Abstract
The course and causes of the emergency that took place in 1993 on the sorption unit for production of ultrapure (PU)-P-238 at the Radioisoto pe Plant, Mayak Production Association, are discussed. The thermal cal culations and thermogravimetric studies of anion exchanger samples (no nirradiated, irradiated, and saturated with plutonium) showed that the emergency was due to draining of the liquid from the column and progr essing thermochemical degradation of VP-1Ap anion exchanger.
