113. A New Approach for the Application of the Self-Interrogation Neutron Resonance Densitometry (SINRD) to Spent Fuel Verifications

Riccardo Rossa (SCK-CEN; ULB)

oral

The verification of spent nuclear fuel is one of the activities performed by the International Atomic Energy Agency (IAEA), and the development of innovative non-destructive assays (NDA) is one of the fields of research in the safeguards community. In this framework the Belgian nuclear research center SCK•CEN started the investigation of the Self-Interrogation Neutron Resonance Densitometry...

Because of the large amount accumulation of spent fuel, a research to solve the spent fuel problem is actively performed in Korea. One option is to develop the SFR linked with the pyro process to reuse the existing fissile materials in spent fuel. Therefore, an accurate isotopic fissile content assay becomes a key factor in the reuse of fissile material for safety and safeguards purpose. There...

38. Application of Passive Gamma-ray Spectroscopy for Special Nuclear Material Accountancy in Molten Core Material of Fukushima Daiichi Nuclear Power Plant

Yusuke Kuno (JAEA)

oral

For the nuclear material accountancy of molten core material in Fukushima Daiichi unit 1, 2 and 3, feasibility studies of variety of technologies are being performed in JAEA. As one of the technologies, feasibility study of passive gamma spectroscopy of low-volatile fission products (FPs) for nuclear material accountancy in molten core material has been performed with reviewing TMI-2...

179. Uncertainty Quantification of Fork Detector Measurements from Spent Fuel Loading Campaigns

oral

With increasing activities at the end of the fuel cycle, the requirements for the verification of spent nuclear fuel for safeguards purposes are continuously growing. In the European Union we are experiencing a dramatic increase in the number of cask loadings for interim dry storage. This is caused by the progressive shut-down of reactors, related to facility ageing but also due to politically...

189. A Prototype for Passive Gamma Emission Tomography

Tapani Honkamaa (STUK)

oral

Combined efforts of multiple stakeholders of the IAEA Support Programme task JNT 1510: “Prototype of passive gamma emission tomograph (PGET)”, resulted in the design, manufacturing and extensive testing of an advanced verification tool for partial defect testing on light water reactor spent fuel. The PGET has now reached a proven capability of detecting a single missing or substituted pin...

237. U and Pu Gamma-Ray Measurements of Spent Fuel Using a Gamma-Ray Mirror Band-Pass Filter

Klaus-Peter Ziock (Oak Ridge National Laboratory)

oral

We report the use of grazing incidence gamma-ray mirrors as narrow band-pass filters for advanced non-destructive analysis of spent nuclear fuel. The mirrors limit radiation reaching an HPGe detector to narrow spectral bands around characteristic emission lines from fissile isotopes in the fuel. Ideally, these emissions could be used to determine the fuel's fissile content, but they are...
