The nonprofit think tank Japan Forum on International Relations Inc. has issued a policy proposal calling for the restart of nuclear reactors after making every effort to improve their safety.

"Those nuclear power stations now . . . shut down should resume operations as soon as possible, after their safety has been verified, their facilities structurally reinforced, and their operational management improved in line with the lessons learned from the accident at the Fukushima (No. 1) nuclear power station," says a JFIR proposal released Monday.

The proposal was endorsed by some 70 academics and business leaders and submitted to Prime Minister Yoshihiko Noda last week.
