COAXIAL HIGH TEMPERATURE SUPERCONDUCTORS FOR LARGE ELECTROMAGNETIC SYSTEMS

Abstract. For large superconducting electromagnetic systems, for example, for controlled thermonuclear fusion devices, superconductors with currents up to several tens of kiloamperes in fields up to 15 T and at temperatures of 4,2–20 K are required. This paper presents the results of the analysis and development of one of the possible options for such a conductor based on the Russian superconducting tape of the S-Innovation company. It is shown that the conductors of the proposed design, which is relatively easy to manufacture, can be used in the winding of a toroidal field, since they provide the required parameters for future fusion devices, for example, for the planned tokamak of reactor technologies. At the same time, they should not degrade with rapid field changes, due to the aligned inductances of the layers and the uniform distribution of current in the tapes.

ALUMINIUM AND ITS ALLOYS FOR THE DOMESTIC CABLE INDUSTRY
V.V. Loparev, Cand. Sc. (Engineering), Head of Laboratory, JSC VNIIKP
Abstract. The article addresses the aluminium and aluminium alloy grades used by the domestic cable industry. The interrelation of the properties of aluminium alloys with their phase composition and heat treatment is shown. Extracts from the normative documents on the technical requirements for various grades of aluminium and its alloys, as well as for rod and wire made of them, are presented. The distinctive properties of aluminium alloys are indicated.
Key words: alloys, grades, chemical composition, impurities, heat treatment, phases, properties, technical requirements, rod, wire

Abstract. The results of comparative tests of selected halogen-free silane-crosslinkable compounds, including the study of thermal ageing of material samples, as well as a set of tests for resistance to environmental conditions under which cables are operated at nuclear power plants, are considered.
It was found that all four selected compounds meet the basic requirement for an extended service life of 60 years. It has also been shown that the materials retain satisfactory mechanical properties after exposure to both gamma radiation and the decontamination solution.
The analysis of the results of comparative tests of materials was carried out, on the basis of which the preferred areas of application of the compounds were determined and samples of cables were manufactured.
The results of tests of cables for resistance to the exposure of special influencing factors inside the NPP containment area (LOCA test) are presented, as part of a set of tests, based on the positive results of which R&D was accepted, the Technical specifications for power and control cables with extended service life for nuclear power plants were developed and approved.
Key words: extended service life, halogen-free silane-crosslinkable compounds, accelerated thermal ageing, cables for nuclear power plants, radiation resistance of polymers
