...(you can just set an Project Red logics to turn reactor on/off depend on base main power storage)....
In fact i'm doing this with RS latch and some street magic.
I’ve got thousands of thorium crushed ore stored as a byproduct of drilling for other things.
I thought that way too before realised that depleted thorium made from regular thorium fuel rods in reactor in 50000 seconds. I got 2 reactors now stuffed only with 26 singlecell thorium each and heat vents and in two weeks did not got an 1/3 of lutetium amount needed (actually don't need it now, just want to get it and forget for later)
The turbine is still “enabled,” so it will re-start if you give if steam again, but does it spin down and require spin up when you feed it steam again?
Turbine Enabled means it will start spinning (generate EU and grow speed) when new steam (whatever amount) will be added into input hatch. It also had 10 sec spindown effect, in which i think it can spin up again when steam applied. After full stop there will be full spin up again. Spinup is just 5 times longer than spindown.
