The dispersal of radioactive wastewater from the Fukushima-Daiichi reactor disaster site to the Pacific Ocean is “in line with international safety standards” according to a task force set up by the International Atomic Energy Agency (IAEA), the UN’s nuclear power advocacy program, in a December 24, 2024 report.

Ever since the Tokyo Electric Power Co., or Tepco, first proposed pumping wastewater left from cooling Fukushima’s three hot piles of melted reactor fuel into the Pacific, the IAEA has supported, encouraged, and endorsed the plan, in spite of its own formal published guidelines which advise against it.

In June 2023, Dr. Arjun Makhijani of the Institute for Energy and Environmental Research, published a scathing critique of the IAEA’s approval, finding the oceanic pollution violates essential provisions of the agency’s own General Safety Guide.

The IAEA’s first 2023 report on the dumping scheme said the plan was “consistent” with its standards, and it claimed even before the first major release of the radioactive water that it would have a “negligible radiological impact to people and the environment.” Now the IAEA’s onsite laboratory in Japan has analyzed the first ten discharges that have been conducted between August 2023 and October 2024, Nuclear Engineering International reported.

The bulk of the radioactivity in the wastewater being pumped into the ocean is from tritium, the radioactive form of hydrogen, and carbon-14, neither of which can be filtered from water they contaminate. However, analyses of 1.3 million tons of waste coolant now stored in tanks shows a complex mix of other highly radioactive isotopes, including strontium-90, cesium-134 and -137, cobalt-60, americium, technetium, and even tellurium-127. In 2018, Tepco apologized for the failure of its giant filter system to separate all the materials it promised to, and has said it would repeatedly re-filter the contaminated water to try and remove 62 different reactor-borne isotopes before dumping it into the world’s largest ocean.

IAEA approval is license to copy bad actors
