← ScienceWhich risk increases following tritium beta decay in fusion reactor breeding blankets?
A)Elevated helium-3 partial pressure✓
B)Structural embrittlement from alpha emission
C)Gamma ray induced superconductivity loss
D)Reduced neutron moderation factor
💡 Explanation
Helium-3 production accelerates because beta decay converts tritium to helium-3, increasing its partial pressure. Higher pressure stresses the system; therefore avoiding option B, because it is tritium decay that produces helium-3, rather than alpha emission.
