Measurement of the $$^{235}$$U(n, f) cross section relative to the $$^{6}$$Li(n, t) and $$^{10}$$B(n, $$alpha$$) standards from thermal to 170 keV neutron energy range at n_TOF

The $$^{235}$$U(n, f) cross section was measured at n_TOF relative to $$^{6}$$Li(n, t) and $$^{10}$$B(n, $$alpha$$), in a wide energy range (25 meV$$sim$$170 keV) with 1.5% systematic uncertainty, making use of a stack of six samples and six silicon detectors placed in the neutron beam. The present results indicate that the cross section in the 9$$sim$$18 keV neutron energy range is indeed overestimated by almost 5% in the recently released evaluated data files ENDF/B-VIII.0 and JEFF3.3. Furthermore, these new high-resolution data confirm the existence of resonance-like structures in the keV neutron energy region. From the present data, a value of 249.7$$pm$$1.4(stat)$$pm$$0.94(syst) b eV has been extracted for the cross section integral between 7.8 and 11 eV, confirming the value of 247.5$$pm$$3 b eV recently established as a standard.

New measurement of the $$^{242}$$Pu(n, $$gamma$$) cross section at n_TOF-EAR1 for MOX fuels; Preliminary results in the RRR

The use of MOX fuels in thermal and fast reactors requires accurate capture and fission cross sections. For the particular case of $$^{242}$$Pu, the previous neutron capture cross section measurements were made in the 70's, providing an uncertainty of about 35% in the keV region. NEA WPEC-26 reports that the capture cross section of $$^{242}$$ Pu should be measured with an accuracy of at least 7-12% in the neutron energy range between 500 eV and 500 keV. This work presents a brief description of the measurement performed at n_TOF-EAR1, the data reduction process and the first ToF capture measurement on this isotope in the last 40 years, providing preliminary individual resonance parameters, as well as a preliminary set of average resonance parameters.
