Improving Activation Cross Sections for Fusion Applications

摘要

High-quality nuclear data are required for reliable design calculations of fusion reactors as well as analyses related to safety, licensing, waste management, and decommissioning issues. The current work is focused on improving neutron activation cross-section data for nuclear reactions needed for fusion applications but also satisfying specific astrophysical needs. The cross-section data were evaluated on the basis of nuclear model calculation using the TALYS-1.8 code with varying nuclear model parameters. The evaluated data were compared to recent experimental data taken from EXFOR and other evaluated nuclear data libraries. Validation of the current evaluations has been performed using both differential and integral data sets. The updated cross-section data are going to be adopted into the new version of the TALYS Evaluated Nuclear Data Library.
