Hypothetically, if you could harness the power of an atomic bomb, how much power would that give you? Could you power a city with that amount of energy?

A megaton (a big bomb, about 50x more powerful than the WW2 bombs) is about 4*10^(15) Joules, or about a billion kilowatt-hours (kWh).  The average household uses about 10,000 kWh (electricity) per year, so this bomb would power 100,000 houses for a year.
