This week we’re looking at nuclear power around the world, in light of the growing crisis at the Fukushima power plant in Japan. Today, we focus on an outlier in the nuclear community: India. The south Asian nation possesses nuclear weapons but never signed the Non-Proliferation Treaty (NPT). That made it an outcast amongst NPT nations for decades.  The situation changed in 2008, when the U.S. began to cooperate with India on nuclear energy issues. Sumit Ganguly, director of research at Indiana University’s Center for American and Global Security, discusses how this deal has impacted India’s energy sector.
