SažetakKorišćenjem standardnih računarskih programa WIMS/D4, CITATION i RELAP5/MOD3.4, izvršena je analiza termo-hidrodinamike stabilnog stanja standardnog jezgra Pakistanskog istraživačkog reaktora-1 u funkciji od izgaranja nuklearnog goriva. Programi WIMS/D4 i CITATION upotrebljeni su za proračune neutronskih parametara, uključujući piking faktore i raspodele snage jezgra bez ksenona i jezgra sa ravnotežnom koncentracijom ksenona za različita izgaranja nuklearnog goriva. Program RELAP5/MOD3.4 korišćen je da se odrede temperature u centru goriva, u košuljici i hladiocu, radi obezbeđenja sigurnosti reaktora tokom gorivnog ciklusa. Proračuni potvrđuju da je reaktor siguran i da tokom gorivnog ciklusa nema započinjanja ključanja u jezgru, da se sa izgaranjem sigurnost povećava, a piking faktori opadaju.
