Map Viewing Service (WMS) of the dataset: Linear entity at the origin of the FNIRP risk of the Arrow in Sarthe.

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the hazardous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.For NPPs, this entity may, for example, correspond to a river, a geologically unstable area.风险源是指一类现实实体，其存在本身即构成潜在风险。该风险源可通过名称进行表征，在部分情形下还可借助指向该风险实际来源实体的地理对象完成标识。实体的位置信息与危险现象的相关知识，可用于定义风险池——即支撑RPP的风险暴露区域。对于核电厂（NPPs）而言，该实体可对应为河流、地质不稳定区域等。
