This paper presents the findings of DECOVALEX 2023 Task F, which aimed to compare various models and conceptual approaches used in PA of a generic deep geologic repository in crystalline rock. The objective was to explore the contribution of modeling choices to uncertainty in PA model outputs. The study highlights the importance of characterizing the crystalline rock properties and the engineered barrier system in PA. The so-called reference case, a simplified version of a PA focused on the transport of two conservative tracers from the deposition hole to the surface, neglecting waste package performance was used as an example. Seven international teams (Canada, Czech Republic, Germany, Korea, Sweden, Taiwan, and United States) developed and simulated the generic reference case, tracking tracer releases from waste package locations to the near field and ground surface. Quantities of Interest (QOI) such as remaining tracer in the repository and fluxes across the domain were compared. Technical and time constraints led some teams to exclude parts of the engineered barrier system which resulted in faster release of tracers and radionuclides from the repository region. Comparing all models highlighted the importance of explicitly including drifts, buffer, and backfill in the reference case models. The results also emphasize the utility of a diverse set of modeling approaches in building confidence with performance assessment analysis.</div></div>","PeriodicalId":56008,"journal":{"name":"Geomechanics for Energy and the Environment","volume":"41 ","pages":"Article 100629"},"PeriodicalIF":3.3,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143132785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It utilizes a systematic and experimental approach to numerically simulate mechanical (M), hydro-mechanical (HM), and thermo-mechanical (TM) fracture processes in brittle rocks. The Task team introduced, applied, and compared a wide range of numerical methods, including both continuum and discontinuum methods, for simulating related fracture processes. Task G is based on three key experiments: the Freiberg, GREAT cell, and KICT experiments, which analyze M, HM, and TM processes respectively. Classic HM and THM benchmark exercises serve as a common basis by using analytical solutions for a plane line discontinuity in a poro-elastic medium (Sneddon and Lowengrub, 1969) and a point heat source in a thermo-poro-elastic medium (Booker and Savvidou, 1985), (Chaudhry et al., 2019). These solutions also serve as a reference for rough fractures and simple fracture networks. A systematic set of new benchmark cases has been derived based on the GREAT cell experiments. An analysis of the constant normal load (CNL) experiment has been conducted using micro- and macroscopic approaches, based on the Freiberg experiment. The GREAT cell experiments provided a database for evaluating the mechanical and hydro-mechanical responses of various rock samples (resin, greywacke, gneis) in triaxial tests with a rotational stress field. Fracture permeability was determined as a function of normal stresses in the rotational stress field. The KICT experiments were used to investigate thermally induced shear slip and dilation processes.

This method is independent of the influences from equivalent thickness of fracture, the meshing size, and the alignment between mesh and fracture. The methodology was first verified by modelling the flow and transport in a single fracture and compared with the analytical solutions. The ECPM model was then benchmarked with a series of test cases containing 4 connected deterministic fractures, with consistent comparison with the results of other modelling teams using different approaches.

Using linear stability analyses, we show that this channelling can autonomously emerge from the instability of the deformable interface between the injected gas and the compacted bentonite matrix driven by local stress concentration, pore dilation, and hydrologic gradient. Channel patterns formed would possess a fractal geometry. We further show that, once a percolating channel is established, the gas injected would percolate through the channel in a chain of gas bubbles, also due to the interface instability, resulting in periodic/chaotic variations in gas flow rate.

The PSC system is a sustainable infrastructure solution that utilises both solar and shallow geothermal energy. PSCs incorporate a network of pipes embedded in the asphalt layer to create a heat exchange layer. During warm months, water circulating through this layer captures solar heat, which can then be used for snow melting in winter, enhancing road safety, or for domestic and industrial heating applications. Finite Element (FE) analysis is a widely used method for evaluating the thermal response of PSCs to optimize their design. However, the substantial computational requirements of numerical modelling, especially for long-term time-dependent analyses, pose significant challenges in assessing the long-term thermal behaviour of PSCs. Surrogate models, approximating complex physics-based simulations, drastically reduce computational demands, enabling rapid and accurate evaluations of various design parameters and scenarios. In this study, a validated FE simulation framework was employed to generate data, which was then used to develop a data-driven surrogate model for PSCs. In order to refine the surrogate model's performance to its optimal level, hyperparameter optimisation was carried out. The comparison of outlet water temperature results between finite element and surrogate models showed a high correlation, with a coefficient of determination of 0.97 observed for both training and test data sets. Subsequently, the surrogate model was integrated as an objective function in a Particle Swarm Optimization (PSO) algorithm to automate the Heat Harvesting Capacity (HHC) optimisation of PSCs. The PSO algorithm demonstrates robust performance in identifying optimal solutions while also offering a substantial reduction in computational costs compared to FE simulations.</div></div>","PeriodicalId":56008,"journal":{"name":"Geomechanics for Energy and the Environment","volume":"40 ","pages":"Article 100617"},"PeriodicalIF":3.3,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142743894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
