We report the results of a long-term exposure of fiber Bragg gratings in the BR1 low-flux nuclear reactor at SCK·CEN in Mol, Belgium. Gratings fabricated in the photosensitive and the standard fibers were installed in February 2000 in a research channel of the reactor and remained there until August 2008. During this time the reactor was operational 4690h so that the gratings received a total thermal/fast neutron fluence ~16.9/1.47 × 1017 n/cm2, and a gamma-dose ~10 MGy. The temperature cycled… CONTINUE READING
