OREANDA-NEWS. December 28, 2011. The specialists of the leading assembly business unit in TITAN-2 Holding, Installation and Construction Directorate No. 90  have performed works to assemble the first condenser group equipment units in the turbine building of  power unit No.1 at Leningrad NPP-2. This is the first primary process equipment of turbine building of power unit No.1 at LNPP-2.

Today, the assemblers have installed 16 spring boxes which will become the foundations for the condensers. Condensate collectors have been assembled and mounted (the total weight of the parts is about 300 tonnes).

Also the installation of the first units of the lower and upper condenser group pipeline systems has started. The lower units of Condenser No. 2 with the total weight of 100 tonnes were the first to be installed. 800 tonnes of equipment are still to be installed to their intended places in the course of assembly works related to lower and upper units. The total weight of all the condenser group equipment is over 2000 tonnes.

Condensers of the turbine room are intended to cool the turbogenerating set of power unit No. 1 of LNPP-2. The main task of condenser installation is to make and to maintain negative pressure in the turbine’s exhaust hood, and by doing so – to make the same inside the condenser, as well.

To perform these works the TITAN’s crane Manitowoc 18 000 with the carrying capacity of 750 tonnes was moved from the reactor’s building to the turbine building of power unit No. 1. Totally, the crane movement, dismantling and assembly took about three weeks.
