Parliamentary Panel Recommends MDO Entry in Uranium Mining; India's 3-Stage Nuclear Plan to Thorium

The Parliamentary Committee on Atomic Energy has recommended allowing Mine Developer-cum-Operator (MDO) participation in uranium mining under DAE oversight to meet India's growing fuel demand for indigenous PHWRs. India currently imports uranium from Kazakhstan, Russia, Uzbekistan, and Canada, and aims to expand nuclear capacity from 8.7 GWe to 100 GWe by 2047. The three-stage nuclear program aims to transition from uranium to thorium for long-term energy self-sufficiency.
