NUCLEAR POWER

A nuclear power plant is a facility that generates electricity using the heat produced from controlled nuclear fission. In India, nuclear power stations are operated by Nuclear Power Corporation of India Limited (NPCIL). Key features of a nuclear power plant

NPCIL operates several major nuclear stations including Tarapur, Kakrapar, Kudankulam, Kalpakkam, Narora, Kaiga, and Rawatbhata.

Varta (Vb series) batteries are industrial-grade lead–acid batteries specifically designed for high-reliability backup power applications. In NPCIL nuclear power stations, these batteries play a critical safety role


Why Varta Vb Batteries Preferred in Nuclear Plants

  • Designed for high reliability and long service life
  • Excellent performance in critical standby applications
  • Proven quality for nuclear-grade requirements
  • Robust construction with:
    • Low internal resistance
    • High discharge capability
    • Stable float voltage behavior
  • High resilience to temperature variations and seismic requirements
