Heat Threshold During Self-Burial Process of Radioactive Waste

he concept of heat threshold is brought forward for the melting process of radioactive source with constant heat rate. The heat threshold and related approaching time for the nuclear waste self-burial melting process of typical nuclear reactor are analyzed and calculated, which are compared with the results in related published literature. The corresponding melting depth is also calculated. Some errors in the published literature are pointed out, and some significant conclusions are drawn.
