Description
Description: Plutonium is arguably the strangest element in the periodic table and the most difficult to handle in the laboratory. While its nuclear fission properties were correctly predicted well before it was first produced at the Berkeley cyclotron, its chemical and condensed matter properties still defy understanding, largely due to the anomalous behavior of the 5f electrons. Nevertheless, it plays a prominent role in nuclear weapons and nuclear energy production. Former Director Sig Hecker opens the volume with the history of plutonium on planet Earth, its use in nuclear weapons and nuclear energy, the challenge of safeguarding weapons-grade plutonium, and efforts to mitigate health and environmental problems resulting from production during the Cold War. The volume goes on to summarize plutonium's condensed matter properties and evidence for its classification as a correlated-electron material. Other topics cover the role of the 5f electrons in producing plutonium's many phases, plutonium aging, plutonium metallurgy, plutonium chemistry, environmentally-conscious plutonium processing, and long-term deposition of nuclear waste at Yucca Mountain.
