EN Revision Text: AGREEMENT STATE REPORT - IMPROPER SOURCE SHIPMENT

The following was received from the Louisiana Department of Environmental Quality (DEQ) via email:

"Louisiana DEQ was notified by Source Production & Equipment (SPEC) Radiation Safety Officer, via the DEQ Radiation Hotline at approximately 1045 CDT on November 5, 2021, concerning an industrial radiography camera shipment from Nigeria. According to the RSO, Dynaquest Energy Limited in Nigeria wanted to exchange three Industrial Radiography Ir-192 sources. When the package was received, two of the drums had the Industrial Radiography cameras (SPEC 150) and the other drum did not have a camera just the unshielded source. The unshielded source was in the type B container without a camera. The source is an Ir-192 with 0.06987 Ci. The reading on the side of the drum was 300 mR/hr and the reading from the top of the drum with the lid off was 40 - 50 mR/hr. SPEC retrieved the source and put it in a shield. The individual that was handling the package and retrieval received 5 mR exposure. The two cameras were a SPEC 150 (s/n 2619) with Ir-192 source s/n AF2815 and SPEC 150 (s/n 2618) with Ir-192 source s/n AF2814 and were locked. SPEC 150 (s/n 2618) did not have a locking cap on it even though the camera was locked. SPEC stated that they will hold on to the devices and terminate their relationship with Dynaquest Energy Limited."

EN Revision Text: TECHNICAL SPECIFICATION VIOLATION

"This is a required notification per University Of Missouri Research Reactor (MURR) Technical Specification (TS) 6.6.c(1) to report to the NRC Operations Center that an Abnormal Occurrence, as defined by MURR TS 1.1, had occurred. MURR was not in compliance with one Limiting Conditions of Operations (LCO). TS 3.2.f states, 'The reactor shall not be operated unless the following rod run-in functions are operable.' Specifically, the rod run-in function that occurs when water level in the anti-siphon system is greater than or equal to 6 inches above the anti-siphon isolation valves was not operable as required by TS 3.2.f.6.

"On 11/8/21 while the reactor was shut down for maintenance and conducting surveillance testing on the anti-siphon system high level rod run-in instrument channel, the surveillance testing provided measurement that indicated the rod run-in actuation may not have occurred until water level was slightly greater than 6 inches above the anti-siphon isolation valves. Previously on 4/22/2021, the anti-siphon system high level rod run-in instrument channel activated the rod run-in well below the top of the anti-siphon isolation valves.

"Troubleshooting revealed the stainless-steel cable that connects the channel's level controller to its suspended displacer (float) had developed loops in it, effectively shortening the cable. The cable with loops made the rod run-in actuation occur at a higher water level than when the cable has no loops in it. The loops in the cable were removed. The instrument channel was retested and documented to be back in compliance with TS 3.2.f.6.

"On 11/9/21, MURR engineers analyzed the data collected from the 11/8/21 measurement and concluded that prior to removing the loops from the level controller cable, the rod run-in was actuating at a level of approximately 7.3 inches above the anti-siphon isolation valves, which is greater than the maximum of 6 inches above the valves required by TS 3.2.f.6.

"In accordance with TS 6.6.c(4) before it was known if MURR deviated from TS 3.2.f.6, the Acting Reactor Facility Director was briefed and gave permission to restart the reactor prior to the reactor returning to operation later on 11/8/21. Currently, MURR is operating at 10 MW. A detailed event report will follow within 14 days as required by MURR TS 6.6.c(3)."

OFFSITE NOTIFICATION DUE TO PCB OIL SPILL

"At 1515 EST on 11/10/21, approximately 89 gallons of PCB oil is unaccounted for from the Substation 'N' Transformer, located in the Owner Controlled Area. Transformer nameplate oil capacity is 569 gallons. Prior to removal of the original Substation 'N' Transformer, approximately 475 gallons of 10-CA-OIL (PCB Oil) was evacuated and stored by HEPACO (a licensee vendor). Approximately 5 gallons of oil is inaccessible to evacuate and remains in the original transformer. Below the transformer was evidence of oil leakage to the ground. The leakage appears to have been occurring over time, not as a result of a catastrophic failure. This condition is reportable to the Virginia Department of Environmental Quality (VA DEQ). The VA DEQ was notified of this condition at 1815 on 11/10/21. Cleanup activities are on-going.

"This event is reportable in accordance with 10CFR50.72(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.'"

The licensee will be notifying the Louisa County administrator and has notified the NRC Resident Inspector.
