Linear entity at the origin of the risk of a PPR terrain movement (Céton PPRI) in the department of Orne

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 zone.- source: DDT61/SACR/PR- validité:01/01/2002风险源指的是一类现实实体，该实体的存在即代表潜在风险。该风险源可通过名称进行表征，在部分情形下，还可通过用于定位该风险源实体的地理对象来补充描述。该实体的位置与危险现象的相关认知，可用于划定风险池（risk pools）——即支撑RPP运行的风险暴露区域。对于核电厂（Nuclear Power Plants，NPPs）而言，此类实体例如可对应河流、地质不稳定区域。——来源：DDT61/SACR/PR，生效日期：2002年1月1日
