The electric and thermal conductivity of the aluminum alloys AMG-2 and SAV-1, which are used to fabricate the fuel elements of the fuel assemblies of a nuclear reactor, was investigated in the range 290–490 K. The Debye temperature was calculated and the contribution of the electronic and lattice components to the thermal conductivity of the alloys was determined. It is shown on the basis of an analysis...
The thermal conductivity of the aluminum structural alloy SAV-1 used for fuel-element cladding in the fuel assemblies of a nuclear reactor is studied. It is determined that the behavior of the thermal conductivity in the range 290–490 K is nonlinear. The Debye temperature is calculated and the phonon-phonon contribution to the total thermal conductivity of the alloy is determined. It is shown on the...
New technology is offered for measuring and control of light intensity. In the proposed method the phenomenon of acoustical activity and Bragg light diffraction on hypersonic waves in ferroelectric crystal LiNbO3 is used. Control of light intensity can be realized by transference of crystal or by modification of generator frequency by which the transverse acoustic wave is excited. The change of light...
