Resende Nuclear Fuel Factory

Last updated

The Nuclear Fuel Factory (FCN) 22°30′14″S44°38′46″W / 22.504°S 44.646°W / -22.504; -44.646 is located near Resende, state of Rio de Janeiro, comprising three units, and has a production capacity of 280 tons of uranium per year. At present, FCN was modernized and produces at the Components and Assembly Unit the fuel rods and fuel elements needed for Brazilian nuclear reactors. The Reconversion and Pellets Production Unit is operating since 1999 with a capacity of 160 tons of UO2 pellets/year. The UO2 reconversion line uses the AUC process. The Nuclear Fuel Factory also produces other fuel element components, such as top and bottom nozzles, spacer grids and end plugs for export demands. Previously, Brazil supplied the uranium, which is transported to Canada where it’s converted into hexafluoride gas (UF6), and then to the United Kingdom for enrichment before it returns to Brazil for fabrication into fuel elements.

The unit has an in-house nuclear safety program and an external one, for environmental monitoring. A nuclear accounting system, internally implemented, required by the Brazilian Nuclear Energy Commission (CNEN) and supervised by the International Atomic Energy Agency (IAEA) continuously performs a balance of the material in processing with a precision reaching tenths of milligrams.

In 2018 a seventh cascade of centrifuges was inaugurated, increasing enrichment capacity by 25%. This gives the plant the capacity to produce about 50% of the annual fuel requirements of Angra Nuclear Power Plant unit 1. The new cascade is the first part of a ten cascade expansion plan. [2]

IAEA Inspections

By late 2003 the International Atomic Energy Agency (IAEA) was negotiating with the Brazilian Government to ensure that the new uranium enrichment facility, due to begin operating in 2005, was properly safeguarded.

In April 2004 the Brazilian Government denied access for the IAEA inspectors to the uranium enrichment facility being built in Resende. [3] The plant, scheduled to begin operation in October 2004, remains subject to IAEA inspections aimed at making sure it is not used for producing weapons-grade material. In February and March 2004 Brazil refused to let IAEA inspectors see equipment in the plant, citing a need to protect proprietary information. The IAEA had dispatched inspectors to Resende who found significant portions of the facility and its contents shielded from view. Walls had been built and coverings are draped over equipment.

By November 2004 the IAEA was able to reach an agreement in principle with the Brazilian government on a safeguards approach to verify the enrichment facilities in Brazil, at the Resende facility. [4] This approach would enable the IAEA to do credible inspections but at the same time take care of Brazil's need to protect certain commercial sensitivity inside the facility.

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 Baghdad Nuclear Research Facility adjacent to the Tuwaitha "Yellow Cake Factory" or Tuwaitha Nuclear Research Center contains the remains of nuclear reactors bombed by Iran in 1980, Israel in 1981, and the United States in 1991. It was used as a storage facility for spent reactor fuel and industrial and medical wastes. The radioactive material would not be useful for a fission bomb, but could be used in a dirty bomb. Following the 2003 invasion of Iraq, the facility was heavily looted by hundreds of Iraqis, though it is unclear what was taken.

In the 1970s and 1980s, during the military regime, Brazil had a secret program intended to develop nuclear weapons. The program was dismantled in 1990, five years after the military regime ended. Brazil is considered to possess no weapons of mass destruction but does have some of the key technologies needed to produce nuclear weapons.

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.

The Chashma Nuclear Power Plant is a large commercial nuclear power plant located at Chashma in Mianwali, Punjab, Pakistan.

In Pakistan, nuclear power is provided by six commercial nuclear power plants with a net capacity of 3,262 megawatts (3.262 GW) from pressurized water reactors. In 2020, Pakistan's nuclear power plants produced a total of 133 terawatt-hours of electricity, which accounted for roughly 10% of the nation's total electric energy generation.

Iran's nuclear program is made up of a number of nuclear facilities, including nuclear reactors and various nuclear fuel cycle facilities.

The Pakistan Nuclear Power Fuel Complex (PNPFC), also known as Chemical Processing Plant (CPP), is a nuclear fuel manufacturing and a fabrication plant located in about 175 km (109 mi) south of Islamabad, possibly in Faisalabad District in Punjab.

The Nuclear Fuel Complex (NFC) was established in 1971 as a major industrial unit of India's Department of Atomic Energy, as a nuclear plant also specializing in supply of nuclear fuel bundles and reactor core components. It is a unique facility where natural and enriched uranium fuel, zirconium alloy cladding and reactor core components are manufactured under one roof.

President Adly Mansour announced on 7 November 2013 that Egypt was restarting its nuclear power program in El Dabaa; a deal was reached with the residents in which it was agreed that a residential area will also be built. The Egyptian minister of electricity, Ahmed Emam, has called the project "necessary" because of a small amount of renewable energy sources and not enough fuel.

Nuclear energy accounts for about 3% of Brazil's electricity. It is produced by two pressurized water reactors at Angra, which is the country's sole nuclear power plant. Construction of a third reactor begun on 1 June 2010, but it is currently stalled. The sole Brazilian company in charge of nuclear energy production is Eletronuclear.

ETRR-2 or ET-RR-2, or is the second nuclear reactor in Egypt supplied by the Argentine company Investigacion Aplicada (INVAP) in 1992. The reactor is owned and operated by Egyptian Atomic Energy Authority (EAEA) at the Nuclear Research Center in Inshas, 60 kilometres (37 mi) northeast of Cairo.

The Fuel Manufacturing Pilot Plant (FMPP), also known as Fuel Element Fabrication Plant, is a nuclear fuel fabrication facility supplied by the Argentine company INVAP in 1998. The FMPP is considered a Material Testing Reactor (MTR)-type fuel element facility, that produces the fuel elements required for the research reactor ETRR-2.

The Hydrometallurgy Pilot Plant (HPP) is a hot cell laboratory complex, dedicated to perform bench-scale radiochemistry experiments including the separation of plutonium and uranium from the spent fuel rods of the ETRR-1 research reactor and was established in 1982. The HPP is owned and operated by the Egyptian Atomic Energy Authority (AEA) at the Nuclear Research Center in Inshas, northeast of Cairo.

Fordow Fuel Enrichment Plant (FFEP) is an Iranian underground uranium enrichment facility located 20 miles (32 km) northeast of the Iranian city of Qom, near Fordow village, at a former Islamic Revolutionary Guard Corps base. The site is under the control of the Atomic Energy Organization of Iran (AEOI). It is the second Iranian uranium enrichment facility, the other one being that of Natanz. According to the Institute for Science and International Security, possible coordinates of the facility's location are: 34.88459°N 50.99596°E.

2021 Natanz incident refers to a suspected attack on the Natanz nuclear site in Iran. The Natanz nuclear facility is placed in the wilderness in the central province of Isfahan, Iran. This site is scouted by the International Atomic Energy Agency (IAEA), the U.N. nuclear watchdog.
