Joint Comprehensive Plan Of Action
The Joint Comprehensive Plan of Action (JCPOA; (, BARJAM)), also known as the Iran nuclear deal or Iran deal, is an agreement to limit the Iranian nuclear program in return for sanctions relief and other provisions. The agreement was finalized in Vienna on 14 July 2015, between Iran and the P5+1 (the five permanent members of the United Nations S.C.—China, France, Russia, the U.K., U.S.—plus Germany) together with the European Union. Formal negotiations began with the adoption of the Joint Plan of Action, an interim agreement signed between Iran and the P5+1 countries in November 2013. Iran and the P5+1 countries engaged in negotiations for the following 20 months and, in April 2015, agreed on an Iran nuclear deal framework, which later led to JCPOA, along with a Roadmap Agreement between Iran and the International Atomic Energy Agency (IAEA). Negotiations centered around sanctions relief and restrictions on Iran's nuclear facilities, including the Arak IR-40 reactor ...

Sanctions Against Iran
There have been a number of international sanctions against Iran imposed by a number of countries, especially the United States, and international entities. Iran was the most sanctioned country in the world until it was surpassed by Russia, following Russia's invasion of neighboring Ukraine in February 2022. The first sanctions were imposed by the United States in November 1979,Haidar, J.I., 2017Sanctions and Exports Deflection: Evidence from Iran," Economic Policy (Oxford University Press), April 2017, Vol. 32(90), pp. 319-355. after a group of radical students seized the American Embassy in Tehran and took hostages. These sanctions were lifted in January 1981 after the hostages were released, but they were reimposed by the United States in 1987 in response to Iran's actions from 1981 to 1987 against the U.S. and vessels of other countries in the Persian Gulf and US claims of Iranian support for terrorism. The sanctions were expanded in 1995 to include firms dealing with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Nations Security Council
The United Nations Security Council (UNSC) is one of the six principal organs of the United Nations (UN) and is charged with ensuring international peace and security, recommending the admission of new UN members to the General Assembly, and approving any changes to the UN Charter. Its powers as outlined in the United Nations Charter include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with authority to issue resolutions that are binding 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 paralysed in the following decades by the Cold War between the United States and the Soviet Union (and their allies). Nevertheless, it authorized military interventions in the Korean War and the Congo Crisis and peaceke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Proliferation
Nuclear proliferation is the spread of nuclear weapons to additional countries, particularly those 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''. Nuclear proliferation occurs through the spread of fissile material, and the technology and capabilities needed to produce it and to Nuclear weapon design, design and manufacture nuclear weapons. In a modern context, it also includes the spread of nuclear weapons to non-state actors. 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 (including the so-called countervalue targeting of civilians), de-stabilize international relations, or infringe upon the principle of Sovereign state, state sovereignty. Conversely, supporters of deterrence theory arg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressurized Heavy-water Reactor
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure to avoid boiling, allowing it to reach higher temperature (mostly) without forming steam bubbles, exactly as for a pressurized water reactor (PWR). While heavy water is very expensive to isolate from ordinary water (often referred to as ''light water'' in contrast to ''heavy water''), its low absorption of neutrons greatly increases the neutron economy of the reactor, avoiding the need for enriched fuel. The high cost of the heavy water is offset by the lowered cost of using natural uranium and/or alternative fuel cycles. As of the beginning of 2001, 31 PHWRs were in operation, having a total capacity of 16.5 GW(e), representing roughly 7.76% by number and 4.7% by generating capacity of all curre ...

Gas Centrifuge
A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container. A prominent use of gas centrifuges is for the separation of uranium-235 (235U) from uranium-238 (238U). The gas centrifuge was developed to replace the gaseous diffusion method of 235U extraction. High degrees of separation of these isotopes relies on using many individual centrifuges arranged in series that achieve successively higher concentrations. This process yields higher concentrations of 235U while using significantly less energy compared to the gaseous diffusion process. History Suggested in 1919, the centrifugal process was first successfully performed in 1934. American scientist Jesse Beams and his team at the University of Virginia developed the process by separating two isotopes of chlorine, chlori ...

Enriched Uranium
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2732–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7210%), and uranium-234 (234U, 0.0049–0.0059%). 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. Low-enriched uranium (20% 235U, typically >85%) is used for the cores of many nuclear weapons, as well as compact reactors for naval propulsion and research, as well as breeder reactors. There are about 2,000 tonnes of highly enriched uranium in the world. Enrichment methods were first developed on a large scale by the Manhattan Project. Its gaseous diffusion method was used in the 194 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximum Pressure Campaign
Maximum pressure campaign refers to the intensified sanctions against Iran by the Trump administration after the United States exited the Joint Comprehensive Plan of Action (JCPOA) in 2018. The campaign was aimed at pressuring Iran to renegotiate the JCPOA, adding more restrictions on Iran's nuclear program and expanding the scope of the agreement to cover Iran's ballistic missiles as well as other regional activities. This strategy was faced by Iran's counter pressure policy to thwart the U.S. maximum pressure campaign. According to Human Rights Watch, the current economic sanctions are causing “unnecessary suffering to Iranian citizens afflicted with a range of diseases and medical conditions," despite exemptions for the humanitarian goods. In February 2025, amidst the Iranian energy and economic crises, Trump signed an executive order to restore the maximum pressure policy against the Iranian regime. Sanctions In May 2018, then U.S. president Donald Trump withdrew from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Principlists
The Principlists (, ), also interchangeably known as the Iranian Conservatives Open access material licensed under the Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported License. and formerly referred to as the Right or Right-wing, are one of two main political camps in post-revolutionary Iran; the Reformists are the other camp. The term '' hardliners'' that some western sources use in the Iranian political context usually refers to the faction, although the principlist camp also includes more centrist tendencies. The faction rejects the status quo internationally, but favors domestic preservation. Within Iranian politics, "principlist" refers to the conservative supporters of the Supreme Leader of Iran and advocates for protecting the ideological "principles" of the Islamic Revolution's early days. According to Hossein Mousavian, "The Principlists constitute the main right-wing/conservative political movement in Iran. They are more religiously oriented and more ...
