MISSISSIPPI AGREEMENT STATE REPORT: TROXLER GAUGE RUN OVER BY A BULLDOZER.


On 06/21/04 at 1800 CDT an Alabama licensee, Gallet Associates, had one of their Troxler gauges; Model # 3401, gauge serial number 12283; run over by a bulldozer in Flowood, Mississippi. The rod was broken off. Surveys taken of the rod was 10 mRem/hr at one foot. The gauge has been stored and the licensee will call Troxler. The gauge contained 8.6 milliCuries of Cesium-137 and 40 milliCuries of Am-241/Be.

State of Mississippi assigned event for this incident is MS-04-005

* * * UPDATE VIA EMAIL FROM B. SMITH TO JEFF ROTTON AT 1205 EDT ON 07/08/04 * * *

"Damaged gauge and Cesium-137 source picked up by AEA Technology (QSA) from Mississippi Division of Radiological Health office for transport back to AEA facility located in Baton Rouge, LA. AEA will handle disposal of sources."

Notified R1DO (Holody) and NMSS EO (Essig).

AGREEMENT STATE REPORT REGARDING WELL LOGGING SOURCE ABANDONMENT BY STATE LICENSEE

Texas Incident #: I-8136

Event Location: Hidalgo County, Texas(TDH, Public Health Region 11) at the Guerra #25 operated by Edge Petroleum

API #: 42-215-33214

On July 4, 2004, the Licensee notified this Agency of the loss of three radioactive sources on a well logging tool-string in Hidalgo County, Texas, at the Guerra #25 well (API # 42-215-33214) operated by the Edge Petroleum Company. The string contained three sources, manufacturer and Serial Nos. are not available at this time. The sources are: 0.8 microcurie Cs-137; 2.5 curie Cs-137; and an 18 curie Am-241/Be. The sources are abandoned in a well with a total depth of 9,034 feet. The top of the tool-string is located at 5,697 feet and fishing attempts have not allowed recovery. A minimum of 200 feet of red tagged cement has been poured to secure the string in place. Negotiations with the Texas Railroad Commission continue for the placement of a deflection device in the well. The Licensee will be ordering a plaque for emplacement on the wellhead.

REACTOR SCRAM DUE TO A TURBINE GENERATOR LOAD REJECTION SIGNAL

The following information was received from the licensee via facsimile:

"On 7/08/2004 at approximately 2232 hours CDT, Browns Ferry Unit 2 scrammed due to a Turbine Generator Load Reject Signal. All systems responded as required to the scram signal. No ECCS initiations occurred as a result of this event. Reactor Water Level lowered to the Low Level setpoint which generated a redundant SCRAM signal and initiated the Primary Containment Isolation System (PCIS) function for PCIS groups 2 (Primary Containment), 3 (RWCU) [Reactor Water Clean Up], 6 (Secondary Containment), and 8 (TIP system) [Transverse Incore Probe]. As expected, Main Steam Relief Valves (MSRVs) opened due to the high reactor pressure (maximum value observed was 1137 psig) as a result of the Main Turbine / Generator Trip. Reactor Water level was restored to normal via the Reactor Feedwater system and all PCIS isolations have been reset. The cause of the Load Reject Signal is still under investigation at this time.

"This event is reportable under 10CFR50.72(b)(2)(iv)(B), 'Any event or condition that results in a valid actuation of the Reactor Protection System (RPS) when the reactor is critical' and also under 10CFR50.72(b)(3)(iv)(A), 'Any event or condition that results in a valid actuation of any of the systems listed in paragraph (b)(3)(iv)(B)'. This event also requires a 60 day written report in accordance with 10CFR50.73(a)(2)(iv)(A)."

All control rods inserted during the scram. All Main Steam Relief Valves have properly reset. Decay heat is being removed from the reactor via main turbine bypass valves to the main condenser. Pressure is being maintained at normal operating pressure. The electrical grid is stable. Unit 3 was not affected by the scram on Unit 2.

The licensee has notified the NRC Resident Inspector.
