Induction motors with conventional organic insulation are used at technological plants designed for recycling nuclear fuel waste of nuclear power stations. In the nuclear radiation environment, the service life of these asynchronous motors does not typically exceed 3-4 months as the winding insulation is destructed being exposed to nuclear radiation. This results in costs increase. To prolong the motor service life and reduce the costs, a valve-inductor-type motor is being developed for this application field due to a simple construction of the stator windings and the feasibility of using non-organic insulation.

By using modeling and simulation technology, motion simulation and structural analysis were carried out on hydraulic manipulators structure working in the radiation environment. The results of motion simulation can test the manipulators kinematics characteristic, and provide a basis for structural optimization design.Structural analysis could be used to validate manipulators s tructure is able to withstand the movement of stress, strain or not. Manipulators structure design can be properly improved by use of the structural analysis.

To predict the performance of nuclear fuels and materials, irradiated fuel plates must be characterized efficiently and accurately in highly radioactive environments. The characterization must take place remotely and work in settings largely inhospitable to modern digital instrumentation. Characterization techniques based on non-contacting laser sensing methods enable remote operation in a robust manner within a hot-cell environment. Laser characterization instrumentation can offer high spatial resolution and remain effective for scanning large areas. A laser shock (LS) system is currently being developed as a post-irradiation examination (PIE) technique in the hot fuel examination facility (HFEF) at the Idaho National Laboratory (INL). The laser shock technique will characterize material properties and failure loads/mechanisms in various composite components and materials such as plate fuel and next-generation fuel forms in high radiation areas. The laser shock-technique induces large amplitude shock waves to mechanically characterize interfaces such as the fuel–clad bond. As part of the laser shock system, a laser-based ultrasonic C-scan system will be used to detect and characterize debonding caused by the application of the laser shock. The laser shock system has been used to characterize the resulting bond strength within plate fuels which have been fabricated using different fabrication processes. The results of this study will be to select the fabrication process that provides the strongest interface.
