Graphite as moderator in nuclear reactor
WebOct 7, 2024 · X-10 was fueled with natural uranium, its neutrons moderated with graphite, and its heat removed by air blowers. It generated up to 4 megawatts of thermal power. It operated from 1943 to 1963. The first post-war research reactor in the US, the Brookhaven National Laboratory Graphite Research Reactor, was modelled after X-10. http://large.stanford.edu/courses/2024/ph241/barry2/
