If you mean nuclear plants, the total is something over 400 individual reactors
As a natural element curium exist in infinitesimal amounts in uranium ores.Artificial curium is from nuclear wastes, nuclear reactors burned fuels, nuclear weapons tests.
nuclear power is going to be around for much longer, more fission reactors will be built to compensate in the increase in energy usage and more research is being done to make fusion energy which will replace fission reactors(this is quite a while yet before fusion reactors can be used to produce use usable energy for long periods of time).
in nuclear reactors and particle accelerators
Uranium is a non-renewable fuel. The earth has a limited supply of this mineral. Uranium ore is mined, then refined for use in power plants. It can not be put back. The earth is not creating more uranium. As with any non-renewable fuel, we should be concern about the supply. If additional quantities are discovered, the uranium that is known to us, can increase. See related link on abundance of uranium and other minerals.
There are 59 nuclear reactors in France.
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
There are over 400 nuclear reactors around the world.
As of 2010, India has 20 Nuclear Reactors.
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
Sweden currently has 3 active nuclear power plants with 10 reactors.

Radioisotopes for many uses (e.g. medical, industrial, scientific) are produced in nuclear reactors.
Nuclear reactors use nuclear fission.
90 occur naturally - others have been made in nuclear reactors etc
Well, you don't let them near nuclear reactors, but, if it did happen, they would probably die of radiation. Anyway, not many animals are near nuclear reactors.
There are currently (year 2013) 31 countries having nuclear power reactors. The rest are not having nuclear power.
