AGREEMENT STATE REPORT OF DAMAGED RADIOGRAPHY CAMERA

The State provided the following information via email:

"This is an incident involving a SPEC 150 exposure device with serial number 0288 that contained a 80 Ci source of Ir-192 (SPEC G-60 serial number NA-2006). On March 9, 2006 while radiographing a coupon, the exposure device was placed in contact with a welding lead. When the exposure device was cranked out the crankout cable formed an electrical conductor from the welding lead to the coupon. An arc and smoke was observed. The radiographer immediately returned the source to the shielded position. The radiographer approached the exposure device with a survey meter and determined the source was in the shielded position. The radiographer disconnected the source tube and replaced the safety plug. While attempting to remove the drive cable connector from the source pigtail, the connector came off. The radiographer replaced the dust cover cap, secured the exposure device in the transport container and called the main office. Neither radiographer received an excessive exposure. The exposure device and equipment were sent to SPEC for evaluation. SPEC stated that the integrity of the encapsulated source was not harmed, but the pigtail itself was unusable, and the source had to be disposed. The exposure device operated properly and was cleared for use by SPEC."

AGREEMENT STATE REPORT - STOLEN ALLOY ANALYZER

An alloy analyzer was stolen between 11:00 and 12:00 on 4/6/2006. The device was in Beaumont, TX and the theft was reported to the local police (case number 069751).

Description: Niton model XL 800, serial # U2184
Source: 10 milliCurie Cd-109 (This was the original activity when purchased five years ago), Source model # XFB3205, Serial # NR6244

Texas Incident Number I-8324

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source

UNIT 1 MANUALLY TRIPPED DUE TO FAILURE OF A MAIN FEED REGULATING VALVE TO CONTROL STEAM GENERATOR LEVEL

"Unit 1 reactor was manually tripped from 33% RTP due to the Loop 3 Main Feed Regulating Valve (MFRV) 1LV-0530 not controlling steam generator level in manual or AUTO.

"A unit shutdown was in progress at the time of the trip due to concerns with the Loop 3 MFRV. The unit shutdown had commenced from 100% power on 04/16/2006 at 1603 hrs.

"All systems functioned as required on the reactor trip including a feedwater isolation and the Loop 3 MFRV closing as expected. The unit is presently in Mode 3 at normal operating temperature and pressure. An investigation team is being assembled concerning the Loop 3 MFRV."

All control rods fully inserted. No primary or secondary reliefs/safeties lifted during the transient. Unit 1 is currently in Mode 3 Hot Standby controlling Steam Generator Water Level using Auxiliary Feedwater supplied by both Motor Driven and the Steam Driven pumps. Decay Heat is being removed via the Bypass Valves to the Main Condenser. Offsite power is stable and all EDGs are available, if necessary.

The licensee informed the NRC Resident Inspector.
