The stress analysis and stress evaluates of γ-spectrometer-probe station

γ-Spectrometer -Probe Station is used for monitoring the reactor core fuel assemblies. The structural framework of this equipment possessed the massive lead bricks and linear supports. The article uses the finite element method and the conversion density method for processing lead bricks. Using shell element makes the analysis of liberating shape. The rigid supports are proposed and the stacking of the lead-bricks is improved. Meanwhile, the optimized design has been conducted for the equipment component. Using the computed results, the stress evaluate of the equipment is strictly made according to the ASME codes and standards. (author)
