BWRX-300 Containment Design Background
- BWRX-300 containment is an underground subterranean steel or reinforced concrete primary containment vessel (PCV) or a combination of steel and reinforced concrete
- Containment heat is removed by Passive Containment Cooling System (PCCS)
- Combustible gas control is not required for design basis accidents (DBAs) because the BWRX-300 containment atmosphere is well mixed and the containment atmosphere is initially nitrogen-inerted 4
BWRX-300 Containment Performance NEDC-33911P provides design requirements, analytical methods, acceptance criteria, and regulatory bases for:
- Containment and the Passive Containment Cooling System (PCCS)
- Containment isolation valves (CIVs)
