Executive Summary
This report provides a status update on nuclear power projects currently under construction in India as of August 2026. It details the capacity, revised commissioning schedules, and financial allocations for various indigenous and foreign-cooperation reactors. The document outlines the reasons for project delays and the corrective measures being implemented to ensure the eventual addition of 8,000 MW to the national grid.
Key Points / Main Content
Project Status and Capacity
Indigenous Pressurised Heavy Water Reactors (IPHWR): RAPP-7 (Rawatbhata) commenced commercial operation on April 15, 2026. RAPP-8 is in advanced commissioning, expected by late 2026.
Long-term Projects: GHAVP-1 & 2 (Gorakhpur) are expected to take approximately six years from the "First Pour of Concrete." KAIGA-5 & 6 have revised commissioning dates of June 2031 and June 2032, respectively.
Fast Breeder Technology: The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam has a revised commissioning target of March 2027.
Foreign Cooperation (LWR): Kudankulam (KKNPP) units 3 through 6 are scheduled for completion between June 2027 and March 2030.
Factors Influencing Delays
Technical and Environmental: Extensive design changes following the Fukushima incident and difficult soil conditions at the GHAVP site.
Supply Chain and Geopolitical: Delays in critical equipment supply from the Russian Federation and impacts from the Russia-Ukraine and USA/Israel-Iran conflicts.
Logistical: Disruptions caused by the Covid-19 pandemic, including contractor financial constraints and shortages of skilled manpower.
Corrective Measures and Implementation
Monitoring: Periodic reviews at multiple levels within NPCIL and DAE, alongside the constitution of a Board sub-committee for project monitoring.
Efficiency Drives: Adoption of "fleet mode" for reactor implementation and bulk ordering of long-delivery equipment to ensure timely supply.
Administrative Actions: Higher delegation of powers to NPCIL executives and frequent vendor/contractor meetings to resolve site-specific constraints.
Financial Overview
Detailed annexures track equity sanctioned, released, and utilized from 2021 to 2024.
Total equity utilized across major projects (excluding PFBR) reached Rs. 1,990 crore in the 2023-24 period.
Impact Analysis
National Grid and Energy SectorImpact
The grid will see a cumulative capacity addition of 8,000 MW upon the progressive commissioning of these projects.
Action Required
Prepare for the integration of high-capacity nuclear power loads as projects like RAPP-8 and KKNPP-3 reach completion between 2026 and 2027.
NPCIL and Department of Atomic Energy (DAE)Impact
These bodies are under increased pressure to manage revised timelines and escalating costs (some of which are currently "under revision").
Action Required
Must conduct constant monitoring of project activities, identify constraints early, and execute mid-course corrections and re-sequencing of construction activities.
Contractors and VendorsImpact
Contractors are facing financial crunches and manpower shortages that have slowed execution at sites like GHAVP.
Action Required
Attend frequent coordination meetings with NPCIL/DAE to resolve cash flow problems and address skilled labor requirements.
Parliament and Government OversightImpact
Informed of the specific geopolitical and technical reasons for project setbacks and the status of sanctioned funds.
Action Required
Continue monitoring the utilization of sanctioned equity and the progress of the "fleet mode" implementation to ensure return on investment.
Key Entities Referenced
Department of Atomic Energy (DAE): The primary government department responsible for the oversight, policy implementation, and funding of nuclear power projects in India.
Nuclear Power Corporation of India Limited (NPCIL): The implementing agency responsible for project reviews, monitoring construction progress, and managing the execution of nuclear power plants.
Indigenous Pressurised Heavy Water Reactors (IPHWR): A major category of nuclear reactor projects, such as RAPP and KAIGA, being developed indigenously to enhance India's nuclear power capacity.
Light Water Reactors (LWR): Nuclear power projects implemented through foreign cooperation, specifically the Kudankulam Nuclear Power Project (KKNPP) series.
Dr. Jitendra Singh: The Minister of State who provided the detailed parliamentary response regarding the status, funding, and challenges of ongoing nuclear projects.

The year-wise details of the funds sanctioned, released and utilized for each project under
construction during the last five years are attached as Annexure.
The major reasons for delay in construction/ commissioning of projects in the recent past have
been due to extensive design changes following the Fukushima incident in Japan, delay in
supply of critical equipment, Covid-19 pandemic & related issues, delay in supplies from
Russian Federation (for KKNPP), delay in execution of works by contractors at site on account
of financial crunch / cash flow problems post Covid, difficult site soil conditions (at GHAVP),
shortage of skilled contractor manpower, and the impact due to ongoing Russia-Ukraine and
USA/ Israel-Iran geopolitical conflict.
To address the challenges, various measures are being implemented to ensure timely
completion of the projects. The measures include, periodic project reviews at multiple levels in
NPCIL & DAE, constant monitoring of progress of project activities, timely identification of
constraints & making necessary mid-course corrections, frequent meetings with vendors/
contractors to resolve various issues and re-sequencing of construction activities to the extent
possible, higher delegation of powers to various executives of NPCIL and constitution of
Board sub-committee for monitoring of projects. In addition to this, bulk ordering of longdelivery equipment has been adopted and many equipment are under manufacturing/
progressive delivery for various reactors being implemented in fleet mode to ensure timely
supply of long lead items for the projects.
Upon progressive commissioning of the projects currently under construction, a cumulative
capacity of 8000 MW would be added to the national grid.
