8 SUBSUBPARAGRAPHS Subsubparagraphs are designated by adding lowercase letters in parentheses to the major subparagraph numbers, such as NB-1132.1(a). When further subdivisions ofminor subparagraphs are necessary, subsubparagraphs are desig- nated by adding Arabic numerals in parentheses to the subparagraph designation, such as NB-2121(a)(1). 9 REFERENCES References used within Section III generally fall into one of the following four categories. (a) References to Other Portions of Section III. When a reference is made to another Article, Subarticle, or para- graph, all numbers subsidiary to that reference shall be included. For example, reference to NB-3000 includes all material in Article NB-3000; reference to NB-3200 includes all material in Subarticle NB-3200; reference to NB-3230 includes all paragraphs NB-3231 through NB-3236. (b) References to Other Sections. Other Sections referred to in Section III are the following: (1) Section II, Materials. When a requirement for a material, or for the examination or testing of a material, is to be in accordance with a specification such as SA-105, SA-370, or SB-160, the reference is to material specifica- tions in Section II. These references begin with the letter “S.” (2) Section V, Nondestructive Examination. Section V references begin with the letter “T” and relate to the nondestructive examination of material or welds. (3) Section IX, Welding and Brazing Qualifications. Section IX references begin with the letter “Q” and relate to welding and brazing requirements. (4) Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components. When a reference is made to inservice inspection, the rules of Section XI shall apply.
(3) Dimensional and other types of standards cov- ering products such as valves, flanges, and fittings are also published by the Manufacturers Standardization Society of the Valve and Fittings Industry and are known as Standard Practices. When a product is required by these rules to conform to a Standard Practice, for example MSS SP- 6, the Standard Practice referred to is published by the Manufacturers Standardization Society of the Valve and Fittings Industry, 127 ParkStreet, N.E., Vienna, VA 22180. The applicable year of issue of such a Standard Practice is that suffixed to its numerical designation in Table NB- 3132-1, for example MSS SP-6-1963. (4) Specifications for welding and brazing materials are published by the American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33135. Specifications of this type are incorporated in Section II and are identified by the AWS designation with the prefix “SF,” for example SFA-5.1. (5) Standards applicable to the design and construc- tion of tanks and flanges are published by the American Petroleum Institute and have designations such as API-620 and API-2000. When documents so designated are referred to in Section III, they are standards published by the Ameri- can Petroleum Institute. (d) References to Appendices. Two types ofAppendices are used in Section III and are designated Mandatory and Nonmandatory. (1) Mandatory Appendices contain requirements which must be followed in construction; such references are designated by a Roman numeral followed by Arabic numerals. References to II-1100 or XI-3212, for example, relate to the Mandatory Appendices. (2) Nonmandatory Appendices provide information or guidance for the use of Section III; such references are designated by a capital letter followed by Arabic numerals. Areferenceto D-1100, forexample, relates to aNonmanda- tory Appendix.
(b) The rules are not intended to be applicable to valve operators, controllers, position indicators, pump impellers, pump drivers, or other accessories and devices, unless they are pressure retaining parts or act as core support structures or supports. If such items are in a support load path, the provisions of NF-1100 apply. (c) The rules ofthis Section do not apply to instruments, or permanently sealed fluid filled tubing systems furnished with instruments, but do apply to instrument, control, and sampling piping when specified in Design Specifications. (d) Auxiliary systems for concrete containments that are required to assure functional adequacy of the vessels in accordance with the requirements ofthe Design Specifi- cation, including but not limited to concrete cooling sys- tems, thermal insulation, corrosion protection, leakage monitors, and strain monitoring systems, must be deline- ated fully by appropriate performance, reliability, and test requirements. These rules are not intended to otherwise be applicable to auxiliary systems. NCA-1140 USE OF CODE EDITIONS, ADDENDA, AND CASES (a) (1) Under the rules of this Section, the Owner or his designee shall establish the Code Edition and Addenda to be included in the Design Specifications. All items of a nuclear power plant may be constructed to a single Code Edition and Addenda, or each item may be constructed to individually specified Code Editions and Addenda.
