That seems likely to degrade the fiber, or the signal and I'm having trouble thinking of any tested fiber in the range of a molten reactor core. The flux is really crazy near that thing, and not just photons, but relativistic electrons and some very angry helium nuclei.

Or you could put a scintillating detector in a lead ball with a hole, and scan by rotation and pipe the light from the scintillator out to external electronics. All you need is a long pipe installed to get started.
