AGREEMENT STATE REPORT - STUCK SOURCE
The following information was received from the state of Ohio via email:
"On Monday 2/20/2023, radiographers from the licensee's Akron, Ohio office experienced a source that would not retract. There were two radiographers working on the job site when they realized that their source was not locking into the safe position. They contacted management at 1013 [CST] and were instructed to move their boundaries out and use physical barriers to prevent unauthorized access. When the licensee's source retrieval team arrived on site, they discussed the situation with the crew and began to form a plan for locating the source.
"The retrieval team located the source in the collimator and then developed a plan for a way to shield and retract the source. The retrieval team made 16 moves to shield the source before attempting retrieval. The source was locked in the safe, shielded position inside the camera at 1510.
"The source retrieval team found that the drive cable connector had broken just above the crimp causing the source and pigtail to become disconnected from the cable. The licensee reports that the connector lot number is FW-21, and it was put into service on 12/18/2022."

"At 1618 EST on February 20, 2023, North Anna Power Station notified the Virginia Department of Environmental Quality (DEQ) that water discharged into Lake Anna following hydrostatic testing of tanks associated with a new on-site sewage treatment plant had exceeded the project's general permit (VAG83) pH value.
"Hydrostatic test water discharge activities to Lake Anna began on February 20, 2023 at 0900 EST. A pH sample was collected at 0955 EST on February 20, 2023 and determined to have a pH of 9.1 which exceeded the maximum permit pH of 9.0. Discharge ceased after the reading was collected. Approximately 354 gallons were discharged to Lake Anna. A follow-up ambient pH sample result of 7.8 was collected on February 20, 2023 at 1401 EST from Lake Anna in the vicinity of the discharge pipe. No evidence of dead fish, foam, or other negative environmental impacts were observed.
"This event is reportable in accordance with 10 CFR 50.72(b)(2)(xi) for 'Any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an on-site fatality or inadvertent release of radioactively contaminated materials.'"
