Adding a new simulation in the Gas-cooled Microreactor (GCMR) assembly of a postulated reactivity insertion accident (RIA). Similarly, to the previous simulation of flow blockage, a 3-D dynamic Multiphysics simulation was completed by coupling Griffin, BISON, SAM, where the Griffin transport solver DFEM-SN with CMFD acceleration was used.
