Detection of Nuclear Weapons and Materials: Science, Technologies, Observations

Description: The United States currently uses several types of nuclear detection equipment. All have significant shortcomings. Some work only at very short range; some cannot identify the material emitting radiation, which can lead to false alarms and interrupt commerce; some depend on operator skill, and may be defeated by a clever smuggler or a sleepy operator; and some are easily defeated by shielding. In an effort to overcome such problems, Congress has funded a pipeline of advanced-technology research, development, and acquisition. This report seeks to help Congress understand this technology. It discusses the science of detecting nuclear weapons and materials, describes nine advanced U.S. technologies selected to illustrate the range of projects in the pipeline, and offers observations for Congress.

Detection of Nuclear Weapons and Materials: Science, Technologies, Observations

Description: Nuclear weapons contain special nuclear material (SNM), which produces unique or suspect signatures that can be detected. This report seeks to help Congress understand this technology. It discusses the science of detecting nuclear weapons and materials, describes nine advanced U.S. technologies selected to illustrate the range of projects in the pipeline, and offers observations for Congress. The report does not compare technologies.

U.S. Nuclear Weapons Policy: Considering "No First Use"

Description: This report have discusses the benefits and risks of the U.S. nuclear weapons policy, known as a "no first use" pledge. U.S. officials have repeatedly stated that the United States could, under certain circumstances, use nuclear weapons against a state, even if the latter has not already done so.

Nuclear Weapons R&D Organizations in Nine Nations

Description: This report describes the organizations controlling research and development (R&D) on nuclear weapons in several nations, and presents a brief history of the organizations controlling nuclear weapons R&D in the United States. It discusses whether these organizations are civilian or military, though in many nations the lines between civilian and military are blurred.

Brazilian Trade Policy and the United States

Description: As the largest and one of the most influential countries in Latin America, Brazil has emerged as a leading voice for developing countries in setting regional and multilateral trade agendas. Brazil is critical of U.S. trade policies such as the Byrd Amendment (repealed, but program in effect until October 1, 2007), which directs duties from trade remedy cases to affected industries, the administration of trade remedy rules, and what it considers to be discriminatory treatment in the U.S. expansion of free trade agreements in Latin America. Despite the differences, both countries recognize the potential for important gains to be had from mutually acceptable trade liberalization at all levels.

Nuclear Weapons R&D Organizations in Nine Nations

Description: As an aid to Congress in understanding nuclear weapons, nuclear proliferation, and arms control matters, this report describes which agency is responsible for research and development (R&D) of nuclear weapons (i.e., nuclear explosive devices, as distinct from the bombers and missiles that deliver them) in the nine nations with nuclear weapons and whether these agencies are civilian or military. It also traces the history of such agencies in the United States from 1942 to the present.

Comprehensive Nuclear-Test-Ban Treaty: Background and Current Developments

Description: This report discusses the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which bans all nuclear explosion and was in 1996 adopted by the U.N. General Assembly but rejected by the U.S. Senate in 1997. This report discusses the Obama Administration's stated goal of pursuing U.S. ratification of the CTBT, although the Administration has mainly focused on securing Senate consent to ratification of the New Strategic Arms Reduction Treaty (New START). This report also discusses other nuclear weapons-related issues as well as the long history of nuclear testing.

Technical Concept-Operation Bren

Description: From Abstract: "The Oak Ridge National Laboratory (ORNL) Health Physics Research Reactor is to be attached to a hoist platform on a 1500-ft tower at the Nevada Test Site (NTS). The project is a continuation of the studies commenced in 1956 for evaluating the radiation doses of persons exposed to nuclear weapons, especially the residents of Hiroshima and Nagaski, Japan. Measurements will be made of the energy, angular, and spatial distributions of the radiation from the reactor."
