2x2 nuclear plant 471mw ish sustained production 488mw ish peak production. Variable output through sufficient storage tanks and a circuit that detects if new fuel cells should be added. Cold start capable, no player action required. seperate electrical grid and logistics networks. Redundant roboports, solar panels, accumulators and storage with 2x the amount of items to rebuild the plant. Logistical network bridge to input a specific amount of buildings, ammo, nuclear fuel, solid fuel, robots, repairpacks and output spend fuel cells. Controlled robot inserters to limit the amount of robots in system. 3 thick walls and zig zag gates to prevent tank and biter damage. Gun turrets supplied by requesters chests and fed by burner inserters. Always on radar to check on reactor during blackout. Alarms for low fuel cells in storage and low steam in storage tanks. Self repairing and rebuilding from major damage to most systems. Self building ish if roboports used for building are removed afterwards. All in all an expensive system designed to be as reliable as possible. Have fun throwing grenades at reactor cores.
