The dome of the reactor building of Unit 3 has been installed in design position at Kudankulam NPP construction site (Republic of India, general designer and general contractor - ROSATOM Engineering division).
The lifting of metal structure of the reactor building dome began on November 30 at 6-30 local time. Prior to that, the two main parts of the dome - the lower part (Dome-2) and the top (Dome-3), had been pre-assembled on the ground. The assembled structure was raised to the height of 62 meters by heavy crane Liebherr LR 11350 and installed in the design position. The operation lasted for 1 hour 15 minutes, the total weight of the structure is 281.6 tons, and its weight with the rigging is 304.92 tons.
The use of technology of pre-assembly on the ground and installation of one structure instead of two, made it possible to reduce the duration of construction and installation works at the reactor building by almost one month. Placing the dome in the design position ensures the possibility of establishment of the finishing installation area for the main coolant pipeline . Works for coupling of the pipeline are currently under way.
“We share our experience and our technologies with our partners, we perform the necessary training and fulfill all the undertaken obligations”, said Andrey Lebelev, Vice President of ASE JSC for Projects in India. “This allows us to be confident in the quality of our products and services, maintain the trust-based relations and remain the global leader in the application of Russian technologies at power units built abroad.”
Power units No 3,4 and 5,6 are the second and the third stages of Kudankulam NPP constructed under AES-92 design with VVER-1000 (V-412) reactor type. The technical solutions implemented in Kudankulam design characterize further evolutionary development of VVER-reactor NPPs of high power and transition to creation of a new, reliable, safe and feasible power unit. New power units of Kudankulam NPP comply with the most up-to-date safety requirements of IAEA.
The developer - the technical customer of the facility - is Nuclear Power Corporation of India. The general designer and supplier of equipment is JSC ASE. Currently, power units No. 1, 2 of Kudandulam NPP are operating at the capacity established by the operation schedule.
ROSATOM Engineering Division unites the leading companies of the nuclear industry, namely: Atomstroyexport JSC (Moscow, Nizhny Novgorod, branches in Russia and abroad), Joint Design Institute - Atomenergoproekt JSC (Moscow, Nizhny Novgorod, St. Petersburg branches - design institutes, branches in Russia and abroad, R&D branches) and subsidiary construction organizations. The Engineering Division ranks first in the world by the order portfolio and the number of NPPs constructed simultaneously across the world. About 80% of the Division’s revenues originate from foreign projects. The Engineering Division implements construction projects for high-power NPPs in Russia and across the world, renders a full range of EPC, EP, EPC(M) services including project management and design activities, and develops Multi-D technologies for the management of complex engineering facilities. The Division relies on the achievements of the Russian nuclear industry and innovative state-of-the-art technologies. www.ase-ec.ru
