Advanced transmutation systems require structural materials that are able to withstand high neutron fluxes, high thermal cycling, and high resistance to chemical corrosion. The current candidate materials for such structures are ferritic and ferritic-martensitic steels due to their strong resistance to swelling, good microstructural stability under irradiation, and the retention of adequate ductility at typical reactor operating temperatures.
In parallel, lead bismuth eutectic (LBE) has emerged as a potential spallation target material for efficient production of neutrons, as well as a coolant in the accelerator system. While LBE has excellent properties as a nuclear coolant, it is also highly corrosive to stainless steel.
During Year 2 of the project (2005-2006), extensive investigation was carried out on the deposition of metal nanowires inside the pores as well as the deposition of the top dense layer of alumina.
The following are the specific goals this year for the project:
- To develop the technology to deposit metal nanowires inside nanoporous alumina layers on HT-9 and EP-823 steel.
- To develop the technology to create thick dense alumina layer on metal nanowires created on steel substrates.
