Loss of coolant accident analysis under restriction of reverse flow

open access: yesNuclear Engineering and Technology, 2019
This paper analyzes a new method for reducing boiling water reactor fuel temperature during a Loss of Coolant Accident (LOCA). The method uses a device called Reverse Flow Restriction Device (RFRD) at the inlet of fuel bundles in the core to prevent ...
