AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE
The licensee completed testing at jobsite and thought he had stowed his moisture density gauge (Troxler model 3340, SN 25752, 8 - 10 mCi Cs-137/ 40 mCi Am-241/Be). He left the jobsite in Shingle Springs, CA, and while in-transit to Elk Grove, CA (via highway 50) the technician heard a thud from outside of the vehicle but did not think anything of it. When the technician arrived at his residence he noticed the truck's tailgate was down and realized the gauge was missing. He backtracked to the jobsite and was unable to locate the gauge on the highway or at the jobsite. The technician notified the RSO, the Elk Grove Police Department and the California Highway Patrol. The State will provide more information as it becomes available.
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 INVOLVING A STOLEN TROXLER MOISTURE DENSITY GAUGE
The following information was received via email:
"The Minnesota Department of Health (MDH) has been notified that on September 13, 2007 at approximately 2:00 PM, a moisture-density gauge containing sealed sources of radioactive material was stolen from a pick-up truck owned by Asset Management. The truck was parked at a residence in Forest Lake, Minnesota, and the gauge was believed to have been stolen sometime during the previous night.
"The MDH, which regulates the use of these types of radioactive materials in Wisconsin, is working with the Forest Lake Police Department and officials of Asset Management to recover the stolen gauge.
"The moisture density gauge is used to measure the moisture content and density of soils and building materials. The gauge is a yellow box measuring approximately 30 inches in length, 14 inches in width and 17 inches in height (see attached picture). The gauge and the case weigh a total of 90 pounds. The gauge itself weighs 29 lbs. The case and the gauge are clearly marked as containing radioactive materials. . ."
The gauge is a Troxler Model 3430 (S/N 33277) containing two (2) sources; 9 milliCuries Cs-137 and 44 milliCuries Am-241:Be. The State of Minnesota issued a press release with contact information for the return of the gauge.
MN Report No.: MN070006.
* * * UPDATE FROM MDH (JOHNS) TO CROUCH AT 1358 EST ON 12/17/07 * * *
The Troxler moisture density gauge was recovered at 0600 CST this morning. An unknown person placed the gauge outside the Forest Lake, MN Police Department. The gauge appeared intact and no detectable leakage existed. The gauge was returned to the licensee.
Notified R3DO (Duncan), FSME (Morell), and ILTAB via email.

POTENTIAL REACTOR PRESSURE BOUNDARY LEAKAGE
"During an investigation in response to a low megger reading, a small amount of water was discovered in the environmental qualification boundary of the 22B RCS Thot thermowell (TE-3-422B2). Analysis of the water on 9/13/07 at 2304 showed Cesium 137 and 134, and Magnesium 54 indicating that the source of water intrusion into the thermowell was likely reactor coolant system (RCS) fluid. We are continuing the investigation for potential causes of water intrusion other than the Reactor Coolant System. This report is being made based on the previous indication of RCS leakage into 23A, RCS Tcold thermowell (TE-3-420) [see EN #43627 from 09/10/07] and similar discovery in our preliminary investigation.
"PTN Unit 3 Technical Specifications (TS) Limiting Condition for Operation (LCO) 3.4.6.2.a permits no reactor coolant pressure boundary leakage in Modes 1-4. This report to the NRC is pursuant to the requirements of 10 CFR 50.72 (b)(3)(ii)(A) as a degraded condition."
Turkey Point Unit 3 is presently defueled.
The licensee will notify the NRC Resident Inspector.

NOTICE OF UNUSUAL EVENT FOR A HYDRAZINE SPILL IN THE TURBINE BUILDING
"A Notification of an Unusual Event was declared at 06:01 EDT due to a chemical leak in the Turbine Building truck dock area near a roll-up door. The leak was discovered at 05:40 EDT coming from a line connecting two vertically stacked Hydrazine Metal chemical storage totes located inside a ventilated enclosure. The Hazmat Response Incident Team was formed to address the spill. Approximately 10 gallons is inside the enclosure berm. A small amount of liquid has leaked outside the enclosure berm but has been contained. Containment activities are in progress. Leak rate appears to be significantly less. Additional plant staff has been called in to support and are arriving on site at the time of this notification. The area has been roped off and plant announcements to warn personnel of this hazard have been made. (EAL-11.4, Plant Conditions Warrant Increased Awareness by Plant Staff)"
The licensee notified the NRC Resident Inspector, state and local government agencies.
* * * UPDATE AT 0742 ON 9/13/07 FROM CHLADIL TO ROTTON * * *
The licensee terminated the Notice of Unusual Event. The termination criteria was that the spill was stopped and the licensee has established limited personnel access restrictions to the turbine building truck bay and the service building elevator. The licensee is continuing to clean the area.
The licensee notified the NRC Resident Inspector and will be notifying state and local government agencies.
Notified R4DO (Shannon), NRR (Ross-Lee), IRD (Blount), DHS (Haselton) and FEMA (Laforty).
