Dryingimpacts the delayed behavior of the containment vessels. Many tests of loss of mass are available in the data base of Electricite de France or in the literature and make it possible to evaluate profiles ´ of water content in a test tube. The macroscopic retiming of the drying parameters and the uncertainty level on the latter force to carry out a sensitivity analysis over the lifespan of the vessel. The ranking of the input parameters (sensitivity analysis) was carried out using an expansion of the model response onto the polynomial chaosbasis(nonintrusiveregressionmethod)andcomputingtheSobol’indicesanalyticalyfromthepolynomial chaoscoefficients.
