It's @nyrath 's fault I think about cooling fins.

Interstellar ship - work in progress.

@thisnorthernboy @nyrath you need fewer fins, fins rotated 90 degrees, or fins divided into at least three rings. The surface of each fin should be pointed directly out to space, otherwise the fins are heating each other.
@SkipHuffman @nyrath Dammit. Good point. There will be another ring of fins, so I'll adjust when I add those. Thanks.

@thisnorthernboy @SkipHuffman @nyrath Pg 31 of this document has a recent nuclear electric concept design. (It also has chem prop).
