Japan to begin treated Fukushima water release in two years

Plan criticised by Greenpeace.

Japan will begin releasing more than a million cubic meters of treated radioactive water from the wrecked Fukushima Dai-Ichi nuclear power plant into the Pacific Ocean in about two years, the government said Tuesday.

The controlled releases are expected to last decades. The plan was swiftly condemned by China’s Foreign Ministry and South Korea said that it posed a risk to the marine environment and the safety of neighboring countries. The US said the approach appeared to be in line with global standards.

“Disposing of the treated water is an unavoidable issue for decommissioning the Fukushima nuclear power plant,” Japan Prime Minister Yoshihide Suga said.

Laid waste by a nuclear disaster a decade ago, Japan’s Fukushima is still struggling to recover, even as the government tries to bring people and jobs back to former ghost towns by pouring in billions of dollars to decontaminate and rebuild.
The decision ends years of debate over how to dispose of the water that’s enough to fill more than 500 Olympic-sized swimming pools, which has been leaking into the power stations that suffered core meltdowns after an earthquake and tsunami in 2011. Discharges are common practice in the industry and Japan has said the releases will meet global guidelines.

While Tokyo Electric Power Co Holdings cycles in water to keep fuel and debris cool at the Fukushima site, about 100 cubic meters of groundwater flows in daily and becomes contaminated. The tainted water is pumped out and cleaned in a process that removes most of the radioactive elements except for tritium. Then it’s stored in one of roughly 1,000 tanks at the site that are forecast to be full by mid-2022.

Greenpeace criticised the plan and said there are other options Japan should consider.

“Rather than using the best available technology to minimise radiation hazards by storing and processing the water over the long term, they have opted for the cheapest option, dumping the water into the Pacific Ocean,” the group said in a statement.

A panel within Japan’s Ministry of Economy, Trade and Industry recommended last year that the water be released into the ocean or evaporated. The proposal stipulated that any water that’s released into the environment be re-purified and diluted to meet standards and that the discharges take place over decades, according to a December 2019 report from METI.

The International Atomic Energy Agency said in a report in April 2020 that those recommendations were “based on a sufficiently comprehensive analysis and on a sound scientific and technical basis.”

Despite criticism from neighbors including China, which said that Japan shouldn’t release the treated water into the ocean without full consultation and agreement with all stakeholder countries, the US said Japan has been transparent about its decisions.

Japan “appears to have adopted an approach in accordance with globally accepted nuclear safety standards” with regard to its decision on disposing radioactive water from Fukushima into the sea, US State Department spokesperson Ned Price said in a statement.

The ocean has become the world’s convenient garbage bin, and that is not right. We’ll all pay the price sooner or later.
