Effective multi-group cross section calculation method for FCM fuel based on improved disadvantage factor method

AbstractA rapid spherical harmonic calculation method is used for the design of Nuclear Magnetic Resonance shim coils. The aim is to design each shim such that it generates a field described purely by a single spherical harmonic. By applying simulated annealing techniques, coil arrangements are produced through the optimal positioning of current-carrying circular arc conductors of rectangular cross-section. This involves minimizing the undesirable harmonics in relation to a target harmonic. The design method is flexible enough to be applied for the production of coil arrangements that generate fields consisting significantly of either zonal or tesseral harmonics. Results are presented for several coil designs which generate tesseral harmonics of degree one.

The aim of this paper is to provide a solution for easy calculations of reinforced concrete with biaxial bending cross-section. The paper presents in an orderly manner basic definitions related to the discussed topics, to the extent necessary to understand the discussed issues. As a result of the computational analysis dozens of sections with biaxial bending, there was developed a table and a chart containing the correction factor for bending moments, allowing to obtain the correct bearing capacity of cross-section, subjected to biaxial bending. This work presents proposition for a new, own calculation method of such cross-section. Calculations were made according to PN-EN 1992-1-1:2008, Eurocode 2, Design of concrete structures. Part 1-1: General rules and rules for buildings, using algorithms based on simplified methods. According to carried out calculations, cross-section dimensioning compressed with biaxial eccentricities separately on each side and values of bending moments should be increased to maintain cross-section's bearing capacity. The coefficient K scaling moments was determined as a function of eccentricity ey. With the increase of eccentricity, the coefficient K decreases.

Based on meeting the requirement of ground bearing capacity, the allowable range of anti-overturning safety factor is derived. The relative parameters are expressed with base width and the relation graphs of conversion factor are presented, and then can design the cross-section of retaining wall directly by combining the stability requirement of anti-sliding. The calculated result shows that this method makes the design simple and reliable. It may be a reference for engineers.
