AGREEMENT STATE REPORT - STUCK OPEN SHUTTER

The following is a summary provided by the Illinois Emergency Management Agency (the Agency) via email:

On June 8, 2023 at 0920 CDT, the licensee (Roquette America Inc.) in Gurnee, IL, advised the Agency of a stuck open shutter (Ohmart fixed gage, 15 mCi, Cs-137). The reportable equipment failure was discovered during a routine shutter check. The Radiation Safety Officer confirmed that the gauge will remain in its mounted condition attached to a small sectional tank and that operators were immediately advised of the inoperable shutter. The manufacturer was notified and confirmation for a site visit to repair the shutter is pending. No personnel exposures occurred as a result. The incident was reported to the Agency within 24 hours as required under 32 Ill. Adm. Code 340.1220(c)(2). Agency staff will perform a reactionary inspection to ensure adequate control of the gauge and area until the shutter is repaired.

THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

OFFSITE NOTIFICATION - OIL RELEASE

The following information was provided by the licensee via email:

"On 6/13/23 at approximately 1030 PDT, testing was being conducted on a lubricating oil system which interfaces with a cooling water system that has a pathway to the Columbia River. Due to an equipment failure, an indeterminate amount of oil leaked into the cooling water system, with a maximum potential loss of 300 gallons of oil. At 1230 PDT, an oil sheen was identified on the water basin which is the suction and discharge for this cooling system. The discharge pathway to the river was isolated at 1235 PDT. Investigation at the Columbia River showed no signs of oil sheen. This is being reported to offsite agencies under the Columbia Generating Station NPDES [National Pollutant Discharge Elimination System] Permit section S3.E.b. l and RCW [Revised Code of Washington] 90.56.280 due to the discharge of oil which has the potential to cause a sheen on the surface of the river.

"This condition is being reported pursuant to 10CFR50.72(b)(2)(xi) for news release or notification of other government agencies related to health and safety of the public or protection of the environment. Notifications to off-site agencies were performed at 1842 PDT on 6/13/2023.

"United States Coast Guard National Response Center Incident Report# 1369989.

"Washington State Emergency Management Division Report# 23-2245.

"Discharge pathway will remain secured until on-site cooling water system has been remediated.

"The NRC resident has been informed."
