The thermal properties of materials used in nuclear reactors, either as constituents of fuel or as components in the reactor or containment systems, are not always well characterized at higher temperatures or in aqueous environments. As nuclear power plants push the design envelopes by taking the reactors to higher power outputs, the fuel is running hotter. This has implications for safety analysis when the materials are taken outside their designed function. This research program will: 1) Investigate metallic systems that form during nuclear fuel burn-up to determine their thermal properties; 2) Develop the experimental methodologies to improve the accuracy of thermodynamic data for use in simulation models; 3) Develop novel materials for use in advanced nuclear fuel cycles; 4) Construct test equipment to study high temperature (above 100 °C) aqueous systems and measure thermodynamic properties of metal-water systems; 5) Develop fundamental understanding of materials properties for use in hydrogen generation technologies; 6) Develop Highly Qualified Personnel with a knowledge of thermochemistry as it relates to the nuclear and energy sectors. The research program will involve the following four projects: i) Examine metallic systems in nuclear fuel; ii) Develop a sensor for measuring the oxygen pressure at high temperatures; iii) Measure thermochemical properties of materials in connection with hydrogen generation from the copper-chlorine cycle. iv) Experimental Determination of High Temperature Pourbaix Diagrams

核反应堆中使用的材料，无论是作为燃料的成分还是作为反应堆或安全壳系统中的组件，其热性能在较高温度下或在水性环境中并不总是很好地表征。 随着核电站通过将反应堆提高到更高的功率输出来推动设计信封，燃料正在变热。 当材料超出其设计功能时，这对安全分析有影响。 这项研究计划将： 1)研究核燃料燃耗过程中形成的金属系统，以确定其热性能; 2)制定实验方法，以提高模拟模型中使用的热力学数据的准确性; 3)开发用于先进核燃料循环的新型材料; 4)建造试验设备，研究高温（100 °C以上）水系统，并测量金属-水系统的热力学性质; 5)发展对用于制氢技术的材料特性的基本理解; 6)培养具有热化学知识的高素质人才，因为它涉及到核和能源部门。 该研究计划将涉及以下四个项目： ㈠检查核燃料中的金属系统; ㈡开发一种用于测量高温下氧气压力的传感器; ㈢测量与铜-氯循环产生氢有关的材料的热化学性质。 iv）高温Pourbaix图的实验测定
