Sažetak

U radu je prikazan pregled "strategije skaliranja", posebno uloge usaglašene test metodologije. Da bi se ukazalo na pojave značajne za skaliranje izložena su nova proučavanja koja se bave analizama skaliranja u lakovodnom reaktoru sa posebnim osvrtom na ruski reaktor VVER 1000. Usvojeni pristup skaliranju zasniva se na odabiru nekoliko karakterističnih parametara na osnovu njihovog značaja za ponašanje tranzijenta. Korišćen je računarski program RELAP5/Mod.3.3, i kvalitativnim i kvantitativnim procenama pokazana je njegova tačnost. Upoređivanjem eksperimentalnih podataka utvrđeno je da se ispitivana postrojenja slično ponašaju u pogledu vremenskih tokova, i da se mogu kvalitativno predvideti iste termohidrauličke pojave. Glavni rezultat je da osnovni parametri PSB i LOBI postrojenja pokazuju slične trendove. Ova činjenica potvrđuje valjanost usvojenog pristupa skaliranja i pokazuje da je ponašanje PWR i VVER reaktorskih tipova vrlo slično. Uprkos činjenici da su dva postrojenja različito projektovana, tokom usaglašenog testiranja nisu uočene nove pojave, dok su ranije poznate činjenice programom ispravno predviđene. Mogućnosti i tačnost programa su nezavisni od razmere. Obe ove osobine su nužne da bi se u cilju predviđanja ponašanja nuklearne elektrane dopustili proračuni u pravoj razmeri.
