TOKYO, July 22 (Reuters) - Japan's nuclear regulators have approved a plan to release water from the wrecked Fukushima Dai-ichi Nuclear Power Plant into the ocean, Kyodo reported on Friday.

The regulators deemed the release of the water, which is treated but contains traces of tritium, as safe, the report said.

The water was used to cool the reactors in the aftermath of the Fukushima Dai-ichi Power Plant nuclear disaster in 2011 and is now stored within the grounds of the power plant. (Reporting by Sakura Murakami; Editing by Jacqueline Wong)
