An innovative power unit with a turbine unit manufactured by Power Machines is put into commercial operation

State-of-the-art Power Unit 4 with the BN-800 fast-neutron reactor has been put into commercial operation as per schedule. A relevant order was signed by Andrey Petrov, Rosenergoatom Concern General Director, on October 31, 2016 based on the approval of the Rosatom State Corporation.

Power Unit 4 of Beloyarsk NPP equipped with a fast-neutron reactor is an innovative Russian design in nuclear power engineering. It has monobloc arrangement that provides for a single high-capacity turbine in conjunction with a hydrogen-free turbogenerator characterized by high efficiency, heat-up margin and safety.

Power Machines' specialists designed, manufactured and supplied a 885 MW steam turbine complete with a 890 MW turbogenerator and auxiliary equipment to Beloyarsk NPP, supervised the installation of the equipment and managed the commissioning and startup.

Background:

The contract for supply of the machine hall primary equipment package for the Beloyarsk NPP power unit (with the BN-800 reactor plant) under construction was signed by Power Machines and Engineering Company ZIOMAR (a company of the Rosatom Machine-Building Division - Atomenergomash) in 2007.       

Power Unit 4 was connected to the grid on December 10, 2015. The program of works for power start-up at 50% capacity was completed on January 29, 2016. The power unit started operating at full capacity on August 18, 2016.
