Foreword

This code has been prepared by the Electric Power Planning and Design General Institute in collaboration with associated organizations as required by the Notice on Development and Revision Plan of National Standards for Engineering Construction in 2006 issued by the former Ministry of Construction（JB〔2006〕136）.

In the preparation of this code，thedrafting panel investigated，summarized and adopted the latest research results in the seismic engineering field with respect to the engineering practical experience in seismic and experience and lessons from major earthquakes in nuclear power plants at home and overseas.Before the draft was reviewed and finalized，the task team iteratively revised the key contents based on wide consultations.

This code is organized into 7 chapters and 4 appendices，mainly including general provisions，terms and symbols，basic requirements，preliminary feasibility study，feasibility study，preliminary siting，and content and format of the study report.

This code is administered by the Ministry of Housing and Urban-Rural Development，with the Standardization Center of the China Electricity Council in charge of its routine management and the Electric Power Planning and Design General Institute in charge of the interpretation of specific technical contents.During the implementation of this code，the interests concerned are expected to seriously summarize the experiences and collect the relevant information based on the project practices and at any time refer any comments and suggestions to Electric Power Planning and Design General Institute at the address:No.65，Ande Road，Xicheng District，Beijing，Postcode:100120，for reference in the future revision of this code.
