  • Monitoring of neutron and gamma radiation
    Patent number: 5969359
    Abstract: An improved method and apparatus for performing measurements related to spent nuclear fuel burnup is disclosed. The use of temperature- and radiation-resistant semiconductor detectors permits simultaneous monitoring of neutron and gamma ray emission rates from spent fuel, as well as providing axial burnup gradient information. The semiconductor detectors preferably comprise SiC. The method and apparatus provide significant cost reductions, lowered radiation exposures and increased operational safety during spent fuel monitoring operations.
