Giving a leg-up to the construction work at the Kudankulam nuclear plant project, Atommash-AEM-Technologies, a part of machine-building division of Russian atomic energy corporation Rosatom, has started manufacturing a nuclear reactor and steam generators for unit No. 6 of the plant in Tamil Nadu. The reactor and steam generator shells have passed the inspection and items are at initial operations of the manufacturing cycle. Construction on the last unit (No. 6) was officially launched last December.
Within the frames of the contract for the fifth and sixth power units of the power plant, JSC AEM-Technologies will manufacture and supply two nuclear reactors with internals and an upper block of the VVER-1000 type, two sets of steam generators, reactor coolant pump set bodies, main circulation piping, emergency core cooling system tanks, passive core flooding system tanks and two pressurisers. The total weight of the items will be about 6,000 tonnes.
The reactor is an item of the first-safety class. It is a vertical cylindrical body with an elliptical bottom. The core and internals are located inside the vessel. Steam generator is a heat exchanger and a part of a steam-generating unit and weighs around 340 tonnes. The set of one NPP power unit includes four steam generators.
The first power unit of the Kudankulam plant has been steadily operating at the design capacity level of 1,000 MW since February 2016. The second unit was included in the national grid of the country in August 2016. The master framework agreement with Rosatom on the construction of the third and fourth units was signed in 2014. In June 2017, the engineering division of Rosatom and the Indian Atomic Energy Corporation signed an agreement on the construction of the third stage (units’ No. 5 and No. 6).
