This was part of the TMI compute facility retrofits.  Large facilities at each plant were required to be built at least 2 Klicks away with Health Physics ( rad medicine ), simulators, data collection, etc.   We had full take offs of all data that went to the control rooms collected and displayed in the remote facilities.   They were time and materials contracts and _very_ lucrative..  All because something was printed on yellow paper instead of pink...

We have to use expensive shielded cabling on some of our waste water projects...poop gas goes boom...

    I also seem to recall that fiber is more likely to degrade in
    space due
    to radiation.   We had issues with fiber runs from Nuke plants
    having to
    be heavily shielded when it was near the containment and not in
    man-spaces..  But this was in 1980 when fiber was a pretty new tech..
