If there ever were a time that seemed ripe for nuclear energy, it's now.
For the first time in decades, popular opinion is on the industry's side. A majority of Americans thinks nuclear power, which emits virtually no carbon dioxide, is a safe and effective way to battle climate change, according to recent polls. At the same time, legislators are showing renewed interest in nuclear as they hunt for ways to slash greenhouse-gas emissions.
The industry is seizing this chance to move out of the shadow of Three Mile Island and Chernobyl and show that it has solved the three big problems that have long dogged it: cost, safety and waste. Researchers are working on reactors that they claim are simpler, cheaper in certain respects, and more efficient than the last generation of plants.
