Hi Harry, DC Cook-1,2 mechanically degases The majority of US PWRs in the country ues mechanical degas, and do not perform chemical degas as Braidwood does.
Our purpose of mechanical degas it to ensure that we minimize the amount of gas generation from forced oxygenation, which is known to partition small particles into the RVH head and raise dose rate. I know a large number of plants that mechanically degas management program are: Beaver Valley-1,2 Chemist Don Salera Turkey Point 3,4 Paul Skinner Surry-1,2 Darlene Brock Davis Besse ? Vince Capozziello Point Beach-1,2, Jamie Pierce St. Lucie-1,2 Chip Bach Farley-1,2 Stan Varnum R.E. Ginna, Sharyl SNowden Calvert Cliffs 1,2 Jeff York VC Summer, Melissa Harmon There are many others. This method is a key element to our source term reduction program at Cook to enable 3 refueling outages below 37 personrem. Regards David W. Miller Radiation Protection Dept.
