Progress in vapor adsorption test using molecular sieve for helium coolant purification system

An ambient molecular sieve bed (AMSB) plays a role in capturing the tritiated water, Q2O, in the coolant purification system (CPS) which is designed to capture the tritium in helium cooling system (HCS) of the nuclear fusion reactor [1]. To confirm the function of AMSB, RAVAD (Research Apparatus for Vapor Adsorption and Desorption) was established by KAERI and KFE [2]. Main purpose of this study is to compare absorption characteristics of AMSBs according to various operation conditions.
