Abstract:
1. A method for reducing deposition of charged particulates on a conductive surface defining a wetted portion of a coolant flow passage in a nuclear reactor, comprising the steps of: forming a base dielectric layer by exposing the conductive surface to a first organometallic precursor compound under conditions sufficient to decompose the precursor compound and form a substantially continuous base dielectric layer on the conductive surface, the base dielectric layer consisting essentially of at least one tantalum (Ta) compound; and forming an outer dielectric layer by exposing the base dielectric layer to a second organometallic precursor compound under conditions sufficient to decompose the precursor compound and form a substantially continuous outer dielectric layer on the base dielectric layer, the outer dielectric layer consisting essentially of at least one titanium (Ti) compound.
