Why is this in the news?

The Department of Atomic Energy (DAE) has recently submitted a detailed status report to Parliament on the progress of ongoing nuclear power projects in India, highlighting delays, cost overruns, and corrective measures. This report underscores the strategic importance of nuclear energy in India’s energy mix while also revealing systemic challenges in project execution, including geopolitical disruptions, supply chain bottlenecks, and regulatory hurdles.

Background

• India’s nuclear power programme is a key component of its energy security strategy, aiming to diversify the energy mix and reduce dependence on fossil fuels.
• The programme is governed by the Atomic Energy Act, 1962, and implemented by the Department of Atomic Energy (DAE) through its public sector undertaking, the Nuclear Power Corporation of India Limited (NPCIL).
• India operates 23 nuclear power reactors with a total installed capacity of 7,480 MW, contributing approximately 3.1% to the national electricity grid.
• The indigenous Pressurised Heavy Water Reactor (PHWR) technology forms the backbone of India’s nuclear fleet, while Light Water Reactor (LWR) projects are being developed with international cooperation, primarily with the Russian Federation.
• The Fukushima Daiichi nuclear accident (2011) led to a global reassessment of nuclear safety standards, prompting India to implement enhanced safety measures in its nuclear projects.
• The COVID-19 pandemic (2020–2022) disrupted supply chains, labour availability, and project timelines across the nuclear sector.

What are India’s Ongoing Nuclear Power Projects?

• The projects utilise two primary reactor technologies: Pressurised Heavy Water Reactors (PHWRs) and Light Water Reactors (LWRs). PHWRs (700 MW each) are indigenously developed, while LWRs (1,000 MW each) are being set up with Russian collaboration at Kudankulam (KKNPP units 3–6).
• Key PHWR projects include: (1) RAPP-7 & 8 (Rajasthan, 700 MW each), (2) KAIGA-5 & 6 (Karnataka, 700 MW each), and (3) PFBR (Kalpakkam, Tamil Nadu, 500 MW, a Fast Breeder Reactor prototype).
• Light Water Reactor projects under construction at Kudankulam (KKNPP units 3–6) are being implemented with Russian technical and financial assistance under the Indo-Russian Inter-Governmental Agreement (IGA) on cooperation in the peaceful uses of atomic energy.
• The Gorakhpur Haryana Anu Vidyut Pariyojana (GHAVP) units 1 & 2 (700 MW each) in Haryana face unique challenges due to difficult soil conditions and require extensive site preparation.
• The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam is India’s first indigenously designed and constructed FBR, a critical step towards achieving a closed nuclear fuel cycle and enhancing fuel efficiency.
• The Department of Atomic Energy (DAE) and NPCIL have adopted a multi-pronged approach to address delays, including periodic project reviews, vendor engagement, bulk procurement of long-lead items, and delegation of powers to field officers for faster decision-making.
• The financial outlay for these projects has seen significant revisions due to inflation, supply chain disruptions, and enhanced safety measures, with total approved costs exceeding ₹20,000 crore for most units.
