“…An additional ICP-MS result of 0.2035(13) was obtained from the Paul Scherer Institute. Because of the difficulties in describing uncertainties discussed by Noguere et al [19], we decided to use the unweighted mean value of the three ratios: The uncertainty of the average given in equation (3) were taken to be the standard deviation. These calculations yield a value of 0.2045(38) for the 127 I/ 129 I isotopic ratio.…”

Abstract. The thermal neutron capture cross section of 129 I Long Lived Fission Product is determined from chopped cold neutron beam experiments preformed at the PGAA facilities of the Institute of Isotopes. The new experimental value is more precise than the earlier values and is in agreement with recent results of Nakamura et al. and fits well to the differential cross section measurements of Noguere et al. A detailed description of the analysis is given.

Neutron resonance analysis for nuclear safeguards and security applications

Abstract. Neutron-induced reactions can be used to study the properties of nuclear materials of interest in the fields of nuclear safeguards and security. The elemental and isotopic composition of these materials can be determined by using the presence of resonance structures. This idea is the basis of two non-destructive analysis techniques which have been developed at the GELINA neutron time-of-flight facility at JRC-Geel: Neutron Resonance Capture Analysis (NRCA) and Neutron Resonance Transmission Analysis (NRTA). A combination of NRTA and NRCA has been proposed for the characterisation of particle-like debris of melted fuel formed in severe nuclear accidents. In this work, we present a quantitative validation of the NRTA technique which was used to determine the areal densities of Pu enriched reference samples used for safeguards applications. Less than 2% bias has been obtained for the fissile isotopes, with well-known total cross sections.

Neutrons can be used as probes to investigate and study properties of materials and objects. The deep penetration of neutrons into matter allows the study of bulk properties. One evolving activity in this field concerns the existence of resonances in neutron‐induced reaction cross sections in the neutron energy range from thermal up to a few megaelectronvolts for certain nuclides. Since these resonances appear at neutron energies, which are specific for each nuclide, they are very suitable for the determination of the elemental composition of objects and materials. Neutron resonance capture analysis (NRCA) and neutron resonance transmission analysis (NRTA) are two methods used for exploiting the resonance structure in the neutron‐induced reaction cross sections. Both methods are nondestructive, determine the bulk elemental composition, do not require any sample preparation, and result in a negligible residual activity. NRCA is applicable to almost all stable elements, while NRTA is preferred for light elements or nuclei near a closed shell. Quantitative NRCA and NRTA have been used for the analysis of archeological objects and reference materials used for cross‐section measurements. Other applications of neutron resonance spectroscopy range from radiography of nuclear fuel (including spent fuel), detection of explosives and drugs, to thermometry and diamond mining.
