ItemDebug still lack this code.
Code
if (var13 instanceof IReactorChamber)
{
IReactorChamber TEST =(IReactorChamber)var13;
IReactor var24 = TEST.getReactor();
IC2.platform.messagePlayer(var2, "Reactor: Heat=" + var24.getHeat() + " MaxHeat=" + var24.getMaxHeat() + " HEM=" + var24.getHeatEffectModifier() + " Output=" + var24.getOutput());
}
For not devs, this code allow to measure reactor stats by it's chambers, currently you cant get any data from chamber.
