| 内容記述 | In order to validate copper nuclear data, an integral experiment on copper with the DT neutron source at JAEA/FNS had been performed over 20 years ago. The experiment had showed that ratios of the calculated values to the experimental ones (C/Es) related to lower energy neutrons had been drastically smaller than unity. In order to reveal reasons of the small C/Es, we newly performed the integral experiment on copper with the DT neutron source at JAEA/FNS. A quasi-cylindrical copper assembly of 315 mm in radius and 608 mm in depth was covered with Li2O blocks of 51 mm in thickness for the front and side parts and 153 mm in thickness for the rear part to exclude background neutrons which might affect the measured data. We measured reaction rates with 5 activation foils and fission rates with 2 micro fission chambers at the center of the assembly. The experiment was analyzed by using MCNP5-1.40 with the recent nuclear data libraries, ENDF/B-VII.1, JEFF-3.2 and JENDL-4.0. As a result, the C/E of the reaction rate of the 197Au(n, γ)198Au reaction improved by 10% from the previous result and the combination of the 63Cu data in JEFF-3.2 and 65Cu data in JENDL-4.0 increased the C/E by more 10% because of the resonance data of the 63Cu in JEFF-3.2. Moreover, the calculated result with the 63Cu data in JEFF-3.2 and 65Cu data in JENDL-4.0 with 10% larger elastic scattering cross section data and 10% smaller capture cross section data between 100 eV and 0.3 MeV agreed with the measured one related to lower energy neutrons very well. The copper data should be reassessed. | |||||
