Enhanced FORK Detector for Partial Defect Verification of BWR Fuel Assemblies
2001 (English)In: Symposium on International Safeguards Verification and Nuclear Material Security. Vienna, Austria, 29 Oct. - 2 Nov. 2001., Wien: IAEA , 2001Conference paper (Refereed)
An extensive study on the feasiblity and the range of validity of the fork detector method for partial defect level verification of spent fuel has been accomplished. The range of validity and the limitations have been studied. It has been shown experimentally together with complementary model calculations that by measuring the neutron yield against the operator-declared burnup a verification on the partial-defect level can be attained, but not for all possible cases of spent fuel assemblies. The additional target of operator-data-independent verification cannot be achieved using only a fork detector. The model calculations support the experimental results and add to the confidence in the correction methods applied to the experimental data.
