A low temperature water-cooled radiation calorimeter for estimation of concentrated solar irradiance

Solar Energy, 2018
Abstract Radiation calorimeter is a device for assessment of the incident local concentrated solar irradiance (CSI) onto a receiver surface. This is required to evaluate the performance of a concentrated solar thermal system using, for instance a volumetric receiver, for applications. In this paper a low-temperature water cooled radiation calorimeter

Shield Penetrating Water Cooled Bus Ducts for Radiation Resistant Magnets at J-PARC

IEEE Transactions on Applied Superconductivity, 2008
The high intensity proton accelerator facility J-PARC is now in its final stage of construction. Soon intense primary proton beams will be slowly extracted to an experimental hall (HD-hall) and transported to a production target. Since the radiation level around the target will be very high, the beam line tunnel needs to be surrounded by 2.5 m-5 m ...

Thermal And Structural Analyses Of A Synchrotron Radiation X-Ray Monochromator With Liquid Gallium And Water Cooling

SPIE Proceedings, 1989
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.

Analysis on the anti-corrosion of air radiator in water cooling system for high-power offshore wind turbine

2020 4th International Conference on HVDC (HVDC), 2020
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.

Chemico-Physical Causes of Radiation-Induced “Long Cell” Action Corrosion in Water Cooled Reactors

18th International Conference on Nuclear Engineering: Volume 5, 2010
In 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
