Argon-41 can be a very good gaseous radiotracer for industrial applications if a sufficient amount of activity is produced from the reactor. The common procedures for preparing Argon-41 by irradiation of a quartz ampoule containing compressed argon gas give such low efficiency that the produced activity is not sufficient to compensate the $^{41}$Ar decay during transportation to the...

Background of the study:
Gas-solid conical fluidized bed are used for several application like drying, food processing, granulation, combustion, gasification, coating of nuclear fuel particles, crystallization, catalytic cracking, sulphide ores sedimentation and particle classification etc. The design parameter for mentioned applications depends on the bed behaviour completely. However,...

Tracer studies are used to characterize the porous media for flow paths of different phases, pore volume and flow surface area in reactors or oil reservoirs. The stagnant or dead pore volume interacts with the tracer leading to a tailing effect in the tracer breakthrough curve. Therefore, the effluent concentration profile from a single tracer test is not sufficient to characterize the porous...

Convective boiling flows are found in nuclear reactors and are subject of numerous experimental and theoretical studies. The thermal hydraulics of the nuclear reactor, especially boiling water reactor (BWR), is affected by the complexities of two-phase flow around the rods driven by a vertically distributed heat flux in the rods. One of the main challenges in operating this kind of a reactor...

This work has been performed using the fourth-generation-like
industrial computed tomography developed at the IPEN, constituted with
$70$ NaI(Tl) $25.4~\mathrm{mm}\times50.8~\mathrm{mm}$ (diameter
$\times$ length) and a bubble column for industrial process was
evaluated. The column is a Perspex glass cylindrical tube of $80$ mm
internal diameter, $100$ mm external diameter and $1400$ mm...
