Effects Of Nuclear Earth Penetrator And Other Weapons

Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.

In this study, CISAC tackles the technical dimensions of a longstanding controversy: To what extent could existing and plausibly attainable measures for transparency and monitoring make possible the verification of all nuclear weaponsâ€"strategic and nonstrategic, deployed and nondeployedâ€"plus the nuclear-explosive components and materials that are their essential ingredients? The committee's assessment of the technical and organizational possibilities suggests a more optimistic conclusion than most of those concerned with these issues might have expected.

The Bush Admin. completed its congressionally-mandated Nuclear Posture Review in Dec. 2001. The review led to major changes in U.S. nuclear policy. It found that the Cold War relationship with Russia was "very inappropriate" and that the U.S. must be able to deal with new threats. It planned to retain Cold War-era nuclear weapons, which would suffice for many contingencies, though at reduced numbers. To complement these weapons so as to improve U.S. ability to deal with new, more dispersed threats in various countries, the Admin. sought to explore additional nuclear capabilities. Accordingly, the FY2004 request included four nuclear weapon initiatives.

This overview aims to inform the public discussion of space-based weapons by examining their characteristics, potential attributes, limitations, legality, and utility. The authors do not argue for or against space weapons, nor do they estimate the potential costs and performance of specific programs, but instead sort through the realities and myths surrounding space weapons in order to ensure that debates and discussions are based on fact.

Nuclear, biological and chemical weapons are designed to cause destruction on a vastly greater scale than any conventional weapons, with the potential to kill thousands in a single attack and with effects that may persist in the environment and in our bodies indefinitely. This report by the independent Weapons of Mass Destruction Commission, chaired by Dr Hans Blix, sets out 60 recommendations on how the world community, national governments and civil society should address this global challenge under the following headings: preventing the proliferation of nuclear weapons; preventing nuclear terrorism; reducing the threat and numbers of existing nuclear weapons; moving from regulating nuclear weapons to outlawing them; biological and toxin weapons; chemical weapons; weapons of mass destruction (WMD) delivery means, missile defences and weapons in space; export controls, international assistance and non-governmental actors; compliance, verification, enforcement and the role of the United Nations.
