Abstract

The crucial part of nuclear waste storage is the construction of sealing structures made of reliable, safe and well–understood materials. We present an extended analysis of long-term multi–sensory monitoring and non–destructive testing (NDT) inspection of two laboratory specimens aiming at potential materials for sealing structures for nuclear waste repositories. Specimens with a volume of 340 litres made from newly developed alkali–activated materials (AAM) and established salt concrete (SC) were analysed using embedded acoustic emission and wireless radio-frequency identification (RFID) sensors, ultrasonic echo imaging, active thermography, and X–ray computed tomography. The monitoring analysis showed lower heat of reaction and 50% less acoustic emission events in AAM compared to SC. However, due to the surface effects of the AAM material, the number of acoustic emission events increased significantly after approximately two months of monitoring. Subsequently performed NDT inspections reliably located embedded sensors and confirmed the absence of major cracks or impurities. The presented laboratory results show the feasibility and potential of comprehensive NDT monitoring and inspection to characterise cementitious and alternative materials as well as the need for multi–parameter long–term monitoring. Thus, our study demonstrates that tailored NDT investigations will help to develop safe sealing structures for nuclear waste repositories.

混凝土工程屏障系统新材料的多感官监测和无损检测
核废料贮存的关键部分是使用可靠、安全和易于理解的材料建造密封结构。我们介绍了对两个实验室试样的长期多感官监测和无损检测(NDT)的扩展分析,这些试样是核废料贮存库密封结构的潜在材料。使用嵌入式声发射和无线射频识别(RFID)传感器、超声回波成像、有源热成像和 X 射线计算机断层扫描,对新开发的碱活性材料(AAM)和成熟的盐混凝土(SC)制成的 340 升试样进行了分析。监测分析表明,与盐拌混凝土相比,AAM 的反应热更低,声发射事件减少 50%。然而,由于 AAM 材料的表面效应,声发射事件的数量在大约两个月的监测后显著增加。随后进行的无损检测可靠地确定了嵌入式传感器的位置,并确认不存在重大裂缝或杂质。所提供的实验室结果表明,通过全面的无损检测监控和检查来确定水泥基材料和替代材料的特性是可行的、有潜力的,同时也表明需要进行多参数的长期监控。因此,我们的研究表明,有针对性的无损检测调查将有助于为核废料储存库开发安全的密封结构。
