Basically a very long time. Most radioactive isotopes are radioactive for a long time. Uranium 232 has a half life of 69 years and plutonium 238 has a half life of 88 years. Some isotopes are very long lived.
Iodine tablets are used in a nuclear accident to saturate the thyroid with non radioactive iodine. During a nuclear accident, radioactive iodine is released and the critical organ in the human body is the thyroid gland. Therefore if the thyroid is already full of non radioactive iodine the radioactive iodine can not be absorbed.
There are many ways a nuclear accident may occur, however most nuclear power plant accident occur due to problem in an reactor.
Electricity, but there is a risk of radioactive leakage.
The Chernobyl Nuclear Power Plant underwent a level 7 event - the worst accident so far. The plant, located in the Soviet Union near Pripyat in Ukraine lost its number four reactor on 26 April 1986. A link to the Wikipedia article on the accident is provided.
Yes; the average nuclear power plant yields about 3 tons of radioactive waste each year.

6.25% will remain radioactive.

The exact contents of radioactive waste from a nuclear power plant and radioactive fallout from a nuclear weapon can vary widely but are likely to be similar in their primary isotopes.The major difference between the radioactive waste from a nuclear power plant and radioactive fallout from a nuclear weapon is that the waste is normally contained and will not enter the environment (unless an accident happens) while the fallout is dispersed into the environment and is carried by the wind (sometimes all the way around the world multiple times).
Nuclear power accidents are a disaster. The 1986 nuclear accident at the Chernobyl Nuclear Power Plant in Ukraine was a catastrophic accident.

Chernobyl is famous for the worst nuclear power plant accident in history.
