A integrated risk assessment could be developed to promote synergism between safety, security, and safeguards (3S). One of the synergies of the integrated 3S risk assessment is a 3S by Design approach for new nuclear facilities. In safety, the classical probabilistic risk assessment (PRA) has been developed to estimate the frequency of severe accident using the basic event frequency. Because of recent concern about nuclear security, a vital area identification method based on the ETs/FTs has been explored to protect vital areas of nuclear power plants against sabotage. The different difficulty in applying risk assessment to safeguards is determining the initiation of diversion of nuclear material and misuse, because the diversion of nuclear material and misuse of technology are induced by the motivation of states and intentional acts of facility operation. In this chapter, a balance among 3S risk would be explored to pursue an optimal and a cost-effective management.

The JSME Standard on the reliability evaluation of mechanical structures and related trends

Asayama, Tai

no journal, , 

In response to the increasing demands for the reliability assessment of mechanical structures, a new standard is being issued from the Japan Society of Mechanical Engineers that provides procedures applicable to mechanical products in general utilizing the Load and Resistance Factor Design (LRFD) method. This paper describes the background and technical features of the standard as well as some of the activities on developing related codes and standards.
