CHENNAI:
Atomenergomash, a machine-building division of Russia’s Rosatom State Atomic Energy Corporation, manufactured and shipped out set of equipment for the Kudankulam Nuclear Power Plant (KKNPP) in Tamil Nadu, according to Rosatom.
The equipment includes Moisture Separator Reheaters and High Pressure Heaters for KKNPP Unit 3 as well as spare parts for the scheduled maintenance of Reactor Coolant Pumps at KKNPP Units 1&2, the Rosatom release stated.
Moisture Separator Reheaters, manufactured by ZiO-Podolsk, a subsidiary of Atomenergomash, are designed to remove water condensed from the process steam to maximize thermal efficiency and reliability of the low pressure turbine. The weight of equipment is 47 tones; height is 7 meters; diameter is 4 meters.
High Pressure Heaters with a length of more than 11 meters, that weigh 120 tones, pre-heat feedwater, delivered to a steam generator. The equipment is the one of the main elements of the turbine island, where the thermal energy is extracted from pressurized steam and converted into electrical energy.
The total weight of the equipment for KKNPP Unit 3 is more than 1000 tones. In total, there will be eight sets of Moisture Separator Reheaters and High Pressure Heaters.
Spare parts for the Reactor Coolant Pumps, manufactured by CDBMB (also a subsidiary of Atomenergomash) weigh 50 tones and include bearings, thrust rings and electromagnets. The Reactor Coolant Pumps are used to pump primary coolant (water) around the primary circuit to remove the heat generated in the reactor core.
The Kudankulam Nuclear Power Plant is jointly constructed by Rosatom State Atomic Energy Corporation and Nuclear Power Corporation of India Limited (NPCIL). Atomenergomash is the supplier of the main equipment for the reactor and turbine islands. The design and construction works on the site are being performed by ASE Group of Companies, an engineering division of Rosatom.
