About 70 to 75% of the energy consumed by the elements of transmit modules (TM) for active phased antenna arrays (APAA) is converted into heat. This heat, if dissipated inefficiently, can cause the element base to overheat, thus reducing the reliability of the radar. The task of ensuring the normal thermal regime of TMs for APAAs is complicated by the large-scale integration of electronic components inside the TMs.

For lighting in the world, 19 to 22% of the generated electricity is consumed. The introduction of energy-saving technologies in lighting systems will provide significant energy savings and improve the environmental state by reducing emissions of thermal power plants in the environment. One way to save energy in lighting is to switch to LED lighting. Light output of LED light sources is 10 times higher than the light output of incandescent lamps and 2 times - compact fluorescent lamps containing mercury.

Up to 30% of the produced electricity is being spent on the lighting in Ukraine. Therefore, the problem of energy saving in lighting stands very seriously. Introduction of energy-saving technologies in the internal lighting systems will provide significant energy savings and improve the ecological condition by reducing atmospheric discharges of thermal power plants.

Formulation and conduct of this work due to the urgent need to increase the security level of nuclear power equipment operations. The use of passive systems that operate mainly due to natural forces and phenomena and which include the heat transfer systems of evaporating-condensing type (ЕСT) will dispense with equipment at work which may refuse, reduce dependence on operator's actions during transients and accidents.
