核电厂地质钻探岩芯的保管探讨

Discussion on Preservation of Geological Drilling Cores in Nuclear Power Plants

摘要: 为了更好地编制2013年新编能源领域行业核电标准《核电厂地质钻探岩芯保管技术规程》，制定了详细的核电厂岩芯库调研计划，走访了广州、深圳、连云港、山东荣成、大连等核电建设单位和海洋调查单位，分析了岩芯保管的现状及存在问题，研究了核电厂地质钻探岩芯保管规程的初步构架。研究表明：对于核电工程，岩芯保管至少应分为三个阶段，永久保管的岩芯应是与核安全相关的建(构)筑物地基中典型的岩石或土样标本。

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.
