Colorado's Ft. St. Vrain nuclear power safety history

One advantage of being old is the ability to tap into old memories.  If my memory serves me, reporters are missing the story behind why the Colorado power plant ceased generating electricity by nuclear energy  while it was still young. I have heard TV media reporters repeat what must be the industry line: it was not economical to do so.  I believe that it was due to the fallout from Chernobyl.  The type of the two plants were so similar, that there was fear that the Chernobyl disaster could happen here.  It is worth diving into old newspaper archives to which I do not have access instead of just taking Public Service's or the current owner, Excel's, word for it.
