Abstract
This paper illustrates the neutronic and thermal hydraulic models that were implemented in the nuclear research reactor simulator based on LabVIEW. It also describes the system and transient analysis of the simulator that takes into consideration the temperature effects and poisoning. This simulator is designed to be a multi-purpose in which the operator could understand the effects of the input parameters on the reactor. A designer can study different solutions for virtual reactor accident scenarios. The main features of the simulator are the flexibility to design and maintain the interface and the ability to redesign and remodel the reactor core engine. The developed reactor simulator permits to acquire hands-on the experience of the physics and technology of nuclear reactors including reactivity control, thermodynamics, technology design and safety system design. This simulator can be easily customizable and upgradable and new opportunities for collaboration between academic groups could be conducted.
Kurzfassung
In diesem Beitrag werden die neutronischen und thermohydraulischen Modelle, die im LabVIEW-basierten Simulator für Forschungsreaktoren implementiert wurden, vorgestellt. Das System und die Transientenanalyse des Simulators werden beschrieben. Dieser Simulator ist so zweckmäßig gestaltet, so dass der Reaktor-Betriebspersonal die Wirkung der Inputparameter auf das Reaktorverhalten gut verstehen kann. Auf diese Weise können verschiedene Lösungen virtueller Reaktorstörfallszenarien untersucht werden. Ein Hauptmerkmal des Simulators sind die flexiblen Ausgestaltungsmöglichkeiten und Modellierungen des Reaktors. Der Simulator ermöglicht es, Physik und Technologie des Reaktors einschließlich Reaktivitätskontrolle, Thermodynamik, Ausgestaltung technischer und Sicherheits-relevanter Aspekte durch praktische Erfahrung zu verstehen. Der Simulator lässt sich leicht anpassen und aufrüsten und kann so zur Verbesserung der Zusammenarbeit zwischen akademischen Gruppen beitragen.
