The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is an 85 MW, light-water moderated, research reactor that operates at low temperature and high pressure. The HFIR is presently scheduled to convert from a high enriched uranium fuel (HEU) to a low enriched uranium fuel (LEU) in 2019. Due to cost constraints, not all experiments will be repeated for the LEU fuel ...

In this study, COMSOL®4.2a is used to model a microwave heating process in a TE10 rectangular waveguide. The sample consists of a small cylindrical Ca-alginate gel (D = 8 mm, H = 10 mm) inoculated with bacteria Escherichia Coli K12. The sample is placed along the microwave propagation direction into the waveguide. Maxwell’s equations and heat transfer are coupled to a microbial inactivation ...

Divertor is act as an exhaust for the nuclear fusion reactor. Main function of a divertor is to remove the heat flux from the plasma. Plasma facing components of the divertor are made up of Carbon (Graphite/CFC) and tungsten like materials. Hence these materials are exposed to the transient heat loads up to 10MW/m^2. Thermo mechanical behavior of Graphite test mock-up under the transient heat ...

Iodine absorber is a widely used purification equipment for purifying air in a nuclear power plant. In China, the common type is Ⅱ iodine absorber. Impregnated activated carbon is the main absorber within the iodine absorber. Because of the decays exothermic of radioactive iodine, heat is generated in the adsorption process. Carbon is a combustible material. Moreover, air is always supplied in ...

A two dimensional transient analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. Thermal and optical nonlinearity is induced during transient heating, since the response of weakly absorbing thin films depends on temperature. The heat ...

The paper investigates the hydrodynamic performance of a hierarchical parallel channel network for the objective of optimal thermal coupling to heat released in the adsorption processes, as in adsorption heat pumps. More specifically, the uniformity of the fluid flow over the network is improved by optimizing the topology of the manifold channels of the two hierarchical levels. For this purpose ...

Different types of technologies to recycle carbon fiber reinforced polymer (CFRP) waste have been studied, for example: pyrolysis, solvolysis and steam-thermolysis. The steam-thermolysis is a process that combines pyrolysis and superheated steam at atmospheric pressure to decompose the organic matrix of the composite. The waste is introduced into a bench-scale reactor heated at high temperatures ...
