RUSSIA OFFERS NEW N-FUEL SOLUTIONS FOR COUNTRY’S ATOMIC REACTORS
NEW DELHI: Russia has offered new technologies and solutions for the nuclear fuel cycle of India’s atomic power plants that are aimed at enhancing the efficiency of the reactors at the Kudankulam power project.
The new technologies were unveiled by Alexander Ugryumov, the senior vice-president for research and development at TVEL, the fuel division of Russia’s state-run Rosatom corporation, while participating at a conference in Hyderabad. These solutions can enhance the efficiency of the existing VVER1000 reactors at Kudankulam and the ones under construction, Rosatom said on Tuesday.
Two Russian-designed 1,000 MW pressurised water reactors are currently operational at the Kundankulam power project and four more reactors are being built at the site in Tamil Nadu. Russia has continued supplying crucial components for the project despite uncertainties created by the conflict in Ukraine.
Among the new solutions and technologies are new models of nuclear fuel, solutions for higher uranium enrichment and technologies for a closed nuclear fuel cycle, Rosatom said. These technologies offer the potential to make the Kudankulam power plant’s operations more efficient over several decades.
Ugryumov said the introduction of nuclear fuel with more than 5% enrichment will enable the VVER-1000 reactors to operate for longer 24-month fuel cycles and have a significant economic impact on the unit’s lifecycle. An extended fuel cycle also means the power plant needs to stop reactors for refuelling less frequently, procure fewer fresh fuel assemblies, and offload less irradiated fuel bundles since the handling of spent fuel also requires expenses.
