Water Chemistry, pH Control and Particle Formation Processes in a CANDU-SCWR

超临界水冷核反应堆（SCWR）是满足未来能源市场需求的创新候选者。该项目旨在为Gen IV SCWR化学计划开发实验和分子建模工具，主要关注超临界含水流体及其与核反应堆材料的相互作用。我们的主要研究目标是确定水化学规范，以最大限度地降低腐蚀速率，并最大限度地减少SCWR堆芯内和堆芯外组件上的腐蚀产物沉积（例如，管道、涡轮机叶片）。该项目的主要技术目标是研究氢和肼水化学在超临界水反应堆运行条件下抑制水辐解效应的可行性。这项工作预计将大大节省未来的运营成本，并将导致更好的环境保护。

The supercritical water-cooled nuclear reactor (SCWR) is an innovative candidate to meet the future needs of the energy market. This project aims to develop experimental and molecular modeling tools for the Gen IV SCWR chemistry program, with the main focus on supercritical aqueous fluids and their interactions with nuclear reactor materials. Our key research goal is to identify water chemistry specifications that will minimize corrosion rates and minimize corrosion product deposition on in-core and out-of-core components of the SCWR (e.g., piping, turbine blades). The main technical objective for this project is to investigate feasibility of the hydrogen and hydrazine water chemistries for the suppression of the effects of water radiolysis at the operating conditions of the Canadian-SCWR. This work is expected to offer significant savings in future operating costs and will result in a better environmental protection.
