1. 1. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

   University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

   Author : Clara Eklund; [2023]
   Keywords : PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

   Abstract : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. READ MORE

3. 2. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Matilda Tiberg; [2022]
   Keywords : Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

   Abstract : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. READ MORE

4. 3. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Maryam Shakibi; [2022]
   Keywords : drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

   Abstract : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. READ MORE

5. 4. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Haoyang Dong; [2022]
   Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

6. 5. Infiltration, hydrogeology, and heterogeneity - Management of pressure and flow: A case study for the Varberg tunnel project

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Lisa Risby; [2020-07-08]
   Keywords : short duration hydraulic tests; hydraulic conductivity; radius of influence; infiltration; heterogeneity; confined and unconfined aquifer;

   Abstract : This thesis aims to describe a conceptual model of the sedimentology for Swedish (or nordic) conditions of heterogeneous aquifers but focus is on a case study in Varberg. This to facilitate the identification of main water-bearing units (e.g. READ MORE
