UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Mr. Mano Nazar President and Chief Nuclear Officer Nuclear Division Florida Power & Light Co.
Mail Stop NT3/JW 15430 Endeavor Drive Jupiter, FL 33478 October 18, 2016
SUBJECT:
ST. LUCIE PLANT, UNIT NOS. 1 AND 2 - CORRECTION TO AMENDMENT NOS. 236 AND 186 REGARDING USE OF NEW COMPUTER CODE TO MODEL THE CONTAINMENT VACUUM ANALYSES (CAC NOS. MF6980 AND MF6981)
Dear Mr. Nazar:
On October 5, 2016, the U.S. Nuclear Regulatory Commission (NRC, the Commission) issued Amendment Nos. 236 and 186 to the St. Lucie Plant, Units Nos. 1 and 2, Renewed Facility Operating License Nos. DPR-67 and NPF-16, respectively (Agencywide Documents Access and Management System (ADAMS) Accession No. ML16166A424). The amendments updated the St. Lucie Plant, Units Nos. 1 and 2, Technical Specifications (TSs) to reflect the use of "Generation of Thermal Hydraulic Information for Containments (GOTHIC Version 7.2b(QA))"
containment vacuum analyses computer code. The amendments also updated the St. Lucie Plant, Units Nos. 1 and 2, TSs to credit the design-basis ability of the containment vessel to withstand a higher external pressure differential of 1.04 pounds per square inch (psi) for Unit No. 1 and 1.05 psi for Unit No. 2, and updated TS 3.6.1.4 for both units to revise the allowable containment operating pressure range.
Specifically, Unit No. 1 TS page 3/4 6-12 and Unit No. 2 TS page 3/4 6-11 were updated by Amendment Nos. 236 and 186. These two TS pages were recently updated when Amendment Nos. 234 and 184 were issued on August 30, 2016 (ADAMS Accession No. ML16210A374).
However, in issuing Amendment Nos. 236 and 186, the NRC staff inadvertently included TS pages that did not reflect changes for Amendment Nos. 234 and 184.
Enclosed are the corrected Unit No. 1 page 3/4 6-12 and Unit No. 2 page 3/4 6-11 to replace the corresponding pages issued by Amendment Nos. 236 and 186 for the St. Lucie Plant. This correction does not change any of the conclusions in the safety evaluation associated with the amendments.
If you have any questions regarding this matter, please contact me at (301) 415-1383 or Perry.Buckberg@nc.gov.
