A South Korean team of researchers has developed an innovative underwater laser cutting technology that will facilitate the safe dismantling of nuclear reactors, minimizing the risk of contamination, and can also be used for dismantling and nuclear weapons.
The corresponding development was carried out by the team of Dr. In-Dok Park from Korea Institute of Mechanical Engineering and Materials (KIMM).
It is noted that the new technology allows precise cutting of thick steel, used in nuclear pressure vessels, even at a depth of 10 meters.
«The technology of underwater laser cutting is significant, because it allows simulating the conditions of dismantling nuclear installations and significantly reducing secondary pollution during the process», — stressed chief researcher In-Dok Park.

The system is also equipped with a protective mechanism that prevents possible accidents in case of collision of the laser nozzle with the structure being dismantled.
To simulate the real conditions of dismantling, a special tank has been created that reproduces the conditions at a depth of up to 30 meters. The tank allows researchers to safely test technology, ensuring optimization of processes.
As you know, with the aging of the world's nuclear power plant fleet, the issue of safe and efficient decommissioning is becoming increasingly urgent.
According to the IAEA, by 2050 it is planned to stop and dismantle about 200 nuclear reactors built in the 1970s and 1980s. providing solutions that ensure a high level of safety and efficiency in the process of dismantling nuclear facilities.
