Framatome has completed the second 18-month cycle of its GAIA Protect Enhanced Accident Tolerant Fuel (EATF) technology at Vogtle’s Unit 2 in Waynesboro, Ga. Inspections afterward revealed that the full-length chromium-coated fuel rods maintained their original characteristics, while the chromia-enhanced pellets operated as designed during 36 months of reactor operation.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

The nuclear industry’s first 100 percent accident tolerant fuel assembly is in operation at Exelon Generation’s Calvert Cliffs plant, the Department of Energy announced yesterday. The advanced fuel will operate in the reactor for the next four to six years and will be routinely inspected to monitor its performance, the DOE said.
Located in Lusby, Md., Calvert Cliffs houses two pressurized water reactors. Unit 1 is rated at 907 Mwe, and Unit 2 at 881 Mwe.

Several lead test rods of Westinghouse’s EnCore accident tolerant fuel recently arrived at Oak Ridge National Laboratory for post-irradiation examination over the next year in support of the Nuclear Regulatory Commission’s licensing process. The rods were installed in 2019 in Exelon’s Byron-2, a 1,158-MWe pressurized water reactor, and were removed in fall 2020 and prepared for shipment to ORNL.

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.
