【摘要】：2011年，日本3·11大地震引發(fā)的福島第一核電站核泄漏事故給全世界核電的發(fā)展帶來(lái)深刻影響。自2011年2月，我國(guó)開始對(duì)現(xiàn)行的核電廠抗震設(shè)計(jì)規(guī)范GB60267-97進(jìn)行修訂，于2012年11月審查并通過(guò)修訂送審稿。 鑒于中國(guó)核電廠抗震設(shè)計(jì)規(guī)范(GB60267-97)2012修訂稿尚未實(shí)施，結(jié)合目前中國(guó)國(guó)內(nèi)在核電廠抗震設(shè)計(jì)及建造過(guò)程中所遵循的規(guī)范標(biāo)準(zhǔn)不一的情況，本文對(duì)國(guó)內(nèi)外不同版本的核電廠抗震設(shè)計(jì)規(guī)范進(jìn)行了比較研究。首先，對(duì)中國(guó)核電廠抗震設(shè)計(jì)規(guī)范GB50267-97與2012修訂送審稿之間的差異進(jìn)行比較，，研究修訂送審稿中的新變化是很有必要的；其次，對(duì)我國(guó)目前主要使用和借鑒的國(guó)外規(guī)范間的異同進(jìn)行比較研究，本文選取了中國(guó)、美國(guó)、法國(guó)三國(guó)核電廠抗震設(shè)計(jì)規(guī)范，這將有助于擴(kuò)大國(guó)內(nèi)規(guī)范的兼容性，吸收國(guó)外抗震設(shè)計(jì)的優(yōu)點(diǎn)；第三，本文以某代核電廠安全殼屏蔽廠房PCS重力排水水箱的抗震設(shè)計(jì)為例，按照不同核電廠抗震設(shè)計(jì)規(guī)范要求對(duì)其抗震性能進(jìn)行了分析。本文對(duì)不同規(guī)范的比較研究目的是，發(fā)現(xiàn)不同規(guī)范之間的共性與差異，并將這些差異與我國(guó)核電抗震設(shè)計(jì)的實(shí)際相結(jié)合進(jìn)行說(shuō)明，希望通過(guò)本文的研究工作，可以為我國(guó)核電廠抗震設(shè)計(jì)規(guī)范的修訂提供可行的建議。 論文主要完成了以下工作： (1)本文首先對(duì)中國(guó)核電廠抗震設(shè)計(jì)規(guī)范GB50267-97與2012修訂送審稿進(jìn)行了全面的比較。主要在核電廠抗震設(shè)計(jì)適用范圍、抗震設(shè)防目標(biāo)、抗震物項(xiàng)分類和設(shè)防水準(zhǔn)、核電廠的概念設(shè)計(jì)、抗震設(shè)計(jì)計(jì)算模型、地震作用計(jì)算方法、抗震設(shè)計(jì)反應(yīng)譜等方面，對(duì)差異性進(jìn)行了研究，這幾個(gè)方面也是兩版規(guī)范條文之間差異較大的部分。2012修訂送審稿既吸納了近年來(lái)抗震設(shè)計(jì)的先進(jìn)理論和實(shí)踐，又延續(xù)了原規(guī)范的設(shè)計(jì)思路，符合我國(guó)核電事業(yè)的發(fā)展。 (2)對(duì)中國(guó)、美國(guó)、法國(guó)三國(guó)相關(guān)核電廠抗震設(shè)計(jì)規(guī)范內(nèi)容進(jìn)行了比較。比較方法與國(guó)內(nèi)規(guī)范間的比較相似。通過(guò)比較發(fā)現(xiàn)三國(guó)規(guī)范在抗震設(shè)計(jì)基本思路具有共性，但在規(guī)范條文某些細(xì)節(jié)要求又有差異，既結(jié)合了本國(guó)核電技術(shù)的特點(diǎn)，又符合目前國(guó)際核電規(guī)范的設(shè)計(jì)準(zhǔn)則。 (3)對(duì)某代核電廠安全殼屏蔽廠房PCS重力排水水箱的抗震設(shè)計(jì)進(jìn)行了初步的研究。在研究過(guò)程中，運(yùn)用耦合歐拉—拉格朗日技術(shù)CEL對(duì)PCS重力排水水箱的流固耦合作用進(jìn)行了數(shù)值模擬，研究了地震作用下由于液體晃動(dòng)對(duì)安全殼屏蔽廠房抗震性能的影響，并與核電廠抗震設(shè)計(jì)規(guī)范對(duì)貯液容器抗震設(shè)計(jì)的規(guī)范要求進(jìn)行了比較。
[Abstract]:In 2011, the Fukushima Daiichi nuclear accident triggered by Japan's 3.11 earthquake had a profound impact on the development of nuclear power around the world.Since February 2011, the current code for seismic design of nuclear power plants (GB60267-97) has been revised in China.In view of the fact that the revised GB60267-97 / 2012 code for seismic design of nuclear power plants in China has not yet been implemented, and in the light of the fact that there are different standards for the seismic design and construction of nuclear power plants in China at present,In this paper, different versions of codes for seismic design of nuclear power plants at home and abroad are compared and studied.Firstly, by comparing the differences between GB50267-97 and 2012 revised draft for seismic design of Chinese nuclear power plants, it is necessary to study the new changes in the revised draft.Comparing and studying the similarities and differences among the foreign codes which are mainly used and used for reference in our country, this paper selects the seismic design codes of nuclear power plants in China, the United States and France, which will help to expand the compatibility of domestic codes.The advantages of seismic design in foreign countries are absorbed. Thirdly, the seismic performance of PCS gravity drainage tank of a kind of nuclear power plant containment shielding plant is analyzed according to the requirements of different codes for seismic design of nuclear power plants.The purpose of this paper is to find out the commonness and difference between different codes, and to combine these differences with the practice of seismic design of nuclear power in China.It can provide feasible suggestions for the revision of the code for seismic design of nuclear power plants in China.The main work of the thesis is as follows:In this paper, a comprehensive comparison between GB50267-97 and 2012 revised draft for seismic design of nuclear power plants is made.Mainly in the application scope of seismic design of nuclear power plant, seismic fortification target, classification and level of seismic items, concept design of nuclear power plant, seismic design calculation model, seismic action calculation method, seismic design response spectrum, etc.The differences have been studied. These aspects are also the parts of great difference between the two versions of the code. The revised draft of 2012 not only absorbs the advanced theory and practice of seismic design in recent years, but also continues the design ideas of the original code.In line with the development of nuclear power industry in China.The contents of the code for seismic design of nuclear power plants in China, the United States and France are compared.The comparison method is similar to the comparison between domestic norms.Through comparison, it is found that the basic ideas of seismic design of the codes of the three countries are common, but there are differences in some details of the specifications, which not only combines the characteristics of nuclear power technology in our country, but also accords with the design standards of the current international nuclear power codes.The seismic design of PCS gravity drainage tank in containment shielding plant of a nuclear power plant is studied preliminarily.In the course of the study, the coupled Euler-Lagrangian technique (CEL) is used to simulate the fluid-solid coupling effect of the PCS gravity drainage tank, and the effect of liquid sloshing on the seismic behavior of the containment shielded powerhouse under earthquake is studied.The requirements for seismic design of liquid storage vessels are compared with the code for seismic design of nuclear power plants.
