On 5 May 2011, workers were able to enter reactor buildings for the first time since the accident. The workers began to install air filtration systems to clean air of radioactive materials to allow additional workers to install water cooling systems.

Who cleaned up Fukushima?

In Japan, they're known as “nuclear gypsies,” an army of about 50,000 itinerant laborers recruited at low pay to clean up the radioactive debris and build tanks to store the unending flood of contaminated water that's generated to keep the reactor cores cool.

How is Fukushima water treated?

The water will be treated with an Advanced Radionuclide Processing System (ALPS) to reduce the concentration of radioactive materials (other than tritium) to below the international standard.

Is Fukushima still leaking into the ocean?

TOKYO — The operator of the wrecked Fukushima nuclear power plant said Wednesday it plans to build an undersea tunnel so that massive amounts of treated but still radioactive water can be released into the ocean less than a mile away from the plant to avoid interference with local fishing.

Is Fukushima reactor still hot?

In late March, the temperature inside the Unit 1 reactor exceeded 400 °C. It has now fallen to around 90 °C, and temperatures in Units 2 and 3 are also hovering around 100 °C. The cooling water injected into the reactor cores is being heated to boiling point, so workers must continually replenish it.

Is Fukushima still radioactive 2022?

Japan's industry ministry and the IAEA have agreed to compile an interim report on the water discharge plan in 2022. Officials say it is now safe to live in most areas around the plant except for its immediate surroundings after extensive decontamination work.

Is Japan going to release radioactive water into the ocean?

The Japanese utility giant Tepco is planning to release more than 1 million cubic meters of treated radioactive water — enough to fill 500 Olympic-size swimming pools — from the wrecked Fukushima Dai-Ichi nuclear power plant into the Pacific Ocean, part of its nearly $200 billion effort to clean up the worst atomic …

Can radioactive water be evaporated?

1 million gallons of radioactive water could be discharged into bay, evaporated or trucked elsewhere. One million gallons of radioactive water is inside a former nuclear power plant along Cape Cod Bay, and it has got to go.

How long will Fukushima be radioactive?

When the meltdown was occurring, the wind was blowing toward the northwest , contaminating a valley through the mountainous region. These areas still have relatively high radioactivity. The half-life of radiocesium is about 29 years, meaning the quantity of the radioactive material should drop by half by roughly 2041.

How long will Fukushima be uninhabitable?

100 years A large area around the Fukushima nuclear power plant will be uninhabitable for at least 100 years.
