Production UEIP
Standard samples of isotope structure of uranium are the important component of the monitoring system of isotope structure of uranium at the enterprises of the branch making or processing enriched (impoverished) uranium.
The Ural electrochemical combine is the base organisation of the Ministry on SSISU and provides requirements of branch for these samples.
For creation SSISU on UEIP isotopes of uranium of high isotope cleanliness (uranium-238 with cleanliness of 99,9999 %, uranium-235 with cleanliness of 99,99 %) are received. Isotopes of uranium of so high cleanliness in industrial conditions are made only on UEIP.
Manufacturing SSISU and their delivery on UEIP occupy the specialised division incorporating technological, chemical and mass spectrometer sites, equipped with modern precision equipment.
Offered customers in branch and behind its limits system SOISU includes more than 110 types WITH, maintenances of uranium-235 covering all range, beginning from pure uranium-238 and including pure uranium-235. It provides any inquiries of consumers. Standard samples by request of consumers are delivered as in the form of gaseous geksaftorid uranium, flew and in the form of a powder zakisi-okisi uranium.
Accuracy of certification of isotope structure SOISU not only provides requirements of the technological control of a course of processes of enrichment of uranium, but also definition of isotope structure of a commodity output of the enterprises at level demanded by the international specifications.
Deliveries of standard samples of isotope uranium to the Russian customers are made directly under contracts with UEIP. To foreign customers SSISU are delivered through joint-stock company "Tehsnabeksport".
GSO STRUCTURE OF PRODUCTION OF THE NUCLEAR INDUSTRY
STANDARD SAMPLES OF ISOTOPE STRUCTURE OF URANIUM (SSISU) | Set from 30 types; numbers GSO are resulted more low. |
APPOINTMENT - metrological certification of techniques of performance of measurements, the control of metrological characteristics at test of mass spectrometers, checking of mass spectrometers, the control of errors of techniques of performance of measurements by a mass spectrometry method.
The DESCRIPTION - GSO are delivered in the gaseous form (geksaftorid uranium) in metal samplers and in the form of a disperse material (zakis-okis uranium) in glass bottles. The form and weight GSO makes a reservation the customer by delivery.
The CERTIFIED CHARACTERISTICS - nuclear shares of isotopes uranium-234, uranium-235, uranium-236, uranium-238, and also the isotope relation uranium-235/uranium-238.
