Abstract The isotope ratio method (IRM) is a technique used for estimating the energy production in fission reactor by measuring ratios nonfuel components. This has been successfully demonstrated on estimation of cumulative as well plutonium graphite-moderated and light-water-moderated reactors nonproliferation purposes. In this paper, IRM was to estimate neutron fluence Zr-2.5Nb materials irra...

Traditionally, Internet has offered multimedia services independently of the services offered by companies associated to Telco (companies that traditionally offer telephony and associated services). In the last years, the technical community has assumed that the convergence of both worlds is a fact; however, there are many barriers to be removed. On one hand the emergence of cloud computing tec...

W artykule podjęto problem opracowania wydajnej technologii wzbogacania rud hematytu. Celem badań jest zbadanie właściwości procesowych słabo rozsianych hematytu Ukrainy, z uwzględnieniem ich mineralogicznych, opracowanie schematów oraz ocena skuteczności separacji minerałów podczas grawitacyjnego, magnetycznego i metody flotacji.Badania przeprowadzono na próbce krzyworoskiego zagłębia żelaza U...

Best estimate plus uncertainty is the leading methodology to validate existing safety margins. It remains a challenge develop and license these approaches, in part due high dimensionality of system codes. Uncertainty quantification an active area research appropriate methods for propagating uncertainties, offering greater scientific reason, reduction minimising reliance on expert judgement. Inv...

In the conversion of fuel in the Tehran Research Reactor core from Highly- Enriched Uraniutn to Low-Enriched Uranium fuel neutronics analysis, thermal hydraulic calculations and kinetic performance of the core have to be studied. In this study, static and dynamic core performance for HEU and LEU fuels were investigated. In static conditions, two groups of neutron flux distributions in axia...

The study explored the socio-demographic factors that anchor career choice among psychology students at the University of Venda in South Africa. Ex post facto research design was employed. A questionnaire was used to collect data. The chi-square and t-test were used to test differences in the data profiles. Response frequencies and corresponding percentages were calculated. Results showed that ...
