The first Drawback of nuclear power is that "Radioactive Waste"
the Radioactive Waste contain radio isotopes with a long half-lives.
The radioactive wastes are usually buried under sand and vitrification.
it's dangerous and can leak radiations if not stored correctly.
These reactive radicals make the sand or the water contaminated. It is known as mixed waste. And the mixed wastes cause hazardous chemical reactions and leads to dangerous complications.
radio isotopes may produce dangerous levels of ionising radiation, which in sufficient doses can lead to illness or death.
and finally these wastes can be used to make nuclear weapons.
