This is a variant of Modular Nuclear Plant [160 MW to 1.4 GW] using belts to provide fuel cells for use before requester chests are available. Later it can still be expanded to use all 10 cores with requester chests, for a total of 1.4GW just like the original.
Max output is 480MW from 4 reactors.
Control circuit and alerts:
- A steam reserve is used to monitor usage.
- When steam gets to half (100k) or less the reactors will be started (if not running).
- When steam gets to 30k or less, a siren will sound and the plant will disconnect from the grid until steam is back above half.
- If the reactor does not start on the start signal, an alarm will sound.
- If steam reserves are adequate when the reactors finish a cycle, "eco" mode will engage, turbines will run off steam reserves until half depleted.
Lights for monitoring status:
- Green: Reactor running
- Blue: Eco Mode
- Purple: Reactor startup (Should be only momentary)
- Yellow: Steam reserves below half
- Red: Steam reserves below 15%
The reactor closest to the circuit control is the master reactor, this is used to determine if the reactors are running or not, it is assumed that all other reactors are in sync. This should remain true as long as fuel supply is adequate.
How to use:
The 2 big electric poles running out the centre along the road should be isolated from plant's own power network so that it can disconnect itself if power levels run low. This ensures that the plant will always be able to retain power for the vital function of feeding the reactors and running control circuitry.
For the initial startup you will need to bridge these 2 grids until the red light goes off. I suggest not putting in the alarms until the plant is fully online ;)
When adding reactors, connect the feeder inserters to the green circuit network that runs around the medium poles. Copy the settings of another feeder inserter using shift + right-click, shift + left-click.
Replace the belt and wooden chests with requester chests as soon as you have the research, filling in all the heatpipes as per the original blueprint above, his book contains useful sections for modular expansion.
