Excerpt: State of #ContaminatedWater

"Contaminated water countermeasures at #FukushimaDaiichi #NuclearPower Station (#FDNPS) can be broadly divided into three areas: 1) Reduction of #groundwater flowing into buildings, 2) Reduction of #ContaminatedWater flowing into the sea, and 3) Reduction of the toxicity of contaminated water.

"Countermeasures implemented to reduce water inflow into the buildings are, from higher elevations downward, (A) Pumping up groundwater at the groundwater bypass and releasing it into the sea (953,611m3 up to February 10, 2025), B) Installation of a frozen earth barrier (on-land water barrier, total length roughly 1,500m) surrounding FDNPS Units 1-4, C) Pumping up water at the subdrains and releasing it into the sea (1,801,404m3 up to February 9), and D) Paving of the site with asphalt to suppress permeation of rainwater into the soil. Measures to prevent the discharge of contaminated water into the ocean include A) Groundwater leakage prevention by a steel water barrier on the sea-side and B) Pumping up of groundwater dammed up behind the sea-side water barrier from the well points and groundwater drains. Due to these measures, the volume of contaminated water discharged, 540m3/day in May 2014, fell to 80m3/day in FY2023, and was below 100m3/day in FY2024.

"In the reduction of the toxicity of contaminated water, cesium and strontium are removed, and after the removal of impurities using a reverse osmosis (RO) membrane, the multi-radionuclide removal equipment (ALPS – Advanced Liquid Processing System) then removes 62 radionuclides [NOT COMPLETELY!!!]. The water is then stored in tanks (containing 1,297,190m3 as of January 30, 2025. However, due to past equipment #malfunctions and operational policies, around 64% of the stored water exceeds the notification concentration).

"Oceanic release of the ALPS-treated contaminated water began on August 24, 2023, a total of 78,285m3 being released in ten batches by January 2025. Table 2 shows the amounts released in each release and the total amount of tritium released. The concentration is gradually rising. One further release is scheduled during FY2024. In addition, roughly 15,720m3 of water remain in buildings, and a further 8,946m3 of strontium-treated water, etc., 5,644m3 of water treated by RO, and 9,463m3 of concentrated wastewater, etc. also exist onsite."

Speaking of #Fukushima...

Editorial: Unresolved disposal of Fukushima #nuke disaster soil a barrier to full recovery

January 10, 2025

"The recovery of #FukushimaPrefecture cannot be considered complete until the disposal of soil generated from #radiation #decontamination work after the 2011 #FukushimaDaiichi #NuclearPlant triple-meltdown is resolved.

"The nuclear accident released vast amounts of #radioactive material over a wide area. The decontamination efforts in residential and agricultural areas across Fukushima Prefecture resulted in the collection of approximately 14 million cubic meters of contaminated soil. This soil has been transported to interim storage facilities built in the towns of #Futaba and #Okuma, where the power plant is located.

"Local communities only agreed to the construction of these facilities on the condition that the soil would eventually be disposed of outside the prefecture. By law, final disposal must be completed by March 2045, 30 years after storage began. To meet this deadline, the Japanese government held a meeting involving all Cabinet members late last year. The goal is to draft a concrete timeline for disposal by this summer.

"The government has also proposed reusing soil with radiation levels below a certain threshold. The plan envisions using the soil for public projects across the country, including road embankments and #farmland development.

"In Fukushima Prefecture, pilot projects are underway to confirm that reusing the soil is safe. In September 2024, the International Atomic Energy Agency (#IAEA) concluded that the government's plan complies with its safety standards. However, scientific assurances on safety alone have not been enough to advance the plan. Concerns about potential health risks and local reputational damage remain unresolved.

"In 2022, the Ministry of the Environment attempted to reuse the soil at three facilities it manages, including Shinjuku Gyoen National Garden in Tokyo, but the plan was derailed by strong opposition from residents. To this day, there is no clear timeline for implementation.

"Additionally, about a quarter of the removed soil is still too highly contaminated to be reused. This portion will require final disposal outside Fukushima Prefecture, but no schedule or location has been determined.

"Public understanding of the issue remains insufficient. A December 2023 survey conducted by the Ministry of the Environment revealed that over 70% of people outside Fukushima Prefecture were unaware of the plans for reusing or disposing of the soil.

"The electricity generated by the Fukushima Daiichi plant was primarily consumed in metropolitan areas, especially the Tokyo region. Dealing with the waste soil is a responsibility that must be acknowledged by those who benefited from that power.

"Meanwhile, the decommissioning of the plant is behind schedule, and those displaced from their hometowns around it are growing increasingly anxious. It is the government's responsibility to urgently present a clear path forward to address the aftermath of the nuclear disaster."
