NUCLEAR DATA UNCERTAINTY PROPAGATION FOR A TYPICAL PWR FUEL ASSEMBLY WITH BURNUP

Determination of the Transuranic Elements Inventory in High Burnup Pwr Spent Fuel Samples by Alpha Spectrometry

Determination of transuranic elements such as U, Pu, Np, Am and Cm in spent nuclear fuels is of importance for a fuel characterization, evaluation of a burnup credit, and burnup determination of spent nuclear fuels. Additionally, the exact amount of the actinide elements, as the major elements of a source term, of the spent nuclear fuels is also used for a code verification that predicts the am...

Modelling of Fission Gas Behaviour in High Burnup Nuclear Fuel

The safe and economic operation of nuclear power plants (NPPs) requires that the behaviour and performance of the fuel can be calculated reliably over its expected lifetime. This requires highly developed codes that treat the nuclear fuel in a general manner and which take into account the large number of in uences on fuel behaviour, e.g. thermal, mechanical, chemical, etc. Although many mature...

Cfd Prediction of Pressure Drop for the Inlet Region of a Pwr Fuel Assembly

Computational Fluid Dynamics (CFD) has been widely used in pressure drop/hydraulic loss calculations in many industries, including the aerospace and turbo-machinery industry as well as in the nuclear power industry. During the past 30 years, a significant amount of time and effort have been spent in benchmarking the CFD tools and models against test data in aerospace and turbo-machinery industr...
