According to a report from Kyodo News Agency on June 10, Tokyo Electric Power Company plans to discharge nuclear sewage from the Fukushima Daiichi Nuclear Power Plant into the sea in two years. In order to keep the radioactive tritium concentration in nuclear sewage lower than the standard value, it will be used before being discharged into the sea. Seawater is diluted, but Tepco’s current policy is not to measure the concentration of the diluted nuclear sewage, and will only rely on calculations to determine whether it meets the standard.
According to the report, the Japanese national standard for radioactive tritium is an average of 60,000 becquerels per liter of water, and Tepco has independently set a standard of 1,500 becquerels per liter, and plans to dilute nuclear sewage 100 times with seawater and discharge it.
However, Tepco’s current policy is not to measure the concentration of the diluted nuclear sewage before it is discharged, and will only rely on calculations to determine whether it meets the discharge standards.
