The data hall is the load. It holds about 320 racks and draws about 8 megawatts. Batteries follow the load, UPS units ride through dips, standby generators cover outages, and rooftop coolers reject the heat.
The data hall holds the servers that use the reactor output. One microreactor carries roughly 8 MW of IT load plus cooling and losses.
| Footprint | ≈ 48 × 22 m |
|---|---|
| IT load | ≈ 8 MW |
| Racks | 320 at ≈ 25 kW each |
| Uptime target | Tier III, concurrently maintainable |
Servers sit in rows of racks with hot-aisle containment. Cold air enters the front of each rack and hot air leaves into a sealed aisle.
| Rows | 8 rows × 40 racks |
|---|---|
| Rack power | ≈ 25 kW, liquid-ready |
| Containment | Hot aisle, doors at each end |
| Distribution | Overhead busway, A and B feeds |
The electrical room receives the feed from the substation and conditions it. UPS units ride through short dips while the generators start.
| UPS | 2 × 5 MW, N+1 |
|---|---|
| Ride-through | ≈ 5 minutes at full load |
| Switchgear | 13.8 kV to 480 V |
| Distribution | PDUs feed the overhead busway |
Battery containers smooth the load the reactor sees. The reactor runs flat out, and the batteries absorb or supply the difference.
| Capacity | ≈ 10 MWh in 3 containers |
|---|---|
| Power | ≈ 5 MW |
| Chemistry | Lithium iron phosphate |
| Role | Load following and black start |
Standby generators cover the hall if the reactor or the line is out. With the reactor as prime power, they run only for tests.
| Units | 2 × 3 MW |
|---|---|
| Fuel | Diesel, 24 hours on site |
| Start time | < 10 s to full load |
| Duty | Standby, monthly test |
Rooftop coolers reject the heat the servers make. Fans pull air across coils, and the chilled loop returns to the hall.
| Heat rejected | ≈ 9 MW |
|---|---|
| Units | 6 rooftop dry coolers |
| Loop | Warm water, 30 °C supply |
| Water use | None, dry cooling |
