Strategic Products
| Product | Technology | Power | Status |
|---|---|---|---|
| NuRTG | Radioisotope Thermoelectric Generator | W to kW | Development with this funding |
| NuThor | Thorium Molten Salt Reactor | 5 MW | Future opportunity |
NuRTG: Radioisotope Thermoelectric Generator
Product Description
NuRTG is a radioisotope thermoelectric generator designed to provide medium to high power output for applications where nuclear voltaic batteries cannot deliver sufficient power.
| Specification | Details |
|---|---|
| Full Name | NuBatt Radioisotope Thermoelectric Generator |
| Technology | Thermoelectric conversion of radioisotope decay heat |
| Power Output | Watts to kilowatts |
| Operational Life | 10+ years continuous operation |
| Form Factor | Modular, scalable |
Technology Principle
Unlike nuclear voltaic devices that convert radiation directly to electricity, RTGs convert the heat generated by radioactive decay into electricity using thermoelectric materials. When radioisotopes decay, they release energy as heat. This heat is captured by thermoelectric converters (based on the Seebeck effect) to generate electrical current.
Key Innovation
NuRTG differentiates from traditional RTG programmes through:
