DESIGN STUDY OF SWEEP GAS SYSTEM FOR FUSION BLANKET DEVELOPMENT IN THE JMTR

A breeder blanket, whose purposes are to breed tritium and to produce thermal energy, is indispensable for a fusion reactor. In addition to demonstrating the physics of burning D-T plasmas, an experimental reac tor such as the ITER will also conduct a verification test of a blanke t design. An in-pile functional test has been considered to obtain abo ve engineering data since 1992 in the JMTR project. The sweep gas syst em which is a system to measure and recover the uitium released from a blanket mock-up has been designed. From the results of the design, th e sweep gas system will be sufficient for the inpile functional test i n the JMTR.
