Summary0001457: Reactor endless heat
DescriptionIC2 Version: industrialcraft-2-2.2.650-experimental / Forge Version: forge-1.7.10-

Runaway heat calculation in liquid ic2 reactor
allows reactor to keep outputting heat without fuel
allows reactor to gain heat without fuel
Steps To Reproduce1 Create ic2 liquid nuke multiblock (my example 3 fluid ports, 1 hatch, 1 redstone port)

2 Preheat nuke with 1 quad until 0000008:0000010% - remove fuel

3 add fluid ejector to each port

4 create 3 sets of fluid heat exchangers feeding stirling generators - wire to mfsu

5 fill fluid heat exchangers with full heat conductors and a fluid ejector

6 make a ton of component heat vents and reactor heat exchangers, install in a checkerboard pattern (seemed to work with 1 row, 3+ rows best)

7 insert 5 ic2 liquid coolant

8 eventually core will stabilize with a cycling pattern of dmg on the heat exchangers

9 watch as heat keeps being dumped out (in my case 104hu constant) and msfu keeps filling

if you break the power cable once the buffers fill the core will gain heat upto around 4%. It might go higher but it slows right down.
