Requirement of Uranium for Nuclear Reactors
The approximate requirements of uranium (Annual requirement at 85% Capacity Factor) for Pressurized Heavy Water Reactors (PHWRs) are given below:

Unit Capacity (MW) | UO2 (tons) |
220 | 45 |
540 | 100 |
700 | 125 |
The approximate requirements of uranium (Annual requirement at 85% Capacity Factor) for Light Water Reactors (LWRs) are as given below:
Unit Capacity (MW) | UO2 (tons) |
160 | 6 (at 85% CF) |
1000 | 25 (at 90% CF) |
Uranium fuel requirement for the reactors which are not covered under the International Atomic Energy Agency (IAEA) safeguards is adequately met by Uranium Corporation of India Limited (UCIL), a Public Sector Enterprise under the Department of Atomic Energy (DAE).
