The isotope Pu-238 is responsible for plutonium with a high heat output. very heat resistant and is stable from room temperature to over 500 degrees stations météo à distance). Dans ces systèmes, différents isotopes comme le plutonium 238 et surtout le strontium 90 ont été utilisés comme sources de chaleur. The process alternatives assume an aqueous feed stream of purified Pu-238 nitrate Effect of sintering temperature on densities of cold-pressed pellets.

The evaluated spontaneous fission half-life of238 Pu has been based on the experimental results given in Table 2. The weighted average of 5 selected values (with reported uncertainties) is 4.74 with an internal uncertainty 0.081 and χ2/ν = 0.72. The adopted value of the 238Pu spontaneous fission is 4.74(12)·1010 years where the uncertainty is 200 gm Pu/batch based on Reactor Grade Pu (very low Pu-238 content); Np anion exchange not used at REDC ~100 gm Effect of temperature on structural changes in Pu 238 dioxide in self-irradiation. I. I. Kapshukov, L. V. Sudakov & G. N. Yakovlev Soviet Atomic Energy volume 31, pages 1420 – 1422 (1972)Cite this article The heat produced by decaying Pu-238 is used as the heat source with a thermocouple. As can be seen in Fig. 2, fins serve as heat sinks to create a voltage across the thermocouple. Thus, the temperature gradient needed for the Seebeck Effect in Curiosity's RTG, results from hot Pu-238 and the cold atmosphere of Mars.

Pu-238 fuels the radioisotope thermoelectric generators (RTGs) that are used in interplanetary research missions. 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.

The power output of Pu-238 is about 0.5 watts/gram, with a half-life of about 87.7 years. At the end of the 87.7 years, the power output is still 0.5 Watts/gram, but there's only half as many grams of Pu-238 left in the original pellet. The rest has changed to U-234 which, with a half-life of 245000 years, doesn't contribute much to the energy
