Nitrogen compounds’ formation in aqueous solutions under high ionizing radiation: An overview

Authors: G.R. Dey Generation of NO-3 and NO-2 in aqueous phase within high ionizing radiation zone is normal phenomena. Their formation mechanisms, and controls still remain a challenge with reference to creation of corrosive environment. Nitrogen in such system relates mainly to air ingress, and from added nitrogen compounds, which are used to control pH and dissolved oxygen. Under radiation…

Multi-Scale Modeling of the Gamma Radiolysis of Nitrate Solutions

Authors: G.P. Home, T.A. Donoclift, H.E. Sims, R.M. Orr, S.M. Pimblott A multiscale modeling approach has been developed for the extended time scale long- term radiolysis of aqueous systems. The approach uses a combination of stochastic track structure and track chemistry as well as deterministic homogeneous chemistry techniques and involves four key stages: radiation track structure simulation, the subsequent physicochemical…
