Nuclear Non-proliferation
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "List of states with nuclear weapons, Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the ''Non-Proliferation Treaty'' or ''NPT''. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (up to and including the so-called countervalue targeting of civilians with nuclear weapons), de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states. Four countries besides the five recognized Nuclear Weapons States have acquired, or are presumed to have acquired, nuclear weapons: India, Pakistan, North Korea, and Israel. None of these four is a party to the NPT, although North Korea acceded to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Weapons
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

Combined Development Trust
The Combined Development Agency (CDA), originally the Combined Development Trust (CDT), was a defense purchasing authority established in 1944 by the governments of the United States and the United Kingdom. Its role was to ensure adequate supplies of uranium for the respective countries weapons development programs. The agency initiated a range of incentives to several countries to encourage exploration and a fast buildup of mineral reserves. The main countries targeted for the programs were the US, Canada, South Africa, and to a limited extent Australia. The countries tried to monopolize on the resources of the territories they owned or that had hardly any claim. The Belgian Congo was an example of the third world place that was used for its resources. In Australia, uranium ore from a number of mines was processed at the purpose built Port Pirie Uranium Treatment Complex which operated under contract to the CDA by the Government of South Australia between 1955 and 1962.

Nuclear Ethics
Nuclear ethics is a cross-disciplinary field of academic and policy-relevant study in which the problems associated with nuclear warfare, nuclear deterrence, nuclear arms control, nuclear disarmament, or nuclear technology, nuclear energy are examined through one or more Ethics, ethical or Morality, moral theories or frameworks. In contemporary security studies, the problems of nuclear warfare, deterrence, Nuclear proliferation, proliferation, and so forth are often understood strictly in political, strategic, or military terms. In the study of international organizations and law, however, these problems are also understood in legal terms. Nuclear ethics assumes that the very real possibilities of human extinction, mass human destruction, or mass environmental damage which could result from nuclear warfare are deep ethical or moral problems. Specifically, it assumes that the outcomes of human extinction, mass human destruction, or environmental damage count as moral evils. Another ...

Fissile Material
In nuclear engineering, fissile material is material capable of sustaining a nuclear fission chain reaction. By definition, fissile material can sustain a chain reaction with neutrons of thermal energy. The predominant neutron energy may be typified by either slow neutrons (i.e., a thermal system) or fast neutrons. Fissile material can be used to fuel thermal-neutron reactors, fast-neutron reactors and nuclear explosives. Fissile vs fissionable According to the Ronen fissile rule, for a heavy element with 90 ≤ ''Z'' ≤ 100, its isotopes with , with few exceptions, are fissile (where ''N'' = number of neutrons and ''Z'' = number of protons).The fissile rule thus formulated indicates 33 isotopes as likely fissile: Th-225, 227, 229; Pa-228, 230, 232; U-231, 233, 235; Np-234, 236, 238; Pu-237, 239, 241; Am-240, 242, 244; Cm-243, 245, 247; Bk-246, 248, 250; Cf-249, 251, 253; Es-252, 254, 256; Fm-255, 257, 259.

United Nations Security Council
The United Nations Security Council (UNSC) is one of the Organs of the United Nations, six principal organs of the United Nations (UN) and is charged with ensuring international security, international peace and security, recommending the admission of new UN members to the United Nations General Assembly, General Assembly, and approving any changes to the UN Charter. Its powers include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with the authority to issue binding United Nations Security Council resolution, resolutions on member states. Like the UN as a whole, the Security Council was created after World War II to address the failings of the League of Nations in maintaining world peace. It held its first session on 17 January 1946 but was largely paralyzed in the following decades by the Cold War between the United States and the Soviet Union (and their allies). Nevertheless, it authorized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acheson–Lilienthal Report
The ''Report on the International Control of Atomic Energy'' was written by a committee chaired by Dean Acheson and David Lilienthal in 1946 and is generally known as the Acheson–Lilienthal Report or Plan. The report was an important American document that appeared just before the start of the early Cold War. It proposed the international control of nuclear weapons and the avoidance of future nuclear warfare. A version, the Baruch Plan, was vetoed by the USSR at the UN. Historical context Two schools of thought concerning nuclear weapons emerged in the United States immediately after the end of World War II. One school, which had Secretary of War Henry Stimson as its chief proponent, believed that the apparent secrets of the atomic bomb were scientific in nature, and could not be monopolised forever. They further felt that to hold the bomb ostentatiously in reserve, whilst negotiating with the Soviet Union not to develop one, would simply drive Russia into developing their own ...

United Nations Atomic Energy Commission
The United Nations Atomic Energy Commission (UNAEC) was founded on 24 January 1946 by the very first resolution of the United Nations General Assembly "to deal with the problems raised by the discovery of atomic energy." The General Assembly asked the Commission to "make specific proposals: (a) for extending between all nations the exchange of basic scientific information for peaceful ends; (b) for control of atomic energy to the extent necessary to ensure its use only for peaceful purposes; (c) for the elimination from national armaments of atomic weapons and of all other major weapons adaptable to mass destruction; (d) for effective safeguards by way of inspection and other means to protect complying States against the hazards of violations and evasions." On 14 December 1946, the General Assembly passed a follow-up resolution urging an expeditious completion of the report by the Commission as well as its consideration by the United Nations Security Council.

Bernard Baruch
Bernard Mannes Baruch (August 19, 1870 – June 20, 1965) was an American financier and statesman. After amassing a fortune on the New York Stock Exchange, he impressed President Woodrow Wilson by managing the nation's economic mobilization in World War I as chairman of the War Industries Board. He advised Wilson during the Paris Peace Conference. He made another fortune in the postwar bull market, but foresaw the Wall Street crash and sold out well in advance. In World War II, he became a close advisor to President Roosevelt on the role of industry in war supply, and he was credited with greatly shortening the production time for tanks and aircraft. Later he helped to develop rehabilitation programs for injured servicemen. In 1946, he was the United States representative to the United Nations Atomic Energy Commission (UNAEC), though his Baruch Plan for international control of atomic energy was rejected by the Soviet Union.

Baruch Plan
The Baruch Plan was a proposal by the United States government, written largely by Bernard Baruch but based on the Acheson–Lilienthal Report, to the United Nations Atomic Energy Commission (UNAEC) during its first meeting in June 1946. The United States, Great Britain and Canada had called for an international organization to regulate atomic energy, and President Truman responded by asking Undersecretary of State Dean Acheson and David E. Lilienthal to draw up a plan. Baruch's version of the proposal was rejected by the Soviet Union, who feared the plan would preserve the American nuclear monopoly. Its collapse led to the beginning of the Cold War arms race. Description In the Plan, the US agreed to decommission all of its atomic weapons and transfer nuclear technology on the condition that all other countries pledged not to produce atomic weapons and agreed to an adequate system of inspection, including monitoring, policing, and sanctions. The Plan also proposed to internation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
