ABSTRACT
Pin-type fuel elements loaded with LEU UO2 and U-Mo in Al matrix are being tested. A detailed description of the tested FEs was previously presented by Y. I. Trifonov (VNIINM) at the RERTR-2002 meeting.
The standard WWR-M5 reactor fuel assemblies and the experimental assemblies substantially differ in their loading, enrichment, hydraulic resistance and specific heat-exchange surface. This report briefly describes the main operations aimed at testing the experimental FEs in the WWR-M reactor.
Experimental data and the evidence that the standard WWR-M5 FEs of the WWR-M reactor and the experimental assemblies can work together are presented.
A test method is described. The results of the tests in the experimental reactor loop before loading into the core are presented. The initial level of FEs' non-integrity is determined.
