When critical nuclear tooling goes down, every minute counts. Missing, obsolete, non-compliant, or difficult-to-source components can delay outage schedules, impact refurbishment and maintenance activities, and increase operational risk.
ATS Nuclear Energy Solutions helps nuclear facilities stay ahead of these challenges with comprehensive spare parts, inventory management, and procurement solutions designed to keep critical tooling operational and projects on schedule.
Why Nuclear Facilities Need Proactive Spare Parts Management
Nuclear facilities face unique spare parts challenges that can affect tooling availability, maintenance efficiency, and operational performance.
Stockout Risk
Missing critical replacement spare parts and subassemblies can halt tooling operations, delay outage schedules, and put project timelines at risk.
Component Obsolescence
As equipment ages, discontinued and end-of-life components become increasingly difficult to source, increasing downtime risk and lifecycle costs.
Strict Nuclear Quality Requirements
Nuclear spare parts often require extensive documentation, traceability, calibration records, and certificates of compliance, creating additional complexity for maintenance and procurement teams.
Procurement Complexity
Managing multiple suppliers, verifying part compatibility, and maintaining inventory across systems and facilities can place significant demands on internal resources.
Lead Time Delays
Extended procurement cycles can slow equipment recovery and create unnecessary cost and risk during outages, refurbishment projects, and other highly time-sensitive nuclear operations.
Rising Maintenance Costs
Reactive maintenance approaches often result in emergency repairs, expedited parts sourcing, and unplanned downtime, driving up maintenance costs and straining internal resources.
Our Approach to Spare Parts and Subassemblies
Comprehensive spare parts, subassembly, and lifecycle support to help nuclear facilities improve parts availability, reduce operational risk, and keep critical tooling performing at its best.
Critical Spare Parts Planning
Prioritizing Crucial Components Before They’re Needed
Establish a proactive inventory strategy with Recommended Spare Parts Lists (RSPLs) tailored to specific tooling systems and operational requirements. Our experts identify the components most likely to impact tooling performance and prioritize them for stocking based on availability, lead times, and criticality. This helps balance inventory costs while protecting schedules and operational performance.
Strategic Spare Part & Subassembly Programs
Ensuring Essential Components Are Compliant and Within Reach
Receive fast, reliable access to genuine replacement parts and commercial off-the-shelf components through an established network of suppliers, strategic inventory programs, and shared regional warehousing. Leveraging extensive knowledge of equipment build history, configurations, and component requirements, we help quickly identify and source the right parts while supporting nuclear quality requirements.
Obsolescence Management & Lifecycle Planning
Staying Ahead of End-of-Life Components
Proactively identify components that are discontinued, approaching end of life, or becoming difficult to source. Through lifecycle reviews and obsolescence assessments, facilities gain visibility into emerging risks before they impact operations. Our specialists can recommend direct replacements, retrofits, redesigns, or alternative sourcing solutions that reduce downtime risk and support long-term asset reliability.
Inventory Analysis & Optimization
Unlocking Greater Value from Your Spare Parts Inventory
Evaluate spare parts programs to identify shortages, excess stock, and optimization opportunities across systems and facilities. Through inventory assessments and criticality analysis, facilities gain actionable recommendations to improve parts availability, reduce carrying costs, and support faster recovery when failures occur.
