Climate change affects technical systems, structures and infrastructures, changing the environmental context for which systems, structures and infrastructure were originally designed. In order to prevent any risk growth beyond acceptable levels, the climate change effects must be accounted for into risk assessment models. Climate models can provide future climate data, such as air temperature and pressure. However, the reliability of climate models is a major concern due to the uncertainty in the temperature and pressure future projections. In this work, we consider five climate change models (individually unable to accurately provide historical recorded temperatures and, thus, also future projections) and ensemble their projections for integration in a probabilistic safety assessment, conditional on climate projections. As case study, we consider the passive containment cooling system of two AP1000 nuclear power plants. Results provided by the different ensembles are compared. Finally, a risk-based classification approach is performed to identify critical future temperatures, which may lead to passive containment cooling system risks beyond acceptable levels.

The Impact

Based on analysis of F.D. Mordukhai-Boltovskoy’s publications, this paper examines the history of studies of the impact of thermal and nuclear power plants, which were originally performed under the classical “Haeckelian” ecological paradigm: the external effect of technogenic factors on aquatic ecosystems and biota. The decline in interest in the problem was not associated with a decrease in the technogenic impact or changes in the energy industry. However, the paradigm itself is changing in association with the emergence of the concept of a technoecosystem. The cooling ponds of thermal power plants (TPPs) and nuclear power plants (NPPs) can be used as models of climate change, particularly climate warming. The materials obtained in studies of the effects of technogenic temperature rise are still underused by hydrobiologists studying climate change and its potential consequences.

The Impact

Abstract With the development of the nuclear energy industry and the increasing demand for environmental protection, the impact of nuclear power plant radiation on the environment has gradually entered the public view. This article combs the nuclear power plant radiation environmental management systems of several countries, takes the domestic and foreign management of radioactive effluent discharge from nuclear power plants as a starting point, analyses and compares the laws and standards related to radioactive effluents from nuclear power plants in France, the United States, China, and South Korea. In this paper, the management improvement of radioactive effluent discharge system of Chinese nuclear power plants has been discussed.
