Nuclear Experiment - Abstract
Background:The design of new nuclear reactors and transmutation devices requires to reduce the present neutron cross section uncertainties of minor actinides. Purpose: Reduce the $^{243}$Am(n,$\gamma$) cross section uncertainty. Method: The $^{243}$Am(n,$\gamma$) cross section has been measured at the n_TOF facility at CERN with a BaF$_{2}$ Total Absorption Calorimeter, in the energy range between 0.7 eV and 2.5 keV. Results: The $^{243}$Am(n,$\gamma$) cross section has been successfully measured in the mentioned energy range. The resolved resonance region has been extended from 250 eV up to 400 eV. In the unresolved resonance region our results are compatible with one of the two incompatible capture data sets available below 2.5 keV. The data available in EXFOR and in the literature has been used to perform a simple analysis above 2.5 keV. Conclusions: The results of this measurement contribute to reduce the $^{243}$Am(n,$\gamma$) cross section uncertainty and suggest that this cross section is underestimated up to 25% in the neutron energy range between 50 eV and a few keV in the present evaluated data libraries.

Silica fume cement based materials have long been used in nuclear industry particularly for low-level waste (LLW) and intermediate-level waste (ILW) management. The durability of these materials is therefore of a great importance for the safety of nuclear waste storage. This study investigates the durability in the aspect of tritiated water (HTO) diffusion in relation with the porosity and the microstructure within silica fume cement pastes. Silica fume (SF) was used as a slurry; a liquid mixture of undensified powder and water. Due to its better dispersion, it was found that slurried silica fume improves the pore structure and diffusion properties of SF pastes compared to the use of a densified form of SF. The effect of silica fume and water content were also explored. Silica fume (SF) replacement varying from 0 to 20% by weight of cement was used to prepare cement pastes at water-to-binder ratios (w/b) ranging from 0.3 to 0.5. The manufactured pastes were tested by through-out diffusion and their microstructure characterized by water and mercury porosimetry (MIP), thermogravimetric analysis (TGA) and by scanning electron microscopy (SEM) associated to (EDS) analysis. Test results showed that despite an increase in total porosity, the addition of slurried silica fume has a positive impact on pore refinement and on reducing the effective diffusion coefficients. Finally, HTO diffusion coefficients seem to increase linearly with w/b ratio especially for cement pastes without SF where the increase is more important compared to SF pastes. Keywords: Cement paste Durability Microstructure Slurried silica fume Tritiated water diffusion, 1. Introduction Concrete durability continues to be a subject of considerable interest, especially with the use of cement based materials on structures increasingly demanding on term of sustainability and resistance [...]

Physics ,QC1-999 - Abstract
The accurate calculations of neutron-induced reaction cross sections are relevant for many nuclear applications. The photon strength functions and nuclear level densities are essential inputs for such calculations. These quantities for 235U are studied using the measurement of the gamma de-excitation cascades in radiative capture on 234U with the Total Absorption Calorimeter at n_TOF at CERN. This segmented 4π gamma calorimeter is designed to detect gamma rays emitted from the nucleus with high efficiency. This experiment provides information on gamma multiplicity and gamma spectra that can be compared with numerical simulations. The code DICEBOXC is used to simulate the gamma cascades while GEANT4 is used for the simulation of the interaction of these gammas with the TAC materials. Available models and their parameters are being tested using the present data. Some preliminary results of this ongoing study are presented and discussed.

Physics ,ddc:530 ,Nuclear Experiment - Abstract
Background: The photon strength functions (PSFs) and nuclear level density (NLD) are key ingredients for calculation of the photon interaction with nuclei, in particular the reaction cross sections. These cross sections are important especially in nuclear astrophysics and in the development of advanced nuclear technologies. Purpose: The role of the scissors mode in the M1 PSF of (well-deformed) actinides was investigated by several experimental techniques. The analyses of different experiments result in significant differences, especially on the strength of the mode. The shape of the low-energy tail of the giant electric dipole resonance is uncertain as well. In particular, some works proposed a presence of the E1 pygmy resonance just above 7 MeV. Because of these inconsistencies additional information on PSFs in this region is of great interest. Methods: The γ-ray spectra from neutron-capture reactions on the $^{234}$U, $^{236}$U, and $^{238}$U nuclei have been measured with the total absorption calorimeter of the n_TOF facility at CERN. The background-corrected sum-energy and multi-step-cascade spectra were extracted for several isolated s-wave resonances up to about 140 eV. Results: The experimental spectra were compared to statistical model predictions coming from a large selection of models of photon strength functions and nuclear level density. No combination of PSF and NLD models from literature is able to globally describe our spectra. After extensive search we were able to find model combinations with modified generalized Lorentzian (MGLO) E1 PSF, which match the experimental spectra as well as the total radiative widths. Conclusions: The constant temperature energy dependence is favored for a NLD. The tail of giant electric dipole resonance is well described by the MGLO model of the E1 PSF with no hint of pygmy resonance. The M1 PSF must contain a very strong, relatively wide, and likely double-resonance scissors mode. The mode is responsible for about a half of the total radiative width of neutron resonances and significantly affects the radiative cross section.

Physics ,QC1-999 - Abstract
The 235U neutron-induced cross section is widely used as reference cross section for measuring other fission cross sections, but in the resonance region it is not considered as an IAEA standard because of the scarce experimental data covering the full region. In this work, we deal with a new analysis of the experimental data obtained with a detection setup based on parallel plate ionization chambers (PPACs) at the CERN n_TOF facility in the range from 1 eV to 10 keV. The relative cross section has been normalised to the IAEA value in the region between 7.8 and 11 eV, which is claimed as well-known. Comparison with the ENDF/B-VII evaluation and the IAEA reference file from 100 eV to 10 keV are provided.

Physics ,QC1-999 - Abstract
The 238U fission cross section is an international standard beyond 2 MeV where the fission plateau starts. However, due to its importance in fission reactors, this cross-section should be very accurately known also in the threshold region below 2 MeV. The 238U fission cross section has been measured relative to the 235U fission cross section at CERN – n_TOF with different detection systems. These datasets have been collected and suitably combined to increase the counting statistics in the threshold region from about 300 keV up to 3 MeV. The results are compared with other experimental data, evaluated libraries, and the IAEA standards.

Physics ,QC1-999 - Abstract
Ions and radionuclide diffusivity in concrete is one of the most important factors that determine service life and safety assessment of cement based structures in nuclear power plants and radioactive-waste repositories. Apart from the influence of cement paste microstructure, the presence of aggregates may have an impact on transport properties of the material. The well-known interfacial transition zone, denoted by ITZ, is created near the aggregates and characterized by a greater porosity. The goal of this study is to investigate the competition between the more diffusing ITZ zone and the less diffusing aggregates. To this end, several series of tritiated water diffusion tests are conducted on mortars characterized by different water-to-cement ratios and sand volume fractions. In parallel, microstructure of these materials is explored by mercury and water porosimetry. It was observed that at low sand content (0% – 50%), diffusion properties of mortars are dominated by aggregates dilution effect. At 60% sand, diffusion increases significantly suggesting that percolation’s pores threshold has been reached. Results indicate also that sand particle size distribution has a great impact on the diffusivity of mortars.

Physics ,QC1-999 - Abstract
This article illustrates a contribution of the CEA Laboratory of Concrete and Clay Behavior (“LECBA”s) for the assessment and modeling of the Long-Term behavior of cementitious and clayey materials in the context of nuclear ILW (Intermediate Level Waste) management. In particular, we aim at presenting two main topics that are studied at the Lab. The first one is linked to safety aspects and concern hydrogen transfer within cementitious as well as clayey materials (host rock for French nuclear waste disposal). The second point concerns the assessment of durability properties of reinforced concrete structures in the disposal (pre-closure and post-closure) conditions. Experimental specific tests and phenomenological modelling are presented.

Physics ,QC1-999 - Abstract
The CERN Neutron Time-Of-Flight (n_TOF) facility is well suited to measure low cross sections as those of neutron-induced fission in subactinides. The cross section ratios of natPb and 209Bi relative to 235U and 238U were measured using PPAC detectors and a fragment coincidence method that allows us to identify the fission events. The present experiment provides first results for neutron-induced fission up to 1 GeV. Good agreement is found with previous experimental data below 200 MeV. The comparison with proton-induced fission indicates that the limiting regime where neutron-induced and proton-induced fission reach equal cross sections is close to 1 GeV.

The n-TOF neutron time-of-flight facility at CERN is used for high quality nuclear data measurements from thermal energy up to hundreds of MeV. In line with the CERN open data policy, the n-TOF Collaboration takes actions to preserve its unique data, facilitate access to them in standardised format, and allow their re-use by a wide community in the fields of nuclear physics, nuclear astrophysics and various nuclear technologies. The present contribution briefly describes the n-TOF outcomes, as well as the status of dissemination and preservation of n-TOF final data in the international EXFOR library. © The Authors, published by EDP Sciences, 2017.

The recent improvements in the outcomes of patients with acute lymphoblastic leukemia reflect the progress in the field of diagnostics and the achievements in therapeutic interventions. In particular, the availability of more advanced technology in the cytogenetic and molecular laboratories has resulted in the stratification of patients into specific risk groups and thus several novel agents as well as targeted therapies have been introduced. Additionally, precision medicine will be applicable in the near future and thus the recent developments will facilitate the provision of safer modalities of therapy that may ultimately yield not only higher responses but also improved survival rates. This review represents a recent update on the role of various cytogenetic assays and molecular techniques in patients with acute lymphoblastic leukemia. It is composed of a number of sections including: history of cytogenetics, disease etiology and pathophysiology, utilization of various cytogenetic assays diagnostically, disease-specific cytogenetic and molecular abnormalities, common disease genetic subtypes, prognosis and risk stratification, refractory and relapsed disease, novel therapies, precision medicine and drug repurposing.

Nuclear and High Energy Physics ,Nuclear Experiment - Abstract
The U238 to U235 fission cross section ratio has been determined at n-TOF up to ≈1 GeV, with two different detection systems, in different geometrical configurations. A total of four datasets has been collected and compared. They are all consistent to each other within the relative systematic uncertainty of 3-4%. The data collected at n-TOF have been suitably combined to yield a unique fission cross section ratio as a function of neutron energy. The result confirms current evaluations up to 200 MeV. Good agreement is also observed with theoretical calculations based on the INCL++/Gemini++ combination up to the highest measured energy. The n-TOF results may help solve a long-standing discrepancy between the two most important experimental datasets available so far above 20 MeV, while extending the neutron energy range for the first time up to ≈1 GeV.

The accurate calculations of neutron-induced reaction cross sections are relevant for many nuclear applications. The photon strength functions and nuclear level densities are essential inputs for such calculations. These quantities for
235 U are studied using the measurement of the gamma de-excitation cascades in radiative capture on234 U with the Total Absorption Calorimeter at n_TOF at CERN. This segmented 4π gamma calorimeter is designed to detect gamma rays emitted from the nucleus with high efficiency. This experiment provides information on gamma multiplicity and gamma spectra that can be compared with numerical simulations. The code DICEBOXC is used to simulate the gamma cascades while GEANT4 is used for the simulation of the interaction of these gammas with the TAC materials. Available models and their parameters are being tested using the present data. Some preliminary results of this ongoing study are presented and discussed. [ABSTRACT FROM AUTHOR]- Published

International audience; Durability of silica fume cement based materials is of great importance for radioactive wastestorage. This study investigates the durability in the aspect of tritiated water (HTO) diffusion inrelation with the porosity and the microstructure within silica fume cement pastes. A silica fume(SF) replacement varying from 0 to 20% by weight of cement was used to prepare cement pastesat water-to-binder ratios (w/b) ranging from 0.3 to 0.5. The manufactured pastes were tested bythrough-out diffusion and their microstructure characterized by water and mercury porosimetry(MIP), thermogravimetric analysis (TGA) and by scanning electron microscopy (SEM)associated to (EDS) analysis.It was observed that the addition of silica fume as a slurry –a liquid mixture of undensifiedpowder and water- offers a better dispersion and improves diffusion properties of SF pastescompared to the use of a densified powder, often studied in literature.Test results also showed that despite an increase in total porosity, the addition of silica fume hasa positive impact on pore refinement and on reducing the effective diffusion coefficients.Finally, HTO diffusion coefficients seem to increase linearly with w/b ratio especially forPortland cement pastes where the increase is more important compared to SF pastes.

International audience; Concrete durability continues to be a subject of considerable interest since the use of cementitious materials in the construction of several structures. In particular, cement based materials are largely used in the nuclear industry for the building of nuclear power plants and the infrastructures dedicated to the storage of the radioactive waste. Concrete durability is mainly explained by the resistance of concrete to the penetration of aggressive agents principally by diffusion. The latter is closely related to the mineral composition and the porosity of the material. Therefore, the knowledge of the relationship between microstructure and transport properties is a point of major importance. This work proposes the study of cement pastes and mortars containing Ordinary Portland Cement and Silica fume. Based on a hydration modeling of cement-silica fume pastes, and using a multi scale homogenization approach implemented in a numerical platform, the mineral composition and the effective diffusion coefficient of cement pastes can be estimated. For mortars, and to evaluate the effective diffusion coefficient, finite element simulations with mixed boundary conditions were performed on 3D structures of mortar at different inclusion volume fractions. On another side, mortars were prepared with sand volume fractions ranging from 0 to 60%, a silica fume replacement of 10% by weight and were tested by tritiated water diffusion. The numerical results are confronted with the experimental data and analyzed.

Nuclear Physics - Experiment ,Nuclear Experiment - Abstract
The neutron-induced fission cross section of Np237 was experimentally determined at the high-resolution and high-intensity facility n_TOF, at CERN, in the energy range 100 keV to 9 MeV, using the U235(n,f) and U238(n,f) cross section standards below and above 2 MeV, respectively. A fast ionization chamber was used in order to detect the fission fragments from the reactions and the targets were characterized as far as their mass and homogeneity are concerned by means of α spectroscopy and Rutherford backscattering spectroscopy respectively. Theoretical calculations within the Hauser-Feshbach formalism have been performed, employing the empire code, and the model parameters were tuned in order to successfully reproduce the experimental fission cross-sectional data and simultaneously all the competing reaction channels.

The U238 to U235 fission cross section ratio has been determined at n_TOF up to ≈1 GeV, with two different detection systems, in different geometrical configurations. A total of four datasets has been collected and compared. They are all consistent to each other within the relative systematic uncertainty of 3–4%. The data collected at n_TOF have been suitably combined to yield a unique fission cross section ratio as a function of neutron energy. The result confirms current evaluations up to 200 MeV. Good agreement is also observed with theoretical calculations based on the INCL++/Gemini++ combination up to the highest measured energy. The n_TOF results may help solve a long-standing discrepancy between the two most important experimental datasets available so far above 20 MeV, while extending the neutron energy range for the first time up to ≈1 GeV.
