A protester (C) stands in front of a line of barricades as security personnel stand guard during a rally against the restarting of the plant in front of an entrance gate of Kyushu Electric Power's Sendai nuclear power station in Satsumasendai, Kagoshima prefecture, Japan, August 7, 2015. Japan is due to switch on a nuclear reactor for the first time in nearly two years as Prime Minister Shinzo Abe seeks to reassure a nervous public that tougher standards mean the sector is now safe after the Fukushima disaster in 2011. The head of Japan's atomic watchdog has said that the new safety regime meant a repeat of the Fukushima disaster would not happen, but protesters outside the Sendai plant are not convinced.
