Geometrical aspects of alpha dose rates from UO2 based fuels
نویسندگان
چکیده
Models for calculating dose rates of spherical particles as well in fuel cracks are important radionuclide source term estimations. Dose from UO2 based fuels were calculated planar, spherical, and crack geometries. The escape probability ?-particles was derived a continuous equation. rate increased with increasing radius due to the decreasing relative volume surrounding water layer. model produced probabilities that closely predicted by theoretical derivation. It shown filled width smaller than range an ?-particle led dissolution lower per unit surface area.

Radiation dose aspects in the handling of emerging nuclear fuels.
The occupational annual dose levels, encountered at fabrication of emerging nuclear fuels, have been studied. Emerging fuels for the single and multiple recycling of Pu and MA have resulted in considerably higher gamma and neutron doses in comparison with commercial fuels. The occupational dose limit is exceeded at fabrication by a single fuel rod in all fuel cases with (241)Am and Cm isotopes ...

In this research, we aim to clarify the relationship between the structural distortion due to doping and the superconductivity existence in the FeAs4 structure. For this, we have prepared polycrystalline of NdFeAsO0.8F0.2, NdFeAs0.95Sb0.05O0.8F0.2 and Nd0.99Ca0.01FeAsO0.8F0.2 samples by one-step solid state reaction method. The structural and electrical properties of the samples were characteri...
متن کاملGeometrical aspects of protein folding
These lectures will address two questions. Is there a simple variational principle underlying the existence of secondary motifs in the native state of proteins? Is there a general approach which can qualitatively capture the salient features of the folding process and which may be useful for interpreting and guiding experiments? Here, we present three different approaches to the first question,...

A twistor Cech cohomological characterization of mixed frequency zero rest-mass elds is developed. Using a Cech form of the cup product we derive an expression for the symplectic product of two real mixed frequency scalar elds in terms of a single vertex diagram. An expression for the frequency splitting complex structure of quantum eld theory is derived, and presented by its action on a mixed ...
