Desenvolupament i validació d'una metodologia per a l'avaluació de la cultura de seguretat per mitjà de l'observació de reunions de treball en una ce…
2010
L'objectiu d'aquest treball és descriure el desenvolupament i la validació d'una metodologia per a avaluar la cultura de seguretat per mitjà de l'observació de reunions de treball. Es va partir de la definició de cultura de seguretat més estesa dins el sector (International Atomic Energy Agency, 1991), les cinc dimensions que presenta i els atributs corresponents. La validesa d'aquesta metodologia es posà a prova en una central nuclear mitjançant l'observació d'un total de 36 reunions de treball de naturalesa molt diversa. Els resultats indiquen que l'observació de les reunions és un mètode útil per a l'avaluació de la cultura de seguretat. Comparada amb els mètodes tradicionals per a fer a…
Risk communication and risk perception : the case of nuclear power public debate in Lithuania
2012
The purpose of the present study is to investigate the risk communication of organizations and risk understanding, or risk perception, of the public at large. The theoretical analysis generates the methodological model of risk communication and risk perception. This framework provides the ground for the empirical study focusing on nuclear power debate in Lithuania with the purpose of investigating the overall risk communication of Lithuanian organizations in relation to nuclear power issues, as well as citizens’ perceptions about the technology. The empirical investigation is based on a content analysis of qualitative data concerning risk communication of the target organizations, as well a…
Attività di interconfronto tra codici di trasporto atmosferico per la preparazione e la risposta alle emergenze nucleari
2019
In questo lavoro vengono presentati e confrontati i risultati ottenuti con tre differenti codici (FLEXPART, CALPUFF e ldX) per il trasporto atmosferico di inquinanti radioattivi. I codici vengono confrontati su una singola simulazione di un possibile rilascio incidentale alla stazione frontaliera di Gösgen (CH), in condizioni meteorologiche sfavorevoli per il territorio italiano. In this work we present and compare the results obtained iwth three different codes (FLEXPART, CALPUFF and ldX) for the atmospheric dispersion of radioactive pollutants. The codes are compared on a single simulation of a possible incident release in the Gösgen (CH) nuclear power plant with weather conditions that a…
Atmospheric dry deposition processes of particles on urban and suburban surfaces: Modelling and validation works
2019
Abstract Dry deposition process is one of the important pathways for the removal of particles from atmosphere. It is the result of a combination of different environmental and physical factors as atmospheric conditions, particle properties, characteristics of the canopy. For this latter factor, urban canopy represents unevenly combinations of different types of surface elements that increases the complexity of deposition process phenomena. Therefore, particle dry deposition on urban surfaces is not easy to configure and, although empirical or semi-empirical models in literature have been developed to address this aspect, there is not standardized and commonly accepted criteria, especially f…
