An Sn-albedo Monte Carlo-albedo Monte Carlo (Sn-AMC-AMC) coupling technique has been developed and implemented in the AMC code system MORSE-ALB in order to make an effective and accurate shielding calculation for large and complex geometry. This paper describes the feature of the present coupling method which includes new source geometry in the Sn-AMC coupling calculation. Applicability of the present method was studied by analyzing the experiments of neutron streaming in "JOYO". The Sn-AMC-AMC coupling calculation reproduced the measured data within the accuracy of one order of magnitude. Considering that neutron fluxes attenuate by 812 orders of magnitude from the core to the measuring positions and the streaming paths are complicated, the agreement can be regarded good.
