... Abstract Once fuel failures occur in a reactor core, the fission gas will release from the UO2 pellet to the fuel-to-sheath gap and eventually enter the primary coolant through the cladding wall breach. The crew of nuclear power plant regularly sample the primary coolant and characterize...

... activity levels in a pressurized water reactor. It is necessary to determine the status of fuel failure to avoid its degradation in the operation. This paper introduces the mechanism of the generation and release of fission products in fuel rods and the primary loops in a pressurized water reactor...
