| Abstract: | To improve the reliability of the nuclear-class butterfly valve,an analysis method of fuzzy fault tree was introduced.On the basis of the basic theory and procedure of fuzzy fault tree analysis,a failure fault tree of nuclear-class valve was established,the minimum cut set was obtained,and the weak links of nuclear-class valve during its design and operation period was determined,so that the measures could be taken to improve reliability.Besides,a calculation method based on the fuzzy fault tree was propose... |
