SEAFP: passive removal of the decay heat
No full textPassive safety is a key issue for the public acceptance of fusion power. Several studies are under way in the European Safety and Environmental Assessment of Fusion Power (SEAFP) program to analyze the possible hazards and the means to keep the system safe. The demonstration that the decay heat of the structural materials of the reactor will not cause the failure of the containment, even in the absence of any form of active cooling, is a significant contribution towards the demonstration of the passive safety of fusion

Comparing Efficiency Across Markets: An Extension and Critique of the Zhang and Bartels (1998) Methodology
No full textThe use of non-parametric frontier methods for the evaluation of product market efficiency in heterogeneous markets seems to have gained some popularity recently. However, the statistical properties of these frontier estimators have been largely ignored. The main point is that nonparametric frontier estimators are biased and that the degree of bias depends on specific sample properties, most importantly sample size and number of dimensions of the model. To investigate the effect of this bias on comparing market efficiency, this contribution estimates the efficiency for several datasets for two main product categories. Following Zhang and Bartels (1998), these results comprise re-estimates for the larger samples limiting their size to that of the smaller samples when the model dimensions for different samples are identical. Furthermore, sample sizes are adjusted to mitigate the eventual differences in dimensions in specification. This allows comparing market efficiency for different markets on a more equal footing, since it reduces the bias effect to a minimum making the comparison of market efficiency possible. However, the article also points out the critical limitations of this Zhang and Bartels (1998) approach in certain respects. Apart from reporting these negative results, we also offer some suggestions for future work.Market Efficiency, Heterogeneous Product Markets, Bias, Monte-Carlo Simulation
