Heat Transfer During Evaporation of Cesium From Graphite Surface in an Argon Environment

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 r...
