The Indian Atomic Energy Regulatory Board has authorized the installation of main power equipment at the fifth and sixth power units of the Kudankulam NPP. The decision was made after a multi-level safety review and verification of the project's compliance with global standards set by the International Atomic Energy Agency. This was reported by the Nuclear Power Corporation of India Limited (NPCIL).
The regulator's approval allows for the installation of critically important equipment: reactor vessels, steam generators, and cooling system pumps.
Rosatom emphasized that this stage marks an important milestone in the country's nuclear energy development and a step towards ensuring safe and reliable energy supply.
The nuclear power plant is located in the state of Tamil Nadu in southern India. The project includes six power units with VVER-1000 reactors with a total capacity of 6 GW. The first two units have been operating since 2016–2017, and four more are at various stages of construction. In April 2026, the active phase of commissioning work began on the third power unit.
The safety review that the project underwent included an assessment of design solutions, emergency protection systems, and compliance with environmental requirements. The regulator's experts confirmed that construction is being carried out in accordance with the best international practices. This allowed for a seamless transition to the next technological stage.
