Abstract:
1. A neutron shielding material made of boron-adding stainless steel of either austenite-ferrite two-phase stainless steel or ferritic stainless steel, the austenite-ferrite two-phase stainless steel containing, in mass %, B: 0.5% to 2.0%, Ni: 3.0% to 10.0%, and Cr: 21.00% to 32.00%, the ferritic stainless steel containing, in mass %, B: 0.5% to 2.0%, Ni: 4.0% or less, and Cr: 11.00 to 32.00%, the boron-adding stainless steel being well in ductility and thermal conduction property, and wherein a ferrite phase ratio of the austenite-ferrite two-phase stainless steel falls within a range of 7% to 98%.
