Abstract:
In one embodiment, a neutron shielding material is formed 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%, and the boron-adding stainless steel being well in ductility and thermal conduction property.
