Which consequence results when excessive alpha decay products accumulate within fusion reactor walls?

💡 Explanation

Helium bubble production results in spallation because alpha particles (Helium nuclei) get trapped and coalesce when generated inside the wall material, causing internal stresses. This leads to surface sputtering and material loss, therefore spallation dominates rather than alternative embrittlement mechanisms.
