摘要
El Cabril储存库的设计寿命为300-500年,因此,这些结构的完整性应该比我们在钢筋混凝土结构上的经验要长得多。由于缺乏超过100-150年历史的结构的记录,这对核废料处理的设计提出了挑战,并要求进行更具体的研究,试图预测其长期行为。为了研究混凝土的实际现场老化,Enresa与IETcc和Geocisa合作开展了一项监测计划,在试点核废料容器中安装永久性传感器。这些传感器于1995年安装,用于监测耐久性参数。本文介绍了1995年以来在西班牙El-Carbril-Spain储存库中实际埋藏的试验容器中腐蚀参数的演变情况。应用的无损检测(NDT)基于电化学和机械测量(腐蚀速率、腐蚀电位、电阻率、混凝土应变、氧气可用性)。给出了气候影响与腐蚀参数之间的关系。结果表明,温度是影响测量结果的一个非常相关的变量。进一步分析了腐蚀随时间的变化规律。
Environmental influence in the corrosion parameters registered in a buried pilot nuclear waste container
The El Cabril repository has a design life of 300-500 years and therefore, these structures should keep its integrity much longer than the back experience we have on reinforced concrete structures. This lack of record on structures older than 100-150 years makes a challenge the design of nuclear waste disposals and calls for more specific studies to try to anticipate the long term behavior. In order to study the real on-site aging of concrete, Enresa has undertaken a monitoring program in collaboration with IETcc and Geocisa by the installation of permanent sensors in a pilot nuclear waste container. These sensors were installed in 1995 for monitoring durability parameters. In the paper the evolution from 1995 of corrosion parameters obtained in a pilot container buried in real conditions in the repository of El-Carbril-Spain is presented. The non destructive tests (NDT) applied are based in electrochemical and mechanical measurements (corrosion rate, corrosion potential, electrical resistivity, concrete strains, oxygen availability). Relations between the climatic influence and the corrosion parameters are also presented. The results indicate that the temperature is a very relevant variable influencing the measurements. Some further analyses are given on the behavior with time of the corrosion.
