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 has the property of absorbing neutrons.

Graphite is used in some nuclear reactor types as a moderator to moderate (or slow down) neutron energy.

it was manufactured by man

Water and graphite are often thought of as moderators as regards nuclear reactors.

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.

Chernobyl, however it was not a nuclear explosion. It was a steam explosion that blew the roof off the reactor building and ejected roughly a third of the reactor contents, followed by a graphite fire ignited when air hit the hot graphite moderator of the damaged reactor.

US, manufactured by Martin Company.

United States nuclear power plants do not use graphite for operation and thus the answer is "none". Graphite is used in some reactor designs as a "moderator", which is the reactor feature that slows down neutrons so that the chain reaction will continue. US nuclear plants are "light water reactors" which means that they use regular water as the moderator. Canadian plants, for example, are "heavy water" plants which use duterium as a moderator. Chernobyl, the Ukranian plant that exploded in the 1980's, used graphite as a moderator.

An atomic pile is an early form of nuclear reactor fuelled by uranium and moderated with graphite.

A pencil's 'lead' is manufactured from a type of carbon called 'graphite' which is a conductor.

Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.

The nuclear reactions are: 23892U + n-------23992U-------23993Np + e

No, control rods in nuclear reactors are not made of graphite. The control rods have to be able to gather up the neutrons to shut the reactor down, so boron is often selected. Graphite is used in some reactors as a moderator, and a moderator slows down neutrons. The slower neutrons have a greater ability to undergo neutron capture to continue the chain.

Yes, there are a number of plants, mainly of the gas cooled graphite moderated type.

It's purpose is to slow down fast neutrons that maybe present in the reactor.

no graphite rod not radioactive but these r absorb radioemission rays that's why people think so because in the nuclear plant graphite rod use as a controling nuclear reaction by absirb the nuclear emission rays .A2. The graphite is used as a Moderator - a material that slows the neutrons down sufficiently that they have a greater chance of collision and thus releasing some of their energy. Which we use as thermal energy.Otherwise, the neutrons would have only a small chance of interacting - they are travelling very fast, and the dimensions of a nuclear pile is only a metre or so in dimension. Having interacted to give up some of their energy, the neutrons then just lose the remainder of their energy in the shielding.
