1、RCC-M-Edition 2007 SECTION I：SUBSECTION J STORAGE TANKS_STORAGE TANKSSECTION I : SUBSECTION J DESIGN AND CONSTRUCTION RULESFOR MECHANICAL COMPONENTS OF PWRNUCLEAR ISLANDSRCC-MRCC-M - Edition 2007 Subsection J J 1000 GENERAL J 1100 INTRODUCTION Under application of the requirements of A 4000, in part
2、icular A 4330, subsection J is applicable to low-pressure or atmospheric storage tanks. However, in its present form, subsection J only applies to tanks corresponding to the characteristics specified in J 1210. For tanks not meeting the above conditions, the design rules developed within better adap
3、ted codes may be used. Subchapter J 1200 specifies the scope of subsection J. Subchapter J 1300 gives the storage tank classification rules. Subchapter J 1400 distinguishes between the various types of tanks considered in this subsection. Subchapter J 1500 defines the documents to be established for
4、 this subsection. Subsection J 1600 defines the identification methods for parts and welded joints. Chapter J 2000 sets rules for selection of materials used in component parts. Chapter J 3000 sets rules for design of equipment. Chapter J 4000 sets rules for manufacturing components and their parts
5、for the examinations to be performed during and following manufacture. Chapter J 5000 describes hydrostatic tests for finished components. J 1200 SCOPE OF APPLICATION J 1210 GENERAL Subsection J applies to storage tanks complying with the following conditions: - tanks forming a surface of revolution
6、 with the vertical axis, - made of steel, parts assembled by welding, n 113-2007 J 1000 / 1 RCC-M - Edition 2007 Subsection J - construction located on a rigid foundation*, - fixed self-supporting roof, - diameter not greater than 18 metres. - gas layer pressure less than 100 kPa (1 bar). * The term
7、 rigid is used in the sense that subsection J is not applicable to tanks erected on loose soil or on a loose surface simply covered with a coating of concrete. J 1220 SCOPE LIMITS BETWEEN A TANK AND ITS SUPPORT J 1221 FLAT BOTTOMED TANK RESTING ON ITS FOUNDATION The scope of application of subsectio
8、n J extends to the support datum, between the tank and its foundation. J 1222 TANK RESTING ON THE FOUNDATION VIA THE INTERMEDIARY OF A SUPPORT ELEMENT This configuration occurs when the tank is connected to its foundation via the intermediary of a support element such as: - a circular skirt, - brack
9、ets welded to the tank, - posts directly linked to the tank. This support element is subjected to the requirements of subsection H. The scope limits of subsection J are consequently defined by the scope limits of subsection H (defined in ZH 1200). J 1230 SCOPE LIMITS BETWEEN TANK AND PIPING The scop
10、e of application for subsection J extends to the welded or mechanical connection with the piping. The welding link itself is produced in compliance with the requirements of subsection C or D according to the level of the piping. J 1300 CLASSIFICATION OF STORAGE TANKS The class of a low-pressure or a
11、tmospheric storage tank is determined by applying A 4332. J 1000 / 2 n 113-2007 RCC-M - Edition 2007 Subsection J J 1400 TYPES OF STORAGE TANKS In this subsection, two types of storage tanks are considered: - those in communication with the atmosphere (called atmospheric tanks) which are in constant
12、 contact with the external environment, - those at low pressure, isolated from external environment on a permanent basis, excluding safety devices limiting the relative pressure. J 1500 REQUIRED DOCUMENTS Chapter A 3000 defines these documents and describes their content. Documents required under th
13、is subsection J shall be kept at the disposal of Surveillance Agents. The contract shall specify which documents are to be handed over to the relevant parties. J 1510 EQUIPMENT DOCUMENTS The following documents shall be prepared for components falling within the scope of subsection J. Where producti

21、rence of the welder(s) or operator(s), . for automatic welding, the reference of the welding machine used. J 1000 / 4 n 113-2007 RCC-M - Edition 2007 Subsection J J 1523 NON-CONFORMANCE REPORT AND DEVIATION REPORT - See A 3700. J 1600 IDENTIFICATION J 1610 PURPOSE OF THE IDENTIFICATION SYSTEM The pa
22、rt or weld joint identification system is the means of unequivocally associating the part or weld joint with a given set of documents. J 1620 ADAPTATION OF IDENTIFICATION SYSTEM TO PRODUCTION CONTROL METHODS Identification procedures must therefore be adapted to the type of production control method
23、 applied to the part or weld: - control of individual items, using one identification number per item, - control by lot, using one identification number per lot. When a part is taken directly from stock and has only a steel grade number, the identification procedure set forth in this subsection shal
24、l not apply. J 1630 IDENTIFICATION METHODS Methods used to identify the components may include: - etching, - temporary marking (with ink, paint, etc.), - labelling, - routing slips. Identification methods and shop organization procedures shall be defined with a view to ensuring compliance with the o
25、bjective set under J 1610. J 1640 TYPE OF IDENTIFICATION DATA The RCC-M does not require information related to the origin of any part or weld (such as heat no., lot no., heat treatment no., welding operator no., etc.), to be marked or written on that item itself, its label, or its routing slip. n 1
26、13-2007 J 1000 / 5 RCC-M - Edition 2007 Subsection J However, marks or codes which provide clear reference to documents containing the information required for production control will always be acceptable. Where lots are divided into one or more fabrication sub-lots (e.g. for heat treatment), the or
27、iginal lot number need not appear on each item, provided that the new identification system allows for accurate identification of the items origins. J 1650 RE-MARKING AND RELABELLING If an identification code is removed or erased during fabrication, the Manufacturer shall mark or label another porti
28、on of the part as appropriate. Machined items belonging to the same lot do not need to be re-marked after each machining operation, provided that: - fabrication procedures provide for total segregation of lots, - rejects are marked immediately, visibly and indelibly. A discard shall always be identi
29、fied according to its intended use. J 1660 MARKING METHODS Marking methods shall comply with the requirements given in chapter F 2000. J 1670 REFERENCING OF WELDS J 1671 RULES APPLICABLE TO ALL EQUIPMENT a) Radiographically examined welds Each weld shall be given an alphanumeric symbol, at least on
30、the drawings and on the equipment where applicable, to establish clear correlation between the weld and its radiographs. For equipment where there is no individual marking of welds, a reference shall be marked on the part to enable the radiographs to be correctly positioned. b) Ultrasonically examin
31、ed welds Each part shall be marked individually so that the reading corresponding to the part can be identified. c) Welds subjected to liquid penetrant or magnetic particle examination These welds shall be identified so that each weld is associated with the relevant examination documents. J 1000 / 6
32、 n 113-2007 RCC-M - Edition 2007 Subsection J d) Other welds Systematic identification of other welds is not required, as the catalogue of welded joints per tank type stipulated in the requirements of Annex H1 of subsection H should allow the examination and qualification documents concerning them t
33、o be identified. J 1672 SPECIAL CASES All identification markings shall be recorded on the Manufacturers documents. If for technical reasons these markings no longer exist, their original location with relation to specified points on the equipment can be obtained from the drawing. Templates may be u
34、sed for relocating identification markings on some welded joints, specifically as an alternative to the above mentioned drawings. n 113-2007 J 1000 / 7 RCC-M - Edition 2007 Subsection J J 1000 / 8 n 113-2007 RCC-M - Edition 2007 Subsection J J 2000 MATERIALS J 2100 GENERAL For the procurement of pro
