Abstract (sommario):

Abstract During the in-vessel stage of a severe accident in a CANDU 6 reactor, decay heat from a collapsed core would be rejected through the calandria walls into the surrounding water. At the step in the calandria wall, the subshell and annular plate meet at a right angle pointing into the calandria. The geometry at this joint could concentrate the exiting heat flux, potentially leading to calandria failure. Finite element analysis is used to study the heat transfer near the welded joint. Different weld profiles, boundary conditions, and decay heat characteristics are considered, and the local concentration of exiting heat flux is calculated.

Abstract (sommario):

In 2009 May, the National Research Universal (NRU) calandria leaked. During the next year, the calandria was inspected with six new Non-Destructive Evaluation (NDE) techniques to determine the extent of the corrosion, repaired, and finally the repair was inspected with four additional new NDE techniques before the reactor was returned to service. The calandria is surrounded by a light-water reflector vessel fabricated from the same material as the calandria vessel. Concerns that the same corrosion mechanism had damaged the reflector vessel led to the development of a system to inspect the full circumference of the reflector wall for corrosion damage. The inspection region could only be accessed through 64 mm diameter ports, was 10 m below the port, and had to be inspected from the corroded surface. The ultrasonic technique was designed to produce a closely spaced wall thickness (WT) grid over an area of approximately 5 m2 on the corroded surface using a very small probe holder. This paper describes the Reflector Wall Inspection (RWI) development project and the system that resulted.

Abstract (sommario):

This paper illustrates the application of a severe accident analysis computer program to the uncertainty analysis of molten corium-concrete interaction (MCCI) phenomena in cases of severe accidents in CANDU6 type plant. The potential hazard of MCCI is a failure of the reactor building owing to the possibility of a calandria vault floor melt-through even though the containment filtered vent system is operated. Meanwhile, the MCCI still has large uncertainties in several phenomena such as a melt spreading area and the extent of water ingression into a continuous debris layer. The purpose of this study is to evaluate the MCCI in the calandria vault floor via an uncertainty analysis using the ISAAC program for the CANDU6.

El presente trabajo de investigaciÃ³n fue llevada a cabo con el objetivo de determinar el comportamiento de los campos de velocidades, temperaturas y presiones del jugo de caÃ±a, como fluido de estudio, de un sistema de dos-fase de un evaporador Roberts. Para simular computacionalmente el movimiento de la partÃcula del fluido en un medio ambiente de dos-fases se usÃ³ el cÃ³digo CFX-ANSYS, el cual calcula el campo del flujo por el MÃ©todo del Volumen Finito. Asimismo, seÂ registraron las condiciones del flujo tanto de jugo como de vapor a la entrada y salida de un evaporador Roberts de 785 m2 Â de Industrial PucalÃ¡ en Chiclayo. Para validar el perfil del campo de temperatura simulados computacionalmente se tomaron datos experimentales del jugo hirviendo, colocando bulbos de temperatura sobre la calandria del evaporador. Resultados obtenidos de la simulaciÃ³n computacional de los campos de velocidad, temperatura y presiÃ³n del jugo de caÃ±a de un evaporador Roberts mostraron que la velocidad del jugo cae dramÃ¡ticamente en el fondo y calandria del evaporador. RecirculaciÃ³n de jugo abundante ocurreÂ entre la lÃnea de salida de jugo evaporado y el tubo central de recirculado. AsÃ mismo,Â las temperaturas del fluido que hierve son mÃ¡s altas en la parte media de la altura de la calandria, y suÂ presiÃ³n decrece uniformemente desde el fondo al cuerpo del evaporador. Los valores de la temperatura del jugo simulados computacionalmente y medidos experimentalmente mostraron estar en buena concordancia, validando al modelo desarrollado.

Abstract (sommario):

Abstract: Evolutionary biologists often assume that male competition for females is the root of the evolution of elaborate coloration and song. However, recent findings show that in the ancestral history of songbirds, it is likely that song occurred in both males and females. Surprisingly, no data exist on female song for many species of birds. We investigated whether the Puerto Rican Oriole (Icterus portoricensis), a tropical songbird, exhibits both male and female song. For this project we marked individuals with sex-specific color bands and confirmed sex using genetic sexing. We repeatedly recorded both male and female orioles singing. Furthermore, female Puerto Rican Oriole song appears to be similar to male song, with no obvious differences in structure. Our study provides further evidence of the ubiquity of female song in tropical songbirds. Finally, our findings provide support that female song is ancestral in the Caribbean oriole clade, and that song dimorphism in temperate breeding species is a result of a loss of female song. Keywords: female song, female vocalizations, Icterus portoricensis, Puerto Rican Oriole, tropical songbirds Resumen: Biólogos evolutivos a menudo asumen que la competencia masculina para las mujeres es la raíz de la evolución de la coloración y canción. Sin embargo, recientes hallazgos muestran que los machos y las hembras ancestrales de todos los pájaros cantores probablemente cantaban; pero existen pocos datos sobre el canto de las hembras de muchas especies de aves. Nosotros investigamos el actuada canta de los hembras y los machos el pájaro, la Calandria Puertorriqueña (Icterus portoricensis). Para este proyecto, marcamos individuos de diferentes sexos con bandas de color específicas y confirmamos el sexo usando métodos genéticos. Adicionalmente; grabamos las canciones de ambos sexos de las Calandrias Puertorriqueñas. Somos los primeros en documentar canción de ambos sexos en esta especie. Por otra parte, la canción de la Calandria Puertorriqueña aparece ser similar a la canción de los machos, sin diferencias evidentes en la estructura de la canción. Nuestro estudio ofrece evidencia adicional de la omnipresencia de la canción femenina en las aves canoras tropicales. Por último, nuestros resultados respaldan la idea de que la canción femenina es ancestral en la clade de las calandrias caribes, y que el dimorfismo en la canción de especies de aves templadas es un resultado de la pérdida de la canción femenina. Palabras clave: aves canoras tropicales, Calandria Puertorriqueña, canto de hembras, Icterus portoricensis, vocalizaciones de hembras Résumé: Les biologistes évolutionnistes supposent souvent que la compétition entre mâles pour les femelles est à l’origine de l'évolution vers une coloration et un chant élaborés. Toutefois, des résultats récents montrent que, dans l'histoire ancestrale des oiseaux chanteurs, il est probable que le chant ait été présent à la fois par chez les mâles et chez les femelles. Étonnamment, aucune donnée n'existe sur le chant des femelles pour de nombreuses espèces d'oiseaux. Nous avons étudié si l'Oriole de Porto Rico (Icterus portoricensis), un oiseau chanteur tropical, présentait à la fois un chant mâle et un chant femelle. Pour ce projet, nous avons marqué les individus avec des bagues de couleurs différentes selon le sexe et confirmé le sexe par des analyses génétiques. Nous avons enregistré à plusieurs reprises des mâles et des femelles en train de chanter. En outre, le chant des femelles d't semble être similaire à celui des mâles, sans différence évidente dans la structure. Notre étude fournit une preuve supplémentaire de l'omniprésence du chant des femelles chez les oiseaux chanteurs tropicaux. Enfin, nos résultats soutiennent l'hypothèse affirmant que le chant des femelles est ancestral dans le clade des orioles des Caraïbes, et que le dimorphisme du chant chez les espèces nichant dans les régions tempérées est le résultat d'une disparition de chant chez les femelles. Mots clés: chant des femelles, Icterus portoricensis, oiseaux chanteurs tropicaux, Oriole de Porto Rico, vocalisation des femelles

Abstract (sommario):

Three-dimensional moderator flow in the calandria tank of CANDU-6 pressurized heavy water reactor (PHWR) is computed with Open Field Operation and Manipulation (OpenFOAM), an open-source computational fluid dynamics (CFD) code. In this study, numerical analysis is performed on the real geometry model including 380 fuel rods in the calandria tank with the heat-source distribution to remove uncertainty of the previous analysis models simplified by the porous media approach. Realizable k-ε turbulence model is applied, and the buoyancy due to temperature variation is considered by Boussinesq approximation for the incompressible single-phase Navier-Stokes equations. The calculation results show that the flow is highly unsteady in the moderator. The computational flow visualization shows a circulation of flow driven by buoyancy and asymmetric oscillation at the pseudo-steady state. There is no region where the local temperature rises continuously due to slow circulating flow and its convection heat transfer.

Abstract (sommario):

During an unmitigated severe accident in a pressurized heavy water reactor (PHWR) with horizontal fuel channels, the core may disassemble and relocate to the bottom of the calandria vessel. The resulting heterogeneous in-vessel terminal debris bed (TDB) would likely be quenched by any remaining moderator, and some of the decay heat would be conducted through the calandria vessel shell to the surrounding reactor vault or shield tank water. As the moderator boiled off, the solid debris bed would transform into a more homogeneous molten corium pool located between top and bottom crusts. Until recently, the severe accident code MAAP-CANDU assumed that unreleased volatile and semi-volatile fission products remained in the TDB until after calandria vessel failure, due to low diffusivity through the top crust and the lack of gases or steam to flush released fission products from the debris. However, national and international experimental results indicate this assumption is unlikely; instead, high- and medium-volatility fission products would be released from a molten debris pool, and their volatility and transport should be taken into account in TDB modelling. The resulting change in the distribution of fission products within the reactor and containment, and the associated decay heat, can have significant effects upon the progression of the accident and fission-product releases to the environment. This article describes a postulated PHWR severe accident progression to generate a TDB and the effects of fission-product releases from the terminal debris, using the simple release model in the MAAP-CANDU severe accident code. It also provides insights from various experimental programs related to fission-product releases from core debris, and their applicability to the MAAP-CANDU TDB model.

Abstract (sommario):

We measured carbon stocks at two forest reserves in the cloud forest region of Monteverde, comparing cleared land, experimental secondary forest plots, and mature forest at each location to assess the effectiveness of reforestation in sequestering biomass and soil carbon. The biomass carbon stock measured in the mature forest at the Monteverde Institute is similar to other measurements of mature tropical montane forest biomass carbon in Costa Rica. Local historical records and the distribution of large trees suggest a mature forest age of greater than 80 years. The forest at La Calandria lacks historical documentation, and dendrochronological dating is not applicable. However, based on the differences in tree size, above-ground biomass carbon, and soil carbon between the Monteverde Institute and La Calandria sites, we estimate an age difference of at least 30 years of the mature forests. Experimental secondary forest plots at both sites have accumulated biomass at lower than expected rates, suggesting local limiting factors, such as nutrient limitation. We find that soil carbon content is primarily a function of time and that altitudinal differences between the study sites do not play a role.

Abstract (sommario):

ABSTRACT:In Patagonia a Triassic-Early Jurassic Cordilleran interior magmatic belt preceded the widespread eruption of Middle Jurassic syn-extensional rhyolites. Two plutons (La Calandria and La Leona) represent the easternmost plutonic rocks of this belt, > 750 km east of the present oceanic trench. They define a high-K calc-alkaline monzonite series in contrast with the main Andinotype arc magmatism of the Pacific margin: they are enriched in large ion lithophile elements (K, Rb, Ba, Sr and Th), LREE and P2O5and depleted in HREE and Y, with low FeO*/MgO ratio. The range of observed compositions (56-76% SiO2) resulted from high-level fractionation of plagioclase, hornbleńde, biotite, K-feldspar and accessories (sphene, apatite and zircon).Initial87Sr/86Sr ratios, average εNdtand mean depleted-mantle Nd model ages of the two plutons are 0·70487, -0·5 and 1050 Ma for La Calandria and 0·70509, -1·4 and 1125 Ma for La Leona, respectively. They are thus isotopically more primitive than the Middle Jurassic rhyolites, previously attributed to partial melting of Mesoproterozoic mafic lower crust. The preferred model for the origin of the monzonites is remelting of an amphibole- + garnet-bearing, plagioclase-poor, high-K mafic source (?underplating). This occurred in a distal sector of a dying oblique subduction regime, immediately preceding the extensional silicic volcanism.

Abstract (sommario):

Abstract Communication, both intra-sector and among sectors, can generate dialogues and reciprocity and render development a public matter, i.e. a matter that pertains to all, including the media sector. However, it is still the case that we are faced with scattered social forces, unclear about their role in promoting inclusive, equitable and plural development. Those forces sometimes lack in democratic convictions or in significant social bonds among similarly minded groups. This article condenses years of reflection on our work at the Association of Social Communicators “Calandria”, a Peruvian civil society institution created in 1983 as the point of departure to argue that citizens should be the protagonists of development in a relationship with other key players, from government, the business community and organized civil society.

Abstract (sommario):

The LOCA (loss of coolant accident) is a kind of severe accident in the operation of PHWR (pressurized heavy water reactor) as well as other nuclear facilities, and possible cause of LOCA can be counted on the ballooning of pressure tube (PT) contacted to the outer calandria tube (CT) in the moderator system of CANDU-6 reactors. In the paper, we simulated the 150-kW experimental facility proposed by IAEA/ISCP, modeling the transient creeping behavior of pressurized tube heated with thermal radiation between the gaps of two concentric pipes. The outer boundary is simplified with a switched model that depends on the local temperature. With a multiphysical model supported by a commercial code, COMSOL multiphysics, the unsteady phenomena are simulated with models concerning various kinds of mechanics such as thermodynamics, nonlinear structural dynamics, and two-phase boiling heat transfer models.
