(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.

The Power Supply Live Unit Manufacture to Support Baseline Review Team was honored for re-establishing a defense-related pu-238 power supply manufacturing capability.
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
worked with Pu-238 and have stated that they have, or could modify,
full amount of space used for Pu-238 in PF-4, 9,600 sf, to be made
Option 2 would move the Pu-238 MAR contained in 5,000 sf of PF-4 to
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.
Another option is to use buildings at Idaho National Laboratory or Savannah River Site (SRS) (SC); both sites have done work with Pu-238.
What are the pros, cons, and costs of Pu-238 options?
Plutonium-238 (Pu-238): Pu-238 is highly radioactive.
Three main tasks contribute to MAR in PF-4: Pu-238 work, pit fabrication, and recovery of plutonium from acid solution.
