The future of nuclear power depends on the interests and
decisions. To take the relevant deep uncertainty into account, a new
methodology of robustness analysis of fuel cycle strategies has been
developed. The method has been applied to the French cycle, considering
the future deployment of fast reactor as the pre-selected objective and
an uncertain change, called disruption, towards a new objective: the
minimization of transuranic inventories without fast reactor. The status
of plutonium is contradictory in two cases. Two approaches of
identifying robust strategies were tested, which correspond respectively
to the static and adaptive robustness assessment. One identifies static
strategies in a pre-disruption scenario, which achieve acceptable
outcomes for both objectives. The other takes a trajectory pursuing the
pre-selected objective and, in case of disruption, adapts it for the new
objective. The comparison of two approaches indicates the temporality of
adaptation relative to immediate actions under the uncertain disruption.
