Abstract
The Spent Fuel Pool (SFP) in a nuclear power plant is a robust structure
designed to withstand large seismic loads. After the terrorist attacks on September
11 and the accident in the Fukushima nuclear power plant, special attention was
focused on safety assessments and taking measures to mitigate possible accidents
related to the spent fuel pool. This paper will provide an insight into spent fuel pool
loss of coolant phenomenology and consequence mitigation strategies. Model of NPP
Krško SFP was presented in MELCOR code which has been used as a case-study for
evaluating accident propagation. The calculations were carried out using the latest
version of MELCOR code which was updated for the analysis of severe accidents in
nuclear spent fuel pools.
