Fuel pin life evaluation for the multiduct test assembly in FFTF
A multiduct fuel pin test assembly (MFTA) has been developed for the breeder reactor fuel development programs in the Fast Flux Test Facility (FFTF) at HEDL. The MFTA, designed as a test vehicle consists essentially of two fuel pin regions, the inner test pin region and the outer driver pin region separated by the inner and the intermediate ducts. The objective of this report is to analyze and to determine to what extent the driver pins in the outer region of MFTA can be operated beyond the three reactor operating cycles (300 EFPD) set for the standard FFTF driver pins, so that the MFTA as a test vehicle can be reused for further irradiation tests. The analysis is to demonstrate that the driver pin cladding structural integrity can be maintained during an intended life by taking into account all possible operating conditions, namely, the normal steady-state and the most severe expected transient events.
