VALIDATION OF AXIAL VOID PROFILE MEASURED BY NEUTRON NOISE TECHNIQUES IN CROCUS
نویسندگان
چکیده
Recently a joint project has been carried out between the Paul Scherrer Institut, Ecole Polytechnique Federale de Lausanne and swissnuclear, an industrial partner, in order to determine axial void distribution channel installed reflector of zero power research reactor CROCUS, using neutron noise techniques. The main objective present paper is report on validation results against alternative measurement technique gamma-ray attenuation simulations with TRACE code. For experiments, used CROCUS core Plexiglass water tank. source detector are fixed moved axially keep geometry source/detector arrangement untouched. This key measure effect by gamma due low contrast this technique. compares experimental obtained both techniques, outcomes Even though quantitative fraction estimations not consistent, trends simulation techniques same. discrepancies various related heterogeneous water-air mixture radial sections channel.
