The reluctance to embrace nuclear power comes down to two primary obstacles: safety and costs. notorious plant accidents decades ago at chernobyl and three mile island gave serious pause about the safety of nuclear generators, and while safety technology has improved, questions linger on how to properly store nuclear waste.aside from safety concerns, or perhaps a result of them, the cost of producing nuclear energy has soared over the past 25 years to prohibitive levels. existing infrastructure is inadequate for any sizable expansion of nuclear power facilities, and only a handful of firms worldwide are qualified to construct nuclear power facilities. lastly, reduced interest in nuclear energy has dissuaded younger engineers from entering the field, sapping potential for growth.
