This is what I mean.
Not hot in radioactivity. I mean hotter then a frying pan.
So yeah they would have to be depleted some or passive cooling wouldn't work in 85F without cooling. You said there is no cooling loop or working parts so whatever plutonium they have in there has to be depleted. That and all they are getting is 125 W. Its depleted or they put the most inefficient generator in space on it.
Thats all I'm saying.
Pu2o gets hot as hell. In space its no big deal. In 85F it can become and issue. There HAS to be something cooling it.
