Heat leaves the reactor vault in a clean intermediate loop. A supercritical carbon dioxide turbine turns it into about 10 megawatts of electricity. Fans reject the waste heat, so the plant needs no cooling water.
Insulated pipes carry the clean intermediate fluid from the IHX to the power conversion unit and back. The loop keeps radioactive sodium inside the reactor vault.
| Pipes | 2 hot legs, 2 cold legs |
|---|---|
| Hot leg | ≈ 520 °C |
| Cold leg | ≈ 370 °C |
| Insulation | Mineral wool with steel jacket |
The PCU turns heat into electricity. Hot intermediate fluid heats a working gas that spins a turbine and a generator.
| Cycle | Supercritical CO₂ Brayton |
|---|---|
| Net output | ≈ 10 MWe |
| Efficiency | ≈ 35–40% |
| Footprint | One truck-transportable skid |
Fans blow air across finned tubes to reject the waste heat of the power cycle. Dry cooling means the plant needs no cooling water.
| Type | Forced-draft dry cooler |
|---|---|
| Heat rejected | ≈ 20 MWt |
| Fans | 6 × 3 m diameter |
| Water use | None |
