Code-to-code comparison for analysing the steady-state heat transfer and natural circulation in an air-cooled RCCS using GAMMA+ and Flownex

Rousseau, P.G.,du Toit, C.G.,Jun, J.S.,Noh, J.M. North-Holland Pub. Co 2015 Nuclear engineering and design Vol.291 No.-

The GAMMA+ and Flownex codes are both based on a one-dimensional flow network modelling approach and both can account for any complex network of different heat transfer phenomena occurring simultaneously. However, there are notable differences in some of the detail modelling aspects, such as the way in which the convection in the reactor cavity is represented. Despite this, it was found in the analyses of the air-cooled RCCS system that the results provided by the two codes compare very well if similar input values are used for the pressure drop coefficients, heat transfer coefficients and view factors. The results show that the radiation heat transfer comprises the bulk of the total rate of heat transfer from the RPV surface. It is also shown that it is possible to obtain a stable and sustainable steady-state operational condition where the flow is in the reverse direction through the RCCS standpipes, resulting in excessively high values for the concrete wall temperature. It is therefore crucial in the design to ensure that such a flow reversal will not occur under any circumstances. In general the good comparison between the two codes provides confidence in the ability of both to correctly solve the fundamental conservation and heat transfer relations in an integrated manner for the complete RCCS system. Provided that appropriate input values are available, these codes can therefore be used effectively to evaluate the integrated performance of the system under various operating conditions. It is shown here that the RCCS should remain functional and continue to provide sufficient cooling even for very high blockage ratios at the inlet to the riser ducts, which supports the safety case.

Damage prediction in the vicinity of an impact on a concrete structure: a combined FEM/DEM approach

Jessica Rousseau,Emmanuel Frangin,Philippe Marin,Laurent Daudeville 사단법인 한국계산역학회 2008 Computers and Concrete, An International Journal Vol.5 No.4

This article focuses on concrete structures submitted to impact loading and is aimed at predicting local damage in the vicinity of an impact zone as well as the global response of the structure. The Discrete Element Method (DEM) seems particularly well suited in this context for modeling fractures. An identification process of DEM material parameters from macroscopic data (Young’s modulus, compressive and tensile strength, fracture energy, etc.) will first be presented for the purpose of enhancing reproducibility and reliability of the simulation results with DE samples of various sizes. The modeling of a large structure by means of DEM may lead to prohibitive computation times. A refined discretization becomes required in the vicinity of the impact, while the structure may be modeled using a coarse FE mesh further from the impact area, where the material behaves elastically. A coupled discrete-finite element approach is thus proposed: the impact zone is modeled by means of DE and elastic FE are used on the rest of the structure. The proposed approach is then applied to a rock impact on a concrete slab in order to validate the coupled method and compare computation times.

The Bilateral Cooperation between South Korea and Canada: Norms in Reality in Environmental Politics

이무성,김형민,David L. Rousseau 한국학술연구원 2013 Korea Observer Vol.44 No.1

Unlike previous decades, which stressed economic rationales in envisaging national environmental policies, Canada and South Korea have started to recognize each other as partners in environmental cooperation in the last twenty years. Canada seeks to preserve the environment at several critical junctures, while Korea has ardently pursued “low carbon, green growth” since the inauguration of the Lee administration in 2007. These two competing views can be summarized as the logics of consequentialism and appropriateness merit thorough explanations, respectively. With these logics in mind, this paper asks to what extent and under which conditions normative decision contributes to enhancing the bilateral relations. By doing so, the paper argues that the evolution of bilateral environmental cooperation can be attributed to ideational as opposed to material concerns. This contention is examined with particular reference to the two countries’ internal governance structure for environmental policy and the evolution of global environmental politics and governance.

NOVEL LARGE SCALE SIMULATION PROCESS TO SUPPORT DOT’S CAFE MODELING SYSTEM

A. MOAWAD,P. BALAPRAKASH,A. ROUSSEAU,S. WILD 한국자동차공학회 2016 International journal of automotive technology Vol.17 No.6

This paper demonstrates a new process that has been specifically designed for the support of the U.S. Department of Transportation’s (DOT’s) Corporate Average Fuel Economy (CAFE) standards. In developing the standards, DOT’s National Highway Traffic Safety Administration made use of the CAFE Compliance and Effects Modeling System (the “Volpe model” or the “CAFE model”), which was developed by DOT’s Volpe National Transportation Systems Center for the 2005–2007 CAFE rulemaking and has been continuously updated since. The model is the primary tool used by the agency to evaluate potential CAFE stringency levels by applying technologies incrementally to each manufacturer’s fleet until the requirements under consideration are met. The Volpe model relies on numerous technology-related and economic inputs, such as market forecasts, technology costs, and effectiveness estimates; these inputs are categorized by vehicle classification, technology synergies, phase-in rates, cost learning curve adjustments, and technology “decision trees”. Part of the model’s function is to estimate CAFE improvements that a given manufacturer could achieve by applying additional technology to specific vehicles in its product line. A significant number of inputs to the Volpe decision-tree model are related to the effectiveness (fuel consumption reduction) of each fuel-saving technology. Argonne National Laboratory has developed a fullvehicle simulation tool named Autonomie, which has become one of the industry’s standard tools for analyzing vehicle energy consumption and technology effectiveness. Full-vehicle simulation tools use physics-based mathematical equations, engineering characteristics (e.g., engine maps, transmission shift points, and hybrid vehicle control strategies), and explicit drive cycles to predict the effectiveness of individual and combined fuel-saving technologies. The Large-Scale Simulation Process accelerates and facilitates the assessment of individual technological impacts on vehicle fuel economy. This paper will show how Argonne efficiently simulates hundreds of thousands of vehicles to model anticipated future vehicle technologies.

French good practice guidelines for medical and occupational surveillance of the low back pain risk among workers exposed to manual handling of loads

Audrey Petit,Jean-Baptiste Fassier,Sandrine Rousseau,Philippe Mairiaux,Yves Roquelaure 대한직업환경의학회 2015 대한직업환경의학회지 Vol.27 No.-

Several clinical practice guidelines related to the assessment and management of low back pain (LBP) have been published with varied scopes and methods. This paper summarises the first French occupational guidelines for management of work-related LBP (October 2013). There main originality is to treat all the three stages of primary, secondary and tertiary prevention of work-related LBP. The guidelines were written by a multidisciplinary working group of 24 experts, according to the Clinical Practice Guidelines method proposed by French National Health Authority, and reviewed by a multidisciplinary peer review committee of 50 experts. Recommendations were based on a large systematic review of the literature carried out from 1990 to 2012 and rated as strong (Level A), moderate (B), limited (C) or based on expert consensus (D) according to their level of evidence. It is recommended to deliver reassuring and consistent information concerning LBP prognosis (Level B); to perform a clinical examination looking for medical signs of severity related to LBP (Level A), encourage continuation or resumption of physical activity (Level A), identify any changes in working conditions and evaluate the occupational impact of LBP (Level D). In case of persistent/recurrent LBP, assess prognostic factors likely to influence progression to chronic LBP, prolonged disability and delayed return to work (Level A). In case of prolonged/repeated sick leave, evaluate the pain, functional disability and their impact and main risk factors for prolonged work disability (Level A), promote return to work measures and inter professional coordination (Level D). These good practice guidelines are primarily intended for professionals of occupational health but also for treating physicians and paramedical personnel participating in the management of LBP, workers and employers.
