A nondestructive method making use of X-ray computer tomography (X-ray CT) has been applied to post irradiation examinations (PIEs) of fast breeder reactor (FBR) fuel assemblies. In the X-ray CT system, a 12 MeV X-ray pulse was used in synchronizatio

The helium releases were investigated in FBR fuel pins irradiated to high burn-up. The released amounts increased with the increase of burn-up, but no burn-up dependence of their release fraction to total amounts generated was seen. The contents of 2

Fission gas release in FBR MOX fuel pins irradiated to high burnup was studied as a function of burnup. Fuel pellets of different microstructures were fabricated by three methods. The pin averaged burnup of fuel pins ranged from 5.8 to 144 MWd/kgM. T

Distributions of volatile fission products and microstructures were studied at different axial positions in or near the fuel-cladding gap of FBR MOX fuel pins irradiated up to pin average burn-up of 110.6 GWd/t. It was found that most of the volatile

In order to study the dependence of the gap width change on the burn-up, the fuel-to-cladding gap widths were investigated by ceramography in a large number of FBR MOX fuel pins irradiated to high burn-up. The dependence of gap widths on the burn-up
