FORMOSA-B: A BOILING WATER REACTOR IN-CORE FUEL MANAGEMENT OPTIMIZATION PACKAGE III

摘要

As part of the continuing development of the boiling water reactor in-core fuel management optimization code FORMOSA-B, the cold shutdown margin (SDM) con- Straint evaluator has been improved. The SDM evaluator In FORMOSA-B had been a first - order accurate Rayleigh Quotient variational technique. It was deemed unreliable For difficult perturbed loading patterns (LPs) and thus was Replaced by a high-fidelity, robust, computationally effi- Cient evaluator.
