The European Activation System (EASY) has been continuously developed and improved formore than 20 years. Its primary purpose is to carry out neutron- proton- and deuteron-induced activation calculations in support of nuclear technology, particularly for nuclear material selection, design and optimization. It comprises the EAF nuclear data libraries and the FISPACT inventory code. For fusion applications, materials used for the construction of ITER, particularly plasma facing components, will be submitted to intense neutron irradiation. These materials may be evaluated using EASY for their nuclide inventory, He gas production and decay heat production over time, for example. EASY includes data to 60 MeV, making it also relevant for IFMIF analysis, and now covers 66,256 reactions. Such large libraries require an extensive validation process, which includes the statistical analysis of cross sections (SACS) and comparisons with differential and integral data. The suite of these methods has now been extended to evaluate the next library release, EAF-2010. Furthermore, significant attention has been focused on improving the uncertainty file, a unique feature of EAF libraries. In this work we discuss recent data improvements to be included in EAF-2010 and extensions to the treatment of uncertainties both in EAF and within EASY.
