NNSA’s current quarterly summary of experiments conducted as part of its Science-Based Stockpile Stewardship Program is now available here.
The quarterly summary prepared by NNSA’s Office of Defense Programs provides descriptions of key NNSA facilities that conduct stockpile stewardship experiments. These include some of the most sophisticated scientific research facilities in the world, including the Dual Axis Radiographic Hydrodynamic Test facility at Los Alamos National Laboratory, National Ignition Facility at Lawrence Livermore National Laboratory, and the Z machine at Sandia National Laboratories. The summary also provides the number of experiments performed at each facility during each quarter of the fiscal year.
The U.S. Stockpile Stewardship Program sustains and assesses the nuclear weapons stockpile without the use of underground nuclear tests. The experiments carried out within the program are used in combination with complex computational models and NNSA’s Advanced Simulation and Computing (ASC) Program to assess the safety, security and effectiveness of the stockpile.

Sandia’s Z machine is the world's most powerful and efficient laboratory radiation source. It uses high magnetic fields associated with high electrical currents to produce high temperatures, high pressures, and powerful X-rays for research in high energy density science. Photo by Randy Montoya.
