ITEM RELIED ON FOR SAFETY (IROFS) INOPERABLE
The following information was provided by the licensee via phone and email:
"At approximately 2345 MDT, on 4/1/2024, it was observed that the physical boundary of IROFS10 had been opened while this boundary was being relied upon to perform its safety function. This initial report is being made as a 1-hour notification under Appendix A to 10CFR70 (a)(4). The boundary (an isolation valve) was partially opened inadvertently by contact with adjacent equipment while performing operation of 1003 liquid sampling autoclave. The partially opened valve has been shut, restoring the IROFS10 boundary, and the autoclave has been placed in cooling mode. Out of conservatism, until an extent of condition can be performed, the 1004 autoclave which has a similar design has been taken out of service and placed in cooling mode as well.
"There has been no indication of leakage from any operating liquid sampling autoclave to the environment. The system and plant are in a stable condition."
The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
The isolation valve was open less than 30 seconds and there was no exposures to personnel. The licensee will notify the NRC Region.

AGREEMENT STATE REPORT - RECEIVED DOSE LESS THAN PRESCRIBED
The following information was received from the Georgia Department of Natural Resources (GADNR), Georgia Radioactive Materials Program, via email:
"On Monday April 1, 2024, GADNR received notification from our licensee, [license number] GA 796-1, of a brachytherapy seed migration post implant of Iodine-125 seeds. The reporting official is the hospital's Manager of Radiation Physics [MRP]. [The MRP] was contacted via cell phone today, April 2, 2024, for further information. [They] stated that each seed was approximately 0.635 mCi, totaling 18.62 mCi. The patient was seen some time last week and their computed tomography (CT) results were analyzed yesterday during their post implant CT exam. The prescription was 145 Gy to the prostate using 18.62 mCi of I-125. The D90 to the target was 46.2 percent instead of the expected 80-120 percent on the post implant dosimetry. [The MRP] will be sending a full report of this incident within the next 15 days. [GANDR] will follow up with more information at a later date."
* * * RETRACTION ON 4/9/24 AT 0807 EDT FROM ANASTASIA BENNETT TO BILL GOTT * * *
The following information was received from the Georgia Department of Natural Resources (GANDR), Georgia Radioactive Materials Program, via email:
"GADNR is requesting closure of the incident case as it does not meet the reporting criteria outlined in 10 CFR 35.3045(a)(2)(i)(2) for permanent implant brachytherapy. Specifically, the incident does not involve the administration of byproduct material or radiation from byproduct material resulting in a total source strength administered differing by 20 percent or more from that documented in the post-implantation portion of the written directive, excluding instances where sources migrate outside the treatment site."

PART 21 - INTERIM REPORT FOR UNVERIFIED CRITICAL CHARACTERISTICS OF DARMATT KM-1 FLAT BOARD
The following is a summary of the information provided by Transco Products Inc. via email:
10 CFR Part 21 Initial Notification: TPI-LTR-2024-01-01-0
On November 16, 2023, during an audit review, it was determined that the dedication plan was inadequate. The dedication plan lists chemical properties as one of the critical characteristics with the acceptance criteria. The extent of condition is limited to Darmatt KM-1 flat board supplied to Energy Northwest (Columbia Generating Station). The issue has been entered into Transco Products Inc.'s corrective action program. Testing to verify the chemical properties of the supplied flat board is in process. Energy Northwest was the only impacted licensee and they have been notified.
