As a result of 28 years of operation of nuclear research reactor
IRT-2000 some amount of spent nuclear fuel has been produced. At this moment 73
spent fuel assemblies are stored in the spent fuel storage pool, albeit without
forced circulation.
To solve the problem with the spent nuclear fuel shipping to its
country of origin some activities in technical and administrative aspects are
carried out.
Visual inspection, dosimetry and gamma-spectrometry measurements have
been performed with the aim to establish the physical state, possible corrosion
on the cladding and residual activity of the spent nuclear fuel.
Also some corrosion problems occurring due to prolonged
non-adequate storage of spent fuel are discussed and a result from X-ray
structure analysis and some photo are given in the paper.
