holtec.com l smrllc.com l Page 4 SMR-300 Design Evolution Light water PWR Power output: 1050 MWt, ~300MWe Design lifetime: 80 years Forced circulation (2 RCPs, 2 hot legs, and 2 cold legs)
Once-through steam generator Traditional PWR fuel system
holtec.com l smrllc.com l Page 5 SMR-300 Design Evolution Upgrades:
Increased power output: 160 MWe ~300MWe Removed FOAK forging connecting RPV and SG Natural circulation Forced circulation (Maintain natural circulation for DHR)
Reduced reactor length; reduced steam generator volume Increased integral pressurizer volume for operational control
