Heat Transfer During Evaporation of Cesium From Graphite Surface in an Argon Environment
The article focuses on discussion of problem of graphite radioactive waste formation and accumulation. It is shown that irradiated nuclear graphite being inalienable part of uranium graphite reactor may contain fission and activation products. Much attention is given to the process of formation of radioactive cesium on the graphite element surface. It is described a process of plasma decontamination of irradiated graphite in inert argon atmosphere. Quasi one mathematical model is offered, it describes heat transfer process in graphite cesium argon system. Article shows results of calculation of temperature field inside the unit cell. Authors determined the factors which influence on temperature change.
