What must the Tritium Breeding Ratio (TBR) be greater than for a plant to achieve self-sufficiency?

Answer

Greater than one

For the fusion power plant to be self-sufficient in its fuel supply, the tritium breeding ratio (TBR) must exceed one, meaning it must produce more tritium than the fusion reaction consumes.
