DOE marks 75th anniversary of Trinity Test by highlighting cleanup progress

On July 16, 1945, the research and development efforts of the nation’s once-secret Manhattan Project were realized when the detonation of the world’s first atomic device occurred in Alamogordo, N.M., more than 200 miles south of Los Alamos, in what was code-named the Trinity Test—a name inspired by the poems of John Donne.

On the 75th anniversary of this landmark event, the Department of Energy’s Office of Environmental Management (EM) is highlighting the cleanup, long-term management, and historical significance of the Manhattan Project sites—Los Alamos, Oak Ridge, Tenn., and Hanford, Wash.—that were conceived, built, and operated in secrecy as they supported weapons development during World War II.

ANS Nuclear Cafe Matinee: DUFF Space Nuclear Reactor Prototype

A joint Department of Energy and NASA team has demonstrated a simple, robust fission reactor prototype [note: see Comments for more accurate and complete description] intended for development for future space exploration missions. The DUFF (Demonstration Using Flattop Fissions) experiment represents the first demonstration in the United State-since 1965-of a space nuclear reactor system to produce electricity.
