摘要

Abstract

An analysis of the neutron activation and shutdown dose rates was performed for the EAST high-power deuterium neutral beam injector test facility (EAST NBITF) by using the multiparticle transport code FLUKA 2011.2. Also, the neutron and neutron-induced gamma spectra of the facility’s vacuum vessel were evaluated. The results identified the major radionuclides ,99,Mo,65,Ni,58,Co,56,Mn, and,51,Cr for the vacuum vessel and the primary nuclide ,64,Cu for both the ion dump and the calorimeter. The simulated results indicated that, when the EAST NBITF operates within the design parameters of deuterium energy 80 keV, current 50 A, and pulse 100 s, the neutron intensity will achieve 10,11,n/s with no radiation safety problems after the EAST NBITF shuts down for 1 h.
