ABSTRACT Degradation of UV transmitting optical fibers under nuclear reactor neutron exposure is reported. Four type of optical fibers (solarization resistant, H2-loaded; UV transmission standard OH; UV enhanced transmission, high OH, H2-loaded; high OH, deep UV enhanced) were exposed to neutron fluences up to 4 x 1017 n/cm2. The optical transmission was measured off-line over the 200 nm – 900 nm spectral range and the build-up of color centers was monitored.
