TEXAS AGREEMENT STATE REPORT
The following information was received from the State of Texas via email:
"While removing gauges from the vessels they were attached to, in response to an investigation into a source disconnect on a different gauge [see EN #44609], the licensee found that a second source had separated from its operating rod and was located inside the insertion well. The source will remain in the well until its removal can be scheduled. The area has been isolated. Since the source separated inside the insertion well near its normal operating position, there was no additional exposures to members of the public. Two similar gauges were closed, removed from their mountings, and placed in storage. Four other devices containing radioactive sources have been closed and the shutters locked. Surveys have been completed to verify the sources are inside these gauges.
"The gauge involved is a Thermo Measure Tech Model 5191 level measurement gauge serial number B45, containing a 253.4 milliCuries (decay corrected) Cesium (Cs) - 137 source serial number B45.
"The licensee stated that they had informed the State of the event on 11/26/08."
Texas Report No. I-8594

AUTOMATIC REACTOR SCRAM DUE TO EHC MALFUNCTION
"At 12:00 hours EST, an apparent Electro-Hydraulic Control (EHC) system malfunction while synchronizing the Main Generator to the grid resulted in a Group 1 Main Steam Isolation Valve (MSIVs) closure on low reactor pressure and a subsequent automatic reactor scram.
"Preliminary investigation of the automatic scram signal indicates that Main Steam Line Low Pressure Instruments (B21-PT-N015 A thru D) sensed low steam line pressure after the Main Generator was paralleled to the grid. This resulted in the closure of all MSIVs. Closure of MSIVs in Mode 1 results in an automatic reactor scram.
"All control rods fully inserted. With the exception of the EHC system, all systems responded as designed. This report is being made in accordance with 10 CFR 50.72(b)(2)(iv)(B) due to the Reactor Protection System (RPS) actuation and 10CFR 50,72(b)(3)(iv)(A) due to the Primary Containment Isolation System (PCIS) Groups 1, 2, and 6 actuations.
"Unit 2 was not affected by this event and remains at 100% power."
Reactor Pressure is 844 psig, reactor temperature is 526 degrees Fahrenheit. MSIV's remain shut. Decay heat was removed via MSIV bypass lines. RCIC actuated for a period of time for level control but has been secured. CRD pumps are providing makeup water. No SRV's or relief valves lifted.
The NRC Resident Inspector has been notified.
