Abstract

U ovom radu obradio sam temu testiranja nuklearne elektrane na sigurnost postupkom CILRT testa. Kroz rad je obrađen temeljni standard za provođenje postupka. Zatim je analizirana provedba testa takvog tipa nad zaštitnom posudom nuklearne elektrane Krško. Odabran je software paket GOTHIC za provedbu simulacije testa. Simulacijom su se u postojećem GOTHIC modelu zaštitne posude verificirali i nadogradili određeni dijelovi. Nakon simulacije u modelu su sadržane sve pukotine, te se buduće analize... More mogu provoditi s takvim modelom uzimajući u obzir utjecaj proračunatih pukotina na konačne rezultate. Kao test modela na fizikalnost, napravljen je pokus unošenja poremećaja koji nije karakterističan za CILRT test. Simulacijom je dokazana dosljednost modela i potvrđena je nefizikalnost analiziranog poremećaja. Less

Abstract (english)

In this thesis I wrote about CILRT test as a key component for nuclear containment safety analysis. I started this thesis by explaining the basics of the test, and also the standard for it which is provided by the ANSI/ANS organization. After the basics of the standard, I explained the test procedure that was executed on NPP Krško in 2016. Then, after the explanation on a real NPP, I continued my thesis through a simulation in the software package named GOTHIC. I took an existing GOTHIC... More containment model and verified or upgraded some parts of it. After multiple iterations of simulations, I got some characteristics of, so called, ruptures in the containment. This way all the future analysis on this model will have ruptures included as a part of the system, which is good because we can now test some other cases on the model and see how those ruptures affect the results. As the last part of thesis, I executed another test on the model. I have put a unusual disruption into the model, and measured the results then, so I can be sure that the model stays consistent even when the unusual disruption occurs. Less
