Propagation of Cross-Section Uncertainties in Criticality Calculations in the Framework of UAM-Phase I Using MCNPX-2.7e and SCALE-6.1

In the framework of the OECD/NEA project on Benchmark for Uncertainty Analysis in Modeling (UAM) for Design, Operation, and Safety Analysis of LWRs, several approaches and codes are being used to deal with the exercises proposed in Phase I, “Specifications and Support Data for Neutronics Cases.” At UPM, our research group treats these exercises with sensitivity calculations and the “sandwich formula” to propagate cross-section uncertainties. Two different codes are employed to calculate the sensitivity coefficients of to cross sections in criticality calculations: MCNPX-2.7e and SCALE-6.1. The former uses the Differential Operator Technique and the latter uses the Adjoint-Weighted Technique. In this paper, the main results for exercise I-2 “Lattice Physics” are presented for the criticality calculations of PWR. These criticality calculations are done for a TMI fuel assembly at four different states: HZP-Unrodded, HZP-Rodded, HFP-Unrodded, and HFP-Rodded. The results of the two different codes above are presented and compared. The comparison proves a good agreement between SCALE-6.1 and MCNPX-2.7e in uncertainty that comes from the sensitivity coefficients calculated by both codes. Differences are found when the sensitivity profiles are analysed, but they do not lead to differences in the uncertainty.

Producción BCN200 : desarrollo del proceso de obtención de la base cartográfica nacional a escala 1:200.000 : detección, edición y resolución de conflictos cartográficos en la representación a escala.

Los objetivos propios del proyecto propuesto se centran en describir las fases necesarias del proceso de producción de la Base Cartográfica Nacional a escala 1:200.000, cuyo producto final es plasmado en un mapa cartográfico concreto; Mapa Provincial con la misma escala. Todas las tareas esenciales para su elaboración se realizan de acuerdo a la finalidad principal que persigue la creación de un mapa, que es la representación clara y concisa de los elementos geográficos que definen una extensión de territorio. Se pone de manifiesto las normas y reglas específicas que son necesarias para dicha producción, atendiendo las condiciones que presenta el modelo de la base de datos concreta, compuesto por la información válida con carácter oficial, ya que debe estar registrada por las instituciones del Estado, de forma que el conjunto de información sea la más adecuada a la realidad objetiva. Se siguen aquellas pautas referentes a la captura de los datos que componen dicho modelo, teniendo en cuenta la escala cartográfica a la que se representan y ciertas condiciones geométricas. Así como aquellas normas que guían los procesos de controles de calidad y generalización de la información geográfica. También, se establecen de forma fija la serie de estilos de representación de las geometrías componen el mapa, y la simbología utilizada para identificar las entidades definidas mediante elementos puntuales. Las reglas principales descritas son las concernientes a la edición de los conflictos cartográficos producidos a la hora de representar los datos reales. La BCN200 se crea con la finalidad principal de recopilar toda la información cartográfica que define el aspecto y el conjunto de detalles, tanto geográficos y naturales, como aquellos aportados por las construcciones realizadas por el ser humano, de la superficie terrestre que abarca el territorio nacional, con la finalidad de facilitar el desarrollo de tareas semiautomáticas para obtener una producción de diversas elaboraciones cartográficas, digitales o impresas.

Electrochemical synthesis at pre-pilot scale of 1-phenylethanol by cathodic reduction of acetophenone using a solid polymer electrolyte

The pre-pilot scale synthesis of 1-phenylethanol was carried out by the cathodic hydrogenation of acetophenone in a 100 cm2 (geometric area) Polymer Electrolyte Membrane Electrochemical Reactor. The cathode was a Pd/C electrode. Hydrogen oxidation on a gas diffusion electrode was chosen as anodic reaction in order to take advantage of the hydrogen evolved during the reduction. This hydrogen oxidation provides the protons needed for the synthesis. The synthesis performed with only a solid polymer electrolyte, spe, has lower fractional conversion although a higher selectivity than that carried out using a support–electrolyte–solvent together with a spe. However, the difference between these two cases is rather small and since the work-up and purification of the final product are much easier when only a spe is used, this last process was chosen for the pre-pilot electrochemical synthesis of 1-phenylethanol.
