Abstract
“FULL-CORE“ VVER-440 EXTENDED CALCULATION BENCHMARKVáclav Krýsl, Pavel Mikoláš, Daniel Sprinzl, Jiří Švarný (Corresponding author: pavel.mikolas@skoda-js.cz, Tel: +420 378042828, Fax: +420 378042305) ŠKODA JS a.s., Orlík 266/15, 316 00 Plzeň, Czech RepublicABSTRACTThe calculation benchmark “Full-Core” VVER-440 was proposed few year ago for macro- codes used for neutron-physics calculations for VVER-440 reactors. This 2D benchmark was used to test the power distribution on the pin by pin level for several macro-codes 1. Recently, extension of this benchmark has been proposed 2. In this case the absorption part of control rod is used instead of fuel part for one selected group. The extension of this benchmark was presented at the 25th Symposium of AER in 2015. The reference solution has been calculated by MCNP code using Monte Carlo method and the results have been published in the AER community. In this paper we will compare the available macro-codes results of this extended calculation benchmark.1 V . Krýsl et. al.: ‘Full-Core’ VVER-440 calculation benchmark.
