    • QUENCH FRONT PROPAGATION IN THE ANNULAR CHANNEL 

      Autor: Stepanek, Jan; Blaha, Vaclav; Dostal, Vaclav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      Understanding the quench front propagation during bottom core reflooding is crucial for the effective cooling during the LOCA accident. The results presented in this paper were obtained on an experimental loop with an ...

    • RADIATION DEGRADATION OF PCBS IN SEDIMENTS: COMPARISON OF TWO METHODS 

      Autor: Darážová, Ľubica; Šagátová, Andrea; Nečas, Vladimír; Fülöp, Marko; Han, Bumsoo
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      Polychlorinated biphenyls are toxic compounds which have accumulated in river sediments in Eastern Slovakia. Bioaccumulation could cause even cancer. Radiation degradation with electrons is new and perspective method to ...

    • SELF-ABSORPTION CORRECTIONS BASED ON MONTE CARLO SIMULATIONS 

      Autor: Johnová, Kamila
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      The main aim of this article is to demonstrate how Monte Carlo simulations are implemented in our gamma spectrometry laboratory at the Department of Dosimetry and Application of Ionizing Radiation in order to calculate the ...

    • STUDY OF IDENTIFICATION OF TWO-PHASE FLOW PARAMETERS BY PRESSURE FLUCTUATION ANALYSIS 

      Autor: Burian, Ondrej; Dostal, Vaclav; Vesely, Ladislav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      This paper deals with identification of parameters of simple pool boiling in a vertical rectangular channel by analysis of pressure fluctuation. In this work is introduced a small experimental facility about 9 kW power, ...

    • THERMAL-HYDRAULIC ANALYSIS OF IRT-4M IN REACTIVITY INSERTION ACCIDENT AT VR-1 REACTOR 

      Autor: Fejt, Filip
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      The paper deals with thermal-hydraulic analysis during reactivity insertion accident, i.e. a step increase of nuclear system reactivity by 0.7 eff, at VR-1 Reactor. The reactor utilizes IRT-4M type of fuel assemblies, and ...
