An experimental study of the molten glass/water thermal interaction. Topical report. [LMFBR]
Molten glass interacts explosively with water under certain contact mode conditions. The contact mode found explosive is as follows: molten glass enters the water bath in the film boiling regime (as predicted by Henry's correlation) and soon after entry, the vapor film is perturbed sufficiently by an external pressure pulse. The ensuing reaction proceeds basically along the same lines as energetic tin/water interactions observed by several investigators. In the absence of this pressure pulse, the event is non-energetic. The reported findings are for a combination in which the hot material has a very low thermal diffusivity and the calculated interface temperature is significantly (175C) below its melting temperature. This is similar to the characteristics of the UO2/sodium combination. The observed explosive glass/water interactions show growth times of the order of a few milliseconds. The particulate size distribution from the present tests was coarser than the particulate size distribution from some in-pile and out-of-pile UO2/sodium interaction tests.
