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.
A large PWR or BWR will contain about 75 tonnes of uranium fuel, and will change roughly 25 tonnes every refuelling outage which is about every two years.
Depends on the design.
It takes about 8-10 mn $ to setup a nuclear power plant. but the resources used in it are inexpensive common in the earth's crust
We don't yet know how to use fusion in a power plant. All nuclear power plants use fission only. Fusion is much harder, but will be better if we can figure it out.
nuclear meltdown .-. '
It depends upon the rating of the plant. A typical plant will produce around 1100 megawatts per hour.
Not really. You receive 100 times as much radiation from coal power plant pollution than you do from nuclear power plant leaks.

Depends on the design.
Up to 1500MWe per reactor
123412
it costs 99 sents.
Depending on: - the type of the nuclear reactor - the electrical power of the nuclear reactor - the type of the nuclear fuel - the enrichment of uranium - the estimated burnup of the nuclear fuel etc.

1 plant takes 30million dollares
This depends on the type and power of the reactor; say tens of metric tons.
