1 Scope

GB/T 17680.3-2025 is the Chinese national standard on criteria for emergency preparedness and response for nuclear power plants - part 3: functional and physical characteristics of off-site emergency facilities, 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 5 October 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 5 October 2025. Classification: ICS 27.120, CCS F 77. 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 document specifies the general requirements, functional positioning, characteristic requirements, system and equipment configuration of off-site emergency facilities for nuclear power plants. This document applies to off-site emergency response facilities for nuclear accidents in the province (autonomous region, or municipality) where the nuclear power plant is located. Other nuclear facilities requiring off-site emergency response... Implement with reference to this.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 emergency facilities Emergency response sites, systems, and equipment are set up in accordance with the principle of positive compatibility and relevant regulations.

3.2 In the event of an emergency at a nuclear power plant, information is transmitted using communication methods. Note

1.Emergency communication is a fundamental means of organizing and commanding nuclear accident response. Note

2.Emergency communications must be rapid, accurate, and uninterrupted, and confidentiality must be maintained when necessary.

3.3 Monitoring conducted in the event of an emergency at a nuclear power plant to determine the level of radioactive contamination and radiation in the environment.

4 General Requirements

4.1 Meet nuclear emergency response requirements Off-site emergency facilities should meet the needs of nuclear emergency response, be coordinated with off-site nuclear emergency arrangements, and facilitate the implementation of nuclear emergency response actions.
