JASON on the Physics of Nuclear Weapons
Despite the extensive data obtained through the conduct of more than 1000 nuclear explosive tests, there is still much that is unknown or imperfectly understood about the science of nuclear weapons.
A newly disclosed report prepared in 2011 by the JASON science advisory panel assessed efforts by the National Nuclear Security Administration (NNSA) to “develop improved understanding of the underlying physics of the materials and components in nuclear weapons.”
The study was released in redacted form last week in response to a Freedom of Information Act request from the Federation of American Scientists. See Hydrodynamic and Nuclear Experiments, JASON report JSR-11-340, November 2011.
More recently, JASON performed “a short study of the science and technology enabling improved measurement, characterization, and understanding of the state of stress in engineered subsurface systems of the Earth’s crust.” See Subsurface Characterization, Jason letter report JSR-14-Task-013, September 2014.
Moreover, the recent decrease in UK government transparency regarding the status of its nuclear arsenal and modernization program reflects a worrisome global trend.
Even without weapons present, the addition of a large nuclear air base in northern Europe is a significant new development that would have been inconceivable just a decade-and-a-half ago.
Empowering U.S. allies to do more so Washington can do and spend less sounds attractive. But enabling, or looking the other way at the spread of nuclear weapons is not in America’s interests anymore today than it was in the 20th century.
As long as nuclear weapons exist, nuclear war remains possible. The Nuclear Information Project provides transparency of global nuclear arsenals through open source analysis. It is through this data that policy makers can call for informed policy change.
