We describe results that advance the understanding of radiation effects in HLW stored at DOE sites. The scientific issues on which we focus include: a) reactions of primary radicals (e-, OH, and H) of water radiolysis with NO3-/NO2-, b) redox chemistry of NOx radicals and ions, c) degradation mechanisms and kinetics of organic components of HLW, and d) interfacial radiolysis effects in aqueous suspensions and at crystalline NaNO3 interfaces. Understanding these effects and the chemical reacations they induce have contributed to resolving safety issues and setting waste management guidelines at Hanford.
