“…Similarly, Stobes et al 27 observed that reactor radiation had a similar effect on the corrosion of aluminum alloy. Gamma irradiation has also been found to accelerate the development of aluminum oxide on the alloy surface, as stated by Kanjana et al 28 . This is due to the increased density of oxide with extended irradiation and dose time.…”

This study conducted an evaluation of the corrosion behavior of an aluminum alloy utilized in the Isfahan Miniature Neutron Source Reactor (MNSR). The component analyzed, dry channel (DC), had been exposed to radiation for 12 years in a water environment within the reactor pool since its installation. To determine the effect of radiation on the corrosion of the LT-21 aluminum alloy used in the DC, different parts of the pipe were sampled and various tests were performed. These tests included mechanical strengths (impact, and micro-hardening), XRD, TEM, SEM–EDS, and potentiodynamic polarization (PDP). The parameters measured included corrosion potential, corrosion rate, changes in microscopic structure, and mechanical properties of the aluminum alloy along the entire length of the DC. The neutron and gamma dose distribution along the height of the DC, which was 540 cm, was calculated to determine the correlation between the dose distribution and observed corrosion. The study found that the corrosion mechanisms were complex and resulted from the simultaneous presence of the DC in the pool water and radiation from the reactor core. The observed results are presented and discussed in this study.

“…However, there is still much debate among researchers regarding the impact of radiation on material corrosion. Some argue that ionizing radiation does not affect the corrosion behavior of aluminum alloys in water 24 , 25 , while others hold a contrary view that irradiation accelerates the corrosion of aluminum alloys 26 – 28 .…”

“…----pH60 6.5 Since it is common to inhibit the production of the main oxidizing species, such as O 2 , H 2 O 2 , and •OH radicals, by adding an adequate amount H 2 , further calculations simulating a flow of hydrogen were performed. This also allows to simulate possible H 2 production from aluminum-water reactions induced by γ-radiation [18][19][20]. Figure 9 refers to similar calculations in which a hydrogen flow at three different concentrations was simulated in water with pH 60 6.5, 7, and 7.5.…”

The SORGENTINA-RF project aims at developing a 14 MeV fusion neutron source featuring an emission rate in the order of 5–7 × 1013 s−1. The plant relies on a metallic water-cooled rotating target and a deuterium (50%) and tritium (50%) ion beam. Beyond the main focus of medical radioisotope production, the source may represent a multi-purpose neutron facility by implementing a series of neutron-based techniques. Among the different engineering and technological issues to be addressed, the production of incondensable gases and corrosion product into the rotating target deserves a dedicated investigation. In this study, a preliminary analysis is carried out, considering the general layout of the target and the present choice of the target material.
