The effect of combination of different materials on neutron absorption in a nuclear research reactor spent fuel pool

M. Logar
Abstract
So far, only individual absorbing materials have been studied for neutron absorption in the pool-type reactor spent fuel storages. In this paper, the effect of combining various materials, which are already known as good neutron absorbers by themselves, on lowering the multiplication factor of spent fuel pool, is described. The results of Monte Carlo computer code MCNP calculations for the spent fuel pool of the TRIGA research reactor in Ljubljana, Slovenia, are specified. Due to property completion of the chosen absorber materials, some of their combinations partially decrease the multiplication factor and thus contribute to the enhancement of the safety conditions of the pool.
Kurzfassung
Bisher wurden lediglich einzelne absorbierende Materialien untersucht in Bezug auf die Absorption von Neutronen in Lagerbecken für abgebrannte Brennelemente. In diesem Beitrag wird erstmals der Einfluss der Kombination verschiedener Materialien beschrieben, die ihrerseits bereits als gute Neutronenabsorber bekannt sind. Die Ergebnisse von Monte Carlo Berechnungen mit Hilfe des Rechencodes MCNP für die Neutronenabsorption im Lagerbecken des Forschungsreaktors in Ljubljana, Slovenia, werden vorgestellt. Aufgrund der Eigenschaften der gewählten Absorbermaterialien verringern einige der Kombinationen den Multiplikationsfaktor und tragen somit zur Erhöhung der Sicherheitsbedingungen im Reaktor bei.
