Union MoS Jitendra Singh speaks in the Lok Sabha during the Monsoon session of Parliament NEW DELHI: A key objective of the govt under the Nuclear Energy Mission is to develop and operationalise at least five indigenous small modular reactors by 2033, minister for department of atomic energy Jitendra Singh said in a written reply in the Lok Sabha on Wednesday.Bhabha Atomic Research Centre (BARC) is undertaking the design and development of indigenous SMR technologies, including the 220 MWe Bharat Small Modular Reactor (BSMR-200) and 55 MWe SMR-55 for power generation. BARC is also developing a high temperature gas cooled reactor (HTGCR) of up to 5 MW capacity, which can be coupled with a suitable thermochemical cycle for hydrogen production.Singh said India is steadily strengthening its indigenous nuclear energy ecosystem with a focus on advanced reactor technologies, SMRs, domestic manufacturing capabilities, private-sector participation and long-term utilisation of the country’s abundant thorium resources. The govt has adopted a two-pronged approach to accelerate nuclear capacity addition. This includes deployment of large indigenous reactors such as 700 MWe pressurised heavy water reactors (PHWRs) and advanced reactor designs at greenfield sites, alongside development and deployment of SMRs at brownfield locations, including retiring fossil-fuel-based power plants, captive plants for energy-intensive industries and off-grid applications in remote areas.The minister also highlighted continuing work of the Indira Gandhi Centre for Atomic Research (IGCAR) in advancing the second stage of India’s nuclear power programme. IGCAR is pursuing multidisciplinary scientific research and advanced engineering development for sodium cooled fast breeder reactors and associated closed fuel-cycle facilities, technologies that remain a cornerstone of India’s long-term nuclear strategy.Join conversationView All Comments →Share your thoughts in the commentsInsightfulAgreeDisagreeSkepticalConcerningPromisingWorth ReadingBig DevelopmentPost CommentBe respectful · TOI community guidelines On thorium, Singh said India is pursuing its three-stage nuclear power programme, based on a closed fuel cycle, to optimise utilisation of its uranium resources and progressively harness its abundant thorium reserves.
