Abstract

The invention relates to a pool type liquid metal reactor test system design method and device, belongs to the field of reactor thermohydraulics, and solves the problem of large error of a heat transfer analysis method in the prior art. The design method comprises the following steps: determining the space size of an air cavity of a test device and the physical property parameters of a structural material based on consistency of geometric similarity conditions and hot end boundary conditions; on the basis of geometric similarity, argon pressure intensity, air gap size, thermal insulation material thickness and reactor top ventilation parameters of an air cavity space are determined, it is guaranteed that heat flow density and thermal resistance are equal in the heat transfer process, and a temperature field consistent with a reactor prototype is obtained. According to the invention, the temperature field of the test system is consistent with that of the prototype, and basis and support are provided for establishment of the test system with heat transfer characteristics consistent with that of the reactor.

Description

technical field [0001] The invention relates to the technical field of reactor thermal hydraulics, in particular to a design method and device for a pool type liquid metal reactor test system. Background technique [0002] Due to its high safety and economy, the liquid metal reactor has become the main reactor type for the development of the fourth generation reactor in my country. In the design and construction of nuclear reactors, it is necessary to obtain the temperature load of the reactor under different working conditions as the input conditions for thermal stress calculation, to judge whether the structures and components in the reactor can meet the structural integrity under the design working conditions, and to ensure the reactor Safe to run. [0003] In the heat transfer of the pool liquid metal reactor, the heat transfer characteristics of the inert protective gas space on the top of the main vessel are the most complicated. In the existing research methods of h...
