The "Generation IV" CANDU Supercritical Water-Cooled reactor ("SCWR") is a conceptual design for a would produce super-critical water at temperatures as high as 625°C to generate electricity, hydrogen and district heating. The use of super-critical water to carry heat from the reactor core to the turbine will generate much more extreme water chemistry conditions than those found in the current CANDU-PHW design, which operates from 250 to 320°C. The long term viability of the Gen IV CANDU-SCWR concept depends on the ability of designers to predict and control water chemistry, in order to minimize radionuclide transport and subtle corrosion effects. The region of most importance is the range from 275 to 450 °C and 25 MPa, the so-called "pseudo transition zone" which includes sub-critical and supercritical aqueous solutions at liquid-like densities. This is a frontier region of hydrothermal chemistry, both because the SCWR would require a unique

“第四代”CANDU超临界水冷反应堆（“SCWR”）是一种概念设计，将产生温度高达625 °C的超临界水，用于发电、氢气和区域供暖。使用超临界水将热量从反应堆堆芯输送到涡轮机，将产生比当前CANDU-PHW设计（运行温度为250至320 °C）中的水化学条件极端得多的水化学条件。第四代CANDU-SCWR概念的长期可行性取决于设计人员预测和控制水化学的能力，以最大限度地减少放射性核素迁移和微妙的腐蚀影响。最重要的区域是从275到450 °C和25 MPa的范围，即所谓的“伪过渡区”，其中包括液体密度的亚临界和超临界水溶液。这是热液化学的前沿领域，因为SCWR需要独特的
