  1. 1. Enhancing the performance of the Digital Cherenkov Viewing Device : Detecting partial defects in irradiated nuclear fuel assemblies using Cherenkov light

    Författare :Erik Branger; Sophie Grape; Christopher Orton; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DCVD; Nuclear safeguards; Cherenkov light; Nuclear fuel assembly; Partial defect verification; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : The Digital Cherenkov Viewing Device (DCVD) is an instrument used by authority safeguards inspectors to verify irradiated nuclear fuel assemblies in wet storage based on Cherenkov light emission. It is frequently used to verify that parts of an assembly have not been diverted, which is done by comparing the measured Cherenkov light intensity to a predicted one. LÄS MER

  3. 2. Studies of Cherenkov light production in irradiated nuclear fuel assemblies

    Sammanfattning : The Digital Cherenkov Viewing Device (DCVD) is an instrument used by authority inspectors to assess irradiated nuclear fuel assemblies in wet storage for the purpose of nuclear safeguards. Originally developed to verify the presence of fuel assemblies with long cooling times and low burnup, the DCVD accuracy is sufficient for partial defect verification, where one verifies that part of an assembly has not been diverted.
