摘要

为了在研究堆中使用低浓缩燃料，提高燃料元件的燃耗，正在开发以铀钼高温合金为基础的金属陶瓷合金。合金结构以γ相为基础，其中也包含陶瓷（金属间）相。这些相具有最高的铀密度，与铝相容，高抗辐射性和低钼含量，沿着晶界沉淀，这使得通过粉碎获得燃料颗粒成为可能。这符合现有的技术。使用这种燃料将有可能在不增加费用的情况下制造和供应铀密度和性能提高的低浓缩燃料（燃料元件）给研究反应堆。

Application of metal-ceramic uranium-molybdenum fuel in an aluminum matrix for research reactors

In order to use reduced enrichment fuel and increase the burnup of fuel elements in research reactors, metal-ceramic alloys based on uranium-molybdenum superalloys are being developed. The alloy structure is based on a γ-phase, which also contains ceramic (intermetallic) phases. Having the highest density of uranium, compatibility with aluminum, high radiation resistance, and low molybdenum content, these phases precipitate along grain boundaries, which allows fuel particles to be obtained by crushing. This fits into the existing technology. The use of such fuel will make it possible to manufacture and supply reduced enrichment fuel (fuel elements) with increased uranium density and performance to research reactors without increasing costs.
