Mitigating Hydrogen Production in the End Shield Cooling System of CANDU Reactors

Radiolysis of water produces hydrogen, oxygen and hydrogen peroxide, which can be deleterious to system components. The radiolytic production of these species can be mitigated through appropriate chemical dosing with small amounts of dissolved hydrogen or oxygen-scavenging chemicals such as hydrazine. Corrosion of carbon steel components in the End Shield Cooling system of a CANDU reactor consumes oxygen, which can also keep the system in a state of net radiolytic suppression. This project aims to study the relation between oxygen consumption through corrosion versus the radiolytic consumption processes
