← ScienceWhich risk increases unexpectedly in pulsed fusion reactors when tritium decays?
A)Neutron flux within the blanket
B)Helium-3 buildup within coolant✓
C)Decreased plasma confinement time
D)Bremsstrahlung radiation from impurities
💡 Explanation
Helium-3 buildup rises because tritium beta decay transmutes tritium into helium-3 nuclei; therefore, heat transfer inefficiencies are increased in the coolant, rather than plasma confinement issues or neutron flux alteration, because helium affects thermal properties
