Considered as a suitable solution for non-proliferation and
reprocessing purposes, UMo fuel has been chosen and studied by the RERTR
program since 1996. Involved in the RERTR fuel developments since 1978, with
more than 20 years of U3SI2 fuel production, and closely
linked to the French Commissariat à l'Energie Atomique, CERCA was able to
define properly, from the beginning, the right R&D actions plan for UMo
CERCA has already demonstrated during the last 4 years its ability to
manufacture plates and fuel elements with high density UMo fuel. UMo full size
plates produced for 4 irradiation experiments in 3 European reactors afforded
us a unique experience.
In addition, as a main part of our R&D effort, we have always
studied in depth a key part of the CERCA process outline which is the plate
rolling stage. After some preliminary investigation in order to define the
phenomenological model describing the behavior of the fuel core when rolling,
we have developed a rolling digital simulator.
