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

    Author : Erik Branger; Sophie Grape; Christopher Orton; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Erik Branger; Sophie Grape; Anders Hjalmarsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DCVD; Cherenkov light; Geant4; Nuclear fuel; Nuclear safeguards; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : 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.

  5. 3. Determination of Sr90 and the Transuranium Elements in the Event of a Nuclear Accident

    Author : Ingvar Friberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transuranium TRU elements; nuclear accident; Sr90; solvent extraction; radioanalysis; HDEHP; Cherenkov; DMDBTDMA;

    Abstract : To reduce the health effects of a nuclear accident, it is essential that suitable analytical methods are available for determinations of radionuclides released to the environment. Sr90 and the transuranium (TRU) elements are of great radiological importance, and they are more difficult to measure than many other radionuclides. READ MORE
