To deal with concerns about electricity shortages this winter, Prime Minister Fumio Kishida said Thursday that he will push to have up to nine nuclear reactors in operation by then.

But while 10 reactors are officially listed as having been restarted, only five are actually providing power. One of them, Genkai No. 4 in Saga Prefecture, will soon be offline to finish necessary safety work for the winter.

The other five are sitting idle because they are either finishing safety work needed to be switched back on, or they are offline for regular inspection.
