Key Takeaways
- CRADA resurgence: DOE labs signed a record number of Cooperative Research and Development Agreements in 2024, driven by renewed interest in nuclear power.
- 3D Systems + SRNL partnership: The collaboration focuses on additive manufacturing (AM) of nuclear‑grade valves, pumps, heat exchangers, and future small modular reactor (SMR) components.
- Advanced Manufacturing Collaborative (AMC): A 60,000 sq ft, $50 M facility at the University of South Carolina‑Aiken provides the physical platform for prototyping, testing, and workforce training.
- Commercial impact: The CRADA aims to shorten part‑lead times by up to 70 % and cut material waste by 40 % versus conventional machining, accelerating the path to market for nuclear‑grade AM parts.
What Is a CRADA and Why It Matters
Cooperative Research and Development Agreements (CRADAs) are legally binding contracts that enable U.S. federal labs to partner with private‑sector firms. Under a CRADA, participants can exchange intellectual property, staff, equipment, and laboratory space, and any patents arising from joint work belong to the collaborators. The primary goal is to move promising technologies from the lab to commercial products faster.
Historically, the Department of Energy’s (DOE) national laboratories saw a steep decline in CRADA activity during the early 2000s. By 2024, however, the trend reversed dramatically. Sandia National Laboratories recorded its second‑largest annual CRADA count ever, a milestone attributed to streamlined contracting procedures and a renewed focus on nuclear energy as a clean‑energy cornerstone.
3D Systems and Savannah River National Laboratory (SRNL) Join Forces
Partnership Overview
- Participants: 3D Systems (headquartered in Rock Hill, SC) and Savannah River National Laboratory (SRNL).
- Focus: Deploying additive manufacturing for nuclear‑reactor components, ranging from traditional hardware (valves, pumps, heat exchangers) to emerging SMR parts.
- Location: Work will be conducted inside SRNL’s Advanced Manufacturing Collaborative (AMC), a 60,000 sq ft, $50 M research hub on the University of South Carolina‑Aiken campus.
Strategic Advantages
- Geographic proximity – Both entities operate in South Carolina, simplifying logistics and fostering a regional talent pipeline.
- Workforce development – The AMC doubles as a training ground for engineers and technicians, aligning with DOE’s “Skilled Workforce for Nuclear Manufacturing” initiative.
- Commercial orientation – 3D Systems emphasizes rapid prototyping and scale‑up pathways, aiming to translate lab results into market‑ready products within 18‑24 months.
Additive Manufacturing vs. Conventional Machining for Nuclear Parts
| Metric | Conventional Machining | Additive Manufacturing (AM) |
|---|---|---|
| Lead time (prototype → test) | 12–18 months | 3–5 months |
| Material utilization | 55‑65 % (≈35‑45 % waste) | 85‑92 % (≈8‑15 % waste) |
| Weight reduction | Baseline (0 % change) | 20‑35 % lighter parts |
| Complexity ceiling | Limited to 2‑axis/3‑axis geometries | True 3‑D lattice structures, internal channels |
| Certification timeline | 24‑36 months (due to extensive testing) | 12‑18 months (accelerated by digital twins) |
| Typical cost per part (low‑volume run) | $8,000‑$12,000 | $3,500‑$6,000 |

The table illustrates why DOE and industry leaders view AM as a catalyst for nuclear component modernization. Weight savings translate to lower coolant flow requirements, while higher material efficiency cuts raw‑material expenses—a critical factor for cost‑sensitive SMR projects.
Expected Outcomes and Timeline
| Milestone | Target Date | Deliverable |
|---|---|---|
| Phase 1 – Feasibility & Design | Q4 2024 | Digital twin models for 5 core components (valve, pump, heat exchanger, SMR pressure vessel bracket, coolant channel) |
| Phase 2 – Prototype Production | Q2 2025 | AM‑fabricated test coupons meeting ASTM E23 fatigue standards |
| Phase 3 – Qualification Testing | Q4 2025 | Full‑scale part certification under ASME Section III, Subsection NB |
| Phase 4 – Commercial Launch | Q2 2026 | Market‑ready AM component line for SMR integrators (e.g., NuScale, TerraPower) |
The partnership’s explicit focus on “real‑world commercialization” means each phase incorporates cost‑benefit analyses and supply‑chain risk assessments, ensuring that the technology is not just demonstrable but also economically viable.
Bottom Line
The 3D Systems–SRNL CRADA signals a pivotal shift in how the United States approaches nuclear‑grade manufacturing. By leveraging the AMC’s state‑of‑the‑art additive‑manufacturing capabilities, the collaboration aims to slash part lead times, reduce material waste, and unlock design freedoms unattainable with conventional machining. Coupled with a broader DOE push to revive CRADAs, this partnership could accelerate the deployment of next‑generation reactors—particularly SMRs—while strengthening the regional skilled‑labor pool. For manufacturers and investors watching the nuclear renaissance, the alliance offers a concrete roadmap from prototype to profit in under three years.
