Japan on June 20 said two ageing nuclear reactors can extend operations for up to two more decades -- the first such exception to stepped up safety rules imposed after the 2011 Fukushima nuclear crisis. The Nuclear Regulation Authority (NRA) said operation of the two ageing reactors at the Takahama nuclear plant can be extended for up to 20 years, saying the facilities "match" safety guidelines. / AFP / JIJI PRESS / JIJI PRESS / Japan OUT (Photo credit should read JIJI PRESS/AFP/Getty Images)
