COMPOSITE REFLECTOR

Hie effect of composite reflectors of steel and water on the reactivity of single cylinders of aqueous solution of low-enriched uranium has been studied. Ihe results are applicable in the evaluation of the nuclear criticality safety shipping containers and provide bases for the verification Of calculatlonal models.

The second example shows results obtained with an angle beam probe for transverse waves in coarse grained grey cast iron. Two commercially available probes are compared the composite design SWK 60-2 and the standard design SWB 60-2. The reflector in this example is a side-drilled hole of 5 mm diameter. The A-scans displayed below in Fig. 5 and 6 show that the composite probe has a higher sensitivity by 12 dB and that the signal to noise ratio is improved by more than 6 dB.

Resins are used in electromc/electncal applications (connectors, circuit boards that are vapor and wave solderable, microwave transparent radomes, integrated circuit chip carriers, miniature switches, explosion proof enclosures, lamp reflectors, and high-precision fiber optic components). Polyetherimide is used for medical components (hat require all forms of sterilization. Other uses are found in the transportation field, dual-ovenable cookware, as well as bearings, fasteners, and advanced composites. 

The axial distribution was measured in early experiments in the HFIR. The data were very well fit by the usual chopped cosine distribution with a small amount of reflector peaking (Fig. 4). We generally calculate the target compositions at... 

To find the density of neutron flow in the fuel, information is required on the capacity, energy output, and operation mode of RC their dimensions material composition of RC and the reflector the geometry and nmnber of fuel rods and fuel assemblies (FA) the BA and CR the coolant type and its thermodynamic parameters. 

The properties of upper-mantle seismic reflectors, especially the observed lateral variations in the seismological properties of the mantle transition zone, indicate that the upper mantle possesses a peridotite composition, approaching... 

Physical properties provide a lithological and geotechnical description of the sediment. Questions concerning the composition of a depositional regime, slope stability or nature of seismic reflectors are of particular interest within this context. Parameters like P- and S-wave velocity and attenuation, elastic moduli, wet bulk density and porosity contribute to their solution.
