Measuring system for the determination of the neutron flux density distribution
Description
The neutron flux density distribution in the core of, e.g. a pressurized-water power reactor, is recorded by an emitter which is activated by neutrons. The evaluation equipment with the collectors surrounding the collector sections in the area of measurement is situated outside the reactor core. The evaluation equipment is connected to the reactor core by a guide tube through which the emitter which is flexibly constructed as a helical spring is pneumatically guided. The collectors are ceramic tubes on which a metal film is deposited by evaporation. They are individually connected to the measuring instruments. (DG/AK)

Die Neutronenflussdichteverteilung im Kern z.B. eines Druckwasserleistungsreaktors wird mit einem durch Neutronen aktivierbaren Emitter aus Vanadium aufgenommen. Die Auswertestelle mit den dazugehoerigen, den Emitter abschnittweise in der Messstellung umgebenden Kollektoren befindet sich ausserhalb des Reaktorkerns. Von diesem zur Messstelle fuehrt ein Fuehrungsrohr, durch das der als Schraubenfeder flexibel ausgebildete Emitter mit Druckluft gefuehrt wird. Die Kollektoren bestehen aus Keramikrohren, auf die eine Metallschicht aufgedampft ist. Sie sind einzeln mit Messgeraeten verbunden. (DG)Files
