Integrated segmentation intelligence connecting service typologies, project phases, reactor designs, waste classifications, and ownership models to inform tailored decommissioning approaches

Understanding how services, project phases, reactor types, waste classifications, and ownership models intersect is central to designing responsive decommissioning strategies. Based on service type, decommissioning workstreams are organized across dismantling and demolition, planning and consulting, site restoration, and waste management. Dismantling and demolition itself encompasses both manual dismantling and mechanical dismantling approaches, each suitable to different radiological and structural conditions. Planning and consulting activities include feasibility studies and regulatory compliance work that define the legal and technical pathway for each project. Site restoration covers land remediation and landscaping objectives that determine end-state requirements, while waste management strategies balance offsite treatment options against onsite treatment capabilities.

Across project phases, operations move from decontamination through dismantling, onto post decommissioning surveillance, site restoration, and waste processing. Each phase has distinct technical, regulatory, and resource implications, requiring tailored competencies and transition planning. Reactor type matters because the reactor design influences radiological inventory, component complexity, and decommissioning sequencing; common reactor types include boiling water reactors, fast breeder reactors, gas cooled reactors, heavy water reactors, and pressurized water reactors, and each presents unique dismantling challenges.

Waste type classifications-high level waste, intermediate level waste, and low level waste-drive containment, transport, and disposal strategies, shaping both immediate handling requirements and long-term stewardship obligations. Finally, ownership models, whether government owned or private owned, affect funding mechanisms, public accountability, and the pace at which decisions can be executed. Integrating these segmentation dimensions yields a more nuanced approach to contractor selection, risk allocation, and technical pathway optimization.
