In the matter of reopening nuclear reactors, he has critically pointed out an unreasonableness of the current severe radioactive level by reviewing both corporate and public literatures. As for the radioactive waste water contaminated with tritium, he proposed to hold in large scale tanks of long life, instead of releasing to the sea, waiting for attenuation. His reports have contributed to provide citizens the second opinions against TEPCO and the government.
