Nuclear power is one of the more efficient and "clean" energy sources that we have in the modern era. It's even used to power multiple aircraft carriers, cruisers, destroyers, and submarines. With advancements in safety it can help in lowering emissions and can power whole regions effectively. To disregard nuclear because of "danger" is to ignore the number of catastrophes that have plagued other resources over the years. Similar to ignoring 30,000 car related fatalities in the US alone and blowing out of proportion the aviation related deaths worldwide, which is far smaller.
