Gates' TerraPower Secures US SMR Permit

🔑 Enhanced Key Takeaways

• •The SMR is TerraPower's Natrium reactor, located in Kemmerer, Wyoming, using a novel liquid sodium coolant design instead of water.[2][4]
• •NRC completed the safety review in 18 months, accelerated by a 2024 congressional law, marking the first non-light-water reactor construction permit in over 40 years.[2][4]
• •The project, costing up to $4 billion, is funded partly by DOE's Advanced Reactor Demonstration Program and targets operation by 2030-2031.[1][4]
• •Recent partnerships include a deal with Meta for up to eight reactors starting 2032 and investment from Korea Hydro & Nuclear Power.[3]

🛠️ Technical Deep Dive

• •Natrium reactor is a 345 MW sodium-cooled fast reactor paired with a molten salt-based energy storage system.
• •Storage boosts output to 500 MW for limited periods, enabling integration with renewables and powering ~400,000 homes at peak.
• •Uses molten sodium as coolant, differing from traditional light-water reactors; produces less nuclear waste per TerraPower claims.[2][4][5]
