Description

Automatic translation: In the radiation test FRJl-MFl, the neutron-induced changes should of carnelian strength and dynamic modulus of elasticity of the monolith reference matrix A3-Iso 3 up to 1 x 10 2 1 E> 0.1 MeV can be measured and correlated with one another. From the monolith block manufactured by HOBEG for this purpose with 54 pressed-in cooling channels but without fuel zones, 191 samples were systematically taken and the density, the spec. electr. Resistance and the dyn. E-module measured. The aim of this paper is to provide the measurement results beyond the requirements of the radiation test to analyze statements about spread, axial and radial gradients in the monolith block as well as possible Obtain correlations between the properties.

Abstract (German)

Im Bestrahlungstest FRJl-MFl sollen die neutroneninduzierten Änderungen von Carneirofestigkeit und dynamischem E-Modul der Monolith-Referenzmatrix A3-Iso 3 bis zu 1 x 1021 E > 0,1 MeV gemessen und miteinander korreliert werden. Aus dem zu diesem Zweck von HOBEG gefertigten Monolithblock mit 54 eingepreßten Kühlkanälen jedoch ohne Brennstoffzonen wurden systematisch 191 Proben entnommen und an ihnen die Dichte, der spez. elektr. Widerstand und der dyn. E-Modul gemessen. Ziel des vorliegenden Papiers ist es, die Meßergebnisse über die Anforderungen des Bestrahlungstests hinaus zu analysieren, um Aussagen über Streubreite, axiale und radiale Gradienten im Monolithblock sowie mögliche Korrelationen zwischen den Eigenschaften zu erhalten.
