The thermal decomposition of RbMnO/sub 4/, preirradiated in the spent- fuel facility at Harwell and in a hollow uranium slug in BEPO, was investigated in the temperature range 195 to 245 deg C. The results for gamma -irradiated RbMnO/sub 4/ are similar to those for irradiated AgMnO/sub 4/ and KMnO/sub 4/, and the mechanism proposed for the latter is again suggested. The activation energy for the migration of point defects over the induction period is 1.59 ev. The p-t plots for pile-irradiated HbMnO/sub 4/ are complex ard are explained in terms of a mechanism involving the formation of thermal and/or displacement spikes. (auth)
