Abstract
The notion of in-core fuel management (ICFM) involves decision making in respect of the specific arrangement of fuel assemblies in a nuclear reactor core. This arrangement, referred to as a reload configuration, influences the efficiency and effectiveness of fuel usage in a reactor. A decision support system (DSS) may assist nuclear reactor operators in improving the quality of their reload configuration designs. In this paper, a generic optimisation-based DSS framework is proposed for multi-objective ICFM, with the intention of serving as a high-level formalisation of a computerised tool that can assist reactor operators in their complex ICFM decisions.
Highlights
During the operation of a nuclear reactor, depleted fuel assemblies are periodically replaced with fresh ones in order to sustain the fission chain reaction occurring in the reactor core
The conceptualisation of the framework is novel in the sense that, to the best of our knowledge, there are no other decision support frameworks with the aforementioned application scope in the in-core fuel management (ICFM) literature
A framework for an optimisation-based decision support system (DSS) in the context of multiobjective in-core fuel management (MICFM) was proposed in this paper

Author affiliations 1 Radiation and Reactor Theory, The South African Nuclear Energy Corporation SOC Ltd, South Africa. The notion of in-core fuel management (ICFM) involves decision making in respect of the specific arrangement of fuel assemblies in a nuclear reactor core. This arrangement, referred to as a reload configuration, influences the efficiency and effectiveness of fuel usage in a reactor. A decision support system (DSS) may assist nuclear reactor operators in improving the quality of their reload configuration designs. ‘n Besluitsteunstelsel (BSS) mag kernreaktor-operateurs help om die kwaliteit van hul herlaaikonfigurasie-ontwerpe te verbeter. In hierdie artikel word ‘n generiese optimeringsgebaseerde BSS vir veeldoelige BKBB voorgestel wat ten doel het om as ‘n hoë-vlak formalisering van ‘n gerekenariseerde toepassing te dien wat operateurs kan bystaan met hul komplekse BKBB-verwante besluite
