Experiments on heat transfer and fluid flow in a once-through steam generator were conducted with the model test rig simulating real reactor conditions of an integral type marine reactor. Steady state experiments concerning the pressure drop and heat transfer characteristics of feed water flowing through subcooling, boiling and superheating regions, and instability experiments concerning the flow oscillations of feed water were conducted. Kozeki's predictions were best fitted to the experimental data for frictional pressure drop along boiling region. Heat transfer coefficients along boiling region were in the ranges of 10^4〜10^5 kcal/m-2h℃. Flow instability occurring in the present experimental rig was a typical density wave oscillation dominated by the frictional pressure drop along superheated region. Instability threshold was well expressed with the correlation between entrance throtting coefficients in heat transfer tube and the length of boiling region.
