Verification of the new implementations in SHARKX against TSUNAMI to perform pinpower UQ and representativity analysis

The effect of the input uncertainty in UQ and RA is also investigated by comparing the results obtained with the variance-covariance matrix (VCM) of ENDF/B-VII.1, JENDL4.0 and SCALE6. The choice of input VCM is the major source of result discrepancies for UQ on kinf and pinpower. However, for RA, it is found to be of the same order of magnitude than the method discrepancies, i.e. the differences between SHARKX and TSUNAMI coming from the “implicit effect”.
