Tokyo Electric Power Company (TEPCO) announced on Thursday that it had resumed discharging wastewater from the Fukushima Daiichi Nuclear Power Plant after operations were automatically halted the previous day due to a system alarm.

The discharge was suspended a day earlier, when an abnormal alarm was triggered during a wastewater transfer operation.

TEPCO began the 20th round of wastewater discharge on June 1. According to the company's plan, the current round will continue through June 19, during which approximately 7,800 tonnes of wastewater containing about 1.3 trillion becquerels of tritium will be discharged.
