Nuclear power is nowadays in the front rank as regards helping to meet the growing worldwide energy demand while avoiding an excessive increase in greenhouse gas emissions. However, the operating nuclear power plants are mainly thermal-neutron reactors and ...
Fragmented solid targets made of either fluidised tungsten powder or static pebble bed of tungsten spheres, have been long proposed and are being studied as an alternative configuration towards high-power (>1 MW of beam power) target systems, suitable for ...
The behavior of a pile subjected to thermo-mechanical loadings was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. A pile situated in a building under construction was equipped with a chann ...
The competition of two Rhodocyclaceae-affiliated bacterial populations was assessed during the formation and maturation of aerobic granular sludge in two different types of anaerobic-aerobic sequencing batch reactors. Zoogloea spp. (57%) were predominant i ...
A new measurement technique has been developed to determine fission rates in burnt fuel following re-irradiation in a zero-power research reactor The development has been made in the frame of the LIFE@PROTEUS program at the Paul Scherrer Institute which ai ...
Solar power is nowadays a promising solution to the energy supply problem, at least in the countries of the sunbelt or for solutions of delocalized production as the Desertec project . Due to the transient nature of solar irradiance, some storage technique ...
The utility of molten salts was demonstrated in the synthesis of the 1st family of mesoporous salt-inclusion solids featuring [V4O16] and [V5O17] polyoxovanadate (POV) units interlinked by As5+ cations, Cs3.5Na1.47(V5O9)(AsO4)2Cl2.33, Cs3.88Na0.12(V4.6O8.6 ...
The operating temperature range of molten carbonate fuel cells (MCFCs) is about 925-955K. An input gas temperature of at least 855 K is necessary to guarantee good ionic conduction inside the cells. Maximum local temperatures higher than 960 K should be av ...
In the pressure infiltration of metal matrix composites, molten metal is injected under external pressure into a porous preform of the reinforcing material. Equilibrium capillary parameters characterizing wetting for this process are summarized in plots of ...
The Supercritical-Water-Cooled Reactor (SCWR) is the Generation IV reactor concept most closely related to current light water reactors (LWRs). The SCWR builds on the vast experience with today's LWRs and supercritical coal-fired power plants. Water at sup ...
