Ob"em i dostovernost' eksperimental'nykh dannykh po termodinamicheskim svoistvam sistem U–O, Zr–O i U–Zr–O, a takzhe po rastvorimosti kisloroda v rasplavlennykh urane i tsirkonii nedostatochny dlya postroeniya termodinamicheskoi modeli vzaimodeistviya rasplavlennogo koriuma so splavami na osnove Fe. V kachestve modeli rasplava mnogokomponentnogo koriuma, sostoyashchego iz metallov i metalloidov, predlozheno rassmatrivat' atomarnyi rastvor zameshcheniya, obladayushchii svoistvami regulyarnogo rastvora. Neobkhodimye dlya etogo parametry vzaimodeistviya atomov metallov s kislorodom opredelyayutsya iz analiza ravnovesiya oksidnogo i metallicheskogo rasplavov v eksperimentakh serii STFM-Fe. Sformulirovannaya v rezul'tate model' pozvolyaet sdelat' prognoznye otsenki vzaimodeistviya rasplava U–Zr–O-koriuma s zhelezom.
