Abstract
TRISO-wrapped fuel particle failure is a function of local temperature. The spherical symmetry and hence central temperature peak in PBM-type reactor fuel pebbles can lead to considerably higher failure rates at the center of the pebbles. The so-called “wallpaper fuel” concept has been shown to be a viable solution to this issue. In this paper, the neutronic aspects of this modification were studied using MCNP. According to the obtained results, the inclusion of a central fuel-free zone could lead to a more reactive system with lower actinide production while damping the temperature response of the reactor.
Kurzfassung
Der Bruch von TRISO-beschichteten Brennstoffpartikel ist eine Funktion der lokalen Temperatur. Die sphärische Symmetrie und damit der zentrale Temperaturpeak der Brennstoffkugeln vom Typ PBM kann zu erheblich höheren Bruchraten im Zentrum der Kugeln führen. Das Konzept des sogenannten „Tapeten“-Brennstoffdesign ist da eine praktikable Lösung. In diesem Beitrag wird das Neutronenverhalten dieser Modifikation mit Hilfe des MCNP-Codes untersucht. Die Ergebnisse zeigen, dass die Inklusion einer zentralen Brennstoff-freien Zone zu einem reaktiveren Systems führen könnte mit niedrigerer Aktiniden-Produktion und vermindertem Temperaturverhalten des Reaktors.
