The Unit-3 of Kudankulam Nuclear Power Plant (NPP) has taken a key step towards operationalisation with supply of main equipment for the plant ahead of PM Narendra Modi’s visit to Russia in September first week.
Andrey Lebedev, Vice-President for projects in India of ASE,Russia`s Rosatom State Atomic Energy Corporation Engineering Division, said that all main equipment have been supplied.
Rosatom State Corporation is main equipment suppliers and technical consultants for the Kudankulam Nuclear Power Plant project.
The shipment consisted of the molten core catcher, embedded parts of the reactor pit, dry protection, heat-insulation of the cylindrical shell/barrel, truss buckstay, reactor vessel. These are part of the enhanced safety features in VVER-1000 reactors. A thrust truss and devices for neutron flux monitoring chambers allocation are expected to be delivered by the next shipload.
A core melt localization device (CMLD), or a “core catcher,” is one of the most important passive safety systems of modern nuclear power plants of Russian design. CMLD is installed at the bottom of the plants’s protective shell. It is designed to localize and cool the molten core material in case of a hypothetical accident that could lead to damage to the core. The “core catcher” allows the integrity of the protective shell to be preserved and thus excludes radioactive emission in the environment, even if the hypothetical accident is serious.
The passive safety systems are capable of functioning even in the event of a complete loss of power supply. They can provide full safety without the active systems and an operator. For example, the passive heat removal system (PHRS) ensures long-term heat removal from the reactor core section if all the other power supply sources fail. If necessary, the system can switch on without external interference and function under the influence of purely natural factors.
“Taking into account that four steam generators, a pressurizer, main coolant pipelines and a bubbler were delivered earlier, ASE has mostly completed the procurement of the containment equipment for the third unit to ensure uninterruptible and continuous operations for the reactor plant construction which is on the critical path of the project,” said Lebedev.
Kudankulam NPP is being constructed in Tamil Nadu within the scope of Russian-Indian agreement of 1988 and its attachments dated 1998 and the Agreement as of December 08, 2008.
In October 2013 Unit-1 of the Kudankulam NPP was connected to the southern power grid. In August 2016 Unit-2 of the Kudankulam NPP was connected to the power grid. Unit-3 and Unit-4 of the Kudankulam NPP are under construction. The contracts for construction of Unit-5 and Unit-6 have been signed and the preparatory works are in progress.
Rosatom State Atomic Energy Corporation is the largest electricity generating company in Russia, providing over 18% of the country's energy needs. The company ranks first in the world in terms of the size of its foreign projects portfolio, with 36 power units in 12 countries at various stages of implementation. Rosatom ranks first in the world in uranium enrichment, second in the world in uranium reserves and fourth in terms of its production, and provides 17% of the nuclear fuel market.
Rosatom brings together about 400 enterprises and organizations, including the world's only nuclear icebreaker fleet. Together, they employ about 250,000 people.
