ABSTRACT
In February 2005 in the MIR reactor the irradiation
tests of LEU U-Mo pin-type mini fuel elements fabricated
at the Bochvar Institute were completed within the
framework of collaboration with ANL under RERTR program.
The fuel element cross-section represents a 2.98×2.98
mm square, cladding material is aluminum alloy SAV-1,
height of the fuel element active part is ≤ 200 mm,
uranium volume density in the fuel composition is ~ 4
and ~ 6 g/сm3. Totally, 71 undersized
pin-type fuel elements were tested including 13
different modifications that differed in the fuel
composition characteristics. To obtain data on the fuel
behavior at different burnups, several mini fuel element
groups were irradiated up to different burnup values
ranging from ~ 20% to ~ 70% of 235U burnup.
This paper presents the main irradiation tests and
PIE results that have been obtained by now.
