How to clean Chernobyl from radiation?

Clean the Chernobyl zone of radiation.

In this article, you will learn:

How did they clean the Chernobyl zone of radiation?
Liquidators conducted a tunnel for 136 meters along for cleaning Chernobyl from radiation
The rain clouds were suppressed over the Chernobyl nuclear power plant for cleaning Chernobyl from radiation
What did then in Fukushima for work on cleaning up radiation?

Immediately after the accident, the circle of engineering tasks was determined. Perhaps the greatest danger was represented by the reactor itself. He could melt the base, and then the radioactive contamination would get into the groundwater, and through them into the river.

On top of the reactor sprayed materials from helicopters, it was also planned to build a sarcophagus, later named “Shelter.” This extra weight could press the base of even a stopped cold reactor. In order to avoid these risks, miners-tunnelers from Donbass were brought to Chernobyl.

They conducted a tunnel for 136 meters along for cleaning Chernobyl from radiation

They conducted a tunnel for 136 meters along the 4 th block for cleaning Chernobyl from radiation. In the tunnel, the rails were laid, a technique was put under the reactor, and the creation of a gigantic underground cavity under the reactor began. It was supposed to be equipped with fittings, temperature and radiation sensors, as well as pipes for supplying cooling and then concreted.

Between the nuclear power plant and the river Pripyat was also dug a three-kilometer concrete wall. She went to the ground to a depth of one hundred meters. Its goal was to prevent emissions from the river that happened during the accident and settled on the ground around the nuclear power plant and on the reactor itself.

The rain clouds were suppressed over the Chernobyl nuclear power plant for cleaning Chernobyl from radiation

From May to December (before the onset of stable frosts), The rain clouds were suppressed over the Chernobyl nuclear power plant for cleaning Chernobyl from radiation. The liquidators tried not to let the rain fall over the exclusion zone. With the first large rain, the radioactive stain would have become very blurred and got into the river. But rains in other regions brought with them emissions from nuclear power plants, raised by fire and wind. They were registered even in Scandinavia. In Chernobyl, concrete pumps of Worthington, Putzmeister and Schwing were used for concrete pouring.

What did then in Fukushima for work on cleaning up radiation?

Radiation in Fukushima. At the “Fukushima” sent a similar pump Putzmeister Holding with an arrow of 70 meters. There also flew a concrete pump Chinese Sany Group with a removal of 62 meters. Such machines are used to build skyscrapers, and in accidents they are needed to create a protective dome over the reactor zone. As a result of the explosion of the reactor and the fire, radioactive dust settled on the buildings of the Chernobyl nuclear power plant, fragments of the reactor and materials from the core were scattered there. The doses that these substances created were deadly to humans even at short intervals.

Many of the station personnel, firefighters and dosimetrists died from radiation sickness. To clean the surface of buildings used robots, manipulator-loader Forestry, crane and manipulator MG-3. A manual tool also went into the work – people worked on the roofs, despite the radiation doses they received.

Cleaning reduced doses on buildings, but the wind continued to carry out pollution. Then in the course polymeric coatings sprayed onto the contaminated areas by helicopters, as well as fire trucks and auto-pouring stations went into action. The coatings had to fix all the radioactive particles that the wind could carry.

At later stages of liquidation, the tasks of neutralizing contaminated plants in the exclusion zone were solved, which meant the removal of all vegetation – including trees – and its disposal in trenches. The grass, shrubbery and trees have been replaced by new ones. This was done to reduce the spread of dust from the contaminated zone.
