Will be adding gregtech reactors shortly, pasting notes here so I don't lose them and to have them screened.
Thorium positivee hybrid reactor, 8 extra per Thorium cycle. 484 EU/t.
Hybrid Efficiency 12.9 +8t
Thorium Neutral hybrid reactor, isotope arrangement by BrickedKeyboard, cooling system by Requia. 367 EU/t
Hybrid efficiency 14.68+0t
Thorium negative hybrid reactor, takes 4 extra thorium per thorium cycle, 420 EU/t. This one is all BrickedKeyboard. (combining two of this reactor with one of the first has neutral thorium use and beats the efficiency of a thorium neutral reactor).
Hybrid efficiency: 16.8 -4t
Beginner thorium reactor. 32 EU/t, easily doubled.
Thorium efficiency: 4
2 chamber compact tiling of the arrangement above, 128 EU/t
Thorium Efficiency 4
Another zero chamber, more power (72 EU/t), less efficienct.
Thorium efficiency 3
Single chamber high efficiency thorium, 80 EU/t. Easily doubled in a bigger reactor.
Thorium Efficiency 5
