ZiO-Podolsk JSC (part of the machine-building division of Rosatom State Corporation – Atomenergomash JSC) has manufactured the heat-exchanging apparatus for the power unit No.5 of Kudankulam NPP. The relief tank has been prepared for shipment to India.
The specialists of JSC OKB Gidropress developed technical design. The employees of the Department of Nuclear Engineering Equipment of ZiO-Podolsk JSC developed the working design documentation. They also provide maintenance support for product manufacturing.
The relief tank is one of the important elements of equipment for NPP. It is intended for condensation of steam coming from the pressure compensator and other equipment of the primary circuit in the modes of heating and other operating modes of the reactor. The apparatus is made of austenitic chromium-nickel steel. The weight of the item is 15 tons, length – about 8 m, diameter – 2,5 m, height – 4 m. The lifetime of the equipment is 40 years.
In 2003-2004 ZiO-Podolsk manufactured and shipped equipment for reactor and turbine halls for power units 1 and 2 of Indian NPP: steam generators PGV-1000, moisture separator reheaters SPP-1000-1, high-pressure heaters PVD as well as 24 heat-exchanging modules of passive heat removal system (PHRS), pipelines of different purposes and filters.
