Behavior of the Water-Cooled Polycrystalline Diamond Plate at Extreme Densities of Laser Radiation
Physics of Wave Phenomena, 2018Resistance of a water-cooled polycrystalline diamond window is experimentally studied in the beam of the 10-kW fiber laser. The irradiated zones are 4 and 0.4 mm in diameter. It is shown that the transmitted beam is not distorted when the power density increases to 7 MW cm−2.

Chemico-Physical Causes of Radiation-Induced “Long Cell” Action Corrosion in Water Cooled Reactors
18th International Conference on Nuclear Engineering: Volume 5, 2010In the previous overview papers [1, 2], the author has identified that ‘long cell action’ corrosion plays a pivotal role in practically all unresolved corrosion issues, irrespective of reactor types and operation. In trying to confirm the existence of radiation-induced ‘long-cell’ action (macro) corrosion cell in the primary cooling system of LWRs, the

Abstract Positron annihilation spectroscopy (PAS) lifetime study was applied in the evaluation of the microstructure parameters and degradation processes of nuclear reactor pressure vessel (RPV) steel surveillance specimens. Study was oriented to the material investigation of Russian WWER-1000 steels (15Kh2MNFAA and 12Kh2N2MAA) with higher Ni content

Off-shore wind turbine is a new hot spot in the field of new energy. Due to the characteristics of high salt fog, high humidity and long sunshine time in the marine environment, the anti-corrosion performance of air radiator in the water cooling system of high-power wind turbine has higher requirements.

High power thyristor is the core switching device of pulse power source, which is an important component of electromagnetic launch (EML). So the reliability of high power thyristor directly affects the safe and reliable operation of EML. Semiconductor theoretical and experimental studies show that the electrical characteristics of thyristor are ...

The finite element method is used in the thermal and structural analyses of a 3-channel silicon-crystal monochromator in a wiggler x-ray beam. Liquid gallium and water are used as coolants. Liquid gallium is fed into the monochromator by an induction pump designed and built for this purpose at Argonne National Laboratory.

A non-water-cooled heat flux measurement system under concentrated solar radiation conditions
Solar Energy, 2002This paper presents a brief description of a direct heat flux measurement system to measure the concentrated solar power delivered by a heliostat field onto the flat aperture of solar central receiver prototypes. The main advantages of this device are the low measurement uncertainty and the non-requirement of water-cooling.

The problem of an emergency large-scale illumination with the high-intensity discharge (HID) lamp is the lack of radiation intensity because of inappropriate energy balance. Some researchers have researched that the radiation power depended on the arc temperature increases with increasing the current.

In this paper, a conceptual study and quantification of using a thermophotovoltaic system (TPV) to convert incident radiation on furnace panels to electrical energy is presented. In typical electric arc furnaces (EAF), a considerable amount of energy is wasted during the melting process, that is, steel enthalpy, off‐gas extraction, vessel cooling, slag
