The DIstributed Sensing for COrium Monitoring and Safety (DISCOMS) project considers the use of optical fiber sensing cables embedded into the concrete floor under the reactor vessel for remote monitoring of a severe nuclear accident. This presentation focuses on the selection and testing of single-mode optical fibers with limited radiation-induced attenuation (RIA).
