Software Development and Validation for Design and Analysis of Sodium-Sodium Heat Exchanger

The research is dedicated to the calculation method and vibration criterion of the intermediate heat exchanger in fast breeder reactor. The gaps in the vibration design verification of this type of equipment were supplemente. The relevant design verification manual were formed. The reliable support and guidance for the vibration safety design of the equipment were provided. Corresponding vibration analysis programs were developed in conjunction with research results to facilitate analysis and design. The core computational modules are the module for the calculation of the natural frequencies and modal data of the formations required in the calculation of the rheological vibrations, as well as the harmonic response and random vibration module.
