Dataset Direct Download Service (WFS): Risks of PPRT Argos in Beaune la Rolande

Area exposed to one or more hazards represented on the hazard map used for risk analysis of the RPP. The hazard map is the result of the study of hazards, the objective of which is to assess the intensity of each hazard at any point in the study area. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The assignment of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity.For PPRTs the hazard levels are determined by effect effect on maps by type of effect and overall on an aggregated level on a synthesis map.All hazard areas represented on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered to be subject to hazard (cases of breakage or inadequacy of the structure).The hazard zones may be classified as data compiled in so far as they result from a synthesis using several sources of calculated, modelled or observed hazard data. These source data are not covered by this class of objects but by another standard dealing with the knowledge of hazards.Some areas of the study perimeter are considered “zero or insignificant hazard zones”. These are the areas where the hazard has been studied and is nil. These areas are not included in the object class and do not have to be represented as hazard zones.本类区域指适用于反应堆保护方案（RPP）风险分析的灾害地图（hazard map）上标注的、受一种或多种灾害影响的区域。灾害地图是灾害专项研究的成果，其核心目标为评估研究区域内任意点位的各类灾害强度。该评估方法因灾害类型而异，最终将在研究范围内划定若干区域，形成按灾害等级分级的分区体系。在研究区域内指定点位分配灾害等级时，需综合考虑危险现象的发生概率及其强度等级。针对PPRTs，灾害等级按影响类型分别在对应地图上确定，并在综合地图上以聚合层级的形式整体标注。灾害地图上标注的所有灾害影响区域均需纳入本类范畴。受防护结构保护的区域也需以特定方式（若有必要）标注，因为此类区域仍可能因结构损毁或防护不足而面临灾害风险。灾害区域可归类为经汇总的数据集，前提是此类区域基于多源计算、建模或观测得到的灾害数据综合生成。此类源数据不属于本对象类别的覆盖范围，而应由另一项针对灾害认知的标准进行规范。研究范围内部分区域被划为“零灾害或可忽略灾害区域”，即经研究确认灾害风险为零的区域。此类区域不属于本对象类别的范畴，无需作为灾害区域进行标注。
