Definition
安全壳 is a technical noun meaning 'containment vessel' — the thick concrete and steel structure that encloses a nuclear reactor to prevent radiation leaks. You'll encounter it in engineering, nuclear safety, and industrial contexts. Because it's a compound noun (安全 'safety' + 壳 'shell/hull'), the two characters stay together and don't split.
