Embodiment Construction
[0043] The present invention is described in further detail below in conjunction with accompanying drawing:
[0044] refer tofigure 1 and figure 2 , the reactor primary loop coolant flow field, temperature field and stress field coupling calculation method of the present invention comprises the following steps:
[0045] 1) According to the high temperature gas-cooled reactor core and steam generator drawings, use the CAD modeling tool embedded in cmosol to construct the high temperature gas-cooled reactor core model and steam generator model with the same size as the actual equipment, among which, image 3 is the geometric model of the reactor core, Figure 4 is the geometric model of the steam generator, in which, for the fast convergence of the computational domain, the characteristics of symmetric structures are applied, image 3 The middle geometry is a Mitsubishi prism, and its volume is 1 / 30 of the actual stack volume; Figure 4 The internal heat transfer tube struct...
