Japan on Monday began a new round of discharge of nuclear-contaminated wastewater from the crippled Fukushima Daiichi Nuclear Power Plant into the sea, marking the 21st such release since the controversial operation began in 2023.
The discharge started at 11:41 a.m. local time. According to the plant's operator, Tokyo Electric Power Company Holdings (TEPCO), the latest round, scheduled to continue through July 24, will release about 7,800 tonnes of wastewater into the ocean, containing approximately 1.3 trillion becquerels of radioactive tritium.
Struck by a 9-magnitude earthquake and the ensuing tsunami on March 11, 2011, the Fukushima nuclear plant suffered core meltdowns that released radiation, resulting in a level-7 nuclear accident, the highest on the International Nuclear and Radiological Event Scale.
Despite concerns and opposition from the international community, Japan unilaterally launched the discharge of nuclear-contaminated water from the Fukushima Daiichi plant into the ocean in August 2023. So far, TEPCO has completed 20 rounds of discharges, and around 157,000 tonnes of wastewater have been released into the sea.
