A graphite-moderated reactor is a nuclear reactor that uses carbon as a neutron moderator, which allows natural uranium to be used as nuclear fuel. The first artificial nuclear reactor, the Chicago Pile-1 , used nuclear graphite as a moderator.
The X-10 Graphite Reactor is a decommissioned nuclear reactor at Oak Ridge National Laboratory in Oak Ridge, Tennessee. Formerly known as the Clinton Pile and X-10 Pile , it was the world's second artificial nuclear reactor (after Enrico Fermi 's Chicago Pile-1 ) and the first intended for continuous operation.

The RBMK (Russian: Реактор большой мощности канальный, РБМК; reaktor bolshoy moshchnosti kanalnyy, "high-power channel-type reactor") is a class of graphite-moderated nuclear power reactor designed and built by the Soviet Union. It is somewhat like a boiling water reactor as water boils in the pressure tubes.
[18] [20] The site was chosen for the X-10 Graphite Reactor, used to produce plutonium from natural uranium. Enrico Fermi and his colleagues developed the world's second self-sustaining nuclear reactor after Fermi's previous experiment, the Chicago Pile-1. The X-10 was the first reactor designed for continuous operation. [21]
Nuclear graphite is any grade of graphite, usually synthetic graphite, manufactured for use as a moderator or reflector within a nuclear reactor.Graphite is an important material for the construction of both historical and modern nuclear reactors because of its extreme purity and ability to withstand extremely high temperatures.
Research reactor DIORIT, PSI (10 March 2014) Operation of Diorit ceased in 1977. First plans for dismantling were made in the early 80s, while the actual decision was made in 1994. During decommissioning of the reactor the following amounts of radioactive waste accrued: 250 t steel, 120 t concrete, 5.4 t aluminium and alloys, as well as 45 t ...
The graphite used to construct Fort St. Vrain's core was higher grade and less porous, and thus did not present as much surface area for these reactions to occur. [3] Although system safety was not compromised, frequent operation problems were experienced throughout the reactor systems due to water and corrosion.
