Detailed explanation-1: -Disposal of low-level waste is straightforward and can be undertaken safely almost anywhere. Storage of used fuel is normally under water for at least five years and then often in dry storage. Deep geological disposal is widely agreed to be the best solution for final disposal of the most radioactive waste produced.
Detailed explanation-2: -A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
Detailed explanation-3: -When used nuclear fuel bundles are removed from a reactor, they are placed in a water-filled pool where their heat and radioactivity decrease. After seven to ten years, the bundles are placed in dry storage containers, silos or vaults.
Detailed explanation-4: -Right now, all of the nuclear waste that a power plant generates in its entire lifetime is stored on-site in dry casks. A permanent disposal site for used nuclear fuel has been planned for Yucca Mountain, Nevada, since 1987, but political issues keep it from becoming a reality.
