Title: The influence of chemistry on severe accident phenomena in integral tests

Abstract

The influence of chemistry on in-vessel severe accident phenomena in integral effects in-pile tests is reviewed. In-vessel severe accident chemistry involves high temperature interactions between the materials used in the tests; namely, fuel rods, control materials, spacer grids, and steam. The influence of chemistry on the release and transport of fission products has been found to be strongly dependent on core melt progression phenomena such as fuel liquefaction, control rod failure, and molten debris relocation. The extent of fuel irradiation, the presence of control materials and spacer grids, and the amount of steam available are important factors in determining the chemistry of the tests. Much has been learned about the influence of chemistry under PWR accident conditions, but additional information is needed on chemical interactions between fission product vapors and aerosols and on the influence of chemistry under BWR accident conditions 37 refs., 2 tabs.
