dc.description.abstractUptake of radioactive 60Co2+ in nuclear reactor cooling loops poses a problem in nuclear power plants. Unattended oxide films on 316L stainless steel results in an outer formation of iron-nickel spinel crystalites and inner iron-chromium spinel layer. The outer crystalites incorporate the radioactive isotope 60Co, which has a half life of 5.3 years, from cooling water. The issue is as of today addressed through zinc injection or the patented Hi-F Coat, the latter is a elecroless deposition method of hematite and magnetite. The Hi-FC is a subject of modification to exclude chemicals harmful to the user and the environment. Hematite does not allow for uptake of 60Co2+ and therefore this study will aim to via electroless deposition, deposit a hematite layer for applications in nuclear power plants cooling loops. A successful implementation of this will lower the radiation dose experienced within the cooling loop with up to 90% and drastically reduce the associated health risks and maintenance costs.
