Abstract:
FTL (Fuel Test Loop) is a test facility which could conduct fuel irradiation test at HANARO reactor. The fuels can be tested in the IR1 irradiation hole of HANARO under the commercial power plant operating conditions. The FTL is composed of an IPS (In-Pile test Section) and an OPS (Out Pile system). The conceptual design of the FTL started at the end of 2001 and the detailed design was finished by March 2004. The installation of FTL was finished successfully on March 2007. The commissioning of the FTL will be conducted by January 2008. The FTL would be used for the irradiation test of high burn-up PWR fuels from 2008. The design characteristics and the installation of the FTL facility are introduced in this paper. The application fields of the FTL are as follows.
- Nuclear fuel irradiation behavior test at the operating condition of the commercial power plant
- Fuel burn-up and mechanical integrity verification
- Irradiation data generation for the analysis model
- Technical improvement of design and fabrication for the advanced fuel development
- Fuel rod irradiation test for performance verification.
