It’s been almost a year since a devastating earthquake and tsunami crippled Japan’s Fukushima Daiichi nuclear complex, leaving the country’s once popular energy program in shambles. In response, Germany decided to abandon nuclear energy entirely. Should the U.S. follow suit? FRONTLINE correspondent Miles O’Brien examines the implications of the Fukushima accident for U.S. nuclear safety, and asks how this disaster will affect the future of nuclear energy around the world. In particular, he visits one emerging battleground: The controversial relicensing of the Indian Point nuclear plant, located only 38 miles from Manhattan. What lessons can be learned from the disaster in Japan?
