Table 2

C/E ratios for the prediction of the Neodymium buildup, after fluence scaling. Results obtained in the present work with the JEFF-3.1.1 library are compared with those obtained with the JEFF-3.1 library [18]. The 1st and 2nd weighted mean values for PROFIL were calculated with and without the C/E results obtained for the 235U sample number 19 located in the core midplane (z = 0 mm). The quoted uncertainties are the experimental uncertainties coming from the chemical analysis of the 235U samples.
