Operator Tutorial / Event Log
Emergency Actions
- Brownout: raise turbine load, slowly withdraw rods, use battery, or shed load.
- Overload: lower turbine load and keep output close to demand.
- High temp: warning begins around 700°C. Lower rods, raise pumps, and add coolant.
- High pressure: vent pressure, lower rods, increase feedwater carefully.
- Low coolant: add coolant and raise pumps. Watch pressure afterward.
- Fuel damage: above ~1,100°C. Hydrogen risk rises above ~1,200°C. Core melt begins near ~2,500°C and full fuel melting near ~2,800°C.
- Meltdown danger: pumps 100%, rods down, add coolant, vent pressure, then SCRAM.
- Demo Mode: automatically creates warnings, sounds alarms, then performs corrective actions.
Start the game. Keep output near demand.
