(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.

To perform an analysis of a target nitrate/nitrite system related to the separation of Np and Pu for Pu-238 production, a flow cell was used for continuous sampling of a liquid slipstream.

RTGs convert heat generated by decaying plutonium-238 (Pu-238) fuel into electricity.
The remainder, due to its age, does not meet specifications, but can be blended with newly produced Pu-238 to extend the usable inventory.
Releasing Space in PF-4 by Moving Pu-238 Work Offsite

Another option (not shown) would be to build one module for Pu-238
Technologies and developments that utilize these tools inclu de: continuous dissolution of naval fuels with on-line monitoring and control of fluoride complexation; dissolution chemistry for sand-slag-crucible plutonium residues, for Russian Sapphire U-Be fuel, and for irradiated neptunium oxide in aluminum targets for Pu-238 production; extraction of actinides in the presence of zirconium in acidic solutions; and development of a non-mercury catalyst, fluoboric acid, for dissolving aluminum nuclear fuels in nitric acid.
One isotope, Pu-238, is released upriver in minuscule amounts by the Department of Energy's Savannah River Plant, a nuclear facility.
Both could be done, for example, by moving pit casting or work on plutonium-238 (Pu-238), which is much more radioactive than the plutonium used in weapons, out of PF-4.
Another option is to use buildings at Idaho National Laboratory or Savannah River Site (SRS) (SC); both sites have done work with Pu-238.
