St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 Revised Technical Specifications for License Amendment Request for Adoption of Technical Specifications Task Force (TSTF) Traveler TSTF-422, Revision 2, "Change in Technical Specifications End States, (CE NPSD-1186)," Using the Consolidated Line Item Improvement Process L-2016-132 10 CFR 50.90 1. FPL Letter L-2015-182 dated August 31, 2015, "License Amendment Request for Adoption of Technical Specifications Task Force (TSTF) Traveler TSTF-422, Revision 2, 'Change in Technical Specifications End States, (CE NPSD-1186),'

Using the Consolidated Line Item Improvement Process," ADAMS Accession No. ML15084A141 In Reference 1 Florida Power & Light (FPL) submitted a Technical Specification (TS) license amendment request (LAR) that would utilize risk-informed requirements to modify selected Required Action End States. Based on teleconferences between the Staff and FPL, FPL is submitting some revised TS markups and their corresponding word-processed TSs. The attachment contains the justification for the proposed changes. The revised TSs replace those provided in Reference

1. The no significant hazards consideration determination within Reference 1 bounds the scope of these changes. If you should have any questions, please contact Mr. Ken Frehafer at (772) 467-7748. I declare under penalty of perjury that the foregoing is true and correct. Executed on JUL 1 5 2016 Sincerely, Christopher R. Costanzo Site Vice President St. Lucie Plant CRC/KWF Attachment cc: NRC Region II Administrator St. Lucie Plant NRC Senior Resident Inspector 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. 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). FPL is providing replacement proposed markups and word processed TSs that address the above inconsistencies.

PLANT SYSTEMS 3/4.7.7 CONTROL ROOM EMERGENCY VENTILATION SYSTEM LIMITING CONDITION FOR OPERATION 3.7.7.1 The control room emergency ventilation system shall be OPERABLE with: a. Two booster fans, b. Two isolation valves in each outside air intake duct, c. Two isolation valves in the toilet area air exhaust duct, d. One filter train, e. At least two air conditioning units, and f.
