Subsection NCA provides the general requirements for both Divisions 1 and 2 of Section III. It is applicable to all Classes of construction, covering steel vessels, storage tanks, piping, pumps, valves, core support structures, and concrete containment vessels. This chapter identifies how to classify components and how the jurisdictional boundaries of Section III define what is within and outside the scope of the Code. It discusses the use of Code Editions, Addenda, and Code Cases, and the requirements for Design Basis, Design and Construction Specifications, and Design Reports. The chapter addresses the responsibilities and Quality Assurance Program requirements of the different entities involved in constructing a nuclear power plant, from the manufacturer of materials to the Owner. Requirements for ASME accreditation, application of the ASME Code Symbol Stamp, and use of Code Data Reports are also described. The chapter then outlines the basis for exemptions, load combinations, responsibilities of the different entities involved in nuclear power plant construction, Certificate of Authorization Holders, and Quality System Certificate Holders. Finally, it provides cross-referencing to other Code Sections and Subsections, such as Sections III and XI, as well as to pertinent Regulatory Guides, such as the U.S. Code of Federal Regulations.
