Key takeaways

  • Techsnabexport belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Techsnabexport to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Techsnabexport from memory before moving on to harder problems.

Reference excerpt

Techsnabexport (Russian: АО "Техснабэкспорт"), internationally known as TENEX, is an overseas trading company owned by Russian state-owned company Rosatom. Techsnabexport is an exporter of enriched uranium and a supplier of nuclear fuel cycle products.

History

In 1949, a Soviet technology export enterprise Technoexport, under the Soviet Union's Foreign Trade Ministry, created a special working group to supply equipment to uranium mines in the Eastern Bloc. In 1952, the working group was used as a platform to create the Technical Supply Office of Technoexport, whose customers included the Soviet-German joint venture Wismuth in East Germany, the Jáchymov mines in Czechoslovakia, Quartzite in Romania, Kowarskie Kopalnie in Poland, and the Soviet-Bulgarian Mining Company. In 1955, Technoexport was reorganized and the Technical Supply Office was transferred to an export enterprise called Mashinoexport. On 17 July 1963, Techsnabexport was established as an export and import bureau. It supplied equipment to uranium mining companies in Eastern Europe and managed clearing payments for uranium imports. The company was commissioned to export and import rare earth elements, rare and refractory metals, radioactive and stable isotopes, ionizing radiation sources, control and measuring equipment, and accelerator and X-ray equipment. In 1975, Techsnabexport was reorganized as an independent company. Its main activity was providing uranium enrichment services for foreign customers. The first contract for the supply of uranium enrichment services was signed in May 1971 with the Atomic Energy Commission of France, launching Russian uranium products to European and global markets. In the 1970 and 1980s, contracts were signed with Italy, West Germany, Sweden, Spain, Finland, the United Kingdom, Belgium, and South Korea. In 1988, Techsnabexport was transferred to the Soviet Union's Ministry of Medium Machine-Building (predecessor of Rosatom). In 2007, it was integrated with Atomenergoprom, 100% of shares of which belong to Rosatom. During the period of radical market reforms in the Russian nuclear industry between 2002 and 2007, TENEX acquired and consolidated assets in the uranium mining, engineering, and chemical sectors. Later, non-core assets were transferred to other subsidiaries of Rosatom, such as TVEL (acquired the Russian Gas Centrifuge holding), holding company Composite (acquired the research and manufacturing complex UMATEX Group), ARMZ Uranium Holding (acquired the Russia-based and foreign uranium mining assets), mechanical engineering and chemical sector companies. In October 1992, the Russian Federal Agency on Atomic Energy and the United States Department of Commerce signed the Agreement Suspending the Anti-dumping Investigation on Uranium from the Russian Federation (Suspension Agreement). By the terms of the agreement, the investigation that was initiated in 1990s by the US natural uranium producers was frozen. The suspension agreement terms allowed for carrying out commercial supplies of negligible volumes of enriched uranium within the agreed quotas through 2002. In 1994, TENEX signed a contract with United States Enrichment Corporation to provide supplies of LEU downblended from 500 tons of highly enriched uranium extracted from Russian nuclear weapons to the US until the end of 2013. In 2008, Rosatom and the US Department of Commerce signed an amendment to the suspension agreement concerning uranium supplies from Russia, which was developed upon the initiative and with the participation of TENEX. It established necessary legal conditions for Russian uranium products to commercially enter the US market that had been closed to it during the preceding decade. In 2008, TENEX signed contracts with China National Nuclear Corporation to provide technical support in the construction of the fourth stage of the gas centrifuge plant in China, as well as for uranium enrichment services and supplies of enriched uranium product from 2010 to 2020. In 2012, TENEX signed a contract with Emirates Nuclear Energy Corporation on low-enrichment uranium supplies from 2015 to 2029 for the Barakah nuclear power plant. Since 2016, TENEX has been cooperating with Japanese partners on recovery after the Fukushima Daiichi Nuclear Power Plant accident. After a competitive tender was carried out in 2017 by the Mitsubishi Research Institute, TENEX and FSUE RosRAO worked on the creation of a neutron detector to search and identify fuel debris fragments inside the reactor space. In February 2017, TENEX was appointed the sole organization authorized to conclude foreign trade deals related to import to Russia of irradiated fuel assemblies from nuclear power reactors. In 2017, TENEX was authorized by Rosatom to move low-enriched uranium though the territory of the Russian Federation within the IAEA LEU Bank creation in Kazakhstan. In February 2018, TENEX and FSUE RosRAO, the V. G. Khlopin Radium Institute and SSC RIAR, was chosen for a project to develop technologies for analyzing the ageing properties of fuel debris subsidized by the Japanese government. Companies will study the samples of corium and "lava" generated by the Chernobyl Nuclear Power Plant accident, and will manufacture model samples of Fukushima Daiichi NPP fuel debris to develop a prediction model for the changes of corium properties with the aim of using it for post-accident clean-up at Fukushima Daiichi NPP. In 2019, after completing research on predicting changes in corium properties during aging, TENEX was selected as the executor of the second project on this topic.

Operations TENEX develops and supplies SNF storage and transportation systems, supplies equipment for RW management, builds infrastructure facilities for SNF management at the customer's premises, and reprocesses uranium-containing materials. The company also provides transportation and logistics services, and is developing new lines of business. In 2019, TENEX concluded 28 deals with eighteen customers from eight countries, including additions to the existing contracts. The value of the deals was about $3 billion.

Worked examples

Example 1 — a first encounter with Techsnabexport

Start with the simplest possible case. Write down what Techsnabexport claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Techsnabexport before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Techsnabexport ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Techsnabexport

In research
Techsnabexport appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Techsnabexport in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Techsnabexport is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 establishments in the Soviet Union, Companies based in Moscow, Companies of the Soviet Union, so understanding it makes those chapters shorter.
In everyday life
Look for Techsnabexport outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
