Geologic Survey for ensuring Seismic Safety of Nuclear Power Plants

Seismic Safety Analysis and Upgrading of Operating Nuclear Power Plants

Experience of the March 11 2011, Great Tohoku earthquake clearly demonstrated that the earthquakes might be the dominating contributors to the overall risk of nuclear power plants (Institute of Nuclear Power Operations [INPO], 2011); International Atomic Energy Agency [IAEA], 2007). The seismic probabilistic safety assessments of several nuclear power plants also provided similar results. On th...

Seismic Isolation of Nuclear Power Plants

The paper presents the world state-of-the-art of the Nuclear Power Plants (NPPs) provided with seismic isolation and focuses on the main problems related to the application of this technology to so peculiar structures, characterized by high masses, large sizes and severe safety requirements due to the possibility of relevant accidents with release of radioactivity and other extremely dangerous ...

Safety in nuclear power plants in India

Safety in nuclear power plants (NPPs) in India is a very important topic and it is necessary to dissipate correct information to all the readers and the public at large. In this article, I have briefly described how the safety in our NPPs is maintained. Safety is accorded overriding priority in all the activities. NPPs in India are not only safe but are also well regulated, have proper radiolog...

Probabilistic Safety Analysis in Safety Management of Nuclear Power Plants

Applicability of Monte Carlo Method with Different Sampling Techniques for Seismic Safety Evaluation of Nuclear Power Plants

Fault-tree and Event-tree analysis is widely utilized in safety engineering and is almost exclusively relied upon in Probabilistic Safety Assessment (PSA) for nuclear power plants (NPPs). In this approach, Binary Decision Diagram (BDD), which can obtain exact solutions in theory, was introduced as an alternative for a traditional approximation method, namely Minimal Cut Set (MCS) method. Howeve...
