Abstract

Neutron and gamma spectra were measured behind and inside of modules consisting of variable iron and water slabs which were installed in radial beams of the zero-power training and research reactors AKR of the Technical University Dresden and ZLFR of the University of Applied Sciences Zittau/Görlitz. The applied NE-213 scintillation spectrometer allowed the measurement of gamma and neutron fluence spectra in the energy regions 0.3–10 MeV for photons and 1.0–20 MeV for neutrons. Measurements with thermoluminescence dosemeters (TLD) between slabs supplied additional information about the space distribution of energy integrated fluxes. The paper describes the experiments and presents some important results of the measurements. They will be compared with the results of transport calculations made by means of MCNP and TRAMO in another paper.

Abstract

An den Nullleistungs-Ausbildungsreaktoren AKR der Technischen Universität Dresden und ZLFR der Hochschule Zittau/Görlitz (FH) wurden Neutronen- und Gammaspektren hinter und innerhalb von Transmissionsmodulen gemessen. Diese bestanden aus Eisen-Wasserschichten verschiedener Dicken. Das verwendete NE-213 Szintillationsspektrometer ermöglichte die Messung von Gamma- und Neutronenflussspektren im Energiebereich von 0,3± 10 MeV für Photonen und 1,0–20 MeV für Neutronen. Messungen mittels Themolumineszenzdosimeter (TLD) zwischen den verschiedenen Schichten lieferten ergänzende Informationen über die räumliche Verteilung der energieintegralen Flüsse. Die Arbeit beschreibt die Experimente und einige wichtige Ergebnisse. Der Vergleich mit Rechnungen der Transportcodes MCNP und TRAMO erfolgt in einem anderen Artikel.
