TOKYO (Reuters) - A former senior official of Japan's atomic watchdog has lashed out publicly at the agency's response to his concerns over the assessment of earthquake risks to nuclear plants, adding to a controversy over safety five years after the Fukushima disaster.
Former deputy chairman of the Nuclear Regulation Authority (NRA), Kunihiko Shimazaki, now a professor emeritus of seismology at the University of Tokyo, in June broke his silence after leaving the regulator in 2014 to voice his concerns that earthquake risks are not being sufficiently addressed.
