Classified Underground Facility
In the spring of 1982, the Classified Underground Facility was built by the EAC Foundation, in order to study and test new nuclear and thermonuclear technologies. Scientists wanted to implement project 'Little Sun' in the facility.
The 'Little Sun' project is a project to create a thermonuclear reactor based like our sun, but very small in size. The goal of this project was to successfully activate the reactor, rate its stability and monitor the reactor.
