A Critical Heat Generation for Safe Nuclear Fuels after a LOCA

Validation of ORIGEN-S Decay Heat Predictions for LOCA Analysis

Recent developments in the nuclear data libraries used by the ORIGEN-S isotope generation and depletion code have enabled the extension of the code to accurately predict the delayed energy release rates from nuclear decay (decay heat) at very short cooling times of interest to reactor accident analysis. Historically this time domain has required integral methods, such as the ANS5.1 decay heat s...

Mechanism Generation for Hydrocarbon Fuels

ion The linear alkanes, as most simple components, provide the fundamentals of fuel modeling in the case of more complicated components (alkenes, aromatics, polycyclic aromatic hydrocarbons, etc.). Meanwhile n-alkanes or blending of n-alkanes are by far the best studied class of compounds for which reliable, detailed chemical kinetic models for combustion exist and supposed to be the suitable s...

Transient Three-Dimensional Thermal Analysis of a Slab with internal heat generation and heated by a Point Moving Heat Source

In this work, analysis of transient three-dimensional heat transfer in a slab with internal heat generation and heated by a point moving heat source along its axis is carried out using integral transforms methods. The heat input into slab or workpiece by the moving heat source is considered in the model. From the results, it was established that the temperature of the material during the heat t...

I-4: A Simple and Safe Technique for Varicocele Surgery

s:2127:"Varicocele is the most common pathologic finding in men in infertility study programs and is the most treatable cause of male infertility. Its correction is performed by different surgical techniques, none of which is yet acknowledged as the "gold standard." Some of them, especially the microsurgical ones, are very time consuming and thus expensive; furthermore, all varicocele surgery i...
