In order to acquire the data on fission product chemical behavior during transport in a reactor for the improvement of source term evaluation method, we performed the chemical reaction tests of cesium (Cs) and iodine (I) deposits and boron oxide (B $_{2}$ O $_{3}$ ) vapor/aerosol using the apparatus which can simulate temperature conditions of reactor coolant system under a sever accident. The volatile I compounds were formed by the reaction of B $_{2}$ O $_{3}$ vapor/aerosol and deposit, and significant amount of I was revaporized from the deposit.
