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.

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。该项目旨在为第四代SCWR化学项目开发实验和分子建模工具，主要关注超临界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（如管道、涡轮叶片）上的腐蚀产物沉积。该项目的主要技术目标是调查氢和联氨水化学物质在加拿大- scwr运行条件下抑制水放射性溶解影响的可行性。这项工作预计将大大节省未来的运营成本，并将更好地保护环境。
