Abstract: Nozzles mix coolant from different sources together in an outlet to prevent differences in coolant output. Different flow path configurations are useable in the nozzle, including a multiple-path configuration with flows from different sources jacketed or concentrically arranged around flows from other sources. Swirl vanes may be installed in the nozzle to impart mixing or filtering the fluid flow. Diffusers may be used to passively suction or accelerate flow and mixing the same like a jet pump. Nozzles can be combined with filtration systems like trap filters that capture debris based on a momentum difference between the denser debris and fluid. Filters can use magnetic, adhesive, or porous materials to capture debris without blocking a flow path. Filters can be disengaged, such as when clogged, such that coolant flows around the system. Nozzles can be installed on feedwater sparger assemblies in varying manner to distribute coolant from multiple nozzles.

Abstract: An electrochemical corrosion potential (ECP) probe assembly for monitoring ECP in a high velocity reactor line includes an airfoil shaped ECP cover 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. As such, the direction of flow of reactor water into the ECP probe assembly is altered to reduce the flow rate internal to the ECP cover sufficiently to prevent damage to the ECP probes. To facilitate use as a retrofit component, the ECP cover 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.
