At 0746, on 6/6/2007, a Unit 3 shutdown was initiated in accordance with station procedures. Unit 3 entered
Technical Specification (TS) 3.0.3 at 0745 on 6/6/2007.
TS 3.0.3 was entered when the Analog Rod Position Indicator (ARPI) for control rod F-4 was declared inoperable. Control rod F-4 is located in control bank C. The ARPI for control rod M6, which is also in control bank C, has been previously declared inoperable. With two ARPIs in control bank C inoperable, TS Limiting Condition for Operation 3.1.3.2, Action a, cannot be met thus necessitating entry into TS 3.0.3. ARPI repairs will be performed as required.
The licensee notified the NRC Resident Inspector.

Turkey Point Unit 3 entered Mode 3 at 1152 on 6/6/07 after manually tripping from approximately 25% power. At 1152 Turkey Point exited TS 3.0.3 since the condition for which it was entered no longer applied. The site borated to compensate for the control rods for which position indication was lost.
All control rods fully inserted on the trip. The plant is currently steaming to atmospheric relief valves. No primary to secondary tube leaks exist.
The licensee will notify the NRC Resident Inspector. Notified R2DO (Fredrickson).
