[1K06] Evaluation of Fission Product Released during the NPP Sevier Accident
(18)Evaluation of Cs deposition behavior by Phebus FPT1 test analysis
Keywords:SAMPSON code, Phebus FPT1 test, Cs chemical forms, deposition mechanism
Cs deposition mechanism was evaluated by analesis of the Phebus FPT1 test using the SAMPSON code. Chemical forms of Cs species are Cs2MoO4 and CsOH/CsI, which have been considered to be main Cs chemical forms. Main deposition mechanisms were condensation and thermophoresis.
