I don't know what is happening at West Valley now (I worked there 3 years ago), but I will describe my experience and state it is only one person's opinion. It is true Mark has some sway there which seems inappropriate for a tech to have; if you are not a friend do not expect to stay long.
Weather: It is brutal, a land of extremes. In winter, it snows from December to May, and gets down to -5 for weeks at a time. It is so cold even with gloves you will feel pain no matter how warm you dress. In summer, it is humid and you need an a/c running to sleep or you will be in a constant state of sweatting.
When I was there they had this super-emphasis on having over 2 million hours of no loss time work. It was an illusion for if you ever got hurt they would lay you off rather than admit they broke that record.
There is no excuse for the foot dragging on cleaning the place up. If Rocky Flats could be cleaned up, this placed should have been done years ago. They occasionally remove a building and lay off some permanent people to try to show progress. If the DOE really wanted to clean the site up, they would lay everyone off, including the management and start fresh with non-local people who really wished to finish the job.
I could say more, but I find the management there is punishing themselves more on there own than anything I could say. If you go there, just keep you commitments temporary and be ready to leave at a drop of a hat if more suitable job is found elsewhere.
