Effect of Cladding Failure on FCCI Layer and Fission Product Behavior

Yuanzineng kexue jishu
Nuclear fuel rods are the first barrier preventing the release of fission products to the environment in the operation of nuclear power plants. Zirconium alloys are favored for their advantages, such as a low neutron absorption cross-section, excellent ...

Criticality safety of fuel assemblies with missing fuel rods

Annals of Nuclear Energy
International audience ; The present work is concerned with the problem of determining the reactivity of an assembly from which an unknown number of fuel pins are removed at random locations. Because it is usually designed to be under-moderated, the reactivity of an incomplete assembly will pass by an optimum when the number and position of the missing
