1、RCC-M-Edition 2007 SECTION I：SUBSECTION A GENERAL RULES_GENERAL RULESSECTION I : SUBSECTION A DESIGN AND CONSTRUCTION RULESFOR MECHANICAL COMPONENTS OF PWRNUCLEAR ISLANDSRCC-MRCC-M - Edition 2007 Subsection A A 1000 OBJECTIVES AND STRUCTURE OF THE CODE A 1100 OBJECTIVES The design and construction r
2、ules applicable to mechanical components of PWR Nuclear Islands (RCC-M) are a part of the collection of design and construction rules for nuclear power plants. It covers the rules applicable to the design and manufacture of pressure boundaries of mechanical equipment of pressurized water reactors (P
3、WR). The pressure components subject to the RCC-M are specified in A 4000. They include the reactor fluid systems (primary, secondary and auxiliary systems) and other components which are not subject to pressure: vessel internals, supports for pressure components subject to the RCC-M, nuclear island
4、 storage tanks. When a pressure equipment is subject to the RCC-M, all its elements subject to pressure are also, in accordance with the provisions of A 4000, and these elements are the same class as the component. In this case all the provisions of the RCC-M are applicable: design, procurement, man
5、ufacture, inspection and pressure testing. Elements which are not subject to pressure and which are subject to the RCC-M may be covered within the Code by limited specific provisions (procurement of materials for example). The other rules applicable to this equipment must be in contractual form. The
6、 assemblies comprising pressure equipment assembled by a manufacturer to constitute an integrated and functional whole, shall be subject to the rules indicated in this Code. Main objectives of Code Requirements are to ensure the integrity and mechanical stability over the equipment design life. Func
7、tion ability and operability of equipment are not directly addressed in the Code. The RCC-M contributes to ensuring compliance with regulatory requirements. These requirements depend on the applicable regulatory context. For information purposes: - The correspondence between the essential safety req
8、uirements mentioned in annex 1 of European Directive 97/23/EC and the provisions of the RCC-M is given in annex ZZ of this Code. - The correspondence between annexes 1,2, 3 and 4 of the French Order dated December 12, 2005, and the provisions of the RCC-M is given respectively in chapters ZY1, ZY2,
9、ZY3 and ZY4 of annex ZY of this Code. - The provisions applicable by way of annex 1 of European Directive 97/23/EC are clarified in annex ZU. - The provisions applicable by way of the French Order dated December 12, 2005, are clarified in annex ZT. n 113-2007 A 1000 / 1 RCC-M - Edition 2007 Subsecti
10、on A Application to other regulatory frameworks must be covered by appropriate provisions in the equipment specification or in other documents specified by the contract. The RCC-M is representative of the state of the art as concerns the design and manufacture of PWR components, ensuring an overall
11、safety level tested through experience. A 1200 STRUCTURE A 1210 GENERAL STRUCTURE The RCC-M consists of five sections (See Table 1210.1), which provide rules for the design and construction process of equipment. Section I is divided into subsections providing specific rules for different component t
12、ypes and classes. SECTIONS II to V provide rules for the following technical fields: - Section II covers requirements for the procurement of parts and products. - Section III specifies rules for destructive testing and non-destructive examination. - Section IV specifies rules for the qualification a
13、nd performance of welding operations. - Section V specifies rules for manufacturing operations other than welding. SECTION I comprises subsections numbered alphanumerically: - Subsection A covers all general requirements relating to application of these rules. - Subsections B, C, D, E, G, H, J and P
14、 are applicable to: - TO PRESSURE COMPONENTS OF A GIVEN CLASS Subsection B applies to class 1 components, Subsection C applies to class 2 components, Subsection D applies to class 3 components. Each of these subsections covers vessels (vessels, heat exchangers), pumps, valves (excluding actuators) a
15、nd piping. - SPECIFIC COMPONENTS Subsection G applies to Reactor internals, Subsection P applies to Containment pipe penetration. A 1000 / 2 n 113-2007 RCC-M - Edition 2007 Subsection A - ALL CLASSES OF A GIVEN TYPE OF COMPONENT Subsection H: Supports, Subsection E: Small pressure components, Subsec
16、tion J: Low pressure or atmospheric storage tanks.

18、ON V - FABRICATION F A 1220 STRUCTURE OF SUBSECTIONS Subsections B, C, D, E, G, H and J have all the same general structure. - Chapter 1000 specifies the scope of the subsection, plus general provisions. Where the subsection has a specific structure, it is described in more detail in chapter 1000. -
19、 Chapter 2000 specifies the products and parts which may be used for the manufacture of components. - Chapter 3000 provides rules for design of components. The different subsections B, C, D, E, G, H, J include specific provisions with respect to design rules, allowable stresses and design requiremen
20、ts. - Chapter 4000 provides rules for fabrication and examination. n 113-2007 A 1000 / 3 RCC-M - Edition 2007 Subsection A - Chapter 5000 deals with items which are specific to the components covered in each subsection: tests for pressure components and storage tanks, approval of a standard for supp
21、ort, non destructive examination for reactor internals, pump qualification for small components. When necessary, the subsections of SECTION I refer specifically to the rules and technical requirements given in SECTIONS II to V, thereby making them applicable to the components concerned. To apply the
22、 RCC-M to a given component, the relevant subsections of SECTION I provide rules in the form of specific requirements or references to other sections (or to other subsections of SECTION I) which enable the Manufacturer to apply the requirements of the RCC-M to a specific component. The subsections o
23、f SECTION I are therefore the key and guide to the RCC-M. Subsection Z of SECTION I consists of annexes providing design rules or data, which are applicable to different component types and parts. Reference is made to these annexes in other subsections of SECTION I. Annexes are organised in two sets
24、: - Mandatory technical annexes: When specifically referred to by other chapters of this Code, the annexes numbered with Roman numerals are mandatory (Z.I, Z.II, Z.III, etc.). - Non mandatory technical annexes, referenced by letters. These annexes have been included to provide methods and practices
25、considered to be acceptable and in accordance with the general provisions of the other subsections of Section I. The requirements of annex ZS shall apply when explicitly required by the contract. - The annexes relative to French regulatory conformity (ZT, ZU, ZY and ZZ, cf. A.1100). It is permissibl
26、e to use other methods or practices not specified in the optional annexes, provided that it is demonstrated beforehand that these methods or practices meet the requirements and that the Contractor has given prior written permission.
