To verify the irradiation performance of the HANARO
fuel at a high power and a high burnup, in-pile
irradiation tests were performed. Two test fuels for a
higher burnup irradiation and one test fuel for a higher
linear heat rate had been designed and fabricated. All
the test fuel assemblies were made of 6 fuel elements
located in the outer ring of the hexagonal fuel assembly
and 30 aluminum dummy elements. The test fuel assemblies
were irradiated in the HANARO core. The maximum
discharged burnup and linear power were 69.9 at% average
and 85.5 at% peak with an 83 kW/m average and 121.6 kW/m
peak, respectively. Detailed non-destructive and
destructive PIE, such as the measurement of the burnup
distribution, fuel swelling, clad corrosion, dimensional
changes, fuel rod bending strength, micro-structure,
etc., were performed. It was verified through the
irradiation tests that the HANARO fuel maintains a
proper in-pile performance and integrity even at a high
power of 121 kW/m and up to a high burnup of 85 at %.
