• Drywell vessel, 190 m3
• Flow rate: 200 kg/s (sat. steam at 85 bar)
• Pressure suppression pool vessel, 350 m3
• RPV-simulator (GAP), 125 m3"

"In a BWR, the containment strategy is a bit different. A BWR's containment consists of a drywell where the reactor and associated cooling equipment is located and a wetwell. The drywell is much smaller than a PWR containment and plays a larger role. During the theoretical leakage design basis accident the reactor coolant flashes to steam in the drywell, pressurizing it rapidly. Vent pipes or tubes from the drywell direct the steam below the water level maintained in the wetwell (also known as a torus or suppression pool), condensing the steam, limiting the pressure ultimately reached. Both the drywell and the wetwell are enclosed by a secondary containment building, maintained at a slight sub-atmohttps://en.wikipedia.org/wiki/Containment_buildingspheric or negative pressure during normal operation and refueling operations."
