Technicians at the Nevada National Security Site make final adjustments to the "Leda" experimental vessel in the "Zero Room" at the underground U1a facility.
Hydrodynamic experiments such as Leda involve non-nuclear surrogate materials that mimic many of the properties of nuclear materials. "This experiment ultimately enhances confidence in our ability to predictively model and assess weapon performance in the absence of full-scale underground nuclear testing," said Webster. Nicknamed "Leda," it provides key data for Stockpile Stewardship. LOS ALAMOS, N.M. Sept. 8, 2014—Los Alamos National Laboratory has successfully fired the latest in a series of experiments at the Nevada National Security Site (NNSS). "Leda is an integrated experiment that provides important surrogate hydrodynamic materials data in support of the Laboratory's stewardship of the U. S. nuclear deterrent," said Bob Webster, Associate Director for Weapons Physics.
