论述了秦山二期核电工程主要的自主创新内容，包括新的堆芯设计，为此进行的试验研究和计算分析，以及为新堆所作的流致振动试验、分析和堆上实测；针对二环路的安全系统的改进及相应的安全分析，以提高其安全冗余度；根据二环路的特点对核电站的参数及其配套的设备设计进行了优化，使得核电站的出力达到最大；主厂房和常规岛厂房根据二环路及厂址的特点进行了创新。自主研制了控制棒驱动机构和装卸料机，其性能超出了设计指标；采取多种方法式使大部分主设备实施国产化。在土建安装上实施了穹顶整体吊装。在调试方面实施了汽轮发电机组的非核蒸汽冲转

The self-reliance and innovation of Qinshan nuclear power project of phase II is clecilhed.It contains new reactor core design, as well as related experimental and calculation analysis, especially for new reactor design produced fluid-induced vibration model test, theoretical analysis and testing in-built reactor; aiming at two-loop NSSS a series improvement made for safety systems and related safety analysis to enhance their reliability and redundancy; according to specialty of two-loop NSSS an optimization made for NPP parameters and design of related equipments, for the purpose to make the output of NPP maximal; design of main reactor building and T-G building also improved according to characteristics of two-loop NSSS and site conditions. CRDM and refueling machine are researched and manufactured on base of self-reliance, their performance are better than design requirements, large portion of key equipments are localized through different way. In construction first time realized the integrated erection of containment dome. During the commissioning non-nuclear steam driving of T-G set, as well as 500 kV high voltage rising using emergent diesel generator, etc. are carried out. In period of operation still continuous innovation and improvement are made, in oader to keep the good record of operation.
