Nuclear power plants accidents should be seen as very complex issues, once they encompass environmental and social aspects that must be integrated to sustain appropriate management measures in a potential disaster event. Therefore, emergency plans require sounds spatial information knowledge and the interactions of their environments. The herein study aims to contribute to the emergency plans, especially to the possible evacuation routes identification for a Nuclear Power Plant located in Angra dos Reis, Brazil. The study was conducted within 120 km radius around the power plant. Results indicate that evacuation plans should be elaborated for the urban cores with low roads availability, or even for high population density areas, that in spite of being well served by alternative routes, exhibit increased road traffic and population flow. These results present important information to provide support to local emergency management actions and guidelines, playing a key role to assist on the evacuation planning.

巴西安格拉杜斯雷斯，Almirante Alvaro Alberto核电站周围地区的城市住区和道路网络分析

核电厂事故一旦包含环境和社会方面的问题，必须将其综合起来以在潜在灾难事件中维持适当的管理措施，就应将其视为非常复杂的问题。因此，应急预案需要健全的空间信息知识及其环境之间的相互作用。本文的研究旨在为应急计划做出贡献，特别是为位于巴西安格拉杜斯雷斯的核电站可能的疏散路线识别做出贡献。该研究是在电厂周围120公里半径内进行的。结果表明，应当为道路通行能力低，甚至人口密度高的城市中心制定疏散计划，尽管有替代路线，但疏散计划仍会增加道路交通和人口流量。
