The Gorakhpur Nuclear Power Project (GHAVP) in Haryana, comprising four units of 700 MW each, is progressing steadily with the first two units GHAVP-1&2, expected to be completed by 2031-32. The project has faced delays primarily due to unforeseen soil conditions encountered during the early stages of construction.
The project, situated in Fatehabad district, includes two phases of twin units each (2×700 MW), with GHAVP-1 & 2 currently under construction. Administrative approval and financial sanction for the first phase were granted in February 2014, and excavation activities began in 2018. However, the soil-based site presented significant challenges, including localised weak zones that were not initially apparent.
To address these issues, the Nuclear Power Corporation of India Ltd (NPCIL) adopted a technique of ground improvement using compacted soil-cement mix. Foundation piles were constructed and qualified, but further geotechnical investigations revealed unexpected weak zones in the soil strata. This prompted the engagement of a reputed consultant, who conducted comprehensive studies and submitted remediation recommendations. These are currently under review by the regulatory authority.
Despite delays in the construction of the main nuclear island, progress has been made on several fronts. Major equipment and engineering, procurement, and construction (EPC) packages, including Main Plant Civil Works, Nuclear Piping, Turbine Island, and Induced Draft Cooling Towers (IDCT), have been awarded and are under execution. Some critical long-lead equipment has already been received at the site.
Efforts to streamline the project include close monitoring of progress, proactive issue resolution, frequent coordination with vendors and contractors, and re-sequencing of activities to maintain momentum. Construction in peripheral buildings and structures continues, with full-scale work on the nuclear island set to commence following completion of site-specific ground improvement measures and regulatory approvals.
Once operational, the Gorakhpur Nuclear Power Project will significantly enhance the country’s nuclear power capacity and contribute to India’s goal of cleaner and more sustainable energy.
