Isolation of 239Pu from Uranium Oxide Irradiated JRR-1

Isolation of 239Pu from Uranium Oxide Irradiated JRR-1

Natural or depleted uranium targets were irradiated in JRR-1 with 1011n/sec⋅cm2 flux for 3060hr. After setting the irradiated target aside for a few months in a hot-cave, 239Pu was isolated by TBP solvent extraction method from bulk of uranium and the fission products and then purified by an anion-e...

Zusammenfassung:Natural or depleted uranium targets were irradiated in JRR-1 with 1011n/sec⋅cm2 flux for 3060hr. After setting the irradiated target aside for a few months in a hot-cave, 239Pu was isolated by TBP solvent extraction method from bulk of uranium and the fission products and then purified by an anion-exchange method. It was found that 239Pu thus obtained was not contaminated with uranium and 210Po. However, it contained β, γ-activity of about 30 days half-life slightly.
