In his message on X, Mr. Naidu described the development as a “proud moment for every Indian,” and said it marked a key step in the second stage of India’s nuclear programme. He noted that the milestone brought the country closer to harnessing its vast thorium reserves in the third stage and strengthened the path towards long-term energy security.
