The energy released in nuclear fission, mainly of uranium-235
Cut all of the power off
Depends on the design.
Effectively zero outside the plant boundary
None, that is for water type reactors, PWR and BWR.
As far as I know the last failure requiring a write off of the reactor was at Chernobyl in 1986.
It is safely disposing of the bits of a burned out power station. (As nuclear fission gives off neutrons, anything near a nuclear fission reaction itself becomes radioactive over time, so it is a big job to take down a power station safely)

No, they are actually giving off steam. The steam is a byproduct of the hot water from the turbines air cooling.
It depends what type of power plant. A coal-burning power plant will produce CO2 and SO2, which are both pollutants. Nuclear power plants and geothermal power plants produce steam, which is not a pollutant. There are many other types of power plants, but most produce CO2 and SO2 or steam.
About 19% of the electricity used is from nuclear power, but all the lower 48 states of the United States use some nuclear power. Alaska and Hawaii are separate. Electrical power is conducted on a grid. The power goes into the grid from various power stations, and is used by various users. If a power plant goes down, the grid distributes power continuously because other plants continue and take up the slack. There are not many people who can say their power comes from a specific power plant, and most of those are probably off grid users (people who generate their own power). One estimate is 180,000 families, which might be 900,000 people, are off grid. In addition, roughly 700,000 people who live in Alaska and 1,300,000 in Hawaii have power that does not come from nuclear plants. That totals about 2,180,000, or about 0.7% of the population of the United States who use no nuclear power.

A nuclear power station uses heat given off by the controlled fission of enriched uranium. The heat is used to boil water, the steam blows through the vanes of a turbine, and the turbine spins an electrical generator.
