Oklo - Model EBR-II -Proven Technology
EBR-II was a fast reactor that produced about 20 MW of electric power and operated for 30 years. During its illustrious history, EBR-II and its on-site facilities recycled its used fuel, demonstrated inherent safety, achieved superior operating and maintenance characteristics to commercial light water reactors, and sold power to the grid.
The BOP-302R test demonstrated on EBR-II simulated a loss of heat sink without scram situation, where, starting from full power, the intermediate coolant pump was turned off while the control rods were prevented from inserting. The reactor temperature automatically stabilized within minutes.
The SHRT-45R test demonstrated on EBR-II, simulated a loss of flow without scram situation, where, starting from full power, the primary and intermediate coolant pumps were simultaneously turned off while the control rods were prevented from inserting. Again, the reactor rapidly and safely stabilized.
