The low-temperature heat capacity of (U 1−y Th y)O 2 and 238 Pu-doped UO 2 samples were determined using hybrid adiabatic relaxation calorimetry. Results of the investigated systems revealed the

It will outlast most customers; even after 20 years a Pu-238 based power source will produce 85% of its initial power output. RTGs provide electrical power using heat from the natural radioactive decay of plutonium-238, in the form of plutonium dioxide. The large difference in temperature between this hot fuel and the cold environment of space is applied across special solid-state metallic junctions called thermocouples, which generates an electrical current using no Plutonium was first made in December 1940 at Berkeley, California, by Glenn Seaborg, Arthur Wahl, Joseph Kennedy, and Edwin McMillan. They produced it by bombarding uranium-238 with deuterium nuclei (alpha particles). This first produced neptunium-238 with a half-life of two days, and this decayed by beta emission to form element 94 (plutonium). The EP-61 primary containment vessel of the 5320 shipping package has been used for storage and transportation of Pu-238 plutonium oxide heat source material.

RTGs are lightweight, compact and extraordinarily reliable spacecraft power systems. They provide electrical power using heat from the natural radioactive decay of plutonium-238 in the form of plutonium dioxide. Pu-238 has been used safely in RPS for space exploration for more than 50 years, and the core General Purpose Heat Source module in a modern RPS has over three decades of design and safety testing behind it. Every RPS launched by NASA has worked precisely as it was designed, with some powering missions for more than 35 years and counting.

Solutions have been analyzed using wet chemical methods and X-ray fluorescence.

Small traces of plutonium-239, a few parts per trillion, and its decay products are naturally found in some concentrated ores of uranium, such as the natural nuclear fission reactor in Oklo, Gabon. In some configurations, the surface temperature of a Pu-238 fuel element can reach 1050 degrees C. These characteristics make Pu-238 the most capable heat generating isotope.

Pu-238 has a half-life of 87.7 years, making it a much longer-lasting source of energy than polonium-210, which was used in the 1959 RTG prototype and has a half-life of 138 days. Pu-238 exhibits high heat density and emits primarily alpha particles, which are easily shielded; this makes it safer to handle than most other radioactive materials.
