Fukushima Daiichi Nuclear Power Plant “debris” storage method to be reconsidered – Chairman of the Regulatory Commission, Mr. Sarada

February 2, 2022

The chairman of the Nuclear Regulation Authority (NRA), Mr. Toyoshi Sarada, has asked Tokyo Electric Power Company (TEPCO) to reconsider the storage method of concrete debris with a very small amount of radioactive materials from the Fukushima Daiichi Nuclear Power Plant, with a view to temporarily burying it underground.

It has been 11 years since the accident at the Fukushima Daiichi Nuclear Power Plant occurred in March 2011. The decommissioning of the nuclear power plant involves the removal of nuclear fuel that has cooled down after melting down. The biggest challenge is to remove the fuel debris. On the other hand, the disposal of low-level radioactive waste, which is generated in large quantities every day at the decommissioning site, is also a major issue.

As a result of the hydrogen explosions in the three reactor buildings, concrete fragments were scattered.

At a meeting of the Nuclear Regulation Authority held on the 2nd, Mr. Sarada said, “Even if we assume that the waste will be transferred in the future, there are some areas where it would be much more advantageous to bury and store the waste,” and expressed his desire to ask TEPCO to reconsider the storage method with a view to temporarily burying it underground.

The amount of waste from the decommissioning of the nuclear power plant is increasing, but the management at the site is not up to the task, so a realistic storage method must be considered with an eye to the future, he said.

SEVEN YEARS AFTER: Radioactive debris piling up at Fukushima interim facility

Bags containing radioactive soil and other waste are piled up high at an interim storage facility in Futaba, Fukushima Prefecture, on Feb. 17.
FUTABA, Fukushima Prefecture–Stacks of soil and other waste contaminated by the Fukushima nuclear disaster continue to grow at an interim storage facility here.
Black bags filled with radioactive debris collected during decontamination work in various locations in the prefecture have been brought to the facility since October, when operations started.
Heavy machinery is used to stack the bags, and green sheets now cover some of the piles.
The town of Futaba co-hosts the crippled Fukushima No. 1 nuclear plant. The interim facility is expected to eventually cover about 1,600 hectares of land in Futaba and Okuma, the other co-host of the plant.
The government has acquired 801 hectares as of Jan. 29, and 70 percent of that space is already covered with contaminated debris.
Negotiations between the government and landowners are continuing for the remaining hectares.
The government plans to move the contaminated debris to a final disposal site outside the prefecture by March 2045. However, it has had difficulties finding local governments willing to accept the waste.

Burning debris from Fukushima

Local government officials, rather than objectively scientifically determine whether it was safe or not for the people just accepted the central government political decision to have debris from Fukushima brought and burned in many municipalities and prefectures throughout Japan.

As a result not only the Fukushima people have inhaled radioactive nanoparticles, but also many other people in other locations.

The map below, from year 2012, shows locations where Fukushima debris was burned then, it was really spread all over Japan during the first 3 years, 2011, 2012, 2013.



Today incineration of Fukushima debris continues in 19 locations in Fukushima prefecture…

James Fisher Nuclear Awarded Fukushima Daiichi Sampling Contract

British decommissioning and remote handling company James Fisher Nuclear announced Monday that it had been awarded a “high-value” contract from Japanese engineering company Mitsubishi Heavy Industries that involves developing technology to be used at the Fukushima Daiichi Nuclear Power Plant in Okuma, Japan.

JFN will be responsible for developing the latest technology to sample radioactive debris sitting below reactor cores at the power plant that suffered a triple reactor meltdown after backup power failed due to a massive tidal wave event in March 2011.

The specific value of the contract was not announced. JFN said it beat out the competition for the contract. Business director at JFN Bertie Williams said the expertise required for this kind of assignment was rare. “Few businesses in the nuclear arena realistically have the experience and personnel with the capabilities to take on such a challenging task,” Williams said.

The work involves taking samples of a variety of materials both above and below the water line at the damaged plant. JFN said it had been successful in demonstrating its technical design was “capable of addressing some of the most challenging conditions on Earth.” The goal is to evaluate the extent of the clean-up and decommissioning work needed at the plant.

Tokyo Electric Power : Giant vacuum cleaner used to remove radioactive debris in Fukushima

Tokyo, Jun 1 (EFE).- The operator of the plagued Fukushima nuclear plant has deployed a large device similar to a vacuum cleaner to clean up radioactive debris scattered over the plant’s Reactor 1, the company explained to Efe.

Technicians of Tokyo Electric Power (TEPCO) on Monday started using the apparatus, 13 meters high and 5 meters wide, which is operated through a crane and is capable of safely absorbing objects of up to 20 kilograms.

The top floor was rocked by an explosion caused by hydrogen concentration one day after being hit by the earthquake and tsunami that devastated northeastern Japan on Mar. 11, 2011.

The blast destroyed the roof of the plant, which remains covered with highly contaminated pieces of debris – from cement to metal fragments – and this will hinder the complicated process of removing the molten fuel inside the reactor vessel.

TEPCO plans to finish this operation in July and then proceed to remove larger debris.

According to the company’s roadmap, the withdrawal of molten nuclear fuel inside Reactor 1 is to be done within about four years.

The accident at the Fukushima Daiichi plant was the worst nuclear accident since the Chernobyl disaster in Ukraine in 1986. Its resultant emissions and radioactive discharges still keep thousands of people who lived near the plant out of the area and have severely affected agriculture, livestock and local fishing.
