I have put a link to the Wikipedia page, "List of nuclear reactors," below. It seems to be pretty good, and includes some reactors that are not in nuclear plants, such as research reactors.
They provide energy.
In nuclear reactors, to produce electricity
NO
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.
Plutonium is very important for nuclear weapons and for nuclear fuels used in nuclear reactors. But plutonium is also toxic and radioactive. See the link below.
This is taken from Wikipedia, about India and nuclear power Uranium used for the weapons program has been separate from the power program, using Uranium from indigenous reserves. This domestic reserve of 80,000 to 112,000 tons of uranium (approx 1% of global uranium reserves) is large enough to supply all of India's commercial and military reactors as well as supply all the needs of India's nuclear weapons arsenal. Currently, India's nuclear power reactors consume, at most, 478 metric tonnes of uranium per year. Even if India were to quadruple its nuclear power output (and reactor base) to 20GWe by 2020, nuclear power generation would only consume 2000 metric tonnes of uranium per annum. Based on India's known commercially viable reserves of 80,000 to 112,000 tons of uranium, this represents a 40 to 50 years uranium supply for India's nuclear power reactors (note with reprocessing and breeder reactor technology, this supply could be stretched out many times over). Furthermore, the uranium requirements of India's Nuclear Arsenal are only a fifteenth (1/15) of that required for power generation (approx. 32 tonnes), meaning that India's domestic fissile material supply is more than enough to meet all needs for it strategic nuclear arsenal. Therefore, India has sufficient uranium resources to meet its strategic and power requirements for the foreseeable future.
No. Nuclear reactors would be a good project for science, but don't use much physics. Try nuclear weapons. A gun assembly or implosion type fission bomb both use a lot of physics.
The US has 104 operating reactors and none of them have exploded. It's a matter of good design and operating methods. Nuclear explosions though are not possible in a commercial nuclear reactor, because the nuclear fuel is not sufficiently enriched to make a weapon, whatever happens in the reactor.
Uranium is used as nuclear fuel for nuclear power reactors. Nuclear power plants don't contribute to global warming, greenhouse effect, carbon dioxide releasing. Uranium is now the most important alternative to fossil fuels.
Carbon is a very good moderator, for use in gascooled reactors, the others not.
I'm not sure if that is true. The US has 104 operating power reactors. I think if you add up those in Western Europe, in France, UK, Germany, Spain, Belgium for example, it will still be fewer. A good source of information is www.world-nuclear.org
