Development of Advanced Manufacturing Technologies for the Production of Large Components to Enhance the Competitiveness of the Spanish Industrial Sector in Nuclear Fusion Energy

The development of nuclear fusion as a viable energy source will require the manufacturing of large-scale and complex components capable of withstanding extreme operational conditions. The RODAS project will address this challenge by developing and validating advanced manufacturing technologies, particularly additive manufacturing and Hot Isostatic Pressing, to fabricate demonstrator components representative of those needed in ITER and EU-DEMO reactors. The project will focus on the production and qualification of fusion-relevant materials such as EUROFER97, CuCrZr, and AISI 316L (ITER-grade), using various additive manufacturing techniques adapted to large-scale applications. Through a coordinated effort among Spanish public research institutions and private technology centers and companies, RODAS will establish specifications, develop hybrid manufacturing routes, and implement non-destructive testing methods to ensure the integrity and performance of the produced components. Additionally, it will explore strategies for future in-service repair using remotely operated systems. The project will significantly strengthen the technological capabilities and international competitiveness of the Spanish industrial sector in the field of nuclear fusion.
