The moderator slows (moderates their speed/energy) neutrons from the 1 MeV that they have when emitted in fission to less than 1 eV.
The reason a moderator is needed in most reactors is that their fuel is still mostly Uranium-238, which easily captures 1 MeV neutrons and potentially stopping the neutron chain reaction but is unable to capture neutrons less than 1 eV which still easily fission the small percentage of Uranium-235 in the fuel.

How much graphite is used in a nuclear power plant per year?
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.
Most of the nuclear power plants currently operating in the US are classified as.....?
Most nuclear power plants currently operating in the US are classified as pressurized water reactors (PWRs). These reactors use water as both a coolant and moderator to generate electricity through nuclear fission. PWRs are the most common type of nuclear reactor in use worldwide.
What continents have the most nuclear power plants?
Europe and North America have the most nuclear power plants. France has the highest concentration of nuclear power plants in Europe, while the United States has the highest number of nuclear power plants in North America.
What do nuclear power plants have to do with nuclear energy?
Nuclear power plants use nuclear energy as their source of power. They harness the energy released from nuclear reactions (such as fission) to generate electricity. The heat produced by these reactions is used to create steam, which drives turbines to generate electricity.
Are there nuclear power plants in North Carolina?
Yes, North Carolina has nuclear power plants. There are currently three operating nuclear power plants in the state: Brunswick Nuclear Generating Station, Harris Nuclear Plant, and Shearon Harris Nuclear Power Plant.
Which is used as a moderator in nuclear reactor?
Most current power plants use water, but heavy water, graphite, hydrocarbons, etc. could be used instead.
