Fusion neutron skyshine experiment at FNS

Nakao, Makoto*; Nishitani, Takeo; Ochiai, Kentaro

FAPIG, (168), p.9 - 13, 2004/11

Fusion neutron skyshine experiment have been carried out at the FNS(Fusion Neutronics Source) facility of Japan Atomic Energy Research and Institute. In this experiment, the skyshine port located just above the tritium target from which fusion neutron produced was open and the radiation dose rate of skyshine neutron that went out through the skyshine port was measured as far as about 550 m away from the tritium target with a spherical rem-counter. The measured neutron dose rate was compared with the calculation value by Monte Carlo simulation code MCNP-4B and a simple line source model.

The neutron penetration and the activation characteristics of the boron-doped low activation concrete were investigated for irradiation of 2.45 and 14 MeV neutrons. The shielding property of the 2 wt% boron-doped low activation concrete is superior to that of the 1 wt% boron for the thermal neutron, on the contrary to the no clear difference for the fast neutron. The total activity detected in the boron-doped low activation concrete was about one hundredth of that in the geostandard sample at more than 30 days cooling time. The total activity of the boron-doped concrete by major nuclei does not depend on the boron density for the 14 MeV neutron irradiation.
