The safe operation of VVéR reactors has been discussed throughout the entire design process, taking account of the normative
documentation, including the international requirements (IAEA, EUR). After the first domestic normative document “Basic principles
for securing the safety of nuclear power plants” was approved in 1973, work began on the reconstruction of the first-generation
VVéR-440 power-generating units. The measures taken to increase safety concerned all types of reactors VVéR-440 and-1000.
Information on implementing these measures is presented.

It has been shown that the thermotensographic process in the layer of a copper dibromide solution in ethanol followed by catalytic
reduction of copper in a hydrogen current at 450°C can be used to obtain conducting lines. It has been established that in
an open liquid layer lines of isolated small crystals of copper are formed, and in a layer of a closed volume lines of intergrown
small crystals are formed due to the evaporation-convective intensification of the image. In the first case, the lines do
not conduct electric current, and in the second one their specific resistance is 4·103 times higher than in monolithic copper.

The article presents results of theoretical and experimental investigation of quasioptical multiplexer based on reflecting diffraction grating. Diffraction losses caused by reflection into mirror harmonic, and by angle divergence of wave beams are calculated. In an experimental multiplexer, wave beams with the frequencies 70 GHz and 79 GHz were mixed with power losses less than 1%. 相似文献

We have studied the effect of drawing conditions and process environment on the mechanical strength of microstructured optical fibers. The results indicate that, even at reduced drawing temperatures, high-strength fibers with few “weak” points can be produced provided that the walls of the holes in the preform are sufficiently clean. The effects of air humidity and different liquids in the holes on the strength of microstructured fibers are shown to be similar to those for standard fibers. 相似文献

The results of numerical simulation and experimental investigation of a prototype of a megawatt multifrequency gyrotron for controlled thermonuclear fusion facilities are presented. In experiments, the gyrotron has operated at six frequencies in the range 105–152 GHz with small diffraction losses in the internal quasi-optical system and a high Gaussian mode content in the output beam. 相似文献

1. | Alloy 01205 has satisfactory weldability in argon arc and resistance welding. The coefficient of hot cracking does not exceed 6% for the alloy with no more than 0.03% Mg, and the ultimate strength of the weld seam amounts to 50–70% of the ultimate strength of the base metal. |
2. | The strength of the weldments is highest after quenching from 532° in water and aging at 190° for 10 h. In this case the ductility drops almost 50%. |
