SSPC QN 1
SSPC QN 1, Nuclear Coating Supplement
This supplemental procedure describes a method for evaluating the primary qualifications of industrial coating contractors that perform work in nuclear power plant and shop facilities that coat parts or components for installation in primary containment or other safety-related areas of light-water nuclear power plants. It defines a minimum standard for qualification.
The QN 1 procedure encompasses the field application of protective coatings for corrosion control and decontaminability of concrete, non-ferrous metal, and steel surfaces in Service Level I and III areas of nuclear power plant facilities. It also covers the shop application of coatings for parts and components to be installed in Service Level I and III areas.
The requirements of this procedure are intended to supplement the requirements of SSPC-QP 1 (field application of steel surfaces), SSPC-QP 3 (shop painting in a fixed facility), and SSPC-QP 8 (field application of concrete surfaces). Contractors seeking qualification to SSPC-QN 1 (Nuclear Coatings Supplement) must first be qualified in good standing to the appropriate core qualification (i.e., QP 1, QP 3, or QP 8), depending upon the type of coating work performed.
