Optimization of design solutions of protective structures of erections of nuclear power stations

Abstract

The ideas of optimization of constructive solutions of protective erections of nuclear power stations are presented. A problem of such optimization for the securing of nuclear and radiation safety for different regime of nuclear power stations exploitation, including extreme action, is very topical at present time. Modern home and international achievements on the considered subjects are demonstrated and modern demands, analysis methods, and problems of design of erections of nuclear power stations that give an opportunity to assure their safety exploitation under collision of flying objects are given as well. The results confirm wide opportunities of improvement of the constructive solutions of protective shells of reactor sections of nuclear power stations with the application of innovative materials that give the prospects to economize the material resources considerably and to raise the reliability and safety of exploitation of erections of nuclear power stations simultaneously.
