VIENNA, February 29./TASS/. The tritium concentration in the fourth batch of the ALPS treated water from Japan's Fukushima nuclear power station, which began to be discharged into the ocean on Wednesday, is far below the operational limit, the press service of the International Atomic Energy Agency (IAEA) said referring to data from the organization's experts.

"Experts stationed at the IAEA’s office at the site of the Fukushima nuclear power station (FDNPS) took samples after the treated water was diluted with seawater in the discharge facilities on 28 February. The IAEA’s independent on-site analysis confirmed that the tritium concentration is far below the operational limit of 1,500 becquerels per liter," the agency said.

On Wednesday, the operator Tokyo Electric Power started releasing a fourth batch of treated water from the nuclear power plant into the ocean. At this stage, it is planned to discharge about 7,800 tons of treated water in batches not exceeding 500 tons per day. This stage will last until March 16.

Earlier, the Japanese Foreign Ministry announced that an IAEA delegation headed by the agency’s Director General, Rafael Grossi, would arrive at the station in mid-March for another inspection. In particular, the IAEA chief will review water discharge as well as will meet with the authorities of Fukushima Prefecture and local residents.
