Thermo-mechanical coupled analysis and probabilistic safety evaluation of the prestressed concrete containment vessel under accident pressure

Key Points

• The assessment shows that accident pressure significantly affects the containment vessel's structural stability.
• Key evidence includes a probabilistic safety evaluation highlighting a 20% increase in risk under specific stress conditions.
• Thermo-mechanical coupled analysis assesses vessel performance in simulated accident scenarios using advanced modeling techniques.
• These findings may enable improved design standards in concrete containment structures for nuclear facilities.
