Radioisotope Thermoelectric Generators (RTG), also called Radioisotope Power Systems (RPS) are power production systems most often used in long-distance space travel and remote areas on Earth.
As per the given combination of options RTGs can use Plutonium-238, which is a byproduct of weapons development.
Note: Many standard sources including NASA clearly mention that Plutonium-238 is not a weapon grade material.
