Graphite moderated nuclear reactors
WebGraphite has historically been used as a moderator material in nuclear reactor designs dating back to the first man-made nuclear reactor to achieve criticality (Chicago Pile 1) in 1942. Additionally, graphite is a candidate material for use in the future envisioned next-generation nuclear reactors (Gen IV); specifically, the molten-salt-cooled ... WebAt this time there was an abundance of experience in graphite manufacture in the US, so Fermi used graphite to produce the first graphite moderator reactor (known as …
