| [1] | Information About AER Working Group A on Improvement, Extension and Validation of Parametrized Few-Group Libraires for VVER-440 and VVER-1000| P. Mikoláš | | ŠKODA JS a.s., Pilsen, Czech Republic | | Joint AER WG A and WG B held their fifteenth meeting in Modra – Harmónia, Slovak Republic during the period of 24-25 April 2006. The objectives of the meeting content of presentations and future activities are shortly described in this paper. | kategorie:AERpublikováno:16th AER, 25-29 September 2006, Bratislava, Slovak Republic - No.1.1 | | umístění:| Tomáš Vytiska | | | | | | | |
| [2] | Inclusion of Historical Dependences of Fuel Burn-up Into MOBY-DICK Code| V. Krýsl, P. Mikoláš | | ŠKODA JS a.s., Pilsen, Czech Republic | | The paper briefly describes inclusion of historical dependences of cross sections into MOBY-DICK code. Changes in program and its library are specified, especially from the point of view of programs user. Preliminary testing on assembly level is described and also testing on core level for “transient” loading pattern calculations is demonstrated on examples of 18th and 19th cycles of the Dukovany NPP Unit III. Some features are addressed in the end of the paper. | kategorie:AERpublikováno:16th AER, 25-29 September 2006, Bratislava, Slovak Republic - No.1.2 | | umístění:| Tomáš Vytiska | | | | | | | |
| [3] | Quantitative and Quality Test of Cross Section Library ENDF/B-b2| R. Zajac | | VUJE, Inc., Slovakia | | This article includes a test or in other words data verification of neutron ENDF/B-VIIb2 sub library. The first part consists from the process of preparation ACE files by NJOY 99.90. The starting point of data verification describes needed patches in NJOY 99.90, which are necessary to do for correctly production of ACE files. After the obtaining ACE files follow the test of all ACE files through GODIVA – input file for MCNP. GODIVA is high enrichment sphere of U-235, where tested material is added as impurity. The aim of GODIVA test is to obtain the certainty if produced ACE files are able to run through MCNP.
The second part of this article begins with choose of benchmarks from “International Handbook of Evaluated Criticality Safety Benchmark Experiments, 2005”. From this source of criticality experiments were separated some benchmarks for quality verification of ACE files by MCNP. | kategorie:AERpublikováno:16th AER, 25-29 September 2006, Bratislava, Slovak Republic - No.1.3 | | umístění:| Tomáš Vytiska | | | | | | | |
| [4] | BIPR7 Library Preparation by HELIOS| P. Dařílek | | VUJE, Inc., Slovakia | | Preparation of diffusion data for BIPR7 and PERMAK programs by spectral code HELIOS is described. Calculation sequence and HELIOS calculation tuning are characterised. Characteristics of the calculations are presented. Short comparison with Kurchatov institute results is given. | kategorie:AERpublikováno:16th AER, 25-29 September 2006, Bratislava, Slovak Republic - No.1.4 | | umístění:| Tomáš Vytiska | | | | | | | |
| [5] | Calculation of Isotope Burn-up and Change in Efficiency of Absorbing Elements of VVER-1000 Control and Protection System during Burn-up| O.A. Timofeeva, K.Yu. Kurakin | | FSUE OKB GIDROPRESS, Russia | | The report deals with fast and thermal neutron flows distribution in structural elements of WWER-1000 FA and AR, determination of absorbing isotope burn-up and worth variation in WWER reactor control and protection system rods. Simulation of absorber rod burn-up is provided using code package SAPFIR_95&RC_WWER allowing detailed description of the core segment spatial model. Maximum burn-up of absorbing rods and respective worth variation of control and protection system rods is determined on the basis of a number of calculations considering known characteristics of fuel cycles. | kategorie:AERpublikováno:16th AER, 25-29 September 2006, Bratislava, Slovak Republic - No.1.5 | | umístění:| Tomáš Vytiska | | | | | | | |
