Rosatom Sets 2026 Start for Kudankulam Unit 3 Commissioning After First Fuel Delivery

The six‑reactor project in Tamil Nadu anchors a fuel supply agreement exceeding $7 billion that Rosatom calls the largest on record.

Overview

  • Rosatom chief Alexey Likhachev said start-up operations for Unit 3 will begin in 2026, with subsequent units slated to come online year by year.
  • Units 3 and 4 are reported to be in a high state of readiness, while construction continues on Units 5 and 6.
  • The first batch of nuclear fuel for Unit 3 has been delivered under a long-term contract valued at more than $7 billion, which Likhachev described as unprecedented in scale.
  • Units 1 and 2 remain in commercial operation at outputs above their nominal 1,000 MW rating, supplying stable power to southern India.
  • After talks with Prime Minister Narendra Modi, President Vladimir Putin said bringing the plant to full capacity will strengthen India’s power system and outlined potential cooperation on small modular and floating reactors as well as non-energy applications.
