ANALIZA ZAGOTOVITVE VARNOSTNE MEJE PRED KRITIČNOSTJO BAZENA ZA IZTROŠENO GORIVO NUKLEARNE ELEKTRARNE KRŠKO PRI HIPOTETIČNIH DEGRADIRANIH POGOJIH
Povzetek
V prispevku je predstavljena analiza starih rešetk bazena za iztrošeno gorivo Nuklearne elektrarne Krško ob hipotetičnih degradiranih pogojih bazena. Upoštevano je vretje hladilne vode in primer optimalne nevtronske moderacije ob predpostavki, da ni raztopljenega bora v hladilu. Za preračun transporta nevtronov je uporabljen program MCNP verzija 6.1.0 in ACE knjižnica nevtronskih presekov evaluirana iz ENDF/B‐VII.1 podatkov. Analizirani so primeri štiri od štirih in tri od štirih zapolnjenih lokacij v rešetki bazena. Kjer je bilo potrebno, so bile določene omejitvene krivulje izgorelosti.
