Title: Innovations of James P. Sineath in Nuclear Reactor Technology

Introduction

James P. Sineath is a notable inventor based in Summerville, SC (US). He has made significant contributions to the field of nuclear reactor technology, holding a total of 6 patents. His work focuses on enhancing the efficiency and safety of nuclear systems through innovative designs and methods.

Latest Patents

One of Sineath's latest patents is for intermixing feedwater sparger nozzles and methods for using the same in nuclear reactors. These nozzles are designed to mix coolant from different sources together in an outlet, preventing differences in coolant output. Various flow path configurations can be utilized in the nozzle, including a multiple-path configuration with flows from different sources jacketed or concentrically arranged around flows from other sources. Additionally, swirl vanes may be installed in the nozzle to enhance mixing or filter the fluid flow. The design also incorporates diffusers that can passively suction or accelerate flow, similar to a jet pump. Furthermore, these nozzles can be combined with filtration systems, such as trap filters that capture debris based on momentum differences between denser debris and fluid. The filters can utilize magnetic, adhesive, or porous materials to capture debris without obstructing the flow path, and they can be disengaged when clogged to allow coolant to flow around the system.

Another significant patent by Sineath involves vibration-based acoustic flowmeters with a vibration detector that detects vibrations caused by a standing wave. These flowmeters are particularly useful in inaccessible nuclear reactor spaces. The design includes a passage with a constricted opening followed by a widening section, creating turbulence at the outlet that generates a standing wave and vibration. The flow rate of the fluid can be calculated using the length of the passage and known properties of the fluid. Multiple flowmeters with customized physical properties and types can be utilized together for enhanced functionality.
