Gen4 Module (G4M)
| Designer: | GEN4 ENERGY |
|
| Reactor Power: | 70 MWt |
|
| Electrical Output: | 25 MWe |
|
| Outlet Conditions: | 500°C |
|
| Coolant: | Lead-bismuth eutectic, primary and secondary loops |
|
| Fuel Design: | Stainless steel clad uranium nitride |
|
| Refueling: | Entire reactor module replaced every 10 years |
|
| Licensing Plan: | Combined License (prototypical design) and/or Design Certification |
|
| Planned Submittal: | Undisclosed |
|
| Design Information: | The G4M is sealed at the factory, sited underground, and eventually returned to the factory for waste and fuel disposition after a useful life of ten years. The principal materials in the core are uranium nitride (UN) fuel, stainless steel as the structural material, lead-bismuth eutectic (LBE) as the coolant, quartz as the radial reflector, B4C rods and pellets for in-core reactivity control and shutdown. The LBE permits ambient pressure operation of core, eliminating pressure vessel requirements. |
|
| Status/Other Info: | The outer diameter of the entire reactor system, including the outer reflector and coolant downcomer, is limited to 1.5 m to be able to seal the reactor vessel system at the fabrication facility and transport it to the site in a conventional nuclear fuel shipping cask. The total mass of the reactor vessel with fuel and coolant is <20 metric tons. |
