“…Due to the im por tance of both safety and op er ational points of views, ef forts have been made in the past to carry out stud ies for the in-core fuel man agement for var i ous test and re search re ac tors world wide. In this con text, a nu clear anal y sis and the fuel man agement code sys tem HANAFMS have been used for the anal y sis of the Ko rean high-flux ad vanced neu tron appli ca tion re search re ac tor (HANARO) [2].

MTR core loading pattern optimization using burnup dependent group constants

A diffusion theory based MTR fuel management methodology has been developed for finding superior core loading patterns at any stage for MTR systems, keeping track of burnup of individual fuel assemblies throughout their history. It is based on using burnup dependent group constants obtained by the WIMS-D/4 computer code for standard fuel elements and control fuel elements. This methodology has been implemented in a computer program named BFMTR, which carries out detailed five group diffusion theory calculations using the CITATION code as a subroutine. The core-wide spatial flux and power profiles thus obtained are used for calculating the peak-to-average power and flux-ratios along with the available excess reactivity of the system. The fuel manager can use the BFMTR code for loading pattern optimization for maximizing the excess reactivity, keeping the peak-to-average power as well as flux-ratio within constraints. The results obtained by the BFMTR code have been found to be in good agreement with the corresponding experimental values for the equilibrium core of the Pakistan Research Reactor-1
