Complex nuclear solutions need more than engineering—they need the right environment to prove that they will perform as intended. ATS Nuclear Energy Solutions provides the infrastructure and facilities to help organizations across the nuclear supply chain increase capacity, improve throughput, strengthen quality, reduce labor constraints, improve safety, and create the production systems needed to support the next generation of nuclear deployment.
Our facilities offer our nuclear customers the space where nuclear tooling, automation, processes, and equipment can be developed, tested, optimized, and validated before deployment. With dedicated nuclear manufacturing capabilities in Ontario and Ohio, along with specialized mock-ups, water-pit testing, and a Centre of Excellence, ATS helps customers reduce uncertainty and improve project readiness.
The Challenges We Address
Testing in Realistic Conditions
Nuclear systems often need to perform in environments that are difficult or impossible to replicate in a conventional manufacturing facility. Purpose-built mock-ups and testing infrastructure allow teams to validate equipment and processes under realistic operating conditions before deployment.
Reducing Deployment Risk
Discovering an issue for the first time in the field can have significant safety, schedule, and cost implications. Early testing and validation help identify design and integration challenges while there is still time to address them.
Schedule & Outage Pressure
Nuclear projects and outages operate within demanding schedules where delays can quickly affect the critical path. Facility-based testing allows development and troubleshooting to happen before equipment reaches site, reducing commissioning and deployment uncertainty.
Complex System Integration
Automated tooling must work with existing equipment, infrastructure, processes, and operators. Full-scale mock-ups and dedicated test environments provide an opportunity to verify interfaces and system integration before field deployment.
Specialized Nuclear Manufacturing
Nuclear equipment requires specialized manufacturing processes, quality controls, and expertise. Dedicated nuclear manufacturing environments provide the infrastructure needed to build and prepare complex systems to demanding nuclear requirements.
Workforce Readiness
Successful deployment depends on teams being familiar with equipment, processes, and operating procedures before work begins. Realistic facilities and mock-ups provide an environment for hands-on testing, training, and process development allowing for our teams to work collaboratively with yours.
Our Solutions
Mock-Ups & Full-Scale Replication
Create realistic representations of nuclear environments, equipment, and processes to test tooling, validate workflows, and identify potential issues before deployment. Mock-ups can be tailored to replicate critical interfaces and operating conditions.
Water Pit Testing
Use dedicated water-pit infrastructure to test underwater tooling, reactor component handling, segmentation, inspection, and other applications in realistic conditions. Testing helps validate equipment performance, operator procedures, and system integration before entering a nuclear environment.
Integrated Testing & Validation
Bring engineering, manufacturing, automation, and testing together to validate complete systems before deployment. Integrated testing helps verify performance, interfaces, controls, and operating procedures in a controlled environment.

Process Development & Optimization
Use dedicated facilities to evaluate and refine processes before implementation in the field. Teams can test different approaches, identify opportunities for automation, and establish repeatable procedures that improve project execution.

Key Benefits
The advantages of partnering with us.
Reduce Deployment Risk
Test and validate equipment, processes, and interfaces before they reach the nuclear environment, helping identify and resolve issues earlier in the project.
Improve Schedule Certainty
Complete testing, integration, and troubleshooting ahead of field deployment to reduce commissioning uncertainty and protect critical path activities.
Prove Performance Before Deployment
Demonstrate that tooling and systems can meet defined performance requirements under realistic operating conditions before they are deployed.
Accelerate Innovation
Give engineering and project teams the physical environment and specialized infrastructure needed to rapidly develop, prototype, test, and refine new nuclear solutions.
Improve Workforce Readiness
Allow operators, engineers, and maintenance teams to become familiar with equipment and processes through realistic testing, training and hands-on experience before deployment.
Build With Confidence
Bring engineering, manufacturing, automation, and testing together in one controlled environment to deliver solutions that are better prepared for the demands of the nuclear environment.
Applications
Real-world use cases across industries.

Nuclear Refurbishment
Replicate reactor environments and critical interfaces to test component replacement tooling, underwater systems, inspection equipment, and automated processes before an outage. This enables teams to troubleshoot and optimize operations before critical path work begins.

Nuclear Decommissioning
Test segmentation, cutting, handling, and waste processing systems in controlled environments before deployment to radiological areas. Mock-ups and water-pit testing can help validate tooling performance, operator procedures, and waste handling workflows.

SMR & New Build
Support first-of-a-kind development by providing the facilities needed to prototype, test, and validate new tooling, automation, manufacturing processes, and reactor-specific systems before they are deployed at scale.

Nuclear Fuel Fabrication
Provide dedicated manufacturing and testing environments for the development and integration of automated fuel fabrication systems, material handling equipment, and specialized tooling.
Prove It Before You Deploy It
From full-scale mock-ups and water-pit testing to dedicated nuclear manufacturing, ATS Nuclear Energy Solutions provides the infrastructure to turn complex nuclear solutions into proven, deployment-ready systems.
