The temperature dependence of G-values for aqueous solutions irradiated with a 23 MeV 2H+ beam

Computer simulation of water radiolysis in the primary heat transport system of a nuclear power reactor requires, among other things, the g-values of eaq-, OH, H, H2, and H2O2 formed in the fast neutron radiolysis of water at 280o-325oC. These g-values cannot be easily measured directly. However, they can be estimated from a knowledge of the g-values for radiations which have linear energy transfer values characteristic of that found in a reactor. We report on an experimental technique for irradiating water samples at elevated temperatures with ion beams and present some g-values for irradiations with a 23 MeV deuteron beam. (author)
