A risk-risk analysis-based socio-legal abstraction approach to complex decision making in nuclear systems
Complex risk-based decisions in nuclear systems are largely guided by probabilistic safety assessments and established legal precepts, such as ALARA. Typically, however, there exists a gap between the risk perceptions of experts and those of the public, which adversely affects the societal acceptability of these decisions. Often this gap is amplified by the media and campaign rhetoric, leading to ...

Risk perception in Korea: an application of psychometric paradigm
Korean students rated the risk of 70 hazards and a subset on seven risk characteristics. The results show that two higher order factors - "dread risk" and "unknown risk" - structure the Korean risk perceptions of the 70 hazards. On the dread risk dimension, all six nuclear risks (nuclear power, nuclear war/weapon, nuclear weapon tests, transportation of radioactive materials, ...

Prospects for development of technologies of radwaste geological isolation in Russia
Based on the analysis of volumes, inventory and activity of all RW accumulated in Russia, the comparative estimation on methods of their safe final isolation has been conducted. More than 90% of all RW is low level activity wastes. For such waste, the most effective method of disposal is near the surface or in a superficial (shallow) underground facility created recently or one that is already ...
