These changes meet the NEI 12-06 compliance method.
4.1 General Integrated Plan Elements, Section 4, changed as follows:
Moved item previously numbered Item 25 to Item 22. The item states:
Calculation MDQ0003602014000222 (Ref. 4c) specifies manual actions needed to ensure acceptable room temperatures. 0-FSI-4A (Ref. 13j) will establish the required ventilation.
This is required by the referenced calculation which states the temporary ventilation will be established by T+20 hours. All subsequent items were renumbered.
4.2 General Integrated Plan Elements, Section 4, Item 11, changed to read as follows:
Dispatch personnel to start deployment of the 480V FLEX Generator or, in the event the 480V FLEX Generators are unable to supply the safety related 250V Unit Battery Chargers, dispatch personnel to start deployment of the 4kV FLEX Generators.
(Note: the 480V FLEX Generator will have already been deployed for a flood event, see Item 3).
4.3 Maintain Core Cooling, Section 11 BWR Portable Equipment Phase 2, second bullet, changed to read as follows:
Two 4kV FLEX Support Generators, temporary cable, and equipment necessary for connection will be staged in the FESB. The 4kV generators may be used to energize the safety related 4kV and 480V distribution systems to supply ventilation, pump motors, fan motors, and motor operated valves as needed. For non-flood events, the generators will be available for staging adjacent to the U1/2 or the U3 Diesel Buildings (Attachment 3, Figure 3) and connected directly to the output of any selected Emergency Generator to energize the 4kV distribution system. For expected flood conditions the generators will be pre-staged at either of two staging areas above the 578 maximum flood elevation (Attachment 3, Figure 3). These temporary connections to the 4kV distribution system will be made through either the 1B or 3B 4kV Unit Boards. (Refer to Attachment 3, Figure 1B). In the event that the 480V FLEX Generators are unable to supply the safety related 250V Unit Battery Chargers, an additional strategy to supply the chargers is available using the 4kV FLEX Support Generators. Procedures (Ref. 13a, 13l) have been written directing performance of this additional strategy if required.
Page 3 of 13
4.4 Maintain Spent Fuel Pool Cooling, Section 17 BWR Portable Equipment Phase 2, second bullet, changed to read as follows:
Two 4kV FLEX Support Generators, temporary cable, and equipment necessary for connection will be staged in the FESB. The 4kV generators may be used to energize the safety related 4kV and 480V distribution systems to supply ventilation, pump motors, fan motors, and motor operated valves as needed. For non-flood events, the generators will be available for staging adjacent to the U1/2 or the U3 Diesel Buildings (Attachment 3, Figure 3) and connected directly to the output of any selected Emergency Generator to energize the 4kV distribution system. For expected flood conditions the generators will be pre-staged at either of two staging areas above the 578 maximum flood elevation (Attachment 3, Figure 3). These temporary connections to the 4kV distribution system will be made through either the 1B or 3B 4kV Unit Boards. (Refer to Attachment 3, Figure 1B). In the event that the 480V FLEX Generators are unable to supply the safety related 250V Unit Battery Chargers, an additional strategy to supply the chargers is available using the 4kV FLEX Support Generators. Procedures (Ref. 13a, 13l) have been written directing performance of this additional strategy if required.
4.5 Attachment 1A, Sequence of Events Timeline, changed as follows:
Moved item previously numbered Item 25 to Item 22. The item states T+20 hours / Manual actions to restore ventilation (if normal ventilation is not restored) by opening doors, portable fans, etc. / Y / Time based on BFN calculation MDQ0003602014000222. 0-FSI-4A will establish required ventilation.
All subsequent items were renumbered.
5 Need for Relief/Relaxation and Basis for the Relief/Relaxation TVA requested and received relaxation from full implementation until the completion of the spring 2017 refueling outage for BFN Unit 2 and the spring 2018 refueling outage for BFN Unit 3 to allow sufficient time to implement a severe accident capable hardened containment wetwell vent (References 8 and 9 in Section 8). The Milestone Schedule (Section 3 and Attachment 2) has been revised to reflect this relaxation.
