Additive Manufacturing in Türkiye's Nuclear Sector: Business Opportunities from Akkuyu to SMRs
Türkiye's nuclear programme has a localisation target at its core. The Akkuyu Nuclear Power Plant, the Sinop and Thrace projects in planning, and a formal 5 GW Small Modular Reactor (SMR) target are all accompanied by explicit government expectations that Turkish industry will supply an increasing share of the components, materials, and engineering services these plants require. That ambition is credible in many areas. Where it faces its most significant technical challenge is in the manufacturing of complex, high-performance nuclear components from exotic alloys: the parts that traditionally require 12 to 24 months of lead time from specialised international forges, generate enormous amounts of expensive material waste, and depend on fabrication capabilities that Türkiye has not historically maintained at nuclear-grade scale. Additive manufacturing is the technology that changes this calculation. Understanding where it applies, what the Turkish industrial ecosystem can already deliver, and where the gaps remain is the most practically useful analysis for firms evaluating the Turkish nuclear supply chain right now.
Why Conventional Manufacturing Falls Short for Nuclear
The nuclear sector places demands on manufacturing that most industrial processes are not designed to meet. Reactor internals, fuel assembly components, cooling channel structures, and radiation shielding elements often require internal geometries that conventional casting and forging requires high-end acceptable precision. The tooling required for complex shapes either does not exist or adds prohibitive cost and time to the production cycle. This is not a minor inconvenience. It is a structural constraint that limits what can be manufactured domestically and what must be sourced from the handful of international suppliers with the specialist capability to produce nuclear-grade components to these specifications.
The material waste problem compounds the cost challenge. In traditional forging, up to 95% of high-value titanium or Inconel can be wasted as scrap. For high-value exotic alloys, this waste is not merely an efficiency problem. It is a significant cost embedded in every nuclear component produced this way, and it falls directly on the operator, the EPC contractor, or ultimately the project budget. For Türkiye, where the ability to produce nuclear-grade components at internationally competitive costs is a prerequisite for meaningful supply chain localisation, this material inefficiency represents a structural barrier.
Additive manufacturing addresses both constraints simultaneously. By building components layer by layer from powder or wire feedstock, it uses only the material required for the finished part, reducing waste to between 5 and 10% of raw material, with unused powder recoverable and reusable. It enables internal geometries, integrated cooling channels, and complex structural forms that are hard to achieve through conventional methods. Lead times for complex parts drop from 12 to 24 months to 4 to 12 weeks. Components that previously required multiple welded sub-assemblies, each weld a potential failure point over a 60-year plant lifespan, can be produced as single monolithic structures with no joints. The operational and safety implications of that last point are significant: eliminating welds from high-pressure, high-temperature, high-radiation components directly improves the long-term reliability of the plant and reduces the inspection burden across the asset's operational life.
What Türkiye's Industrial Ecosystem Can Already Deliver
Türkiye is not starting from zero in additive manufacturing. The country accounts for 1.3% of global additive manufacturing use as of 2024, with a domestic market valued at USD 390 million. More importantly, the specific industrial capabilities that nuclear additive manufacturing requires are already present in the Turkish ecosystem, though they have not yet been systematically directed toward the nuclear sector.
Turkish Aerospace Industries (TAI) has developed additive manufacturing capabilities that include the ability to print titanium components up to six metres in length. This is not a laboratory capability. It is production-scale capacity for large structural components, and the material and process knowledge TAI has accumulated through aerospace applications translates directly to the demands of nuclear structural fabrication. The qualification standards, the material traceability requirements, and the inspection protocols that aerospace components must meet are closely analogous to those required in nuclear applications. TAI's existing infrastructure is therefore a starting point for nuclear AM qualification.
Ermaksan Additive is Turkey's first domestic producer of metal additive manufacturing machines, with its ENAVISION series representing an indigenous capability in AM equipment manufacturing rather than simply AM component production. This distinction matters for the nuclear localisation argument. A country that can manufacture AM machines domestically is not dependent on imported equipment to run an AM-based nuclear supply chain. It can calibrate, maintain, modify, and expand its production capacity without reference to an international equipment supplier. For the Turkish nuclear programme's long-term localisation trajectory, Ermaksan's position in the ecosystem is more strategically significant than its current market share might suggest.
TUSAŞ Engine Industries (TEI) brings NADCAP-accredited material laboratories and deep experience with high-temperature component design and qualification. NADCAP accreditation is an internationally recognised standard for special processes in aerospace and defence, and it provides a qualification framework that nuclear AM process certification can build on. TEI's experience with components that must maintain structural and chemical integrity under extreme thermal conditions is directly relevant to nuclear reactor internals where temperature, pressure, and radiation impose similarly demanding requirements.
EKTAM, the Additive Manufacturing Technologies Application and Research Centre at Gazi University, functions as the national coordination point for AM research and industrial application. Its mandate covers raw material qualification, process development, and the facilitation of collaboration between defence and energy sectors. For international firms seeking a research and development partner within the Turkish nuclear AM ecosystem, EKTAM provides both the technical infrastructure and the institutional connections to navigate the domestic landscape effectively.
TENMAK, the Turkish Energy, Nuclear and Mining Research Agency, sits above all of these as the central hub for nuclear R&D. Through its NÜKEN institute and facilities at Çekmece and Sarayköy, TENMAK administers grants for localisation and technology development with explicit focus on nuclear safety, hydrogen technologies, and radiation monitoring. For firms seeking to qualify AM-produced nuclear components within a framework that has government backing and regulatory engagement, TENMAK is the institution around which that qualification process will need to be structured.
The Demand Pipeline Across Türkiye's Nuclear Projects
The commercial demand for nuclear additive manufacturing in Türkiye is not a single procurement event. It runs across a multi-decade, multi-project pipeline that creates layered and recurring opportunities for firms that establish capability and certification within the market now.
Akkuyu is the immediate demand source. Four VVER-1200 reactors totalling 4.8 GW are in commissioning and early operation under Rosatom's Build-Own-Operate model. The operational phase of a nuclear plant generates continuous demand for replacement components, inspection tooling, maintenance fixtures, and specialised repair parts. Many of these are low-volume, high-complexity items for which additive manufacturing offers clear advantages over conventional production: faster delivery, lower tooling cost, and the ability to produce legacy components whose original manufacturing specifications may no longer be commercially available. As Akkuyu's operational years accumulate, this demand will grow, not diminish.
Sinop, a planned 4.8 GW project being negotiated under a trilateral framework involving the United States and South Korea with a focus on Generation III+ technology, and Thrace, a proposed 5.6 GW facility in discussions with China's SPIC, both carry explicit localisation expectations that will shape their respective supply chain structures. For firms that have established nuclear AM qualification credentials and supplier relationships within the Turkish ecosystem by the time these projects reach procurement, the competitive position is substantially stronger than for those entering at the tender stage.
The SMR programme is where additive manufacturing's advantages are most structurally aligned with programme requirements. Türkiye's formal 5 GW SMR target, supported by active discussions with technology developers from the United States, Canada, France, and the United Kingdom including Rolls-Royce, envisions deployment for industrial clusters, data centres, and remote regions. SMRs are by design modular, factory-fabricated systems where the economics of production depend on standardised, repeatable manufacturing at competitive cost. Additive manufacturing's ability to produce complex components in shorter lead times and with lower material waste is directly compatible with the production model that makes SMR economics work. For international SMR technology developers who are simultaneously evaluating Türkiye as a deployment market and as a potential manufacturing partner, the Turkish AM ecosystem's existing aerospace and defence capabilities represent a supply chain foundation that reduces the cost and risk of localised SMR component production.
What the Market Requires From New Entrants
For international additive manufacturing firms evaluating the Turkish nuclear market, the pathway to participation runs through qualification rather than through sales. Nuclear AM components must meet material certification, process documentation, and traceability standards that are more demanding than most industrial applications. The qualification process is time-consuming and requires sustained engagement with both the regulatory framework administered through TENMAK and the technical standards applicable to the specific reactor technology in question.
The firms that will build durable positions in this market are those that engage with the Turkish AM ecosystem as partners rather than as vendors. Working with TENMAK on localisation grant programmes, collaborating with EKTAM on process qualification, and building technology relationships with TAI and TEI creates the institutional credibility and regulatory familiarity that nuclear procurement requires. The Turkish nuclear additive manufacturing market is not yet crowded. The firms that arrive with a qualification strategy, a partnership structure, and a clear understanding of which components across Akkuyu's operational needs, Sinop and Thrace's construction requirements, and the SMR programme's production economics they are best positioned to serve will find a market that is structured to reward early, well-prepared engagement over reactive bidding.
That trajectory is also beginning to take clearer commercial shape through industry platforms such as the Türkiye Nuclear Business Platform (TNBP) 2026 (26–27 August, Ankara), where policymakers, investors, and technology vendors are expected to further define investment frameworks and partnership pathways, reinforcing the advantage for firms that engage early and position themselves within the ecosystem ahead of large-scale procurement cycles.
