Adam, At Millstone, we use a 2000 cfm HEPA which is attached to a charcoal unit. In front of both of these we use a moisture separator unit. The suction hose for this set up is attached to the opposite side of the generator that is being worked/entered. For example, when working the Hot Leg side, we attach the hose to the Cold Leg side, and vice versa. Also, we utilize an AMS-4 attached to the discharge side of the HEPA for airborne activity monitoring.

At Waterford 3 we have 2 U tube stream generators. What is your steam generator set up? What size CFM HEPA unit does your plant use for hooking up to steam generators? What is the minimum recommended size?
