The safety criteria that have been specified for modern nuclear weapons are very demanding. The majority of the weapons in the current stockpile will have to be modified to meet them, unless they are retired. Moreover, for some weapons we still lack necessary data to perform credible safety analyses. Although plutonium dispersal is a much less threatening danger than a sizable nuclear yield, it is nevertheless a potentially serious hazard, particularly if the plutonium is aerosolized in a chemical detonation. The panel recommended the following actions: (1) equip all stockpiled weapons with Enhanced Nuclear Detonation Safety, and build all aircraft-launched bombs and cruise missiles with insensitive high explosive and fire-resistant cores; (2) began an immediate review of the acceptability of retaining missile systems without IHE, fire-resistant cores, or 1.3 class propellant in close proximity to the warheads; (3) continue safety studies and allocate necessary resources to weapons and military laboratories; (4) affirm enhanced safety as the top priority goal of the US nuclear weapons program, and design all future weapons to be as safe as practically achievable, consistent with reasonable military requirements.
