“…Since the nuclear renaissance [3] and the subsequent increase in nuclear newbuild projects [4] globally, new needs for safety assessment [5,6] of the complex nuclear power system has arisen. Securing a very high level of design and operating safety with reduced costs will not only be technically required for the burgeoning nuclear sector, but also from the policy [7] point of view to approach the challenge in addressing the public's negative perception [8] on nuclear power in the post-Fukushima era [9]. Since introducing revolutionary reactor technologies takes a long time, traditional light water reactors (LWR) will inevitably remain the dominant technology for many decades in the foreseeable future.…”

A systematic probabilistic safety assessment for a boiling water nuclear reactor core is performed using fault trees and event trees analysis models. Based on a survey of the BWR’s safety systems against potential hazards, eight independent failure modes (initiating events) triggered scenarios are modelled and evaluated in the assembled fault-event trees, obtaining the two key outcome probabilities of interest, i.e., complete core meltdown (CCMD) frequency and minor core damage (MCD) frequency. The analysis results indicate that the complete loss of heat sink accounts for the initiating accident most vulnerable to CCMD (with a frequency of 1.8 × 10 − 5 per year), while the large break in the reactor pressure vessel is the least susceptible one (with a frequency of 2.9 × 10 − 12 per year). The quantitative risk assessment and independent review conducted in this case study contributed a reference reliability model for defense-in-depth core optimizations with reduced costs, informing risk-based policy decision making, licensing, and public understanding in nuclear safety systems.

“…Individuals' perceptions of objective issues inevitably affect their attitudes and behaviors toward objective issues. When an accident occurs, such as the Fukushima nuclear power accident 3 , 4 , the air pollution incident 5 , etc., risk perception is often incorporated into the management decision-making process. On the one hand, research on risk perception, which focuses on the changes in people's perception of risk before and after the accident, can promote risk communication and provide decision-making basis for risk management.…”

New observation of perceptive mechanism behind the long-lasting change of people's community mobility: evidence from COVID-19 in China

COVID-19 pandemic provides an opportunity to investigate how a new and long-lasting threat affects public risk perception and social distancing behavior, which is important for pandemic risk management and recovery of the tertiary industry. We have found that the mechanism that perception decides behavior changes over time. At the beginning of the pandemic, risk directly shapes people’s willingness of going out. But under a persistent threat, perception no longer plays the direct role of shape people’s willingness. Instead, perception indirectly influences the willingness by shaping people’s judgment about the necessity of traveling. Switching from direct to indirect influence, perception’s effect is enlarged, which partially prevents people from returning to normal life even if the governmental ban is removed in a zero-COVID community.

“…Irrespective of the nature of a nuclear accident/incident anywhere in the world, perception of risk is being affected and reinforced continuously. Scholars (Nishikawa, Kato, Homma, & Takahara, 2016;Visschers & Siegrist, 2013) argue that people expressed a gloomier attitude toward nuclear technology after the Fukushima nuclear accident than before. A nationwide survey in Australia during the pre-Fukushima era highlighted that people were willing to accept nuclear energy to counter the threat posed by climate change.…”

An exploration of public risk perception and governmental engagement of nuclear energy in India

Public acceptance constitutes an important factor in successfully establishing and operating nuclear power plants. This paper explores public attitudes to the Kudankulam Nuclear Power Project commissioned in 2013 and situated in Southern India, through assessing the role of socio‐demographic factors, externalities, and social trust in determining the level of public acceptance. An exploratory survey (n = 100) was carried out in two administrative units in the vicinity of the plant. The study reveals that acceptance of the plant is positively correlated with positive externalities and trust in governmental entities, whereas negative externalities and trust in antinuclear nongovernmental organizations and media are associated with negative public perception. The results show that governmental policies on nuclear power must support the effects of positive externalities and reduce the effects of negative externalities.
