Field testing of nuclear air cleaning systems at Duke Power Company

Duke Power has long been committed to protecting the health and safety of the public. This commitment is reflected in the design, testing and operation of nuclear air filtration systems. Duke Power considers nuclear air filtration as one of several vital means to protect the quality of the environment, not as an unnecessary evil that has been forced upon us by regulatory agencies. Nuclear air filtration has come a long way at Duke Power Company since the start-up of our first nuclear unit, Oconee 1 in 1973. Air filtration systems in all three Oconee units predate Regulatory Guide 1.52 and ANSI N509. In contrast, our Catawba Nuclear Station has nuclear air filtration systems built and testable to the latest codes, standards, and Regulatory Guides. It is in this wide range of filtration systems and experiences that practices and plans for the future are discussed
