Abstract EN
The safe storage of spent fuel assemblies in the spent fuel pools is very important.
These facilities are not covered by leaktight containment; thus, the consequences of overheating and melting of fuel in the spent fuel pools can be very severe.
On the other hand, due to low decay heat of fuel assemblies, the processes in pools are slow in comparison with processes in reactor core during LOCA accident.
Thus, the accident management measures play a very important role in case of some accidents in spent fuel pools.
This paper presents the analysis of possible consequences of fuel overheating due to leakage of water from spent fuel pool.
Also, the accident mitigation measure, the late injection of water was evaluated.
The analysis was performed for the Ignalina NPP Unit 2 spent fuel pool, using system thermal hydraulic code for severe accident analysis ATHLET-CD.
The phenomena, taking place during such accident, are discussed.
Also, benchmarking of results of the same accident calculation using ASTEC and RELAP/SCDAPSIM codes is presented here.
