The "Chernobyl incident" was a major nuclear accident in human history, 35 years ago. After years of cooling and the barrier provided by the protective measures built in time after the accident, this originally threatening nuclear power plant is no longer a threat.

Chernobyl, which seems to have returned to calm, still poses a great threat from the melted-down nuclear reactors. This core, which looks like an "elephant foot", has the potential to rekindle. In fact, the melted core is the core product of the nuclear power plant accident, and it also has a special term "Krem".
There have been a total of 5 Craims in history, from a number of nuclear power plant accidents. The Chernobyl "Krem" is more famous because the plant was designed to be more powerful. After the accident, the melted core reacted violently, accompanied by extremely high temperatures. The important hazard of a nuclear accident is that the radiation is very high, and the high temperature generated by Krem can melt the ground and sink continuously.

In order to prevent the core from sinking and polluting the groundwater, a "cooling zone" was built under it to prevent the "Klem" from continuing to descend. After the accident, the radiation value at the scene is very high, and there is a great safety hazard to understand the specific radiation value and other information. After making sure the elephant's foot didn't continue to sink, it took six months for the researchers to come back here to collect samples.
The Chernobyl nuclear power plant exploded instantly
At this time, the radiation of the Chernobyl core is still very high, with an hourly radiation value of 12,000 roentgen. People can't stay around it for long, and nuclear radiation kills the body's cells directly. The faster the metabolism, the faster the cells die and the faster they decay. People who have been irradiated by the radiation of the elephant's feet will watch the body organs gradually decay and eventually die in pain.
After studying the samples collected, the researchers confirmed that elephant feet would not continue to sink and contaminate the groundwater. Heavy protective concrete walls were then built around the plant, but the radiation did not stop because of the walls.
Ten years later, a radiation expert re-entered the Chernobyl nuclear power plant to figure out the specifics of the reactor core. According to his investigation, the original thick concrete wall could no longer block the radiation of the reactor core, and then people built another barrier on the periphery to finally control the leakage of radiation.

However, the core of the pile has not really cooled down after all, which is undoubtedly a potential hidden danger. In recent years, researchers have found that there is a large amount of rainwater in nuclear power plants, and if this rainwater meets the melted core, the cooled "Krem" may be re-ignited, and the consequences can be imagined.
After so many years, the "cooling belt" built under the core can no longer guarantee that the re-ignited core will continue to sink. Once the core sinks into the aquifer, it poses a great security threat to the surrounding area. Due to the timely detection, measures have been taken to prevent possible accidents.
"Krem" is ultimately a potential safety hazard, and if it is careless, it can cause irreparable consequences. Even after a few years, the core has cooled down completely, but it is not an easy task to handle. Radiation will always exist for a long time, and if there is no better protection, it is still very difficult to bury the core deeply.
This abandoned nuclear power plant has become a clear portrayal of the nuclear accident. Its existence may also be a wake-up call, the use of nuclear energy needs to ensure that the risk is controllable, do not do a good job of protective measures in advance, and wait until a nuclear accident occurs, and then deal with it is not so easy.
With the upgrading of nuclear reactor technology, safety has also been significantly improved, and accidents such as Chernobyl are rarely likely to occur again. The possibility of nuclear accidents caused by human factors is reduced, but it is not excluded that natural factors cause nuclear power plant accidents. It is crucial to take timely precautions before building a nuclear power plant.
