ELECTROCHEMICAL CORROSION POTENTIAL PROBE ASSEMBLY

PROBLEM TO BE SOLVED: To provide an electrochemical corrosion potential probe assembly for monitoring water chemistry within a nuclear reactor system.SOLUTION: An electrochemical corrosion potential (ECP) probe assembly 100 for monitoring ECP in pipes of a high flow rate nuclear reactor includes an airfoil-shaped ECP cover 114 that improves the streamlines over and around an ECP sensor. The airfoil-shaped cover includes flow holes drilled normal to the surface of the ECP cover 114. As such, the direction of flow of reactor water into the ECP probe assembly 100 is altered to reduce the flow rate internal to the ECP cover 114 sufficiently to prevent damage to the ECP probes 110. To facilitate use as a retrofit component, the ECP cover 114 may have an elliptical section that is contiguous to a circular section that conforms to the geometry of existing probe wells and probe sub-assemblies.
