Background and Context

Indo-Russian Nuclear Collaboration

  • Partnership operates under a historic Intergovernmental Agreement signed in 1988
  • Technical support provided by Rosatom (Russia's state nuclear energy corporation)
  • Engineering executed by Atomstroyexport (ASE), a division of Rosatom
  • This represents one of India's largest nuclear energy collaborations

Technical Details

  • Reactor Technology: Russian-designed VVER-1000 (Water-Water Energetic Reactor)
  • Reactor Class: Pressurized Water Reactors (PWR)
  • Coolant and Moderator: Light water
  • RPV Significance: Often called the "heart" of a nuclear power plant; houses the reactor core where nuclear fission takes place

Installation Technique

  • Method: "Open-top" installation technique
  • Process: Heavy equipment lowered directly into reactor building using high-capacity crane
  • Advantage: Performed before containment dome erection and closure
  • Precision: Highly precise method for large component placement

Regulatory Framework

  • Atomic Energy Regulatory Board (AERB) granted clearance for:
  • Major equipment erection
  • Installation of key nuclear island components
  • AERB ensures safety standards in India's nuclear program
