Study on the α -ray radiolysis product of hydroxysemicarbazide

Hydroxysemicarbazide (HSC) as a novel salt-free organic reductant has the ability to accomplish the reduction of Pu(IV) fast in the nuclear fuel reprocessing. The radiolysis products of reductant varies along the absorbed does of aqueous solution suffered as a result of increasing fuel burn-up, which potentially imperil the separation process. Accordingly, it is necessary to determine the speciation and amount of radiolysis products of HSC in the media of nitric acid solution to lay the foundation for its later application. The experiment of HSC irradiated by α -ray in nitric acid aqueous solution was carried out and the yields speciation was analyzed in this paper. In addition, the G(HSC) and radiolysis products influenced by variation of radiation ( α -ray, β -ray, γ -ray) was researched parallelly in our work.
