The story

The company was established by the decree of Council of People's Commissars of the USSR on January 28, 1946 by the order of the People’s Commissar of the USSR heavy engineering on February 1, 1946.

In 1958, under an OKB project, equipment was manufactured for “Stand 27/VT,” a land-based prototype of a liquid metal cooled reactor for Project 645 atomic submarines, built in Obninsk at the industrial site of the Institute of Physics and Power Engineering. In 1961, the creators of the stand were awarded the Lenin Prize.
