Group-average covariance matrices for the hafnium isotopes of interest for light water reactor applications

Funded under: FP7-EURATOM

Abstract

A consistent set of covariance matrices for the neutron cross-sections of {174}Hf, {176}Hf, {177}Hf, {178}Hf, {179}Hf and {180}Hf has been generated with results of a recent shape analysis performed on transmission data measured at the GELINA facility. The focus of this work is to propagate the Hf nuclear data uncertainties in specific reactivity worth measurements performed in the EOLE critical facility of the CEA Cadarache and to draw useful trends on the quality of the latest version of the European library JEFF-3.1.1.
