EN Revision Text: AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE

The following was received from the Texas Department of State Health Services (the Agency) via email:

"On October 12, 2020, the licensee notified the Agency that on October 10, 2020, one of its technicians completed a job at a temporary job site in Dallas, Texas, and drove to another temporary job site in Venus, Texas. Upon arriving, the technician found he did not have the Humboldt 5001 EZ moisture/density gauge in his truck. The gauge contained an 8 milliCurie cesium-137 and a 40 milliCurie americium-241/beryllium source. The technician believed he left the gauge at the Dallas site so he drove back to that site. The gauge was not there. The technician called his supervisor but never made contact. The technician called the company office and left a voicemail about the incident which was retrieved this morning. The licensee is notifying local law enforcement, contacting area pawn shops, and conducting its investigation. More information will be provided as it is obtained in accordance with SA-300."

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.

CONCURRENT REPORT FOR SHIPMENT OF UNDECLARED HAZARDOUS WASTE

The following information was provided by the licensee via email:

"Framatome is making a concurrent report [following a report made to the Department of Transportation] in concurrence with 10 CFR 70 Appendix A(c), Concurrent Reports for Offsite Notification or News Release.

"An undeclared hazardous material was discovered following a completed waste shipment. The undeclared material was 18.3 grams of U-238 (depleted uranium).

"A hazardous waste shipment left the Framatome site on August 5, 2022, for Clean Earth Specialty Waste Solutions in Tacoma Washington.

"On September 22, 2022 at about 1130 [PDT], a Framatome Waste Engineer informed Framatome EHS&L (Environmental Health Safety and Licensing) management that this shipment included waste that had not passed the free release criteria for radioactive waste.

"The shipment included seven containers that went to Clean Earth Specialty Waste Solutions in Tacoma, Washington on the August 5th, 2022 shipment. To date, five of the seven waste containers have been returned to Framatome and have been confirmed that no radioactive material was present. The first of the two remaining waste packages is listed in sections 14, 26 and 27 above. [14-Proper Shipping Name of Hazardous Material: UN3262 Waste Corrosive solid, basic, inorganic, not otherwise specified (n.o.s.), 8pgII; 26-Identification Markings: UN 1H2/X65/S/22/USA/M4990 1610 2.2mm; 27-Package Capacity:15 Gallons, Amount in Package: 21 pounds, Number in Shipment: 2, Number Failed: None]

"The second [not yet returned] package included material not regulated by Department of Transportation, (WA state dangerous waste only, Toxic). Both packages were of the same UN specification markings."

SECONDARY CONTAINMENT INOPERABLE DURING SURVEILLANCE

The following information was provided by the licensee via email:

"At 1228 CDT on October 27, 2022, Grand Gulf Nuclear Station (GGNS) was in Mode 1 at 88 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 4000 cfm.

"The test was secured. Secondary containment was declared inoperable and Technical Specification 3.6.4.1 A.1 was entered at 1228 CDT. Secondary containment was restored to operable status at 1240 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."
