Civil Engineering for CVNPA Power Plant

Abstract

Selection of the plant location was made by applying a point system to a list of desirable attributes for a nuclear plant site. The concrete external shell wall of the cylindrical vapor container is designed to resist internal pressure and thermal gradients and to serve as a biological shield. A metal liner is provided for gaseous containment instead of a steel container and a separate concrete biological shield wall. A steel plate dome acts to resist the internal pressure, provides gaseous containment and serves as the interior form for the biological concrete shielding. The service building contains special purpose areas not required for fossil fuel steam plants. Throughout the plant, special protective finishes are required in areas subjected to high level activity where liquids are in contact with the surface and in areas subjected to spillage of liquids containing radioactive products. Finishes used include metal liners, plastic coatings, vinyl sheets and special paints, some of which require special surface preparation and application procedures.
