Bummer that it doesn't specify which application of nuclear power, but seeing as I'm forced to guess, I'd surmise they're using RTG.

Radioisotope Thermoelectric Generator

The spicy rocks get hot and the differential between the hot bit and the cold exterior (and titan is VERY COLD INDEED) "pushes" electrons, to put it as simply as possible.

IF SO, it's pretty normal for the most part; we've been using RTGs for generations. A decent mostly solid-state power supply that, while rather thermally wasteful it's very reliable.

(there are ways to get more electrical power from the same amount of heat but they're more complicated and can break more easily)
