Safety1,
The Candu plants use bubble suits that are reusable, closed with zippers, and two-piece. The allow very little loose contamination there, the bubbles are to protect against tritium, which is absorbed through skin as well as inhaled.
It takes very little time to put one on compared to the disposable ones we use, cause they don't need duct tape. I've actually seen guys use them where they were not required, just to keep cool. They just put them on without the hood.
The hood they use is a disposable tyvek pullover shirt with a hood that is exactly like the MSA PAPH, except it has a little window that they don't seal shut until they are plugged into air.
When they are done, they toss the hood, and take off the suit in a disolvable bag. The suit is laundered bag and all, then reused.
The air manifold goes throughout the suit, and the air & headphone connections are built into the suit. They would be great to use here except that they weigh about five pounds each, and we would contaminate them so much that they probably couldn't be reused.
This Delta suit, if it is being used in Canada, could probably be reused there too, since you don't have to destroy it to get it off, and they don't get crapped up. (A green man actually made me wear a tyvek suit over one to keep it clean)
