Abstract

Considerable interest has been focused on the boiling water reactor as a possible reactor type from which low cost electrical power can be produced. In connection with the design of boiling water reactors, it is necessary to obtain information concerning the interrelationship existing between various system parameters such as pressure, poser density, steam volume fraction, steam quality, recirculation rate, density of steam-water mixtures, slip ratios in both upcomers (risers) and downcomers, subcolling, etc., on natural and forced circulation boiling systems. Iterative processes are generally required for the calculations of this kind of problem and therefore high speed computer programs are desirable. To the author's knowledge, no computer program taking into account the problem of steam carryunder in the downcomer which is of significance for a natural circulation boiling system without the use of mechanical devices to separate the steam and liquid phases, is available at the present time. This program has been checked by hand calculation for the sample problems given in this paper.
