Rosatom, the renowned Russian nuclear energy corporation, has achieved a significant milestone by shipping a critical component for the fifth unit of the Kudankulam Nuclear Power Plant in India. The delivery was made from the production site of the Atommash Branch, AEM-Technologies, JSC in Volgodonsk, which is a part of Rosatom’s machine-building division called Atomenergomash.
The shipped component comprises thrust and supporting rings, which play a vital role in the construction of the fifth power unit at the Kudankulam NPP. These machined rings, equipped with slots, are specifically designed to secure the nuclear reactor in the central part and provide protection against vertical, horizontal dynamic loads, and seismic impact. Each individual item weighs approximately 20 tons and boasts a diameter of more than 5 meters. Notably, this marked the first time that two items were transported simultaneously using motor vehicle transport.
The journey of the equipment begins with its delivery to the port of St. Petersburg, from where it will be transported via water to India. The reactor, classified as an item of the first safety class, assumes the form of a vertical cylindrical vessel with an elliptical bottom. Inside the reactor, a core and internals are housed. The vessel is hermetically sealed by a cover, which is equipped with mechanisms, control and protection units, and outlets for in-core monitoring sensor cables.
The Kudankulam Nuclear Power Plant, situated in the southern state of Tamil Nadu, is a notable nuclear power project equipped with VVER-1000 power units. The construction of the Kudankulam NPP encompasses the establishment of six power units featuring VVER-1000 reactors, with a combined installed capacity of 6,000 MW. The first two power units were integrated into India’s national power grid in 2013 and 2016, respectively. Currently, work is underway to construct an additional four power units, representing the second and third stages of the Kudankulam NPP.
The shipment of the thrust and supporting rings signifies the continued progress and commitment to the development of the Kudankulam Nuclear Power Plant. The collaboration between Rosatom and its Indian partners in the project has been crucial in advancing the construction of this significant energy infrastructure. The successful transportation of these components further solidifies the close partnership and shared dedication to ensuring the safe and efficient operation of the nuclear power plant.
The Kudankulam NPP project holds immense importance for India’s energy landscape, as it significantly contributes to the country’s power generation capacity. With each new unit that comes online, India’s energy security and sustainability receive a notable boost. The project aligns with the nation’s goals of diversifying its energy mix and reducing its reliance on traditional fossil fuels, thereby promoting cleaner and more environmentally friendly sources of power.
The successful shipping of the thrust and supporting rings is a testament to the engineering prowess and meticulous planning involved in the construction of the Kudankulam NPP. It showcases the dedication and expertise of the teams involved in this significant undertaking, ensuring the adherence to the highest safety standards and the utilization of cutting-edge technologies.
As the construction progresses and more units of the Kudankulam NPP become operational, the project will continue to contribute to India’s energy needs and support its journey toward sustainable development. The collaborative efforts between Rosatom and its Indian partners exemplify the strong international cooperation in the field of nuclear energy, fostering technological advancements and facilitating the growth of clean and reliable power generation.
The successful delivery of the crucial component for the fifth unit of the Kudankulam Nuclear Power Plant reaffirms the commitment of all stakeholders involved to the long-term success of this ambitious project. It is a significant step forward in strengthening the energy infrastructure of India and underscores the close collaboration between Rosatom and its Indian partners. This achievement demonstrates the dedication and expertise of the teams involved in the project, ensuring the highest standards of safety and utilizing advanced technologies.
