The 1984 Windscale study raised concern about a possible association between living in the vicinity of nuclear power plants and childhood cancer. No such effect for all cancers was seen in ecological studies in Germany (1980-1995). Results from exploratory analyses led to a new study. Pre-selected areas around all 16 major nuclear power plants in Germany formed the study area. The design is a m...

Currently, there is a trend in nuclear power plants (NPPs) toward introducing digital and computer technologies into main control rooms (MCRs). Safe generation of electric power in NPPs requires reliable performance of cognitive tasks such as fault detection, diagnosis, and response planning. The digitalization of MCRs has dramatically changed the whole operating environment, and the ways opera...

In order to study the transfer of water borne 1 J , Cs and *°Sr into rice plants, pot experiments were done by growing rice plants on soils taken from rice beds near two nuclear power plants: Qinshan Nuclear Power Plant and Daya Bay Nuclear Power Plant in China. The vertical migration of '"Cs and ''Sr in the soil samples due to leaching was studied, and results show that almost all the contamin...

Safety of the personnel of a nuclear power plant (NPP) and the environment around the plant should be ensured against all natural hazards including earthquakes. With public safety as the paramount concern, NPP facilities are designed to withstand low-probability, high-magnitude earthquakes. In this paper, details are discussed regarding the evolution of seismic analysis and design aspects of nu...

How does the American public assess risk when it comes to national security issues? This paper addresses this question by analyzing variation in citizen probability assessments of the terrorism risk of nuclear power plants. Drawing on the literature on how motivated reasoning, selective information processing, and domain-specific knowledge influence public opinion, we argue that heterogeneous i...

This paper describes a new technology for analyzing alarm cascades in nuclear power plant control rooms in real-time, thereby making operation safer and more productive. The technology is based on multilevel flow models and a root cause analysis algorithm developed at Lund University and GoalArt. It enables the solution of the alarm cascade problem for full-scale nuclear power plants. In the ne...

The Fukushima Daï-ichi nuclear power plant (FDNPP) accident resulted in radioactive Cs being discharged into the local marine environment. While Cs bioaccumulates in biota and slowly depurates, the Cs concentrated in biota constitutes a source of Cs for animals feeding on each other. The marine biota therefore serves as a pool that recycles Cs, and this recycling process delays depuration in th...

The Great East Japan Earthquake hit Fukushima Prefecture on March 11, 2011, just over 3 years ago and it continues to affect our lives. In Fukushima, many people are confirmed dead or still missing due to the earthquake and/or tsunami. Additional "disaster-related deaths" have been attributed to the Fukushima Daiichi Nuclear Power Plant (NPP) accident. Mortality among the institutionalized elde...

Nuclear power plants (NPPs) have recently undergone rapid development in China. To improve the performance of both NPPs and grids during adverse conditions, a precise understanding of the coordination between NPPs and grids is required. Therefore, a new mathematical model with reasonable accuracy and reduced computational complexity is developed. This model is applicable to the short, mid, and ...
