PWR Response to an Inadvertent Boron-Dilution Event

Conference ·
OSTI ID:6025512
Response of a pressurized water reactor (PWR) to an inadvertent boron-dilution event during refueling was studied experimentally in the Loss-of-Fluid Test (LOFT) facility and in a plexiglass model of the LOFT reactor vessel. These experiments showed that good mixing of the diluent and fluid volumes occurred in the direct-flow-path volumes which are used in simulating residual heat removal (RHR) in a PWR. In addition, other fluid volumes, not in the RHR path, also mixed, delaying the time to criticality beyond that expected based on RHR volumes only.
