ADS Nuclear Data, Final Report of the n_TOF-ND-ADS Project

Project ID: FIKW-CT-2000-00107
Funded under: FP5-EAECTP C


The design of innovative accelerator driven systems (ADS) for incineration of nuclear waste and energy generation requires the complete knowledge of basic cross sections for neutron induced processes. For design purposes, these data need to be derived in a consistent, accurate and cost-effective way, to be evaluated and made available in a way compatible with simulation tools and industry practices in general. The main goal of the n_TOF-ND-ADS Project has been to produce and disseminate high precision cross section data for the majority of the isotopes relevant to the waste incineration and the ADS design. This included capture and fission cross sections for the minor actinides, capture cross sections for the main fission products and (n,xn) reactions for structural and coolant materials. These objectives have been obtained by using three core technologies: an innovative high-energy spallation source built at CERN (the CERN n_TOF facility), high performance detectors and DAQ systems, and stateof-the-art computer engineering.
In this report, a description of the design studies, the realization, and performances of the CERN neutron time-of-flight facility is given together with an overview of all the experimental devices developed for measurements of high-resolution neutron cross section data. A brief account of all the measurements performed at n_TOF in its commissioning phase and in the three experimental campaigns performed in 2002, 2003 and 2004 is given.
