Analysis of a full-scale integral test in PERSEO facility by using TRACE code

2017

Over the last decades a lot of experimental researches have been done to increase the reliability of passive decay heat removal systems implementing in-pool immersed heat exchanger. In this framework, a domestic research program on innovative safety systems was carried out leading the design and the development of the PERSEO facility at the SIET laboratories. The configuration of the system consists of an heat exchanger contained in a small pool which is connected both at the bottom and at the top to a large water reservoir pool. Within the frame of a national research program funded by the Italian minister of economic development, the DEIM department of the University of Palermo in coopera…

The Art of Being Ethical and Responsible : Print Media Debate on Final Disposal of Spent Nuclear Fuel in Finland and Sweden

2022

AbstractAfter decades of preparation, the final disposal of spent nuclear fuel has reached the construction stage in Finland, and the neighboring Sweden is likely to soon follow in the footsteps. These Nordic countries rely on a similar technical concept based on passive safety, advocated as a means of minimizing the burden to future generations. The scholarly literature on the ethics of nuclear waste management has thus far paid little attention to the views of the broader publics on the associated ethical challenges. This article helps to fill the gap through a longitudinal and comparative analysis of ethical discussion of the final disposal of SNF in news articles and letters to the edit…

More aware, more protected: a cross-sectional study on road safety skills predicting the use of passive safety elements among Spanish teenagers

2019

ObjectiveThis study had two objectives: first, to test the effects of sociodemographic variables, and the effects of three key road safety skills (knowledge–risk perception–attitudes) on the use of passive safety elements (PSEs) among teenagers; and second, to assess the differential impact of the study variables on PSEs use from a gender-based perspective.Setting and participantsThis cross-sectional study was framed in the paradigm of primary care, and it involved students from several educational centres in Spain. A sample of 827 Spanish teenagers (52.4% females and 47.6% males) with a mean age of M=14.41–7 (12–19) years was used.ResultsThrough SEM modelling, we found that the use of PSEs…

TRACE and RELAP5 Codes for Beyond Design Accident Condition Simulation in the SPES3 Facility

2012

Code validation on qualified experimental data is a fundamental issue in the design and safety analyses of nuclear power plants. The SPES3 facility is being built at the SIET laboratories for an integral type SMR simulation, in the frame of an R&D program on nuclear fission, funded by the Italian Ministry of Economic Development and led by ENEA. The facility, based on the IRIS reactor design, reproduces the primary, secondary and containment systems with 1:100 volume scale, full elevation and prototypical fluid and thermal-hydraulic conditions. It is suitable to test the plant response to design and beyond design accidents in order to verify the effectiveness of the primary and containm…

SAFETY CONSIDERATIONS ON TEENAGE PEDESTRIAN-BUS IMPACT

2019

This work studies the impact conditions between the adolescent pedestrian and the bus focusing on head and chest injury. The injury to the head is analyzed using both the Head Injury Criterion (HIC) 36 and the HIC15 parameters as established by the most advanced legislation and comparing the risk probability Abbreviated Injury Scale (AIS3+) and AIS4+. The parameter HIC15 gives a higher probability of risk with lower values, and therefore it can be considered more conservative. Moreover, the study of chest injury is performed with two different biomechanical parameters: the Thoracic Trauma Index (TTI) and the TTI(d); the last neglects the pedestrian mass. The results indicate that the param…
