摘要:Abstract(#br)A new reactor neutron reference field is proposed, which can be used for measurements of spectrum averaged cross sections (SACS). The reference field is identified in the center of a dry irradiation channel surrounded by six 3.3% enriched fuel assemblies assembled in...

摘要:Abstract(#br)Recently, the GNOMER neutron diffusion code was updated to support kinetic simulations. This direct approach to reactor kinetics is further branched into two operational modes: the so-called Lambda mode and the (normal) implicit mode. Both approaches are describ...

摘要:Abstract(#br)The rod insertion method for control rod worth measurement is explained and past as well as recent developments are outlined. The original methodology is updated with a more consistent use of the flux redistribution correction, conversion from dynamic to static ...

摘要:Abstract(#br)A recent experimental irradiation and measurement campaign using containers made from boron nitride (BN) at the Jožef Stefan Institute (JSI) TRIGA Mark II reactor in Ljubljana, Slovenia, has shown the applicability of BN for neutron spectrum characterization and...

摘要:Abstract(#br)Recently a series of test irradiations was performed at the JSI TRIGA Mark II reactor for the Fission Track-Thermoionization Mass Spectrometry (FT-TIMS) method, which requires a well thermalized neutron spectrum for sample irradiation. For this purpose the Monte Carl...

摘要:Abstract(#br)Absolute average capture cross sections of gold, thorium, tantalum, molybdenum, copper and strontium in 252 Cf spontaneous fission neutron spectrum were simulated for two types of experiment setups preformed by Z. Dezso and J. Csikai and by L. Green. The experim...

摘要:Abstract(#br)The EURACOS experiment series (sodium, iron, and no shielding) has been re-evaluated in the scope of the OECD/NEA SINBAD project to determine how useful these benchmarks can be for the validation of the modern nuclear data evaluations. The measured activation ra...

摘要:Abstract(#br)The calculation of axial neutron flux distributions with the MCNP code at the JSI TRIGA Mark II reactor has been validated with experimental measurements of the 197 Au(n,γ) 198 Au reaction rate. The calculated absolute reaction rate values, scaled according to t...

摘要:Abstract(#br)Covariance data in the existing evaluated nuclear data libraries often include large relative uncertainties and mathematical inconsistencies, which arise especially in combination with random sampling. The 232 Th evaluation from the ENDF/B-VII.1 library has been take...
