Russia 1st to test 10Gen uranium enrichment centrifuges



RIA Novosti / A. Solomonov





Rosatom, Russia’s nuclear agency, confirms scientists are testing 10th generation centrifuges. No other country even possesses 9th gen tech, putting Rosatom years ahead of the competition.

“We’re on to 10 Gen,” announced Aleksandr Belousov, general director of Urals Integrated Electrochemical Plant (UIEP), a Rosatom subsidiary in Novouralsk, Sverdlovsk Region, in the Urals.

“Scientists and engineers are solving technical issues, which is quite difficult. Any kind of new research and technological development is a venture undertaking, you can either succeed or fail... Any new machinery must be economically efficient. [10Gen] is being developed out of economic expediency, not for mere modernization. The more energy-intensive the machinery is, the more technical problems emerge,” Belousov said.

A gas centrifuge uses principles of centrifugal force to perform radioisotope separation of gases, by accelerating molecules to such an extent that particles of different masses are physically separated within a rotating container.

The centrifugal separation of isotopes is used for various purposes. First of all for production of low-enriched (up to 3-4 percent) uranium to be used as fuel at nuclear power plants. It also is used to produce weapons-grade, highly-enriched uranium (90 percent of U-235). Centrifuges are also needed to produce radioisotopes for medicine and various technical issues.



Centrifuges are operated in cascades of hundreds and thousands units. Manufacturer supplies centrifuges in assemblies of 20 units in two rows, and at the factory they are placed on the columns in tiers, one above the other.

Last week the second cascade unit of 9 Gen gas centrifuges has become operable at the UIEP, with the first 9 Gen unit introduced in late December 2013. Having two 9 Gen centrifuge cascades means that UIEP is the leader in the industry, making up to 48 percent of Russian radioisotope market and 20 percent of the global market, RIA Novosti reports.

The 9 Gen centrifuges are four times more productive than 8 Gen centrifuges, which means a similar productivity pace should be applied to 10 Gen units, Belousov said.

Development of nuclear enrichment centrifuges in the Soviet Union began in 1952. Over the time general dimensions of the machinery changed a little yet the productivity has augmented by 14 times, whereas operating costs have diminished by at least 10 times, aide to the UIEP head, Gennady Solovyov, said.

The modern Russian centrifuge is a state-of-the-art component made of composite materials and special aluminum alloy. Its rotor spins with unbelievable speed of 1,000 rotations per second and can do it without a single stop for 30 years. Mechanical malfunctions are extremely rare, no more than 0.1 percent (one failure per 1,000 units) per year.



Russia’s TVEL Fuel Company (TENEX for operations abroad) is the largest operator of nuclear enrichment centrifuges and absolute leader of world’s radioisotope market, possessing about 30,000 separative work units (SWU), which is almost half of the world’s total 65,000 SWUs. Russian centrifuges are also the most advanced and have higher output capacity than SWUs from rival companies in France, US or Japan.



Starting from 2009 Russia is supplying 7 and 8 Gen centrifuges to China.

The second-largest operator of uranium enrichment centrifuges after Rosatom is URENCO, a joint German, Dutch and UK enterprise operating 14,200 SWUs.

Rosatom is heavily investing in nuclear enrichment at the UIEP. In 2014, the corporation allocated 7.5 billion rubles (nearly $150 million), whereas for 2015-2019 Rosatom plans to spend on the UIEP no less than 34 billion rubles (about $667 million).

Why States Still Use Barrel Bombs

Smoke ascends after a Syrian military helicopter allegedly dropped a barrel bomb over the city of Daraya on Jan. 31.(FADI DIRANI/AFP/Getty Images) Summary Barrel bombs are not especially effective weapons. They are often poorly constructed; they fail to detonate more often than other devices constructed for a similar purpose; and their lack of precision means they can have a disproportionate effect on civilian populations. However, combatants continue to use barrel bombs in conflicts, including in recent and ongoing conflicts in Africa and the Middle East, and they are ideally suited to the requirements of resource-poor states. Analysis Barrel bombs are improvised devices that contain explosive filling and shrapnel packed into a container, often in a cylindrical shape such as a barrel. The devices continue to be dropped on towns all over Syria . Indeed, there have been several documented cases of their use in Iraq over the past months, and residents of the city of Mosul, which was re

Russia Looks East for New Oil Markets

Click to Enlarge In the final years of the Soviet Union, Soviet leader Mikhail Gorbachev began orienting his foreign policy toward Asia in response to a rising Japan. Putin has also piloted a much-touted pivot to Asia, coinciding with renewed U.S. interest in the area. A good expression of intent was Russia's hosting of the Asia-Pacific Economic Cooperation summit in 2012 in Vladivostok, near Russia's borders with China and North Korea. Although its efforts in Asia have been limited by more direct interests in Russia's periphery and in Europe, Moscow recently has been able to look more to the east. Part of this renewed interest involves finding new export markets for Russian hydrocarbons. Russia's economy relies on energy exports, particularly crude oil and natural gas exported via pipeline to the West. However, Western Europe is diversifying its energy sources as new supplies come online out of a desire to reduce its dependence on Russian energy supplies . This has

LONDON POLICE INDIRECTLY ENCOURAGE CRIMINALS TO ATTACK RUSSIAN DIPLOMATIC PROPERTY

ILLUSTRATIVE IMAGE A few days ago an unknown perpetrator trespassed on the territory of the Russian Trade Delegation in London, causing damage to the property and the vehicles belonging to the trade delegation , Russian Foreign Ministry Spokeswoman Maria Zakharova said during the September 12 press briefing. The diplomat revealed the response by the London police was discouraging. Police told that the case does not have any prospects and is likely to be closed. This was made despite the fact that the British law enforcement was provided with video surveillance tapes and detailed information shedding light on the incident. By this byehavior, British law inforcements indirectly encourage criminals to continue attacks on Russian diplomatic property in the UK. Zakharova’s statement on “Trespassing on the Russian Trade Mission premises in London” ( source ): During our briefings, we have repeatedly discussed compliance with the Vienna Convention on Diplomatic Relations, specif
