Plutonium was first prepared artificially by a team of researchers at the University of California at Berkeley (UCB) in 1941. News of this discovery was not released, however, until 1946. This delay was caused by the need for secrecy about scientific developments during World War II (1939-45).

Neptunium-238 has a half-life of 2.1 days and decays into plutonium-238 through beta decay. Although they conducted their work at the University of California in 1941, their discovery was not revealed to the rest of the scientific community until 1946 because of wartime security concerns.

Recently published work on the chemistry of plutonium (IV) dioxide has shown that PuO2 is not the thermodynamically stable form as was previously thought. ... The implication of this discovery is that a more mobile form of plutonium (i.e. Pu (VI)) than that assumed in the performance assessment (i.e. Pu (IV)) could be...

The discovery of superconductivity in single crystals of PuCoGa5 with transition temperature Tc = 18.5 K is discussed. The existing data lead to the speculation that the superconductivity in PuCoGa5 may be unconventional.

The implication of this discovery is that a more mobile form of plutonium (i.e. Pu (VI)) than that assumed in the performance assessment (i.e. Pu (IV)) could be present in the humid waste disposal environment.
