Abstract

Radiation resistant fused silica core optical fibers, 900 ppm OH doped and their hydrogen treated fibers with a plastic jacket, 18000 ppm OH doped one having very low optical transmission loss with a carbon jacket, and a fluorine doped fiber with a plastic jacket, were irradiated in a JMTR fission reactor, at 400±10 K with a fast neutron(E>1 MeV) flux of 3.2×1017 n/cm2s and a gamma dose rate of 3×103 Gy/s for 527 hours. Their optical transmission loss at 850 nm was measured in-situ during irradiation.
