The member states of the International Atomic Energy Agency (IAEA) are those states which have joined the international organization that seeks to promote the peaceful use of nuclear energy, and to inhibit its use for any military purpose, including nuclear weapons. The IAEA was established as an autonomous organization on 29 July 1957. Though established independently of the United Nations through its own international treaty, the IAEA Statute, [1] the IAEA reports to both the UN General Assembly and Security Council. During 1956, an IAEA Statute Conference was held to draft the founding documents for the IAEA, and the IAEA Statute was completed at a conference in 1957.

    The International Atomic Energy Agency (IAEA) is an intergovernmental organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for any military purpose, including nuclear weapons. It was established in 1957 as an autonomous organization within the United Nations system; though governed by its own founding treaty, the organization reports to both the General Assembly and the Security Council of the United Nations, and is headquartered at the UN Office at Vienna, Austria.

    <span class="mw-page-title-main">Treaty on the Non-Proliferation of Nuclear Weapons</span> International treaty

    The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.

    <span class="mw-page-title-main">Nuclear proliferation</span> Spread of nuclear weapons

    Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "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, de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.

    The International Nuclear Information System (INIS) hosts one of the world's largest collections of published information on the peaceful uses of nuclear science and technology.

    Iran has research sites, two uranium mines, a research reactor, and uranium processing facilities that include three known uranium enrichment plants.

    The United Nations General Assembly has granted observer status to international organizations, entities, and non-member states, to enable them to participate in the work of the United Nations General Assembly, though with limitations. The General Assembly determines the privileges it will grant to each observer, beyond those laid down in a 1986 Conference on treaties between states and international organizations. Exceptionally, the European Union (EU) was in 2011 granted the right to speak in debates, to submit proposals and amendments, the right of reply, to raise points of order and to circulate documents, etc. As of May 2011, the EU is the only international organization to hold these enhanced rights, which has been likened to the rights of full membership, short of the right to vote.

    A nuclear fuel bank is reserve of low enriched uranium (LEU) for countries that need a backup source of LEU to fuel their nuclear reactors. Countries that do have enrichment technology would donate enriched fuel to a "bank", from which countries not possessing enrichment technology would obtain fuel for their power reactors.

States parties are legally obligated to co-operate with the Court when it requires, such as in arresting and transferring indicted persons or providing access to evidence and witnesses. States parties are entitled to participate and vote in proceedings of the Assembly of States Parties, which is the Court's governing body. Such proceedings include the election of such officials as judges and the Prosecutor, the approval of the Court's budget, and the adoption of amendments to the Rome Statute.
