Description

This report describes the work done on the development of an instrumental neutron-activation method for the analysis of impurities in reactor-grade zirconium. Nine samples were analysed, and the results were compared with those obtained by other techniques. No statistically significant differences were observed for ten of the twelve elements that could possibly be determined by instrumental neutron-activation analysis. Cadmium cannot be determined at the 0,5 p.p.m. level, and there is doubt about the comparative values recorded for aluminium. The precision of the measurement by direct instrumental neutron-activation analysis ranges from 1,4 per cent for tungsten to 17 per cent for chromium

Abstract (Afrikaans)

Hierdie verslag beskryf die werk wat in verband met die ontwikkeling van 'n instrumentele neutronaktiveringsmetode vir die ontleding van onsuiwerhede in reaktorgraadsirkonium gedoen is. Daar is nege monsters ontleed en die resultate is vergelyk met die wat met ander tegnieke verkry is. Daar is geen statisties beduidende verskille waargeneem vir tien van die twaalf elemente wat deur instrumentele neutronaktiveringsanalise waargeneem kan word nie. Kadmium kan nie op die peil van 0,5 d.p.m. bepaal word nie, en daar bestaan twyfel oor die vergelykende waardes wat vir aluminium geregistreer is. Die meetpresisie met direkte instrumentele neutronaktiveringsanalise wissel van 1,4 persent vir wolfram tot 17 persent vir chroom
