs required for ERO augmentation response for in-plant RP protective action function (2 x 3 = 6).
Minimum# of BFN RPTs required for ERO augmentation response for radiological assessment function.
Thus, the total number of on-site RPTs required for the expanded ERO is 28 which is based on the staffing needed to:
- 1) Support the two most limiting RP resource intense FSls which do not require rotating shifts (0 RPT cop)
- 2) Support operating on 12-hour shifts for other RP tasks (2 shifts of RPT RcA, RPTsH1FT and RPT Nc = 28 total RPTs).
40 RPTs are available to support performance of assigned emergency plan functions and the expanded response capability (refer to Table 7-1 ).
Provisions exist for obtaining additional RPT resources from other stations within the TVA fleet and/ or within the industry (i.e., INPO Emergency Resource Manual).

- 2. Administrative Support Personnel NEI 12-01 states that a licensee should determine if current assignments and locations of administrative support personnel are adequate for implementation of the expanded response capability, and identify necessary changes.
The administrative support personnel who assist the augmented ERO members are not assigned critical response tasks. Augmented ERO personnel are capable of performing their assigned tasks and responsibilities without requiring administrative support.
- 3. FSI Implementers The assessment considered the number of personnel required for simultaneous implementation of the two FSI strategies for each unit that require the greatest number of staff to implement. There are five (5) FSI strategies for the site:
- 1) Maintain Instrumentation
- 3) RCS Injection
- 4) Containment Integrity
- 5) Spent Fuel Pool (SFP) Makeup & Cooling Based on the FSI task analysis, the following two FLEX strategies have been selected :
Strategy #2 - Decay Heat Removal or #3 - RCS Injection Strategy #5 - SFP Makeup & Cooling Implementation of Strategy #2 or #3 requires FSls to be implemented, and will require the following personnel resources:
Strategy #2 - Decay Heat Removal or #3 or RCS Injection Implementation of Strategy #2 or #3 involves the following FSls and personnel resources:

The overall responsibility for the site response will be maintained by a single Site Emergency Director. This individual will provide overall command & control to the augmented ERO for the site and allow for an integrated site response. The augmented ERO positions of TSC Operations Manager
& TSC Technical Manager will also be staffed by a single individual for the site. The Operations Manager will coordinate with the Operations Shift Manager & the three (3) Unit Supervisors to manage the response to a BDBEE. The TSC Technical Manager will coordinate the overall response of the Technical Assessment Teams for each unit in order to support 24-hour expanded ERO staffing based on 12-hour shifts. Implementation of the two most limiting FSI tasks (last row) does not require 24-hour coverage. The number available column is the number of personnel qualified to the position.
