The last two containers of the ultrafiltration facility for chemically demineralized water preparation have been installed at the Leningrad NPP 1st power block substitution capabilities’ construction site.

Each container weighs around 10 tons. They were installed on the foundation using GROOVE cranes that can handle up to 50 tons. Later on, the containers will undergo pipes fitting.
