Radiation Resilient Ultrasonic Sensors (RRUS)

有限的接近和高厚度部件通常将核工业中的无损检测限制为超声测试（UT）技术。市售UT传感器的辐射耐受性仅限于1至2 MGy的累积剂量，即使是品牌为抗辐射的型号。由于意外的传感器故障，可能会出现严重的操作困难，并且经常更换传感器既耗时又昂贵。RRUS项目将探索由外来材料和各种组装技术制造的新型辐射弹性探针的构建和测试。这一目标将为核工业提供可靠的UT解决方案，用于长期检查和监测。设想了两种情况：a）高辐射-在裂变核反应堆附近进行视察; B）低辐射-在核废料处置场进行视察。我们的主要目标是制造和测试一系列定制的原型探头，以确定最适合每种条件的设计。

Limited access and high thickness components typically limit non-destructive inspection in the nuclear industry to Ultrasonic testing (UT) techniques. Radiation endurance of commercially available UT sensors is limited to cumulative doses of 1 to 2 MGy even for models branded as radiation resistant. Severe operational difficulties can occur due to unexpected sensor failure and recurrent sensor replacement is both time consuming and expensive. The RRUS project will explore the constructed and testing of novel, radiation resilience, probes manufactured from exotic materials and a variety of assembly techniques. This goal will be to provide the nuclear industry with a reliable UT solution for prolonged inspection and monitoring. Two scenarios are envisaged: a) high radiation - inspection close to fission nuclear reactors and b) low radiation - inspection in nuclear waste disposal sites. Our main objective is to manufacture and test a series of prototype probes tailored to determine the design most suited to each condition.
