Abstract

Radiation damage evaluations have been performed with the ACAB code for fusion-relevant materials in an Ignitor-like compact fusion device that could be used as a neutron source for materials testing. Values ranging from 1.6 × 10-26to 2.4 × 10-25dpa per source neutron have been obtained, which translates into 16-250 dpa/y at full operating power and demonstrates the potential of this neutron-rich device for fusion materials testing. It will be shown that only a few full-power months of operation with a feasible operating duty cycle are sufficient to obtain relevant radiation damage values in terms of dpa. An estimate of the radiation damage on selected machine components will be presented, and solutions to solve the problem of radiation damage to the insulator of the toroidal field insulator will be discussed. © 2011 Elsevier B.V.
