In the US they're stored on site.
All countries that have nuclear reactors have nuclear waste and it is always a problem, though a manageable one.
The amount of plutonium in the nuclear waste depends on the type of waste and its origin. If by waste, it is meant the spent nuclear fuel discharged from reactor after irradiation, then the plutonium amount depends mainly on the nuclear fuel initial enrichment, the neutron irradiation flux, and the time of irradiation.In usually operated nuclear power reactors of light water reactors, the discharged spent fuel contains roughly 1 kg plutonium per ton of fuel.
Nuclear plants
yes, Nuclear fission as used in nuclear power plants produces radioactive waste with long half lives. However, this creates no problems. This wastes are either confined in the spent nuclear fuel (that is stored either in wet storage or in dry storage facilities) or stored as vitrified nuclear waste.

Yes.
In the US they're stored on site.
Nuclear reactors produce heat, the heat then is used to make steam, turning turbines. Therefore, the waste of a nuclear power plant is excess steam.
Three problems associated with nuclear waste
they dump it in the ocean

Nuclear waste is typically stored in secure facilities called nuclear waste repositories. These repositories are specially designed to safely contain and isolate the radioactive waste from the environment for long periods of time.

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.
