摘要
This article mainly describes the self-reliance and innovation of Qinshan nuclear power project of phase II,in-between 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,so that to keep the good record of operation.
