  • Towards the high-accuracy determination of the U-238 fission cross section at the threshold region at CERN - n_TOF 

    Diakaki, M.; Audouin, Ludmila; Berthoumieux, Eric; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Pretel Sánchez, Carme (EDP Sciences, 2015)

    The U-238 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 ...
  • High accuracy U-235(n,f) data in the resonance energy region 

    Paradela, C.; Durán, I.; Tassan Got, Laurence; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Pretel Sánchez, Carme (EPJ Web of Conferences, 2015)
    Text en actes de congrés
    Accés obert
    The U-235 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 ...
  • Fission fragment angular distribution measurements of U-235 and U-238 at CERN n_TOF facility 

    Leal-Cidoncha, E.; Durán, I.; Paradela, C.; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere (EDP Sciences, 2015)
    Text en actes de congrés
    Accés obert
    Neutron-induced fission cross sections of U-238 and U-235 are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross ...

    Text en actes de congrés
    Accés obert
    Neutron capture cross sections are the key nuclear physics input to study the slow neutron capture process, which is responsible for forming about half of the elemental abundances above Fe. Stellar neutron capture cross ...
  • Measurement of very low (alpha,n) cross sections of astrophysical interest

    The rapid neutron nucleosynthesis process involves an enormous amount of very exotic neutron-rich nuclei, which represent a theoretical and experimental challenge. Two of the main decay properties that affect the final ...
  • Core Exit temperature response during an SBLOCA event in the ASCO NPP 

    Freixa Terradas, Jordi; Martínez Quiroga, Víctor Manuel; Reventós Puigjaner, Francesc (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Given the difficulties in placing measurements in the core region, core exit temperature (CET) measurements are used as a criterion for the initiation of safety operational procedures during accidental conditions in ...
