Loss-of-coolant-accident analysis for the Ignalina RBMK-1500 Nuclear Power Plant

A loss-of-coolant-accident (LOCA) analysis has been completed for the Ignalina nuclear power plant (INPP) located in northeastern Lithuania near the borders of Latvia and Belorus. The INPP site has two RBMK-1500 reactors; the RBMK-1500 is a boiling water, graphite-moderated, pressure tube reactor with the capability of producing up to 4800 MW(thermal). Currently, the power level of INPP is limited to 4200 MW(thermal); thus, the analysis results presented in this paper have been obtained for an initial power level of 4200 MW(thermal).
