Abstract

Abstract

Based on the design of a million-kilowatt nuclear power plant, this article analyzed the possible late primary circuit reinjection scenarios in severe accidents when the In-Vessel Retention (IVR) measure is taken (that is, when the lower head of the pressure vessel has formed a melting pool), and studied the primary circuit pressure respond to the late reinjection. Through the comparative analysis of the condition with no reinjection, the influence of reinjection time, reinjection flow and the opening number of pressure relief valves in serious accidents on the pressure of the primary circuit were comprehensively evaluated, the influence law of each measure was obtained, and suggestions were put forward for severe accident management strategies.
