Foreword

This standard is based on GB/T 1.1-2009 "Standardization Guide Part 1. Standard structure and drafting" rule drafting. This standard replaces GB 7023-1986 "solidified radioactive waste long-term leaching test." This revision compared with the previous version, the main change It reads as follows. --- Modify the standard name, the standard name was changed to "low and intermediate level radioactive waste cured standard leaching test methods"; --- Increased the preamble; --- Increasing the normative references; --- Increasing the terms and definitions; --- Complement the main technical content standards, based on the original standard leaching test methods, the recommended short-term leaching test methods. The reference to the standard ANSI/ANS-16.1-2003 (R2008) "with short-term leaching test procedures for measuring low-level radioactive waste form." The standard proposed by China National Nuclear Corporation. This standard by the National Standardization Technical Committee on Nuclear Energy (SAC/TC58) centralized. This standard was drafted. China Institute for Radiation Protection. The main drafters of this standard. Guo Xiliang, Fan Zhiwen, Liu Zhaofeng, Yangwei Bing, Feng Tao sound, Valley Cunli. This standard replaces the previous standard published case. GB/T 7023-1986. Low and intermediate level radioactive waste cured standard leaching experiment method

1 Scope
