Description

The WWER-1000 system bahaviour during a leak from the pressurizer relief valve combined with a total loss of offsite power and a failure of the high-pressure pumps has been analysed. RELAP 4/06 and SSYST-2 codes are used. The changes in the most important thermophysical parameters of the primary coolant circuit, reactor core and the fuel elements under these conditions are examined. Tha data obtained indicate that the WWER-1000 fuel rods are not damaged by such transients. 3 figs., 3 refs
