Analysis of the steam generator for the safe integral reactor concept: II. A linearized non-steady state model

Abstract

Based on an earlier steady state model, a linearized non steady state model of the Safe Integral Reactor (SIR) steam generator is developed. Two models are derived for the nucleate boiling regime. In the first model it is assumed that any changes in the heat addition or loss or flow perturbations will affect only the vaporization or condensation. In the second model, the saturation temperature, and hence the saturation pressure, is allowed to change. Finally, the response of the steam generators to steam valve perturbation is compared for the SIR and the H. Robinson reactors.
