 \subsection{CLASSFuelPlan}
 If you don't want to change the fuel type (from a fixed fuel to an other, a fixed fuel to a reprocessed one, changing the final burnup of a fuel...) inside a reactor during its operation stay away from this part.\\
-The aim of this class is to allow user to change the fuel parameter during the operation of the reactor, by example setting a reactor with a UOX fuel enriched at 3\% for 3 cycles, then changing to 5\% UOX or even to MOX. All fuel in a CLASSFUelPLan are associated to a burnup. The reactor updating his cycle time to this burnup( considering the power remain the same in a reactor during all its life.\\

 The usage of the CLASSFuelPlan is quiet simple... On just need to add to an existing CLASSFuelPlan, a time (to perform the fuel switch), a fuel and an associated burnup. One should note that the fuel in the reactor only change at the end of a cycle (finish the current cycle even after a date to change fuel type.)\\
