A worker stands on the top floor of the No.5 reactor building, as visitors are reflected in a window, at Chubu Electric Power Co.'s Hamaoka Nuclear Power Station in Omaezaki, Shizuoka Prefecture May 17, 2013. Chubu Electric is spending at least $1.5 billion on safety upgrades at its Hamaoka nuclear plant southwest of the Japanese capital, to reduce the risk of a repetition of the disaster that hit Tokyo Electric's Fukushima station, when an earthquake and tsunami caused three reactor meltdowns.
