Japan*s atomic watchdog cleared a nuclear restart for the first time since 2021, a shot in the arm for the government*s effort to increase power generation from the energy source and reduce dependence on fossil fuels.

The Nuclear Regulation Authority on Wednesday approved a preliminary report saying Hokkaido Electric Power*s Tomari No. 3 reactor meets post-Fukushima safety rules, according to a live stream of the hearing. Hokkaido Electric*s president said in March that he expected the unit to restart in 2027.

Although the government recently approved a new energy strategy to maximize the use of nuclear power, restarts of units shuttered following the 2011 Fukushima disaster have been slow. Fewer than half of Japan*s 33 operable reactors have resumed due to lengthy regulatory checks and upgrades, as well as local opposition.

After a public comment period, the regulator*s report will be subject to formal approval. The Tomari reactor has been shut since 2012.
