Abstract
To cope with increasing spent fuel disposals and limited domestic spent fuel storages in Korea, the Korea Atomic Energy Research Institute has developed an advanced sodium-cooled fast reactor for TRU transmutation with an electricity output of 600 MWe (called the KALIMER-600 TRU burner). The design philosophy of the KALIMER-600 TRU burner concept is highly focused on inherent safety mechanisms, i.e., passive responses to abnormal and emergency conditions, and thereby minimizes the need for engineered safety systems. Accordingly, the main concern is on the sodium coolant void reactivity, a very important safety parameter of the KALIMER-600 TRU burner. This study was therefore performed to analyze the sodium void reactivity of the KALIMER-600 TRU burner to the finest resolution possible, e.g., contributions from any isotope in each core region. Such detailed analysis could be valuable and applicable to further optimization of the core passive safety characteristics against severe coolant voiding accident conditions.
Kurzfassung
Um dem Problem steigender Mengen abgebrannter Brennelemente und begrenzter eigener Lagermöglichkeiten in Korea gewachsen zu sein, hat das koreanische KAERI Forschungsinstitut einen fortgeschrittenen Natrium-gekühlten schnellen Reaktor für TRU Transmutation mit einer elektrischen Leistung von 600 MWe (den sogenannten KALIMER-600 TRU Brenner) entwickelt. Die Ausgestaltung des KALIMER-600 TRU Brennerkonzepts ist stark ausgerichtet auf inhärente Sicherheitsmechanismen und verringert dadurch die Notwendigkeit sicherheitstechnischer Anlagen. Dementsprechend liegt das Hauptinteresse bei der Void-Reaktivität des Natrium-Kühlmittels, einem wichtigen Sicherheitsparameter des KALIMER-600 TRU Brenners. Ziel dieser Studie war deshalb die Analyse der Natrium-Void-Reaktivität mit der bestmöglichen Auflösung. Eine solch detaillierte Analyse könnte auch für weitere Optimierungsmaßnahmen der passiven Sicherheitseigenschaften gegenüber schweren Kühlmittelverluststörfällen wichtig sein.
