Times Cited Count：4 Percentile：33.73(Physics, Multidisciplinary)Lead is an important candidate material as multiplier of nuclear fusion reactor. Few DT neutron integral benchmark experiments were performed for lead so far. Therefore, we have carried out an integral benchmark experiment on lead at the DT neutron source facility of JAEA, FNS. A cubic lead assembly on a side of 45.3 cm was set up and was irradiated with the DT neutron source. Reaction rates of the

In reactions were measured as fast neutron spectrum indices in the assembly. A small NE213 spectrometer was also used for measurement of neutron spectra in the assembly. A Monte Carlo calculation code, MCNP5, was adopted to calculate the above neutron spectra and activation reaction rates. Nuclear data libraries, JENDL-3.3, ENDF/B-VII.0, JEFF-3.1 and FENDL-2.1, were used in the calculation. The calculation results of the three libraries except for JENDL-3.3 agreed with the measuring ones. In case of JENDL-3.3, some remarkable disagreements were found. From our investigations, it was pointed out that the inappropriate evaluation of the (n,2n) and inelastic cross sections of lead in JENDL-3.3 caused such disagreement.

Lead is considered as one of the candidates of the neutron multiplier in the blanket of a fusion reactor. A benchmark experiment with a DT neutron source aiming at the accuracy validation of nuclear data evaluated for lead was thus carried out in the Fusion Neutronics Source facility of Japan Atomic Energy Agency. A lead cubic assembly of 45 cm in thickness was constructed, and the reaction rate measurement with activation foils (In, Ni, Al, Nb, Zr) of which the threshold energy is above 0.3 MeV and the neutron spectrum measurement with an NE213 detector inside the assembly was conducted. We found that the calculation with JENDL-3.3 showed the very large underestimation of the neutron flux above 10 MeV as increasing of depth, and its magnitude was approximately 50% at 40 cm depth. On the other hand, the calculations with ENDF/B-VII.0 and JEFF-3.1 reproduced the experimental values comparatively well.
