The ITER project, in which India is a partner, aims to demonstrate net energy gain from nuclear fusion using which fuel cycle?
- Deuterium-Deuterium
- Deuterium-Tritium
- Proton-Boron
- Helium-3-Deuterium
Answer: Deuterium-Tritium
ITER (France) uses D-T fusion: D + T → He + n + 17.6 MeV. Requires plasma at 150 million °C confined by magnetic fields (tokamak). Success would pave way for commercial fusion power. India contributes critical components. [[DST Reports, NCERT Physics Class 12]]
