Two-Phase Flow Models of Gas Generation and Transport in Geological Formations

O. Silva [1]
[1] Amphos 21 Consulting S.L. - iMaGe Consortium, Barcelona, Spain

Gas generation and transport through porous media is a process common to many field applications such as radioactive waste and underground gas storage. In these operations, the gas phase evolution depends on the thermodynamic conditions at depth, the properties of the fluids (density, ... En savoir plus

Studies of Arc Volcanism and Mantle Behavior in Subduction Zones

C. Lee [1]
[1] Department of Earth and Environmental Sciences, Chonnam National University, South Korea

Injection of 3-D hot plume blob develops localized and short-term increases in slab surface temperatures, consistent with the Abukuma adakite, Northeast Japan. 3-D mantle flow develops trough of the lowered slab surface temperatures implying along lowered slab surface temperatures, ...

Exergy Analysis of Polymer Flooding in Clastic Reservoirs

A. Hassan [1], H. Bruining [2], T. Musa [3], R. Farajzadeh [2],
[1] Delft University of Technology, Delft, The Netherlands, and Sudan University of Science and Technology, Khartoum, Sudan
[2] Delft University of Technology, Delft, The Netherlands
[3] Sudan University of Science and Technology, Khartoum, Sudan

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... En savoir plus

Diverse Models for Graphite Brick Deformation and Stress State in UK AGR Nuclear Reactors

J. Burrow [1], A. Bond [1],
[1] Quintessa Ltd, United Kingdom

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of ... En savoir plus

Numerical Simulation of Quasi-steady-state Gas Flow in a Landfill

Q. Zheng [1],
[1] Zhejiang University, Hangzhou, Zhejiang, China

Landfill is currently the most dominating method to dispose wastes, which are caused by the lives of residents and constructions of cities and towns. Because of large amounts of organic substances in landfills, they will undergo continuous microbial degradation, which generates a lot of ... En savoir plus

Groundwater Flow and Solute Transport Modeling in the SFR Nuclear Waste Repository

E. Abarca[1], A. Idiart[1], O. Silva[1], L.M. de Vries[1], J. Molinero[1], F. Vahlund[2], H. von Schenck[2]
[1]Amphos21 Consulting, Barcelona, Spain
[2]Swedish Nuclear Fuel and Waste Management Co., Stockholm, Sweden

The Swedish Nuclear Fuel and Waste Management Company (SKB) operates the underground repository for low- and intermediate-level nuclear waste (SFR) located in Försmark, Sweden. An extension of the SFR is planned to accommodate mainly waste arising from the decommissioning of Swedish ... En savoir plus

An Innovative Reactive Transport Modeling Approach for the Chemical Evolution of a HLW Cell in the Callovo-Oxfordian Formation

J. Molinero[1], D. García[1], M. Grivé[1], A. Nardi[1]
[1]Amphos 21 Consulting, Barcelona, Spain

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of ... En savoir plus

Development of a COMSOL Application for the Efficient Evaluation of an Engineered Barrier System

D. Sampietro [1], E. Abarca [1], H. von Schenck [2], J. Molinero [1]
[1] Amphos 21 Consulting S.L., Barcelona, Spain
[2] Swedish Nuclear Fuel and Waste Management Co., Stockholm, Sweden

Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to ... En savoir plus

Thermal Performance of a Deviated Deep Borehole Heat Exchanger: Insights from a Synthetic Heat and Flow Model

M. Le Lous [1], F. Larroque [1], A. Dupuy [1], A. Moignard [2]
[1] ENSEGID, Bordeaux, France
[2] Fonroche Géothermie, Pau, France

Earth heat exchangers are drawing increasing attention and popularity due to their efficiency, sustainability and universality. In addition, DBHE can offer higher temperatures and more return on investment than conventional system. DBHE is also an alternative to geothermal power ... En savoir plus

Modeling Magnetic Induction from Transient Events Impinging upon a Conducting Moon
