Report of 4th research meeting on basic process of fuel cycle for nuclear fusion reactors, Yayoi Research Group

In this meeting, the problem of plasma exhaust in actual machines, the problem of the basic process for recovering tritium from breeder materials, the DT experiment at TFTR, the basic research on superpermeation and so on were taken up. At the meeting, lectures were given on the present state of the research on LHD divertor exhaust method, particle balance in TEXTOR, ALT-2 pump limiter experiment, the recovery of tritium from liquid breeder materials, the surface process of tritium release from Li ceramics, DT experiment at TFTR and the behavior of hydrogen in niobium and the possibility of superpermeation. In this report, the summaries of the lectures are collected, and also the program of the meeting and the list of attendants are shown. (K.I.)
