Radiation Resilient Ultrasonic Sensors (RRUS)

有限的通道和高厚度部件通常将核工业中的无损检测限制为超声波检测(UT)技术。商业上可获得的UT传感器的辐射耐受性被限制在1至2 mGy累积剂量，即使是品牌为抗辐射的型号。由于传感器意外故障，可能会出现严重的操作困难，而且反复更换传感器既耗时又昂贵。RRUS项目将探索建造和测试新型的、抗辐射的、由外来材料制造的探测器和各种组装技术。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)在裂变核反应堆附近进行高辐射检查；b)在核废料处置场进行低辐射检查。我们的主要目标是制造和测试一系列原型探头，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.
