Which material constraint limits sustained Lawson criterion fusion?

💡 Explanation

Neutron flux from deuterium-tritium fusion causes neutron-induced material embrittlement because high-energy neutrons displace atoms from the crystal lattice. This leads to component failure by crack propagation, therefore embrittlement, rather than other thermal or chemical changes, limits reactor lifetime.
