With over 20 years of experience in the nuclear industry, ATS delivers high-reliability software solutions that power some of the world’s most critical systems. Our integrated in-house offering and deep domain expertise in automation and nuclear applications enables us to design, develop, and support software that meets the highest standards of safety, performance, and compliance.
Navigating Complexity in Critical Environments
Nuclear operators face unique challenges that demand precision, reliability, and regulatory compliance:
Legacy System Constraints
Many nuclear facilities use aging control and software systems that require modernization without compromising safety.
Stringent Regulatory Oversight
Nuclear operators must meet rigorous regulatory requirements, with software systems expected to support validation, traceability, and audit readiness.
Zero Tolerance for Downtime
System failures carry serious safety, financial, and operational consequences, requiring software designed for reliability and fault containment.
Cybersecurity Exposure
As control systems become more connected, nuclear facilities face increased cybersecurity risk across operational and safety-critical environments.
Real-Time Performance Demands
Need for deterministic performance in real-time safety-critical applications.
What is High-Reliability Software?
Categorized software systems that are designed, developed, and maintained to operate consistently and correctly over time, especially in critical environments where failures can have severe consequences.
High-reliability software reduces the risk of failure through disciplined engineering, robust design, and continuous monitoring.
