In general, most of the safety transient cases that are typically analyzed in nuclear power plants can be performed using the point reactor kinetic equations to model the neutronic behavior of the core. This approximation usually introduces negligible errors with respect to the full three-dimensional spatial kinetics computation, and at the same time reduces both the problem complexity and the computational effort involved. Nevertheless, there exist some cases---most notably those that involve loss of coolant---where changes in the spatial distribution of power should be taken into account in order to correctly evaluate the long-term plant state. Moreover, the actuation of the second shutdown system---which in this case is based on the fast injection of a boron-based liquid absorber into the core---needs particular attention to be accurately solved and increases the difficulty of the problem. This article describes the development of a suitable computational model of the Atucha~I Nu...

This article tests the claim that anti-Muslim feelings are more widespread than general anti-foreigner feelings. It reports on two split sample experiments, in which a randomly selected part of the respondents evaluated statements for which the target group was identified as ‘foreigners’ and the other part evaluated the identical statements but with the target group identified as ‘Muslims’. By using open-ended questions we are able to separate those respondents who had Muslims in mind when asked about foreigners from those who did not. We find that anti-Muslim feelings are more intense than anti-foreigner feelings along a wide range of attitude dimensions. Furthermore, those respondents who had Muslims in mind while judging statements about foreigners, turned out to be at least as hostile as those who were asked explicitly about Muslims.

French television has broadcast health magazines since the 1950s. These magazines generally give more importance to medical expertise and curative medicine. In this article, I will present a programme that stands out from these, Sidamag, which was broadcast weekly in the mid-1990s. Targeting a young public and aiming to inform on preventive measures, Sidamag producers wanted to give space and voice to nonexperts. These three goals were only partially achieved. Preventive measures were present in all Sidamag shows however, content analysis showed that only 14% focused on prevention in youth. Furthermore, medical discourse remained dominant although significant space was given to witness testimonials.
