Abstract

Prompt gamma neutron activation analysis is proposed as an instant, non-destructive method for the assay of uranium and also for the determination of 235U-enrichment. Measurements were performed in the thermal and the cold neutron beams at the Budapest Research Reactor. A beam chopper was used to collect the delayed decay gamma radiation from short-lived nuclides separately. Partial gamma ray production cross-sections have been determined for a set of capture prompt, fission prompt and decay gamma lines and compared to those from the literature. The proposed method is also compared to NAA and the passive gamma spectroscopy of natural uranium.
