Description
Cooling of the reactor core is needed for a certain period of time after reactor shut-down. The time of core cooling depends on the time and power of operation, as well as on the thermal capacity of the reactor core and the permitted moderator and fuel temperature. Thermal capacity of the RA reactor core is 3,46 kWh/deg C, and permitted core temperature increase is 60 deg C. The objective of this paper was to determine the period of restarting the moderator circulation in for after-heat removal from the core
Abstract (Serbian)
Posle zaustavljanja reaktora potrebno je izvesno vreme hladiti aktivnu zonu. Vreme hladjenja aktivne zone zavisi od duzine rada i snage na kojoj je reaktor radio pre zaustavljanja, a takodje i od velicine toplotnog kapaciteta aktivne zone i visine dozvoljene temperature moderatora i goriva. Toplotni kapaciteti aktivne zone reaktora RA iznosi 3,46 kWh/deg C, a granica dozvoljenog porasta temperature aktivne zone je 60 deg C. Cilj ovog rada je brzo i jednostavno odredjivanje perioda ponovnog ukljucivanja cirkulacije moderatora radi hladjenja zagrejane aktivne zone usled delovanja zaostale snage (author)Files
