Planetary Resource Infrastructure_LeadAndTritium

For most fusion engines (and reactors) in FarFutureTechnologies: Introduces deuterium-tritium (D-T) fusion as an option. Given the scarcity of helium-3, I’ve opted to use tritium (produced in nuclear reactors) to sustain fusion operations on alien bases—ensuring players can still leverage fusion engines off-world. For balance, D-T fusion has lower specific impulse and requires lead (Pb) to shield against intense neutron radiation.
