helium gas to cool its uranium-based fuel. That fuel would be packaged not in the conventional metal-clad rods, but in "pebbles"—spheres of graphite infused with countless ceramic kernels that contain the uranium. Like a giant gumball machine, the reactor would hold 220,000 pebbles, which would slowly descend through the core and, as their fuel was spent, would exit from a port at the bottom. Heated to 750°C, the helium would generate steam in a secondary circuit to produce electricity. In principle, the pebbles can't melt, eliminating the risk of a meltdown. ... The
Natrium and Xe-100 reactors would use fuel enriched to 20%, which would enable them to run longer on a batch of fuel and extract more energy from it.

Handling System, which performs continuous defueling and refueling of the reactor; loading fresh, recirculating used, and discharging spent fuel as required; and the Reactivity Control and Safe Shutdown System, which controls the outlet temperature of the reactor and provides a redundant shut down mechanism when required.

DOE will split the total cost of building each plant with private industry. Each project receives $ 80 million this year and could receive a total of between $ 400 million and $ 4 billion in funding over the next 5 to 7 years. ... In contrast, the Xe-100 design from X-Energy would use pressurized
