  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

  2. 2. 3D-modeling of swing check valve with connection to dynamic behavior used in system studies

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Keywords : Swing check valve; fluid mechanics; pressure surge; waterhammer; Fluent; Technology and Engineering;

    Abstract : This Master’s Thesis is the result of the collaboration between The Technical Faculty of Lund University and TÜV NORD Sweden AB. Focus has been directed towards the nuclear industry where this thesis is one of several other Master’s Theses regarding the dynamic modeling of a swing check valve. READ MORE

  3. 3. TRACE Analysis for Transient Thermal-hydraulics of A Heavy Liquid Metal Cooled System

    University essay from KTH/Kärnkraftssäkerhet

    Author : Yiqiong Shao; [2011]
    Keywords : ;

    Abstract : Heavy liquid metal (HLM - lead or lead bismuth eutectic) is considered as a candidate coolant for next-generation fast reactor and accelerate-driven systems (ADS), due to its favorable chemical, thermo-physical and neutronic properties in comparison with sodium which has been used as coolant in fast breeder reactors (FBRs). To perform design-base-accident analysis for the HLM-cooled reactors, the well-known transient thermal-hydraulic analysis codes (e. READ MORE

  4. 4. Hydraulic Transient in a Pipeline (Using Computer Model to Calculate and Simulate Transient)

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Mosab Elbashir; Samuel Amoah; [2007]
    Keywords : soil mechanics; offshore technology; Hydraulic Transient; Pipeline; Unsteady Flow; Computer Model; FORTRAN Language; hydraulic engineering; Civil engineering; Väg- och vattenbyggnadsteknik; Technology and Engineering;

    Abstract : A hydraulic transient, which is a flow condition where the velocity and pressure change rapidly with time, can collapse a water distribution system if that system is not equipped with adequate transient protection device(s). The occurrence of transients can introduce large pressure forces and rapid fluid accelerations into a water distribution system and if the system is not well protected, it can fail. READ MORE
