dc.description.abstract | The aim of this work is to provide a precise and accurate measurement of the 238U(n,γ ) reaction cross
section in the energy region from 1 eV to 700 keV. This reaction is of fundamental importance for the design
calculations of nuclear reactors, governing the behavior of the reactor core. In particular, fast reactors, which are
experiencing a growing interest for their ability to burn radioactive waste, operate in the high energy region of
the neutron spectrum. In this energy region most recent evaluations disagree due to inconsistencies in the existing
measurements of up to 15%. In addition, the assessment of nuclear data uncertainty performed for innovative
reactor systems shows that the uncertainty in the radiative capture cross section of 238U should be further reduced
to 1–3% in the energy region from 20 eV to 25 keV. To this purpose, addressed by the Nuclear Energy Agency as
a priority nuclear data need, complementary experiments, one at the GELINA and two at the n_TOF facility, were
proposed and carried out within the 7th Framework Project ANDES of the European Commission. The results
of one of these 238U(n,γ ) measurements performed at the n_TOF CERN facility are presented in this work. The
γ -ray cascade following the radiative neutron capture has been detected exploiting a setup of two C6D6 liquid
scintillators. Resonance parameters obtained from this work are on average in excellent agreement with the ones
reported in evaluated libraries. In the unresolved resonance region, this work yields a cross section in agreement
with evaluated libraries up to 80 keV, while for higher energies our results are significantly higher. | es |
