Simulation of the transport of fission products in the fuel-to-sheath gap of defective CANDU fuel rods
Creators
Description
The differential equations describing the transport of volatile fission products within the fuel to sheath gap in a CANDU fuel element have been established, and solved both analytically and numerically, for the two different cases: normal operation and reactor accident conditions. For both cases, the results obtained were in very good agreement, and well within the uncertainty of some of the parameters, such as the diffusion coefficients. The computer code PRODFISS has been written in a general way so that the model can be applied to other volatile fission products and to LWR fuel elements. 11 refs., 1 tab., 6 figs
