Research Summary: An ecology of participation for fusion energy development

Research indicates that future fusion energy deployment decisions—including waste production, tritium management, safety, and impacts on local communities—are fundamentally sociotechnical rather than purely technical. Drawing from historical conflicts in nuclear fission where top-down decision-making sparked sustained public resistance, the paper argues that opposition stems from place-specific socio-economic and environmental concerns rather than an informational deficit, urging fusion developers to deploy an 'ecology of participation'.

Why it matters

Securing social license is as critical to the viability of fusion energy as resolving technical milestones. Without proactive, multi-modal engagement models, the sector risks repeating the protracted siting battles and regulatory delays that compromised fission deployment. Establishing participatory frameworks early aligns technological development with community priorities and long-term institutional legitimacy.

Key insights

• Decisions shaping fusion facilities regarding waste, tritium, safety, and community impacts are sociotechnical in nature.
• Historical energy technologies like fission faced sustained public resistance due to top-down decision-making models.
• Public opposition is driven by place-specific environmental, health, sociocultural, and economic concerns, as well as institutional distrust, rather than a lack of public understanding.
• Fusion developers have an opportunity to avoid past missteps by adopting an 'ecology of participation' featuring multiple complementary participatory modalities.
