BALO-BWR Assembly Lattice Optimization

摘要

BALO is a program package for BWR assembly lattice optimization, and it has three major components: a BWR fast lattice simulator (FLS), a BWR lattice optimizer (OPTM), and a BWR assembly lattice interactive and automated design tool (ALAADIN). The current version of BALO has greatly reduced the time required for lattice design iteration with good accuracy over the entire design range, Kinf. within 0.0005, and MPP (maximum pin power factor) within 1% compared with CASMO4. This paper summarizes the newly developed BWR lattice perturbation theory for FLS, the optimization algorithms used in OPTM, and the BALO test results.
