The tritium level in the ocean near the Fukushima No. 1 nuclear power plant was well below the operational limit of 700 becquerels per liter, the plant operator said Friday, the day after it began discharging treated water from the plant.

Tokyo Electric Power Company Holdings (Tepco) said that the tritium level in the Pacific Ocean, where treated water from the plant has been discharged, was below about 10 Bq per liter in all 10 locations it surveyed.

“By quickly sharing the survey result, I hope we will help wipe away people’s concerns,” Keisuke Matsuo, Tepco’s spokesperson on the decommissioning process, said in a news conference.
