  1. 1. 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

  3. 2. Bevattning i vallodling

    University essay from SLU/Dept. of Soil and Environment

    Author : Gabriel Thor; [2020]
    Keywords : grovfoder; vattenbrist; torkstress; torka; bevattningsdamm; försommartorka;

    Abstract : Denna litteraturstudie handlar om hur bevattning påverkar vallens av-kastning. Det är ett viktigt ämne att diskutera efter den extrema sommaren 2018. Med klimatförändringarna är det troligt att säsongerna blir mera vari-erande, trots det måste grovfoderförsörjningen till våra lantbruksdjur säk-ras. READ MORE

  4. 3. Life and strife of modern organic farmers : cases from Sweden, Cambodia, and Bali

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

    Author : Filippo Valsecchi; [2019]
    Keywords : agriculture; WWOOF; ethnography; multicase study; typology; new social movement; risk; habitus;

    Abstract : Organic farming forms an integral part of the current environmental discourse of “saving the planet” through more ecological forms of cultivation and lifestyle. Yet, beneath this common denominator, the global organic movement encompasses an impressive spectrum of experiences varying along such factors as geographical loca-tion, farm size, work organization, personal attributes, institutional framework, busi-ness style, normative ideals, and farming techniques.

  5. 4. A Hybrid Approach to GPS-Free Geolocation over LoRa

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Jonas Danebjer; Valthor Halldórsson; [2018]
    Keywords : Technology and Engineering;

    Abstract : The last few years have seen a rapid expansion within the area of the Internet ofThings (IoT). For many IoT applications, such as asset tracking and distributedsensor networks, the problem of localization (i.e. determining the physical loca-tion of nodes in the network) is fundamental.

  6. 5. Degradation mechanisms of UN and UN–10U3Si2 pellets of varying microstructure by comparative steam oxidation experiments

    University essay from KTH/Reaktorfysik

    Author : Selim Uygur; [2016]
    Keywords : Uranium Mononitride; Uranium Silicide; Composite; Steam degradation; corrosion mechanism;

    Abstract : During an extended LOCA in a LWR, the current UO2 fuel reaches very high temperatures and eventually melts, while the current Zircaloy fuel cladding oxidizes releasing hydrogen. These two consequences can lead to an unacceptable amount of radioactive release by presenting accident routes for containment failure. READ MORE
