After the accident in Fukushima-Daiichi Nuclear Power Plants in 2011, deployment of spray and substitutional water inlet systems for cooling the spent fuels are recommended as safety measures against spent fuel pool (SFP) accident. In this work, analyses on an hypothetical accident which occurred by simultaneous lost of cooling ability and leaking of cooling water in SFP were conducted by using the severe accident code MAAP. For the counter measure optimization, water inlet condition to avoid cladding rupture was investigated.
