Russia supplies new fuel for Kudankulam reactors

Tags: Science and Technology National News

Russia's Rosatom State Corporation has supplied the first batch of TVS-2M nuclear fuel, which is a more reliable and cost-effective nuclear fuel, to India for Units 1 and 2 of the Kudankulam Nuclear Power Plant (KNPP).

  • Once the new TVS-2M fuel is in use, the reactor will start operating with a fuel cycle of 18 months.

  • This means that the reactor, which has to be shut down every 12 months to remove spent fuel and insert new fuel bundles and associated maintenance, will now have to shut down every 18 months.

  • Benefits of TVS-2M fuel 

  • TVS-2M fuel assemblies have several advantages that make them more reliable and cost-effective.

  • The fuel combinations in the reactor core maintain their geometry.

  • one TVS-2 M assembly contains 7.6% more fuel material than that of UTVS. 

  • Its main feature is the new generation anti-debris filter ADF-2, which protects the bundles from damage caused by debris (small objects in the reactor core).

  • Operating in a longer fuel cycle also increases the economic efficiency of a plant.

  • Kudankulam Nuclear Power Plant (KNPP)

  • located -  coastal Tamil Nadu

  • built by - India in joint-collaboration with Russia.

  • Construction on the plant began on 31 March 2002

  • it is India’s Critical Information Infrastructure

  • It has an installed capacity of 6,000 MW of electricity
