Background

Overview

India's ambitious nuclear energy program aims to enhance energy security, reduce carbon footprint, and achieve sustainable development goals. Understanding its global context, economic viability, and operational challenges is vital for policy formulation and international cooperation.

Nuclear power generation harnesses the energy released from nuclear fission to produce electricity. It is a low-carbon energy source that provides a stable, base-load power supply, crucial for energy security and meeting climate change targets, despite challenges related to waste management, safety, and high upfront investment costs.
