Title: Innovations of James K. Sawabe

Introduction

James K. Sawabe is a notable inventor based in San Jose, CA. He has made significant contributions to the field of engineering, particularly in the design of systems related to reactor pressure vessels. With a total of 3 patents, his work has had a considerable impact on improving the efficiency and reliability of various engineering processes.

Latest Patents

One of his latest patents is the "Condensing Chamber Design." This apparatus includes a condensing chamber (CC) that maintains a volume of condensate obtained from vapor emitting from a vessel, such as a reactor pressure vessel (RPV). The design features connections to a reference leg (RL), a variable leg (VL), and a vapor or steam leg (SL). The RL connection allows for the flow of the CRD drive water system backfill into the CC, which then overflows into the VL. This innovative design ensures that excess backfill and/or condensate is returned to the vessel, preventing the introduction of non-condensable gas enriched liquid into the RL and improving the reliability of level measurements.

Another significant patent is the "Water Level Measurement System." This system is designed for measuring water levels within a reactor pressure vessel that contains a core and steam separator assembly. The vessel is filled with water to a nominal level above the core. The system includes a reference leg with a column of water above the nominal level and a variable leg with taps positioned below the reference and nominal levels. Monitors are strategically placed to determine differential pressure, indicating the water level in the vessel above the taps. This system enhances the accuracy of water level measurements, particularly when levels fall below certain thresholds.
