Nuclear operations depend on disciplined maintenance, clear priorities, and consistent execution under strict regulatory oversight. Reliability engineering in this environment carries a different level of responsibility than it does in most other industries because failure, compliance, and asset life all carry greater operational weight.
A strong reliability program helps teams focus on the assets that matter most, understand how and why failures occur, and plan maintenance activities that support stable run cycles. With clearer access to asset data, work packages, and parts readiness, teams are better prepared to execute work safely and efficiently, especially in high-radiation environments where timing and preparation matter.
If your goals include fewer forced outages, stronger compliance, and better control of maintenance scope, reliability engineering provides a practical and structured path forward.
Why Reliability Engineering in Nuclear Requires a Different Standard
Nuclear reliability engineering reaches beyond uptime. It supports decisions where safety, traceability, and long-term asset performance carry direct operational and regulatory weight.
- Risk-informed maintenance planning matters at every stage of operation. Maintenance efforts need to align with asset criticality, operating realities, and plant risk, not with fixed routines alone.
- Configuration control and traceability remain essential. Component history, engineering changes, and maintenance actions must stay documented and easy to validate over long operating periods.
- Aging management affects every lifecycle decision. Nuclear assets often stay in service for decades, which places added focus on degradation monitoring, refurbishment planning, and replacement timing.
- Human reliability also plays a central role. Operator actions, maintenance errors, and procedural compliance affect execution quality as much as equipment condition does.
The Challenges We Address with Reliability Engineering
Recurring failure points can consume outage windows and lead to repeat work. Many teams already understand where issues exist but lack a consistent method to address them at the source. Reliability engineering helps bring structure and focus to these efforts.
Unclear Asset Criticality
When all assets are treated with equal urgency, higher-risk systems may not receive the attention they require. Criticality assessments help align maintenance effort with safety, production impact, and operational risk.
Recurring Forced Outage Drivers
Forced outages are often linked to known failure points or decisions around redundancy that no longer reflect operating realities. Reliability engineering helps teams revisit these areas and align mitigation actions with current priorities.
Asset Data Trapped in Static Documents
When bill of materials (BOMs) and asset records are difficult to search, teams may spend valuable time locating information. Structured maintenance data improves access to accurate records and validated work packages.
High-Radiation Execution Constraints
Work in high-radiation areas requires tight scope definition, strong preparation, and clear procedural discipline before access windows begin. ALARA-focused work packages support safer execution while helping teams improve coordination and productivity during constrained maintenance periods.
Regulatory and QA Alignment Gaps
Nuclear facilities operate within strict regulatory frameworks. Procedures, training, and execution practices must align with requirements from organizations such as the Nuclear Regulatory Commission (NRC) and the Canadian Nuclear Safety Commission (CNSC), as well as internal Quality Assurance (QA) standards.
Our Approach
ATS Nuclear Energy Solutions applies reliability-centered maintenance principles to develop preventive maintenance strategies aligned with asset criticality, failure modes, and operating conditions.
Asset Management
Align Assets with Risk, Lifecycle, and Investment Decisions
ATS Nuclear Energy Solutions works with your team to define an asset management framework that supports long-term performance and safety. This includes assessing current practices, identifying asset criticality, and developing lifecycle strategies that align maintenance, capital planning, and operational priorities.
With a clearer view of asset health and risk, your team can make more informed decisions around refurbishment, replacement, and long-term investment.
Preventive Maintenance
Reduce Failures Through Structured, Risk‑Based Maintenance
Preventive maintenance is most effective when it reflects how equipment behaves in real operating conditions. ATS develops maintenance strategies based on failure modes, asset criticality, and operating context.

Digital Solutions
Operational Insight for Informed Decision-Making
Digital tools can improve visibility into asset condition, system performance, and maintenance effectiveness. Solutions such as Illuminate™ Manufacturing Intelligence, digital twins, and condition monitoring help teams identify emerging issues and track performance over time.
These tools support maintenance strategies without adding unnecessary complexity to daily operations. They also improve access to information at the point of work, which can support both compliance and quality.
Operational Assessments
Understand Risk Before You Invest
Operational assessments give you a clear view of where reliability risks and improvement opportunities exist. ATS offers structured assessments that evaluate asset health, maintenance practices, data quality, and operational execution. Each assessment delivers prioritized recommendations so you can focus effort and investment where it delivers the greatest reliability and risk reduction impact.
