AGREEMENT STATE REPORT - STOLEN NUCLEAR DENSITY GAUGE

The following report was received from the State of California via email:

"The RSO [Radiation Safety Officer] of Geolabs reported to the RHB [Radiation Health Branch] that his gauge technician had reported a CPN MC-3 (serial number M37067701) was stolen. The CPN gauge contains 10 milliCuries of Cs-137 and 50 milliCuries of Americium-241, and was inside its Type A transportation container. The technician was transporting the CPN gauge to a temporary job site. The RSO will be contacting the Ventura County Sheriff's Dept. to report the theft and take a statement from the technician. This is an ongoing investigation."

California 5010 number: 043019

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.

EN Revision Text: MANUAL REACTOR TRIP DUE TO MISALIGNED CONTROL ROD

"At 1643 [CDT], with Unit 2 in Mode 2 during low power physics testing, the reactor was manually tripped per procedure due to a misaligned control rod. The trip was not complex, with all systems responding normally post-trip.

"Operations responded and stabilized the plant. Decay heat is being removed by discharging steam to the atmosphere using the atmospheric relief valves. Unit 1 is not affected.

"Due to the Reactor Protection System actuation, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B).

"There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."

* * * UPDATE ON 05/08/2019 AT 1212 EDT FROM MIKE CONNER TO JEFFREY WHITED * * *

"This Event Notification is being updated to clarify that the reactor was not critical when this event occurred. Therefore, the reporting requirement is changed from 10 CFR 50.72(b)(2)(iv)(B) to 10 CFR 50.72 (b)(3)(iv)(A).

"The reactor was tripped during low power physics testing. The misaligned rod was encountered during rod group insertion and the affected bank had been inserted to the extent that the reactor was subcritical when the operators tripped the reactor.

"The licensee notified the NRC Resident Inspector."
