The ION model provides a scalable framework for aligning strategy, technology, workforce, and operations across the enterprise. ScottMadden’s role is translating this framework into practical implementation. Working with Idaho National Laboratory (INL) and nuclear utilities, we’ve turned the ION approach into rigorous methodologies that can be applied to deliver fleetwide transformations. Figure 1 illustrates how successful ION implementation requires coordinated transformation across all organizational dimensions. Technology deployment must align with workforce enablement, process redesign, and governance evolution to deliver sustainable results. Our methodologies address each of these dimensions systematically.

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, quantifying potential savings of $60 million annually at a typical dual-unit plant. [1] We’ve also developed structured approaches for assessing how ready plants are for 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 digital 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.

Through numerous ION implementations, consistent patterns have emerged that separate successful transformations from failed initiatives:

1. 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 only deliver value when embedded in redesigned work processes, redefined roles, and new decision-making structures. Technology enables transformation but doesn’t drive it.
2. Build Scalable Fleet Governance. Programs with cross-functional oversight and clear standards move faster and deliver better results than plant-by-plant efforts. Without enterprise governance protocols for investment decisions and implementation standards, modernization becomes an inconsistent patchwork that fails to capture fleetwide benefits.
3. Design in Cybersecurity and Compliance. With NRC’s Cybersecurity Rule enforcement intensifying, security architecture must be built into modernization from the start. This includes critical digital asset classification and hybrid OT-IT readiness. Retrofitting security after implementation creates delays, cost overruns, and compliance risks.

Ground Business Cases 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.

ScottMadden brings deep technical expertise and operational experience to support nuclear operators through the complete ION transformation journey. Our Generation and Operational Technology practices partner with clients to deliver transformation that is practical, scalable, and aligned with regulatory requirements.

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 modernization can move from road map to reality.

Figure 2 illustrates ScottMadden’s ION modernization pathway, progressing from initial assessment through fleetwide implementation. This structured approach ensures each phase builds on the previous, creating momentum and reducing implementation risk.

ScottMadden delivers ION transformation through six integrated focus areas that address every aspect of modernization. As shown in Figure 3, our technical insight, operational discipline, and enterprise change leadership work together to create comprehensive transformation solutions.

• Capital planning and investment scenario modeling
• Cost-benefit analysis for digital infrastructure, I&C control system upgrades, and predictive maintenance technologies
• Regulatory strategy and rate case approach, licensing support, and integration with digital modernization filings

• Secure data infrastructure planning for hybrid operations
• NRC Cyber Rule readiness assessments and critical digital asset classification
• Cybersecurity architecture design and owner’s engineer support for digital systems

• NXT GEN® training, workforce strategy, and digital training program design
• Organizational redesign for integrated operations, human-system interface optimization, and mobile workforce enablement

The future of nuclear power requires comprehensive transformation, not isolated upgrades. Success demands an integrated approach that aligns operations, digital strategy, and organizational capabilities at fleet scale.
