Recently ,TVEL Fuel Company of Rosatom of Russia supplied the first batches of more reliable and cost-efficient nuclear fuel over the existing one, the TVS-2M nuclear fuel, to India for the Units 1 & 2 of Kudankulam Nuclear Power Plant (KNPP)

About 

  • TVEL has fulfilled the agreement with Nuclear Power Corporation of India Limited (NPCIL) on implementation of a comprehensive engineering project, including introduction of TVS-2M nuclear fuel and elongation of the fuel cycle from 12 to 18 months for both VVER-1000 reactors.
  • Benefits 
    • due the rigidity of a fuel bundle makes it more efficient and more vibration-resistant.
    • The new fuel has increased uranium capacity – one TVS-2M assembly contains 7.6% more fuel material as compared to the earlier fuel bundles.
    • In addition, the special feature of the Kudankulam fuel in particular is the new generation anti-debris filter protecting bundles from debris damage, which may be caused by small-sized objects in the reactor core.
    • Operation in larger fuel cycles also enhances economic efficiency of a plant, as reactors have to undergo stoppage and refuelling less frequently, so the power units produce more electricity,”

Additional Information

  • Russia is building the KNPP under an Inter-Governmental Agreement (IGA) of 1988 and follow-on agreements in 1998 and 2008. 
  • The first stage, consisting of power units No. 1 and No. 2, was commissioned in 2013 and 2017, respectively. Power units No. 3,4 and No. 5,6 are the second and third stages of KNPP which are currently under construction.
