Abstract
Modern technology for the processing of spent fuel assemblies (SFA) and radioactive waste (RW) is utilized in radiation protection cells. Under the conditions of exposure to high radiation fields, there is an intense destruction of various assemblies of actuators made of organic materials, including insulation of motor windings, which leads to frequent equipment failures requiring repair or replacement. Within the limits of the existing need, a project is being developed, with the purpose of creation of a radiation-resistant asynchronous electric motor with ceramic insulation for operation in. The proposed technical solutions make possible to increase the service life of the engine operating under the influence of radiation fields in radiation protection chambers by 4-5 times. Operation under an extreme condition requires an assessment of the engine itself. Considering a non-standard cooling system is of crucial importance for such projects.
Highlights
The departments “Electric Machines” and “Rare Metals and Nanomaterials” of UrFU develop asynchronous motors capable of operating in technological installations for various purposes under the extreme conditions of exposure to radiation fields and high temperatures or in chemically aggressive environment.One of the perspective directions is the development of an asynchronous motor with an asymmetric magnetic core (AMAMC).2

The method is based on suppressing the EMF of the higher harmonics of the field in the rotor rods of an induction motor by dividing the stator core along two equal parts and the relative displacement of their phase zones by an angle corresponding to the pole division of the field harmonics from which rotor rods must be suppressed
Summary
The departments “Electric Machines” and “Rare Metals and Nanomaterials” of UrFU develop asynchronous motors capable of operating in technological installations for various purposes under the extreme conditions of exposure to radiation fields and high temperatures or in chemically aggressive environment. The use of the new design of ADAM with IP 68 protection and water cooling required the adjustment of the original electromagnetic calculation methods, including the methods for calculating the magnetic circuit, no-load current, and stator winding scattering parameters developed by the Electric Machines Department for asynchronous motors with an asymmetric magnetic circuit, and studying thermal engine condition. In assessing the thermal state of the engine, the dependence of the heat transfer coefficient on the cooling water flow rate, found as a result of the calculation of the liquid cooler by a numerical method (see Figure 4) based on the developed hull design, was used.
