Original Abstract

The Mini Labyrinth experiment is a neutron and gamma shielding experiment currently being developed at STU. The STU Mini Labyrinth consists of NEUTRONSTOP shielding blocks, water tank, PuBe neutron source, and graphite prism. This paper describes the second construction version of the Mini Labyrinth experiment and presents the newest results of the neutron and gamma fields simulation and measurement. The PuBe neutron source with the emission rate of 1.06E7 n/s was used in the experiment. The measurement of gamma ambient dose equivalent H*(10) and neutron count rates is performed by the Thermo Scientific RadEye portable survey meter and the SNM-11 BF3 corona detector. The simulation part was carried out using state-of-the-art MCNP6 and SCALE6 MONACO stochastic calculation tools, considering the detailed geometry of the Mini Labyrinth and a combined neutron and gamma source of particles. The comparisons were performed between codes and the experiment. The propagation of the cross-section uncertainties was investigated through the shielding analysis. Almost perfect agreements between simulation codes were achieved. The comparison with measurement suggests the further needs of room effect assesment.
