L-2016-132 Attachment Page 1of5 Some of the original FPL-proposed TS changes were not consistent with the changes authorized by TSTF-422. Specifically: | |||
: 1. One of the TSTF-422 assumptions was that the control room emergency ventilation system filter subsystem consists of two independent trains. Although the Unit 1 Control Room Emergency Ventilation System has only one filter train, FPL applied the HOT SHUTDOWN end state in the original TS markups for TS 3.7.7.1.c. Because applying the HOT SHUTDOWN end state for loss of the Unit l's CREVS single filter train could be considered non-conservative, FPL is withdrawing the originally proposed HOT | |||
* SHUTDOWN end state proposal from TS 3/4.7.7.1 Action c. | |||
Specifically: | : 2. FPL originally proposed a HOT SHUTDOWN end state for a Unit 2 de-energized AC instrument bus in TS 3/4.8.3 action b(l), even though this proposal had no counterpart in TSTF-422. Therefore, FPL is withdrawing the originally proposed HOT SHUTDOWN end state from TS 3/4.8.3 Action b(l). | ||

- 1. One of the TSTF-422 assumptions was that the control room emergency ventilation system filter subsystem consists of two independent trains. Although the Unit 1 Control Room Emergency Ventilation System has only one filter train, FPL applied the HOT SHUTDOWN end state in the original TS markups for TS 3.7.7.1.c.

- 2. FPL originally proposed a HOT SHUTDOWN end state for a Unit 2 de-energized AC instrument bus in TS 3/4.8.3 action b(l), even though this proposal had no counterpart in TSTF-422. Therefore, FPL is withdrawing the originally proposed HOT SHUTDOWN end state from TS 3/4.8.3 Action b(l).
