Step 1: Recall where India finds these minerals.
Uranium is mined mainly in Jharkhand (Jaduguda). Thorium comes from monazite sands along the coasts of Kerala and Tamil Nadu.
Step 2: Confirm both are nuclear fuels.
Both uranium and thorium are radioactive elements whose atoms can be split or converted to release nuclear energy, which is why both are counted as nuclear energy minerals.
Final Answer:
Uranium and thorium are the two minerals used in nuclear energy production.$\boxed{\text{Uranium, Thorium}}$
