Abstract

The report presents the analyses done, in the frame of the EFDA Task No. TW5-TSS-SEA4.1 (milestone 2) during the year 2005 to support the PACTITER code validation needs The results include the reaction rates and the isotope activities of the 316LN steel test tubes that were irradiated in OSIRIS reactor (CEA-Saclay) during January 2004 and then inserted in CORELE-2 loop (CEA-Cadarache) for ITER material corrosion tests and PACTITER code validation. PACTITER The report describes also the approach that has been used for. A neutron model has been preliminarily set up to perform the radiation transport analysis with the SCALENEA-1 sequence and to identify (through a comparison with experimental neutron flux data from the OSIRIS team) the suitable neutron flux spectra for ANITA-2000 activation calculations. A comparison of the ANITA-2000 activation calculation results with experimental activity measures performed on the irradiated test tubes and with calculation performed at CEA using the CASTOR code is also presented. That comparison indicates a good agreement between experimental data and calculations. Moreover, because from years 2005 to 2007 new experimental corrosion measurements of the test tubes irradiated into the OSIRIS reactor are foreseen in CORELE-2 loop, some predictions on the expected tube material activity parameters up to the year 2008 are presented.
