  • System for hydrogen injection for boiling water reactors (BWRs) during startup / shutdown
    Patent number: 10964436
    Abstract: A system for injecting hydrogen into Boiling Water Reactor (BWR) reactor support systems in operation during reactor startup and/or shutdown. The system the hydrogen injection system includes at least one hydrogen source, flow control equipment, and pressure control equipment. The pressure control equipment being configured to regulate a pressure of a hydrogen flow between the at least one hydrogen source and the at least one first BWR support system based upon an operating pressure of the at least one first BWR support system.
    Type: Grant

  • Methods of controlling hydrogen concentrations in an offgas system of a nuclear reactor by passive air injection
    Patent number: 8105563
    Abstract: Example embodiments relate to methods of controlling hydrogen concentrations in an offgas system of a nuclear reactor by passive air injection. A method according to a non-limiting embodiment may include passively injecting ambient air through the hydrogen water chemistry system into an existing offgas line of the offgas system. The offgas line is configured to transport non-condensable gases, including hydrogen, from a condenser to a recombiner. As a result of the passive air injection, the combined flow of hydrogen and oxygen react in the recombiner to form water vapor, thereby reducing the hydrogen concentration of the offgas exiting the recombiner.
