초록

KAERI has been developed a conceptual design of the PGSFR, the pool-type sodium cooled fast reactor. The intermediate heat exchanger is located in the primary heat transport system and transfers heat generated from reactor core from primary heat transport system to the intermediate heat transport system. KAERI developed a one-dimensional code for design and performance analysis of an intermediate heat exchanger. Computational fluid dynamics simulations were performed to validate this code and analyze three-dimensional heat flow. In the case of temperature, the code and CFD results were very similar and the pressure was slightly different, the code was modified compared with the experimental results. The problem caused by temperature imbalance founded in tube-side outlet chamber of the IHX was solved by incorporating the flow mixer.
