Abstract

U ovom radu analizirani su termohidraulički parametri u primarnom krugu NE Krško dobiveni simulacijom nesreće dvostrukog loma cjevovoda DVI sustava. Simulacija je obavljena programom RELAP5 i za njega već ranije razvijenom nodalizacijom NE Krško. Za početak je opisan program RELAP5, njegove osnovne značajke, matematički modeli i jednadžbe koje koristi pri proračunu. Zatim su opisani dijelovi NE Krško i njihove poveznice s kontrolnim volumenima razvijene nodalizacije. Protumačena je i važnost simulacije nesreća u nuklearnim postrojenjima te je detaljnije opisana nesreća dvostrukog loma DVI cjevovoda. Za kraj su priloženi grafički rezultati simulacije, koji su ukratko i prokomentirani.

Abstract (english)

In this paper, the thermohydraulic parameters in the primary circuit of the Krško NPP obtained by simulating a double ended guillotine break of a DVI system pipeline are analyzed. The simulation was performed with the RELAP5 program and the previously developed nodalization of NPP Krško. Firstly, basic features, mathematical models and equations of the RELAP5 program used in the calculation are described. What follows is the description of the Krško NPP systems and components, and their connections with the control volumes of the developed nodalization. The importance of accident simulation in nuclear plants was also explained, and the double ended guillotine break of the DVI pipeline was described in more detail. Finally, graphical results of the simulation are attached, which are also briefly discussed.
