Transport of fission product vapours in the Falcon thermal gradient tube
Fission product transport in the primary circuit of a light water reactor depends crucially on the physical state of transported species. This report analyses the behaviour of vapours in four integral Falcon experiments via the predictions of VICTORIA92/ESTER. Only the thermal gradient part of the Falcon circuit was analysed. The main differences in the experimental boundary conditions were the presence/absence of boric acid, carrier gas oxygen potential, and fission product molar fraction. It is concluded that VICTORIA predicts aerosol deposition profiles well, but more experiments are needed to validate the full thermodynamic equilibrium approach used in VICTORIA.
