... This paper reviews the current state of knowledge on attenuation of damage parameters in reactor pressure vessels (RPVs). There are two methods for evaluating attenuation of properties through a reactor pressure vessel wall. The first is by direct measurement of the change in mechanical...

... Thermal physical (thermal diffusivity and conductivity) and optical (attenuation, absorption and scattering) properties of alumina fiber insulation materials were measured. The measurements of apparent thermophysical properties are based on the method of heating of plate specimens at a constant...

... This paper describes the calculation of the attenuation of neutron dose through the steel pressure vessels of Magnox power plant operated by BNFL, Magnox Generation Division. These data are required for the assessment of the structural integrity of the plant. Detailed three-dimensional neutron...

... by a finite element technique showed that dynamic response is affected significantly by the presence of voids or disbonds. These results have direct implication in the interpretation of acousto-ultrasonic results. Through-transmission attenuation and a number of acousto-ultrasonic parameters for various...

... The displacements per atom (DPA) concept was adopted in Revision 2 to Regulatory Guide 1.99 to account for the through-wall attenuation of radiation damage in the reactor vessel beltline. Models have been developed that are capable of predicting atom displacements, but the overall effect...

... Experiments were conducted on pilot study spent tuffaceous ore and native soils to predict arsenic teachability and subsequent attenuation from a proposed spent ore pile at an Idaho gold mine. The experiments were patterned after the graded serial batch extraction tests developed by Houle...

..., and the ultrasonic properties (that is, the shear and longitudinal wave velocities and the attenuation) were measured as a function of strain. Finished flywheels were similarly tested at various stages during cyclic spin testing; in addition, the polar backscattering intensity as a function of fatigue cycle...

... ultrasonic methods with the theory of Fourier Transforms, a new technique has been developed which removes the preceding restriction. The theoretical and the experimental procedures are described in detail. The efficacy of the method is demonstrated for three disparate materials: (1) non-attenuative, non...

... the specimens are grouped and cause a significant attenuation of the neutron flux through each set of specimens. In the region containing the Charpy specimens, arranged in a 4 × 4 matrix, the attenuation is approximately 40%. To minimize the attenuation, the specimens were grouped so that each row or stack...
