Japan's new nuclear regulator will impose tighter safety standards for atomic plants, taking account of geological data in the earthquake-prone country, its head said on Thursday. Shuichi Tanaka, in an interview, also said his new body would have the authority to restart reactors idled since last year's Fukushima disaster once new safety standards were in place and met. Restarting such units is a key point in reducing the import bill for fossil fuels to produce electricity. REUTERS/Yuriko Nakao
