Neutronic study of extended DONES irradiation module

In this work, radiation conditions behind the irradiation module, the so-called High Flux Test Module (HFTM), are analyzed with a double objective. First objective is to assess the impact of the second irradiation module on the material irradiation effects in the HFTM due to its potential use as optimization tool for the damage dose and gas production in the specimens. Second objective is to assess on the potential use of that volume for irradiation of additional specimens beyond the HFTM. Then, neutron transport calculations have been performed in order to evaluate the impact on the irradiation effects on the HFTM and to determine the radiation level in the experimental samples of the new module.
