A STATE LICENSEE REPORTED ONE OF THEIR TROXLER MOISTURE DENSITY GAUGES HAD BEEN STOLEN

A Troxler moisture density gauge was stolen from the company truck while parked at the private residence of a Wingerter Laboratory employee. The gauge was checked out from the company at 0630 and taken to his residence to pick up job related paperwork. While at the job site the RSO was notified at 0830 that the gauge was missing. The driver said he made no stops while driving from his residence to job site. The Troxler gauge (model 3440, serial #19973) contained 8 mCi (milliCuries) of Cs-137; 40 mCi of AM-241/Be. Wingerter is offering a $1000 reward for the return of the gauge in local newspaper.

Florida incident #FL05-120

This is less than the quantity of a IAEA Category 3 source. 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.

For some of these sources, such as moisture density gauges or thickness gauges that are IAEA 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.

Event Text

REACTOR TRIP DUE TO MAIN GENERATOR HYDROGEN LEAK

"The Palisades reactor was manually tripped from approximately 100% power at 1025 hours EDT due to a hydrogen leak from main generator. At 1027 hours, an automatic actuation of the auxiliary feedwater system occurred, as designed, to maintain steam generator levels. The atmospheric steam dump valves opened and reseated per design on reactor trip. Reactor decay heat is being removed via steaming through the turbine bypass valve to the main condenser. The source of the hydrogen leak was determined earlier to be a cracked weld that could not be repaired on line. The main generator must be purged in order to repair the weld.

"This is reportable under 10 CFR 50.72(b)(2)(iv)(B) and (b)(3)(iv)(A)."

All control rods fully inserted. There are no known Steam Generator tube leaks. The licensee notified the NRC Resident Inspector.
