Resumo
To its utilization as target for radioisotope production, uranium must be properly sealed
before its irradiation in the reactor. For this purpose, aluminum has been a common choice,
due to its chemical compatibility with uranium, reduced neutron cross section and mechanical
stability in corrosive reactor pool environment. However, the use of aluminum in 99Mo
production comprises an alkaline dissolution route, and it not only generates considerable
losses of 99Mo, but produces large quantities of radioactive liquid as waste. In this sense, this
work proposes an alternative route of producing uranium targets, based on replacing the
aluminum with nickel. Uranium was electrodeposited over a nickel substrate and covered by
successive electrodeposited nickel. Watts’s bath and isopropanol were used as electrolytes,
through pulsed electrodepositing methods. The samples were characterized by beta and
gamma counter, XRD, SEM and OM. Although the electrodeposition of nickel over uranium
still needs some progress, the results suggest a promising route of uranium target production.
