Development of a core management tool for MYRRHA

MYRRHA is an advanced multi-purpose irradiation facility under development at SCK
- CEN in Mol, Belgium. In order to ensure an economical and safe operation of the reactor, an in-core fuel management tool is being developed within the project to address the loading pattern optimization problem. In the paper, the current version of the tool - its architecture and design, unique features, and the field of its application, are presented. In the second part of the paper, the tool's capabilities are demonstrated on simple MYRRHA in-core fuel management optimization problems.
