The OECD/NEA Uncertainty Analysis in Modeling (UAM) expert group organized and launched the UAM benchmark. Its main objective is to perform uncertainty analysis in light water reactor (LWR) predictions at all modeling stages. In this paper, multigroup microscopic cross-sectional uncertainties are propagated through the DRAGON (version 4.05) lattice code in order to perform uncertainty analysis on and 2-group homogenized macroscopic cross-sections. The chosen test case corresponds to the Three Mile Island-1 (TMI-1) lattice, which is a 15 15 pressurized water reactor (PWR) fuel assembly segment with poison and at full power conditions. A statistical methodology is employed for the uncertainty assessment, where cross-sections of certain isotopes of various elements belonging to the 172-group DRAGLIB library format are considered as normal random variables. Two libraries were created for such purposes, one based on JENDL-4 data and the other one based on the recently released ENDF/B-VII.1 data. Therefore, multigroup uncertainties based on both nuclear data libraries needed to be computed for the different isotopic reactions by means of ERRORJ. The uncertainty assessment performed on and macroscopic cross-sections, that is based on JENDL-4 data, was much higher than the assessment based on ENDF/B-VII.1 data. It was found that the computed Uranium 235 fission covariance matrix based on JENDL-4 is much larger at the thermal and resonant regions than, for instance, the covariance matrix based on ENDF/B-VII.1 data. This can be the main cause of significant discrepancies between different uncertainty assessments.

In Gold Rush–era California, banking and the financial sector evolved in often distinctive ways because of the Gold Rush economy. More importantly, the abundance of gold on the West Coast provided an interesting test case for some of the critical economic arguments of the day, especially for those deriving from the descending—but still powerful—positions of the “hard money” Jacksonians.

Using the 400th anniversary of the King James Bible as a test case, this article illustrates some of the important ways in which the Bible is understood and consumed and how it has continued to survive in an age of neoliberalism and postmodernity. It is clear that instant recognition of the Bible-as-artefact, multiple repackaging and pithy biblical phrases, combined with a popular nationalism, provide distinctive strands of this understanding and survival. It is also clear that the KJV is seen as a key part of a proud English cultural heritage and tied in with traditions of democracy and tolerance, despite having next to nothing to do with either. Anything potentially problematic for Western liberal discourse (e.g. calling outsiders “dogs,” smashing babies heads against rocks, Hades-fire for the rich, killing heretics, using the Bible to convert and colonize, etc.) is effectively removed, or even encouraged to be removed, from such discussions of the KJV and the Bible in the public arena. In other words, this is a decaffeinated Bible that has been colonized by, and has adapted to, Western liberal capitalism.
