By letter L-2010-004 dated July 16, 2010 [Reference 1], Florida Power and Light (FPL) Company requested an amendment to Facility Operating Licenses DPR-31 and DPR-41 for Turkey Point Units 3 and 4 Technical Specifications (TS). The proposed amendment would modify the TS requirements related to control room envelope habitability in accordance with Technical Specification Task Force (TSTF) Change Traveler TSTF-448 Revision 3, "Control Room Habitability."

On June 16, 2011, FPL received Requests for Additional Information (RAI) via email [Reference 2]

from the U.S. Nuclear Regulatory Commission (NRC) Project Manager (PM) containing five questions regarding License Amendment Request (LAR) No. 194, Control Room Habitability TSTF-448. On July 18, 2011, FPL provided it responses to the RAI via letter L-2011-264 [Reference 3].

Turkey Point Units 3 and 4 L-2011-276 Docket Nos. 50-250 and 50-251 Page 2 of 2 Discussions between FPL and the NRC PM just prior to the approval of LAR No. 196 revealed some additional clarification to TS 3.7.5 Action a.5 was still needed. However, it was agreed that such changes would be addressed as part of LAR No. 194 to preclude further delay in issuance of the AST amendments. The requested clarification to TS 3.7.5 Action a.5, as approved under LAR No. 196, is presented with the TSTF-448 proposed changes in the Attachment to this letter.

The Turkey Point Plant Nuclear Safety Committee has reviewed the proposed changes to the Technical Specifications and has concluded that the changes do not involve a significant hazards consideration. This submittal does not alter the significant hazards consideration previously submitted by FPL letters L-2010-004 [Reference 1] and L-2010-083 [Reference 5] nor does it alter the enviromnental assessment previously submitted by FPL letter L-2009-133 [Reference 4].

This submittal contains no new commitments and no revisions to existing commitments.

In accordance with 10 CFR 50.91 (b)(1), a copy of this letter is being forwarded to the State Designee of Florida.

Should you have any questions regarding this submittal, please contact Mr. Robert J. Tomonto, Licensing Manager, at (305) 246-7327.

-Docket Nos. 50-250 and 50-251 Attachment Page 2 of 13 Supplemental Response Regarding LAR No. 194 Control Room Habitability TSTF-448 By letter L 2010-004 dated July 16, 2010 [Reference 1], Florida Power and Light (FPL) Company requested an amendment to Facility Operating Licenses DPR-3 I and DPR-41 for Turkey Point Units 3 and 4 Technical Specifications (TS). The proposed amendment would modify TS requirements related to control room envelope habitability in accordance with Technical Specification Task Force (TSTF) Change Traveler TSTF-448 Revision 3, "Control Room Habitability."

On June 16, 2011, FPL received Requests for Additional Information (RAI) via email [Reference 2]

from the U.S. Nuclear Regulatory Commission (NRC) Project Manager (PM) containing five questions regarding License Amendment Request (LAR) No. 194, Control Room Habitability TSTF-448. On July 18, 2011, FPL provided it responses to the RAI via letter L-2011-264 [Reference 3].

The proposed amendment would revise Control Room Emergency Ventilation System (CREVS) TS 3.7.5, Limiting Conditions for Operation (LCO), Action Statements, Surveillance Requirements (SR), and add new administrative program requirements on Control Room Habitability to TS 6.8.4.

By letter L-2009-133 dated June 25, 2009 [Reference 4], FPL requested an amendment to Facility Operating Licenses DPR-31 and DPR-41 for the Turkey Point (PTN) Units 3 and 4 TS. The proposed amendments revise the TS in order to adopt the alternative source term (AST) as allowed in 10 CFR 50.67. On June 23, 2011, the NRC approved AST LAR No. 196 and issued License Amendment Nos. 244 and 240 for PTN Units 3 and 4, respectively [Reference 5].

Discussions between FPL and the NRC PM just prior to the approval of LAR No. 196 revealed some additional clarification to TS 3.7.5 Action a.5 was still needed. However, it was agreed that such changes would be addressed as part of LAR No. 194 to preclude further delay in issuance of the AST amendments. The requested clarification to TS 3.7.5 Action a.5, as approved under LAR No. 196, combined with the TSTF-448 proposed changes is presented below.

TS 3.7.5 LCO. ACTIONS, and SRs A revision to the proposed wording in TS 3.7.5 ACTION a.5 is provided to clarify the specific actions to be taken when the filter train is inoperable for reasons other than an inoperable CRE boundary, e.g., the compensatory filtration unit is to be placed into service if the filter itself is inoperable. The proposed TSTF-448 changes to the TS 3.7.5 LCO, Actions, and Surveillance Requirements, as approved for LAR No. 196 Alternative Source Term (Amendments 244 and 240), are shown in Figure 1.
