The NRA approved a preliminary report saying Hokkaido Electric Power ’s Tomari No 3 reactor meets post-Fukushima safety rules. Hokkaido Electric’s president said that he expected the unit to restart in 2027.

The Tomari reactor has been shut since 2012.

After a public comment period, the regulator’s report will be subject to formal approval.

Restarts of units shuttered following the 2011 Fukushima disaster have been slow. To date, fewer than half of Japan’s 33 operable reactors have resumed. This is due to lengthy regulatory checks and upgrades, as well as local opposition.
