Original sentence: Its use is controversial due to the long term problems of storing radioactive waste, the potential for severe radioactive contamination by an accident, and the possibility that its use will lead to the proliferation of nuclear weapons.Proponents also claim that nuclear power is a proven technology which may be relatively rapidly built out if fossil fuels become depleted through peak oil or restricted due to environmental problems like global warming.Proponents argue that these risks are small and claim nuclear power generates relatively little airborne pollution
Edited sentence: Because nuclear power is a demonstrated technology, it could be rapidly built out in the future if fossil fuels are depleted or restricted for environmental reasons.Initially touted internationally as a post-nuclear-holocaust olive branch by President Eisenhower in his Atoms for Peace Campaign as a potential source of electricity abundant enough to share and "too cheap to meter", the dream of an atomic peace however was to end in a series of preventable nightmares which have etched both rational and irrational fears into the minds of several generations.Today, its continued use and expansion is a matter of heated controversy for a variety of stated reasons including: the challenge of securing radioactive waste for the thousands of years during which it remains dangerous, the uninsurable risk of severe radioactive contamination caused by willful negligence, and the gateway effect of nuclear energy on the proliferation of nuclear weapons
