Latest Patents

One of Larsen's notable inventions is the "Material Surveillance Specimen Holder for Core Shroud of Boiling Water." This device is designed to conduct a surveillance program by monitoring the effects of radiation and high-temperature oxygenated water on the shroud material within an operating reactor. The holder securely contains shroud material specimens and encapsulated neutron flux monitors, being installed on the shroud wall for a predetermined reactor operation period. After this period, the holder is removed to allow laboratory examination of the specimens, enabling researchers to analyze any changes in material properties.

Another significant invention is the "Self-Aligning Seal System for Maintenance Service in Nuclear Reactors." This innovative seal system facilitates the repair or replacement of components in recirculation pump assemblies that penetrate the bottom head of the reactor pressure vessel. It allows operators to block off stub openings while performing maintenance in a dry field, without having to drain the coolant water from the reactor. To prevent leakage caused by misalignment, the self-aligning guide member provides a centering function for the sealing unit, enhancing operational safety and efficiency.
