GB/T 13538-2017Electrical penetration assemblies in containment structures for nuclear power plants (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13538-1992 "nuclear power plant containment electrical penetrators," compared with GB/T 13538-1992, in addition to editing The main technical changes outside the sexual changes are as follows:

--- Modify the normative references (see Chapter 2,.1992 edition Chapter 2);

--- Modify some terms and definitions (see Chapter 3,.1992 edition Chapter 3);

--- Added "fiber" related content (see Chapter 4 ~ Chapter 10);

--- Increased power and control conductor rated voltage values, and adapted to the relevant national standards (see 4.2.1);

--- According to the revised equipment rated voltage, dielectric strength test frequency withstand voltage and impact withstand voltage test values were adapted Set (see 6.2.4);

--- Added "electromagnetic compatibility" of the relevant content (see 6.2.11);

--- Increased the "serious accident" related content (see 6.4);

--- Added "partial discharge (corona) test" requirements (see 7.6);

--- Added Chapter 10, contains the contents of the original Appendix A;

--- The original Appendix B to Appendix A, and the content has been modified;

--- Added Appendix B, Appendix C and Appendix D. This standard proposed by China National Nuclear Corporation. This standard by the National Nuclear Instrument Standardization Technical Committee (SAC/TC30) centralized. This standard was drafted by Shanghai Nuclear Engineering Research Institute Co., Ltd. The main drafters of this standard. Ma Tao, Wang Wen, Fang Wenzhi, Liu Gang. This standard replaces the standards previously issued as.

1 Scope

GB/T 13538-2017 is the Chinese national standard on electrical penetration assemblies in containment structures for nuclear power plants, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 December 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2018. Classification: ICS 27.120.20, CCS F69. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the design, manufacture, identification, testing, installation, and in-service monitoring of the containment of nuclear power plant containment Claim. This standard applies to nuclear power plant containment electrical penetrations design, manufacture, identification, testing, installation and in-service monitoring.
