AGREEMENT STATE REPORT - PACKAGE RECEIVED BY LICENSEE EXCEEDS SURFACE RADIATION DOSE LIMITS

The following information was received from the Commonwealth of Massachusetts via email:

"A shipment of radioactive material in the form of 5 packages, each containing 555 GBq of Americium/Beryllium, was delivered to QSA Global, Inc. at 0830 [EDT] on October 2, 2020, each of which exceeded regulatory package dose rate limits. All 5 packages exceeded the surface dose rate limit of 200 mrem/hour, the highest of which was 295 mrem/hour and the lowest 220 mrem/hour. Each package was labeled as Yellow III; TI 7. The transport index was also exceeded with a range of 13 mrem/hr at 1 meter for the lowest and 15 mrem/hr at 1 meter for the highest.

"It was reported that the final delivery carrier, [a common carrier], was notified of the event at 1430 [EDT] on October 2, 2020. The shipper, Weatherford International, LLC, at 7504 Benbrook Parkway, Benbrook, Texas, 76126, was also notified.

"The cause of the event is under investigation by the licensee. Further information from the Massachusetts Radiation Control Program will be forthcoming."

The Commonwealth will be notifying NMED.

AUTOMATIC REACTOR TRIP

"At 0026 [EDT] on October 12, 2020, D.C. Cook Unit 2 tripped automatically on low-low level of #24 steam generator which occurred after a lowering of main condenser vacuum.

"The reason for the lowering main condenser vacuum and the reason for the low steam generator #24 level is under investigation.

"This notification is being made in accordance with 10 CFR 50.72(b)(2)(iv)(B), Reactor Protection System (RPS) actuation as a four (4) hour report. Notification is also being made as an eight (8) hour report under 10 CFR 50.72(b)(3)(iv)(A) due to actuation of the Auxiliary Feedwater System (AFW).

"The D.C. Cook Resident NRC Inspector has been notified.

"Unit 2 is being supplied by offsite power. All control rods fully inserted. Auxiliary Feedwater Pumps started as required and are operating properly. Decay heat is being removed via steam generator power operated relief valves (PORVs) due to condenser steam dump unavailability from low main condenser vacuum. All four Reactor Coolant Pumps remain running. Preliminary evaluation indicates all plant systems functioned normally following the reactor trip. D.C. Cook Unit 2 remains stable in Mode 3. No radioactive release is in progress as a result of this event."
