Entities within a 7x7x7 cube (instead of a 3x3x3 cube) will get hurt from the radiation exposure. 'Golden CoreVents' are tricky to use. It efficiency is calculated as how many times each cell produces 5 EU/t, so a dual cell producing 20 EU/t has an efficiency of 2, and so produces 12 heat per cell, or 24 heat total. Nuclear craft reactor design I designed a reactor that can handle fuels with a base heat of up to 166. 2x glowstone coolerss A sample run script follows: Then chmod +x
