FILE - In this Oct. 16, 2008 file photo, Japan's then Atomic Energy Commission vice chairman Shunichi Tanaka delivers a speech at a meeting celebrating the 50th anniversary of the Nuclear Energy Agency, at the OECD in Paris. Tanaka, a nuclear physicist and Fukushima native is head of a five-member Nuclear Regulation Authority inaugurated in Japan, on Wednesday, Sept. 19, 2012. Opposition lawmakers and activists have raised questions about his credentials because he had been executive of the Japan Atomic Energy Agency, which promotes development of nuclear energy. Tanaka, 67, has helped decontaminate areas around the Fukushima plant contaminated with radiation. (AP Photo/Remy de la Mauviniere, File) less
