Pu-238 is ideal for deep-space travel because of its long half-life of nearly 88 years, but it has been in short supply. Previously, the U.S. stockpile consisted primarily of Pu-238 produced at the Savannah River nuclear plant in the late 1980s, which has since been decaying away.

For example, each atom of the Pu-238 isotope contains 144 neutrons, while each atom of the Pu-239 isotope contains 145 of these neutral particles. Radioactive Pu-238 product into the form used for power sources has been identified to reduce the cost of the final product. In short, the concept appears to be viable, can produce the amount of Pu-238 needed to support the NASA missions, can be available within a few years, … Why Pu-238 Specifically? RTGs use Pu-238. The isotope's half-life of 88 years and stability at high temperatures make it ideal for the conditions under which an RTG must operate.

Previously, the U.S. stockpile consisted primarily of Pu-238 produced at the Savannah River nuclear plant in the late 1980s, which has since been decaying away. But U.S. production of Pu-238 ended more than 30 years ago.

238 Pu and 239+240 Pu isotopes were measured in alpha spectrometer and 241 Pu results were calculated indirectly by activity measurements of 241 Am isotope increase from β-emitting 241 Pu in 16−18 years after Chernobyl accident. The {sup 238}Pu isotope is an excellent heat source and is currently used in generating electricity for deep-space applications. To produce {sup 238}Pu, special neptunium target assemblies would be irradiated for {approximately}2 yr in the Fast Flux Test Facility (FFTF) operated by Westinghouse Handford Company.
