The VVER-1000 MWe reactor vessel for Kudankulam Nuclear Power Project's sixth unit in India, designed by Russia's Rosatom, is en route from Atommash, Russia. This marks a significant step in expanding KKNPP, highlighting Rosatom's global nuclear expertise.
Kudankulam Nuclear Power Project (KKNPP) - Sixth Unit Reactor Vessel Transportation
The VVER-1000 MWe reactor vessel for the sixth unit of the Kudankulam Nuclear Power Project (KKNPP) is being transported to its construction site in Tirunelveli district, India. This reactor is built based on a Russian design.
Key Details of the Reactor Vessel
- The reactor vessel weighs 320 tonnes and was manufactured at the Atommash plant, a division of Rosatom.
- The vessel embarked on its journey to India on the eve of 2025, after being loaded onto a river vessel and transported to the seaport of Novorossiysk for a 6,000-mile (9,656 km) sea voyage.
- A set of four steam generators for the reactor's sixth unit will also be shipped within the same year.
Current Status of KKNPP
- Four new 1,000 MWe VVER nuclear reactors are under construction at the site, following a Russian design.
- Two units with similar capacity have been operational since 2013 and 2016.
Role of Rosatom and its Divisions
- Rosatom State Corporation is responsible for the design, construction, and supply of equipment for KKNPP.
- They provide fuel for the power units throughout their entire lifecycle.
VVER-1000 MWe Series Reactors
- These reactors have proven reliability and efficiency over decades, with operations exceeding 2,000 reactor-years.
- They have potential for long-term use and are being considered for future nuclear power plants in the Far East.
Technological Advancements and Future Plans
- Rosatom is developing reactors with increased capacity and modern operational properties to enhance safety and economic efficiency.
Production and Quality Assurance
- OKB Gidropress is the main designer of reactor installations, overseeing all stages from technical design to operational support.
- Atommash produces complex equipment like reactors and steam generators for projects in Bangladesh, India, China, and Turkey.
- The production cycle for a VVER-1000 reactor vessel lasts two years, adhering to strict international quality standards with 289 control points.
- Inspections are carried out under the supervision of authorized organizations and foreign customers, with NPCIL representatives stationed in Volgodonsk since 2016.
