A1 Bogoslovskaya, Galina Pavlovna T1 Experimental and Computational Investigations of Heat Transfer and Stability of Boiling Liquid Metal in a Model of an Array of the Fast-Neutron Reactor Fuel Elements JF Heat Transfer Research JO HTR YR 2001 FD 2001-04-01 VO 32 IS 1-3 OP 9 AB The paper presents and analyzes experimental and calculated data on the boiling of a sodium-potassium heat carrier in an array of simulators of fuel elements in a loop with natural circulation which models the conditions of operation of a fast reactor in the regime of accidental cooling. At different mass flow rates of a heat carrier, three regimes of boiling were obtained: a stable (bubble) regime at the initial stage of boiling, then a pulsing (slug) regime which, on increase in the power supply, passed into the second stable (mist) regime of boiling.
