Abstract
AER X2 BENCHMARK DRAFT DECISION WITH USE OF PARCS CODEM.Ieremenko, I.OvdiienkoState Scientific and Technical Centre on Nuclear and Radiation Safety, Kyiv, Ukraine Stusa st. 35-37, 03142 Kyiv, Ukraine yn_ovdienko@sstc.com.uaABSTRACTAt the 19th AER symposium a benchmark on core burnup calculations for VVER-1000 reactors with loadings of TVSA fuel assemblies was proposed for further validation and verification of the reactor physics code systems.This report presents the results of benchmark’s TASK 1 and TASK 2 decision with use of PARCS code for 1st fuel cycle. The given results consist of the 3D core burnup calculation together with calculations of critical states for hot zero power conditions. Also there are solutions for reactivity effect calculations for different reactor states and the analysis of critical boron acid concentrations, 2D power density and burnup distributions.The work was performed in the framework of the project BMUB/GRS 3614R01520 under German BMU support.26th Symposium of AER on VVER Reactor Physics and Reactor Safety 11 10 – 14 October 2016, Helsinki, Finland
