RESONANCE SELF-SHIELDING CALCULATION FOR PLATE-TYPE FUEL ASSEMBLIES

Resonance Self-shielding Method for Fuel Annular Subdivisions Using Quasi- 1D Slowing-down Solution

Monte Carlo calculation of epithermal neutron resonance self-shielding factors in foils of different materials.

Epithermal neutron resonance self-shielding factors in foils of materials used as activation detectors or as targets for radionuclide production have been calculated using the MCNP code. Two irradiation conditions have been considered: (a) foils immersed into an isotropic neutron flux and (b) foils submitted to a collimated neutron beam. The self-shielding factors, Gres(t), for gold, indium, ma...

Monte Carlo calculation of shielding parameters for fast neutrons in newly developed heavy concretes

Introduction: The role of radiotherapy as a part of cancer management increases every year around the world. Thus, Radiation protection in the design of radiotherapy rooms are of great importance.   Materials and Methods: In present study using Monte Carlo method, MCNPX code, fourteen types of developed high density concretes with densities ranging from 2.45 ...

Self-contained CLI Assemblies

High-level programming languages and bytecode-based virtual execution environments have become popular in software development. Bytecode-based runtimes extend embedded system by techniques to improve safety, help portability and interoperability. The ECMA/ISO Common Language Infrastructure (CLI) specifies a bytecodebased execution environment (Common Language Runtime) and a comprehensive class ...

Peptide Self-Assemblies for Drug Delivery.

Peptide amphiphiles (PAs) are novel engineered biomaterials able to self-assemble into supramolecular systems that have shown significant promise in drug delivery across the cell membane and across challenging biological barriers showing promise in the field of brain diseases, regenerative medicine and cancer. PAs are amino-acid block co-polymers, with a peptide backbone composed usually of 8-3...
