  • Enriched boron-10 boric acid control system for a nuclear reactor plant
    Patent number: 5291530
    Abstract: A nuclear reactor plant is provided in which the reactor coolant system contains a dissolved solution of enriched boric acid. The boron-10 to boron-11 atomic isotope ratio of the enriched boric acid solution is greater than 19.8:80.2 at the start of the reactor core cycle. The nuclear reactor plant design provides for minimal mixing between the reactor coolant solution containing the enriched boric acid solution and the natural boric acid solution used during refueling operations.
    Type: Grant
    Filed: April 1, 1991
    Date of Patent: March 1, 1994
    Assignee: Westinghouse Electric Corp.
    Inventors: Albert J. Impink, Jr., Joseph A. Battaglia, John W. Fasnacht, George G. Konopka
  • Enriched boron-10 boric acid control system for a nuclear reactor plant
    Patent number: 5271052
    Abstract: A nuclear reactor plant is provided in which the reactor coolant system contains a dissolved solution of enriched boric acid. The boron-10 to boron-11 atomic isotope ratio of the enriched boric acid solution is greater than 30:70 at the start of the reactor core cycle. The nuclear reactor plant design provides for minimal mixing between the reactor coolant solution containing the enriched boric acid solution and the natural boric acid solution used during refueling operations.
