  1. 11. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bakhtiar Afzalan; [2021]
    Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Jennika Jädernäs; Erika Tjernberg; [2021]
    Keywords : Blågröngrå system; dagvattenhantering; regnbädd; skelettjord; kallt klimat; grön urban infrastruktur; klimatanpassning; ekosystemtjänster; gatugestaltning; landskapsarkitektur;

    Abstract : Det finns stora möjligheter och behov att kombinera urbaniseringens markanspråk med grön urban infrastruktur och i det arbetet säkra en hållbar dagvattenhantering. Att som landskapsarkitekt arbeta med detta är viktigt eftersom markanspråken ökar mängden hårdgjorda ytor i städer vilket samtidigt reducerar grön urban infrastruktur. READ MORE

    Abstract : Urban areas are responsible for a significant part of greenhouse gas emissions. Megacities, especially, have cumulative impacts due to different anthropogenic heat sources and urban heat island phenomena. It is therefore vital to replace fossil fuel burning heating sources with renewable sources in the current building stock. READ MORE

  6. 15. Cavitation analysis on test rig. : An experimental and CFD study executed in collaboration with Epiroc AB

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Oskar Kuoppala; [2021]
    Keywords : CFD; Cavitation; Water Hammer;

    Abstract : This master thesis project was done in collaboration with Epiroc Group Ab. Epiroc supplies high-quality drills of various types that can be used both above and below ground. A major problem in their percussive rock drills is that that cavitation is formed. Cavitation is a phenomenon that occurs when a fluid is subject to a sudden pressure drop. READ MORE
