The Rise of Small Modular Reactors
The nuclear industry is entering a new era. Unlike traditional nuclear power plants that rely on gigawatt-scale output, SMR technology represents a new class of compact, scalable systems typically producing up to 300 MW(e) per module. These small modular reactors can be built in factories, shipped, and assembled on-site, enabling faster deployment, smaller footprints, and reduced costs while efficiently generating electrical power for diverse applications.
These innovative technologies enable SMRs to serve as versatile power solutions, supplying external power for remote regions, industrial facilities, and national grids alongside renewable energy sources. Their enhanced safety systems, passive systems for cooling, and modular designs make them a cornerstone of the next generation of nuclear reactors.
Engineering for Reliability and Safety
In the nuclear power industry, reliability is non-negotiable. Even the smallest leak or material degradation can impact operational safety and reactor performance. That’s why Elcon’s components are engineered to perform under the most demanding conditions, from high neutron flux and radiation exposure to extreme heat, vacuum, or pressurized coolants.
Through advanced vacuum brazing and hermetic sealing, Elcon produces ceramic-to-metal assemblies that maintain their integrity throughout years of continuous operation. Each component is built for long-term reliability, preventing leaks, protecting sensitive electronics, and ensuring the sustained performance of SMR systems.
Key applications include:
- Control rod actuator assemblies
- Pressure and temperature sensor feedthroughs
- Power penetration seals for containment vessels
- Radiation-hardened electrical connectors
Materials That Withstand the Impossible
SMRs operate in some of the harshest environments imaginable, where thermal, chemical, and radiation stresses constantly push materials to their limits. Elcon’s deep understanding of material science enables us to manufacture components that meet these challenges head-on.
- Ceramics (Alumina, Zirconia): Provide exceptional insulation, dielectric strength, and radiation resistance for feedthroughs and electrical insulators.
- Metals (Kovar, Inconel, Titanium, Stainless Steel): Deliver unmatched structural stability, corrosion resistance, and thermal endurance in reactor environments.
- Braze alloys (Copper, Silver, CuSil, Gold): Ensure durable, high-temperature sealing between materials with CTE mismatches—critical for hermetic joints and long-lasting performance.
Every material is chosen for its compatibility, enabling our team to build multi-material assemblies that thrive where other equipment fails.
Photochemical Etching for Precision Components in the Nuclear Industry
Precision matters in every facet of SMR design. Designed with precision in mind, Elcon’s advanced photochemical etching technology enables the production of complex, high-tolerance metal parts without introducing mechanical stress, making it ideal for components requiring micro-scale accuracy and repeatability.
Our proven process makes us leaders in specialty products, including:
- Fuel cladding spacers and springs for fuel assemblies
- Cooling channel plates for heat exchanger stacks/heat sinks
- Neutron shielding grids and foils
- Instrumentation filters/mesh/screens and sensor housings
These etched parts help optimize fluid flow, enhance heat exchange efficiency, and reduce the risk of contamination or mechanical fatigue, all key elements for maintaining operational safety and long-term reliable energy production.
