Performance test and modeling with GAMMA-FR of helium circulator and recuperator for helium cooled breeding blanket

摘要

A helium circulator and a Printed Circuit Heat Exchanger (PCHE) type recuperator were developed for the helium cooling system (HCS) of a helium cooled breeding blanket for fusion reactor. Their full-scale components were manufactured and installed in the HeSS (Helium Supply System) facility at KAERI to perform qualification and performance tests. These components were tested to obtain performance curves for the circulator, and the effectiveness factor of the recuperator. Their component models were developed in GAMMA-FR based on design parameters and specifications. The results of performance testing were compared with corresponding simulations using GAMMA-FR to verify the components models. The simulation results shows good agreement with the test data. However, performance tests with a wide range of test conditions are required to better understand the performance of the components and further verification and validation of the models will be followed.
