A jet pump for a nuclear reactor includes a riser and an inlet mixer having a set of nozzles and a mixing section for receiving coolant flow from the nozzles and suction flow from an annular space between the reactor vessel and the shroud core. To minimize or eliminate electrostatic deposition of charged particulates carried by the coolant on interior wall surface of the inlet-mixer of the jet pump, and also to inhibit stress corrosion cracking, the interior wall surfaces of the nozzles and mixing section are coated with a ceramic oxide such as TiO2 and Ta2O5 to thicknesses of about 0.5-1.5 microns.
A method for minimizing or eliminating deposition of charged particulates on interior metal wall surfaces defining a coolant flow passage in a jet pump for a nuclear reactor, comprising the steps of:
A method for protecting interior metal wall surfaces defining a coolant flow passage in a jet pump, comprising the steps of:
