Gamma and neutron signatures of spent reactor fuel were monitored by small-size silicon diode and track etch detectors, respectively, in a nuclear power plant (NPP). These signatures, reflecting gross gamma intensity and the 242,244Cm content, contai

Using a simple model for PuBe neutron sources, in which the neutrons were assumed to be randomly emitted from the centre of a spherical source, and induce neutron-producing secondary reactions in the material, calculation shows that the ratio of the

Application of CR-39 detectors in spent reactor fuel assay

Autor: L. Lakosi, N.C. Tam, K. Baricza

Publikováno v: Radiation Measurements. 28:781-784

Fast neutrons from reactor fuel were monitored with CR-39 track detectors, using energy discrimination by shape selection to reduce the number of disturbing events. The detectors were irradiated in a steel container placed on the top of assemblies. E
