Kudankulam. Russia delivers 187 ton pressure equipment to India for Unit 5 of Kudankulam N plant

NEW DELHI. Mechanical Engineering Division of the Russian Atomic Energy Agency “Rosatom”, AEM-Technologies Izhorashipped 187 tons of suppressors for 5 units Kudankulam nuclear power plant. The product was shipped to India on April 3 and will travel over 17,000 km to its destination in Tamil Nadu. The pressurizer is called the main switchgear of the VVER reactor and is responsible for creating and maintaining pressure and coolant volume. It is used to limit pressure fluctuations in transient and emergency modes. When assembled, it is about 14m long and 3.3m in diameter. Its capacity is 79 cubic meters, wall thickness is 152 mm.
During the hydraulic test, the equipment passed the hardness test at high temperature and maximum allowable pressure of 24.7 MPa. The Kudankulam plant will include 6 power units with VVER-1000 type reactors with an installed capacity of 6000 MW. The first phase, consisting of units No. 1 and No. 2, has already been connected to the national grid in 2013 and 2016, respectively. Currently, the construction of nuclear power plants 3, 4 and 5, 6, which are the second and third stages of the nuclear power plant, continues.
NPCIL and Rosatom completed reactor design and engineering supervision arrangements in 1998 for the construction of the first phase of the KNPP at a cost of 140 billion rubles ($2.47 billion). The total cost of the project for the six units is approximately 1.11 trillion rubles ($16.3 billion). The production period of the Kudankulam plant is 60 years, which can be extended for another 20 years.
The first unit supplies electricity at a cheaper rate of about Rs 3.89 per unit. The plant’s home state Tamil Nadu is allocated 50% of the power generated (925 MW), while neighboring states share 35% of the remaining power: 442 MW in Karnataka, 266 MW in Kerala and 67 MW in Puducherry. The final 15% of the energy produced is undistributed and will be added to the central pool.
