摘要： Example embodiments are directed to providing a thin, adherent coating on the surfaces of nuclear reactor components, which are known to cause increased corrosion on adjacent zirconium alloy structures, and methods of reducing the increased corrosion. Example embodiments include coatings being structurally bonded to components such that the difference in the corrosion potential between a coated component and a zirconium alloy component is less than that between a component without the coating and the zirconium alloy component.

摘要： Microstructured nuclear fuel adapted for nuclear power system use includes fissile material structures of micrometer-scale dimension dispersed in a matrix material. In one method of production, fissile material particles are processed in a chemical vapor deposition (CVD) fluidized-bed reactor including a gas inlet for providing controlled gas flow into a particle coating chamber, a lower bed hot zone region to contain powder, and an upper bed region to enable powder expansion. At least one pneumatic or electric vibrator is operationally coupled to the particle coating chamber for causing vibration of the particle coater to promote uniform powder coating within the particle coater during fuel processing. An exhaust associated with the particle coating chamber and can provide a port for placement and removal of particles and powder. During use of the fuel in a nuclear power reactor, fission products escape from the fissile material structures and come to rest in the matrix material. After a period of use in a nuclear power reactor and subsequent cooling, separation of the fissile material from the matrix containing the embedded fission products will provide an efficient partitioning of the bulk of the fissile material from the fission products. The fissile material can be reused by incorporating it into new microstructured fuel. The fission products and matrix material can be incorporated into a waste form for disposal or processed to separate valuable components from the fission products mixture.
摘要翻译：适用于核电系统使用的微结构核燃料包括分散在基体材料中的微米级尺寸的裂变材料结构。在一种生产方法中，在化学气相沉积（CVD）流化床反应器中处理裂变材料颗粒，该反应器包括用于提供受控气体流入颗粒涂层室的气体入口，含有粉末的下床热区域，上床区域使粉末膨胀。至少一个气动或电动振动器可操作地耦合到颗粒涂层室，以引起颗粒涂层机的振动，以在燃料加工期间促进粒子涂布机内均匀的粉末涂覆。与颗粒涂层室相关的废气可以提供用于放置和去除颗粒和粉末的端口。在核能反应堆中使用燃料时，裂变产物从易裂变材料结构中逃逸，并停留在基体材料中。在核动力反应堆使用一段时间后，随后的冷却，将裂变材料从含有嵌入裂变产物的基体中分离出来，将能够从裂变产物中大量分解裂变材料。裂变材料可以通过将其并入新的微结构燃料中来重新使用。裂变产物和基质材料可以并入废物形式，用于处理或加工以将有价值的成分与裂变产物混合物分离。
