Kolga LLC provides manufacturing support for nuclear power applications, advanced reactor systems, and Nuclear Microreactors. The company produces radiation shielding components, precision-machined parts, and fabricated assemblies used in environments where performance and dimensional control are critical.
Kolga works with lead, tungsten, stainless steel, and other high-density materials to produce shielding systems and mechanical assemblies for nuclear equipment manufacturers, laboratories, and engineering teams. Production covers early prototypes through repeatable manufacturing runs, including casting, CNC machining, fabrication, and assembly of nuclear shielding components.
Primary applications include nuclear shielding systems for instrumentation, detector housings, reactor support hardware, and custom shielding structures used across nuclear energy programs.
Nuclear Market Introduction
Nuclear power systems require components that manage radiation exposure while maintaining structural and mechanical stability under demanding conditions. Shielding performance and precise fabrication are central requirements for equipment used in reactors, monitoring systems, and related infrastructure.
Kolga supports companies working on nuclear power projects and Nuclear Microreactors with components built for radiation attenuation and mechanical integration. Microreactors, in particular, rely on compact layouts and modular construction, which increase the need for tightly controlled shielding geometry and repeatable manufacturing processes.
Kolga provides production support for these systems through machining, casting, and fabrication of nuclear shielding components that fit within complex assemblies and restricted layouts.
Application Categories
- Radiation Monitoring and Detector Shielding: Kolga manufactures HPGe and NaI detector shields, low-background counting chambers, gamma spectroscopy enclosures, and environmental radiation monitoring housings used in nuclear power and laboratory measurement systems.
- Instrumentation and Sensor Shielding: We produce detector collimators, shielding inserts, sensor housings, and machined tungsten or lead components that support controlled sensor placement and stable measurement conditions in nuclear systems.
- Custom Gamma Shielding Components: Kolga supplies machined lead blocks, tungsten collimators, contoured shielding parts, and modular inserts designed for compact layouts and integrated radiation attenuation.
- Fabricated Shielding Assemblies: We build lead-encapsulated steel structures, stainless steel enclosures, welded subassemblies, and modular shielding systems that integrate directly into nuclear and microreactor equipment.
- Radiochemistry, Fuel-Cycle, and Waste Handling Systems: Kolga manufactures shielded assay systems, radiochemistry workstations, sample transfer enclosures, and waste characterization equipment used in nuclear measurement and handling workflows.
- Prototype and Microreactor Development Support: We support Nuclear Microreactor programs with prototype components, shielding mockups, test fixtures, and low-volume production parts for development and validation stages.
Micro Nuclear Power Plants and Reactors
Micro nuclear power plants and Nuclear Microreactors are compact, modular systems designed for decentralized energy production and deployment in constrained environments. They require tightly nuclear shielding, structural, and instrumentation components that maintain precision under demanding thermal and radiation conditions.
Kolga supports these programs by manufacturing shielding and structural parts for reactor modules, containment systems, and instrumentation housings. This includes custom shielding blocks, modular enclosures, and precision-machined interfaces designed for compact reactor layouts.
Work spans prototype development through low-volume production, supporting design validation, iteration, and scale-up. Materials such as lead, tungsten, and stainless steel are used to achieve effective radiation attenuation while maintaining structural integrity and manufacturability.
Prototype-to-Production Support
Kolga supports development from early prototypes through repeatable production for nuclear power and Nuclear Microreactor programs. Engineering input is provided during early design stages to support manufacturability, material selection, and production planning.
Work includes prototype fabrication, design adjustments for production readiness, and low-to-medium volume manufacturing of shielding components and assemblies.
Quality and Documentation
Kolga operates under an ISO 9001:2015-certified quality system covering inspection, material traceability, and production documentation. Inspection tools include handheld CMM systems, digital gauges, and calibrated measurement instruments used across manufacturing operations.
