Abstract

Safe operation of a supercritical water cooled reactor requires knowledge of the reaction kinetics of transient species formed by the radiolysis of water in the temperature range 300-650°C. By using a light isotope of the H·atom, it is possible to study its chemistry in water over this range of temperatures.  Arguably, the most important reaction to study is that of the H·atom with the bulk solvent.  This reaction could provide an in situ source of H2 gas, which is added to CANDU reactors to suppress oxidative corrosion. The work described here concerns studies of the reaction of muonium with H2O and D2O at temperatures up to 450°C.
