Abstract:

The allusion in my title, of course, is to Marion King Hubbert's theory of “peak oil,” that moment in history when petroleum production reaches maximum output and then begins to decline. But Peak Freedgood is not Time's fool. It is an ever-fixèd mark: a quality or an intensity rather than a quantity; a stretch of Elaine Freedgood's work in which she is most like herself—when Elaineness production reaches maximum output. Such passages can be encountered in every book and article she's ever published, but the one I'll start with appears in a 2010 New Literary History essay called “Fictional Settlements” focused on Catharine Parr Traill's Canadian Crusoes (1852).

Abstract:

Katherine Magyarody, “‘Sacred Ties of Brotherhood’: The Social Mediation of Imperial Ideology in The Last of the Mohicans and Canadian Crusoes” (pp. 315–342) This essay analyzes narrative patterns of colonist-indigenous relations within Daniel Defoe’s Robinson Crusoe (1719) and two Robinsonade texts, James Fenimore Cooper’s The Last of the Mohicans (1826) and Catharine Parr Traill’s Canadian Crusoes (1852). Within the latter texts, the multiplication of Crusoe into “castaway” groups allows for an investigation of the social collateral of reaffirming racial hierarchies via settlers’ allegiance to indigenous individuals while destroying larger indigenous communities. In The Last of the Mohicans, the hybrid Cora Munroe and the Mohican Uncas’s love for her threatens the established pattern of homosocial interracial friendship; their deaths reaffirm racial boundaries. Conversely, by depicting a “coterie” of Scotch, French-Canadian, hybrid, and Mohawk members, Canadian Crusoes self-consciously rewrites the tragedy of Cooper’s novel so that sororal love enables cross-cultural marriage. Nevertheless, Traill’s proleptic descriptions of Canadian settlement mark her narrative as an alternate history that diverges from the progressive alienation of Native communities.

Abstract:

This thesis examines representations of Indigenous and non-Indigenous children that circulated through various reports, magazines, and fictional stories that were produced for and about children in Canada’s settler colonial context. Particularly, I focus on the archives of two related institutions, the interdenominational Canada Sunday School Union’s annual reports (1843-1876), and the Shingwauk Industrial Home’s monthly juvenile magazine, Our Forest Children (1887-1890), as well as two juvenile adventure narratives, Canadian Crusoes (1852) by Catharine Parr Traill and “The Shagganappi” (1913) by Emily Pauline Johnson (Tekahionwake). Through the nineteenth century, childhood emerged as a stage of development in the making of a racialized adult identity; I find that these archives and texts record uneasiness about racialized systems of feeling and reveal the colonial management regime’s preoccupation with strengthening certain affective bonds of relationality in order to naturalize dominant, Eurocolonial practices of kinship. My argument through this thesis follows and extends critical approaches to discourses of kinship from scholars interested in deploying Indigenous and postcolonial critiques of Western kinship traditions (Gaudry 2013, Justice 2018, Morgensen 2013, Rifkin 2010). These scholars variously draw on Michel Foucault’s theory of biopower, which they find to be central to the production and proliferation of the institution of settler colonialism in North America, and query how the biopolitical management of Indigenous people was constructed through particularized institutions (such as the residential school) and discourses (such as blood quantum). My project builds on this work by focusing on the representation of child-centered affect in Canada’s settler-colonial context. While kinship figures as a dominant narrative through this thesis, I argue that the figure of the child emerged as the node through which the colonial management regime worked out competing forms of kinship in Canada’s settler-colonial context. In the first chapter, I close read the content of the annual reports that were published by the Canada Sunday School Union. I focus specifically on the “technologies of transparency” that reveal the kinds of investments that were made in the lives of real-life settler children in Canada. The Union’s interest in tracking the circulation of Sunday school libraries, for instance, reflects an impulse to inculcate Christian feeling within the nuclear family. The second chapter builds on the colonial management regime’s investment in the emotional lives of children, but shifts the focus to the lives of the Indigenous children who attended the Shingwauk Industrial Home in Sault Ste. Marie through the late 1880s. I demonstrate how Reverend Edward F. Wilson utilized the generic codes of popular British juvenile magazines of the period to showcase how the home’s Indigenous students learn how to articulate appropriate expressions of Christian feeling. In chapter three, I draw attention to Catharine Parr Traill’s undertheorized juvenile adventure novel Canadian Crusoes. I argue that Traill represents vignettes of an Indigenous kinship practice in order to stage the incorporation of a young Kanien’kehá:ka woman into the Euro-Canadian family. Finally, the fourth chapter examines how Emily Pauline Johnson represents the incorporation of mixed-race children into the Canadian nation in her juvenile adventure novel, “The Shagganappi.” While scholars read “The Shagganappi” as a tale of successful racial-intermixture, I argue that such readings only serve to reinscribe the fantasy that Canada is comprised of a “mythical métissage” (Gaudry 85).

Abstract:

O ano era 1912, e um imigrante italiano e um grupo de irmãos provindos da aristocracia fazendeira encontraram-se nos escritórios sobre o famoso Café Guarany, no pulsante coração comercial da cidade, o Triângulo, para combinarem os trâmites à fundação da primeira fábrica de louças em faiança fina do país, em moldes industriais, produção em série e larga escala, no, então, rural bairro da Lapa. Assim teve início a história da Fábrica de Louças Santa Catharina, posteriormente Indústrias Reunidas Fábricas Matarazzo (IRFM) - São Paulo, que abarrotou a cidade de São Paulo com toneladas de louças brancas ou decoradas feitas em seus inúmeros fornos. Fundada no fulcro dos projetos de modernização para a Paulicéia tão desvairada, fábrica e louças dialogaram com as conjunturas das quais eram agência e estrutura. Formas e motivos espalharam-se pelos diversos consumidores da cidade, desbancando, muitas vezes, o monopólio da louça branca estrangeira, da qual se diferenciou produzindo-se segundo lógicas e tecnologias locais. Esta pesquisa baseia-se na análise do sítio arqueológico Petybon, no bairro da Lapa, cidade de São Paulo, região da Água Branca/Vila Romana, escavado no ano de 2003, que revelou ter sido o local de uma antiga fábrica de louças em faiança fina, inaugurada em 1913, fundada meio à maciça imigração italiana e o financiamento das indústrias pelo capital do café. Funcionou até 1937, já pertencente aos Matarazzo que a adquiriram em 1927. O local tem extrema relevância não apenas no contexto da Arqueologia Urbana no Brasil, como também enquanto exemplar dos primórdios da industrialização do país e da história da produção da louça nacional, parcamente tratada pela literatura, pouco valorizada e identificada, apesar de sua freqüência nos sítios arqueológicos do século XX.
The year was 1912, and an Italian immigrant and a group of brothers, drawn from an Aristocratic family farmer, met at an office above the famous Guarany Coffee House, in the beating heart of the city, the Triangle, to establish a fellowship and combine the procedures to the foundation of the first refined earthenware factory in the country, based on an industrial manufacturing, by a mass and large scale production, at the rural district of Lapa. That was the beginning of the history of Santa Catharina Pottery Factory, later Matarazzo United Manufacturing - São Paulo, who crammed São Paulo city with tons of white or decorated pottery, made in its many kilns. Forged at the center of modernizations project for the city, the pottery and factory dialogue with the contexts whose were agency and structure. Forms and motifs spread out by various consumers, beating, often, the foreign pearlware and whiteware monopoly, from whom it was distinguished by organizing itself according with its own logic and technology development. This research is based on the analysis of Petybon archaeological site, in the neighborhood of Lapa, São Paulo, at the region known as Água Branca / Vila Romana, excavated in 2003, which appeared to have been the site of one of the firsts refined earthenware factories, opened at 1913, founded through the massive Italian immigration and the financing of industries by coffee profits. Worked until 1937, then belonging to the Matarazzo Family, who acquired it in 1927. The site is extremely important not only in the context of Brazilian Urban Archeology, but also as an example of the early industrialization in Brazil and the history of national pottery industry, barely treated by literature, almost unknown and unappreciated, despite its frequency at Brazilian archaeological site from the 20th century.

The genus Ololygon belongs to Hylidae and currently includes 47 species, which are divided into two groups. The Ololygon catharinae species group is composed by 34 species. In the present work, we describe a new species of Ololygon belonging to O. catharinae species group, which has its identity supported by morphological and bioacoustic characters. The new species, here treated as Ololygon sp., is characterized by its medium size (male CRC 24.39-28.79 mm, female 33.11 – 38.76 mm), snout subovoid in dorsal view, vocal slit present in males, hypertrophied forearm, absence of externally differentiated glands in the inguinal region, and flanks and hidden surfaces of thigh with irregular dark brown spots on pale yellowish background. Short advertisement call (call duration 0.29 - 0.90s), characterized by a series of 4–11 pulsed notes, with 1–11 pulses per notes, peak energy between 2067-3100 Hz. We recognize three types of call in Ololygon sp. Tadpole presents oral disc with small dorsal gap in marginal papillae, a biseriate row of marginal elongated papillae, oral formula 2(2)/3 and internal oral morphology not very different from that described for other tadpoles of the genus Ololygon. The new species is known only at the municipality of Sítio d'Abádia, state of Goiás, Central Brazil. We noted that some acoustic parameters were influenced by the body condition of males, temperature and humidity. The dominant frequency was the only acoustic variable classified as static and, for all acoustic parameters showed more variability among-males than within-males, having potential for individual recognition.
O gênero Ololygon pertence à família Hylidae e, atualmente, inclui 47 espécies, divididas em dois grupos. O grupo Ololygon catharinae é composto por 34 espécies. No presente trabalho descrevemos uma nova espécie de Ololygon pertencente ao grupo de espécies O. catharinae, a qual tem sua identidade suportada por caracteres morfológicos e bioacústicos. A nova espécie, aqui tratada como Ololygon sp., é caracterizada pelo tamanho corporal moderado (CRC macho 24.39–28.79 mm; fêmea 33.11–38.76mm), focinho subovóide em vista dorsal, presença de fendas vocais, antebraço hipertrofiados, ausência de glândulas externamente diferenciadas na região inguinal, e regiões do flanco e parte interna da coxa com manchas irregulares marrom escuro sobre fundo amarelo pálido. Canto de anúncio curto pulsionado, com duração de 0.29 – 0.90s, caracterizado por uma série de 4 – 11 notas pulsionadas, com 1-11 pulsos por notas e pico de energia entre 2067–3100 Hz. Exitem três vocalizações distintas em Ololygon sp. Girino com disco oral com pequena interrupção dorsal, papilas marginais alongadas e dispostas em duas séries, fórmula oral (LTRF) 2(2)/3 e morfologia oral interna pouco distinta da descrita para outros girinos do gênero Ololygon. A nova espécie é conhecida apenas para o município de Sítio d’Abádia, Estado de Goiás, Brasil Central. Alguns parâmetros acústicos do canto de anúncio de Ololygon sp. foram influenciados pela condição corporal dos machos, temperatura e umidade. A frequência dominante foi a única variável acústica com propriedade estática e, para todos os parâmetros acústicos, foi observada maior variabilidade interindividual do que intraindividual. Todos os parâmetros acústicos podem atuar no reconhecimento entre os indivíduos.

Abstract:

Abstract A predictive transient one-dimensional rotodynamic pump model is currently developed into the CATHARE-3 thermal-hydraulic system code at CEA Saclay, France. Flow is computed in each part of the pump (suction, impeller, diffuser, volute and discharge pipe) based on the definition of a mean stream line. Several cells are used to mesh each part of the rotodynamic pump, which makes this model different from usually called “1D models”. In this study, the model is tested on a medium specific speed centrifugal pump in every operating modes encountered in the first quadrant (positive flow rate and rotational speed). A flow rate evolution is performed at the nominal rotational speed and also at rotational speed equal to zero in order to produce complete first quadrant homologous curves. Relative discrepancy between computation and experiment is respectively less than 10% and 15% on the whole obtained homologous head and torque curves.

Abstract:

The loss of coolant accidents with core degradation e.g. TMI-2 and Fukushima demonstrated that the nuclear safety analysis has to cover accident sequences involving a late reflood activation in order to develop appropriate and reliable mitigation strategies for both, existing and advanced reactors. The reflood (injection of water) is possible if one or several water sources become available during the accident. In a late phase of accident, no well-defined coolant paths would exist and a large part of the core would resemble to a debris bed e.g. particles with characteristic length-scale: 1 to 5 mm, as observed in TMI-2. The French “Institut de Radioprotection et de Sûreté Nucléaire” (IRSN) is developing experimental programs (PEARL and PRELUDE) and simulation tools (ICARE-CATHARE and ASTEC) to study and optimize the severe accident management strategy and to assess the probabilities to stop the progress of in-vessel core degradation at a late stage of an accident. The purpose of this paper is to propose a consistent thermo-hydraulic model of reflood of severely damaged reactor core for ICARE-CATHARE code. The comparison of the calculations with PRELUDE experimental results is presented. It is shown that the quench front exhibits either a 1D behavior or a 2D one, depending on injection rate or bed characteristics. The PRELUDE data cover a rather large range of variation of parameters for which the developed model appears to be quite predictive.

The paper presents the methodology adopted to assess the Interim Safety Analysis Report (ISAR) of the Belene NPP in the framework of the contract between the Bulgarian Nuclear Regulatory Authority (BNRA) and RISKAUDIT (IRSN&GRS). It stresses the in-depth analysis carried-out for several relevant-to-safety issues and illustrates in some detail the investigation of the Large Break Loss of Coolant Accident (LB LOCA) with loss of power and failure of the active part of the Emergency Core Cooling System (High Pressure and Low Pressure Safety Injection pumps), performed with the French best estimate thermal-hydraulic code CATHARE. The role, problems and efficiency of the passive and active safety systems during the accident scenarios are discussed. Finally, the main conclusions of the safety evaluation of the Belene NPP project are summarized.

Abstract:

The ASTRID (Assessment of Source Term for Emergency Response based on Installation Data) process model is used for the faster than real-time prediction of the radioactivity released into the containment and further into the environment in case of an emergency situation in a light water reactor. Combined together with the containment module COCOSYS the model can predict the entire radioactivity release chain from the primary system to the containment and further into the environment. In the paper the ASTRID thermohydraulic module PROCESS is presented shortly. The thermohydraulic part is a fast running solution for the drift-flux based thermohydraulics. In high temperatures the core degradation leading to the melt pool formation in the reactor barrel and reactor vessel lower head is calculated in the in-vessel module RELOMEL. Finally after the reactor vessel wall has been eroded due to the molten corium in the lower plenum, the massive radioactivity release occurs into the containment. But even before this scenario the radioactivity may be transported from the superheated core to the containment by the coolant. The reference plants for the development have been the Westinghouse type 4-loop PWR, the French type 3-loop PWR, The German type 4-loop Konvoi PWR, the Loviisa VVER type PWR, and the Olkiluoto type internal pump BWR. The reference code for the DBA thermal hydraulics has been the SMABRE code. In the developmental assessment the capability of the rough nodalization of ASTRID has been tested against the SMABRE nodalization describing the plants with 50–500 nodes. For the developmental assessment of the in-vessel severe accident the sample cases are calculated with MELCOR. The more thorough validation is based on the internationally known system codes, RELAP5, MELCOR, CATHARE and ATHLET. In the validation the most problematic area is the radioactivity transport into the containment. This part of the validation is done with the integrated code system.

Abstract:

The last test of the international Phebus Fission Product (FP) program, named FPT-3, has been performed in November 2004 at Cadarache. It used boron carbide as absorber material, instead of Ag-In-Cd in the previous tests. Such absorber material is used in power plants like BWR, VVER, some western type PWR and EPR, and the importance of its effects on the main degradation phenomena is still to be assessed. This paper relates the main experimental events issued from the test together with the interpretation work coming out from code calculations. Several results were unexpected and some are of importance for safety analyses, particularly concerning cladding oxidation and fuel degradation. The test interpretation has been undertaken with the ICARE2 code, developed by IRSN “Institut de Radioprotection et de Suˆrete´ Nucle´aire”. ICARE2 is the stand alone part of the mechanistic ICARE/CATHARE code, built for safety analyses purposes. In the last code versions, models deal with the degradation and the oxidation of the B4C control rod. Already validated against QUENCH experiments, these models have been applied to the Phebus FPT-3 conditions. Calculations show that, although general trends of the test are very well reproduced, specific effects concerning the interaction of B4C with the neighbouring rods cannot be calculated. Better detailed physical analysis and prediction capabilities of calculation tools are expected to come out from the International Source Term Program, in particular from the results of the BECARRE separate-effect-tests performed at IRSN. Though the detailed modelling of such interactions has still to be improved, the Phe´bus FP series of integral experiments have proved the capability of the program to significantly improve our understanding of the source term issue and important aspects of core degradation.

Abstract:

In the event of a severe accident in a nuclear reactor, the oxidation, dissolution and collapse of fuel rods is likely to change dramatically the geometry of the core. A large part of the core would be damaged and would look like porous medium made of randomly distributed pellet fragments, broken claddings and relocated melts. Such a complex medium must be cooled in order to stop the accident progression. IRSN investigates the effectiveness of the water re-flooding mechanism in cooling this medium where complex two-phase flows are likely to exist. A macroscopic model for the prediction of the cooling sequence was developed for the ICARE/CATHARE code (IRSN mechanistic code for severe accidents). It still needs to be improved and assessed. It appears that a better understanding of the flow at the pore scale is necessary. As a result, a direct numerical simulation (DNS) code was developed to investigate the local features of a two-phase flow in complex geometries. In this paper, the Cahn-Hilliard model is used to simulate flows of two immiscible fluids in geometries representing a damaged core. These geometries are synthesized from experimental tomography images (PHEBUS-FP project) in order to study the effects of each degradation feature, such as displacement and fragmentation of the fuel rods and claddings, on the two-phase flow. For example, the presence of fragmented fuel claddings is likely to enhance the trapping of the residual phase (either steam or water) within the medium which leads to less flow fluctuations in the other phase. Such features are clearly shown by DNS calculations. From a series of calculations where the geometry of the porous medium is changed, conclusions are drawn for the impact of rods damage level on the characteristics of two-phase flow in the core.

Abstract:

For the study of the Heterogeneous Inherent Boron Dilution transient in a Pressurized Water Reactor, a Small Break Loss Of Coolant Accident (SB-LOCA) is postulated. Natural Circulation (NC) may be interrupted and, under Reflux-Condenser (RC) conditions, the steam formed in the core condensates in the Steam Generator (SG) U-tubes: a boron-depleted slug may accumulate in the crossover leg and in the SG outlet chamber. If NC restarts as the Reactor Cooling System (RCS) is refilled, boron-depleted slugs might be transported to the Reactor Pressure Vessel (RPV) and to the core. The mixing of the boron depleted slug with the borated water in the Cold Legs (CLs), downcomer and lower plenum after Restart of Natural Circulation (RNC) is quantified by means of Computational Fluid Dynamics (CFD) analyses. The CFD code STAR-CD is used to perform this analysis. Boundary conditions for this calculation — especially the boron-depleted slug size and the NC restart mass flow rate — are extrapolated from PKL experimental findings. The initial conditions are derived from an overall plant analysis performed with the CATHARE system code. Buoyancy effects, both in the cold leg and in the downcomer, are very significant phenomena for the evaluation of the slug transport and mixing: the hot (saturation temperature) boron-depleted water slug tends to accumulate in the upper parts of the cold legs and in the upper part of the downcomer (above the cold legs), before being pushed and dragged down. The boron concentration distribution at the core inlet during the transient, evaluated with STAR-CD, is compared with a critical value in order to check that boron concentration at the core inlet is always above the threshold necessary for the core to remain subcritical.

Abstract:

For the Reactor Pressure Vessel (RPV) assessment and lifetime evaluation of the nuclear plants, French Utilities apply a series of calculations including thermal-hydraulic, thermo mechanical and fracture mechanics studies in order to study the Pressurized Thermal Shock (PTS) in the downcomer caused by the safety injection. Within the frame of the plant lifetime project, integrity assessments of the French 900 MWe (3-loops) series RPV have been performed. A gain for safety margins to fast fracture of the RPV can be found with a 3D modeling of thermal-hydraulics loads. From a physical phenomena point of view, the results of the system code analysis (CATHARE computation) of the PTS transient induce two kinds of scenarios: single phase and two-phase flows in the cold leg. In the case where the cold legs are partially filled with steam, it becomes a two-phase problem and new important effects occur. Thus, an advanced prediction of RPV thermal loading during these transients requires sophisticated two-phase, local scale, 3D codes. For that purpose, a program has been set up to extend the capabilities of the NEPTUNE_CFD two-phase solver which is the tool able to solve two-phase flow configuration. At the same time, a simplified approach has shown that for this kind of scenario where the cold leg is weakly uncovered, a free surface calculation (without phase change) was sufficient to respect the necessary criteria of safety. Considering the time duration of 3D computation and the large number of cases, EDF and AREVA-NP decided to share the effort. The two teams use the NEPTUNE_CFD code (coupled with the thermal solid SYRTHES code) for thermal-hydraulic computations. The thermo mechanical code used is CALORI. According to this approach and to reduce the CPU time, two computations have been performed for 2″ and 3″ Small Break Loss Of Coolant Accident (SBLOCA) on a one-third RPV model. Computations on a complete RPV model have been performed to demonstrate the relevance of the one-third RPV model. The studies have been performed by two independent teams from EDF and AREVA-NP. The investigated configuration corresponds to the injection of cold water in the RPV during a penalizing representation of a primary break transient and its impact on the solid part formed by cladding and base metal. Numerical results are given in terms of fluid temperature in the cold legs and in the downcomer. The obtained numerical description of the transient is used as boundary conditions for a full mechanical computation of the stresses. The results show that such a complete thermal-hydraulic and mechanical 3-dimensional analysis improves the evaluation of the consequences of the loading on the stress fields and eventually the margins to fast fracture of the RPV. The good agreement observed between a one-third RPV model and a complete RPV model results confirms the validity of the approach.

Abstract:

In the general context of the nuclear activities, life extension of the existing plants is the interesting option for countries that are already well equipped with NPPs. As the working life of 60 years is now expected possible for some well maintained plants, their safety measures needs to be improved such that they should be comparable to the new or future designs, taken into account the results from the probabilistic and the deterministic accident analysis. To accomplish this aim, the Accident Management (AM) is the important part of the process that must be utilized including possible automation of some processes. At INSTN, the extensive sensitivity studies related to the feed and bleed process on the primary and the secondary side had been carried out with the SIPACT simulator, based on the Cathare code, for a 900 MWe pressurized water reactor. The simulations had been mainly conducted for the Beyond Design Basis Accident (BDBA) condition. This condition included the total loss of feed-water and a small break with the loss of the high pressure injection system (HPIS). From these studies, several interesting findings had been obtained. For AM purpose and with the bleeding process, the criterion called “the safety time margin” for core uncovery was introduced. By plotting the safety time margin against the bleeding time, the relation between them was established and used to optimize, when possible, the AM measures. For the scenario that involved the total loss of feed water, in case of full bleeding, a window was found for the bleeding time around the degradation of the heat exchange in SGs would be resulted. In this scenario, one of the solutions was to open only one relief valve at first in order to let through only the minimal mass. At the time of the injection by the accumulator, the other two relief valves were then opened. As a result, the flow through the relief valves could be effectively compensated by the flow from the accumulator, the mass balance in the vessel was maintained and the safety margin time was increased. For the scenario that was related to a small break without HPIS, the concept of the safety time margin was still applicable. The time window was observed to be narrower for the bleeding on the secondary side if the core uncovery was to be avoided, however. By observing the distribution of the mass in the primary loop, its behavior, which was directly related to the design, was fully demonstrated. One important finding showed that the current PWR design presented some disadvantage under the BDBA condition. Due to the way the water was accumulated in various components, sometime as much as that that was still remained in the pressure vessel, not all the water already presented or injected into the primary loop could reach the pressure vessel to be effectively utilized for core cooling. In order to characterize the availability of the water to cool the core, which related to the NPP BDBA robustness, a simple mass distribution criterion was proposed. Some improvements for the future design were also suggested.
