Abstract

The present report outlines the approaches and the results of new contributes to the validation effort of the two activation code packages ANITA-2000 and EASY-99 (Fispact99), that have been done in the frame of the EFDA Task No. TW3-TSS-SEA5.5: A. The validation of the Anita-2000 code package and, more generally, of the SCALENEA-1 sequence calculation, against Data from Low-Activation Repository (Baita-Bihor) has been performed. The calculation results are in good agreement with the experimental ones: the discrepancies are, generally, within the experimental uncertainties (up to 40%). Discrepancies less than 1% have been found between Sn SCALENEA-1 spherical surface detector and Monte Carlo MCNP 4C results on the lateral surface. Discrepancies less than 2% have been found between Sn SCALENEA-1 cylindrical surface detector and 2D-Sn DORT results on the central radial surface. B. ANITA-2000 and EASY-99 code packages have been validate against experimental data from ENEA FNG (Fusion Neutron Generator) shut down dose rates measurements. Discrepancies between experiment and calculation are within 25% both for Anita and Fispact. Differences between the two code calculation are within 2% As a general conclusion, the SCALENEA-1 calculation sequence both with the ANITA-2000 and the EASY-99 is able to provide reliable results for various ITER safety analysis purposes like waste management assessment. Moreover, experimental data from the cemented containers of the ENEA-Trisaia SIRTE waste storage have been collected and processed for a possible further step in the ANITA-2000 validation process. Detailed data (as the radioisotope content) for a significant sample of drums will be processed in a next future to make possible the contact dose rate evaluation in the various positions outside the cemented drum container and the comparison with the experimental data.
