Electrochemical and spectroscopic characterization of oxide films formed on Alloy 182 in simulated boiling water reactor environment: Effect of dissolved hydrogen

Abstract

In boiling water reactor (BWR) environments, the content of dissolved hydrogen (DH) in the high-temperature water has an influence on the stress corrosion cracking (SCC) susceptibility of Ni-based alloys. In order to understand the possible role of different types of surface oxide films in the SCC initiation process, oxide films formed on Alloy 182 weld metal under simulated BWR conditions at 274°C with varying contents of DH from 10 to 2200 ppb, were investigated by electrochemical and spectroscopic methods. The influence of the DH content on the nature of the oxide films is discussed in the context of SCC mechanisms.

Use of Nano Fluids in Nuclear Technology: A Review

“…Heating of nano-fluids is the simplest way to achieve upgrade top (George et al, 2015). Nanofluids play significant role in various interesting applications of nuclear power plants (Bai et al, 2018). There is a poor understanding about efficiency of nanofluids, paradigmatic reactor requirements and suitability of the nano-fluids with acquired materials of the reactors (Bhogare and Kothawale, 2013).…”

“…Types of nuclear reactors. Nuclear reactor systems include Light water reactor (LWR), pressurised water reactor (PWR), and Boiling water reactor (BWR) (Bai et al, 2018).…”
