REACTOR SHIFT

CANDUsim · ARCADE

You have the keys to a 900-megawatt CANDU reactor for one twelve-hour shift. Keep the city lit. Keep the core balanced. Do not let it poison out.

⚡
MATCH DEMANDThe city asks for power. Hit POWER ± to match it. Matching earns points — keep it up and your combo climbs.
⚖️
KEEP THE ZONES GREENFuel burns and the zones drift down. REFUEL lifts them, POISON pushes them down. Out of band = no points.
🚨
HANDLE WHATEVER HAPPENSGrid faults, runaway power, breakdowns. ACK alarms fast. If power runs away, TRIP it — then race the xenon to restart.
☢️
DON'T MELT ITCORE HEAT climbs if you overpower or lose the boilers — AUX FEED keeps the heat sink. SDS1 BYPASS switches off the trip protection; PULL RODS adds reactivity by hand. Do both and you will find out what a meltdown looks like.

About the project 3D version

Underneath the buttons is a real CANDU reactor model — xenon, shutoff rods, liquid zones, stepbacks. It behaves like the real thing, just 120× faster.
