With a current global shortage of 238 Pu, 241 Am is being studied as RTG fuel by ESA and in 2019, UK's National Nuclear Laboratory announced the generation of usable electricity. An advantage over 238 Pu is that it is produced as nuclear waste and is nearly isotopically pure.

RTGs have been demonstrated to be highly reliable sources of $^{238}\text{Pu}$ is not good for either of those purposes. The only practical use of $^{238}\text{Pu}$ is in RTGs and their equivalent.

About Plutonium-238. A plutonium-238 fuel pellet, glowing with the heat it produces. Credit: U.S. Department of Energy. The fuel in an RPS is plutonium dioxide, which is a radioactive material that produces alpha particles. Alpha particles are a particular type of ionizing radiation that can be shielded by material as thin as a piece of paper.

Plutonium- 238 History. Among the different isotopes of plutonium, Pu-238 was the first to be on the NASA website, only about 20 have used an RTG or an RHU in the last five Plutonium-238) and the complex production process makes RPS a schedule 15 Feb 2010 An RTG has no moving parts and uses neither fission nor fusion processes.

Source: Los Alamos National Lab. 238 Pu costituisce solo l'uno o il due percento, ma può essere responsabile di gran parte del calore di decadimento a breve termine a causa della sua breve emivita rispetto ad altri isotopi di plutonio. Il plutonio di grado reattore non è utile per produrre 238 Pu per RTG perché sarebbe necessaria una separazione isotopica difficile .

To get a higher voltage many thermocouples are connected in series. If one thermocuple of the column or one of the connections fails, the whole column will fail. If there is only one column, the whole RTG will 2019-12-17 Trace amounts of Pu-238 were detected near Madagascar.
