Long-lived activity of elements: Effect of new activation cross- sections and their uncertainties on the selection of materials for IFE reactors

Evaluation of HYLIFE-II and Sombrero using 175- and 566-group neutron transport and activation cross sections

“…A total of 127 radionuclides differ by at least 10% and 25 differ by at least an order of magnitude. This confirms findings reported in previous work such as that by Sanz et al [8].…”

Effect of activation cross-section uncertainties on the radiological assessment of the MFE/DEMO first wall

“…Several efforts have previously addressed the effect of activation XS uncertainties in the accuracy of isotopic inventory calculations for inertial fusion energy (IFE) applications [1,2]. In these works, a sensitivity-uncertainty analysis and a Monte Carlo method were proposed to investigate the impact of XS uncertainties on the different radiological inventory response functions.…”

Neutronics design and radiological aspects of HiPER facilities

“…A critical criterion when selecting the reaction chamber material is the waste management [23]. As the reaction chamber will be, together with the First Wall, the most neutron exposed component, its composition has to be carefully chosen to avoid the generation of a radioactive waste with expensive or even undefined management [51]. From the design phase, it has been fixed the need of a definitive waste management option of the reaction chamber viable within the first 50 years after the facility decommissioning.…”
