A girl blindfolds another as they play a game in Sakhari Nate village, near the proposed site of the Jaitapur nuclear plant in Ratnagiri district, about 360 km (224 miles) south of Mumbai, April 13, 2011. The stakes are high for chronically power-short India. The plant would eventually have six reactors capable of generating 9,900 megawatts of electricity -- enough to provide power to 10 million Indian homes. Long-running opposition to the proposed plant at Jaitapur has hardened amid the unfolding nuclear crisis in Japan, with village posters depicting scenes of last month's devastation at the Fukushima plant and warning of what could be in store for this region in the Western Ghats north of Goa.
