FBTR MOX

The dataset provided by IGCAR (India) in the framework of IAEA CRP T12031” FUEL MATERIALS FOR FAST REACTORS (FMFR) (2019-2023)”.

Datasets of the irradiation test carried out in FBTR to study the performance of MOX fuel composition and pin dimensions with shorter length.

For the test, configuration was chosen with a 37-fuel pin bundle cluster in a FBTR Subassembly. The MOX fuel pin was irradiated at a peak Linear Heat Rating (LHR) of 450 W/cm and the peak burn-up was 112 GWd/t. Fuel used is having 29% PuO2 & U in UO2 is enriched with 53.5% U-233 to simulate the LHR. The fuel pin clad OD was 6.6 mm and ID was 5.7 mm. The fuel pellets were 5.56 mm in OD with a central hole diameter of 1.8 mm. Active fuel column length was 240 mm as against 320 mm for FBTR fuel column. Top of the fissile column of the test pin was in level with the top of the FBTR core.

Pin No.: 0041 is selected for the benchmark analysis in the CRP FMFR.
