Description

The concepts deal with the assessment of hafnium sieve plates (heterogeneous neutron poison) by neutron transmission measurement (hafnium monitor), with the assessment and mass estimate of possible fission product depositions on the sieve plates by measuring their inherent neutron radiation (accumulation monitor) and with the monitoring of the fission product concentration or rather of the fission product concentration profile in the HA column by neutron multiplication measurement (fission product monitor). Such safety instrumentation is suitable for the first extraction column of a WA. (DG)

Abstract (German)

Bei den Konzepten handelt es sich um den Nachweis von Siebboeden aus Hafnium (heterogenes Neutronengift) durch Neutronentransmissionsmessung (Hf-Monitor), den Nachweis und Massenabschaetzung eventueller Spaltstoffablagerungen auf Siebboeden durch Messung ihrer inhaerenten Neutronenstrahlung (Akkumulationsmonitor) und die Ueberwachung der Spaltstoffkonzentration bzw. -konzentrationsprofils in der HA-Kolonne durch Neutronenmultiplikationsmessung (Spaltstoffmonitor). Diese Sicherheitsinstrumentierung eignet sich fuer die erste Extraktionskolonne einer WA. (DG)
