The verification test of flow induced vibration (FIV) in U-bend tube bundles of steam generator (SG) have been carried out using model steam generator, equipped with the large scale U-bend tube bundles, in a freon two-phase flow loop. The objectives of this program are to confirm the margin of FIV of SG U-bend and to advance the evaluation techniques of Thermal-hydraulic flow and FIV for SG U-bend. This report (Part 1) shows the experimental facilities which is included the modeling of a steam generator and the results of thermal-hydraulic test which is included the results of analysis. Another results are shown in Part 2 and Part 3 report. The conclusion of this paper is that void fraction and velocity profile of U-bend tube bundle are obtained in detail and analysis code (FIT-III) is verified very well by using these data. Therefore, it is considered that the results of FIT-III are valid for evaluation of flow induced vibration in actual SG.
