Reactor fuel rods become empty on relog. · Issue #192 · erogenousbeef/BigReactors · GitHub Costs me about 1000 Yellorium to relog :/
What I do is use the reactor to charge up some resonant cubes and fill up the reactor buffer than turn it off and then eject all the fuel.... If you use the super efficient 17x17x2 design... you can charge 3 cubes and the buffer using only 1-2 ingots.....
I use a ultra efficient design 27*25 so chunk borders will be crossed and even without turbine he spits out 160k RF ... and would run for hours, so theres no way to store that RF...
