Abstract: The rapid development of nuclear power facility requires the shielding material to be light-weight, and strong in structure,which draws resea-chers' attention to Al based material for its characteristic.This paper focuses on the thermal neutron shielding performance of Al/Gd composites, the thermal neutron transmittance of the composites with different functional particles were computed with Monte Carlo method. By comparing the result ,we conclude that Gd particle does a better job than B4C in improving the shielding performance.Also, we find the content of Gd in the Gd/Al material should not go beyond 6% when the neutron shielding material has a thickness of 2 mm. Finally, we successfully apply this research to optimizing the design for spent fuel storage rack material and conclude that the best thickness and Gd content is 3 mm and 4% respectively.
