When I worked at Limerick in the turbine building the had 3 groups, who rotated with breaks, of specialty techs such electricians, welders, pipefitters etc. to me. So I would work supporting cutting into contaminated equipment and did my own surveys solo, counting smears etc. They would rotate with fresh people while I was constantly working. I literally had to sneak out for a 20 minute lunch break including travel time.
Another time while working at North Anna I spent 11 out of 12 hours in containment because they were short of people.
This was years ago, I see little changing as it is cheaper to overwork the HP's knowing most are a dedicated bunch than to hire enough to do the job safely.
