“…These cross sections were obtained in a pure Maxwellian neutron flux. They complement previous measurements done on 241 Am [14] and 243 Am [6] capture cross sections. The obtained effective and 25.3 meV cross sections are shown in table 4.…”

“…First, a dedicated spectroscopy bench [6] have been installed and connected to the source exchanger of the Lohengrin mass spectrometer (H9 channel). Equipped with Si-and Ge-detectors, it allows a quasi-on-line characterization of irradiated samples by α and γ spectroscopy as well as repeated sequences of irradiation and measurement.…”

Abstract. In the framework of nuclear waste transmutation studies, the Mini-INCA project has been initiated at CEA/DSM to determine optimal conditions for transmutation and incineration of Minor Actinides (MA) in high intensity neutron fluxes in the thermal region. Our experimental tool is based on alpha-and gamma-spectroscopy of irradiated samples and microscopic fission-chambers. It can provide both microscopic information on nuclear reactions (total and partial cross sections for neutron capture and/or fission reactions) and macroscopic information on transmutation and incineration potentials. The 232 Th, 237 Np, 241 Am, and 244 Cm transmutation chains have been explored in details, showing some discrepancies in comparison with evaluated data libraries but in overall good agreement with recent experimental data.

“…The objective of this project is to extend the field of investigation of minor actinides (1), which play an important role in the nuclear waste inventories for future nuclear energy scenarios, and (2) for which nuclear parameters are determined with significant discrepancies between different nuclear data libraries. Several radionuclides have been previously examined [6,7].…”

46The French Atomic Energy Commission has carried out several experiments including the 47 mini-INCA (INcineration of Actinides) project for the study of minor-actinide transmutation 48 processes in high intensity thermal neutron fluxes, in view of proposing solutions to reduce 49 the radiotoxicity of long-lived nuclear wastes. In this context, a Cm sample enriched in 248 Cm 50 (~97 %) was irradiated in thermal neutron flux at the High Flux Reactor (HFR) of the Laue-51Langevin Institute (ILL). This work describes a quadrupole ICP-MS (ICP-QMS) analytical 52 procedure for precise and accurate isotopic composition determination of Cm before sample 53 irradiation and of Cm and Cf after sample irradiation. The factors that affect the accuracy and 54 reproducibility of isotopic ratio measurements by ICP-QMS, such as peak centre correction, 55 detector dead time, mass bias, abundance sensitivity and hydrides formation, instrumental 56 background, and memory blank were carefully evaluated and corrected. Uncertainties of the 57 isotopic ratios, taking into account internal precision of isotope ratio measurements, peak 58 tailing, and hydrides formations ranged from 0.3% to 1.3%. This uncertainties range is quite 59 acceptable for the nuclear data to be used in transmutation studies.

“…It is possible to choose different fissile elements as target in order to maximize the yield of the nucleus of interest. Using the LOHENGRIN recoil mass spectrometer [Loh04], measurement of individual β−spectra from short lived fission products are possible ; in the same irradiation channel, measurements of integral ß-spectrum with the Mini-INCA detectors [Mar06], could be envisaged to perform study on the evolution with time of the antineutrino energy spectrum of a nuclear power plant.…”

“…In complement to individual studies on LOHENGRIN, more integral studies can be envisaged using the so called "Mini-INCA chamber" at ILL [Mar06] in return for adding a β-spectrometer (to be developped). The existing α-and γ-spectroscopy station is connected to the LOHENGRIN channel and offers the possibility to perform irradiations in a quasi thermal neutron flux up to 20 times the nominal value in a PWR.…”

IAEA) is the United Nations agency in charge of the development of peaceful use of atomic energy. In particular IAEA is the verification authority of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). To do that jobs inspections of civil nuclear installations and related facilities under safeguards agreements are made in more than 140 states.IAEA uses many different tools for these verifications, like neutron monitor, gamma spectroscopy, but also bookeeping of the isotopic composition at the fuel element level before and after their use in the nuclear power station. In particular it verifie that weapon-origin and other fissile materials that Russia and USA have released from their defense programmes are used for civil application.
