一、简介大约十至十五年前,在德国反应堆石墨研制中,等静压石墨承担了重要角色。除了挤压和模压外,利用了等静压工艺生产各向同性石墨,此项工艺甚至使用了非各向同性焦为原料,特别是在天然沥青焦(Gilsonite)愈来愈难获得的时候。在七十年代,德国高温反应堆的原理得到了发展,这种反应堆的概念是假定当大约400℃时,在侧面反射层的一些地区,快中子负载可以达到4×10~(26)个中子/m~3(等价 I. Introduction About 10 to 15 years ago, isostatic graphite took an important role in the development of German reactor graphite. In addition to extrusion and molding, isotropic processes are used to produce isotropic graphite, which even uses non-isotropic coke as a starting material, especially as it becomes harder to obtain natural pitch coats. In the seventies, the German high-temperature reactor principle was developed. The concept of this reactor is that it assumes that in some areas of side reflectors, the fast neutron load can reach 4 × 10 ~ (26) when about 400 ℃ Sub / m ~ 3 (equivalent
