Abstract

RELAP5 je alat koji korisnicima omogućuje modeliranje povezanog ponašanja sustava rashladne tekućine reaktora i jezgre za razne prijelazne trenutke i nesreće koje bi se mogle dogoditi u nuklearnom reaktoru te se koristi za analizu sigurnosti reaktora. LOFT postojenje je eksperimentalno postojenje dizajnirano da simulira ponašanje glavnih komponenata i reakcija sustava komercijalnih reaktora s stlačenom vodom (PWR) tijekom pretpostavljenih nesreća uzrokovanih gubitkom rashladne tekućine. L2-5 eksperiment bio je treći veliki eksperiment u LOCA uvjetima. Izveden je u lipnju 1982. godine. Eksperiment je simulirao 200%-tni prekid hladne cijevi komercijalnog PWR-a. Gorivo korišteno u L2-5 eksperimentu je dizajnirano da ima jednaka fizikalna, kemijska i metalurška svojstva poput komercijalnog goriva.

Abstract (english)

RELAP5 is a tool that allows users to model the related behavior of the cooling liquid reactor system and the core for various transients and accidents that may occur in a nuclear reactor. LOFT has been experimentally designed to simulate the behavior of major components and reactions of commercial pressurized water reactor (PWR) systems during presumed accidents caused by coolant loss. The L2-5 experiment was the third major experiment under LOCA conditions. It was performed in June 1982. The experiment simulated a 200% break in cold pipes of commercial PWR. The fuel used in the L2-5 experiment was designed to have one physical, chemical, and metallurgical properties like commercial fuel.
