2025-06-26 Multiphase nanocomposites for small reactor shielding doi:10.57760/sciencedb.25317 en Preparation of SiC/Gd/Pb/W multiphase nanocomposites for SMR shielding requirements. Using XRD, SEM/EDS, density measurement Experimental evaluation of Am Be neutron, Cs-137/Co-60 gamma source, and MCNP6 simulation. In a 20 mm, 5 wt% Gd sample The sub attenuation rate is 75.2%, and the gamma line attenuation coefficient is 0.162 cm ⁻¹ 25% and 18% increase compared to lead plates; Compressive strength 230 MPa, Temperature resistance of 600 ℃. This material has the potential for SMR radiation protection, providing new ideas for the design of collaborative shielding materials.  Small modular reactor; Multiphase composite; Nuclear radiation shielding; Nano SiC; Gadolinium doping SunWenming PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
