plutonium-238

[plü′tō·nē·əm ¦tü‚thər·dē′āt]
(nuclear physics)
The first synthetic isotope made of plutonium; similar chemically to uranium and neptunium; atomic number 94; formed by bombardment of uranium with deuterons.

The rover, which has the main purpose of looking for habitable areas around the Red Planet, will be able to produce about 110 watts of electrical power via a chemical process that relies on the natural decay of plutonium-238 into uranium-234. 
Because of how far the planets are from the sun, any craft sent to them would have to rely on internal power instead of solar panels, meaning the craft would use plutonium-238 atomic batteries.Read more at: https://ascienceenthusiast.com/nasa-plans-probe-uranus-search-gas/
In 1972, about 19,000 gallons (71,920 liters) of highly radioactive sodium bearing waste that involved the tritium, strontium-90, cesium-137 and plutonium-238 spilled during a failed underground transfer at the Idaho Nuclear Technology and Engineering Center's tank farm.
RTGs convert heat generated by decaying plutonium-238 (Pu-238) fuel into electricity.
Oak Ridge did indeed make a breakthrough at the end of 2015, when they announced a new process to manufacture Plutonium-238, a vital energy source for long space missions.
The production of 50 grams of plutonium-238 -roughly the mass of a golf ball -- marks the first demonstration in the United States since the Savannah River Plant in South Carolina ceased production in the late 1980s.
OAK RIDGE, Tenn., Rabi'I 12, 1437, December 23, 2015, SPA -- For the first time in 30 years, federal scientists have produced plutonium-238, , according to UPI.
In order to survive the harsh nighttime conditions on the Moon, when the temperature can fall from daytime highs of 123 degrees celsius to as low as minus 153 degrees, Luna-Globe is fitted with a radioisotope thermoelectric generator, which provides power by converting the heat generated by the decay of the plutonium-238 isotope into electricity.
Plutonium-238 (Pu-238) Programs: Pu-238 is the heat source for
The ESA program indicates americium-241, which is found in decaying plutonium, produced from reprocessing nuclear fuel, could replace plutonium-238 in batteries used in space probes, such as NASA's "Curiosity" Mars lander.
To reach Mars, the rover Curiosity relied on plutonium from a Soviet-era nuclear weapons plant, reports Geoffrey Brumfiel for Slate: "plutonium-238 is really a byproduct of the process for making another kind of plutonium, known as isotope 239....It takes just a couple of pounds of the stuff to make a bomb as powerful as many kilotons of TNT." NASA relies on nuclear fuel for space missions that won't return to Earth.
