拉曼分布式温度传感器（RNTH）为监测设想中的法国核废料深层地质处置库（称为“RNTH”）提供了特殊的优势。在这里，我们提出了实验研究如何在恶劣的环境中，如与H2或γ射线相关的性能演变。这两个都被证明是强烈影响的温度测量与RISK。我们表明，通过调整所用光纤的特性进行传感，我们可以限制其退化，但在将Rendezvous集成到Rendezvous之前，必须通过系统研究开发额外的硬化。
Raman Distributed Temperature Sensors (RDTS) offer exceptional advantages for the monitoring of the envisioned French deep geological repository for nuclear wastes, called Cigéo. Here, we present experimental studies on how the performances of RDTS evolve in harsh environments like those associated with H2 or γ-rays. Both of them are shown to strongly affect the temperature measurements made with RDTS. We showed that by adapting the characteristics of the used fiber for the sensing, we could limit its degradation but that additional hardening by system studies will have to be developed before integration of RDTS in Cigéo.
