GB/T 17680.1-2008Criteria for emergency planning and preparedness for nuclear power plants - Part 1: The dividing of emergency planning zone (English PDF)

Foreword

GB/T 17680 Criteria for emergency planning and preparedness for nuclear power plants is divided into 12 parts. - Part 1. The dividing of emergency planning zone; - Part 2. Offsite emergency functions and organizations; - Part 3. Functional and physical characteristics of the offsite emergency facilities; - Part 4. The offsite emergency planning and implementing procedures; - Part 5. Maintenance of offsite emergency response capabilities; - Part 6. On-site emergency response functions and organizations; - Part 7. Function and physical characteristics of on-site emergency facilities; - Part 8. On-site emergency planning and implementing procedures; - Part 9. Maintenance of on-site emergency response capacity; - Part 10. Criteria for emergency radiological field monitoring, sampling and analysis conducted by nuclear power plant operating organizations; - Part 11. Criteria for the conduct of offsite radiological assessment for emergency response; - Part 12. Planning, development, conduct and evaluation of nuclear emergency drills and exercises. This Part is part 1 of GB/T 17680. This Part adopts internationally-used general safety codes for confirming the emergency planning zone of the nuclear power plant, and references to the division codes of emergency planning zone of the nuclear power plant in America, Canada, France, England, etc. This Part replaces GB/T 17680.1-1999 Criteria for emergency planning and preparedness for nuclear power plants - The dividing of emergency planning zone. This revision is mainly for some editing modification. The main differences between GB/T 17680.1-1999 and this Part are as follows: - The contents of the forward are more comprehensive; clarify that this Part provides the technical basis for the emergency planning zone of nuclear power plant. - The reference document is revised to be the national standard GB 18871 that is formally issued and executed by our country. - The regulations in previous clause 4.4.4 "considering the release of radioactive substance to the atmosphere, optionally considering the release of radioactive substance to the water when confirming the scope of the emergency planning zone" are deleted. - In 6.1.1, the regulations for considering the heat power of unit reactor are considered when confirming the scope of plume emergency planning zone. This Part was proposed by China National Nuclear Corporation. This Part shall be under the jurisdiction of National Nuclear Energy Standardization Technology Committee. The drafting organizations of this Part. Nuclear Industry Standardization Institute, Guangdong Nuclear Power Joint Venture Company, and Safety & Quality Department of China National Nuclear Corporation. Main drafter of this standard. Zhuo Fengguan. The previous version replaced by this standard is as follows: - GB/T 17680.1-1999. Criteria for Emergency Planning and Preparedness for Nuclear Power Plants - Part 1. The Dividing of Emergency Planning Zone

1 Scope

GB/T 17680.1-2008 is the Chinese national standard on criteria for emergency planning and preparedness for nuclear power plants - part 1: the dividing of emergency planning zone, 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 2 July 2008 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 April 2009. Classification: ICS 27.120.20, CCS F77. 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 Part of GB/T 17680 specifies the general division codes of emergency planning zone of nuclear power plant; it recommends the scope of the emergency planning zone of pressurized water reactor nuclear power plant. This Part is suitable for dividing the emergency planning zone of pressurized water reactor nuclear power plant; the division of the emergency planning zone of other types of reactor nuclear power plant can refer to this Part.

3 Terms and definitions For the purpose of this Part of GB/T 17680, the following terms and definitions apply.

3.1 Emergency planning zone A zone that is established around the nuclear power plant in advance, within which the emergency plan has been prepared and emergency preparation has been made, in order to timely and effectively adopt protective action to protect the public when the nuclear power plant has an accident.

3.2 Plume emergency planning zone An emergency plan zone that is established in accordance with exposure pathways of plume (external exposure of plume immersion, internal exposure of ingestion, and the following rule. Out of the scope of ingestion emergency planning zone, the pollution level of food and drinking water that are caused by majority of serve accident series shall not exceed the general action level of food and drinking water as regulated in GB 18871.
