The development of nuclear power has provided electricity for less money, but at a cost. what may be considered a "cost" of nuclear power? a) large amounts of energy are produced very cheaply. b) it takes a lot of energy to run a nuclear power plant. c) nuclear power plants provide new jobs for a community. d) the radioactive waste is unsafe and hard to store safely.

The answer is; D

Radioactive waste poses a serious challenge to the environment. Any leakage of the waste is risky because the radioactivity can flow up the food chain and it also takes time for it to decay and become less harmful. Therefore, its effect can be felt over many generations. Therefore, safe storage of radioactive waste is a challenge (and can be very expensive) and a deterrent for pursuing the potent energy source.
