Abstract
Autooxidation of Np(IV) in 4 and 6 M HNO3, induced by self-alpha-radia tion, has been experimentally studied and simulated. Neptunium(IV) is oxidized mainly via reaction with Np(VI). Rate constants for the react ions Np(IV) + Np(VI) and Np(V) + Np(V) were determined by comparing ex perimental and calculated current and equilibrium concentrations of Np (IV) and Np(V).
