Explanation

Plutonium-239 (misspelled as 339) is produced artificially in nuclear reactors from Uranium-238. Boron is an effective neutron absorber used in control rods to regulate the fission process. In nature, Uranium-238 is the most abundant isotope, making up about 99.3% of natural uranium compared to only 0.7% for Uranium-235.
