Explanation
It has been reported that India has discovered large uranium deposits at Rohil in Sikar district of Rajasthan, which is a significant development for the country's indigenous nuclear power program. The discovery of these uranium deposits is expected to reduce India's dependence on imported uranium and strengthen its energy security. The Rohil region has been identified as having substantial uranium deposits and the Department of Atomic Energy (DAE) has been conducting surveys and studies to assess the size and quality of the deposits. This discovery is a major step towards achieving India's goal of increasing the share of nuclear power in its energy mix and meeting the growing demand for electricity in the country.
