UNITED STATES NUCLEAR REGULATORY COMMISSION REGION II 245 PEACHTREE CENTER AVENUE NE, SUITE 1200 ATLANTA, GEORGIA 30303-1257 January 15, 2013 Mr. Mano Nazar Executive Vice President and Chief Nuclear Officer Florida Power and Light Company P.O. Box 14000 Juno Beach, FL 33408-0420

SUBJECT:

ERRATA ST. LUCIE NUCLEAR PLANT UNIT 1 - NRC INSPECTION PROCEDURE 95002 SUPPLEMENTAL INSPECTION REPORT 05000335/2012009 AND ASSESSMENT FOLLOW-UP LETTER FOR ST. LUCIE NUCLEAR PLANT UNIT 1 On November 16, 2012, the US Nuclear Regulatory Commission (NRC) issued the subject inspection report for St. Lucie Unit 1, ADAMS accession ML12321A239. The inspection and closure of a licensee event report (LER) entitled Unit 1 Reactor Trip on Turbine Trip was documented in the inspection report. The LER was incorrectly assigned the tracking number 05000335/2012-007-0. The correct LER tracking number is 05000335/2012-005-0.

Accordingly, we have revised pages 4 and 14 of the enclosure to Inspection Report 05000335/2012009 in order to document the necessary changes. Please replace pages 4 and 14 of the enclosure to the original report with the pages enclosed.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). The original report is available at ML12321A239. ADAMS is accessible from the NRC Web site at http://www.nrc.gov/readingrm/adams.html (The Public Electronic Reading Room).

I apologize for any inconvenience this error may have caused. If you have any questions, please contact me at (404) 562-4513.

Sincerely,

/RA/

Shane Sandal, Acting Chief Projects Branch 3 Division of Reactor Projects

REPORT DETAILS

4. OTHER ACTIVITIES 4OA3 Follow-up of Events and Notices of Enforcement Discretion

.1 (Closed) Licensee Event Report (LER) 05000335/2012-003-00, 01, Manual Trip during Steam Bypass Control System Post-Modification Testing On March 31, 2012, while St. Lucie Unit 1 was at 10 percent reactor power and the licensee was performing preoperational testing of the SBCS, the reactor was manually tripped when a steam bypass control valve unexpectedly opened. Immediately following the reactor trip, the steam bypass control valve closed. Additionally, operators closed the main steam isolation valves in accordance with Emergency Operating Procedure (EOP-01), "Standard Post Trip Actions" due to steam generator pressure decreasing to less than 750 psia. During post trip recovery, EOP-05, "Excess Steam Demand" was entered as a result of not meeting Reactor Coolant System (RCS) average temperature between 525 and 535 degrees. EOP-05 was exited with no actions taken when temperature increased into the required band. The licensee documented this issue in the corrective action program as action request (AR) 1755493-01. The enforcement aspects associated with this LER are dispositioned in Section 4OA4.2.01 d.

.2 (Closed) LER 05000335/2012-005-00, Unit 1 Reactor Trip on Turbine Trip On June 2, 2012, Unit 1 automatically tripped from normal full power operation due to a turbine trip and loss of load following a failure of the TCS. There were no complications with the reactor trip. The reactor trip on turbine trip was caused by loss of communications in the recently installed Ovation TCS due to a failed fiber optic connection. The licensee documented this issue in the corrective action program as AR 01772644. The enforcement aspects associated with this LER are dispositioned in Section 4OA4.2.01 d.

4OA4 Supplemental Inspection (95002)

.1 Inspection Scope This supplemental inspection was conducted using Inspection Procedure (IP) 95002 to assess the licensees RCE associated with the four unplanned reactor trips described below that resulted in a degraded Initiating Events cornerstone in the reactor safety strategic performance area for Unit 1.

  • 3rd Quarter 2011: Manual reactor trip from 100 percent power due to a large influx of jelly fish into the intake canal affecting the circulating water and intake cooling water systems. During the trip recovery, all main feedwater was lost. This was considered a complicated reactor trip. (AR 1679935)
  • 4th Quarter 2011: Manual reactor trip from 100 percent power due to loss of circulating water pumps resulting in decreasing condenser vacuum. (AR 01697977)
