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)
* Analytical methods evaluating containment performance
* Acceptance criteria for the BWRX-300 containment performance in accordance with the design requirements specified for the containment, PCCS, and CIVs 5
 
Overview of NRC Staff Review
* Piping and Valves Design Relevant to Containment Performance
* Containment Functional Design
* Containment Heat Removal Systems
* Secondary Containment Functional Design
* Containment Isolation System
* Combustible Gas Control in Containment
* Containment Leakage Testing
* Fracture Prevention of Containment Pressure Boundary 6}}
