I recently saw a presentation by some college students that investigated the feasibility of running ocean gliders on nuclear power. The proposal was to use a nice sized chunk of strontium 90 for a radioisotopic thermal generator. This would provide 45 watts electrical power for about 10 years. The interesting part was not the technical feasibility, but how they were going to make a case to the NRC to make such a use of radioisotopes legal. Apparently there is a precedent for this, some scientific ice monitoring equipment has used strontium 90 RTGs.
