Nuclear fuel high-temperature compact composite material and preparation method thereof
The invention relates to a nuclear fuel material, and provides a high-temperature compact composite nuclear fuel material and a production method thereof. The high-temperature compact composite nuclear fuel material comprises a ceramic irradiation inert matrix, and nuclear fuel particles are distributed in the ceramic irradiation inert matrix. The base body is made of a silicon carbide powder material. The nuclear fuel particles are particles of an oxygen-free nuclear fuel. A method of producing a high temperature dense composite nuclear fuel material includes preparing a mixture of nuclear fuel pellets and an inert irradiated ceramic matrix powder, forming the mixture by pressing and sintering. The molded mixture is sintered by hot pressing. The group of inventions makes it possible to obtain the high-temperature compact composite nuclear fuel material, and the mass loss of the material does not exceed 2% after the material is annealed for 10 hours under the vacuum condition of 0.63 (melting point).
本组发明涉及一种核燃料材料，并提供了一种高温致密复合核燃料材料及其生产方法。高温致密复合核燃料材料包含一个陶瓷辐照惰性基体，核燃料颗粒分布在其中。基体由碳化硅粉末材料制成。核燃料粒子是无氧核燃料的粒子。一种生产高温致密复合核燃料材料的方法包括制备核燃料颗粒和惰性辐照陶瓷基体粉末的混合物，通过压制和烧结成型混合物。模制混合物通过热压烧结。这组发明使得获得高温致密复合核燃料材料成为可能，这种材料在0.63（熔点）的真空条件下退火10小时后，其质量损失不超过2%。
