Fifty years after publication of the original Plutonium Handbook, this timely and authoritative 2nd edition provides unparalleled coverage of plutonium research. The greatly expanded 2nd edition contains six volumes of research content and a seventh volume as a complete index. (Each individual volume also has its own index). Topics span the history of the discovery of plutonium, properties of plutonium isotopes, chemistry and properties of plutonium metal and alloys, plutonium aging, thermodynamic trends of plutonium, plutonium in nuclear fuels, waste forms, and heat sources, packaging, storing, and transportation of plutonium, nuclear security and safeguards, and techniques for working with plutonium. With authorship from 13 countries, this truly international collaboration brings together an entire community of researchers from academia, national laboratories, and research institutions. The Plutonium Handbook (2nd edition) is expertly produced and will be a mainstay for generations.
