Estimated Target Accuracies for Neutronic Responses in Fusion Reactors

摘要

Neutronics responses play an important role in plant design, in that way that they determine dimensions of components, the lifetime of components, the thermal power produced, and ultimately the electricity cost. Most system studies contain sufficient information to derive cost sensitivities for the main neutronic responses, which then can be used for the estimation of target accuracies. Target accuracies for the energy-multiplication of the blanket, the tritium breeding ratio, the radiation damage and radiation heating of the superconducting coils and the dose rate behind the biological shield, have been calculated for three UWMAK studies, the PPPL, and the reversed field pinch of Culham and Los Alamos.
