Global market valuation was derived through contract value mapping and decommissioning project pipeline analysis. The methodology included:
Identification of 40+ key service providers across North America, Europe, Asia-Pacific, and emerging nuclear markets
Project mapping across PWR, BWR, GCR, and other reactor types, segmented by immediate dismantling versus deferred dismantling strategies and capacity categories (Up to 800MW, 801MW-1000MW, Above 1000MW)
Analysis of reported and modeled annual contract values specific to decommissioning portfolios, including immediate dismantling contracts, spent fuel management, and site restoration services
Coverage of service providers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (announced reactor retirement timeline × estimated decommissioning cost by reactor type and region) and top-down (major contractor revenue validation) approaches to derive segment-specific valuations for immediate versus deferred dismantling strategies and capacity-based market sizing
