Sodium reacts chemically with water in case of unexpected tube failure of steam generator (SG) in fast breeder reactor (FBR), exoergic reaction produced reaction field with high temperature and high corrosive (sodium-water reaction). Adjacent tubes in the field have possibility of rupture by inner pressure. It is integral to predict the event with high accuracy that we understand characteristics of heat transfer inside tube in detail. Experimental study has been carried out and clarify characteristics of heat flux and temperature on inner wall under low mass flow rate and high subcooling.
