We’ve analyzed opportunities across nuclear operations to identify where changes in technology, processes, and workforce deployment can reduce costs while maintaining safety. This research catalogued specific improvements, ranging from remote monitoring to automated maintenance planning, and quantified potential annual savings of $60 million at a typical dual-unit plant. [1] We’ve also developed structured approaches for assessing how ready plants are for transformation (Digital Modernization, NRC Cybersecurity Compliance, Fleet-Wide Transformation). These approaches evaluate current business conditions, workforce challenges, and equipment obsolescence then compare existing initiatives against proven practices. The result is customized roadmaps that balance quick wins with strategic initiatives based on each plant’s specific situation.[2]
Finally, we’ve created rigorous methods for building modernization business cases that capture both immediate returns and long-term strategic value. At Vistra’s Comanche Peak, we developed a business case, demonstrating NPV of $74 million over 30 years (increasing to $685 million over 50 years) for comprehensive I&C upgrades, with payback in under 18 years. Critical to these results was properly accounting for the true cost trajectory of maintaining obsolete systems. At Constellation’s Limerick plant, our analysis revealed that obsolete safety-related I&C equipment costs escalate by more than 20% annually—far exceeding standard inflation assumptions of 3% to 5%.[3] This finding fundamentally changes modernization economics—what appears marginal under traditional assumptions becomes compelling when true obsolescence costs are recognized.
Implementation Insights: Four Keys to a Successful ION Operating Model
Through numerous ION implementations, consistent patterns have emerged that separate successful transformations from failed initiatives:
- Lead with Operating Model Design, Not Technology. The most successful efforts solve specific operational problems rather than deploy technology for its own sake. Digital tools deliver value only when embedded in redesigned work processes, redefined roles, and new decision-making structures. Technology enables transformation but doesn’t drive it.
- Build Scalable Fleet Governance. Programs with cross-functional oversight and clear standards move faster and deliver better results than on a plant-by-plant basis. Without enterprise governance protocols for investment decisions and implementation standards, modernization becomes an inconsistent patchwork that fails to capture fleetwide benefits.
- Design in NRC Cybersecurity and Compliance. As NRC’s Cybersecurity Rule enforcement intensifies, security architecture must be built into modernization from the outset, avoiding the need for retrofitting. This includes critical digital asset classification and hybrid OT-IT readiness. Retrofitting security after implementation creates delays, cost overruns, and compliance risks.
Ground Business Case Development in Operating Reality. Executives and regulators demand proven value, not projections. Successful business cases use actual plant data on labor costs, maintenance expenses, and obsolescence trends. Early wins with measurable results build momentum and unlock further investment.
Comprehensive Support for Nuclear Modernization: Strategy Through Execution
We understand how to align modernization efforts with licensing requirements, cost recovery pathways, and internal investment governance. Our ability to connect strategy, engineering, IT, and regulatory realities ensures that modernization can move from roadmap to reality.
Figure 2 illustrates ScottMadden’s ION Operating Model Pathway, progressing from initial assessment through fleetwide implementation. This structured approach ensures that each phase builds on the previous one, creating momentum and reducing implementation risk.
