Radiochemistry Aims and scope

Abstract

Gas liberation in systems ion exchanger-nitric acid solution in open and closed vessels under the action of elevated temperature and ionizing radiation is studied. Preliminary data on the detonation properties of VP-1AP anion-exchange resin are given. No considerable gas liberation is observed in the system in the presence of the liquid phase, but explosive thermochemical degradation of the sorbent can occur as a result of drying of the sorbent phase. Elevated temperature and ionizing radiation increase the probability of this process.
