Abstract:

Under the dual-carbon and high-quality development agenda, areas surrounding nuclear power plants have emerged as tourism destinations integrating nuclear science popularization with regional economic activities. However, expanding tourism scale increases population density and mobility, thereby intensifying the complexity and operational burden of off-site nuclear emergency management. This creates an inherent trade-off between tourism development and emergency safety, making it essential to determine an appropriate tourism scale under institutional safety constraints. From a government decision-making perspective, this study formulates the problem as a joint optimization of tourist scale, spatial distribution, and emergency infrastructure investment under constraints of ecological capacity, tourism resources, and emergency preparedness systems. A safety margin indicator, defined as the ratio of emergency response capacity to exposed population, is introduced and decomposed into evacuation and decontamination components. A mixed-integer multi-objective optimization model is developed to simultaneously maximize comprehensive benefits and safety margins. Comprehensive benefits integrate economic, employment, and science popularization effects, while safety margins are derived from the comparison between system capacities and emergency demand. The model incorporates constraints such as ecological carrying capacity, accommodation limits, and emergency response time. Due to the NP-hard nature and conflicting objectives, an NSGA-II-based approach is employed, with pre-simulated evacuation and decontamination capacities embedded to reduce the search space. A case study based on a coastal nuclear power plant in China is conducted under three accident scenarios. Results show that: (1) a stable trade-off exists between benefits and safety; (2) coordinated multi-objective optimization significantly improves safety with limited benefit loss; (3) tourist structure and spatial allocation critically affect outcomes; and (4) optimizing composition and distribution is more effective than simply reducing tourist numbers. This study provides an integrated decision-support framework linking tourism development with nuclear emergency management, offering practical insights for sustainable development in high-risk energy regions.
