Rosatom's I.I. Afrikantov Experimental Design Bureau has created regulatory documents for 3D printing in the nuclear industry, specifically for the RITM-200 reactor's third-circuit pump component, the 'Wheel'.

This component was produced using selective laser melting technology with 12Kh18N10T stainless steel. The project, which began with R&D prototypes in 2018 and concluded with testing in 2025, demonstrates the potential of additive manufacturing to improve production efficiency and material properties. The development aims to support serial production of complex components for the nuclear sector.
