Graphite in nuclear reactor
WebBecause fast reactors rely on a different type of fission reaction than LWRs do, they require different reflector materials. Graphite and beryllium act as neutron moderators, reducing neutron energy that must be kept high. Fast reactors also have smaller cores with higher power densities, placing greater demands on the reflector material. WebDec 1, 2024 · Drawing of CP-1, the world's first nuclear reactor. Argonne National Laboratory. 4. The reactor was built with graphite blocks, some of which contained small disks of uranium. 5. Scientists monitored the reaction on instruments named after Winnie the Pooh characters—Piglet, Tigger and Pooh. 6.
