Keywords:Cs deposition distribution, Phebus-FPT1 test, SAMPSON code

Cs deposition distribution in the primary circuit was evaluated by Phebus FPT1 test analyses using the SAMSON code. This time, deposition distribution of Cs was compared with that of Mo. Effects of chemical forms of Cs and Mo were examined to deposition and transport of Cs.
