“…determined, considering a minimum contribution of 1%. All the data regarding dominant radionuclides and pathways are taken from both reports/papers devoted to calculate SDDR at different ITER locations [1,2,[5][6][7][8][9][10], and own calculations carried out to complete the information of those materials partially or not analyzed in the literature. These calculations are performed using the ACAB activation code [12] with the EAF-2007 activation library and the SA2 irradiation scenario [13].…”

Abstract. This paper explores the quality of available activation cross section (XS) data for accurate Shutdown Dose Rate (SDDR) prediction in the ITER Port Cell and Port Interspace areas, where different maintenance activities are foreseen. For this purpose the EAF library (2007 and 2010 versions) has been investigated, as it is typically used by the ITER community.Based on both reports/papers on SDDR in ITER and own calculations, major nuclides contributing to the SDDR coming from the activation of i) relevant materials placed in ITER and ii) candidate materials for the bioshield plug as L2N and barite concretes, are identified. Then, relevant production pathways are obtained.EAF XS quality for all pathways is checked following the procedure used for validating and testing the successive EAF versions. Also, possible improvements from using the TENDL-2015 library are assessed by comparing EAF and TENDL XS with available differential experimental data from EXFOR. Results point out that most of the activation XS related to materials currently placed in ITER are reliable, and only a few need improvement. Also, many of the XS related to both L2N and barite concretes need further work for validation.

“…Specifically, EAF-2007, which is typically used and recommended for the ITER SDDR calculation [1,2,[5][6][7][8][9][10] is explored. Furthermore, the effect of possible improvements of EAF-2010 and TENDL-2015 libraries on the SDDR calculation is investigated.…”
