Abstract

The present work shows the development of k0- instrumental neutron activation analysis (k0-INAA) method at the Malaysian Nuclear Agency research reactor. To use the k0-INAA method, two formalisms were regulated according to 1/m and non-1/m (n, c) reaction nuclides. The reactor neutron spectrum parameters, the thermal to epithermal neutron flux ratio (f), the epithermal neutron flux shape factor (a) were measured using the bare bi-isotopic monitor and bare triple monitor methods, respectively, based on the Høgdahl convention. In addition, the modified spectral index r(a)√Tn=T0, the Westcott gLu(T n) factor and the absolute neutron temperature Tn parameters were determined using the Westcott formalism. 176Lu was used as non- 1/v monitor while 197Au, 96Zr and 94Zr were used as 1/v monitors. The average values of r(a) √Tn=T0; gLu(Tn) and Tn were determined to be 0.1795 ± 0.0044, 1.9729 ± 0.0234 and 50.12 ± 3.21°C, respectively. The accuracy of the method was evaluated by analysing IAEA-Soil 7, IAEA-SL 1, NBS SRM 1633A-1 and IAEA-Soil 375 as reference materials. The results show an acceptable level of consistency.
