On the power station sites mostly
In the US they're stored on site.
For now nuclear waste is stored on site where the waste was generated. In a few years US will begin to store nuclear waste in Yucca Mountain, Nevada but no official date has been set.
On the power station sites, in water filled tanks or sometimes after some years in dry stores
Nuclear fuels is not only bad for us, but for the enviornment. Some nuclear plants dump nuclear waste in rivers, oceans, lakes and ponds. This can kill and injure living organisms including us. It is not even good to bury it in the ground. Nuclear waste has to be specially desposed.
They are making nuclear weapons.
The only form of nuclear energy currently used in the US, or anywhere in the world for that matter, to produce electricity is nuclear fission. There are ongoing experiments to attempt to use nuclear fusion, but the technological problems with that have not paid off yet.
No. But old ones are being refurbished.
US, UK, Russia, France, China, India, Israel, Pakistan, North Korea, South Africa are the countries that currently have nuclear weapons.
Nuclear power plants in the US produce approximately 2,000-2,300 metric tons of radioactive waste each year. This waste is mainly in the form of used nuclear fuel, which is stored on-site at the plants until a long-term disposal solution is established.
if the US did make 32000 nuclear weapons (it did not) they all can be dismantled and put into civillian nuclear reactors, where the fission process converts the plutonium into other (slightly weird) by producucts. If you are wondering about the amount of waste made by the original breeder reactors, just as much as a normal reactor.
It currently provides 19 percent of electricity in the US and a little less world-wide
None, the US currently only refurbishes existing bombs.
