"On 10/12/2022, the Radiation Safety Officer [RSO] at Siemens Medical Solutions USA, Inc. (IL-01130-02), notified the Agency regarding a leaking Co-57 sealed source received on 10/12/2022 from the manufacturer, Eckert & Ziegler. The 15 mCi point source was opened and handled in a restricted area behind a small L-block. Upon removal from the packaging (noted as intact), the source was placed in a tungsten holder and was promptly leak tested by the RSO. Leak test results indicated contamination levels of 23,000 dpm [disintegrations per minute] on the source capsule and 140,000 dpm on the inside of the baggie in which the source was shipped in. Subsequent area and personal surveys were performed with no contamination noted. The source, baggie and a few tools used in the initial handling of the source were doubled bagged and remain secured at Siemens pending return to the manufacturer. The leaking source was reported to IEMA within 5 days as required in accordance with 32 Illinois Administrative Code 340.1260 and was then reported to the NRC as required. The investigation is ongoing."

EN Revision Text: SECONDARY CONTAINMENT INOPERABLE DURING SURVEILLANCE

The following information was provided by the licensee via email:

"At 0427 CDT on October 20, 2022, Grand Gulf Nuclear Station (GGNS) was in Mode 1 at 100 percent power when a failure of a draw down surveillance resulted in the loss of secondary containment. During the performance of the surveillance GGNS was unable to maintain secondary containment pressure, as required by Technical Specification Surveillance Requirement 3.6.4.1.4, greater than or equal to 0.266 inches of water vacuum for 1 hour at a flow rate of less than or equal to 4000cfm.

"The test was secured. Secondary containment was declared inoperable and Technical Specification 3.6.4.1 A.1 was entered at 0427 CDT. Secondary containment was restored to operable status at 0520 CDT by restoring the configuration to a previously known operable condition.

"This event is being reported as an event or condition that could have prevented the fulfillment of a safety function.

"The NRC Resident Inspector was notified."
