Description

Central reactivity coefficients (CRCs) of the structural materials Cr, Fe, Ni and stainless steel are studied for a number of fast reactor assemblies. The discrepancies between measured and calculated material values are discussed. In order to localize possible sources of error, the relative contribution of absorption, elastic and inelastic scattering, and the sensitivity of the material values to errors in cross section data are brought in relation to the amount of disagreement between theory and measurement. (orig.)

Abstract (German)

Zentrale Reaktivitaetskoeffizienten (CRCs) der Strukturmaterialien Cr, Fe, Ni und Edelstahl werden fuer eine Reihe von Schnellreaktor-Bausaetzen untersucht. Die Diskrepanzen zwischen gemessenen und berechneten Materialwerten werden diskutiert. Zur Lokalisierung moeglicher Fehlerquellen werden der relative Beitrag von Absorption, elastischer und inelastischer Streuung und die Empfindlichkeit der Materialwerte gegenueber Fehlern in den Querschnittsdaten zu der Groesse der Diskrepanz zwischen Theorie und Messung in Beziehung gesetzt.
