On the reactor building of the power unit No. 4 under construction has been mounted the second circle of the protective cover consisting of 12 integrated blocks in total weight of 625 tons.

This transaction, as well as installation of the first circle, was performed by "Rosspetsenergomontazh Trust". On the cooling vaporizing tower of the power unit No. 4 concreting of the fifteenth circle has been also completed.

On the power unit No. 3 preparation for a stage of ropes tension of the Protective Cover Pretension System  (SPPC) has been conducted. The system provides additional margin of safety in case of any accidents with a decompaction of the main circulating contour and protects the power unit and reactor installation from external impacts, including a plane crash. SPZO consists of special metal ropes, and process of a tension has been carried out according to the certain scheme and in some stages.

Preparation for transfer of the reserve second and third cell of diesel-generator power plant (RDES) in commissioning has been also conducted. In the reactor building of the power unit No. 3 main circulating pipeline (MCP) installation is being proceeded.

In total specialists of JSC "Sezam" should execute 28 welded seams. Today 7 seams has been welded 5 more are in work. The main circulating pipeline with an internal diameter of 850 mm, general long more than 130 meters connects the capital equipment of the first contour: reactor, steam generators and main circulation pulsers. GTsT is intended for heat carrier circulation under a high pressure.

Start-up of the power unit No. 3 is planned for 2014.

The Rostovskaya nuclear power plant is a branch of JSC "Concern Rosenergoatom". The nuclear station is located on the bank of the Tsimlyansk Reservoir in 13,5 km from Volgodonsk. At nuclear station two power units with VVER-1000 reactors with an installed capacity of 1000 MWt are operated. The power unit No. 1 is put into commercial operation in 2001, the power unit No. 2 – in December, 2010.
