Japan: Approval to install treated water discharge facility at Fukushima Daiichi Nuclear Power Station

On 22 July 2022, Pursuant to the Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Nuclear Reactors, the Nuclear Regulation Authority (NRA) of Japan approved the installation of an Advanced Liquid Processing System (ALPS) treated water discharge facility at Fukushima Daiichi Nuclear Power Station. However, as clarified by the Ministry of Foreign Affairs of Japan:

“[T]his does not mean that TEPCO can immediately start the discharge of the ALPS treated water into the sea. Before doing so, remaining processes, such as NRA’s Pre-Service Inspections to check and confirm the installation status of the discharge facilities, will continue. The discharge of the ALPS treated water into the sea will not start until after these steps are duly taken. The IAEA will continue to conduct its independent review throughout, including while these steps are taken, and the Government of Japan will carefully consider the findings and observations from the IAEA’s review”
