Summary

In this lecture, Shri S A Bhardwaj, former chairman of the Atomic Energy Regulatory Board, provides a comprehensive overview of the nuclear fuel cycle, focusing on the Indian context. He explains that natural uranium consists of 0.7% fissile U-235 and 99.3% fertile U-238, which can be converted to plutonium. Thorium is mentioned as a future resource but not covered in detail. The talk covers mining, milling, conversion to UF6, enrichment via gas centrifuges, and fuel fabrication, including pellet production and assembly design for PHWRs, PWRs, and BWRs. He emphasizes the safety challenges posed by fission products, which are radioactive and generate decay heat for extended periods, requiring continuous cooling and shielding. He discusses the importance of quality in fuel manufacturing and the regulatory oversight. He also highlights incidents like Three Mile Island, Fukushima, and Chernobyl to illustrate the consequences of inadequate cooling or overpower. The lecture concludes by noting that the Indian government has opened certain parts of the fuel cycle to private industry, including fuel fabrication and reactor operation, while enrichment remains restricted.
