Measurement of PDP Drums Evaluate Program Isotopic

چکیده
Measurement of nonhomogeneous special nuclear material using passive gamma techniques is difficult because it is not practical to develop standards with the characteristics of the samples. Each sample is different. And the samples must be measured nondestructively. Modeling methods must be used. The modeling methods assume homogenous distribution of radioactive and matrix material within the container. In practice, the activity must penetrate localization matrix attenuation or attenuation by the heavy material itself. In addition, geometry errors are introduced when the activity is localized in one spot.

Prediction of long-term slake durability of clay-bearing rocks
A research program was conducted on different clay-bearing rocks selected from the Ilam, Sarpol-e Zahab and Tajarak regions (Iran) to predict their slaking characteristics. The new durability apparatus (nested mesh drums) separates disintegrated particles varying from > 25.4 to < 2 mm as the drums were rotated. On the basis of the particle size distribution, the disintegration ratio (DR) was us...
متن کاملHPGe and Scintillation Detectors Comparisons on Waste Drums Radioactivity Measurement
Two measurement systems, one being comprised of three HPGe detectors and the other being a 4π measurement system of the assembly of 10 sets of scintillation detectors, were compared for their measurement performance in operations of radioactive waste drum radioactivity measurement and clearance and release operation of decommissioning. The system features of the former were high costs, capable ...
متن کاملA timed colored Petri nets modeling for dynamic workflow in product development process
Product development process (PDP) is one of the most important business processes for enterprises but it has difficulty in workflow management because of the uncertain and dynamic characteristics. Thus, even though there have been many workflow modeling and management methods, they have limitations to deal with the special characteristics of PDP. We define PWF-nets based on timed colored Petri ...
متن کاملMaterial Flow in Rotary Drums
The experimental investigation of material flow in rotary drums is studied. An equipment in the size of pilot-scale was used to collect experimental data for investigation of validity of the conventional steady-state model of material flow in rotary drums. Also, the transient data of the time required for material movement in the empty drum up to any specified cross section are also reported. T...
