Heat transfer characteristics inside tube caused by sodium-water reaction in FBR steam generator

Kurihara, Akikazu ; Ohshima, Hiroyuki; Yanagisawa, Hideki*

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 are exposed to the reaction field and have possibility of overheating rupture by inner pressure with reduction of material strength. It is integral to predict the event with high accuracy that we understand characteristics of heat transfer inside tube in detail. Rapid heating experiment equivalent to sodium-water reaction has been carried out under high pressure, low mass flow rate and high subcooling, Heat flux and temperature on inner wall were estimated correctly by inverse problem solution. As the result of present study, we confirm heat transfer characteristics inside tube qualitatively.
