Dear scientist Joy, what you said is all rubbish. Nuclear reactors are as safe as any other power plant. Except Chernobyl no nuclear plant accident had been reported. Secondly nuclear plant have long pay back periods, but the cost of electricity is less because the running cost is less. Thirdly, we can use electric cars/buses or fuel-cell cars/buses with hydrogen as fuel. Hydrogen can be produced by electrolysis (cheap electricity from nuclear plants would be used).
