ENCLOSURE 1 Tennessee Valley Authority Browns Ferry Nuclear Plant, Units 1, 2, and 3 Revised Response to Safe Shutdown Analysis Request for Additional Information 15 Safe Shutdown Analysis (SSA) Request for Additional Information (RAI) 15 TVA previously responded to SSA RAI 15 by letter dated January 14, 2014 (CNL-14-006). TVA determined there is an exception for statements made regarding the concurrent use of Emergency Operating Instructions (EOIs) with the NFPA 805 Fire Safe Shutdown procedures.

The BFN NFPA 805 Fire Safe Shutdown procedures for Main Control Room (MCR) abandonment will not be linked to the EOIs (i.e., used concurrent with EOIs) because in the Primary Control Station environment, use of EOIs is not feasible or practical. Identification of this exception also affected statements made in the BFN NFPA 805 LAR Section 4.2.1.1 and Attachment S, Table S-3, Item 25.

BFN NFPA 805 License Amendment Request (LAR) Section 4.2.1.1, Comparison to NEI 00-01 Revision 2, first bullet is revised to as follows.

The additional considerations of Revision 2 will be addressed by linking the Emergency Operating Instructions (EOIs) to fire safe shutdown procedures consistent with the recommendations of a BWROG document, BWROG-TP-11-011, entitled, BWROG Assessments of Generic Multiple Spurious Operations (MSOs) in Post-Fire Safe Shutdown Circuit Analysis for the Operating BWR Plants, dated June, 2011, with the exception of the MCR abandonment Fire Safe Shutdown procedures. The MCR abandonment Fire Safe Shutdown procedures will include procedure steps for fires impacting the ability to scram from the MCR. See Implementation Item 25 in Table S-3 of Attachment S. to this letter provides the revised Attachment S, "Modifications and Implementation Items," Table S-3, "Implementation Items," Implementation Item 25.

The below revised response supersedes the previous response for SSA RAI 15 in its entirety.

The changes from the previous response are shown with deleted text struck through, inserted text in bold, underline, and a revision bar in the right margin.

TVA Revised Response The plan for transition of fire safe shutdown instructions includes migration away from strategies that instruct the operators to take detrimental actions such as intentionally disconnecting offsite power, commonly referred to as Self-Induced Station Blackout (SISBO). With the exception of Main Control Room (MCR) abandonment, Tthe new procedures will be executed concurrently with the symptom based Emergency Operating Instructions (EOIs) and other operating procedures. This is in contrast to the current strategy in the sSafe Shutdown Instructions (SSIs)

CNL-15-191 Enclosure 1, Page 1 of 2

that calls for exiting the EOIs and other operating procedures when the SSIs are entered. The symptom based strategy will allow the operators to use the systems and equipment that are available as opposed to being limited by procedure to a single, predetermined success path.

For MCR abandonment, the Fire Safe Shutdown (FSS) procedure will not be used concurrently with the EOIs which is similar to the current MCR abandonment procedure for non-fire events. The MCR abandonment FSS procedures will include the instructions for transfer of control to the Primary Control Station, the use of credited equipment to meet the Nuclear Safety Performance Criteria as well as the risk and DID recovery actions. The FSS procedure for MCR abandonment will allow the use of offsite power, if available, and will not require SISBO.

The following actions are planned to ensure a smooth transition to new procedures.

1. Preparation and review of new procedures The procedures required to implement the new NFPA 805 Fire Safe Shutdown will be prepared and implemented before NFPA 805 transition. The structure of the procedures will utilize the current EOIs supplemented by FA specific instructions that will include risk and DID recovery actions (or in the case of MCR abandonment, Fire Safe Shutdown procedures with MCR abandonment specific instructions for transfer of control to the Primary Control Station, the use of credited equipment to meet the Nuclear Safety Performance Criteria including the risk and DID recovery actions). These instructions will be similar to the current SSIs that contain actions specific to fires in that area and identify the credited safe shutdown path. Modifications will be in progress while the new SSIsFSS procedures are being implemented, and therefore, revisions to incorporate the modification effects will be a continuous process.
2. Validation of new procedures The new and revised procedures will be validated prior to implementation to ensure they are feasible as written given the plant configuration. The feasibility validation will follow the Frequently Asked Question (FAQ) 07-0030 guidance.
3. Training operators on the new fire shutdown procedure strategy Operator training will be developed using the systematic approach to training. Initial training will be conducted prior to transition addressing the new procedure structure and safe shutdown strategies. Operators will be trained on the effect of modifications on operating procedures, similar to the current training process.

The new procedure strategy is already familiar to the operators because it will utilize the current EOIs for monitoring and controlling critical parameters and utilization of plant systems with the exception of MCR abandonment. For MCR abandonment, the FSS procedure will not be used concurrent with the EOIs which is similar to the non-fire event MCR abandonment procedure. The operation of the systems that is unique to a fire condition, such as the use of recovery actions, will be similar to the way the equipment is currently operated in the SSIs. The new procedure strategy has already been implemented in SSIs for FAs 25-1, 25-2, 25-3 and 26 and operators have received training on the changes.

TVA BFN Attachment S - Modifications and Implementation Items Table S Items provided below are those items (procedure changes, process updates, and training to affected plant personnel) that will be completed prior to the implementation of new NFPA 805 fire protection program. This will occur 180 days after issuance of the license amendment unless that date falls within a scheduled refueling outage. If this is the case, then implementation will occur 60 days after startup from that scheduled refueling outage. Note that Items 32 and 33 are associated with modifications in Table S-2 and will be completed in accordance with the timetable described in the Implementation Item.

Table S-3 Implementation Items Item Unit Description LAR Section / Source 01 1, 2, 3 Implement the results of the Radioactive Release Review: 4.4.2 and Attachment E

a. Within each pre-fire plan that has an access point to a non-RCA area, enhance the pre-fire plan to better identify concerns for radioactive release by incorporating one of the following options:
a. Identifying the RCA in the written text or the pre-fire plan drawings is intended to aid the Incident Commander in avoiding radioactive release. For consistency, it is recommended that hardened barriers be identified.

Examples of these would include: the Unit 1 Reactor Building truck bay hatch, water tight doors to the outside as well as passage doors and roll-up door.

b. Incorporate a descriptive text in the pre-fire plan that highlights escape path concerns specific to that pre-fire plan.
b. Add generic wording to area fire plans to prompt measures to avoid radioactive release.
c. Pre-fire plans with doorways to the outside or to non-RCA areas will be revised and will have the plan drawing revised to include the door and an identification method to allow the BFN-FERO to recognize this as an RCA boundary.
d. Add an appendix to the pre-fire plans for building sump drainage and site storm drains.
e. Develop a standard operating procedure to support actions to prevent radioactive release. This document will stress actions to prevent the escape of potentially contaminated materials from a building or area boundary. Additional guidance will be provided for fires in yard areas and locations with limited or no engineering controls.
f. Develop new pre-fire plans for the following areas:
1. East Access Building CNL-15-191, Enclosure 2 Page 2 of 13

9. Units 1, 2 A and B Chillers (Fire Area 27)
g. Revise the guidance within RWI-001 and/or RWI-111 to address storage of radioactive material for compliance with the radioactive release criteria. The recommended practices would include:
1. A screening process.
2. A boundary process.
3. A source term process.
4. When radioactive materials are handled outdoors and outside of containers that exceed the source term limits, consideration should be given to reducing the potential for a fire to occur.
h. Each fire brigade member will be provided training to identify potential points for radioactive release and the actions that can be taken to mitigate a release. To support the training, guidance will be provided in pre-fire plans and standard operating procedures to outline these expectations and actions.
