Matrix graphite powder for high-temperature/ultrahigh-temperature gas cooled reactor fuel element, preparation method of matrix graphite powder, matrix graphite and fuel element
The invention provides matrix graphite powder for a high-temperature/ultrahigh-temperature gas cooled reactor fuel element, a preparation method of the matrix graphite powder, matrix graphite and the fuel element, and belongs to the technical field of high-temperature/ultrahigh-temperature gas cooled reactors. The nuclear-grade graphene powder is added into the raw materials of the matrix graphite powder, so that the graphene modified matrix graphite can be subsequently prepared, and the matrix graphite has high thermal conductivity, low thermal expansion coefficient, thermal expansion anisotropy and low wear rate, and can ensure safe operation of a fuel element under the high-temperature/ultrahigh-temperature condition of a reactor.
本发明提供了一种高温/超高温气冷堆燃料元件用基体石墨粉及其制备方法和基体石墨、燃料元件，属于高温/超高温气冷堆技术领域。本发明的基体石墨粉的原材料中添加了所述核级石墨烯粉，所以后续可以制备得到石墨烯改性的基体石墨，所述基体石墨具有高热导率、低热膨胀系数及热膨胀各向异性、低磨损率，能保障燃料元件在反应堆高温/超高温条件下安全运行。
