Abstract

The CIELO collaboration has studied neutron cross sections on nuclides that significantly impact criticality in nuclear technologies – 16O, 56Fe, 235,8U and 239Pu – with the aim of improving the accuracy of the data and resolving previous discrepancies in our understanding. This multi-laboratory pilot project, coordinated via the OECD/NEA Working Party on Evaluation Cooperation (WPEC) Subgroup 40 with support also from the IAEA, has motivated experimental and theoretical work and led to suites of new evaluated libraries that accurately reflect measured data and also perform well in integral simulations of criticality.

8. ASSESSMENT OF THE NEUTRON NOISE INDUCED BY STATIONARY FUEL ASSEMBLY VIBRATIONS IN A LIGHT WATER REACTOR

Abstract

A systematic increase of the neutron noise levels over time has been observed in some of the pre-KONVOI PWRs operating in Europe. A possible reason for this anomaly was identified as increased mechanical vibrations of reactor internals, specifically of fuel assemblies. To verify this conjecture, the modeling of stationary vibrations of fuel assemblies and of the corresponding neutron noise is essential. In this paper, using the =d model basis, we illustrate the modeling of the neutron noise sources for fuel assembly vibrations and study the effect of homogenization of cross sections on such stationary perturbations. A comparative analysis between the classical nodal approach (both localized at the boundaries of the vibrating fuel assembly or involving the entire neighboring fuel assemblies) and a pin-wise approach shows that the ‘boundary-localized’ nodal approach seems to capture local noise information, as a pin-wise approach would do, without the need of a complex pin-by-pin model when the detectors are placed close to the perturbation. However, when considering region of the active core away from the perturbation, all three approaches lead to comparable results.

Abstract

The joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutron-induced interactions with the major actinides 235U, 238U and 239Pu, on 241Am and 23Na, 59Ni, Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy.

Abstract

International audience; As part of a bilateral agreement on the study of large axially-heterogeneous oxide-fueled SFR cores, CEA and IPPE have recently performed neutron physics experiments in the BFS facility. The configurations of interest are pancake-shape cores with a split fissile column and a sodium plenum, designed to favor a high inner plutonium conversion ratio and a low sodium void worth. Separate effect tests, including local and global sodium void situations as well as various rodded cases, have been done. The measurements included reactivity effects, spectral indices, detailed reaction rate traverses, neutron importance, etc. The analysis of the experiments with Monte Carlo codes and recent nuclear data files shows the following trends core reactivity is predicted within 1.5 % , depending on the nuclear data file used; sodium voiding in the 91 central tubes is predicted within 0.25 %; the calculated axial reaction rate traverses match the experimental ones; the weight of the simulated control rod is predicted within 10percent.

Abstract

ISBN :978-151082573-4; International audience; In complex innovative fast reactor concepts, fairly detailed core modeling is essential for reliable safety analysis during severe accident scenarios. The CFV core with its axially heterogeneous design, has a negative sodium void reactivity effect, a favorable feature wich increases the inherent system safety in case of sodium boiling. In this work, we studied the impact that the controlrod homogenization model used, and the control rod position, have on the sodium void-reactivity effect and the control rod worth, in the case of a voided CFV core. Three different control rod homogenization models were studied, the traditional 2D equivalence procedure, and two models based on a 3D equivalence procedure, taking into account the axial heterogeneity of the CFV core. It was found that the impact of control rod homogenization has a negligible effect on the sodium void reactivity effect. However, between different control rod positions, a difference of up to 1 dollar in the sodium void reactivity effect was found, hence the control rod position has to be carefully considered when calculating the sodium void reactivity effect. For the control rod worth in a voided CFV core, the traditional 2D procedure, could lead to discrepancies of up to 11% for control rod positions at the top of the core. These discrepancies could be much reduced by control rod homogenization with the 3D equivalence procedure. For the total control rod worth, all models and procedures produced results within the desired error margin of $\pm$ 5%.

Abstract

In this paper, we investigate the possibility of using the CEA Cadarache MASURCA experimental reactor to deliver a well-characterized, fairly-intense beam of intermediate-to-fast energy neutrons. We report the results of numerical simulations which have been performed to establish the feasibility of such a beam. We show that it is possible to achieve a beam in- tensity of more than 108 neutrons cm-2 s-1 in the experimental room past the reactor biological shield, ~80% of the neutrons having energies above 100 keV, and 96% above 10 keV. The characteristics of this MASURCA extracted beam are compared with those of other neutron physics facilities designed to produce continuous beams of fast neutrons. The analysis shows that the MASURCA setup would have several distinctive advantages.

Abstract

Under the sponsorship of the European Community, a group of 6 European research institutions has used state-of-the-art computer programmes and JEF2.2 data to evaluate the mass balances of MOX fuel pins after high-burnup irradiations in three thermal reactors, the PWRs of Saint-Laurent B1, Beznau-1 and BR3. The prediction of these mass balances is satisfactory for Pu isotopes (except Pu238) and Am241, while the other Am isotopes and the curium isotopes were underestimated by 7 to 30%. In general, similar trends are found by CEA with APOLL02 and by Belgonucleaire with WIMS7. The fuel burnup in these irradiations ranged from 10 GWd/t to nearly 100 GWd/t (at the hot spot in BR3). No bias is observed with respect to burnup. In addition, the quality of prediction was about the same in standard lattice PWRs and in overmoderated neutron spectra (BR3). In parallel, a critical review of the basic data files (JEF2.2 versus ENDF/BVI and JENDL3.2) was carried out for 3 isotopes: Am241, Pu240 and Pu242. The impact of the americium and curium underpredictions on some recycling scenario calculations was investigated. While the prediction of waste toxicity is good far a single MOX recycling step, the underestimates and deviations found above for the americium and curium masses imply an underestimation of waste toxicity by about 10% in the case of multiple recycling of actinides. This underestimation would largely increase in the case of dedicated actinide burners.

Abstract

International audience; The main modelling options of ERANOS 2.0, the latest version of the ERANOS fast reactor analysis code and data system, are described. These include the ECCO cell and lattice code (Collision Probability Method in many groups using the subgroup method), the BISTRO 2-D S n transport code, the TGV/VARIANT 3-D Nodal Variational Transport code, and a special procedure for creating equivalent homogeneous cross sections for control rods. The recommended "reference" core calculation route is presented. A summary of the ERANOS extensive validation is provided. It is concluded that ERANOS 2.0 can predict the main characteristics of conventional as well as advanced liquid-metal-cooled fast reactors with an excellent accuracy, and that it can also be used for modelling advanced fast reactor cores, source-driven sub-critical media and gas-cooled fast reactors.

Abstract

VALMOX, an acronym for validation of nuclear data for high burn-up MOX fuels, is one of the projects of the cluster evolutionary fuel concepts: high burn-up and MOX fuels (EVOL). It covers 30 months, from October 2001 to March 2004. It considers the evaluation of the actinide inventory of MOX fuel at high burn-up (typically 60 GWd/t) in light water reactors, with special attention to the helium production. Calculated values for the spent fuel isotopic masses are compared to the measured ones, with sensitivity analyses made in support. The JEF 2.2 nuclear data file is taken as a basis for calculation. The resulting recommendations on nuclear data should be employed in the preparation and testing of the next JEFF3 file. So far, the major effort was placed on the evaluation of MOX fuel irradiations in pressurised water reactors, and first results will be presented and compared. (C) 2004 Elsevier B.V.

30. Investigation of neutron source effects in subcritical media and application to a model of the MUSE-4 experiments

Author

Seltborg, Per, Jacqmin, R., Seltborg, Per, and Jacqmin, R.

Abstract

Monte Carlo simulations have been performed to investigate the neutron sourceeffects in a sub-critical media successively coupled to a (d,d)-source, a (d,t)-source and aspallation source. The investigations have focused on the neutron energy spectra in thefuel and on the source relative efficiency j*. The calculations have been performed forthree sub-critical configurations, representative of the coming MUSE-4 experiments.The Monte Carlo codes MCNP and MCNPX have been used to compute j*. j*has been found to be low for the (d,d)-source (~1.35 compared to 1.0 for an averagefission neutron), while considerably higher for the (d,t)-source (~2.15) and the spallationsource (~2.35). The high value of j* for the spallation source has been shown to be dueto the fraction of high-energy neutrons (17 % of total source with En > 20 MeV) bornfrom spallation, which contribute for 50 % to the total number of fission neutronsproduced in the core. The variations of j* with neutron importance have also beenstudied for some spherical configurations with a (d,d)- and a (d,t)-source. For the class ofvariations considered here, j* was found to remain constant or increase only slightly inthe interval 0.70 < keff < 0.996., QC 20101005

Abstract

The status of the Joint Evaluated Fission and Fusion file (JEFF) is described. The next version of the library, JEFF-3.1, comprises a significant update of actinide evaluations, evaluations emerging from European nuclear data projects, the activation library JEFF-3/A, the decay data and fission yield library, and fusion-related data files from the EFF project. The revisions were motivated by the availability of new measurements, modelling capabilities, or trends from integral experiments. Various pre-release validation efforts are underway, mainly for criticality and shielding of thermal and fast systems. This JEFF-3.1 library is expected to provide improved performances with respect to previous releases for a variety of scientific and industrial applications. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]

Abstract

The CIELO collaboration has studied neutron cross sections on nuclides that significantly impact criticality in nuclear technologies - U-235,U-238, Pu-239, Fe-56, O-16 and H-1 - with the aim of improving the accuracy of the data and resolving previous discrepancies in our understanding. This multi-laboratory pilot project, coordinated via the OECD/NEA Working Party on Evaluation Cooperation (WPEC) Subgroup 40 with support also from the IAEA, has motivated experimental and theoretical work and led to suites of new evaluated libraries that accurately reflect measured data and also perform well in integral simulations of criticality. This report summarizes our results on cross sections and preliminary work on covariances, and outlines plans for the next phase of this collaboration.

Abstract

The joint evaluated fission and fusion nuclear data library 3.3 is described. New evaluations for neutron-induced interactions with the major actinides $^{235}$U, $^{238}$U and $^{239}$Pu, on $^{241}$Am and $^{23}$Na, $^{59}$Ni, Cr, Cu, Zr, Cd, Hf, W, Au, Pb and Bi are presented. It includes new fission yields, prompt fission neutron spectra and average number of neutrons per fission. In addition, new data for radioactive decay, thermal neutron scattering, gamma-ray emission, neutron activation, delayed neutrons and displacement damage are presented. JEFF-3.3 was complemented by files from the TENDL project. The libraries for photon, proton, deuteron, triton, helion and alpha-particle induced reactions are from TENDL-2017. The demands for uncertainty quantification in modeling led to many new covariance data for the evaluations. A comparison between results from model calculations using the JEFF-3.3 library and those from benchmark experiments for criticality, delayed neutron yields, shielding and decay heat, reveals that JEFF-3.3 performes very well for a wide range of nuclear technology applications, in particular nuclear energy.

Abstract

International audience; A systematic increase of the neutron noise levels over time has been observed in some of the pre-KONVOI PWRs operating in Europe. A possible reason for this anomaly was identified as increased mechanical vibrations of reactor internals, specifically of fuel assemblies. To verify this conjecture, the modeling of stationary vibrations of fuel assemblies and of the corresponding neutron noise is essential. In this paper, using the $\epsilon$/$d$ model basis, we illustrate the modeling of the neutron noise sources for fuel assembly vibrations and study the effect of homogenization of cross sections on such stationary perturbations. A comparative analysis between the classical nodal approach (both localized at the boundaries of the vibrating fuel assembly or involving the entire neighboring fuel assemblies) and a pin-wise approach shows that the boundary-localized' nodal approach seems to capture local noise information, as a pin-wise approach would do, without the need of a complex pin-by-pin model when the detectors are placed close to the perturbation. However, when considering region of the active core away from the perturbation, allthree approaches lead to comparable results.

Abstract

International audience; In this paper we investigate the possible future use of the CEA Cadarache MASURCA experimental fast reactor to generate a fairly high-intensity continuous beam of fast neutrons, having energies distributed in the 1 KeV to 5 MeV range. Such an extracted beam of fast neutrons, tailorable in intensity, size and energy, would be rather unique; it would be of interest to neutron-based research and could open a range of new applications at MASURCA. We report the results of numerical simulations which have been performed to evaluate the feasibility of such a beam port and to characterize it spectrally.

Abstract

The time-of-flight (ToF) method with scintillators is routinely used for determining neutron energy. However, a technical difficulty related to the loss of scintillator efficiency below 1 MeV makes this technique difficult to implement for the energy decade [100 keV-1 MeV]. New crystal production techniques provide stilbene scintillators efficient in this low neutron energy region, making it possible to extend the ToF technique below 1 MeV. In this manner, measurements of secondary reactions (d,n) on carbon or oxygen nuclei in this range become feasible, which should lead to improved reference calibration conditions in neutron fields produced by a deuterium ion beam., (© The Author(s) 2023.
