ABSTRACT

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.
