Comparison of calculated results with NTD measured data for establishment of burned core model for Monte Carlo simulation of HANARO reactor

摘要

The modeling method to establish a depleted-core model for the Monte Carlo simulation was verified by comparing the analysis results with the neutron flux distribution obtained by a zirconium activation method and a reaction rate of Si-30(n, gamma) Si-31 obtained using a resistivity measurement method. First, the modeling method used to build the depleted-core model using the HANAFMS core management system is explained. Calculation and measurement methods are also described including the reactor condition, irradiation device, and data treatment methodology. Finally, the viability of the proposed modeling method was discussed through a comparison of the calculated and measured results.
