  1. 1. Validation and Application of CFD to Safety-Related Phenomena in Lead-Cooled Fast Reactors

    Författare :Marti Jeltsov; Pavel Kudinov; Walter Villanueva; Dmitry Grishchenko; Afaque Shams; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Verification; Validation; Calibration; Sensitivity Analysis; Uncertainty Analysis; CFD; STH; Code Coupling; Liquid Lead Coolant; LFR; SGTL R; Bubble transport; Core voiding; Seismic Sloshing; Melting Solidification; Physics; Fysik;

    Sammanfattning : Carbon-free nuclear power production can help to relieve the increasing energy demand in the world. New generation reactors with improved safety, sustainability, reliability, economy and security are being developed. Lead-cooled fast reactor (LFR) is one of them. LÄS MER

  3. 2. Estimating Probability Distribution by doing Computer Experiments

    Författare :Gunnar Kjell; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer simulations; seismic verification; response spectrum prediction; stratified sampling; latin hypercube sampling; variance reduction; variance estimation; seismic verification;

    Sammanfattning : In almost every field of engineering, advanced computer programs are used. In many cases only the probability distributions of the input variables to the programs are known. Sometimes stochastic processes are used as input, for example if the stresses in a construction due to an earthquake are to be calculated. LÄS MER

  4. 3. Feature Extraction for Low-Frequency Signal Classification

    Författare :José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; multimodal data space; Atomic physics; Atomfysik; Electronics;

    Sammanfattning : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. LÄS MER

  5. 4. The Applicability of Geoelectrical Methods in Pre-Investigation for Construction in Rock

    Författare :Berit Ensted Danielsen; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole geophysics; Pre-investigation; Geoelectrical imaging; Applied geophysics; Value of Information Analysis VOIA ;

    Sammanfattning : Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. LÄS MER
