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.

水的辐射分解会产生氢，氧气和过氧化氢，这可能对系统成分有害。 这些物种的放射性产生可以通过适当的化学剂量，少量溶解的氢或氧气清除化学物质（如氢氮）来缓解。 Candu反应堆端屏蔽冷却系统中碳钢成分的腐蚀会消耗氧气，这也可以使系统处于净放射性抑制状态。该项目旨在研究通过腐蚀与放射性消耗过程之间的氧气消耗之间的关系。
