Maybe tritium was a bi product? I just remember I went to a job interview there for Nuclear Security Forces position and they mention the reactor was different from the public's standard view of nuclear plants no big ass cooling tower and the main nuclear elements being produced in there reaction was tritium the stuff they use in weapon scopes and other things.

I never got the job I got hired and then they down sized the plants personel and went on a hiring freeze one of the big things was them getting all the nuclear material off site to New Mexico or at least that was what the local civilian population wanted the company wanted to build casks on site cause the property was never going to be public land
