AGREEMENT STATE REPORT - LOST Cs-137 SOURCE HOLDER

"Ohmart-VEGA RSO was informed on 11/14/07 that a shipment of SR-1A source holders sent to Gibraltar Mines in McLeese Lake, BC, Canada has been lost in transit. The missing consignment consists of 5 devices, each containing 100 mCi of Cs-137. The shipment left the Ohmart facility on 10/25/07. The Ohmart representative in Canada [DELETED] is leading the effort to locate the missing shipment. [DELETED] of the CNSC was notified by Canadian Freightways personnel on 11/14/07.

"TST Overland confirms turning over (2) skids to Canadian Freightways on Oct 29, 2007 in Burnaby, BC for furtherance to McLeese Lake, BC. One skid containing detectors was delivered to the customer in McLeese Lake. [DELETED] was unaware of this missing item until he received a phone call from the customer. He is pressing the trucking company to locate the equipment.

"Timeline as currently known:
TST-Overland picked up two skids at Ohmart-Vega in Cincinnati, OH on 10/25/07; TST signed for them on waybill 766-4148797.
TST-Overland moved the shipment through Sarnia, ON for delivery to TST-Porter Burnaby, BC.
TST-Porter in Burnaby verified receipt of two skids.
CFL was called to pick up 2 skids from TST-Porter in Burnaby on waybill 354-982526 per the attached copy.
CFL delivered the shipment of one pallet only to Williams Lake November 2.
Trace started with CFL November 9."

Devices are five Sealed Source Fixed Gauges activity of 100 mCi each Serial Numbers (5943CN, 5950CN, 6157CN, 6160CN, 6165CN).

Ohio report number: OH070006

* * * UPDATE AT 0845 ON 11/23/07 FROM B. BEAUDIN TO P. SNYDER * * *

Mr. Beaudin from the Canadian Nuclear Safety Commission called with information that the missing sources were found intact in Burnaby, B.C. The sources were never lost. They were misplaced and located in a warehouse at a different location than expected.

Notified Ohio (S. James), R3DO (M. Ring) and FSME EO (A. Mohseni). Notified via email R4DO (J. Clark), FSME NMED PM (Burgess), R3 SLO (via M. Ring), R4 SLO (McLean, Erickson), OIP (Baker, Dembeck) and ILTAB.

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.

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The State provided the following information via email:

"The Licensee reported this event in June and filed a report in a letter that was misfiled causing a delay in this notification.

"A gauge user in the employ of the licensee was using a Troxler model 3440 moisture density gauge serial number 31185 at a temporary jobsite in Issaquah. The employee placed the gauge in an area staked to exclude construction traffic. The employee left the gauge unattended to retrieve an item from the user's vehicle. While away from the gauge, a pickup backed towards the gauge in the staked area. Workers in the area attempted to get the driver's attention and stop the pickup but failed. The pickup struck the gauge and caught the handle under the hitch of the truck, breaking the stationary rod and bending the source rod. The source appeared to have remained in its shielded position. The gauge was dislodged from the pickup by moving the pickup forward. The gauge user cleared personnel within a 50 foot area around the gauge and contacted the RSO. The RSO went to the jobsite with a survey meter and performed surveys. Survey readings indicated the source had remained in its shielded position. The damaged gauge rods were secured with cloth tape. The gauge was place in the transport box and returned to its licensed storage location. A leak test was taken at that time and the results returned were normal.

"The gauge user's employment with the licensee was terminated for violating the licensee's Operating and Emergency Procedures by leaving the gauge unattended at the jobsite.

"The licensee currently reports they are still in possession of the damaged gauge and presently storing it in that condition. The licensee is working with a carrier to get it shipped properly to Troxler in North Carolina.

"Notification Reporting Criteria: WAC 246-221-250 Notification of Incidents.

"Isotope and Activity involved: 8 mCi of Cesium 137, and 40 mCi of Americium 241 Beryllium.

"Overexposures? (number of workers/members of the public; dose estimate; body part receiving dose; consequence): None known.

"Lost, Stolen or Damaged? (mfg., model, serial number): Damaged Troxler, model 3440, Serial Number 31185.

"Disposition/recovery: The damaged gauge was placed in the manufactures transport, stored at the licensed storage location and held for pick up and repair or disposal by the manufacturer.

"Leak test? Results of the leak test taken at time of the incident were normal."

TECHNICAL SPECIFICATION REQUIRED PLANT SHUTDOWN DUE TO INOPERABLE LOAD SEQUENCER

"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.

"On Friday, November 23, 2007, at 22:26 Mountain Standard Time (MST) Palo Verde Nuclear Station Unit 1 initiated a normal reactor shutdown to comply with Condition H of Technical Specifications (TS) Limiting Condition for Operation (LCO) 3.8.1.

"TS LCO 3.8.1 requires that automatic load sequencers for train A and B be operable in Modes 1, 2, 3 and 4. The shutdown is necessary due to an inoperable automatic load sequencer for train A in Unit 1. The train A automatic load sequencer was declared inoperable on November 22, 2007, at 19:30 MST and was not restored to operable status within the TS required 24 hour completion time of Condition F of TS 3.8.1. TS 3.8.1 Condition H requires the plant to be placed in MODE 3 within 6 hours and MODE 5 within 36 hours if the required actions and associated completion time of TS Condition F are not met. Efforts are in progress to correct the condition.

"The event did not result in the release of radioactivity to the environment and did not adversely affect the safe operation of the plant or health and safety of the public."

The licensee is taking measures to evaluating the extent of this condition from the remaining automatic load sequencers for Units 1, 2 and 3. The inoperability was discovered due to an invalid actuation of the A train load sequencer that resulted in a pond spray pump initiation.

The licensee notified the NRC Resident Inspector.
