Abstract

The paper presents the analysis of steam generator feeding by mobile pump under power unit total blackout with loss of heat removal to the ultimate heat sink. Thermohydraulic model of NPP with VVER-1000/320 for RELAP5/MOD3.2 was used in calculations. The assessment of hydraulic loss of mobile pump head was performed based on initial data of Zaporizhzhya NPP Unit 1. Results of thermohydraulic calculations confirmed the effectiveness of SG feeding via mobile pump at an early and late stages of the accident and revealed typical aspects of the transient progression.
