PROBLEM TO BE SOLVED: To provide slurry for additive manufacturing and a method of additive-manufacturing, particularly a nuclear reactor component.SOLUTION: A method of additive manufacturing includes: developing an additive manufacturing protocol repeatedly using surrogate slurry; replacing therefrom into a final slurry composition; and additive-manufacturing a final component using a developed additive manufacturing protocol. For a nuclear reactor component, the final slurry composition is of nuclear fuel slurry comprising 30 to 45 vol.% of monomer resin, 30 to 70 vol.% of a particle of uranium-containing substance, >0 to 7 vol.% of dispersant, photo-activating dyestuff, light-absorptive material, photo initiator and 0 to 18 vol.% (as a remainder) of diluent. The surrogate slurry has a similar composition, but surrogate particles selected to represent the uranium-containing material are substituted for the particles of the uranium-containing material. The method provides means for in-situ monitoring of characteristics of the final component during manufacture as well as in-situ volumetric inspection. Compositions of surrogate slurries and nuclear fuel slurries are also disclosed.SELECTED DRAWING: Figure 1
