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."

Tritium Fact Sheet | SimplyInfo.org

"Tritium concentrations in the stored water vary greatly. Some tanks have lower levels of tritium concentrations while other tanks are incredibly high in tritium. A spot review of tritium concentrations found in the storage tanks ranged from 140,000 Bq/L to 2.5 million Bq/L per Japan’s nuclear regulator’s records.

"Tritium isn’t the only contaminant in this water TEPCO plans to dump into the Pacific ocean. The total of “other nuclides” that remain in the post-ALPS water is almost equal to the amount of tritium in the water. We have older reports that confirm the concentration of some of these other contaminants but don’t have specific values for some of the other ones such as Co-60, Sb-125, or the trace amounts of Cs-137 or Sr-90.

"Contaminants we are able to provide an estimated total for include:
I-129 82,633,197,600 bq
Ru-106 122,886,990,000 bq
Tc-99 78,381,972,000 bq

"TEPCO and other vested interests have attempted to distract from the volumes of contamination that would be dumped into the Pacific Ocean by claiming they will dilute it before dumping. This is akin to putting an equal amount of something into a tub with an eyedropper or pouring it in all at once out of a cup. The same amount ends up in the body of water. The delivery method is largely irrelevant to the concerns for the environment and public health."
