Discussion on Preservation of Geological Drilling Cores in Nuclear Power Plants
-
Abstract
For the better compilation of new nuclear standard of technical code for geological drilling core preservation of nuclear power plants in 2013, the investigation plan is detailly drawn up for drilling cores library of nuclear power plants construction companies and marine investigation institutes in Guangzhou, Shenzhen, Lianyungang, Rongcheng and Dalian in China. The current situation and problems of core preservation are analyzed, and the important materials and contents for preliminarily building the framework of the standard are studied. The research shows that geological core preservation should be divided into at least three phases for nuclear power engineering. Permanent-preservation cores should be typical rock or soil specimens of nuclear safety-related building (structure) foundations.
