AGREEMENT STATE REPORT - SHUTTER MALFUNCTION

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

"On April 28, 2022, the licensee notified the Agency that the shutter handle on one of its Ohmart Vega model SH-F2 gauges, containing a 200 milliCurie cesium-137 source, had malfunctioned. A service company was preparing the gauge for removal and had opened and closed the shutter. The shutter closed completely (verified by survey), but they could not lock the shutter handle. A repair kit will be ordered and upon receipt the service company will make the repair and complete the removal. The gauge is in an area of the plant that is no longer operational in a location that is inaccessible without scaffolding. The scaffolding being used at the time of this event will be removed until time for repair.

"There were no exposures as a result of this event. More information will be provided as it is obtained in accordance with SA-300."

AGREEMENT STATE REPORT - MEDICAL EVENT DUE TO DISCREPENCY WITH WRITTEN DIRECTIVE

The following summary was received from the Wisconsin Department of Public Health (the Department) via email:

On April 28, 2022, during an inspection, the Department became aware of a medical event involving Y-90 TheraSphere which occurred on June 21, 2021. A patient's procedure planned for two vials and an activity of 2.81 GBq, which were administered. The written directive erroneously only accounted for one vial and a prescribed activity of 1.94 GBq; therefore, the administered activity was 138.4 percent of the activity specified on the written directive. The administered activity was within 2 percent of the planned activity.

VALID ACTUATION OF UNIT 2 AND UNIT 3 EMERGENCY DIESEL GENERATORS AND UNIT 3 AUXILIARY FEEDWATER PUMP

The following information was provided by the licensee via email:

"At 1955 on May 4, 2022, a start-up transformer de-energized, resulting in a loss of power to the Unit 2 Train A 4.16 kV Class 1E Bus and the Unit 3 Train B 4.16 kV Class 1E Bus. The Unit 2 Train A Emergency Diesel Generator (EDG) and Unit 3 Train B EDG automatically started and energized their respective 4.16 kV Class 1E Buses.

"As a result of the Loss of Power on the Unit 3 Train B 4.16 kV Class 1E Bus, the B Auxiliary Feedwater Pump automatically started, as expected. The B Auxiliary Feedwater Pump was not needed for steam generator level control and no auxiliary feedwater valves repositioned. The B Auxiliary Feedwater Pump did not supply feedwater to the steam generators.

"This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of emergency AC electrical power systems and an auxiliary feedwater system."
