Help with Interstellar radiators

[nhnifong]

I'm trying to use the KSP interstellar version of the nerva, "Solid NTR Nerva" and it seems like there's just nothing I can do to radiate the heat enough to prevent it from overheating parts of my ship. Specifically, there is a battery that cannot tolerate more than 850 degrees.

Even with an enormous amount of radiators it still overhearts. It seems to me like radiators just don't radiate stock heat, but only radiate "MW". But is wierd because there are two radiator modules on every part "Radiator" and "Active Radiator". Surely if there were two kinds of heat and two kinds of radiators, one of them would radiate stock heat right?

Another wierd thing is that the KSP interstellar wiki says that when thermal rockets are running they will dump all heat out the back with the propellant, but that clearly does not seem to be the case. The heat is negligible whenever this rocket is off, and when it is trusting, the ship overheats until that sensitive part explodes in 3 mintues regardless of radiators.

I'm running KSP 1.0.4, Interstellar, and Deadly Reentry and about 1000 other mods.

Why a so old version of KSP? Btw, try to remove DRE, usually it cause issue with the Interstellar engines.

The last few versions have had too many bugs.

I'm not uninstalling DRE. I've just dealt with this by disabling heat unless I'm re-entering, but I would like to deal with it another way if a balanced game mechanic could be found.
