It's definitely possible to have safe nuclear reactor supplied energy. The trouble is that several past catastrophes tarnish its reputation to the point of driving coalitions to seek the banning of nuclear energy. At this point in time, it is the most efficient form of energy with minimal carbon footprint. It would be senseless to abandon it. This form of energy would be a transitional one, until wind, solar and thermal generated energy technologies are perfected enough to make households largely independent of a massive energy grid.
