The graphite used in graphite moderated nuclear reactors is produced in the same type of electrical furnace as is used to produce ordinary graphite, except there must be no boron in any part of the furnace.
Graphite, Concrete and Lead.
it was manufactured by man
If you are looking to fit a new graphite shaft to your club, I would say it doesn't matter which graphite shaft is the best but it is which one is best for you. Either a Grafalloy or Mitsubishi shaft, but they can be quite expensive.
Graphite is not usually extracted from rocks. Graphite is manufactured in an electric furnace heating an ordinary source of carbon (e.g. coke, charcoal) under high pressure without any oxygen.
District 13 actually has two occupations. The Capitol told everyone that their industry was graphite, and that their citizens were graphite miners. The Capitol did not mention, however, that District 13 also supplied them with nuclear weapons. So District 13's occupations are graphite mining and nuclear weaponry.
When and what explosion? One of the nuclear test shots. If so which?Remember Chernobyl was not a nuclear explosion, it was a steam explosion and graphite fire.
Its industries were mining graphite and nuclear science/technology.

It can be light water, heavy water, or graphite
Nowhere as far as I can find. Perhaps you are thinking of the 1986 Chernobyl steam explosion and graphite fire. This was in the USSR and although the graphite fire melted much of the core, it was not a meltdown in the usual sense associated with nuclear reactors.
Graphite is a pure form of coal or carbon. It is a good conductor of heat and electrcity. It is used as a neutron moderator in nuclear reactors of type Gas Cooled reactors.
