Japan PM calls for reactor shutdown

Reports CNN: "Japan's prime minister said Friday he has asked the operator to shut down the nuclear reactors at the Hamaoka nuclear plant until earthquake and tsunami protections can be built. The plant -- located on the Pacific coast in Omaezaki, southwest of Tokyo -- is vulnerable and could produce "grave damage to Japan" similar to the problems at the Fukushima Daiichi nuclear power plant that was damaged in the magnitude-9.0 earthquake and subsequent tsunami in March, Prime Minister Naoto Kan said."
