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.

水的辐解产生氢、氧和过氧化氢，这可能对系统组件有害。 这些物质的辐射分解产生可以通过适当的化学剂量与少量溶解的氢或氧清除化学品，如肼，减轻。 CANDU反应堆端盖冷却系统中碳钢部件的腐蚀消耗氧气，这也可以使系统保持在净辐射抑制状态。本项目旨在研究腐蚀耗氧与辐射耗氧过程之间的关系。
