IAEA opens world’s first low Enriched Uranium bank in Kazakhstan

The UN global nuclear watchdog, International Atomic Energy Agency (IAEA) has opened world’s first low Enriched Uranium (LEU) Bank in Oskemen in Kazakhstan.

The bank is owned and managed by IAEA. It will be the first of its kind LEU bank not to be under control of any individual country. The IAEA also manages 123 tons of uranium in Angarsk, Russia but it is under the control of Russian government.

Key Facts

The LEU Bank has reserve capacity to store 90 tons of LEU, the essential ingredient needed to make the fuel for light-water nuclear reactors, which generate electricity. This reserve is enough to fully load a light-water reactor capable of supplying electricity to a large city for three years.

The IAEA has established a series of strict criteria for member state purchasing uranium from the bank. The project was funded by donors, including the United States, European Union, Kuwait, United Arab Emirates, Norway and Nuclear Threat Initiative.

Purpose of Bank

Last resort Supply:  It will serve as last resort source of LEU after IAEA member countries are unable to either produce fuel or if it becomes unavailable on the international market for whatever reason. It will ensure that in the event of an international crisis or similar circumstances, countries dependent on nuclear power would still have access to uranium.

Non-proliferation efforts: It will discourage countries from developing their own uranium enrichment capacities as seen supposedly that peaceful use of enriched uranium can be converted into weapons-grade level.

No disruption to nuclear fuel trade: It will not disrupt usual trade of nuclear fuel purchased in the open market or by bilateral agreement between countries.

Peaceful use of atomic energy: It will ensure peaceful use of atomic energy without the need to develop a costly enrichment program. It will assure that suppliers in the international markets do not manipulate prices or when LEU ceases to be supplied for political reasons.

International Atomic Energy Agency (IAEA)

IAEA is an international 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 as an autonomous organization in 1957 through its own international treaty, the IAEA Statute. It is independent of the United Nations but reports to both the United Nations General Assembly (UNGA) and Security Council (UNSC).The IAEA has its headquarters in Vienna, Austria.

Russian Scientist develop new cheap way to produce nuclear fuel using electricity

Scientists from Russia have developed a new unique, low-cost method for producing high-quality nuclear fuel using electricity.

It is alternative novel method that forms the basis of powder metallurgy and involves electric pulse sintering under pressure.

The main type of fuel for nuclear power reactors is the uranium oxide pellet composition. It is produced from a powder by granulation, pressing, and sintering (coalescing into a solid or porous mass by heating) with the subsequent control of the quality and size of the pellets.

Key Facts
  • In the new method, the mould is heated by passing electric current with the uranium oxide pellet powder placed in.
  • The uranium oxide fuel is simultaneously influenced by the powerful pulse discharge and mechanical pressure
Advantages
  • Products of high quality are obtained in low cost.
  • Reduces number of production stages without increasing the cost.
  • Fuel pellets can be produced even from uranium dioxide powder, which is not suitable for the conventional technology.
