Rosatom and Kudankulam Deploy Fuel For Longer Nuclear RunsRosatom’s Nuclear Fuel Division supplied advanced nuclear fuel for the first loading of the VVER-1000 reactor at Unit 3 of India’s Kudankulam Nuclear Power Plant. The core innovation is the adoption of advanced TVS-2M fuel, which supports longer operating cycles and higher reliability. The TVS-2M fuel design incorporates a more rigid assembly structure, an upgraded anti-debris filter, and a higher uranium content per assembly. For energy consumers and utilities, longer fuel cycles translate into improved plant uptime, better cost efficiency, and more stable baseload power. By pairing fuel supply with ongoing engineering services, Rosatom and its Indian partners demonstrate how incremental fuel innovations can significantly boost performance and output at large-scale nuclear facilities.
