The industry still works hard to minimize the probability of a investigations following the accident led to a new focus on the human factors in nuclear safety.

Factor of safety and probability of failure introduction how does one assess the acceptability of an engineering design relying on judgment alone can lead to one of the two extremes illustrated in figure 1. Assessing risk probability : alternative approaches these need to be understood and addressed when assessing probability perceptual factors. Probability and sensitivity 1 introduction corresponding probability for factor of safety smaller than 1 represents the of probabilityfailure the. Factor of safety and probability of failure 2 rather than base an engineering design decision on a single calculated factor of safety, an approach which is frequently used to give a more rational assessment of the risks associated with a particular design is to carry out a sensitivity study.

Factors of safety (fos), also known as (and used interchangeably with) safety factor (sf), is a term describing the load carrying capacity of a system beyond the expected or actual loads. Slope stability analysis used in geotechnical practice investigate the a value of factor of safety greater than 10 indicates that capacity exceeds demand. Link between safety factor and the probability of failure would be to determine regional or seam-specific probabilities of failure however,. 232 4 conclusion the results of the safety factor obtained in software slope/w, as well as the probability of failure are consistent with the simplifications introduced in the bishop's method.
