An ACME test rack comprises aloop system and equipment completely simulating a prototype nuclear power plant, a system and equipment completely simulating a prototype nuclear power plant passive reactor core cooling system, a system and equipment partly simulating a reactor secondary circuit and a system and equipment partly simulating a reactor loop and connected with the reactor loop, wherein the loop system and equipmentcompletely simulates loop layouts of a four-in pipe and a two-out pipe of the prototype nuclear power plant, and the system and equipment completely simulating the prototype nuclear power plant passive reactor core cooling system proportionally simulates layouts and pipeline routs of the system and equipment.

Description

technical field [0001] The invention relates to the field of nuclear power tests, in particular to an overall performance test platform for a large-scale advanced pressurized water reactor passive core cooling system. Background technique [0002] The CAP1400 nuclear power plant is a third-generation large-scale advanced pressurized water reactor nuclear power plant independently developed by my country. It adopts a passive safety system to deal with nuclear power plant accidents and ensure the safety of the reactor. The "passive" design concept is a major innovation in the design of the safety system of the PWR nuclear power plant. It makes full use of the natural characteristics of the material, such as gravity, natural circulation, compressed gas expansion and other natural forces, and does not require pumps, AC power, 1E level The emergency diesel engine, as well as the corresponding support systems such as ventilation and cooling water, greatly simplifies the safety sys...

AI Technical Summary

Problems solved by technology

There are large distortions in the friction loss, system heat loss, and metal heat storage in the full pressure, thin and tall benches, and there is no theoretical analysis guidance for the simulation of local thermal-hydraulic phenomena.

One of the main reasons is that for passive systems, some local thermal-hydraulic phenomena are more important and more complex. The original power volume is an overall and macro design method, which cannot be used for detailed local phenomena. good deal

This method still has some gaps in the requirements of complex and comprehensive proportional analysis of large-scale integral passive test systems
