Flow accelerated corrosion Mass transfer Orifice Pipe wall thinning Schmidt number
In this paper, experimental and numerical studies are carried out to understand the pipe-wall thinning caused by the flow accelerated corrosion behind an orifice in a circular pipe. The measurement of mass transfer coefficient is carrie d out using a wall material of benzoic acid in a water flow, which allows the measurement of mass transfer behind the orifice in a circular pipe at Schmidt number 300 and 700, which is comparatively close to the actual condition in the prototype pipeline of nuclear power pl...

chemical decontamination coat platinum recontamination
Noble metal chemical addition (NMCA) technology has been widely adopted for BWR plants in the US as a means to mitigate stress corrosion cracking (SCC). Dose rate of the reactor water recirculation system piping of some BWR plants that apply a combination of NMCA and zinc injection technology have gradually decreased. Chemical decontamination removes 60Co, but also the noble metal from the piping surfaces. Thus, effect of dose rate reduction by NMCA is decreased in the plant operating period after che...

Flow accelerated corrosion Mass transfer Nuclear power generation Orifice Pipe-wall thinning Swirling flow
In this paper, pipe-wall thinning phenomenon behind an orifice in a circular pipe is studied by measuring the mass transfer coefficient along the pipe wall by naphthalene sublimation method. An attention is placed on the asymmetrical pipe-wall thinning phenomenon behind an orifice under the influence of swirling flow and allowable orifice bias. The present measurement indicates that the mass transfer coefficient becomes asymmetric about the pipe axis behind the orifice in certain combinations of swirl...
