Evaluation of FP behavior models in SAs, 4; Evaluation of a chemical reaction model in SA codes

Karasawa, Hidetoshi; Miwa, Shuhei; Kino, Chiaki*

As CsI is the main fission product, the transport behavior was examined using the TeRRa apparatus and found to produce gaseous iodine. To analyze CsI behavior, a chemical reaction model was made and evaluated. The chemical model was introduced to the SAMPSON code and analyzed the TeRRa experiment. We could explain the experimental results such as the formation of gaseous iodine, formation of aerosol and deposition of aerosol due to thermophoresis.
