“…It is also worth noting that the system boundary condition of the event trees model in this work is not coupled with uncertain external environments, such as earthquakes [48], malicious reactor attacks by terrorists [49], insider worker sabotage [50] and ever-increasing cyberattacks [51], the perspectives on which future research directions could focus. Last but not least, the fault-event tree approach in this work can expand the scenarios of applications in terms of nuclear in-core instrumentations, such as the reliability analysis of robots employed for inspection and maintenance [52] of civil nuclear reactors targeting an extended lifespan.…”

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.

“…Since the “9/11” terrorist attack in America, people have become increasingly concerned that radiation sources may be utilized by terrorists [ 1 , 2 ]. Additionally, the potential risk of radiation accidents is increasing, especially in developing or politically disintegrating countries [ 3 ].…”

Dose- and time-response curves were combined to assess the potential of the comet assay in radiation biodosimetry. The neutral comet assay was used to detect DNA double-strand breaks in lymphocytes caused by γ-ray irradiation. A clear dose-response relationship with DNA double-strand breaks using the comet assay was found at different times after irradiation (p < 0.001). A time-response relationship was also found within 72 h after irradiation (p < 0.001). The curves for DNA double-strand breaks and DNA repair in vitro of human lymphocytes presented a nice model, and a smooth, three-dimensional plane model was obtained when the two curves were combined.

“…25 In the pre-9/11 era alone the International Atomic Energy Agency (IAEA) reported 175 cases of nuclear trafficking 3 . 26 Considering the amount of nuclear trafficking still persisting throughout the world it is presumable that a terrorist organization could gain the amount of material necessary to create a small-improvised device. A simple, crude, improvised nuclear fission weapon similar in design to the weapons used in Hiroshima or Nagasaki could have a yield of around 10kT.…”
