Rajasthan's Revamped Nuclear Power Plant Rejoins Grid

A 220 MW nuclear power plant in Rawatbhata, Rajasthan, has been reconnected to the grid following a significant renovation and modernization effort. The Rajasthan Atomic Power Station Unit 3, operational since 2000, underwent major upgrades including coolant and feeder replacements, positioning India competitively in global nuclear services.

A 220 MW nuclear power plant at Rawatbhata in Rajasthan has been reconnected to the grid after its lifespan was extended by around 30 years through comprehensive renovation and modernization, according to the plant operator.

Unit 3 of the Rajasthan Atomic Power Station (RAPS-3), which started commercial operations on June 1, 2000, underwent a significant overhaul starting October 27, 2022. The unit was reconnected to the grid on July 24 this year.

The renovation included Enmasse Coolant Channel Replacement (EMCCR) and Enmasse Feeder Replacement (EMFR), as well as other critical upgrades, as stated by the Nuclear Power Corporation of India Limited (NPCIL). Remarkably, these activities were completed using indigenous precision technologies, ensuring safety and efficiency.

NPCIL highlighted that R&M activities were executed in record time for Indian reactors and within budget, despite a rise in prices for essential components. The per MW cost of the renovation was significantly lower than international standards for Pressurised Heavy Water Reactors (PHWRs).

With this achievement, India has established a competitive edge in safely and precisely performing such in-core tasks at a lower cost, potentially opening avenues for exporting these specialized services globally.
