LANL News:

Los Alamos National Laboratory’s role in the development of nuclear weapons during the Cold War period of 1947 to 1991 will be discussed by Byron Ristvet of the Defense Threat Reduction Agency at 5:30 p.m., Sept. 11 at the Laboratory’s Bradbury Science Museum. The talk is part of the Laboratory’s 70th anniversary lecture series.

“Los Alamos National Laboratory’s role in conjunction with the Department of Defense in meeting this challenge with new nuclear weapon designs was an amazingly complex and intellectual endeavor,” Ristvet said.

Ristvet also will talk about the need for development of nuclear weapons from the target design-testing-stockpile sequence, and emphasize the importance of nuclear weapons testing toward ensuring that U.S. nuclear weapons systems will be reliable and provide for the defense of the nation.

Ristvet is a senior subject matter expert to the Defense Threat Reduction Agency’s Research and Development Directorate in the areas of nuclear and conventional weapons effect and testing, hard and deeply-buried target characterization and defeat, counterterrorism, cooperative threat reduction, knowledge preservation and nuclear test readiness. He has served in a number of nuclear weapons related positions, including the Defense Nuclear Weapons School, as an International Atomic Energy Agency technical advisor, and as an instructor/mentor in several nuclear weapons training programs, including at Sandia National Laboratories.
