On September 24, 1996, President Clinton signed the Comprehensive Nuclear Test Ban Treaty at the United Nations Headquarters. Over the next five months, 141 nations, including the four other nuclear weapon statesâ€"Russia, China, France, and the United Kingdomâ€"added their signatures to this total ban on nuclear explosions. To help achieve verification of compliance with its provisions, the treaty specifies an extensive International Monitoring System of seismic, hydroacoustic, infrasonic, and radionuclide sensors. This volume identifies specific research activities that will be needed if the United States is to effectively monitor compliance with the treaty provisions.

The contributors to this book describe, discuss, and evaluate the normative reframing brought about by the Treaty on the Prohibition of Nuclear Weapons (the Ban Treaty), taking you on a journey through its genesis and negotiation history to the shape of the emerging global nuclear order. Adopted by the United Nations on 7 July 2017, the Ban Treaty came into effect on 22 January 2021. For advocates and supporters, weapons that were always immoral are now also illegal. To critics, it represents a profound threat to the stability of the existing global nuclear order with the Nuclear Non-proliferation Treaty as the normative anchor. As the most significant leap in nuclear disarmament in fifty years and a rare case study of successful state-civil society partnership in multilateral diplomacy, the Ban Treaty challenges the established order. The book’s contributors are leading experts on the Ban Treaty, including senior scholars, policymakers and civil society activists. A vital guide to the Ban Treaty for students of nuclear disarmament, arms control and diplomacy as well as for policymakers in those fields.

Nuclear Weapons under International Law is a comprehensive treatment of nuclear weapons under key international law regimes. It critically reviews international law governing nuclear weapons with regard to the inter-state use of force, international humanitarian law, human rights law, disarmament law, and environmental law, and discusses where relevant the International Court of Justice's 1996 Advisory Opinion. Unique in its approach, it draws upon contributions from expert legal scholars and international law practitioners who have worked with conventional and non-conventional arms control and disarmament issues. As a result, this book embraces academic consideration of legal questions within the context of broader political debates about the status of nuclear weapons under international law.

Despite their Cold War rivalry, the United States and the Soviet Union frequently engaged in joint efforts to prevent the spread of nuclear weapons. Leaders in Washington and Moscow recognized that nuclear proliferation would serve neither country’s interests even when they did not see eye-to-eye in many other areas. They likewise understood why collaboration in mitigating this nuclear danger would serve both their own interests and those of the international community. This volume examines seven little known examples of US-Soviet cooperation for non-proliferation, including preventing South Africa from conducting a nuclear test, developing international safeguards and export control guidelines, and negotiating a draft convention banning radiological weapons. It uses declassified and recently-digitized archival material to explore in-depth the motivations for and modalities for cooperation under often adverse political circumstances. Given the current disintegration of Russian and US relations, including in the nuclear sphere, this history is especially worthy of review. Accordingly, the volume’s final chapter is devoted to discussing how non-proliferation lessons from the past can be applied today in areas most in need of US-Russian cooperation.

This document lists chronologically and alphabetically by name all nuclear tests and simultaneous detonations conducted by the United States from July 1945 through September 1992. Two nuclear weapons that the United States exploded over Japan ending World War II are not listed. These detonations were not "tests" in the sense that they were conducted to prove that the weapon would work as designed (as was the first test near Alamogordo, New Mexico on July 16, 1945), or to advance nuclear weapon design, or to determine weapons effects, or to verify weapon safety as were the more than one thousand tests that have taken place since June 30,1946. The nuclear weapon (nicknamed "Little Boy") dropped August 6,1945 from a United States Army Air Force B-29 bomber (the Enola Gay) and detonated over Hiroshima, Japan had an energy yield equivalent to that of 15,000 tons of TNT. The nuclear weapon (virtually identical to "Fat Man") exploded in a similar fashion August 9, 1945 over Nagaski, Japan had a yield of 21,000 tons of TNT. Both detonations were intended to end World War II as quickly as possible. Data on United States tests were obtained from, and verified by, the U.S. Department of Energy's three weapons laboratories -- Los Alamos National Laboratory, Los Alamos, New Mexico; Lawrence Livermore National Laboratory, Livermore, California; and Sandia National Laboratories, Albuquerque, New Mexico; and the Defense Threat Reduction Agency. Additionally, data were obtained from public announcements issued by the U.S. Atomic Energy Commission and its successors, the U.S. Energy Research and Development Administration, and the U.S. Department of Energy, respectively.
