Chemical reactions of $α$–radiolysis, hydrolysis and complex formation as well as oxidizing–reducing processes in alkali solutions of ions UO$^{2+}_2$, PuO$^{2+}_2$, AmO$^{2+}_2$ have been analyzed. It has been established that polyuranites and superuranites, phosphate, carbonate and nitrate precipitates of uraninite and plutoninite may arise in aqueous solutions, which are characteristic of the object ‟Shelter". Hydrodynamic–fluctua\-ti\-on theory for calculation of bimolecular reactions is presented. Calculation of mutual diffusion and viscosity transfer coefficients for ions UO$^{2+}_2$, PuO$^{2+}_2$ and atomic hydrohen in aqueous solutions is carried out.
