AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The following is a summary of information received from the Colorado Department of Public Health and Environment by e-mail:

The licensee reported a damaged Troxler 3430 portable moisture density gauge (SN:24886) containing Am-241/Be (SN:4721079) and Cs-137 (SN:757025) sources. The gauge fell out of the back of a truck onto an interstate highway while in transit. Pieces of the gauge are on the interstate as a result of vehicles running over the gauge and the licensee is attempting to retrieve them. The licensee intends to contact the police to help cordon off the affected area to support retrieval of the remaining pieces and conduct surveys. A search is ongoing and some of the pieces of the gauge have not been accounted for.

CO Incident Number: CO220013

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 GAUGE

The following is a summary of information received from the New Jersey Department Environmental Protection (NJDEP) by e-mail:

On 4/27/2022, North State Materials notified NJDEP that an asphalt roller bumped a density gauge (Troxler model 4640-B, serial #77923 with a Cs-137 source up to 9 milliCuries) at a jobsite in Harmony, New Jersey. The incident was caused by heavy equipment operator error. The operator intended to move the roller backwards, but instead moved forward. The damage was limited to the faceplate and the plastic on one corner of the gauge. The licensee surveyed the gauge to confirm the source was properly shielded prior to transporting it to the licensee's storage location in Philipsburg, NJ. A sealed source leak test is pending.

EN Revision Text: AGREEMENT STATE REPORT - TELETHERAPY DEVICE FAILED IN SHIELDED POSITION

The following information was received from the Texas Department of State Health Services (the Agency) via e-mail:

"On April 27, 2022, the Agency received a notification from the licensee that the drive mechanism on their Theratronics T708C teletherapy device failed in the shielded position. The device contains 5,042 Curies of Co-60. The licensee stated that while starting a procedure at around 0915 hours CDT on April 27, 2022, the technician found that the source would not move out from the shield. There were no exposures as a result of this event. The licensee contacted a service company and scheduled a repair. An investigation is ongoing."

MANUAL REACTOR TRIP AND AUTOMATIC ACTUATION OF AUXILIARY FEEDWATER SYSTEM

The following information was provided by the licensee via email:

"At 1541 EDT on May 3, 2022, with Unit 1 in Mode 1 at 100 power, the reactor was manually tripped due to the loss of one of the main feed pumps. The trip was not complex, with all systems responding normally post-trip. No equipment was inoperable prior to the event that contributed to the event or adversely impacted plant response to the scram.

"Operations responded and stabilized the plant. Decay heat is being removed by Auxiliary Feedwater through the steam dumps to the condenser. Unit 2 is not affected.

"An automatic actuation of the Auxiliary Feedwater System (AFW) also occurred. The AFW auto-start is an expected response from the reactor trip.

"Due to the Reactor Protection System actuation while critical, this event is being reported as a four-hour, nonemergency notification per 10 CFR 50.72(b)(2)(iv)(B). This event is also being reported as an eight-hour, nonemergency notification per 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the Auxiliary Feedwater System.

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

"The NRC Resident Inspector has been notified."
